Rocket Lake Dicussion Thread

In conjunction with Intel’s Rocket Lake CPU announcements, board partners pulled back the curtain on several new Z590-based motherboards to go along with the upcoming chip. The new motherboards promise native PCIe 4.0 support (with Rocket Lake CPUs), USB 3.2 Gen2x2 support from the chipset and upgraded power delivery. Best of all, we’ll get to see some new board designs. All of the major board partners have released a slate of options based on the new chipset -- many of which we’ll eventually review -- and a select few may even make it to our best motherboards page.

At the time of this writing, Intel has not released the full details of the Z590 chipset. However, we do know a few things that differentiate Z590 from the previous-gen Z490. Unlike Z390 to Z490, the LGA 1200 socket remains the same, which in this case means both Rocket Lake-S and Comet Lake-S chips will work with Z590 based motherboards; Z490 requires a BIOS update to work with Rocket Lake processors. In addition to the flagship Z590 chipset, Intel is also releasing B560 and H510 chipsets. Typically these lesser chipsets are locked to prevent overclocking. However, there are rumors of B560 overclocking. Stay tuned on that front.

The most significant difference between the two chipsets is native PCIe 4.0 support when using a Rocket Lake processor. A Rocket Lake CPU shares 20 PCIe PCIe 4.0 lanes between the PCIe slots/GPU and M.2 socket/storage. It feels like Intel has finally caught up to AMD’s B550 chipset, at least, but still isn’t close to the lane count and flexibility of X570.

Another significant difference with Z590 is the DMI link between the chipset and CPU. On Z590, Intel has doubled the link speed, going from PCIe 3.0 x4 to x8. The jump to x8 effectively doubles the amount of bandwidth available for any chipset-connected devices (storage and networking for example). Additionally, the chipset now has native support for USB 3.2 Gen 2x2 (20 Gbps), so we should see these ultra-fast USB Type-A and Type-C ports on most Z590 motherboards.
...
Memory support for the new CPUs also gets a small bump from DDR4 2933 to DDR4 3200 when using the new Rocket Lake-based processors. The new value now matches AMD’s official maximum for memory support. Some of the new boards support overclocked DDR4 to speeds well over 5000 MHz - similar to what we saw with Z490. As usual, your mileage will vary, and working with the correct CPU (with a good integrated memory controller) and memory kit is critical when chasing high memory clocks. That said, the sweet spot for memory speeds and performance per dollar is likely around where it currently is, DDR4 3600-3800 with CL14/16. Much beyond that and the kits’ price goes up sharply while performance doesn’t follow linearly.
...
While Z590 has arrived, we still awhile to wait to see how the new CPUs fare, which is rather unfortunate. At some later point, lower-priced B560 and H510 chipset-based motherboards will be available. But at the time of this writing, there are over 45 Z590 boards to choose from. So if you’re looking to build a new system based on Intel’s latest, there should be something for everyone.

Intel is betting big on an 8-core processor to revive its gaming performance leadership, and that chip is the 11th Generation Core "Rocket Lake-S," coming this March. In its 2021 International CES online event, Intel disclosed more details about "Rocket Lake-S," including the first true-color die-shot. PC enthusiast @Locuza_ on Twitter annotated the die for your viewing pressure. For starters, nearly half the die-area of the "Rocket Lake-S" is taken up by the uncore and iGPU, with the rest going to the eight "Cypress Cove" CPU cores.

The third major component is the uncore, which looks visibly larger than the one on the 8-core "Coffee Lake Refresh" silicon. This is because it features a PCI-Express Gen 4.0 switching fabric, and additional SerDes to put out 28 PCIe lanes, compared to just 20 on the older generation. We imagine the memory controllers are largely unchanged, as Intel is sticking with dual-channel DDR4 as the memory standard for "Rocket Lake-S." The switch to DDR5 could probably herald a new socket, with "Alder Lake-S."
