The third generation of Ryzen CPU from AMD is here, including the company's first CPU with 12 cores, the Ryzen 9 3900X. The company is announcing five new processors as part of the lineup, all with a release date of July 7. Their prices range from $ 199 to $ 499, and all of them are based on the company's new 7nm Zen 2 architecture with support for the new PCIe 4.0 interface, which offers double the PCIe 3.0 bandwidth.
At the top of the lineup is the Ryzen 9 3900X. This 12-core processor has a base frequency of 3.8GHz and is capable of increasing up to 4.6GHz. Next, the company has a pair of Ryzen 7 processors, the $ 399 3800X and $ 329 3700X. Both have eight cores with slightly different frequencies (visible in the table below), but the big difference is TDP, a basic indicator of the power consumption of a CPU. AnandTech notes that the 3700X has a TDP of only 65W compared to 105W for the 3800X, suggesting it could be a very efficient processor for the amount of performance it is getting. Finally, at the bottom of the alignment are the Ryzen 5 3600X and 3600 models.

AMD has some benchmarks to show how you expect your new CPUs to work. The company claims that its flagship 3900X will offer performance similar to Intel's i9-9920X even though it costs about half ($ 499 compared to $ 1,189). Meanwhile, AMD benchmarks suggest that the $ 329 3700X exceeds Intel's $ 374 i7-9700K in real-time processing performance of one or more threads. We will have to wait to test the new CPUs by ourselves to see how their performance accumulates in general use.
All new CPUs are based on the new AMD X570 chip set, which uses the same AM4 socket as the previous Ryzen CPUs from AMD. In theory, this means that if you already use a Ryzen processor, then you should be able to exchange one of the new CPUs in your system without having to update your motherboard. However, in practice, the power requirements of the new chips will mean that not all AM4 motherboards will support them. However, you will not face a lack of choice if you need to upgrade your motherboard for the new chips; AMD says there will be 56 X570 motherboards available from its partners when the new CPUs are released.
Far from its CPUs, AMD also joked with its next generation of graphics cards with a demonstration of the upcoming Radeon RX 5700. The GPU will run on AMD's new RDNA microarchitecture, which eventually replaces the existing GCN architecture that AMD introduced by first time in 2011. AMD states that, compared to its predecessor, RDNA offers a performance per clock 25% higher and a performance per watt 50% higher. It will also be one of the first GPUs that will support the new PCIe 4.0 interface. The new GPU is expected to launch in July.
