Intel’s ARC Alchemist graphics cards pictures which include high-end and entry-level Xe-HPG GPU-based models have been leaked by Moore’s Law is Dead. The high-end graphics card in particular being the most interesting of the two since we also get a glimpse of its PCB in close to final form.
Intel ARC Alchemist Graphics Cards Pictured, Include High-End & Entry-Level Xe-HPG GPU Designs
MLID had already shared the first PCB shots of the ARC Alchemist high-end graphics card back when it was still in the early engineering phase. Earlier this month, he also shared new renders, showcasing the high-end ARC Alchemist shroud design in detail. Now, MLID has leaked out both, the high-end and finalized design for the Intel ARC Alchemist high-end graphics card featuring up to 32 Xe Cores and also renders of the entry-level part with up to 8 Xe Cores.

Starting with the design, the high-end graphics card features a design similar to the one we saw in the renders but now it looks more polished with reflective silver colors and two 9-blade fans that feature the proper Intel logos. The PCB has seen a major change since the last time we saw it in its prototype stage. Since this is close to its final design, the PCB color has been upgraded to black and the size itself has gotten shorter. The power connectors are no longer on the back but on the sides of the card and the high-end variant utilizes an 8+6 pin configuration for a maximum power draw of 300W. The second fan mostly blows air through the aluminum heatsink as it extends beyond the PCB. There should also be a backplate on the card but that has not been shown in these pictures.

The entry-level Intel ARC Alchemist graphics card reminds me of the Xe-LP SDV. The rendered design is said to be based on the real thing which MLID can’t show right now. The card features a compact design with a dual-slot form factor and may feature a single 6-pin connector to boot. The card offers four display outputs (3 DP + 1 HDMI). MLID also states that AIBs are desperate for a low-end graphics card solution to tackle the likes of the GeForce GTX 16 series which are expensive and the supply issues have made pricing even worse. With an entry-level ARC Alchemist graphics card, it might just have the potential to disrupt the low-end desktop GPU segment.
Intel Xe-HPG 512 EU ARC Alchemist Graphics Card
The top Alchemist 512 EU variant has just one configuration listed so far and that utilizes the full die with 4096 cores, 256-bit bus interface, and up to 16 GB GDDR6 memory featuring a 16 Gbps clock though 18 Gbps cannot be ruled out as per the rumor.
The Alchemist 512 EU chip is expected to measure at around 396mm2 which makes it bigger than the AMD RDNA 2 and NVIDIA Ampere offerings. The Alchemist -512 GPU will come in the BGA-2660 package which measures 37.5mm x 43mm. NVIDIA’s Ampere GA104 measures 392mm2 which means that the flagship Alchemist chip is comparable in size while the Navi 22 GPU measures 336mm2 or around 60mm2 less. This isn’t the final die size of the chip but it should be very close.
NVIDIA packs in tensor cores and much bigger RT/FP32 cores in its chips while AMD RDNA 2 chips pack a single ray accelerator unit per CU and Infinity Cache. Intel will also have dedicated hardware onboard its Alchemist GPUs for Raytracing & AI-assisted super-sampling tech.
The Xe-HPG Alchemist 512 EU chip is suggested to feature clocks of around 2.2 – 2.5 GHz though we don’t know if these are the average clocks or the maximum boost clocks. Let’s assume that it’s the max clock speed and in that case, the card would deliver up to 18.5 TFLOPs FP32 compute which is 40% more than the RX 6700 XT but 9% lower than the NVIDIA RTX 3070.
Also, it is stated that Intel’s initial TDP target was 225-250W but that’s been upped to around 275W now. We can expect a 300W variant with dual 8-pin connectors too if Intel wants to push its clocks even further. In either case, we can expect the final model to rock an 8+6 pin connector config, The reference model is also going to look very much like the drone marketing shot Intel put out during the ARC branding reveal. That reference design was leaked a while back by MLID too. There’re also talks about a custom lineup being worked upon by Intel’s AIB partners.

Intel Xe-HPG 128 EU ARC Alchemist Graphics Card
Then lastly, we have the Intel Xe-HPG Alchemist 128 EU parts. The top config is once again a full-fat SKU with 1024 cores, a 64-bit bus interface, and up to 8 GB GDDR6 memory. The cut-down variant will come with 96 EUs or 768 cores and a 4 GB GDDR6 memory featured across a 64-bit bus interface. The chip will also feature a clock speed of around 2.2 – 2.5 GHz and have a sub 75W power consumption which means we will be looking at connector-less graphics cards for the entry-level segment.
Performance is expected to land between the GeForce GTX 1650 and GTX 1650 SUPER but with raytracing capabilities. One big advantage that Intel could have over AMD and Intel is that with these cards, they might enter the sub-$250 US market which has been completely abandoned in the current generation of cards. The GeForce RTX 3050 series only got a laptop release so far with RTX 3060 serving the entry-level Ampere segment at $329 US while the RX 6600 is expected to be AMD’s entry-level solution for around $300 US.
This GPU will be very similar to the DG1 GPU-based discrete SDV board however Alchemist will have a more improved architecture design and definitely more performance uplift over the first-gen Xe GPU architecture. This lineup is definitely going to be aimed at the entry-level desktop discrete market based on the specifications.

| Xe-HPG 96EU | ARC A*** | Alchemist-128EU | 86 EUs | 768 | 8/6/4 GB GDDR6 | 96/64-bit | 50-75W? |
Based on the timeline, the Xe-HPG Alchemist lineup will compete against NVIDIA’s Ampere & AMD RDNA 2 GPUs since both companies aren’t expected to launch their next-gen parts by the very end of 2022. NVIDIA and AMD are expected to release refreshes in early 2022 so that might give Intel’s new lineup some competition but based on current performance expectations, the refreshed may not bring drastic performance differences to the lineup. The Xe-HPG ARC GPUs will also be coming to the mobility platform too and will be featured in Alder Lake-P notebooks.
