Like previous-gen Ryzen 5000 series processors, the top-end Ryzen 9 7950X tops out at 16-cores / 32-threads, and core counts and cache decrease as we work down the stack. The initial lineup of AMD Ryzen 7000 series processors will consist of four SKUs, the Ryzen 9 7950X, Ryzen 9 7900X, Ryzen 7 7700X and Ryzen 5 7600X. ![]() In terms of performance, AMD is claiming a 1.3x improvement in FP32 inferencing workloads versus Zen 3, and up to a 2.5X improvements for Int8. This design decision was reportedly made to avoid large frequency fluctuations when executing AVX-512 workloads. In Zen 4, however, AVX-512 is implemented using double-pumped 256-bit data chunks unlike Intel’s latest architectures. The Zen 4 architecture also incorporates support for AVX-512. For example, 65 watt processors exhibit up to a 74% performance improvement, 105 watt processors up to 37%, and 170 watt processors up to 35%. The performance scaling, however, varies significantly at different TDPs. Zen 4 offers 62% lower power at similar performance levels to Zen 3, or 49% higher performance at similar power. Zen 4’s performance per watt is significantly improved as well. This too, however, is complicated because the processors are designed to shoot up to a maximum 95☌ TJMax to take advantage of any available thermal headroom and maximize performance. ![]() On a related note, despite the smaller dies resulting in higher thermal density and the smaller / lower-mass integrated heat spreader design on Ryzen 7000 series processors versus their predecessors, AMD claims thermals are improved under many circumstances. However, the overall power story with Zen 4 is complicated, as a roughly 50% reduction in idle power and the integration of many mobile-first power-savings technologies were incorporated into the architecture and platform, but high-end system configurations actually pull more power from the outlet-more on that a little later. The first batch of Ryzen 7000 series processors going on sale tomorrow will have a TDP of 170 Watts, though socket power increases up to 230 watts to build some future scalability (and overclocking headroom) into the platform. There is a ton to cover, so without further delay, we should probably get right to it. We also have some fresh details to share with you today about Zen 4 and the platform as a whole. However, today we get to actually take the processors for a spin on our own and show you how they perform in a variety of workloads and benchmarks. New chipsets also are arriving alongside the Ryzen 7000 series, and the platform also supports PCIe 5.0 and requires the latest DDR5 memory.ĪMD has disclosed virtually everything about the Ryzen 7000 series, its supporting chipsets, and the Zen 4 architecture. The processors are based on a new microarchitecture and they move away from PGA (pin grid array) package designs in favor of LGA (land grid array). Lisa Su and other members of the executive team revealed four new processors in the Ryzen 7000 series, and showed off an array of new motherboards and memory designed for the platform.Īt this point, many of you will know that the Ryzen 7000 series signifies a big step forward for AMD. Last month, AMD officially took the wraps off of the Zen 4-based Ryzen 7000 series processors during its “ together we advance_PCs” livestream event.
