DG2-512 16 GB GPU To Tackle RTX 3070 Ti & DG2-384 12 GB Tackles RTX 3060 Ti

As we get closer to CES 2022, we are hearing more and more rumors regarding Intel’s ARC Alchemist gaming graphics card lineup based on the Xe-HPG DG2 GPUs.

Intel’s ARC Alchemist High-End Graphics Lineup Rumored For March Launch, Will Include DG2-512 16GB & DG2-384 12 GB Variants

As per the latest rumors from Expreview forums (via ITHome), it is reported that Intel had initially planned to launch its ARC Alchemist graphics lineup in January 2022 but that was postponed to the very end of Q1 and may possibly even slip to Q2 but that remains to be seen as Intel might have changed its plans and moved the launch ahead. The first ARC Alchemist DG2 GPUs have already been shipped to major AIB partners for debugging so we can expect a range of custom cards to be available at launch along with the reference models.

As for the lineup itself, it is said that aside from the entry-level ARC A380 which features the DG2-128 GPU (SOC 2), Intel will have two ARC Alchemist graphics cards based on the DG2-512 SKU (SOC 1). As for the configurations for each Intel ARC Alchemist GPU, they are mentioned below in full detail:

The top Alchemist 512 EU (32 Xe Cores) variant is said to feature at least three configurations. The full die features 4096 cores, a 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. Following are all the ARC 512 EU variants that we can expect based on the DG2-SOC1:

  • 512 EU (4096 ALUs) / 16 GB @ Up To 18 Gbps / 256-bit / 225W (Desktops) & 120-150W (Laptops)
  • 384 EU (3072 ALUs) / 12 GB @ Up To 16 Gbps / 192-bit / 150-200W (Desktops) & 80-120W (Laptops)
  • 256 EU (2048 ALUs) / 8 GB @ Up To 16 Gbps / 128-bit / 60-80W (Laptops)

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.

In terms of performance positioning, the top 512 EU variant is said to compete against the RTX 3070 / RTX 3070 Ti, the 384 EU variant is said to compete against the RTX 3060 / RTX 3060 Ti on desktops. On the laptop side, the 512 EU might be just as fast as the RTX 3080, 384 EU variant around RTX 3070 level and the 256 EU will end up against the RTX 3060.

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.

As for the launch, the SOC1 variants are planned for launch in Mid-February & while AIBs are waiting on final dies to test with their custom PCB designs, desktop variants may be launching first, followed by laptop and then workstation in late 2022.

Then lastly, we have the Intel Xe-HPG Alchemist 128 EU (8 Xe Cores) parts. There are two configs that feature the full-fat SKU with 1024 cores, a 96-bit, and a 64-bit variant with 6 GB and 4 GB memory capacity, respectively.

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.

Following are all the ARC 128 EU variants that we can expect based on the DG2-SOC2:

  • 128 EU (1024 ALUs) / 6 GB @ Up To 16 Gbps / 96-bit / ~75W (Desktops)
  • 128 EU (1024 ALUs) / 4 GB @ Up To 16 Gbps / 64-bit / 35-30W (Laptops)
  • 96 EU (768 ALUs) / 4 GB @ Up To 16 Gbps / 64-bit / ~35W (Laptops)

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.

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. By 2023, Intel will have a proper high-end graphics card lineup going up against NVIDIA’s Ada Lovelace and AMD RDNA 3 chips in the form of ARC Battlemage.
