Zen 5 ("Nirvana")[1] is the name for a CPU microarchitecture by AMD, shown on their roadmap in May 2022,[2] launched for mobile in July 2024 and for desktop in August 2024.
[10] The earliest details on the Zen 5 architecture promised a "re-pipelined front end and wide issue" with "integrated AI and Machine Learning optimizations".
[13][14] Additionally, Apple, as TSMC's largest customer, is given priority access to the latest process nodes.
[15] After N3 began ramping at the end of 2022, Apple bought up the entirety of TSMC's early N3B wafer production capacity to fabricate their A17 and M3 SoCs.
[17] Zen 5 CCDs are fabricated on TSMC's N4X node which is intended to accommodate higher frequencies for high-performance computing (HPC) applications.
N4X maintains IP compatibility with N4P and offers a 6% frequency gain over N4P at the same power but comes with the trade-off of moderate leakage.
[19] Compared to the N5 node used to produce Zen 4 CCDs, N4X can enable up to 15% higher frequencies while running at 1.2V.
The monolithic die used by "Strix Point" mobile processors, fabricated on TSMC's lower power N4P node, measures 232.5mm2 in area.
[24] 28 years after it was first proposed in academic research, AMD's Zen 5 architecture became the first microarchitecture to fully implement two-ahead branch prediction.
The wider front end in the Zen 5 architecture necessitates larger caches and higher memory bandwidth in order to keep the cores fed with data.
[27] This allows for increased core frequency compared to previous generation 3D V-Cache implementations which were sensitive to higher voltages.
Strix Point features a 3rd gen Ryzen AI engine based on XDNA 2, providing up to 50 TOPS of neural processing unit performance.
[42] Common features of Ryzen AI 300 notebook APUs: Alongside Granite Ridge desktop and Strix Point mobile processors, the Epyc 9005 series of high-performance server processors, codenamed Turin, were also announced at Computex on June 3, 2024.
It uses the same SP5 socket as the previous Epyc 9004 series processors, and will pack up to 128 cores and 256 threads on the top-end model.
