Intel's upcoming tiger Lake mobile processor will be the first product to demonstrate the Xe GPU platform. One leaked OpenCL Geekbench found that the mid-end product, Core i7-1165G7, scored 59845 points, allowing it to compete directly with the best in a field like AMD and NVIDIA.
The core i7-1165g7 score is about 17% higher than the NVIDIA mx350 average. Considering that the mx350 has 2GB of video memory and the G7 has no dedicated memory, this is a very beautiful lead. More importantly, they have the same TDP, about 25W (depending on the configuration) - but it should be noted that the G7 is integrated into a four core eight thread willow Cove CPU.
In the OpenCL benchmark, ryzen 4600u has an average score of 38000 points, 4700u gets 40100 points, 4800u gets 44000 points, even if the leaked score of about 60000 is a result of extraordinary performance, Intel also beat amd here.
However, both the theoretical performance and the OpenCL benchmark are very general results. In the past, even though AMD's hardware performed well in actual tests, Intel often led in these categories. At present, the evidence suggests that Intel will at least be competitive, but it is hard to say which of the three will be the winner.
