Zen 5 is the name for a CPU microarchitecture by AMD, shown on their roadmap in May 2022,[3] launched for mobile in July 2024 and for desktop in August 2024.[4] It is the successor to Zen 4 and is currently fabricated on TSMC's N4P process.[5] Zen 5 is also planned to be fabricated on the N3E process in the future.[6]
The Zen 5 microarchitecture powers Ryzen 9000 series desktop processors (codenamed "Granite Ridge"), Epyc 9005 server processors (codenamed "Turin"),[7] and Ryzen AI 300 thin and light mobile processors (codenamed "Strix Point").[8]
Background
A roadmap shown during AMD's Financial Analyst Day on June 9, 2022 confirmed that Zen 5 and Zen 5c would be launching in 3nm and 4nm variants in 2024.[9] The earliest details on the Zen 5 architecture promised a "re-pipelined front end and wide issue" with "integrated AI and Machine Learning optimizations".
During AMD's Q4 2023 earnings call on January 30, 2024, AMD CEO Lisa Su stated that Zen 5 products would be "coming in the second half of the year".[10]
Architecture
Zen 5 is a ground-up redesign of Zen 4 with a wider front-end, increased floating point throughput and more accurate branch prediction.[11]
Fabrication process
Zen 5 was designed with both 4nm and 3nm processes in mind. This acted as an insurance policy for AMD in the event that TSMC's mass production of its N3 nodes were to face delays, significant wafer defect issues or capacity issues. One industry analyst estimated early N3 wafer yields to be at 55% while others estimated yields to be similar to those of N5 at between 60-80%.[12][13] Additionally, Apple, as TSMC's largest customer, is given priority access to the latest process nodes. In 2022, Apple was responsible for 23% of TSMC's $72 billion in total revenue.[14] 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.[15] Zen 5 Processors will continue to use the TSMC N6 node for the I/O die fabrication.[16]
Zen 5's CCDs are fabricated on TSMC's N4P node.[5] N4P offers a 11% more performance, 22% less power at the same performance and 6% density improvement over N5 which was used to produce Zen 4 CCDs. Zen 5c CCDs for Turin Dense server processors are fabricated on TSMC's N3 node.
Cache and instructions
The L1 cache per core is increased from 64 KiB to 80 KiB per core. The L1 instruction cache remains the same at 32 KiB but the L1 data cache is increased from 32 KiB to 48 KiB per core. Furthermore, the bandwidth of the L1 data cache for 512-bit floating point unit pipes has also been doubled. Zen 5 contains 6 Arithmetic Logic Units (ALUs), up from 4 ALUs in prior Zen architectures. A greater number of ALUs that handle common integer operations can increase per-cycle scalar integer throughput by 50%.[17]
Zen 4 introduced AVX-512 instructions. AVX-512 capabilities have been expanded with Zen 5 with a doubling of the floating point pipe width to 512-bit. Additionally, there is greater bfloat16
throughput which is beneficial for AI workloads.
Other improvements
Other features and improvements, compared to Zen 4, include:
- A ~16% IPC uplift on average, claimed by AMD.[18]
- Memory speeds up to DDR5-5600 and LPDDR5X-7500 are officially supported.[19]
- Infinity Fabric clock (FCLK) has been increased to 2400 MHz.[20]
- New 2-ahead branch predictor[21]
