Intel ARC Alchemist gaming benchmark graphics cards shown in latest renderings

The earliest renderings of Intel’s ARC Alchemist benchmark graphics cards were featured in the latest Moore’s Law is Dead leak. The renderings show us what Intel’s benchmark design will look like and some information regarding the launch of the desktop ARC line.

Intel ARC Alchemist gaming benchmark graphics cards shown in latest renderings

The benchmark design of the Intel ARC Alchemist graphics card for high-end variants has already been illustrated several times. We saw a prototype leaked by MLID in April 2021, and Intel confirmed the design in its ARC marketing campaign in August. We also recently learned how Intel plans to brand its next line of gaming graphics cards, more on that here.

Moore’s Law is Dead decided to have his friend make a reference graphics card animation based on information he knows from his sources. The resulting render is very detailed and shines a light on almost every aspect of the benchmark graphics card, giving us a detailed look at what could be Intel’s first and very own dedicated design for its first discrete gaming card. Office.

In the renderings, we can see that the card is based on a high-end ARC Alchemist GPU, likely the DG2-512 (Xe-HPG) chip that will power the upper echelon of Alchemist graphics cards. The card comes in a dual slot, dual fan design. Each fan incorporates a 9-blade fan design and there also appears to be RGB built-in around the fans giving a nice touch of blue. The cooler shroud has a circular pattern around the edges which gives a unique touch to the board. There is also the “Intel” logo on the side accent plate which is made of acrylic and also incorporates RGB LEDs. The board rocks a large aluminum finned heat sink and MLID highlights the possibility of a vapor chamber-based cooling solution under the hood.

Apart from these, the board rocks a back plate that extends past the PCB. There are large vents on the back plate through which the second fan can vent air. The board is powered through an 8 + 6 pin connector configuration while the display outputs include a single HDMI port and three DP ports. In the renderings we can only see the outside of the board, so we might have to wait for a PCB render for later. But despite this, Intel’s benchmark and 1st gen ARC Alchemist design looks great and credit to MLID and their friend for providing a first look at the design, once again!

Intel Xe-HPG 512 EU ARC Alchemist Graphics Card

The top variant of the Alchemist 512 EU has only one configuration listed so far which uses the full matrix with 4096 cores, a 256-bit bus interface and up to 16 GB of GDDR6 memory with a clock 16 Gbit / s, although 18 Gbit / s cannot be rumored to be excluded.

The Alchemist 512 EU chip is expected to be around 396mm2, making it larger than the AMD RDNA 2 and NVIDIA Ampere offerings. The Alchemist -512 GPU will ship in the BGA-2660 case which measures 37.5mm x 43mm. NVIDIA’s GA104 Amp is 392mm2, which means the flagship Alchemist chip is comparable in size, while the Navi 22 GPU is 336mm2, which is around 60mm2 smaller. This is not the final die size of the chip, but it should be very close.

NVIDIA packs much larger tensor cores and RT / FP32 cores in its chips, while AMD RDNA 2 chips pack a single spoke accelerator unit per CU and Infinity Cache. Intel will also have dedicated hardware on board its Alchemist GPUs for raytracing and AI supersampling technology.

It is suggested that the Xe-HPG Alchemist 512 EU chip has clocks of around 2.2-2.5 GHz, although we are not sure if these are the average clocks or the maximum boost clocks. Suppose this is the maximum clock speed and in this case the card would provide up to 18.5 FP32 compute TFLOPs which is 40% more than the RX 6700 XT but 9% less than the NVIDIA RTX 3070 .

In a speculative measure of performance, the MLID indicates that TFLOPs make no sense for comparison because performance changes differently depending on the architecture, not the performance of the FLOPs. The gaming graphics card should be roughly faster than the RX 6700 XT and RTX 3070 at this point, but with ongoing work on the driver suite, performance should improve further.

Also, it is reported that Intel’s original TDP target was 225-250W, but has now grown to around 275W. We can also expect a 300W variant with two 8-pin connectors if Intel wants to push its clocks even further. Either way, we can expect the final model to rock with an 8 + 6 pin connector configuration. There is also talk of a custom range that Intel’s AIB partners are working on. The first Intel ARC products will be launched in the first quarter of 2022.
