AMD’s first Zen 5 CPU is the ‘monster’ Ryzen 9 9950X
AMD is launching its first Zen 5 desktop processors in July, with the Ryzen 9 9950X flagship leading the pack as “the world’s most powerful desktop consumer processor.” Based on AMD’s existing AM5 platform, the new Ryzen 9000 series of CPUs include the Ryzen 9 9950X, Ryzen 9 9900X, Ryzen 7 9700X, and Ryzen 5 9600X.
- The flagship Ryzen 9 9950X is a 16-core, 32-thread CPU, with 80MB of L2+L3 cache and a 5.7GHz boost clock.
- AMD is promising around a 16 percent instructions per cycle (IPC) uplift in performance over the previous-generation Ryzen CPUs.
- The Ryzen 9000 series lineup includes the Ryzen 9 9950X, Ryzen 9 9900X, Ryzen 7 9700X, and Ryzen 5 9600X.
AMD’s Zen 5 architecture and AM5 platform
At the heart of the 9950X is AMD’s new Zen 5 architecture. It’s still using the AM5 socket, with the usual PCIe Gen 5 and DDR5 support, but there are some updates under the hood to deliver more performance that AMD argues make this not a trivial update.
- “Sometimes there are updates of Zen that are not as fundamental, but Zen 5 is a sweeping update with vastly improved branch prediction for both accuracy and latency,” says Woligroski.
- “It’s a really impressive difference, and this delivers up to twice the instruction bandwidth, up to twice the data bandwidth, and up to twice the AI performance of the last gen.”
- AMD originally promised that the AM5 socket, which launched in 2022, would keep seeing new processor support until at least 2025, but it’s now extending that commitment at Computex to 2027 or beyond.
Ryzen 9000 series launch and AM4 support
AMD’s new Ryzen 9 and Ryzen 7 CPUs for the AM4 socket will all launch in July, but AMD isn’t providing pricing for any of the processors yet.
- The Ryzen 9 9900X will include 12 cores, 24 threads, and a 5.6GHz boost.
- The Ryzen 7 9700X ships with eight cores, 16 threads, and a 5.5GHz boost clock.
- The Ryzen 5 9600X will have six cores and 12 threads, alongside a 5.4GHz max boost.
