Intel A770 Graphics Limited Edition Teardown
Recently, Tom Petersen, Intel’s academician responsible for graphics technology innovation, accepted an interview with HotHardware. Many details of the upcoming Arc A7 series graphics cards have been revealed, but unfortunately, no specific release time has been provided.
Tom Petersen introduced the overclocking capability of the ARC Alchemist (DG2) discrete graphics card, saying that the ARC A770 graphics card can overclock the GPU clock from 2.1GHz to above 2.7GHz without special selection, as long as the voltage is properly optimized, Hitman 3 can run smoothly. At this time, the power consumption of the graphics card is 228W, which is only 3W higher than the default power consumption, the speed of the fan has not changed, and the temperature can be controlled at about 80 degrees Celsius.

In addition to overclocking, Intel detailed the cooler design for its Intel-branded graphics card (IBC) Arc A770 Limited Edition. Arc A770 Limited Edition uses a 6-phase VRM power supply, connected through PCIe 4.0 x16 interface, equipped with an 8+6Pin external power supply interface. The display output interface includes three DP 2.0 interfaces and one HDMI 2.1 interface, and the fan noise is 39 decibels. It is based on the ACM-G10 chip, with 32 Xe cores of Xe-HPG architecture, the clock is 2100MHz, the video memory is 16GB GDDR6 (partners will also provide an 8GB version), the video memory bit width is 256 bits, and the speed is 17.5Gbps, the memory bandwidth is 560GB/s.

It is worth reminding that the RGB lighting effect is unique to the Arc A770 Limited Edition, and the Arc A750 Limited Edition does not have it. In addition, the HDMI 2.1 interface needs to be implemented through PCON. If the partner does not have such a converter, only the HDMI 2.0 interface can be provided.
