That could put Alchemist GPU clock speeds upwards of 2GHz, as Xe-LP in discrete form, the Iris Xe Max, is capable of up to 1.65GHz.Īt least there is a possibility for a truly competitive card here, then. Intel has released information regarding the performance/Watt and frequency boost we can expect with Xe-HPG over Xe-LP, at least, and it's looking like a 1.5x gain in both regards. The specs check out, and all appears well in raw bandwidth and compute capability, but building a GPU requires a holistic and universally fine-tuned approach, so well have to wait and see how this one shakes out for the complete picture. Sadly we've very little evidence to prove Intel's proficiency, or lack thereof, today. That's in the right ballpark for what a card reportedly taking aim at Nvidia's GeForce RTX 3070 (opens in new tab), too. So no confirmation on power as of yet but a rough whereabouts of 225-275W. They also suggest a 275W TDP, which is a little greater than previous expectations but still well within the realms of possibility. One hint to the eventual power demands of Alchemist comes from YouTuber Moore's Law is Dead (opens in new tab), who claims to have images of an Intel DG2 card taken during testing, and these clearly show an 8+6-pin power connector setup. Intel has confirmed it will be outsourcing production of Alchemist GPUs to another, TSMC for its 6nm N6 process (opens in new tab). It's not its own, in what might have once been considered a blasphemous statement for Intel's engineers. We've less concrete information in power demand and TGP, but there are some relatively broad assumptions to be made from Intel's choice of foundry and process. Intel is suspected to utilise a 256-bit bus for the top 512 EU graphics card, which will put it on par with Nvidia's RTX 3070 and AMD's Radeon RX 6800, although the latter does benefit from Infinity Cache. That's all information pulled right from Intel's site in the aforementioned leak. Paired with Intel's Xe-HPG GPU is said to be up to 16GB of GDDR6, operating between 14Gbps and 18Gbps. Onwards to memory configuration and it appears as though Intel is keen to match AMD and top Nvidia in raw memory capacity. Up to eight Render Slices combined will make up the top rumoured Alchemist graphics card, which already seems like a mighty amount of silicon to take on AMD and Nvidia at their own game.Įight Render Slices combined will likely make up the top Alchemist GPU, as shown in this diagram. Intel has affixed fixed function units within a Render Slice to support sampler feedback and mesh shading on Alchemist. That's not the only DX12 Ultimate feature on the agenda, either. These units accelerate real-time ray tracing workloads, which Intel has confirmed will be supported with its Alchemist graphics cards. Four Xe-cores combined become a Render Slice, and within each Render Slice resides up to four Ray Tracing Units. Zooming out some, and things get really interesting for this gaming architecture. Intel plans to use these cores for all manner of AI tasks, but namely it's the acceleration of its Xe Super Sampling (XeSS) (opens in new tab) upscaler that has us excited from a gaming point-of-view. Think of them like Intel's version of Nvidia's Tensor Core. These cores deliver acceleration for AI workloads, such as inference tasks for deep learning. You can spot them on the diagram above marked as XMX, which stands for Xe Matrix Extensions-so long as you generously give Intel the 'X' in 'Extensions'. Those Matrix Engines are extremely interesting, too. This is the fundamental Xe-HPG Xe-core layout. ![]() Intel says this was a decision it made to put gaming first for its Alchemist GPUs, and was necessary to build out big gaming graphics cards. The new Xe-core within Alchemist GPUs features 16 Vector Engines and 16 Matrix Engines, which is actually double that found in Xe-HPC. However, the Xe-cores in Xe-HPG are not analogous with what came before, so our best laid plans for possible specifications are just slightly awry. This doesn't entirely change things up, as both Xe-core and EU should share the same essential functionality of grouping together ALUs. The Xe-core is the new fundamental building block for Intel's gaming GPUs (opens in new tab). We had expected a segmentation along the lines of Execution Units (EUs) and memory, although that isn't entirely accurate nowadays as Intel has shifted from the humble EU in favour of the new, all-encompassing Xe-core. Intel Alchemist isn't a single graphics card, it's actually a range of graphics cards.
