Intel Arc A780
Intel Arc A780: Highlights
Intel Arc A780 is a desktop Graphics Processor produced by Intel. It was launched in December 2022. The DG2-512 graphics processor is an average-sized chip with a die area of 406 mm², 21700 million transistors count, and TDP is 200W. It features 4096 shading units, 256 texture mapping units, and 128 ROPs.
The Arc A780 has 32 raytracing acceleration cores, and the fabrication process is TSMC 6nm. Arc A780 has paired 16 GB GDDR6X memory and uses a 256-bit memory interface. Arc A780 operates at a base frequency of 2200 MHz, which can be boosted up to 2200 MHz, and memory runs at 1093 MHz (17.5 Gbps effective).
