其中大家關心的Zen4.Zen5.RDNA3有進一步的資訊揭露:
“Zen 4” CPU core expected to power the world’s first high-performance 5nm
x86 CPUs later this year. “Zen 4” is expected to increase IPC 8%-10%1 and
deliver more than a 25% increase in performance-per-watt2 and 35% overall
performance increase compared to “Zen 3” when running desktop applications3.
Zen4將會有8~10%的IPC增加，25%的效能/功耗改善，35%的表現增加。
其中最讓人好奇的是”35%表現增加”是怎麼測的，畢竟IPC加上狂飆的頻率好像也還算不
到35%表現增加。
在Footnote上有說明: Single-thread performance evaluated with Cinebench R23
1T. AMD Ryzen 9 5950X System: ASUS ROG Crosshair VIII Hero X570, 2x8
DDR4-3600C16. AMD Ryzen 7000 Series: AMD Reference X670 Motherboard, Ryzen
7000 Series 16-core pre-production processor sample, 2x16GB DDR5-6000CL30.
All systems configured with Radeon™ RX 6950XT GPU (driver: 22.10 Prime),
Windows 11 Build 22000.593, Samsung 980 Pro 1TB SSD, Asetek 280MM liquid
cooler.
是拿16核的測試品和5950X對比，測試Cinebench R23 single thread，同時記憶體用的
是DDR5-6000CL30。
根據CPU Monkey，5950X目前的Cinebench R23 1T分數是1644，乘上1.35會得到2219
(12900KS是2082，12900K是1997)
“Zen 5” CPU core planned for 2024, which is built from the ground up to
deliver performance and efficiency leadership across a broad range of
workloads and features and includes optimizations for AI and machine learning.
Zen5預計在2024年推出，值得注意的是強調的重點是加強AI和machine learning。
AMD RDNA™ 3 gaming architecture that combines a chiplet design, next
generation AMD Infinity Cache™ technology, leading-edge 5nm manufacturing
technology, and other enhancements to deliver more than 50% greater
performance-per-watt compared to the prior generation4.
RDNA3將採用chiplet設計，5nm製造，會比RDN2提高50%的效能/功耗改善
