Intel Discrete GPU Sneak Peek.
IntelAs Microsoft incorporates new features and capabilities into its DirectX graphics and multi-media API (Application Programming Interface), the company will usually unleash an array of documents and information explaining what the new features do and how to use them. Case in point: Last night Microsoft put up a post on its developer blog outing DirectX Feature Level 12_2. Amidst all of the technical jargon, however, Microsoft also divulged some features that will be supported by partner products from AMD, Intel and Qualcomm – but those products have yet to be released.
DirectX Feature Level 12_2 is a super-set to DirectX 12 with enhanced or newly-enabled support for these main technologies: DirectX ray tracing (Tier 1.1), Mesh shaders (Tier 1), Variable rate shading (Tier 2), and Sampler feedback (Tier 0.9). There’s a lot more coming with Feature set 12_2 as well, but those four are the key capabilities that Microsoft calls out in the post as being the most significant.
DirectX Feature Level 12_2
MicrosoftAlthough the new features in DX12_2 foreshadow future, more efficient and realistic graphics rendering, it was a couple of lines in the FAQ section of the blog post that will really pique the interest of hardware enthusiasts and GPU aficionados...
Q: Which hardware platforms will support feature level 12_2?
A: We’re absolutely pleased to inform that:
- Feature level 12_2 is supported on NVIDIA GeForce RTX and NVIDIA Quadro RTX GPUs.
- AMD’s upcoming RDNA 2 architecture based GPUs will include full feature level 12_2 support.
- Intel’s roadmap includes discrete GPUs that will empower developers to take full advantage of Feature Level 12_2.
- Microsoft is collaborating with Qualcomm to bring the benefits of DirectX feature level 12_2 to Snapdragon platforms.
NVIDIA blazed the trail with support for all of the DirectX Feature Level 12_2 technologies with its existing Turing-based lines of GeForce RTX and Quadro RTX GPUs. AMD, Intel and Qualcomm, however, don’t have any products in their current line-ups capable of supporting the complete DirectX Feature Level 12_2 feature set. But thanks to Microsoft, we now know their next-generation GPUs will.
AMD’s RDNA2 architecture is rumored to arrive later this year. We already knew it would have support for hardware accelerated ray tracing, but now we also know all of the other features in 12_2 will be supported as well.
As for Qualcomm, it’s no surprise Microsoft is working closely with the company to bring 12_2 feature support to its GPUs. Qualcomm produces custom chips for the Surface Pro X and it’s likely Microsoft will continue to embrace and update that platform moving forward.
There is some nuance in the disclosure that Intel’s roadmap contains GPUs with support for DirectX 12_2. The first Xe GPU to arrive with be based on the Xe-LP (Low Power) architecture. Xe-LP only has support for VRS Tier 1; DX 12_2 calls for support of VRS Tier 2. If Intel’s got a GPU on its roadmap with VRS Tier 2 support, it’s likely the Xe-HPG GPU mentioned during Architecture Day a couple of weeks back. Xe-HPG will be a higher-end discrete GPU targeting enthusiast gamers, which is slated to arrive sometime in 2021.
