Architecture Zen 3 behind the AMD desktop CPUs Ryzen 4000 (without integrated GPU) arriving in the last part of the year could be better than even the most optimistic expectations. The previous corridor entries indicated a average increase in IPC performance (instructions processed per clock cycle) between 15% and 17% compared to the Zen 2 cores, but according to the latest rumors Zen 3 would be even faster.
"Ice Universe", a leaker that has proven reliable in the past, he claims that the engineers of two well-known OEM manufacturers would have confided to him that the performance of the Ryzen 4000 would reach an "alarming level". Alarming not in a negative sense, or at least not for AMD, but for the competition represented by Intel. "Based on current information on Intel products owned by these two OEMs, AMD's 4th generation Ryzen will completely beat Intel both in terms of performance and consumption".
These are interesting statements, but they must be taken with a moment of caution because we do not know which Intel products the Ryzen 4000 would have been compared to, whether the current Core 10th Gen (Comet Lake) range just presented or the future Core 11th Jan (Rocket Lake) expected later this year. The most suitable comparison would be precisely with Rocket Lake, which according to rumors will be Intel's first desktop CPU with a new architecture from the time of Skylake.
The US company would have adapted the new generation Sunny or Willow Cove cores and the integrated Xe graphics to the 14 nanometer production process, adding PCI Express 4.0 support to the mix. The goal would be to improve the performance of the architecture by maintaining high operating frequencies thanks to the maturity of 14 nanometers. As far as we know, Sunny Cove architecture improves (on average) the IPC compared to Skylake by 18% (there is no information on Willow Cove), and therefore based on the current comparison Zen 2 – Skylake, which have IPC performance similar, we could witness another "draw" between the architectures, at least on the IPC front.
However, it seems that based on internal tests, the IPC of the Zen 3 CPUs will improve more than 17%, which was already a very interesting figure. Although with all the necessary precautions, as it is not an official statement, Zen 3 could offer up to 20% better IPC than Zen 2, so much so that some fresh buyers of Ryzen 3000 CPUs could be tempted by the "jump"; the problem is that it will be necessary to change the motherboard, according to what has been declared by AMD, with the transition to the solutions equipped with chipsets B550 and X570.
