AMD Zen 3 Announcement

Tom's Hardware summarizes today's AMD Zen 3 announcement of the Ryzen 5000, saying this promises 19% better instruction per cycle throughput and "1080p gaming dominance." In their All We Know post they say these will first be available starting November 5th: "The first four new Ryzen 5000 models come as chips for the desktop PC, and they stretch from the $299 Ryzen 5 5600X up to the $799 Ryzen 9 5950X. The chips will be on shelves on November 5th." Here's word:
Undisputed no-compromise dominance of the desktop PC market. That was AMD's long-term goal when it first began working on the Zen architecture nine years ago, and it took an unrelenting cadence of optimizations to realize that goal. AMD claims it has finally achieved that ambitious goal with the 7nm Ryzen 5000 processors that come with the Zen 3 microarchitecture. AMD says the Ryzen 5000 processors finally beat Intel in its last bastion — 1080p gaming — while maintaining Ryzen's existing lead in basically every other metric. The four new Ryzen 5000 models, which stretch from the $299 Ryzen 5 5600X up to the $799 Ryzen 9 5950X, arrive at retail on November 5th.

AMD touts its Zen 3 chips as having market-leading single-threaded performance, which comes courtesy of an overall 19% uplift to IPC (instruction per cycle) throughput. Combined with the optimized 7nm process that wrings out a 4.9 GHz boost from the flagship Ryzen 5000 'Vermeer' chips, it looks like AMD has finally swung the pendulum entirely in its favor. If AMD's benchmarks prove true in our testing, we'll have a new king at the top of the CPU benchmarks hierarchy and will be making changes to our list of Best CPUs soon.

AMD says it took a ground-up redesign of the Zen microarchitecture (we'll cover the details below) to deliver the big IPC gains, and pairing that with higher peak clock speeds delivers stunning performance improvements over AMD's previous-gen Ryzen models, not to mention Intel's Comet Lake chips.

AMD claims the Ryzen 5000 chips are now faster than Intel in gaming, single-threaded, and multi-threaded performance while also providing leading performance-per-dollar and up to 2.8X better power efficiency than Comet Lake. That covers all the bases, and the chips also offer backward compatibility with existing 500- and 400-series chipsets, meaning they'll offer a relatively inexpensive path for drop-in upgraders.
