Over at VideoCardz, they’ve posted some information on the forthcoming Intel 500 series of chipsets for the Rocket Lake-S platform. We have logos for the Z590, B560, and H510. They also have a slide outlining some key details of the 500 series. To start things off, 4 new PCIe lanes have been added to the CPU, upping the count to 20 similar to Zen 3. We also, finally, have an update to PCIe 4.0 for these 20 CPU lanes, allowing for support of PCIe 4 M.2 storage devices, as well as a direct PCIe 4.0 x16 GPU connection.
The DMI bus between the CPU and the chipset is now x8, doubling the bandwidth available currently to 64Gb/s each way. The 500 series chipsets themselves support additional PCIe lanes, as you’d expect, but they’re still limited to PCIe 3.0. That’ll do the job, but it’s a hit against the platform vs the full PCIe 4.0 support of the the AMD X570. Some other information notes increased DDR4 speeds. One would assume this means DDR4-3200, but time will tell. As will the “new overclocking features”. Head on over to read more.
