Core Count and Architecture
The EPYC 9654 boasts an impressive 96 cores, while the Threadripper 5995WX features 64 cores. Both processors are based on AMD’s Zen 3 architecture, offering significant performance improvements over previous generations. However, the EPYC 9654’s higher core count gives it an edge in heavily multithreaded applications that can effectively utilize all available cores.
Clock Speeds and Boost Technology
The Threadripper 5995WX has a higher base clock speed of 2.7 GHz compared to the EPYC 9654’s 2.4 GHz. However, the EPYC 9654 features AMD’s Precision Boost 2 technology, which allows it to boost up to 3.2 GHz, while the Threadripper 5995WX can boost up to 4.5 GHz. This means that the Threadripper 5995WX will deliver better performance in single-threaded or lightly threaded workloads.
Cache Sizes
The EPYC 9654 has a massive 768MB of L3 cache, while the Threadripper 5995WX has 288MB. This larger cache size gives the EPYC 9654 an advantage in applications that require frequent access to large datasets, such as data analysis and machine learning.
Memory Support
Both processors support DDR4 memory, with the EPYC 9654 supporting up to 2TB of memory and the Threadripper 5995WX supporting up to 256GB. However, the EPYC 9654 features eight memory channels, while the Threadripper 5995WX has four. This gives the EPYC 9654 better memory bandwidth, which can improve performance in memory-intensive workloads.
I/O Capabilities
The EPYC 9654 and Threadripper 5995WX offer a wide range of I/O options. Both processors support PCIe 4.0, with the EPYC 9654 featuring 128 lanes and the Threadripper 5995WX featuring 88 lanes. Additionally, the EPYC 9654 supports up to 128 PCIe 3.0 lanes, while the Threadripper 5995WX supports up to 16.
Power Consumption and Cooling
The EPYC 9654 has a TDP of 280W, while the Threadripper 5995WX has a TDP of 280W. Both processors require powerful cooling solutions to maintain optimal performance. However, the EPYC 9654’s larger core count and higher memory bandwidth may result in higher power consumption under heavy loads.
Suitability for Different Workloads
The EPYC 9654 is ideally suited for highly parallel workloads that can take advantage of its massive core count and large cache size. This includes scientific simulations, data analysis, machine learning, and rendering. The Threadripper 5995WX, with its higher clock speeds and single-core performance, is better suited for applications that require high performance in single-threaded or lightly threaded workloads, such as gaming, video editing, and CAD.
Recommendations
The AMD EPYC 9654 and Threadripper 5995WX are both exceptional workstation processors with their own unique strengths. The EPYC 9654 excels in heavily multithreaded workloads, while the Threadripper 5995WX shines in single-threaded and lightly threaded applications. Ultimately, the best choice for you will depend on the specific workloads you intend to run.
