AMD EPYC 9275F vs Intel Xeon w7-3565X Comparison

The Verdict

The recorded data presents a clear split. The AMD EPYC 9275F wins 16 of the 17 head-to-head benchmark comparisons, with an average benchmark score of 133174 against Intel's 118307. That places the EPYC 9275F roughly 12.6% ahead in overall average score. The Intel Xeon w7-3565X secures only a single win, in floating-point math, by 7.7%. For any workload that leans on Cinebench rendering, data compression, encryption, or integer math, the AMD part is the definitive choice. The Intel part is targeted at a narrow set of floating-point-heavy tasks. However, the Xeon w7-3565X does come with a lower launch MSRP of $2689 compared to the EPYC's $3439, and it has an unlocked multiplier for user overclocking. The data suggests that for general server or workstation compute, the AMD EPYC 9275F is the stronger performer despite its higher launch price. The Intel Xeon w7-3565X should be selected only when the floating-point advantage is more valuable than the AMD's dominance elsewhere.

Architecture Differences

The fundamental architectural split is stark. The AMD EPYC 9275F uses the Zen 5 architecture on a 4 nm process from TSMC, with a codename of Turin. The Intel Xeon w7-3565X is built on the Sapphire Rapids codename, using a 10 nm process from Intel. This process difference is significant; the AMD part is manufactured on a more advanced node. The physical die configurations differ as well. The AMD EPYC 9275F is reported with a die size of 8x 70.6 mm², while the Intel Xeon w7-3565X has a die size of 4x 477 mm². The L3 cache sizes are drastically different. The EPYC 9275F has a massive 256 MB of shared L3 cache, while the Xeon w7-3565X has an 82.5 MB L3 cache. Both have the same 80 KB L1 cache per core, but the L2 cache differs: 1 MB per core for AMD, 2 MB per core for Intel. The AMD platform uses a twelve-channel memory bus, while Intel uses an eight-channel bus. Both support DDR5 memory and ECC. In terms of PCIe, the EPYC 9275F offers 128 Gen 5 lanes (CPU only), while the Xeon w7-3565X offers 112 Gen 5 lanes (CPU only). The AMD EPYC 9275F also has a higher base clock of 4.10 GHz versus Intel's 2.50 GHz, though both have the same 4.80 GHz boost clock. The EPYC 9275F also has a lower TDP of 320 watts compared to 335 watts for the Xeon. The Intel Xeon w7-3565X is the only one with an unlocked multiplier, allowing for overclocking, which the AMD part cannot do.

Head-to-Head Benchmarks

The most consistent pattern is in Cinebench tests. Across all six Cinebench R15, R20, and R23 tests (single and multi-core), the AMD EPYC 9275F wins with a uniform 19.8% margin. This is a strong indicator of raw CPU rendering performance. For example, in Cinebench R23 multi-core, the EPYC scores 71,927 points, decisively ahead of the Xeon's 60,045 points. In single-core R23, the EPYC's 10,154 points beat the Xeon's 8,477 by the same 19.8%.

The Passmark tests show a wider range of deltas. The largest margin is in the Physics test, where the EPYC 9275F scores 12,089 against the Xeon's 4,254, a 184.2% difference. The Find Prime Numbers test also shows a massive gap, with the EPYC scoring 991 versus the Xeon's 398, a 149% advantage. The Random String Sorting test shows a 29.9% win for the EPYC (144,037 vs 110,848). The Integer Math test sees the EPYC ahead by 13.8% (317,777 vs 279,202). Data Compression shows a 12.7% lead (1,212,560 vs 1,075,602), and Data Encryption shows a 14.6% lead (62,664 vs 54,676). The Extended Instructions test shows a 10.5% advantage for the EPYC (94,889 vs 85,856). In the Multithread test, the EPYC wins by 19.8% (84,620 vs 70,642). The Single Thread test shows an 11.8% lead for the EPYC (3,810 vs 3,407). The only Intel win is in Floating Point Math, where the Xeon w7-3565X scores 218,720 versus the EPYC's 201,888, a 7.7% advantage for Intel. The data shows that the EPYC 9275F dominates almost every category, but the Intel part has a specific edge in floating-point operations.

Specification Differences

The two processors differ in several key specifications. The AMD EPYC 9275F has 24 cores and 48 threads, while the Intel Xeon w7-3565X has 32 cores and 64 threads. Despite having fewer cores, the EPYC 9275F demonstrates superior performance in most multi-threaded benchmarks, which indicates a higher per-core throughput. The base clock is a major difference, with the EPYC running at 4.10 GHz versus the Xeon's 2.50 GHz. The boost clock is identical at 4.80 GHz. The EPYC has a smaller L2 cache per core (1 MB vs 2 MB), but a much larger L3 cache (256 MB vs 82.5 MB). The memory bus width is a differentiator: twelve channels for AMD versus eight for Intel. The memory bandwidth is 576.0 GB/s for the EPYC versus 307.2 GB/s for the Xeon, a significant factor in memory-intensive workloads. The PCIe lane count also differs, with AMD offering 128 lanes versus Intel's 112 lanes. The process node and die size are different, as detailed previously. The EPYC 9275F has a launch MSRP of $3439, while the Xeon w7-3565X has a launch MSRP of $2689. The Intel part has an unlocked multiplier; the AMD part does not. The release dates differ, with the Xeon releasing on 2024-08-23 and the EPYC on 2024-10-09. The EPYC is listed with the part number 100-000001144, and the Xeon with SRN73.

Where Each One Wins

The AMD EPYC 9275F wins in 16 of the 17 benchmarks. Its strengths are clearly in compute-heavy workloads that benefit from high clock speeds, a large L3 cache, and high memory bandwidth. The data shows it is the better choice for Cinebench rendering, Passmark multithreading, integer math, data compression, encryption, and physics simulations. The 184.2% advantage in physics and the 149% advantage in prime number finding are substantial. The consistent 19.8% lead across all Cinebench tests indicates a strong performance per core, which is particularly notable given that the Intel part has more cores. The EPYC 9275F also has a wider memory bus (12-channel) and double the memory bandwidth, which likely contributes to its wins in memory-sensitive tasks like random string sorting and data compression. Its 128 PCIe lanes also make it a strong choice for systems with many high-speed peripherals.

The Intel Xeon w7-3565X has a single win in Floating Point Math, indicating a specific strength in workloads that rely heavily on floating-point calculations. The data does not show it winning any other test. It has more cores (32 vs 24) but a lower base clock, which does not translate into a win in the recorded benchmarks. Its primary advantages are the unlocked multiplier, allowing for overclocking, and a lower launch MSRP of $2689. However, the benchmark data does not support a general performance recommendation for the Intel part, except for those specific floating-point tasks. The large L2 cache per core (2 MB) might help in some situations, but the recorded data does not demonstrate that it overcomes the AMD part's other advantages. In summary, the Intel Xeon w7-3565X is the choice for floating-point heavy applications and for users who take advantage of the unlocked multiplier, while the AMD EPYC 9275F is the superior choice for the vast majority of other server and workstation workloads.
