AMD has been at the forefront of CPU innovation for years, consistently pushing the envelope in both consumer and enterprise markets. The recent unveiling of the 4th Gen AMD EPYC 97X4 processors, previously codenamed AMD Bergamo, and Genoa-X has reignited the discussion about the future of computing power.

AMD Bergamo: The Future of Cloud Computing

In June, AMD made waves with the announcement of its AMD Bergamo CPU Socket. Designed to cater to specialized workloads for businesses, these processors provide impressive vCPU density and increased performance. Particularly targeted at AI applications and cloud-based operations, the AMD EPYC 97X4 processors are a powerhouse, offering up to 3.7x better performance for key cloud-native workloads compared to competitors like Ampere.

The Zen 4c Microarchitecture: A New Dawn

The Zen 4c microarchitecture in Bergamo is revolutionary, retaining Zen 4's design but with significant improvements. It's around 35.4% smaller compared to Zen 4 cores, and the feat is achieved through various innovative techniques such as:

  • Reducing Boost Clock Targets: Lowering from 3.70 GHz to 3.10 GHz to allow tighter packing of signal pathways.

  • Packing Logic Closer Together: Though it made debugging more challenging, it significantly reduced die size.

  • Using Denser 6T Dual-Port SRAM Cells: This resulted in smaller SRAM areas while retaining similar cache sizes.

  • Removing Through-Silicon Vias (TSVs): An additional method to save silicon.

These modifications were just the beginning. The Bergamo processor's design is based on eight Vindhya core complex dies (CCDs) with 16 Zen 4c cores each, which impacts clock speed potential while achieving the same 360W – 400W power envelope as Genoa.

Technical Insights

With 128 cores, AMD Bergamo is a true behemoth capable of delivering incredible throughput. Some of the key specifications are:

  • 9754: 128 Cores, 256 Threads, 360W TDP, 2.25 GHz Base, 3.10 GHz Boost, 256 MB L3 Cache

  • 9754S: 128 Cores, 128 Threads, 360W TDP, 2.25 GHz Base, 3.10 GHz Boost, 256 MB L3 Cache

  • 9734: 112 Cores, 224 Threads, 320W TDP, 2.20 GHz Base, 3.00 GHz Boost, 256 MB L3 Cache

AMD Genoa-X: Pioneering Technical Computing

AMD Genoa-X, equipped with 3D V-Cache and codenamed as the leading x86 server CPU for technical computing, is setting benchmarks in the industry. These processors, tailored for demanding workloads such as computational fluid dynamics and electronic design automation, showcase AMD's commitment to aligning its product roadmap to customer needs.

Technical Insights

  • 9684X: 96 Cores, 192 Threads, 400W TDP, 2.55 GHz Base, 3.70 GHz Boost, 1,152 MB L3 Cache

  • 9384X: 32 Cores, 64 Threads, 320W TDP, 3.10 GHz Base, 3.90 GHz Boost, 768 MB L3 Cache

  • 9184X: 16 Cores, 32 Threads, 320W TDP, 3.55 GHz Base, 4.20 GHz Boost, 768 MB L3 Cache

Performance Benchmarks

Storage Review conducted extensive benchmarks to assess the performance of AMD Bergamo and Genoa-X CPUs. They ran various tests like Cinebench R23, y-cruncher, Blender, and Geekbench, reflecting the capabilities of these CPUs in rendering, number crunching, and general processing.


  • Cinebench R23: 96 Core Genoa-X shined with better single-core performance.

  • y-cruncher: Genoa processors showed impressive computational prowess.

  • Blender Benchmarks: The raw power of 512 threads (quad-socket Bergamo) topped the charts.

  • Geekbench 6 CPU: Balanced performance in both single-core and multi-core operations.

The full and extensive review is well worth reading for the details.

AMD Bergamo for AI

AMD's Bergamo is also paving the way for AI, featuring inference engines from top-tier vendors. The benchmark scores in real-world scenarios are promising, reflecting the superior performance in tasks like object detection and image enhancement.

Final Thoughts

AMD's 4th Gen EPYC processors, Bergamo and Genoa-X, are monumental steps towards advanced ultra-high core count computing. Their capability in handling data and compute-intensive tasks, the efficiency of AMD’s chiplet design, and the alignment with the demands of AI and cloud-native applications set them as the new benchmarks in rack density and computing prowess.

As we travel deeper into this new era of computing, it's evident that AMD is not just meeting the expectations but exceeding them, defining what the future of CPU technology can and should be. We can only hope that Intel will come out swinging next, because when the big boys battle it out, consumers always win.
