It seems that the review kit distributed to overseas media this time included the VRAM 16GB model of Arc A770 and the lower model 'Arc A750'. The specs of both are as follows. Both GPUs support ray tracing, and the upsampling function ' XeSS ' is also available.

Below are the results of Ars Technica benchmarking with multiple GPUs including Arc A770 and Arc A750. The Arc A770 beats the RTX 3060Ti in all three benchmarks except Fire Strike Ultra, and the Arc A750 also beats the RTX 3060Ti in Time Spy and Time Spy Extreme.
The number of frames per second (fps) when running the open world game '
On the other hand, when running '
The table below summarizes the results of XDA Developers' verification of the effects of the supersampling function 'XeSS'. ' Shadow of the Tomb Raider ' has better fps with XeSS on, but ' DEATH STRANDING ' has lower fps. XDA Developers commented on this result, 'XeSS seems to be still in development.'
Also, Intel's Arc series includes an AV1 encoder, but according to XDA Developers, as a result of outputting a 4K60fps movie of about 4 minutes and 30 seconds using the Arc A770's AV1 encoder, it was output with an H.264 encoder. It is said that it succeeded in reducing the weight of 200 MB with the same image quality as the movie.
Below is a table summarizing the number of processed frames per minute when HotHardware renders CG images with the 3DCG software 'Blender'. The Arc A770 and Arc A750 seem to be able to process more frames than the RX 6600XT, but less than the RTX 3060.
As mentioned above, the Arc A770 and Arc A750 perform as well or better than the RTX 3060 depending on the application. However, when 'Resizable BAR', which makes PCIe communication more efficient, is disabled, it has been confirmed that performance drops. For example, Ars Technica encountered a phenomenon that ``the display of the web browser is disturbed and becomes unusable'' in an environment where Resizable BAR is disabled.
