New generation of AMD Zen5/Zen6 processor exposed: using 2nm process, equipped with AI computing unit and 32 cores

AMD’s current strongest processor is the Zen4 processor, which has made significant progress in gaming performance. This processor uses a new 5nm process and AM5 socket. However, this processor has been launched for nearly a year, and consumers naturally expect AMD to launch a new processor. Recently, AMD’s roadmap for future CPUs was exposed online, including Zen5 and Zen6. In addition, this leak also revealed the parameters of the processor in detail

The first is the Zen5 architecture processor that everyone is more concerned about. The code name of the Zen5 processor will be called Nirvana, which means Nirvana. The improvement in IPC performance is actually not very large, about 10-15%, and For comparison, the IPC improvement of the Zen 3 architecture is 19%, while the IPC performance improvement of Zen 4 is about 15%. It seems that Zen5 is just like that in terms of single-thread performance. However, in terms of multi-threading performance, Zen5 should have a relatively large improvement, because the number of CCD cores has doubled and can support 16-core CCDs. The current CCD core uses 8 cores, and an AMD Ryzen CPU can support up to It has two CCDs, which means that 32 cores will be implemented on the Zen5 architecture processor.

In terms of data transmission, AMD’s Zen5 processor L1 cache has been increased from 32KB to 48KB, a rate of 50%. In addition, Zen5 has further improved data processing and throughput, and is expected to natively support higher-performance memory and SSD etc. The Zen6 processor is further improved on the basis of the Zen5 processor. The first is the process. The CCD process in the Zen6 processor will be upgraded to 2nm, while the I/O will be upgraded to 3nm. More importantly, the CCD core will be upgraded to 32 cores, which is estimated to be specially built for video users. The IPC improvement is not large, only 10%, but the deep learning unit and FP16 instructions built for AI are added, and the new packaging process will bring more efficient communication efficiency.

Regarding Zen5 and Zen6 processors, both are expected to use the AM5 socket. Currently, motherboards like the X670 should have no problem supporting Zen5 processors, and supporting Zen6 processors shouldn't be difficult either. However, if it is an entry-level A620 motherboard, it is likely that it does not support Zen6 processors. Of course, neither Zen5 nor Zen6 will be launched until at least 2024. Consumers should continue to wait
