From a challenger position, Ryzen 5000 has helped AMD rise to the throne in the village of CPUs for personal computers.
When Dr. Lisa Su, president and CEO of AMD launched the Ryzen 5000 series CPUs with the latest Venmeer codename on October 8, the whole technology world was in a state of shock. Although it has started to flourish since the first generation of Ryzen was released in 2017, the 4th generation Ryzen with the new 5000 series marked the breakthrough of the “red team”. For the first time, Ryzen’s single- and multi-threaded performance has surpassed the competition.
One of the biggest innovations of Ryzen 5000 is the Zen 3 microarchitecture. Now, a silicon base or chiplet of Ryzen will only have a single CCX complex processor cluster with up to 8 cores at most. instead of 2 CCX clusters with 4 cores each. As a result, performance in applications using up to 8 cores is significantly improved because the latency when non-optimized applications place tasks on threads that are not the same CCX has been eliminated. This is also the general situation of most games today.
In this review, we will be testing the Ryzen 9 5950X and Ryzen 7 5800X representing the above-mentioned chiplet design. With 16 and 8 cores respectively, on the chip of these 2 CPUs there will be 2 and 1 chiplet respectively. In this new generation of CPUs, only CPUs from Ryzen 5 5600X with a TDP of 65W or less are equipped with Wraith dissipation. High-end CPUs with 105W TDP are oriented by AMD to need to use good performance air or water cooling to ensure heat dissipation for an abundant core count.
The box and packaging of the Ryzen 9 5950X and Ryzen 7 5800X are not too different from the previous generation. However, the gray has been somewhat darker. Despite being the top CPU, the Ryzen 9 5950X has a simple packaging that is no different from lower-end products. Personally, this is a bit of a disappointment when looking at the other side of the battle line with the special CPU packaging for the highest-end i9 CPU. That said, when buying computer components, people are more concerned with performance and price than the box. It’s so good that it’s sometimes made into a cigarette ashtray.
A commendable point of AMD is that socket AM4 is still in use after 4 years. Although backward support with older chipsets is quite limited, this is still a welcome approach by users. Of course, to get the latest features like PCIe 4.0 or the ability to enable AMD Smart Access Memory technology when combined with the upcoming AMD Radeon RX 6000 series of graphics cards, users will need to upgrade to the board. The motherboard is equipped with the latest chipset series X570 and B550.
Thanks to the new microarchitecture, the performance of the Ryzen 5000 CPUs is less dependent on the RAM clock as well as the clock of the Infinity Fabric microchip, especially in CPUs with 8 cores or less. The Infinity Fabric clock on Ryzen 5000 is still locked at 1800MHz with a 1:1 ratio with the RAM clock in a single-channel setting, so investing in RAM with a clock speed of over 3600MHz is not really necessary. The combination with a pair of 4000MHz RAM as in the test configuration only helps to slightly improve data processing performance.
