Intel Rocket Lake Desktop CPUs Will Launch in March, Gigabyte Confirms - ExtremeTech:

Gigabyte has confirmed that Intel will launch its Rocket Lake CPU refresh in March, as part of an announcement touting its own PCIe 4.0 support. Gigabyte announced today that if you own a Z490 motherboard, you'll be getting a UEFI update to support Rocket Lake CPUs with full PCIe 4.0 support.

The rest of the PR goes into detail on how Gigabyte engineered their motherboards to handle the higher heat output of PCIe 4.0, and the fact that addressable BAR support is coming to the company's motherboards as well. Addressable BAR is the same feature AMD debuted as Smart Access Memory earlier this year.

The March 2021 date confirms what we've heard previously — late March is more likely than early March. It's going to be genuinely interesting to see how Cypress Cove performs against AMD's Zen 3. Generally speaking, based on leaked benchmarks and early data, we're looking at impressive gains for Intel in single-thread performance. Multi-thread performance estimates for the Core i9-11900K have varied. In some cases, the 11900K is almost a match for the 10-core Core i9-10900K. In a few leaked results, it's actually been faster on eight cores than Comet Lake was on 10.

Are any of my fellow Soylentils doing PC builds right now, and if so what are you building? Let us know in the comments!

It also adds AVX-512 and "Deep Learning Boost" support. The integrated graphics should be about 50% faster, and can be used for stream encoding while discrete graphics is being used for gaming. AV1 video decode is supported. New Z590, B560, and H510 motherboards will support both Rocket Lake and Comet Lake. Intel's comparison of the 8-core i9-11900K to AMD's 12-core Ryzen 9 5900X shows the former performing 2-8% faster at several games at 1080p.

    You've not looked at enough cases, then. https://www.newegg.com/white-in-win-a1-plus-mini-itx-tower/p/2AM-001H-001M2 [newegg.com]

    Though, there is this kind of thing too: https://www.newegg.com/asrock-deskmini-x300w/p/N82E16856158068 [newegg.com] (Tiny, all metal, about the size of a regular PSU.) Limited to APUs, but could stick one of these in it: https://www.newegg.com/p/1FR-0001-000N0 [newegg.com] (Ryzen 7 PRO 4750g, capable of playing fairly recent games on low to medium settings at 1080p.) For under $1k should be able to put together a very nice, very tiny computer. Just don't expect it to be a serious gaming machine. It might be okay for some VR games, but I'd guess the experience would leave something to be desired.

    I'm not in the market for a while, so I don't really look at a lot of cases. But what I do notice is a lot of tempered glass, especially on full towers.

    There are rumors that AMD will start including graphics across the whole desktop CPU lineup (which would make them all APUs, but chiplet-based instead of monolithic with lower core counts like Renoir 4750G). For example, Zen 4 + RDNA 3. I think the decision to not include graphics on the original Zen CPUs was so that AMD could focus on CPU performance and core counts while keeping costs low. Today, the chiplet approach offers some flexibility, CPU and graphics cores will be tiny on TSMC's "5nm" node, and there is a need for an iGPU that can also be used for machine learning acceleration (every new pre-built system will be advertised as having this capability in the near future).

    I would rather get something that can fit a graphics card (maybe low profile), but aim for the case to be smaller. I might even get a standard ATX motherboard, depending on the memory situation.

    VR gaming will not be much less demanding in the long run, unless foveated rendering lowers the performance needed dramatically. VR gaming will be a major driver of resolution and frame rates. 8K gaming is a meme unless you strap it to your face.
