AMD Ryzen 9000 “Zen 5” introduces Specs and Anticipated Launch Date

AMD has been stirring up the processor market with its Ryzen series, and the upcoming Ryzen 9000 processors are no exception. Set to launch later this year, the Zen 5 core architecture promises significant improvements in single-threaded performance, particularly benefiting gaming enthusiasts.

Thanks to a leak in late September from Moore’s Law is Dead, we now have a closer look at the finer details of the Zen 5 core and its capabilities. Codenamed “Nirvana,” the Zen 5 architecture brings upgrades across various aspects, including the frontend, backend, memory subsystem, and cache.

Starting with the frontend, the Zen 5 core sees enhancements in key areas such as the L1I data cache, which has been increased from 32KB to 48KB 12-way. This cache sits next to the decoder and branch predictor, contributing to faster address translation. Speaking of the branch predictor, it plays a crucial role in an out-of-order CPU like Zen 5, dictating the pipeline’s flow and affecting instructions per cycle (IPC). Zen 5’s branch predictor executes “Zero bubble” conditional branches, allowing access to the Branch Target Buffer without penalties or bubbles.

Moving on to the backend, AMD has focused on strengthening the Integer Execution capabilities of Zen 5. The ALU count has been increased from 4 to 6, accompanied by a larger Scheduler. On the Vector/FP Side, 512-bit wide FP units have been added to improve AVX512 performance. While the wider ALU may be limited to EPYC products, it is expected to be fused on the Ryzen 8000 CPUs.

The Memory Sub-system of Zen 5 has also received attention. It can now handle 4 loads or 2 stores per cycle, an improvement over Zen 4’s 3 loads per cycle. These enhancements contribute to overall performance gains and smoother multitasking experiences.

In terms of core interconnect, the Ryzen 8000 processors, which will precede the Ryzen 9000 CPUs, will feature an upgraded core interconnect known as Ladder L3 Fabric. This interconnect, related to the 3rd Gen Infinity Fabric, will serve as the die interconnects for AMD’s next generation of chiplet products. While core counts and higher-level cache buffers are expected to remain unchanged, the Ryzen 8000 CPUs are anticipated to offer up to 16 cores across two CCDs, each with 32MB of L3 cache. The L2 cache will remain at 1MB per core or 16MB for the entire CPU.

With the Ryzen 8000 CPUs set to arrive in mid to late 2024, the Ryzen 9000 processors are expected to follow suit soon after. As for the launch date, it is likely to fall in the summer or fall of the same year.

AMD continues to push boundaries with its Ryzen processors, and the Zen 5 architecture promises to deliver impressive performance improvements. Whether you’re a gamer seeking better single-threaded performance or a power user looking for enhanced multitasking capabilities, the Ryzen 9000 processors are certainly worth keeping an eye on. Stay tuned for more updates on AMD’s latest products.
