Blackwell launch gets even worse as Nvidia confirms some RTX 5090 and RTX 5070 Ti GPUs are underperforming in games – here's how to check if you're affected
Nvidia has confirmed that approximately 1 in 200 of its RTX 5090 and RTX 5070 Ti GPUs have an issue with their graphics chips
The problem is a loss of ROPs, a key element of the inner workings of the GPU
Nvidia says those with an affected graphics card should contact the maker to arrange a replacement
Following reports of some RTX 5090 GPUs failing to perform as well as they should in gaming, Nvidia has confirmed that there is an issue with the chips in the Blackwell flagship, as well as the newly arrived RTX 5070 Ti GPU.
This is a hardware-level problem, meaning it's a fault deep in the chip which can't be fixed, and it's slowing down these graphics cards by an appreciable (albeit variable) amount.
In a statement addressing the matter, Nvidia told The Verge: "We have identified a rare issue affecting less than 0.5% (half a percent) of GeForce RTX 5090 / 5090D and 5070 Ti GPUs which have one fewer ROP than specified.
"The average graphical performance impact is 4%, with no impact on AI and Compute workloads. Affected consumers can contact the board manufacturer for a replacement. The production anomaly has been corrected."
Your first question may well be: what's a ROP, then? ROP stands for Raster Operations Pipeline, and this is hardware that's a key part of the process of rendering the graphics for your PC games. (It's a lot more complicated than that, in reality, but that's all you really need to know).
With fewer of those pipelines available to deal with the relevant graphics processing tasks during gameplay, unsurprisingly, performance is a bit slower.
Also, if you're wondering about the mentioned RTX 5090D, that's the variant of the Blackwell flagship sold in China, which was involved in the initial reports of this issue – notably the RTX 5070 Ti wasn't, though.
This whole episode unfolded yesterday, having first emerged courtesy of TechPowerUp's review of a Zotac RTX 5090 Solid graphics card (via VideoCardz).
In its review, the tech site found that this third-party model was somehow underperforming versus an Nvidia RTX 5090 Founders Edition (the performance baseline used by TechPowerUp in gauging the relative power of the flagship GPU variants).
Indeed, the Zotac RTX 5090 was around 5% slower than Nvidia's own model, while running at the same clock speeds, which obviously didn't make much sense. Not until TechPowerUp investigated and found this wasn't an issue pertaining to faulty cooling (or other likely-seeming root causes), but in fact that the Zotac GPU was missing ROPs.
The RTX 5090 graphics card was showing 168 ROPs enabled (in the GPU-Z utility) rather than the expected count (and official spec) of 176 ROPs.
All vendors are potentially affected by this gremlin in the works, of course, as this is an issue with the chips produced by Nvidia, and sent to third-party partners to be used in the manufacturing of their graphics cards. That was swiftly shown yesterday as reports started to come in, as folks started checking their boards for this issue.
While in its statement, Nvidia mentions the lack of one ROP, it is referring to one block of them, so as observed, the ROP count is reduced by eight (the number in a block) with graphics cards that have this issue.
To check your RTX 5090 or 5070 Ti, you can fire up a tool that peers deep into the innards of your hardware, monitoring and reporting back on multiple elements of the spec. Obviously what you're looking for is the ROPs count, and that can be provided by GPU-Z as already mentioned, or an alternative utility like HWiNFO (and probably other software out there, no doubt).
In GPU-Z, you'll find the ROPs number listed in the Graphics Card tab, on the seventh line down, over on the left-hand side (we've got an explainer here, if you want further details on GPU-Z). For the RTX 5090, the number should be 176, whereas 168 is what the impaired flagship models are showing. With the RTX 5070 Ti, the correct spec is 96 ROPs, so in theory, it will be reduced to 88 ROPs (but I haven't seen confirmation of that yet, so perhaps it could have less of an impact).
If you do have an RTX 5090 or 5070 Ti with this problem, how much will it affect you in practical terms? Well, that varies as I already mentioned, although as stated the average impact is a performance loss of something in the order of 5% (or thereabouts – Nvidia is saying 4%).
However, you may not notice any difference at all in some cases, as one game may use the mentioned pipelines (ROPs) more heavily, while another may hardly touch them at all. So some games could be slowed down by more than 5%, and others may have a negligible loss in frame rates (such a low impact you'd never be able to tell).
However, before you go thinking that maybe this isn't such a big deal after all, rest assured, it is. A fault like this should not have cleared quality assurance and made it into production hardware in the first place. And when you recall how much buyers have forked out for the RTX 5090 in particular – the MSRP is a true wallet-worrier, and many folks have overpaid beyond that – well, you can start to see how this is a big letdown.
If you have an RTX 5090 or RTX 5070 Ti, check your graphics card in GPU-Z as outlined above. If your model is showing a loss of ROPs, as advised by Nvidia, contact your board manufacturer and begin the process of having the graphics card replaced.
That could be a troublesome matter, though, for those who may have sold their old GPU when they upgraded (if they need to send the faulty Blackwell graphics card back, before receiving a new one – and are left with a gaming PC without an engine, essentially). The other worry is that it's not like fresh stock is going to be easy to come by, either, right now.
Future GPUs shouldn't suffer from this issue because as Nvidia observes, the 'production anomaly' here has been fixed, as you would hope.
Nvidia is investigating reports of crashes plaguing RTX 5090 and 5080 GPUs, with possible driver issues maybe hitting RTX 4000 models too
Finally, some good news about Nvidia's new GPUs: RTX 5090 stock levels rumored to surge in a month or so

Nvidia Hits $4 Trillion--And It's Still Just Getting Started
Nvidia (NVDA, Financials) just crossed a milestone no company ever has before; on Wednesday, it became the first public firm in history to hit a $4 trillion market cap. Shares popped 2.5% to an all-time high of $164; the message from Wall Street is clearAI is here, and Nvidia is leading the charge. Warning! GuruFocus has detected 4 Warning Signs with NVDA. This time last year, Nvidia had just hit $1 trillion; now, in just over 12 months, it's quadrupled that figurefaster than either Apple (AAPL, Financials) or Microsoft (MSFT, Financials) ever managed. Once known for gaming GPUs; then for powering crypto mining rigs; Nvidia has reinvented itself againnow as the engine room of global AI infrastructure. The company now carries the biggest weight on the S&P 5007.3%; that's more than Apple; more than Microsoft. The stock is up 22% year-to-date; and after getting knocked down in Aprilthanks to Trump-era tariffs and Chinese AI jittersit's bounced back fast, gaining 74% from those lows. That rebound wasn't just hype; Q1 revenue jumped 69% to $44.1 billion, with earnings of 81 cents per share. And for Q2, Nvidia expects $45 billion in revenue, give or take 2%; it'll report those numbers on August 27. Despite the monster rally, the stock trades at a forward P/E of 32below its three-year average of 37; that suggests investors don't think it's overheated just yet. With that kind of trajectoryand dominancesome would argue this is Nvidia's world now; the rest of us are just living (and computing) in it. This article first appeared on GuruFocus.

Stock market today: Dow, S&P 500, Nasdaq jump as Nvidia's surge to milestone boosts tech
US stocks rose on Wednesday as Nvidia (NVDA) shares jumped to a fresh all-time high, with the AI chip maker becoming the first company to ever cross a $4 trillion market cap. The Dow Jones Industrial Average (^DJI) rose nearly 0.5%, while the S&P 500 (^GSPC) gained 0.6%. The tech-heavy Nasdaq Composite (^IXIC) rose 0.9% to close at a fresh record of 20,611.34. Nvidia (NVDA) stock also closed at a new record after taking the crown of the most valuable company in history. It crossed the $4 trillion market cap level early in Wednesday's session but ended the day slightly below the milestone level. Markets edged higher in the face of ramped-up trade rhetoric from President Trump. It stood in contrast to the reaction on Monday and Tuesday, which saw the S&P 500 drop after Trump posted letters outlining new tariff rates on Japan and 13 other countries. On Wednesday morning, Trump unveiled more notices with tariff rates ranging from 20%-30% to countries such as the Philippines, Libya, Algeria, and Iraq ahead of an Aug. 1 deadline to reimpose country-specific tariffs. Trump has said "no extensions will be granted" to countries that have not struck deals before then.

Fed minutes released on Wednesday afternoon showed only "a couple" of Federal Reserve officials at the June meeting supported interest rate cuts as soon as this month. At the June meeting, policymakers held interest rates steady, leading traders to bet that two rate cuts this year are likely. Stocks edged higher as Nvidia (NVDA) touched a $4 trillion market cap during Wednesday's session — reaching a new milestone as the most valuable public company in the world. The Dow Jones Industrial Average (^DJI) rose nearly 0.5%. The S&P 500 (^GSPC) gained 0.6% while the tech-heavy Nasdaq Composite (^IXIC) rose 0.9% to close at a fresh record as most of the 'Mag 7' megastocks gained. Shares Nvidia closed up 1.6%, a new high. The gains came despite increased trade tensions as President Trump posted more tariff letters on social media directed at US trading partners. Yahoo Finance's David Hollerith reports: Read more here. Yahoo Finance's Pras Subramanian reports: Read more here. Fed minutes released on Wednesday afternoon showed "a couple" of officials at the June meeting supported interest rate cuts as soon as this month. "Most participants assessed that some reduction in the target range for the federal funds rate this year would likely be appropriate," the minutes said, noting that "upward pressure on inflation from tariffs may be temporary or modest, that medium- and longer-term inflation expectations had remained well anchored, or that some weakening of economic activity and labor market conditions could occur." The minutes released on Wednesday afternoon give investors a glimpse at what Fed officials may do when they meet later this month. The market currently forecasts that a rate cut would not come earlier than September, despite President Trump's vocal calls for Fed Chair Jay Powell to cut rates. Yahoo Finance's Jake Conley reports: Read more here. Stocks trimmed gains after President Trump posted a new batch of tariff letters on Wednesday, directed at US trading partners. The Dow Jones Industrial Average (^DJI) gained 0.1%, while the S&P 500 (^GSPC) edged up 0.3%. The tech-heavy Nasdaq Composite (^IXIC) rose 0.7%, after gaining as much as 1%. The notices of tariffs on imports from US trading partners went out to the following countries. The rates ranged from 20%-30%. As Yahoo Finance's Ben Werschkul reported, the list focused on lower-level trading partners. The Philippines was the biggest announcement Wednesday, but that nation ranks about 30th in US trading partners by value, according to US government data. The rates continued a trend of rates being announced this week that largely tracked what was first announced in April, with some alterations. The Philippines, for example, saw its proposed rate jump slightly from 17% to 20%. Starbucks (SBUX) stock jumped as much as 2% at the market open Wednesday after a report from CNBC suggested that the company has had multiple offers for its China business, including the likes of Centurium Capital, Hillhouse Capital, and US private equity firm Carlyle Group. "We see significant long-term potential in China and are evaluating the best ways to capture the future growth opportunities," a Starbucks spokesperson told Yahoo Finance. "We are looking for a strategic partner with like-minded values ... and want to retain a meaningful stake in the business." The business there has struggled to compete with top rival Luckin Coffee's low-price model. It has a store base of more than 20,000 stores, compared to Starbucks' nearly 8,000 stores in the region. Starbucks China's same-store sales growth fell as much as 14% in both the third and fourth quarters last year before rebounding to flat in the latest quarterly results, thanks to a 4% increase in transactions that was offset by a 4% decline in the average ticket size. A source told Yahoo Finance that lower prices announced last month have boosted sales in the afternoon and evening there, and zero-sugar options have increased the frequency of visits among customers. Analysts expect same-store sales to increase 2.49% for Starbucks China in its next quarterly report, per Bloomberg consensus estimates. Shares are up more than 5% year to date, trailing slightly behind the 6% gain from the S&P 500 (^GSPC). M&A dealmaking is beginning to rebound, and deals linked to artificial intelligence are leading the way. CoreWeave's (CRWV) planned acquisition of data center infrastructure provider Core Scientific (CORZ) marked the latest big-ticket AI M&A announcement this year as large companies with room on their balance sheets look to make a splash in a burgeoning industry.

US copper (HG=F) prices retreated 3% Wednesday, backing off fresh records touched in the prior session as the market grappled with President Trump's threat to put a 50% tariff on imports of the metal. Copper imports have soared in recent weeks as the industry anticipated tariffs on imports. Industry insiders say the US currently brings in 50% of the copper it needs from abroad. Tariffs on those imports would considerably increase prices across an array of industries which utilize the metal — from data centers, to electrical grids to autos. Nvidia (NVDA) stock gained more than an intraday record high on Wednesday, becoming the first company to ever hit a market cap of $4 trillion. The AI chipmaker's valuation has now surpassed Apple's (AAPL) record market cap of $3.91 trillion reached in December 2024. At roughly 9:40 a.m. ET, Nvidia shares hovered near a record of $164, building on its closing high of $160 in the prior session. US stocks nudged higher on Wednesday as investors awaited more details on President Trump's latest tariff announcements, including the possibility of 50% levies on copper imports.

Nvidia (NVDA) stock gained another 0.6% in premarket trading Wednesday, building on its record closing price the prior day of $160. Its market capitalization of $3.90 trillion is just shy of Apple's (AAPL) record market cap of $3.91 trillion reached in December 2024. Today's moves also put Nvidia ever closer to becoming the first company to have a valuation north of $4 trillion. Shares rose on Tuesday, even after the broad indexes dipped and President Trump mentioned that chip tariffs may be in the offing soon. In the past month, Nvidia stock is up nearly 13% as hyperscalers and other customers remain committed to spending on artificial intelligence infrastructure. As Yahoo Finance's Francisco Velasquez pointed out, Nvidia's sovereign AI deals offer another reason for bullishness, as analysts estimate they are already contributing billions of dollars in revenue this year.

A large dose of chaos has been injected into copper markets following President Trump's threat to impose 50% tariffs on copper imports. Copper prices surged on Tuesday and remain near a record. I would keep an eye on top copper stocks such as Freeport-McMoRan (FCX) and Southern Copper Corp. (SCCO) today. Here are some of Wall Street's early reactions: Goldman Sachs' Eoin Dinsmore "Given the increased risk of a 50% tariff, we expect a further acceleration in shipments into the US in the coming weeks, as the incentive to front-run the tariff implementation has increased. With the Dec-25 COMEX-LME arbitrage now trading at ~$3,000/ton — pricing an implied ~30% tariff — we keep our long Dec-25 COMEX-LME arbitrage trade recommendation open. As we recently highlighted, there was a meaningful risk of a 50% tariff, which is now playing out. In time, the copper tariff may revert to 25%, but steel and aluminium tariff increased to 50% in June, and markets have priced around 80% of those tariffs, factoring in uncertainty on potential future exemptions - which suggests copper should move to price a 40% import tariff in Dec-25." Jefferies' Christopher LaFemina "Trump's announced 50% tariffs on copper imports came as a surprise in terms of timing and magnitude, but tariffs were likely coming at some point. Higher copper prices in the US should ultimately incentivize growth investment in mines and new smelters/refineries. We believe the longer term aim of the Trump administration may be for the US to be fully self-sufficient in copper, but mines take too long to develop for this to be achieved in less than a 10-year time horizon, in our view. Getting there faster from a smelting/refining perspective is possible and would erode a competitive advantage that China currently has in the copper supply chain. However, as we discuss in this note, the US will still rely on foreign mines to meet demand for the foreseeable future. It is therefore possible that tariffs on refined copper imports will persist for a relatively long duration, which is what we have seen in the US steel industry following the roll-out of section 232 tariffs for steel by President Trump in 2018." Keep an eye on telecom stocks today, after some cautious comments out of KeyBanc. T-Mobile US (TMUS) caught most of the ire of analyst Brandon Nispel in a downgrade to underperform. "We think underperformance [in the stock] will continue for these reasons: 1) we think TMUS is fiber deficient in a converged/bundled world; 2) we think the near-term macro/competitive environment limits upside to expectations; 3) we think TMUS's consumer value proposition has deteriorated due to recent pricing actions, which suggest TMUS shouldn't take outsized share of the industry net adds; and 4) we think TMUS will relatively benefit the least from tax changes due to the One Big Beautiful Bill," Nispel said. Nispel maintained sector-weights on shares of Verizon (VZ) and T-Mobile, but voiced concern about rising competitive activity holding back financial results this year. Here's what T-Mobile CEO Mike Sievert recently told me on industry phone-plan prices.

A large dose of chaos has been injected into copper markets following President Trump's threat to impose 50% tariffs on copper imports. Copper prices surged on Tuesday and remain near a record. I would keep an eye on top copper stocks such as Freeport-McMoRan (FCX) and Southern Copper Corp. (SCCO) today. Here are some of Wall Street's early reactions: Goldman Sachs' Eoin Dinsmore "Given the increased risk of a 50% tariff, we expect a further acceleration in shipments into the US in the coming weeks, as the incentive to front-run the tariff implementation has increased. With the Dec-25 COMEX-LME arbitrage now trading at ~$3,000/ton — pricing an implied ~30% tariff — we keep our long Dec-25 COMEX-LME arbitrage trade recommendation open. As we recently highlighted, there was a meaningful risk of a 50% tariff, which is now playing out. In time, the copper tariff may revert to 25%, but steel and aluminium tariff increased to 50% in June, and markets have priced around 80% of those tariffs, factoring in uncertainty on potential future exemptions - which suggests copper should move to price a 40% import tariff in Dec-25." Jefferies' Christopher LaFemina "Trump's announced 50% tariffs on copper imports came as a surprise in terms of timing and magnitude, but tariffs were likely coming at some point. Higher copper prices in the US should ultimately incentivize growth investment in mines and new smelters/refineries. We believe the longer term aim of the Trump administration may be for the US to be fully self-sufficient in copper, but mines take too long to develop for this to be achieved in less than a 10-year time horizon, in our view. Getting there faster from a smelting/refining perspective is possible and would erode a competitive advantage that China currently has in the copper supply chain. However, as we discuss in this note, the US will still rely on foreign mines to meet demand for the foreseeable future. It is therefore possible that tariffs on refined copper imports will persist for a relatively long duration, which is what we have seen in the US steel industry following the roll-out of section 232 tariffs for steel by President Trump in 2018." Keep an eye on telecom stocks today, after some cautious comments out of KeyBanc. T-Mobile US (TMUS) caught most of the ire of analyst Brandon Nispel in a downgrade to underperform. "We think underperformance [in the stock] will continue for these reasons: 1) we think TMUS is fiber deficient in a converged/bundled world; 2) we think the near-term macro/competitive environment limits upside to expectations; 3) we think TMUS's consumer value proposition has deteriorated due to recent pricing actions, which suggest TMUS shouldn't take outsized share of the industry net adds; and 4) we think TMUS will relatively benefit the least from tax changes due to the One Big Beautiful Bill," Nispel said. Nispel maintained sector-weights on shares of Verizon (VZ) and T-Mobile, but voiced concern about rising competitive activity holding back financial results this year. Here's what T-Mobile CEO Mike Sievert recently told me on industry phone-plan prices.
