Intel Xe-HPG Graphics Cards With DG2 GPU Rumored To Launch at CES 2022

A popular Chinese hardware account over at Weibo has stated that Intel would be launching its first discrete graphics cards based on the Xe-HPG DG2 GPU architecture at CES 2022. This is the first news on Intel’s Xe-HPG we have heard in months while leaks for NVIDIA and AMD next-gen parts are going crazy.

Intel’s First Discrete Xe-HPG DG2 GPU Powered Gaming Graphics Cards Rumored For Launch at CES 2022

According to the information published, the Weibo account posts that they have received reliable information from their sources on Intel’s first discrete graphics cards which will utilize the Xe-HPG architecture. The DG2 GPUs will make a formal debut in the retail market at CES 2022 which is next January. However, it is very likely that we get a teaser look at the cards around the end of October at the Intel Innovation event.

Intel has already stated that Xe-HPG Gaming GPU prototypes are being sampled now and we have already seen a couple of chips appear in online benchmark databases including a 256 EU part that could be a variant of the flagship DG2-512 or the DG-384 SKUs. There have also been leaks of 448 EU &128 EU SKUs which you can read about over here. The performance currently is quite under-whelming due to unoptimized drivers, poor clock speeds on prototypes, and severely limited GPU capabilities but those will improve once we reach ES/QS states.

Here’s Everything We Know About Intel Xe-HPG DG2 Gaming GPU Lineup

Each Xe-HPG based DG2 GPU SKU will come in various configurations which will range from the full-fat chip to several cut-down variants. This is similar to NVIDIA’s Ampere GA102-400, GA102-200 naming schemes, or AMD’s Navi 21 XTX, Navi 21 XT, Navi 21 XL naming conventions.

Intel Xe-HPG DG2 512 EU Discrete Gaming Graphics Cards

Intel Launches Xeon W-3300 Ice Lake Workstation CPUs: Up To 38 Cores, 4.0 GHz Clocks, 270W TDP, Starting at $949 US

The top DG2 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 (8 GB GDDR6 listed too). Based on demand and yields, Intel could produce more variants of this flagship chip but we can’t say for sure right now.

The DG512 EU chip is expected to measure at around 396mm2 which makes it bigger than the AMD RDNA 2 and NVIDIA Ampere offerings. The DG2-512 GPU will come in the BGA-2660 package which measures 37.5mm x 43mm. NVIDIA’s Ampere GA104 measures 392mm2 which means that the DG2 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 is expected to have hardware-accelerated ray-tracing capabilities onboard its Xe-HPG GPUs & a recent tweet from Raja also seems to point out hardware DL/ML capabilities that would assist in supersampling tech.

The Xe-HPG DG2 512 EU chip is suggested to feature clocks of up to 2.2 GHz though we don’t know if these are the average clocks or the maximum boost clocks. 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. We have also already seen leaked PCB and pictures of an ES Xe-HPG DG2 based graphics card which you can see here.

Intel Xe-HPG DG2 384 EU Discrete Gaming Graphics Cards

Moving on, we have the Intel Xe-HPG DG2 384 GPU SKU which is expected to comprise at least three variants. The full fat chip will feature 3072 cores, up to 12 GB GDDR6 memory (6 GB GDDR6 listed too), and a 192-bit bus interface. Then we have two variants, a 256 EU and a 192 EU variant which are comprised of 2048 and 1536 cores. While both variants feature a 128-bit bus interface, the 256 EU SKU will come with up to 8 GB GDDR6 memory (4 GB GDDR6 listed too) while the 192 EU variant will stick with just 4 GB GDDR6 memory. Based on the specifications, these GPUs will be positioned as mainstream parts.

Videocardz had earlier leaked out the die configuration of the Intel Xe-HPG DG2 384 GPU variant which should measure 190mm2. The PCB blueprint shows 6 memory module locations which do confirm a 192-bit bus interface and either 6 or 12 GB GDDR6 memory capacity. The 384 and 256 EU SKUs are expected to feature 16 MB and 8 MB smart cache, respectively. The clock speeds for the 384 EU parts are reported at 600 MHz base and 1800 MHz turbo while the 256 EU part will feature a 450 MHz base and 1400 MHz turbo clock.

Intel Xe-HPG DG2 128  EU Discrete Gaming Graphics Cards

Then lastly, we have the Intel Xe-HPG DG2 128 EU parts. The top config is once again a full-fat SKU with 1024 cores, a 64-bit bus interface, and 4 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. This GPU will be very similar to the DG1 GPU-based discrete SDV board however DG2 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.

We have seen the Intel Xe-HPG DG2 GPU-based discrete graphics card engineering sample leak out last month along with some rumored performance and pricing figures, you can read more on that here. Based on the timeline, the Xe-HPG DG2 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. The Xe-HPG GPUs will be coming to the mobility platform too and will be featured in Alder Lake-P notebooks.

Where are you expecting the Intel Xe GPUs to land within the desktop discrete graphics card landscape?
