To compete head-on with AMD and NVIDIA, Intel's arc alchemist has a long way to go. After measuring the Intel Xe LP based DG1 graphics card for a period of time, twitter user L ö schzwerg found an error related to the throughput of PCIe 4.0 In the PCI Express function test of 3dmark, gunnir index V2 DG1 failed to saturate the PCIe 4.0 channel
Index V2 seems to work well on all previous PCIe interfaces. However, on PCIe 4.0, the performance of the card is the same as that of PCIe 3.0, although it should get about twice the score. This indicates that DG1 has some form of bottleneck or error.
Next is arc alchemist based on Xe HPG architecture, which is the successor of Xe LP. The first evaluation of arc a350m also shows that Intel's dynamic tuning technology (DTT), a function similar to AMD's smartshift technology, is damaging the performance of arc GPU. When DTT is turned off, the frame rate is almost doubled, as can be seen from the picture below.
Intel should be easy to solve because it may only need some optimization of the power state (P state). At the same time, it may be difficult to fix PCIe errors, because this problem is generally not so common in AMD radeon or NVIDIA geforce GPU.
