But we’ll see the continued use of formidable VRMs and large heatsinks to keep these power-hungry CPUs in check. With fewer cores and threads to cool, perhaps thermal mitigation will be less of an issue on the new CPUs. We know it will have a TDP/PL1 of 125W with a PL2 (turbo) power limit of 250W, with a 56-second duration. Intel hasn’t shared too many details on the Rocket Lake CPU, including TDP. Intel Z590, Z490 and Z390 Chipset Comparison Feature 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. A Rocket Lake CPU shares 20 PCIe PCIe 4.0 lanes between the PCIe slots/GPU and M.2 socket/storage. The most significant difference between the two chipsets is native PCIe 4.0 support when using a Rocket Lake processor. However, there are rumors of B560 overclocking. Typically these lesser chipsets are locked to prevent overclocking. In addition to the flagship Z590 chipset, Intel is also releasing B560 and H510 chipsets. 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. However, we do know a few things that differentiate Z590 from the previous-gen Z490. Intel Z590 Chipset: Same Socket, Different FeaturesĪt the time of this writing, Intel has not released the full details of the Z590 chipset. Until then, we have some high-level information about the new Z590 chipset and the motherboards that go along with it to tide you over. When the time comes, we’ll have a full CPU review as well as an updated product list. As with previous launches, Intel will certainly fill out the product stack with other variants such as 6-core/12-thread processors down to 4-core/8-thread parts. Helping to make up for the core count deficit, the new CPU architecture is supposed to bring significant IPC improvements as well as AVX-512 support, faster base memory speed (up to 3200 MHz), 20 CPU-connected PCIe 4.0 lanes, Intel Xe integrated graphics and more. And if your work needs more, you can step up to the HEDT platform or buy an AMD Ryzen 5000 series/X570 combination. At this time, there aren’t many (possibly any) games that show a marked performance improvement above an 8-core/16-thread setup. But the reality is, that change won’t affect a lot of users. On the CPU front, the Rocket Lake CPUs took a step backward on core count at the top end, with the flagship Core i9-11900K set at 8-core/16-threads (like the i9-9900K had in 2018), while the Core i9-10900K was a 10-core/20-thread part.
