Intel Xe HP: Professional GPU delivers double the ampere FP32 output

Intel xe gaming GPU

GPU Intel Xe HP as part of the extensive Architecture Day. This is offered in three solutions. Despite the low clock rates of the early sample, the flagship beats all previously known products in the laboratory by more than a factor of 2.

Officially, Koduri did not speak of Nvidia, but the mention that previous products provide around 20 TFLOPS FP32 performance is clearly a hint at amps. Nvidia’s first solution A100 delivers 19.5 TFLOPS in FP32 applications. With over 42 TFLOPS from a single package, as Intel emphasizes, you exceed the value significantly.

Intel has three basic scaffolds at the start: 

Intel Xe HP with one tile, with two tiles or with four tiles. Intel had already shown this a few weeks ago via Twitter, at that time Koduri already indicated the performance, but probably for INT8: Scarcely a Petaops should reach the solution. For comparison: Nvidia A100 offers 624 teraops of INT8 performance, so the lead there would be significantly lower.

The technical details of the GPU are still sparse. It is a scalable version with the goal of 75 to 300 watts, HBM is set as memory. The benchmark tool in the demonstration read out 2,048 compute units that work at 1,300 MHz.

Intel will only reveal more details in the coming months, because Intel Xe HP will not be released until 2021. However, the first samples are now to be delivered to partners after the tests have been successful in the laboratory.

The link: SG1 is four times as strong as DG1

But not only at the top, but also in the beginning Intel had to report news. SG1 is a solution that ranks above the first discrete GPU DG1, Intel spoke roughly of the factor 4 in performance. DG1 is designed for thin and lightweight notebooks and in the simplest sense the decoupled LP graphics unit from Tiger Lake with its own memory as a discrete GPU. The integrated graphics of Tiger Lake and DG1 use the same driver and should be able to work together - how and in what form Intel has not revealed today. Both solutions, DG1 and SG1, will be released later this year.

Todayus received the information from Intel in advance under NDA as part of Architecture Day 2020. The manufacturer did not influence the reporting, there was no obligation to publish. The only requirement was the earliest possible release date.
