AMD officially announced its Zen 3 architectured Ryzen 5000 series CPU on 8th October 2020 and launched a few processors in this lineup. These CPUs are Ryzen 9 5950X, Ryzen 9 5900X, Ryzen 7 5800X, and Ryzen 5 5600X.
AMD skipped using the ‘4000’ model numbers as the 4000 series CPUs are available in mobile devices. This is to avoid any confusion between the laptop and desktop processors.
Zen 3 Architecture
The Zen 3 architecture was officially announced by AMD CEO Dr Lisa Su in 2017 in a roadmap which is manufactured on the TSMC’s 7nm+ process. The new 7nm+ node has 20% more density than the 7nm node on which the Zen 2 processors are made and provides 10% power reduction1)https://en.wikichip.org/wiki/amd/microarchitectures/zen_3.
Ryzen 9 5950X Specs and Price
AMD’s Ryzen 9 5950X is the flagship CPU in the 5000 lineup and features 16 cores and 32 threads with 64MB of L3 and 8MB of L2 cache memory. All of the specs of 5950X matches with the last-gen 3950X on the paper except for the core clocks2)https://www.amd.com/en/products/cpu/amd-ryzen-9-5950x.
It features a base core clock of 3.4GHz which is 100MHz slower than the base clock of 3950X while its boost clock is 4.9GHz which is 200MHz more than what 3950X has.
Ryzen 9 5950X is priced at a $799 which is $50 more expensive than the launch price of Ryzen 9 3950X.
Ryzen 9 5900X Specs and Price
Ryzen 9 5900X replaces Ryzen 9 3900X and presents a similar case as that of 5950X. It features 12 cores and 24 threads with base/boost clock of 3.7GHz/4.8GHz. The base clock is 100MHz slower than the 3900X while the boost clock is 200MHz faster. It has 64MB of L3 and 6MB of L2 cache memory with TDP as 105W which is common across the 4 CPUs discussed3)https://www.amd.com/en/products/cpu/amd-ryzen-9-5900x.
Ryzen 9 5900X will launch at a price of $549 which is $50 more than the initial launch price of Ryzen 9 3900X but the price of the latter was reduced to $420 after the launch of Intel Core i9 10900K processor4)https://wccftech.com/amd-slashes-ryzen-9-3900x-cpu-pricing-in-the-wake-of-intels-10th-generation-launch/.
Ryzen 7 5800X Specs and Price
Ryzen 7 5800X comes with 8 cores and 16 threads clocked at 3.8GHz/4.7GHz compared to 3.9/4.5GHz of Ryzen 7 3800X. They both feature the same TDP of 105W and a total cache memory of 36MB.
Ryzen 7 5800X is priced at $449 which is again $50 costlier than the initial price of Ryzen 7 3800X but the 3800X is right now available for less than $350.
Ryzen 5 5600X Specs and Price
Ryzen 5 5600X features 6 cores and 12 threads with base/boost clock speeds of 3.7GHz/4.6GHz. It replaces the Ryzen 5 3600X but the TDP is now reduced from 95W to 65W only5)https://www.amd.com/en/products/cpu/amd-ryzen-5-5600x. The total cache memory available on this chip is 35MB and unlike the 4 processors mentioned above, it comes with a stock cooler: Wraith Stealth.
It’s priced at $299 which is $50 more than Ryzen 3600X and $100 more than Ryzen 3600(Non-X variant).
Ryzen 5000 Memory Support
There is no difference between the 3rd gen i.e., Gen 2 processors and Gen 3 processors when it comes to memory support. Both of these CPU series support 3200MHz of RAM configuration out of the box.
Ryzen 5000 Motherboard Support
Ryzen 5000 series CPUs won’t be compatible with the already available motherboards having chipsets other than B550, X470 and X570. Earlier it was thought that these CPUs won’t be compatible with X470 either but AMD has officially announced that they are working on the BIOS update on X470 motherboards to support the Ryzen 5000 series CPUs.
AMD recommends that the users should upgrade their BIOS to AGESA 18.104.22.168 or newer if they own an X570 motherboard for the best experience. While a new BIOS update for B450 and X470 motherboards will be available in January 2021.
Ryzen 5000 Performance
The Zen 3 architecture is said to provide 19% higher IPC(Instructions Per Clock) over the Zen 2 architecture which gives a significant improvement in gaming performance and single-threaded as well as multi-threaded performance.
The new design also shows how the cores now have direct access to the 32MB of cache memory as the new dye layout features 8 cores per CCX instead of 4 cores per CCX x 2. This should reduce memory latency and provide a quick response in operations.
AMD also show gaming benchmarks comparison between the Ryzen 9 3900XT and Ryzen 9 5900X where the 5900X takes lead on the 3900X from 5% up to 50%. These are their own benchmark numbers and may not be fully unbiased just as we saw the difference in benchmarks between those provided by AMD and by reviewers previously during the launch of older Ryzen series CPUs.
Ryzen 5000 series CPUs availability
Zen 3 based Ryzen 5000 series processors that include the Ryzen 9 5950X, Ryzen 9 5900X, Ryzen 7 5800X, and Ryzen 5 5600X, are set to launch on 5th November 2020.
