As promised earlier, AMD has unveiled its latest Zen 3 CPU micro-architecture via an online event on October 8. The highlight of the event was the Ryzen 9 5900X which the company is claiming to be the best gaming desktop processor. Keep reading to learn more about the Zen 3 and AMD Ryzen 5000 Ryzen Desktop processors, including the specs, features, pricing, and availability.
Zen 3 CPU Microarchitecture
The new Zen 3 architecture sees the biggest improvement that AMD has been able to pull off in subsequent releases since the introduction of Zen architecture back in 2017. AMD says the new architecture has been built up ground up. However, AMD has not transitioned to a smaller node. We will see this with next year the Ryzen 4, based on 5nm.
For now, the Zen 3 architecture is based on the same 7nm node as its predecessor. Yet, the company has made changed to the underlying core architecture. It is still using the chiplet design although AMD has modified the core complex. In Zen 2, a Core Chiplet Die (CCD) consisted of two Core Complexes (CCX) with up to 4 cores and 16MB L3 cache each. The CCX had Infinity Fabrics in between for communication.
In Zen 3, AMD has combined the two CCX to form a single unified core complex. Each core complex consists of 8 cores with a 32MB core cache. Each core can now access the 32MB cache. It also improves the core to core communication. As cores in a CCD can communicate directly without the need of Infinity Fabrics, the memory latency has also been improved. AMD is also claiming up to 19% improvement in the IPC (Instructions Per Cycle).
Other than that, the I/O diode has remained the same, which means the Zen 3 has the same PCIe compatibility and USB support as the Zen 2.
Ryzen 5000 series Desktop Processors
The Ryzen 5000 series desktop processors are the successor to the Ryzen 3000 series. AMD has dropped the Ryzen 4000 series so as to maintain uniformity in the naming of desktop and mobile processors. As of now, there are only 4 processors in the lineup. These processors have the same core/thread count as their predecessor with higher clock speed and increased IPC. All that, without any increase in power consumption. It is said to have 59% better rendering performance than the Intel Core i9-10900K.
Ryzen 9 5950X
It is the highest-ranked processor in the new Ryzen 5000 lineup. The processor features 16 cores and 32 threads and is based on the same 105W TDP as the 3950X. It is the fastest processor in the lineup with a boost frequency of up to 4.9GHz. The base frequency is listed at 3.4GHz. The total cache here is the 64MB (72MB in total). It is targetted towards content creators.
Ryzen 9 5900X
AMD is calling the Ryzen 9 5900X as the “world’s best gaming CPU”. It features 12 cores and 24 cores. The base frequency here is 3.7GHz and it can attain a boosted frequency of up to 4.8GHz. It has 19% better IPC while still running on the 105W TDP. It offers an average gaming performance boost of up to 26%.
While its Intel counterpart (the i9-10900K) has been ahead of the Ryzen processor in the single-thread performance, AMD says it is no longer the case with the 5900X. AMD says it is the first desktop processor to surpass 600 points in the Cinebench R20 1T test. The 631 score is significant if you consider that the i9-10900K scores 544 in the same test. Similarly, the 5900X is 28% more power-efficient than the Intel counterpart.
Ryzen 7 5800X
The Ryzen 7 5800X features a single core complex. That is, it has 8 cores and 16 threads. The cache size here is 36MB (L2+L3). It is listed with a base clock speed of 3.8GHz which can reach up to 4.7GHz. The TDP here is 105W.
Ryzen 5 5600X
Ryzen 5 5600X is the cheapest and least powered processor in the Ryzen 500 desktop process lineup. It features a single core complex with six cores and twelve threads. The base clock and boost clock speed of the processor are listed at 3.7GHz and 4.6GHz respectively. It is the only processor in the lineup to have a TDP of 65W. Similarly, it is the only one to come with a stock cooler.
Ryzen 5000: Motherboard Compatibility
The new Ryzen 5000 desktop processors are compatible with B550 and X570. AMD will be rolling out and BIOS update for the same. According to the Gamer Nexus, the X470 and B450 will also be receiving the update. It is said to be available in 2021.
AMD Ryzen 5000 Desktop Processors Price & Availability
The AMD Ryzen 5000 processors will be available on November 5 and the price starts at $299 for the Ryzen 5 5600X. Top of the line Ryzen 9 5950X has a price tag of $799. AMD has bumped the price of Ryzen 5000 desktop processors by $50 compared to their respective predecessors.
|AMD Ryzen 5000 Desktop CPU||Price (US)||Availability|
|Ryzen 9 5950X||$799||November 5, 2020|
|Ryzen 7 5000X||$549|
|Ryzen 5 5800X||$449|
