The severity of this vulnerability is moderate and there is a risk of denial of service or information disclosure.

Attaches a detailed description as follows:

 CVE-2022-41984: Certain Iris A770 / A750 graphics cards have a hardware protection mechanism failure where a privileged user can enable denial of service, CVSS Base Score 4.4 (Medium).

 CVE-2022-38973: Certain Iris A770/A750 graphics cards may allow denial of service for authenticated users via local access, or improper access control in information disclosure scenarios, with a base CVSS score of 3.3 (low).

In both cases above, the user is allowed to exploit the vulnerability through local access, and the attacker can launch a DoS attack.

However, as of press time, Intel has not stated in the announcement whether it will release firmware updates or patches but advises consumers who purchase these two graphics cards during October-December 2022 to contact the Intel product support department in their region for assistance.

This change only affects the “limited edition” (which can be interpreted as the public version), which means that all non-public graphics cards will continue to remain as they are, and you can still buy non-public Arc A770 16GB graphics cards from major brands.

After this card is discontinued, there will only be three Arc A770 16GB models left on the market, including the Acer Predator Bisfrost and the two Blue Halberds.

In addition, Intel is also offering 8GB models (8GB is only available in non-public versions) to its AIB partners, and at least four models are already available in this configuration.

In terms of parameters, Intel’s flagship graphics card, the Razzle A770 Limited Edition, features 32 Xe cores and is marked with a GPU frequency of 2100MHz.

Other aspects, the card comes with up to 16GB of 17.5Gbps 256bit GDDR6 memory, 225W TDP, 8+6pin power supply, three DP 2.0 ports and one HDMI 2.1 port.

As shown above, the ARC A750 in the latest driver support, whether 1080p or 1440p, “Return of the Dead” and “Worker’s Story: Emerging Alliance” two new works on the frame rate are better than the RTX 3060 12GB graphics card.

rogue-lite shooting game “Return of Death (Returnal)” has officially launched on the PC platform (previously exclusive by PS5), has opened a pre-order on Epic and Steam platform, the Chinese region 379 yuan, support Chinese interface and subtitles.

Ubisoft’s newest entry in the legendary build-and-build real-time strategy game series, Workers’ Story: Emerging Alliance, is now available on PC (Ubisoft International Store) for $298 for the standard edition.

Intel announced earlier this month that the global price of the ARC A750 public version of the graphics card will be adjusted from $289 to $249 (currently about RMB 1,698). In China, the price of the ARC A750 public version of the graphics card Jingdong recently dropped from RMB 2499 to RMB 2199, and now it has dropped to RMB 1999 yuan.

Tests from PC Games Hardware show that Microsoft’s DirectStorage API can help NVMe SSDs load game material significantly faster than SATA SSDs. they also provide a huge advantage of GPU-based decompression over CPU decompression.

The site runs Microsoft’s publicly available Avocado loading DirectStorage demo on SATA SSDs, PCIe 3.0 NVMe SSDs, and PCIe 4.0 NVMe. It also compares decompression speeds between three GPUs and CPUs – AMD Radeon RX 7900 XT, Intel Arc A770, NVIDIA GeForce RTX 4080, and 5.2GHz Intel i9-12900K.

The chart below shows the transfer rates in GB/s for each hardware configuration, showing the average results across the five tests. Here, the NVMe SSD is several times faster than the SATA SSD, while PCIe 4.0 has a slight advantage over PCIe 3.0. Perhaps most curiously, the A770 outperforms the RX 7900 XT and 4080 in terms of GPU decompression, even though it is the underdog in terms of gaming performance.

The screenshots in the demo show the difference between CPU and GPU decompression. Some screenshots show several gigabytes of material taking between 1.5 and 5 seconds to load, with CPU utilization ranging from 30% to 100%. Others show the same material loading in about half a second with less than 5% CPU utilization, indicating that the GPU has taken over the job.

The demo showed promising early results for hardware outside of Microsoft Labs. In addition, they showed a huge shift in 2020 testing, showing that recent games have not taken full advantage of the bandwidth benefits of NVMs over SATA drives.

At GDC in March, Square Enix claimed that DirectStorage allowed Forspoken to load new scenarios and environments in less than 2 seconds on NVMe SSDs, compared to a few seconds on SATA SSDs and nearly half a minute on HDDs. Microsoft has designed new APIs for Windows 11. Windows 10 systems will see only limited benefits due to its legacy storage stack.

According to the news, Intel today announced the launch of a new “Xe” kernel graphics driver, which is targeted to take effect in 2023, in order to better support modern Xe graphics hardware in Linux.

Intel’s open-source Linux graphics driver engineers have long been working on a new Direct Rendering Manager driver for Gen12/Xe graphics cards, hoping to bypass the i915 driver. For most of the past 20 years, the i915 driver has performed relatively well and has been adapted to Intel’s Arc graphics card.

However, the “i915” graphics driver has become very bloated after nearly 20 years of development, and Intel hopes to provide a future-proof, more minimalistic driver. Intel’s new “Xe” DRM kernel graphics driver will support Gen 12 (starting from the 11th generation Tiger Lake) and later processors as well as Intel Sharp (Arc) discrete graphics.

The video CapFrameX used in this test is a video called “Japan in 8K 60fps”. To initiate a proper capture on CapFrameX software, the application entry “chrome” needs to be removed from the application’s ignore list to find an appropriate capture and provide performance results.

Also, while playing a video, right-clicking on the video pulls up a menu list and also needs to provide a click on “Stats for nerds” so we can see the stats.

Here are the stats for CapFrameX:

The first AV1 test results are the average frame rate per second and the 1% and 0.2% percentile FPS of the four graphics cards

While Intel was the leader in the test, delivering 60 fps, the NVIDIA GeForce RTX 3090, RTX 4090, and RTX 3080 all delivered the same 59.9 fps for video. The AMD Radeon RX 6800 XT came in last, delivering 55.8 fps, a difference of 4.1 to 4.2 fps on the 4K resolution 60 fps test.

The test results of the “Japan in 8K 60fps” video in 8K resolution are as follows:

The Intel Arc A770 graphics card still topped the charts for AV1 encoding, producing 59.9 fps in 8K video. The NVIDIA GeForce RTX 4090, 3090, and my 3080 came in at 57.6, 56.8, and 56.7 fps, respectively, suggesting that NVIDIA’s support for AV1 encoding is better than the last-place AMD Radeon RX 6800 XT, which only managed 22 fps.

CapFrameX also provides Chrome AV1 8K video decode frame times, which shows that the AMD Radeon RX 6800 XT emits huge spikes of over 800ms every 4 seconds of video. Meanwhile, the Intel Arc A770 graphics card held the lead during the test and improved slightly at the end.

Because of this, Intel emphasizes that their graphics cards are more cost-effective, and even the light tracking performance is 65% higher than that of competing products, which is quite confident.

Everyone has seen the first evaluations at home and abroad. To a certain extent, Intel has not exaggerated the advantages of the A770 graphics card. The performance can indeed exceed the RTX 3060, and the cost performance is also very high. However, this is also conditional.

The PCMag website summed up a few points, pointing out that if the A770 wants to beat the RTX 3060, the platform and the game must be considered. Specifically, the platform processor/motherboard should be relatively new, and the reBAR technology should be supported. The game should be DX12 or Vulkan. Support RT light pursuit, not old games such as DX11 or DX9.

After these conditions are met at the same time, the performance of the A770 and A750 graphics cards can be better displayed, otherwise, the performance will be seriously affected, especially the reBAR technology, which greatly affects the game performance of the A770/A750 graphics card when turned on and off, and can even affect the game performance. 30% to 50% performance.

Despite partnering with the latest discrete GPU maker, Acer’s foray into the discrete GPU space marks the beginning of an interesting area for it – at least from a design perspective.

The new Arc A770 BiFrost features asymmetrical dual fans and industrial design details such as RGB lighting in the inclusion. The card’s design is somewhat reminiscent of NVIDIA’s design for its founder version, with some visible screws breaking the visual coherence. It also features a dual 8-pin power supply circuit, proving that it will certainly be more powerful than Intel’s public version of the Arc A770.

Acer is known for its pre-built desktops, laptops and monitors and now seems to want to dip its toe into the discrete GPU market. Unfortunately, Acer’s release today lacks details; there’s only a rendering of the graphics card and no actual specs on whether the company will offer an 8GB version of the Arc A770, its 16GB variant or both. Whether the company intends to extend its reach to other Arc models, or even other manufacturers such as AMD and NVIDIA, is unknown, but it’s understandable that it would first try the easy way out at a single, single vendor. GPUs are a slightly more complex board component on PCs, and the company would certainly prefer to test the waters first rather than fully commit to an area that is still new to them.

Of course, we still hope the company takes the Asus/Gigabyte approach and offers graphics cards from different manufacturers instead of just one. It looks like some companies are stepping up to further fill the market space in the GPU board business, even as others such as longtime GPU player EVGA have just announced their breakup with NVIDIA.

Not only is there light supplementation, but Intel also has its own XeSS technology, similar to NVDIA’s DLSS or AMD’s FSR 2.0, which also uses AI to accelerate game performance.

The A750 graphics card has 24 Xe cores with 256-bit 8GB of video memory.

The public version uses dual fans to dissipate heat, and the surface also uses a skin-like touch, which looks more refined. The front of the A770 and A750 are exactly the same, but they can be easily distinguished by the lettering on the back. Also, the A770 has RGB lights, while the A750 doesn’t.
