Intel Arc Alchemist with 512 EUs suffers from low GPU clock in Geekbench OpenCL benchmarks

Intel Arc Alchemist flagship desktop GPU with 512 Execution Units shows up on the Geekbench website

This is likely not to be the full-fledged performance of the flagship Arc Alchemist GPU, neither the graphics driver is final nor the clock speed reported by the benchmarking software is close to the maximum clock.

According to detailed JSON data from four benchmark runs, a GPU described as “OpenCL HD Graphics” or “Intel Xe Graphics” featuring as many as 512 Execution Units and 12.7 GB of memory, has been operating at 1329 MHz frequency, just 63% of the maximum frequency of 2.1 GHz.The Arc Alchemist GPUs based on TSMC N6 node are more than likely to operate at much higher frequencies, possibly similar to AMD RDNA2 GPUs which are typically higher than 2 GHz.

The GPUs have tested an Intel Coffee Lake desktop validation platform featuring a Core i5-9600K 6-core processor. The fact that the tests were performed using a validation platform tells us that Arc Alchemist GPUs are still far from launch. In comparison to Intel 12th Gen Core Alder Lake-P mobile processor series which launched in January, we can already find leaks featuring actual retail products (upcoming laptops).

In four of the benchmark runs, the GPU scored 69220, 68418, 6603, and 64964 points, which according to Geekbench’s own performance charts, is close to GeForce RTX 2060 desktop GPU and slightly above Pascal-based NVIDIA Titan Xp. The 512EU model of Arc Alchemist GPU is to feature 16GB GDDR6 memory, so the 12.7 GB capacity reported by Geekench is likely incorrect.
