AMD introduced the first third generation Ryzen processors at Computex 2019: Ryzen 5 3600, Ryzen 5 3600X, Ryzen 7 3700X, Ryzen 7 3800X, Ryzen 9 3900X. Here are the first technical information and performances.
AMD officially announced microprocessors Ryzen 3000 for desktops that will be available from July 7.
Company leader Lisa Su explained the new models ahead of Computex 2019 in Taipei. New microprocessors revealed by Su at CES 2019 in January, based on architecture Zen 2 and on the production process a 7 nanometers from TSMC.
With this generation, AMD takes a new approach to design and moves to a project involving a central I / O of 14 nanometers, where all connectivity lies, flanked by one or two chiplet at 7 nanometers, where we find the nuclei.
Each chip can count on a maximum of eight active cores, for a total of 16, although, for the moment, AMD has chosen to stop at 12 o'clock. Everything is connected via second-generation Infinity Fabric.
This design allows AMD to retain certain areas of the chip, such as memory controllers and I / O, on a successful production process such as 14 nanometers, while benefiting from performance, density, and performance. 7 nanometer process economy for important computing functions.
An innovative project, sign of a broader trend of the industry to the creation of heterogeneous architectures. How is architecture innovative Zen 2: AMD doubled mobile comma performance compared to Zen, cache size and 15% CPI improvement. And PCI Express 4.0 support is not lacking.
The offer is initially based on three productsor at least that's what AMD has been talking about for the moment. The first one calls Ryzen 7 3700X, is a processor with 8 cores and 16 wires that works at 3.6 GHz but can accelerate up to 4.4 GHz The L3 cache is 36 MB, while the TDP is 65 watts.
According to AMD, this processor offers 15% more performance per thread than the 2700X, a processor with a TDP of 105 watts, while multithreaded performance is up 18%. The 3700X has definitely proven itself Faster than a Core i7-9700K (95W) in Cinebench R20 at a public protest, but in general, AMD talks about Single-thread performance of 1% and more than 28% multi-threaded.
The second model is called Ryzen 7 3800X and retains the same design, but operates at 3.9 / 4.5 GHz in a 105-watt TDP. The processor offers gaming performance of 10 to 35% greater than that of a Ryzen 7 2700X e behaves much like a Core i9-9900K.
Finally, there is a third model called Ryzen 9 3900X, a processor that offers a second chiplet 12 cores and 24 wires. Operating frequencies are 3.8 / 4.6 GHz, ha 70 MB of L3 cache and a TDP of 105 watts. This processor proved to be faster than the Blender Core i9-9920X, with single and multi-threaded performance greater than 14% and 6% respectively. All this considering that the Core i9 has a TDP of 165 watts compared to the 105 watts of the AMD chip.
This processor offers 32% more single-threaded and 100% multi-threaded performance than the Ryzen 7 1800X, high-end of the first generation of Ryzen.
We come to price: we are talking about duty-free price lists, but they are absolutely interesting with $ 329 for the 3700X, $ 399 for the 3800X and $ 499 for the 3900X.
On the sidelines of the official press conference, AMD updated its site by introducing two other models: these are solutions Ryzen 5 to 6 cores / 12 wires, both with 32 MB of L3 cache. Ryzen 5 3600X operates at 3.8 / 4.4 GHz and has a 95 Watt TDP while Ryzen 5 3600 it operates at 3.6 / 4.2 GHz and has a TDP of 65 watts.
All models have a dual-channel DDR4-3200 memory controller and an unlocked multiplier. Regarding AM4 motherboard compatibility, AMD has released an image that looks at the situation and can be seen below.
However, chipset-based motherboards will also be on the market X570, with a maximum of 40 PCI Express 4.0 lines (20 are in the processor, the same number offered by the platform), able to ensure full compatibility with the new Ryzen but also with future PCIe 4.0 video cards such as the Radeon RX 5000 Navi and new SSDs generation.
