AMD talks about Zen4 / Zen5: 7% IPC performance upgrade will not be disappointed on

If AMD has made the biggest change since launching the Zen processor in 2017, it’s that AMD is finally a long-term stable and reliable CPU roadmap, instead of left and right, as Intel’s Tick. Failed to counter talk strategy. This is the other way around. I’m not familiar with CPU roadmaps, and crafts and architecture are modest.

AnandTech’s website today released an interview with Mark Papermaster, chief technology officer for AMD, which asked a lot about the upcoming Zen processor plans, but it is impossible to publish official information, So this interview is very long, but basically it’s a routine, I hope the official leak can relax.

AMD is a simple compilation of the future Zen processor roadmap and IPC for CTOs.

According to Mark Papermaster, AMD’s recent CPU upgrade cycle is 12-18 months, a year faster, a year and a half faster, and a new generation of products can be seen almost every year.

For the CPU roadmap, AMD’s official announcement is for Zen 4, still, in design, Zen 3 design has been completed, 2020 was listed and should not run, and current product 7nm Zen 2 That is, the n – – 1, n – +2 roadmap

AMD now has several teams working on various projects, helping to successfully launch new products in 12-18 months. If the design had to be eliminated due to market development, then technologies that were not suitable for the current release would also be integrated into the next team (many designs on Zen 2 were originally made for Zen. ).

Regarding AMD’s design pattern of crossing at least two teams, some said they were learning Intel’s ticking tactics, but Mark Peppermust denied that saying That AMD’s way is to review and use every generation of CPUs. Combined with the best current IPC upgrades, memory cache systems and functions that AMD believes can be done, we are committed to improving the speed of each CPU generation.

An important point in AnandTech’s interviews is the improvement of IPC performance of the new generation Zen processor. Mark Peppermust certainly said he had no comment. He said that both performance and energy efficiency should be taken into account when designing a CPU core. There are many situations to consider.

However, Mark Peppermost promised that he pointed out that the industry level would improve IPC performance by about 7% every year. AMD’s target is not less than that number. AnandTech calculates that if this is the 18th upgrade generation, then the IPC performance of Zen2 to Zen3 is to be improved by 10.7%, with rounding of 11%.

This IPC increase is almost in line with the 10-15% IPC performance improvement mentioned by Deputy General Manager Forrest Norrod.

Prior to the interview, it was reported that Zen3’s IPC performance increased on average 17%, of which the integers are only 10 to 12%, but the improvement in floating-point was relatively large, 50% up to. Integer floating-point mixing operations improved by approximately 17%. The frequency also increased to 100-200 MHz or more, and the efficiency increase is still sufficient.

Likewise, in the future, Zen 4 and Zen 5 will not unexpectedly develop, and Zen4 may start using 5nm technology, will support PCI 5.0 and DDR5, performance will be more powerful.
