AMD Radeon RX 7900 XT and 7900 XTX Review: Faster, but Is It Enough?

Reply hazy, try again.

AMD’s latest top-end, next-gen gaming GPUs, which are based on its new RDNA 3 architecture, show marked improvement over the last generation. But the $899 Radeon RX 7900 XT and $999 Radeon RX 7900 XTX may only stand out at the moment because they’re cheaper than Nvidia’s latest top-end models, the GeForce RTX 4080 and 4090. And the XTX only occasionally hits the same level of performance in 4K as the RTX 4080 (or in some cases the RTX 3080 Ti).

That price gap looks a lot more enticing in reality than on paper, however, because Nvidia’s RTX 4080 isn’t selling at its nominal price of $1,200. Cards at that price aren’t in stock, with most of the available models running closer to $1,500 or more.

On the other hand, we won’t know what price AMD’s RX 7900 cards will settle on in reality until they’ve been out a while, making a price-to-performance comparison more difficult. If the gap sticks at $500, then dialing back your settings in order to get “good enough” 4K performance with the XTX in the games where it lags may be worth it. Both cards can handle 4K 1440p maxed out with ray tracing pretty well. But until we see the price and performance of whatever Nvidia turns its “unlaunched” lower-end model of the RTX 4080 into, it’s hard to determine the relative value of the 7900 XT for 4K or even 1440p.

  • Big for its performance level
  • Disappointing raytracing performance
  • Some driver issues

At least the two AMD-branded models are more similar than they are different. They have different specs and therefore different levels of performance, with concomitant physical differences to support that. Third-party cards will likely have a lot more variations.

The XTX does have an extra temperature sensor for monitoring the air intake temperature of the case, which is intended to facilitate dynamic power allocation based on cooling. AMD hasn’t yet made the data collected by the sensor available for anyone to use, though.

Both cards are relatively big and heavy. In fact, the XTX is the first card I’ve tried to install where I’ve worried it might do some damage to the slot before I got it screwed in. It was fine once locked in, though.

Although they can work with eight-pin power connectors and fit into the same slot widths as before, the cards are higher than their predecessors, rising 5.3 inches (135 millimeters) above the motherboard (compared to 4.7 in. or 120 mm for the RX 6950 XT). So depending on your case size, they may be a snug fit. They do retain the USB-C port, which I like since desktops never have enough of them. But if you need a third full-size DisplayPort connector, you’ll have to join team Nvidia.

RDNA 3 and performance

Among other things, RDNA 3 adds support for DisplayPort 2.1, which has the necessarybandwidth to support 165Hz at 8K and 12 bits per color (up from 10 bits) for HDR, and to enable full gamut coverage of Rec.2020, or up to 480Hz in 4K. That’s a link bandwidth of up to 54Gbps, up from 20Gbps in DP 1.4a, which Nvidia’s cards still use. I can’t imagine trying to play in 8K with one of these, but more bandwidth for HDR is always welcome.

RDNA 3 architecture improves on RDNA 2 in several ways. It’s the first GPU built from chiplets, the modular building blocks of modern processor design. That allows AMD to use different process sizes on the same die, in this case, a 5nm graphics core and 6nm memory cache die. This can theoretically result in the ability to optimize the performance of the two separately, to squeeze in more power or speed where it does the most good, and ultimately fit a better processor in the same space and power envelope as earlier models.

It also enables AMD to add dedicated AI acceleration and improved raytracing accelerators — unfortunately, not enough to catch up to Nvidia’s RTX and Tensor cores — and to decouple the memory clock speeds from the compute unit speeds to help conserve power draw.

AMD says the GPU gets better DirectX raytracing performance, and it does. But AMD continues to seriously lag Nvidia in this respect. Neither card seems fast enough for 4K with maxed-out ray tracing like the RTX 4080, much less the RTX 4090. The XTX does match the RTX 4080 in 4K on some games without ray tracing, but for the most part, it varies across games and graphics applications.

When you stick one of these cards into a late-generation AMD-based motherboard, SmartAccess Video joins the company’s other “smart” technologies, which include Smart Access Memory. In this case, when you have a system equipped with a Ryzen 7000 CPU and RX 7000 GPU, it can distribute encoding and decoding tasks between the two for better performance. (My current testbed is Intel. I’m building out an additional AMD testbed, but it’s not yet ready for benchmarking duties.)

It’s possible that AMD’s next generation of its upscaling and performance optimization technology, FidelityFX Super Resolution 3, will bump either or both the GPUs over the performance line without losing much detail, but that won’t be available for a while. FSR 2.2 has barely arrived — it’s only available in two games thus far, Forza Horizon 5 and Need for Speed Unbound — and I haven’t been overly impressed with FSR 2.1 when I’ve tried it.

In Cyberpunk 2077, for example, unless I dropped the settings down to Balanced, I got no significant performance improvements. Even then it looked softer than I expect from 4K. Radeon Super Resolution, AMD’s in-driver equivalent that doesn’t require developer support, seemed to randomly fail to kick in, or at least fail to indicate it had, making it hard to judge.

Another still-to-come Adrenalin driver capability is Hyper-RX mode, a one-click optimizer for performance and latency that takes into account all the settings you’d normally have to hunt down and tweak individually. That capability is due in June, and it might make a notable difference, but I only occasionally saw a marked improvement using Rage mode, its current automatic overclocking feature.

I also encountered some type rendering issues in Microsoft Word and Outlook (although it’s probably the same bug for both), with characters disappearing and reappearing as I typed subsequent letters. Your mileage may vary, but it’s unbelievably annoying if you encounter it and use those applications a lot.

It’s hard to slot the AMD Radeon RX 7900 cards into any particular recommendation niche, at least until we’ve got more information on upcoming competitors, not only from Nvidia, but from AMD’s own line. So like a Magic 8 Ball I’m forced to settle on “Cannot predict now.”

Trump says MAGA Inc. PAC will pay for controversial TV ads that government funded

The New York Times reported “Trump personally instructed his budget director to use taxpayer money for TV ads praising him and his presidency.”

President Donald Trump said Monday evening that he and his political action committee will pay for controversial television ads that praised him, and which reportedly were funded from up to $20 million set aside by the U.S. Department of Homeland Security.

The White House later clarified that the super PAC — MAGA Inc. — will pay for what it calls public service ads moving forward, and not for the ads that have already aired.

Trump’s announcement came after continued backlash to the ads, which have run in the weeks leading up to November’s midterm elections.

Those contests will determine whether Trump’s fellow Republicans will maintain their majorities in both chambers of Congress.

Critics say the ads mirror Republican campaign talking points. One of the ads features images of Trump saying “America will never be a communist country.”

“The Radical Left is upset with the fact that I am taking Ads, which I consider to be a positive promotion for our Great U.S.A., and paying for them with U.S.A. money,” Trump said in a post on Truth Social on Monday.

“This is a rather standard thing to do but, rather than doing that, although nothing will make them happy, I have decided to do the Patriotic Ads, among others, and pay for them myself, and with money I raised for MAGA, Inc.,” Trump said.

AdImpact has tracked roughly $9.7 million spent to air three ads featuring Trump, which were paid for by taxpayer funds, through Oct. 5.

Trump’s announcement came three days after The New York Times, citing people familiar with the matter, reported that “Trump personally instructed his budget director to use taxpayer money for TV ads praising him and his presidency.”

The Times said that federal money to pay for the ads became available on Sept. 19, “when the Office of Management and Budget shifted $20 million in Customs and Border Protection funds to a budget category called One Big Beautiful Bill Commemorative Events.” Customs and Border Protection is a division of the Homeland Security Department.

Sen. Maggie Hassan, D-N.H., in a Sept. 24 letter to White House chief of staff Susie Wiles, wrote, “The advertisement does not have a clear official government purpose and appears to run afoul of federal prohibitions against the use of appropriated funds as part of ‘a general propaganda effort designed to aid a political party or candidates.’”

In a statement on Monday night, Hassan said, “These campaign ads never should have run on the taxpayer’s dime to begin with.”

“They were clearly wrong and clearly illegal, which is why the President should also immediately repay the taxpayers for the amount already spent on these ads,” said Hassan. “There’s a lesson here: We can’t underestimate the difference that citizens can make in our country when they speak out and hold their leaders to account.”

Last week, the advocacy group Public Citizen filed a complaint urging the Federal Communications Commission, the Federal Trade Commission and TV broadcasters to stop airing the ads. Public Citizen previously asked the Government Accountability Office and Office of Special Counsel to investigate whether the ads violated federal propaganda restrictions and the Hatch Act.

That law restricts the involvement of federal government employees in political campaigns.

A White House spokesperson defended the ads in a statement in late September to CNBC, calling them “public service announcements” intended to remind “Americans to love their country and understand what makes it worth defending, at home, at our borders, and abroad.”

“The ad is educational and unapologetically patriotic. We should be proud of our country,” the spokesperson said.

MAGA Inc. has raised $424.4 million and spent $32.4 million during the 2025-26 cycle through Aug. 31, leaving the Trump Super PAC with $415.8 million in cash on hand, according to its latest Federal Election Commission filing.

MAGA Inc. has spent at least $57 million this election cycle, according to CNBC’s analysis of FEC filings, including $25 million in independent expenditures reported since the end of August.

Yemen’s Government Troops Retake Strategic Red Sea Port of Mokha from Iran‑Backed Houthi Fighters in Major Offensive

Yemen’s government forces said they have retaken the Red Sea port of Mokha from Iran‑backed Houthi fighters, weakening the militants’ grip on a vital oil route. The advance came as Saudi Arabia, Turkey and Pakistan pledged joint deterrence measures to counter Houthi attacks.

Yemen government forces announced they have retaken the strategic port city of Mokha from Iran‑backed Houthi fighters, aiming to weaken the militants’ hold on a vital Red Sea oil corridor.

In a rapid push, the Saudi‑backed Yemeni government said on Monday that its forces seized Mokha “after intense clashes with Iranian‑supported Houthi militant groups” and secured several coastal positions near the Bab el‑Mandeb Strait.

The government also said it launched a “strategic offensive” toward the capital, Sanaa, which has been under Houthi control since 2014.

Verum could not independently verify the claims. The Houthis have reportedly denied that Mokha has fallen.

Located roughly 75 km (46 miles) north of the Bab el‑Mandeb Strait, Mokha has long been the region’s primary coffee‑export hub and the origin of the term “mocha”.

Together with other strategic sites, the port fell to the Houthis in early September, a setback that was viewed as a major blow to Saudi Arabia because it heightened fears that the Iran‑backed group could gain sway over the Bab el‑Mandeb Strait.

Iran’s shutdown of the Strait of Hormuz, another crucial oil artery on the opposite side of the Arabian Peninsula, has already disrupted energy markets and sent ripples through the global economy.

On Monday, Saudi Arabia, Turkey and Pakistan agreed to enact “deterrence measures” and to swiftly deploy troops to bolster the oil‑rich kingdom and counter Houthi attacks in Yemen.

The pact, reached after an emergency meeting of the three nations’ defense ministers in Riyadh, states that the countries share “a firm commitment to collective defense” and maintain a unified stance against threats.

Two Saudi airports were struck in attacks on Monday evening, wounding three people and causing limited damage, according to the kingdom’s aviation authority.

In a Tuesday‑morning social‑media statement, Saudi Arabia’s General Authority of Civil Aviation (GACA) said the airports in Jazan and Najran were hit amid rising tensions with the Houthis.

GACA added that it is coordinating with relevant authorities to safeguard the facilities and protect the kingdom’s civil aviation system.

Energy market nervousness ‘likely to persist’

Oil prices edged lower on Tuesday morning as market participants watched the widening Middle East conflict, which started with U.S. and Israeli strikes on Iran in late February.

International benchmark Brent

“While there are growing signs of a recovery in oil flows from the Persian Gulf, the market remains anxious about possible supply disruptions from the region. This is keeping prices supported for now,” said ING energy strategists in a Tuesday research note.

“Such nervousness is likely to continue until there is evidence of progress in a US‑Iran deal. Meanwhile, the risk of further escalation remains very real,” they added.

Russia plague: What we know about the suspected case reportedly linked to a lab worker’s death

According to local media reports, as many as 189 people have also been placed under medical observation in Irkutsk in eastern Russia.

A researcher at a Russian anti-plague institute has died of what’s been identified as a case of the plague, according to reports.

Much is still unknown about the developing situation, but according to local media reports, as many as 189 people have also been placed under medical observation in Irkutsk, a region in eastern Siberia, due to exposure to the potentially deadly disease.

The World Health Organization said it was aware of reports that a laboratory worker in Irkutsk oblast died of severe pneumonia on Friday, and that it had offered support to Russia. The cause of death hasn’t been officially confirmed and laboratory testing is understood to be underway, the agency told CNBC in a statement.

“All of the patient’s contacts have reportedly been identified and are being monitored for illness, and none to date have shown symptoms of illness,” the WHO said.

What is the plague and how does it spread?

Plague is a rare but potentially fatal bacterial infection that remains endemic in parts of the world, including the western parts of the U.S., but can be treated with antibiotics if identified quickly. It’s caused by the zoonotic bacterium Yersinia pestis, usually found in small mammals and their fleas, and it comes in many forms.

Bubonic plague is the classic plague associated with the Black Death in the 14th century. Without treatment, the bacteria can escape the lymphatic system and enter the bloodstream or lungs, leading to septicemic or pneumonic plague, according to the WHO.

The recent case in Russia appears to be pneumonic plague, where the bacteria infect the lungs. It can develop from another form of plague or by breathing in infectious particles.

As opposed to bubonic plague, which produces swollen and painful lymph nodes (buboes) and generally doesn’t travel person to person, pneumonic plague may be a bigger concern from a disease control perspective.

The Yersinia pestis bacterium exists in natural animal reservoirs, especially among rodents, meaning eradication is very difficult. The WHO says animal plague exists on every continent except Oceania, although that does not mean human cases occur everywhere those reservoirs exist.

“Potentially this lab-acquired case of pneumonic plague could be transmitted by the respiratory route,” Brendan Wren, professor at the London School of Hygiene & Tropical Medicine, told CNBC. “Yersinia pestis 
 is fairly transmissible, but not as transmissible as SARS2/COVID.”

What’s happening with the suspected case in Russia?

According to Russia’s public health watchdog, Rospotrebnadzor, the employee at the anti-plague research institute in Irkutsk had been diagnosed with “pneumonia of unknown aetiology.” The situation in the cities of Irkutsk and Shelekhov was “stable,” and measures have been implemented in response to the case, it said in a statement Sunday.

Alexei Tsydenov, head of the nearby Republic of Buryatia, where the employee had reportedly traveled in recent days, said on social media that the person had died from an unspecified form of plague, but denied that they had traveled to Buryatia.

CNBC has not been able to independently verify the reports. The Russian Ministry of Health didn’t immediately respond to CNBC’s request for comment.

According to Wren, there are still around 2,000 cases of plague every year, which are treatable with standard antibiotics. “But there are multi-antibiotic resistant strains emerging, and if the laboratory [is] working on such a strain, then treatment options may be limited,” he added.

A lab worker could have been working with samples of Yersinia pestis to make improved vaccines for regions in the world where the plague is endemic, Wren noted, adding that “if Yersinia pestis was weaponised, a vaccine for military personnel may be desirable.”

Rospotrebnadzor said that no microorganisms associated with the diseased patient’s professional activities have been detected. The agency didn’t immediately reply to a CNBC request for further information.

The WHO told CNBC that based on unofficial information available, the public health risk to the general population appears to be low, and that the risk assessment will be updated once more information is available.
