AMD on Thursday introduced the Ryzen 5000 collection, its flagship client desktop CPUs for gaming and creation. And if the corporate’s smattering of benchmarks are to be believed, it is managed to squeeze fairly a efficiency enhance out of the brand new processors with out altering the essential specs — like variety of cores, complete cache and energy envelope — and simply switching to the brand new Zen Three structure. AMD additionally gave us a quickie preview of the eagerly anticipated Radeon RX 6000 graphics card, which it will launch on Oct. 28.

The CPUs mark the debut of Zen 3, which builds on the earlier technology of AMD’s 7-nanometer structure with optimizations that the corporate says ship round 19% extra directions per clock cycle over the 3000 collection — which is already fairly quick — throughout the board. One of many large modifications between generations is a transfer from a four-core block to eight-core blocks within the die structure, with double the quantity of L3 cache. In observe, meaning extra reminiscence is nearer to the cores on the CPU die, lowering general latency, which implies it responds extra shortly for any CPU-related actions.

Ryzen 5000-series CPUs

Base clock Increase clock Cores/threads Cache System energy goal (watts) US value
Ryzen 9 5950X 3.4 4.9 16/32 72MB 105 $799
Ryzen 9 5900X 3.7 4.8 12/24 70MB 105 $549
Ryzen 7 5800X 3.8 4.7 8/16 36MB 105 $449
Ryzen 5 5600X 3.7 4.6 6/12 35MB 65 $299

Zen Three CPUs additionally get a lift from extra environment friendly arithmetical operations and instruction prediction. All whereas reaching a 24% enchancment in efficiency per watt, in line with AMD, and they’ll have the ability to work in the identical motherboards. Base and increase clock speeds are solely barely completely different from their predecessors. So far as I can inform, there are not any modifications in supporting chipset-related specs, corresponding to most quantity of reminiscence or variety of PCI Four lanes.

You may discover there’s nonetheless a niche within the lineup the place a 10-core choice to compete instantly with the Intel Core i9-10900Okay could be.

AMD’s goal launch date of Nov. 5 is aggressive, particularly since Intel has but to unveil its competing flagship next-generation desktop CPUs. Intel recently confirmed that the brand new structure, code named “Rocket Lake,” based mostly on Cypress Cove (10nm cores tailored and validated for Rocket Lake’s 14nm course of) would first seem within the 11th-gen midrange Rocket Lake-S chips in early 2021. Intel claims its Rocket Lake processors could have higher efficiency with extra IPC — sarcastically, a metric AMD pushed into reputation over clock frequencies just a few years in the past — help for PCIe 4.0, expanded AI acceleration capabilities and Xe graphics structure, with its a lot sooner built-in graphics.

The brand new processors bounce the 4000-series naming conference, probably to get rid of confusion with the Zen 2-based cell processors that bear that designation. 

For its preview of the the RX 6000 (nicknamed “Huge Navi”) graphics card line, which contains the RDNA 2-architecture we have heard a lot about with the upcoming Xbox Series X and PS5 consoles, AMD highlighted 4K efficiency. That is somewhat uncommon for the corporate, which has been concentrating on selling its 1440p functionality on the increased finish of the RX 5000 line. It is not shocking, although, provided that its related new console chips goal 4K at 120fps.
