We now turn to the AMD processors, specifically to the Zen architecture that are giving them such good results. The company during the 'Day of the Financial Analyst of AMD', Lisa Su, CEO of the company has given data on Zen. It is the basis of the new Ryzen processors and reaps great successes. Su has talked about Zen3 and Zen4, which is already a lot.
Before talking about Zen, he has talked about the RDNA architecture for graphics cards, specifically he has given data on RDNA 2. Lisa Su promises a 50% performance improvement per watt by continuing with 7nm lithography. This is a very interesting piece of information, but perhaps what interests us most is that they support RayTracing by hardware.
- Default tdp / tdp: 65w
- Number of CPU cores: 8
- Max boost clock: 44ghz
- Thermal solution: Wraith Prism with RGB LED
- Pci express version: pcie 40 x16
Zen3 will be based on 7nm lithography
This year, possibly already in the second half of the year, we will see the Zen3 architecture processors. The company indicates that they will be based on the 7nm lithography, not to mention the 7nm EUV (7nm +) from TSMC. This lithograph will be used in the Ryzen 4000, the Threadripper 4000 and the EPYC Milan.
The less striking is that AMD does not reference the 7nm EUV, since it would be logical to move to a more polished lithography. This would offer improvements in performance and efficiency. But with no direct competition from Intel, they may want to keep pulling a lithograph that is working well for them.
The company indicates that Zen3 @ 7nm offers us a 17% increase in the CPI, which is very interesting without changing lithography. A 50% improvement in floating point operations has also been reported with a cache redesign.
Another interesting fact is that AMD until Q2 2019 had sold 150.000 million Zen cores (not processor, cores). Now the company in Q1 2020 already exceeds 260.000 million Zen cores sold, very relevant data. And the company offers very good solutions at a very affordable price.
