The Arc A770 will be Intel's top-of-the-line model, with 32 Xe cores (equivalent to 4,096 stream processors) running at ~2,100 MHz and coupled with 8GB or 16GB of GDDR6 memory with a peak bandwidth of 560 GBps. 

The CEO of Intel confirmed at Intel Innovation that the A770 will cost $329.  Recall that the A770 includes an ACM-G10 GPU with 32 Xe-Cores and 8GB to 16GB of memory. However, the Intel Limited Edition includes 16GB of VRAM. Intel says that this GPU offers up to 65 percent greater peak performance in ray tracing than competitor devices (probably the NVIDIA RTX 3060 series). Unfortunately, there is currently no information regarding the availability of A750. 

The cards will become available on October 12th with a starting price of $329. intel didn't share much other then it's 65% better in peak performance versus competition in Ray tracing. Not saying what card they are comparing too, but likely the RTX 3060 (Ti) range of performance. We hope Intel's A770 is worth buying when they're released. Nvidia and AMD offer affordable GPUs and are already prepping to release a new generation of products. It is also worth noting that NVIDIA will release their RTX 4090 GPU on the same day.
