With the Zen architecture, AMD has made a remarkable comeback in recent years, as CPUs on the Zen architecture are able to compete with, and in some cases even surpass, Intel's processors. AMD's Zen 5 processors are the next generation of CPUs and are sure to bring further improvements and innovations in the architecture and performance of AMD's processors. Despite AMD's progress, there are still many questions about the exact performance of the Zen 5 processors. However, the new leaks from two well-known YouTube leakers have not brought much clarity. This is because there is a disagreement about how fast the Zen 5 processors will actually be. So they know that they don't actually know anything.
YouTubers Moore's Law is Dead (MLID) and RedGamingTech (RGT), have published detailed information about Zen 5. The two YouTubers have already made successful forecasts and assessments of new technologies and products in the past, but have also been miles off the mark from time to time. The desktop chips, which are intended for use in PCs and laptops, are to be manufactured in 4nm. This means that the transistors that make up the chips will be even smaller than in the current Zen 3 processors, which are manufactured in a 7nm process.
The APUs, which are designed as a combination of processor and graphics chip, could be manufactured in 3nm, while some others could be manufactured in 4nm. This suggests that AMD may be targeting different performance levels for different markets. Finally, it is also mentioned that next-generation server chips could also be manufactured in 3nm. This could indicate that AMD plans to further expand its presence in the server market, as these chips are typically used in data centers and other enterprise environments.
The big news relates to the upcoming Zen 5 processor lineup, which is expected to feature an overall performance increase compared to the current Ryzen 7000 lineup. The IPC increase, i.e. the number of instructions that a processor can execute per clock, should be between 20 to 25% higher, according to RGT. This means that the processors will be able to execute more instructions in a given period of time and thus achieve higher computing performance. Such an increase can be especially beneficial for compute-intensive applications and tasks such as video and image processing, 3D modeling, AI development, and gaming.
Single-threaded tasks refer to processes that are handled by a single CPU core, while multi-threaded tasks can be executed by multiple cores. An increase of more than 25% in single-thread performance would be a significant improvement. It is unclear what type of tasks the forecast is, as this is not explained in detail. For example, it could be games, applications, or other complex processes. RGT's statement is promising, as it promises a potential improvement in performance for certain processes. However, it remains to be seen whether this prediction will actually come true and how this will affect the overall performance of the system.
According to the two leakers, the new processor will have a larger cache and will be part of a speed increase. The architecture will also be revised and polished, which will lead to a considerable performance increase. The front-end will be wider and able to handle more commands simultaneously, while the back-end will have more resources. The clock rates will probably be increased slightly, but not as much as on the Zen 4. It is estimated that clock rates will increase by about 2% to 9%.
As for the number of cores, AMD will probably stick with 16 cores (32 threads) for the flagship, at least at the first launch. However, it is theoretically possible that AMD could get even tougher as development progresses and introduce a 32-core model. This model could be manufactured in 3nm instead of 4nm like the initial Zen 5 desktop lineup. Overall, the Zen 5 processors are expected to bring a considerable performance increase compared to the Zen 4 generation, although the clock rates are only slightly increased. The architecture has been thoroughly overhauled and polished, resulting in a broader front-end and more resources on the back-end.
MLID estimates that the Ryzen 8000 processors will have a performance increase of about 20%. Although a higher value is not excluded, it seems unlikely. Nevertheless, a 20% performance increase would mean a big leap for these processors. It is also mentioned that there are rumors that Zen 5 could be released at the end of this year, but these have proven to be false. Instead, Zen 5 processors are expected to hit the market in the first half of 2024. Some sources even believe that the first batch of desktop CPUs could be released in the first quarter of 2024, but this should be viewed with a fair amount of skepticism.
