AMD Ryzen 8000 “Zen 5” CPUs Set for 1H 2024 Debut: 16 Cores, Lower Clocks?

Expected to deliver a 20-30% increase in instructions per clock (IPC)
Introducing a "Ladder L3 Fabric" for core-to-core interconnect
Integrated AI and Machine Learning optimizations

AMD is reportedly gearing up to launch its next-generation Ryzen 8000 processors in the first half of 2024. These chips, based on the 4nm (TSMC N4) Zen 5 cores, are expected to prioritize single-threaded performance while keeping the core counts and Last Level Cache unchanged. According to RedGamingTech, the Zen 5 core is anticipated to deliver a 20-30% increase in instructions per clock (IPC), although it is unlikely to surpass the 20% mark.

Interestingly, it seems that the core clocks of the Ryzen 8000 CPUs might take a hit, with a potential decrease of 200-300MHz compared to the existing Ryzen 7000 parts. This is surprising considering that the N4 process is essentially a refined version of the N5 process, rather than something entirely new. Internally, the Zen 5 core is expected to feature enhancements such as a wider frontend, a larger Reorder buffer, and improvements to the lower-level cache.

One notable upgrade in the Zen 5 CCD core-to-core interconnect is the introduction of a “Ladder L3 Fabric,” which was initially leaked by AdoredTV. Additionally, the load-store units and L2 bandwidth are expected to be beefed up. AMD has also promised integrated AI and Machine Learning optimizations, which likely refer to low-precision modes like FP16 AVX512.

While the L1 cache is expected to see an increase in size, the L2 and L3 cache on the Ryzen 8000 CPUs will likely remain unchanged. The I/O aspect of these processors will also see minimal improvements, mainly focusing on memory speeds and timings. It’s worth noting that AMD performs AVX512 instructions on its Zen 4 designs using AVX256 units, which takes twice as long as native AVX512 units.

Considering Intel’s plans to reintroduce AVX512 to client PCs with its AVX10 package, AMD might opt to include additional execution units to support wider vector compute. Lastly, the Infinity Fabric, AMD’s high-speed interconnect technology, is expected to receive a frequency boost. An increase from 3000MHz to 3,500MHz or 3,600MHz should provide a significant improvement.

Overall, AMD’s upcoming Ryzen 8000 “Zen 5” CPUs appear to be focused on enhancing single-threaded performance while maintaining core counts and Last Level Cache. With anticipated IPC gains and various internal improvements, these processors hold the potential to deliver notable performance upgrades. However, it remains to be seen how the decrease in core clocks will impact overall performance and whether AMD’s optimizations for AI and Machine Learning will bring tangible benefits to users. As we await their debut in the first half of 2024, it’s clear that AMD is continuing its commitment to pushing the boundaries of processor technology.
