TUM_APISAK has shared some figures that demonstrate how two of Intel’s upcoming Xe-HPG DG2 gaming GPUs might fare against the competition. According to the leaker, Intel’s second-best DG2 GPU—a newly discovered SKU featuring 448 Execution Units and a boost clock of 1.8 GHz—will come quite close to NVIDIA’s GeForce RTX 3070 graphics cards in terms of performance. This particular GPU is also said to be 8 percent slower than AMD’s Radeon RX 6700 XT. Another of Intel’s DG2 GPUs, which only features 128 Execution Units but a boost clock of 1.9 GHz, is estimated to be 12 percent faster than NVIDIA’s GeForce GTX 1650.

[…] the Intel Xe-HPG DG2-448 EU SKU tested was operating at a clock speed of around 1.8 GHz while the 128 EU SKU was operating at a clock speed of around 1.9 GHz. We don’t know if that’s the average, max, or base clock speed but given what we have seen on the Xe architecture, it should be the maximum clock speed.
