AMD introduces Zen 3 with 19 percent higher IPC and Ryzen 5000 processors
AMD announced its Zen 3 chip architecture on Thursday. The generation brings an increase of 19 percent in terms of instructions per cycle. On November 5, the first four Ryzen 5000X processors based on Zen 3 will be available, Zen 3 is the third generation of AMD’s Zen chip architecture that it started in 2017. Just like the Zen 2 announced last year, AMD has Zen 3 made at TSMC at 7nm. AMD confirmed once again that the successor Zen 4 will also appear in 2022 and will then be produced on a 5nm process. AMD cto Mark Papermaster explained the improvements of Zen 3 on Thursday. The generation offers a 19 percent higher ipc or instructions per clockcycle, where Zen 2 already offered a 15 percent higher ipc than the previous generation. AMD has made changes to cache prefetching, the execution engine and the micro-op cache to achieve the ipc improvement. The Zen 3 chips also offer a unified 8-core complex; Zen 2 is still made up of two core complexes of four cores. The advantage is that the eight cores on Zen 3 all have direct access to 32MB L3 cache, whereas the two four core components on Zen 2 both had to do with 16MB L3 cache. The performance-per-watt improvement of Zen 3 over Zen 2 is 24 percent, while both generations are produced on a 7nm node. AMD CEO Lisa Su immediately announced the first four Ryzen desktop processors based on Zen 3, the Ryzen 9 5950X, the Ryzen 9 5900X, the Ryzen 7 5800X and the Ryzen 5 5600X. As expected, the company is using the Ryzen 5000 name for the chips and keeping the Ryzen 4000 name for laptop chips and the Ryzen 4000G series of APUs, with the four processors coming available on November 5. The Ryzen 9 5950X is a sixteen-core processor that can handle 32 threads and offers a maximum boost frequency of 4.9GHz. With the Ryzen 9 5900X with twelve cores, gamers can expect an average performance gain of 26 percent over an identical system with a Ryzen 9 3900XT, AMD claims. AMD 500 series motherboards can handle Ryzen 5000 desktop processors after a BIOS update. The suggested dollar prices are $ 50 higher than the prices of the Ryzen 3000 desktop chips announced last year.Ryzen 5000X based on Zen 3
