AMD EPYC 9755 “Turin” CPU: Zen 5 Architecture Delivers Record Performance

AMD’s EPYC 9755 “Turin” CPU, built on the Zen 5 core architecture, has recently undergone benchmark testing and achieved remarkable results in the CPU-z benchmark. Let’s dive into the details of this powerful processor.

The EPYC 9755 Specifications

The EPYC 9755 is part of the 5th Gen EPYC family, codenamed Turin. Here are the key specifications:

• Cores and Threads: Featuring an impressive 128 cores and 256 threads, the EPYC 9755 offers substantial parallel processing capabilities.
• Clock Speeds: The base clock speed is 2.70 GHz, with a boost clock of up to 4.10 GHz. This represents an 11% increase in clock speeds compared to its predecessor.
• Cache: The CPU boasts a massive cache pool, including 512 MB of L3 cache, 128 MB of L2 cache, and 10 MB of L1 cache. In total, this amounts to 650 MB of cache—a 31% increase over the previous EPYC flagship, the EPYC 9654 (based on Zen 4 architecture).

Zen 5 vs. Zen 4

Let’s compare the EPYC 9755 with its predecessor, the EPYC 9654:

• EPYC 9755 “Zen 5”:
  • 16 CCDs (Core Chiplets) with 8 cores per CCD (128 cores in total)
  • 4 MB L3 cache per core (32 MB per CCD)
  • 1 MB L2 cache per core (8 MB per CCD)
  • 80 KB L1 cache per core (640 KB per CCD)
  • Total cache: 650 MB
• EPYC 9654 “Zen 4”:
  • 12 CCDs with 8 cores per CCD (96 cores in total)
  • 4 MB L3 cache per core (32 MB per CCD)
  • 1 MB L2 cache per core (8 MB per CCD)
  • 64 KB L1 cache per core (512 KB per CCD)
  • Total cache: 496 MB

Benchmark Results

The EPYC 9755 was put through its paces in the CPU-z benchmark. Despite its lower single-core clocks, it achieved an impressive single-core score of 653.7 points. However, the real standout performance came in the multi-core test, where it scored a phenomenal 108,093 points.

Multi-Thread Score Comparison:

• EPYC 9755 (128 Core / Turin Zen 5): 108,093 points
• EPYC 9654 (96 Core / Genoa Zen 4): 95,002 points
• EPYC 9754 (128 Core / Genoa Zen 4C): 68,803 points

What’s Next?

While we can’t confirm whether this benchmark was conducted in a single-socket or dual-socket configuration, the EPYC 9755’s 108K score is an impressive feat. It outperforms the fastest EPYC 9654 score by 14%. Keep in mind that this might be an early engineering sample, and we can expect even better performance with the final silicon.

Additionally, the EPYC 9755’s performance gives us a glimpse of what to expect from the next-gen Threadripper lineup based on Zen 5 architecture. If EPYC can achieve over 100K points, Threadripper CPUs—with higher clock frequencies and optimizations—could potentially surpass the 120-130K barrier and even touch 150K with overclocking.

In summary, AMD’s Zen 5 offerings are poised to take server and workstation performance to the next level, building upon the success of Zen 4.
