The specifications of Intel’s 1st Gen Arc alchemist mobile GPUs have leaked out (courtesy of Videocardz). These SKUs will target the entry-level and midrange mobility graphics market with performance ranging from less than the paltry GeForce GTX 1650 to roughly RTX 3060 at the top of the stack. Intel plans on launching five discrete GPUs for mobile gamers later today, namely the Arc 3 A350M and A370M, Arc 5 A550M, and the Arc 7 A730M and A770M.
Intel has decided to use two dies for its entire mobile GPU line. The G10 (DG2-512EU) powers the A550M, A730M, and the A770M, and the G11 (DG2-128EU) is used for the A350M and the A370M.
The A770M sits at the top of the stack with a total of 32 Xe cores, 32 ray-tracing units, and 16GB of GDDR6 memory paired with a 256-bit bus. An Xe core packs 16 vector units which in turn incorporate 8 ALUs/shaders each. This results in an overall core count of 4,096 for the A770M. The TDP is a bit on the higher side despite leveraging TSMC’s N6 node.
NVIDIA’s GeForce RTX 3060 mobile which features 3,840 cores and 6GB of GDDR6 memory has a TDP of 115W while the A770M ranges from 120-150W. The A730 with its 24 Xe cores (3,072 shaders) and 12GB of memory scales down the TDP to 80-120W. This comes at the cost of severely reduced core clocks (1,650MHz to 1,100MHz) in addition to fewer EUs (512-384) and a slimmer 192-bit bus.
The midrange Arc 5 A550M comes with 16 Xe cores or 2,048 ALUs paired with 8GB of GDDR6 memory via a 128-bit bus. It boosts to just 900MHz and has a TDP of 60-80W. Finally, the lower-end Arc 3 SKUs come with a paltry 64-bit bus, 4GB of GDDR6 memory, and 6-8 Xe Cores (~1,024 ALUs). These are going to go up against NVIDIA’s GeForce GTX 1650 mobile which has been the company’s most popular GPU over the past few generations.
