Intel 11th Generation Rocket Lake-S Desktops CPUs Are Finally Here


Intel has lifted the veil from its 11th generation Rocket Lake-S desktop CPU series, thus finally making the lineup official. As we have come to expect of such a launch, the chipmaker’s new processor range is abundant with features, both new and long-awaited.

As per initial reports, Intel’s 11th generation Core S series CPUs not only come with per-core IPC improvements but the entire lineup finally supports the latest PCIe 4.0 interface. On top of that, it’s top-of-the-line CPU will support up to 20 PCIe 4.0 lanes. And before you ask: yes, the new CPUs will be the last of Intel 14nm process node, but as we’ve mentioned many times before, the architecture has been backported from Intel’s 10nm process node.

Also, as promised, the new CPU lineup also supports resizable BAR, meaning that these processors will be able to draw upon a GPU’s entire memory capacity, in order to squeeze out a little more performance from the system, be it for gaming or slightly more professional workloads. Other features include support for DDR4-3200 RAM support, Intel Deep Learning Boost and VNNI Support, plus new integrated graphics based on the brand’s new Xe graphics architecture.

Of course, no CPU is complete with a motherboard and as with all new CPU lineup, the new 11th generation lineup is also accompanied by a new 500 series chipset that also comes with new and improved features on the platform. Off the bat, new 500 series motherboards – the high-end models especially – will support USB 3.2 Gen2x2 for transfer speeds of up to 20Gbps, support for up to 20 PCIe 4.0 lanes with all Rocket Lake-S CPUs, Discrete Wi-Fi 6e and support for Intel Thunderbolt 4.

Perhaps the most important feature to be added by Intel to the 500 series chipset, however, is the ability to overclock memory on both the mid-range H570 and entry-level B560 chipsets. Speaking of overclocking, Intel says that it is also bringing new overclocking improvements to 11th gen.

Besides memory overclocking on non-Z500 series motherboards, the chipmaker is also introducing real-time memory overclocking, as well as AVX2 and AVX-512 Offset and Voltage Guard-Band Override. The last one being of increased interest as the feature would undoubtedly increase the overall performance of a system built around the new 11th generation CPU and 500 series chipset.

As for CPU models, the new 11th generation Core series follows the same Intel hierarchy and nomenclature. To name a few and sitting on the pedestal is the Core i9-11900K, Intel’s high-performing 8-cores, 16-threads processor, with a base clock of 3.5GHz and an all-core boost clock of 5.3GHz.

Thanks to Intel’s Thermal Velocity Boost (TVB) technology. Moving down a notch is the Core i7-11700K, which has the same number of cores as the 11900K, and a base clock of 3.6GHz. Unfortunately and as you can see from the SKU list, Intel is being coy about the 11700K’s boost clock with TVB enabled.

On a related note, Intel announced a list of refreshed 10th generation Intel Core series CPUs that will work with its 500 series chipset, although we should point out that this is only applicable to the lower-tier Core i3 CPUs and Pentium Gold G Series CPUs. It’s a bit of an odd decision and frankly, we’ve been wondering why Intel didn’t just refresh some of its beefier 10th generation Core i5 and Core i7 processors while they were at it.

The only thing missing from Intel’s announcement, though, is availability. At the time writing, the chipmaker didn’t say when its new processors and 500 series motherboards will be hitting the store shelves of PC stores, but at this stage, it’s very likely to be sooner than later. That is, assuming Intel itself hasn’t found itself a victim of the ongoing chip shortage too.
