In excess of the past number of weeks, chatter has amplified about Rocket Lake’s effectiveness and corresponding benchmark leaks. We have noticed a quantity of Geekbench success for several CPUs and composed a several comparisons ourselves. Since the leaks continue to keep coming, it seemed a lot more useful to spherical up anticipations for RKL and how it’ll most likely evaluate to Zen 3 / Ryzen 5000, somewhat than carry on dissecting every single leak separately. We’re evaluating CPUs here fairly than platforms, but Rocket Lake also introduces capabilities like PCIe 4. for Intel CPUs.

Rocket Lake utilizes Intel’s Cypress Cove CPU architecture. Cypress Cove is a backport of Intel’s 2019 Ice Lake architecture, developed on the company’s older 14nm process. Intel has ongoing using 14nm for desktops, despite having 10nm in-current market for cell, since the features of the node have been superior suited to building high-performance multi-core CPUs. Cypress Cove is expected to supply ~1.19x bigger IPCs than Comet Lake, and it provides AVX-512 guidance to buyer methods. But how will this in fact review towards AMD?

Very first, we anticipate Rocket Lake to deliver robust one-thread effectiveness improvements. At any time given that AMD introduced Ryzen, Intel has emphasized large one-threaded overall performance. AMD claimed the gaming industry with the start of the Ryzen 5000 collection, but Rocket Lake features Intel a chance to seize it back again once again. Numerous leaked effects advise Rocket Lake’s one-threaded functionality is someplace among one.17x – one.35x faster than the equivalent Comet Lake processor. Both would symbolize respectable generational uplift.

Intel will be at its strongest versus AMD in moderately threaded apps that do not scale perfectly higher than 8 cores. The anticipated IPC acquire is substantial enough to give Intel a genuine shot at recapturing gaming all round.

Rocket Lake’s multi-threaded functionality is a tiny more difficult to forecast. The exact same leaks that advise considerable solitary-threaded leaps from time to time predict more compact multi-threaded advancements of 1.1x – one.25x depending on the application and the CPU. Some leaked outcomes use engineering samples, not retail chips, and a extensive set of results is not unconventional. The most favourable leaks recommend that the Core i9-11900K will match or marginally exceed the Main i9-10900K’s general performance, even even though it only fields eight cores to its predecessors’ 10. The considerably less flattering predictions suggest the Core i9-11900K will arrive in just behind the 10900K. We’re possible to see the two these final results in exercise, depending on the diploma to which an application is or is not fond of Intel’s Cypress Cove architecture.

We don’t hope extraordinary improvements in electricity usage, considering that Intel is however performing with the similar 14nm node. We assume any energy performance enhancements Rocket Lake delivers to arrive courtesy of enhanced IPC as opposed to intrinsically decrease transistor-stage electricity use. If Intel has managed to enhance IPC and complete power usage, so a great deal the far better.

Rocket Lake is not heading to defeat AMD’s overall products stack. CPUs like the 5900X and 5950X will continue being complete efficiency leaders in properly-threaded applications. But Intel isn’t striving to display that its 8-main chip can defeat a 16-main CPU. Rocket Lake is supposed to exhibit that Intel can nevertheless move the desktop forward and strengthen IPC, whilst ideally profitable again precise segments like gaming. Back in 2018, Intel advised the assembled push it was functioning on a new system-agnostic structure methodology that would permit it to go CPUs amongst nodes substantially much more effortlessly than just before. Rocket Lake is a step in direction of that flexibility.

Over-all, we be expecting Rocket Lake to very seriously problem AMD on one-threaded overall performance, specifically in gaming. In multi-threaded, we hope the Core i9-11900K to match or slightly exceed the 5800X. AMD’s Ryzen nine 5900X and Ryzen 9 5950X will outpace Rocket Lake in any multi-threaded functionality comparison, but that is to be anticipated. Efficiency for every watt is probable to favor AMD. Overall performance per dollar will depend on how Intel rates its CPUs. If Intel charges aggressively, it might be able to pull off an upset from AMD at various value factors. If it sticks to its standard conduct and costs perfectly previously mentioned an equivalent AMD CPU, Workforce Crimson will likely carry on to retain an all round cost/functionality edge.
