Leaked benchmark of Intel Arc Alchemist discrete desktop GPU shows RTX 3070 Ti performance

Intel Xe-HPG card with 512 Execution Units and 2.1 GHz clock spotted

A benchmark new entry featuring Intel’s highly anticipated Arc Alchemist card has been spotted over at the SiSoftware website

According to this result, which was first spotted by TUM_APISAK, the card features the full 4096 core count of the Intel DG2-512EU silicon. This card was tested on a desktop Coffee Lake-S platform, which suggests this is indeed a discrete desktop graphics card.

The data shows it comes with a 2.1 GHz clock speed, which could be either the base clock or boost clock, depending on how this architecture operates in such benchmarks. Furthermore, the card is listed with 12.8 GB of memory, which is probably just an error showing a partially allocated 16GB frame buffer. After all, this Arc Alchemist flagship was always expected to feature 16 GB GDDR6 memory across 256-bit memory.

Things get a little bit more interesting when looking at the performance of GPU’s General Purpose Processing data. The card actually scored higher than NVIDIA’s RTX 3070 Ti GPU. With a score of 9017.52 Mpix/s, it is 7.7% faster than the NVIDIA card which only scored 8369.51 Mpix/s.

Both cards are trading places in different precision tests, for instance, Arc Alchemist appears to be faster in half-float, double-float, and quad-float tests, but it loses in the single-float test.

This model, which has not yet been named, will be available as mobile and desktop SKU. Rumors suggest it might clock up to 2.5 GHz and feature around 225W of typical power. It was speculated to compete against RTX 3070 graphics with a chance of reaching RTX 3070 Ti performance. NVIDIA knows this very well, which is why the company has been preparing an updated RTX 3070 Ti model with 16GB memory to match the new competitor.

The card has already been pictured and leaked by a YouTuber Moore’s Law is Dead. He was among the first to claim it might be able to compete with NVIDIA RTX 3070 series.

Intel Arc Alchemist will officially become available this quarter, but we might need to wait a bit more for the desktop series launch because Intel has thus far only shown mobile OEM systems with Arc.
