In excess of the previous number of weeks, chatter has enhanced about Rocket Lake’s effectiveness and corresponding benchmark leaks. We have witnessed a amount of Geekbench effects for numerous CPUs and penned a few comparisons ourselves. Due to the fact the leaks continue to keep coming, it appeared more handy to spherical up expectations for RKL and how it’ll very likely evaluate to Zen 3 / Ryzen 5000, rather than continue dissecting just about every leak individually. We’re evaluating CPUs right here alternatively than platforms, but Rocket Lake also introduces options like PCIe 4. for Intel CPUs.

Rocket Lake takes advantage of Intel’s Cypress Cove CPU architecture. Cypress Cove is a backport of Intel’s 2019 Ice Lake architecture, designed on the company’s older 14nm process. Intel has ongoing applying 14nm for desktops, in spite of owning 10nm in-sector for cellular, because the properties of the node have been improved suited to developing significant-general performance multi-core CPUs. Cypress Cove is expected to offer you ~1.19x greater IPCs than Comet Lake, and it provides AVX-512 aid to buyer devices. But how will this basically evaluate in opposition to AMD?

To start with, we count on Rocket Lake to deliver sturdy solitary-thread functionality advancements. Ever since AMD introduced Ryzen, Intel has emphasised superior single-threaded efficiency. AMD claimed the gaming sector with the launch of the Ryzen 5000 series, but Rocket Lake delivers Intel a probability to seize it again once again. Several leaked outcomes propose Rocket Lake’s single-threaded overall performance is someplace among 1.17x – 1.35x faster than the equivalent Comet Lake processor. Both would depict respectable generational uplift.

Intel’s Main i9-11900K announcement slide from CES previously this yr.

Intel will be at its strongest versus AMD in reasonably threaded programs that really do not scale effectively above eight cores. The expected IPC gain is superior plenty of to give Intel a serious shot at recapturing gaming total.

Rocket Lake’s multi-threaded efficiency is a minimal more difficult to forecast. The same leaks that counsel major single-threaded leaps occasionally predict more compact multi-threaded enhancements of 1.1x – 1.25x depending on the software and the CPU. Some leaked success use engineering samples, not retail chips, and a huge established of benefits is not unconventional. The most constructive leaks advise that the Core i9-11900K will match or somewhat exceed the Main i9-10900K’s overall performance, even however it only fields eight cores to its predecessors’ 10. The significantly less flattering predictions counsel the Core i9-11900K will come in just powering the 10900K. We’re probable to see the two these effects in practice, based on the diploma to which an software is or isn’t fond of Intel’s Cypress Cove architecture.

We really do not assume extraordinary improvements in electricity use, considering that Intel is nonetheless functioning with the exact 14nm node. We expect any electrical power effectiveness advancements Rocket Lake delivers to get there courtesy of enhanced IPC as opposed to intrinsically reduce transistor-degree electricity consumption. If Intel has managed to improve IPC and complete electricity consumption, so a great deal the greater.

Rocket Lake isn’t going to defeat AMD’s whole item stack. CPUs like the 5900X and 5950X will keep on being complete efficiency leaders in perfectly-threaded apps. But Intel isn’t hoping to exhibit that its eight-core chip can defeat a 16-main CPU. Rocket Lake is meant to demonstrate that Intel can however shift the desktop forward and increase IPC, although ideally winning again specific segments like gaming. Again in 2018, Intel informed the assembled press it was operating on a new method-agnostic structure methodology that would let it to shift CPUs among nodes a great deal more very easily than right before. Rocket Lake is a phase towards that overall flexibility.

Total, we count on Rocket Lake to severely obstacle AMD on solitary-threaded general performance, notably in gaming. In multi-threaded, we be expecting the Core i9-11900K to match or a little exceed the 5800X. AMD’s Ryzen 9 5900X and Ryzen 9 5950X will outpace Rocket Lake in any multi-threaded functionality comparison, but which is to be expected. Performance for every watt is likely to favor AMD. General performance for every greenback will rely on how Intel rates its CPUs. If Intel costs aggressively, it may well be equipped to pull off an upset from AMD at many rate details. If it sticks to its typical habits and costs perfectly above an equal AMD CPU, Group Red will possibly proceed to keep an general price tag/general performance edge.
