AMD Ryzen 9000 Desktop CPUs Official: Zen 5 Achieves 16% IPC Uplift, 9950X, 9900X, 9700X, 9600X SKUs, Up To 16 Cores At 5.7 GHz, July Launch

wccftech.com:

AMD has finally announced its Ryzen 9000 "Zen 5" Desktop CPUs, arriving with up to 16 cores and featuring some huge IPC gains versus Zen 4.

AMD Ryzen 9000 Desktop CPUs Bring Up To 16 Cores, 5.7 GHz Clocks & 16% IPC Improvement, Ryzen 9 9950X Leads The Pack

The AMD Ryzen 9000 Desktop CPU family, codenamed Granite Ridge, is based on the latest Zen 5 core architecture and targets high-performance Gaming PCs. The family is bringing a range of new features with the Zen 5 cores being the highlight while being supported on existing and upcoming AM5 platforms with improved I/O and DDR5 memory support.

So before we talk about the Ryzen 9000 Desktop CPU family, we first take a glance at the new and improved Zen 5 core architecture which offers:

• Improved branch prediction accuracy and latency
• Higher throughput with wider pipelines and vectors
• Deeper window size across the design for more parallelism

In several aspects, the AMD Zen 5 core architecture offers up to a 2x increase such as the Instruction Bandwidth for the front-end instructions, data bandwidth (L2 to L1 and L1 to FP), and AI perf (AI & AVX512 Throughput). The Zen 5 CPU cores (CCDs) are based on the TSMC 4nm process node while the IOD is based on the TSMC 6nm process node. They come in the same peak config of 2 CCDs and 1 IOD on consumer platforms.

These new changes have resulted in a significant IPC uplift averaging 16% versus Zen 4. In certain cases, the Zen 5 core can reach up to +35% IPC such as (Geekbench 5.4 AES XTS) and another key area that has been improved upon is the L2 and L3 cache structuring. AMD also made some significant changes to the IMC which now result in much higher EXPO/XMP memory support and the Infinity Fabric clock has been raised from 2000 MHz on Zen 4 to 2400 MHz on Zen 5 with DDR5-5600 speeds natively supported.
