Buyers of early Radeon RX 7900 XT and XTX suspect that AMD is releasing unfinished graphics cards



Some Radeon RX 7900 series graphics cards from the first batch may have been released based on the structurally unfinished Navi 31 GPUs. This assumption was made by some enthusiasts among the early buyers of the Radeon RX 7900 XTX and RX 7900 XT.

AMD’s Navi 31-based Radeon RX 7900 graphics cards with the new RDNA 3 architecture are positioned as competitors to NVIDIA’s GeForce RTX 4080 graphics cards. The older model Radeon RX 7900 XTX in independent gaming tests really turned out to be faster than its competitor, but only by 4% on average. The difference is so small that some AMD fans were disappointed. In addition, in ray-traced games, the new Radeons are still far behind NVIDIA solutions. Some enthusiasts believe that the first batch of Radeon RX 7900 XTX and RX 7900 XT graphics cards are based on GPUs with an initial revision of the A0 core.

Twitter user alias Kepler_L2 found information in the Radeon driver code indicating that some Navi GPUs have preloaded hardware shaders disabled by software.

This unpleasant feature is typical for three chips marked GFX1100, GFX1102 and GFX1103. The first is the older Navi 31, on the basis of which the Radeon RX 7900 XTX and RX 7900 XT are produced. The second and third are the yet-to-be-released Navi 33 and Navi 32, which will form the basis of the Radeon RX 7800, as well as other next-generation AMD desktop and mobile graphics cards.

Also, users report a strange situation with fluctuations in the operating frequencies of the new Radeon graphics cards. For example, @uzzi38 noticed that the Radeon RX 7900 XTX GPU in games can run at frequencies from 2.4 GHz to 2.9 GHz without any changes to the game settings.

And in the analysis of the video card by the TechPowerUp portal, it is indicated that the difference in frequencies can be even more significant. For example, in games, the chip worked at frequencies from 1934 to 2994 MHz, and in the same Furmark stress test, which was supposed to squeeze all the juice out of the GPU, the GPU frequency turned out to be even lower – 1660 MHz.

Video blogger Nadalina shared a similar observation. She noted that in Call of Duty: Modern Warfare 2, the graphics chip of her ASUS Radeon RX 7900 XT TUF Gaming graphics card worked in the frequency range from 2.4 to 2.9 GHz with the same quality settings. Initially, the card selects high GPU frequencies, but drops to 2.4GHz after about an hour of play, resulting in a performance drop of about 20%. In this case, after restarting the game, high FPS values ​​\u200b\u200bare returned. Nadalina’s complaint was brought to the attention of AMD Head of Gaming Solutions and Marketing Architect Frank Azor, who promised to look into the matter.

The difference in GPU frequencies under different loads is a fairly common phenomenon. The frequency directly depends on the load level and GPU temperature. But such a significant difference under the same loads looks very strange.

The aforementioned TechPowerUp review also states that the Radeon RX 7900 XTX consumes 103W of idle power when using multiple monitors when the competition requires less than 50W. For example, the GeForce RTX 3090 Ti requires only 42W under these conditions, while the GeForce RTX 4080 and GeForce RTX 4090 require 23W and 27W, respectively.

High power consumption problems can be fixed with the new driver, which cannot be said about the initial revision A0. Here, the only solution may be to release the graphics core at a new stage, which is unlikely to please the first buyers of the Radeon RX 7900 series video cards. According to reports, a disabled hardware shader preloader deprives Radeon graphics of the previous generation. cards based on the RDNA 2 architecture, the performance is about 5%. It remains to be seen how its absence will affect the performance of video cards based on the RDNA 3 architecture. Now it remains to wait for official comments from AMD itself.

‘My power is really low’: NASA’s Mars Insight rover prepares to launch from the Red Planet



NASA Lander InSight He has delivered what may be his last message from Mars as he embarks on a historic mission to uncover the secrets of the Red Planet’s interior.

In November, the space agency warned that the probe could be running out of time as dust continued to condense and stifle InSight’s power.

“Spacecraft power generation continues to decline as windblown dust accumulates on solar panels,” NASA said in a statement. Update November 2. “The end is expected to come in the coming weeks.”

message shared NASA The InSight Twitter account tweeted on Monday: “My power is very low so this might be the last photo I can upload. Don’t worry about me: my time here has been productive and uneventful. If I can keep talking to my mission team, I will—but I will.” Subscribe here soon. Thank you for staying with me.”

My power is very low, so this might be the last photo I can upload. But don’t worry about me: my time here has been productive and uneventful. If I can keep talking to my mission team, I will, but I’ll sign here soon. Thank you for staying with me.

A geologist robot armed with a hammer and a seismograph first reached the barren expanse of Elysium Planitia in November 2018.

Since then, she has carried out geological excavations, taking the first measurements of earthquakes with a high-tech seismometer placed right on the surface of Mars.

Last month, the solar-powered car released an update to remind us of its time in space.

“I was lucky to live on two planets. Four years ago I made it safely to the second one, much to the joy of my family at first. Thanks to my team for taking me on this journey of discovery. I hope I can be proud of you.”

According to the published mission, Insight has measured more than 1,300 seismic events since it was published, and more than 50 of them had signals clear enough for the team to extract information about their location on Mars. Results.

The probe’s data also provided detailed information about Mars’ interior, liquid core, surprisingly variable remnants beneath the surface of an extinct magnetic field, climate and seismic activity.

old for Its launch in 2018NASA Chief Scientist Jim Green said the mission was “fundamental to understanding the origins of our solar system and how it became what it is today.”

NASA will not declare the mission complete until Insight confirms the arrival of two spacecraft orbiting Mars that are relaying their information back to Earth.

In 2018, the veteran rover announced the capabilities end of his 15 year stay Sending an incomplete photo of the Valley of Perseverance.

A severe dust storm darkened the sky around the solar-powered rover, shattering the sun and leaving behind a dark image with white spots due to camera noise. The transmission is interrupted before the complete image can be transmitted.
