Rocket Lake Dicussion Thread

Although Intel never explicitly expressed it, the general expectation was the impending 11th Generation Rocket Lake processors would slot fine into the current LGA1200 motherboard with the 400-series chipset. If there was any doubt, multiple motherboard manufacturers have officially confirmed the processors' backward compatibility.
...
While it's possible to enable Rocket Lake-S processors on all LGA1200 motherboards, we suspect that support will vary from one motherboard vendor to another. Besides the shift to the Cypress Cove microarchitecture, one of Rocket Lake-S's biggest attraction is PCIe 4.0 support. Nonetheless, some vendors might not have initially purposed some of their 400-series offering to support PCIe 4.0, especially the entry-level motherboards. That could be the explanation of why Biostar didn't mention Rocket Lake-S support on non-Z490 motherboards.

The current consensus is that Intel will probably take advantage of CES 2021 to announce Rocket Lake-S, which should come accompanied by new 500-series motherboards. Availability, however, is another story. If one Twitter user's roadmap is genuine, Intel might not commence Rocket Lake-S mass production until January 2021, meaning that the processors won't be hit the retailer shelves until February or even March.

A Bilibili user (via harukaze5719) has posted a thread over at the Bilibili forums that expose the purported specifications of three Intel 11th Generation Rocket Lake-S processors. The chips are engineering samples that the user claims to have picked up on the black market, so final specifications will likely differ from those shown.

The first processor corresponds to the Core i9-11900, which comes equipped with an eight-core, 16-thread configuration and a 16MB L3 cache. The base clock is set at 1.8 GHz, while the single boost clock peaks at 4.5 GHz. The all-core boost on the Core i9-11900 appears to top out at 4 GHz. The Core i9-11900 is a 65W processor, but that's just the PL1 (power level 1) rating. The PL2 value is actually configured to 224W.

Both the Core i7-11700K and Core i7-11700 share the same core specifications as the Core i9-11900. In the case of the Core i7-11700K, the chip reportedly flaunts a 3.4 GHz base clock and a 4.8 GHz single base clock. The all-core boost clock is a bit lower at 4.3 GHz. Coming as no surprise, the Core i7-11700K features a 125W PL1 and a 250W PL2 rating.

According to the Bilibili user, the default XMP frequency for Rocket Lake-S is DDR4-3200. However, it was possible to pair the processors with DDR4-4133 memory on an unspecified B560 motherboard. This is a fascinating discovery as it appears that Intel might have enabled memory overclocking on the B560 chipset. If true, this would be a revolutionary change in the right direction since the chipmaker's lesser chipsets are historically limited to the officially supported memory frequency for that specific generation of processors. For example, existing B460, H470, and H410 motherboards are limited to DDR4-2933 memory modules, which are the Comet Lake-S processors' official specifications.

As spotted by Leakbench, Intel's unreleased Core i7-11700K has been ripped through the Geekbench 5 benchmark tool, and the alleged performance gains over last-gen parts are nothing to scoff at.

Single-core, the chip jots down a score of 1807 points, with a crypto score of 5423 points. Multi-core, it notes down 10,673 points. For comparison, currently, in our test suite, the AMD Ryzen 9 5950X tops the Geekbench 5 Single-core charts with a score of 1713 points, making Intel's Rocket Lake chip about 5.5% faster in single-threaded applications.

But, the catch to note with these scores is that Geekbench 5 uses AVX-512, which makes Intel's scores slightly inflated as only Rocket Lake supports it. Consequently, just because Intel's chip performs 5.5% faster in GeekBench 5, that does not mean it will perform faster than AMD's Zen 3 chips in real-world, single-threaded applications as there are no applications that use this yet -- and this is likely to remain so for quite some time to come.

Because of this AVX-512 discrepancy, it also remains to be seen whether Rocket Lake will catch up with AMD's chips for IPC in real-world use cases.
