AMD Ryzen 5000: Every part You Have to Know

The AMD Ryzen 5000 series is a pioneering CPU generation. Not only is it the last generation of AMD processors to use their AM4 socket, but it is also the first that Team Red's chips claim to reliably beat Intel's top gaming products.

Ryzen 5000 also represents a leap in nomenclature compared to previous generations. Instead of the expected Ryzen 4000 lineup, the new desktop CPUs jumped forward to Ryzen 5000 in line with the Zen 2 mobile CPUs released earlier this year.

This could mean that AMD's mobile and desktop CPUs with the same architecture will use the same naming scheme in the future. We'll have to wait for the Zen 3 mobile CPUs to debut to find out, however.

Right now we only know about the desktop chips and they look great.

Prices and availability

AMD officially announced the Ryzen 5000 series on October 8th (watch the event here), which lists a range of four different desktop CPUs. They should go on sale on November 5th. The 5600X is priced at $ 299, the 5800X is $ 449, the 5900X is $ 549, and the 5950X is $ 799.

With AMD's Ryzen 4000 series mobile processors growing in popularity among laptop manufacturers, it is unlikely that we will see the debut of the 5000 series mobile processors anytime soon. As a rule, AMD announces the dates for the new year, so we don't have to expect information about them until early 2021 at the earliest. The actual laptops with these CPUs will debut later this year.

Architecture

AMD Zen 3 architectural layout

AMD's Zen 3 architecture builds on the success of Zen 2 and includes some significant changes that can result in performance improvements.

Zen 3 is based on the same 7 nm process node as Zen 2 and uses the same chiplet layout. Instead, Zen 3 is switching from a CCX design with four cores to a unified CCX with eight cores. This allows the L3 cache to be shared across a larger number of cores, so that individual cores can effectively access twice as much cache as before. Cache latency is reduced, which can have a measurable impact on game performance.

Wider float and integer engines, expanded load / store flexibility, and a new zero-bubble branch prediction system allow, as AMD claims, an improvement in instructions per clock (IPC) by up to 19%.

That's bigger than even the most optimistic rumors suggested. Ryzen 5000 borrowed many of the improvements from AMD's Epyc Rome server CPUs, which also benefit from a unified cache design.

Third-party reviews are a must to confirm real-world performance. However, based on AMD's preview of the chips at the first-party Zen 3 release, we can expect Ryzen 5000 chips to deliver strong results.

Ryzen 5600X Ryzen 5800X Ryzen 5900X Ryzen 5950X
Cores 6th 8th 12 16
subjects 12 16 24 32
L2 + L3 cache 35 MB 36 MB 70 MB 72 MB
Base clock 3.7 GHz 3.8 GHz 3.7 GHz TBD
Max. Single core boost clock 4.6 GHz 4.7 GHz 4.8 GHz 4.9 GHz
TDP 65W 105W 105W 105W

Since the Zen 2 CPU did not achieve the initial boost clock targets when it was first released, AMD's clock speed claims should be viewed with a skeptical lens for the time being. Single-core clocks might not be as high for everyday tasks, especially since most workloads, including older games, use a handful of cores each. AMD also didn't mention all-core boost numbers, which are likely more applicable, especially for lower-tier processors.

In terms of performance, AMD hasn't detailed the benchmark results for all new generation CPUs and instead has focused on the mainstream flagship 5900X. In the Cinebnech 1T, which focuses on single-threaded performance, AMD showed that the 5900X is the first CPU to break the 600-point mark at standard speeds, significantly outperforming the Intel Core i9 10900K.

It also made strong claims about its gaming performance, showing improvements between five and 50% on a selection of games at 1080P resolution compared to the last generation Ryzen 3900XT. Most gamers spending nearly $ 550 on a CPU are unlikely to play at this resolution, but this is the best for demonstrating the raw performance improvements the AMD CPU has to offer.

5900X gaming performance

AMD also showed the same benchmarks with the 5900X versus the Intel Core i9 10900K flagship CPU and showed more modest, but still noticeable, performance gains. If these prove correct, it will be the first time in over 15 years that AMD has taken the CPU gaming crown.

The Ryzen 9 5950X is said to be even faster in terms of both productivity and gaming, although AMD hasn't given direct numbers against Intel's best in that regard.

We need real-world performance tests from third-party reviews (like us!) To see how accurate these results are. However, leaked benchmarks from earlier this year can give us a clue. A result of a leak from Twitter user @TUM_APISAK for Ashes of the Singularity showed that the Ryzen 7 5800X handily beat the Intel Core i9 10900K at 4K.

A few days after the Ashes of the Singularity benchmark, a CPU-Z screenshot made the rounds showing a Ryzen 7 3700X against an unnamed AMD CPU. The screenshot shows 12 cores and 24 threads. So it's probably the Ryzen 9 5900X. The benchmark showed a 25% improvement in single core performance and a 15% improvement in multithreaded performance over the last generation 3900X.

While we can't confirm any of the benchmarks right now, we should be able to do so soon and before AMD launches RDNA 2 GPUs later this year.

The AM4 socket is retained for the time being

One of the best features of AMD's Ryzen CPUs was the cross-generational support for the same AM4 socket. Those who bought older generation Ryzen CPUs and motherboards have been able to update their processors without buying a new motherboard – all they have to do is update the BIOS. This will also be the case with Zen 3 Ryzen 4000 processors, although this will be the last generation of Ryzen chips to use the AM4 socket.

The Ryzen 5000 CPUs support existing X570 and B550 cards with a BIOS update as well as selected X470 and B450 cards with a non-reversible BIOS update if the manufacturers support this. There was no news about a Zen 3-specific chipset, although rumors of an x670 design have been around for well over a year.

Some suggested that it would offer improved PCIe Gen 4.0 support, as well as increased I / O via additional M.2, SATA, and USB 3.2 ports. Wccftech reported that native Thunderbolt 3 support on this chipset may still not be available.

AMD's next-generation Zen 4 CPUs, expected in 2021, will move beyond AM4 to a new AM5 socket design that, according to Wccftech, is supposedly based on technologies like DDR5 memory and PCIe 5.0.
