AMD EPYC 7513 vs Intel Xeon w7-2595X Comparison

The Intel Xeon w7-2595X and AMD EPYC 7513 are both 97th-percentile server/workstation processors, but they achieve that standing through very different strategies. The Xeon w7-2595X, built on Sapphire Rapids, wins 12 of the 17 head-to-head benchmarks, while the EPYC 7513, a Zen 3 Milan part, takes the remaining 5. The data shows a clear split: Intel dominates in single-threaded and floating-point workloads, while AMD counters in encryption, prime-number finding, and physics simulation. The Xeon w7-2595X posts an average benchmark score of 108663 against the EPYC's 102244, a gap of roughly 6.3% overall, but the per-test deltas range from a razor-thin 2.3% to a massive 50.2% swing, so the "right" choice depends entirely on the workload mix.

Head-to-Head Benchmarks

The most lopsided victory for the Intel Xeon w7-2595X comes in the PassMark single-thread test, where it scores 3723 against the EPYC 7513's 2479 — a 50.2% advantage. This is not a marginal win; it is a generational gap in per-core performance. The same pattern appears across the entire Cinebench suite. In Cinebench R23 single-core, the Xeon scores 7745 versus 7119, an 8.8% lead, and that exact 8.8% delta repeats in Cinebench R15 and R20 for both single-core and multi-core tests. The multi-core scores tell a similar story: 54863 versus 50431 in R23, 23042 versus 21181 in R20, and 5530 versus 5083 in R15. Intel wins all six Cinebench tests with the same 8.8% margin, which suggests a consistent architectural efficiency advantage rather than a clock-speed-only effect.

Beyond rendering, the Xeon w7-2595X shows dominant floating-point performance. In PassMark floating-point math, it scores 202906 against 151713, a 33.7% improvement. Extended instruction set performance is even more decisive: 77613 versus 56451, a 37.5% lead. Data compression also favors Intel, with 983046 versus 932240, a 5.4% win. The multithread benchmark goes to Intel at 64628 versus 59331, an 8.9% margin. These results paint a picture of a chip that is simply faster per clock and per core, despite having fewer cores and threads.

However, the AMD EPYC 7513 is not without its own decisive victories. The largest win for AMD is in PassMark physics, where it scores 5118 against Intel's 2759 — a 46.1% advantage. This is a staggering reversal, indicating that the Zen 3 architecture's handling of physics simulation workloads is fundamentally superior. The EPYC also crushes the Xeon in data encryption: 63628 versus 49782, a 21.8% lead. In the find-prime-numbers test, AMD scores 380 versus 259, a 31.8% win. Integer math goes to AMD by a smaller margin, 272145 versus 261384, a 4% edge. Random string sorting is nearly a tie, with AMD ahead at 104660 versus 102230, a 2.3% difference. Each of these AMD wins is substantial in its own right, and together they show that the EPYC is not merely a high-core-count brute — it has genuine specialized strengths.

FAQ

Q: Which processor has more cores and threads?

A: The AMD EPYC 7513 has 32 cores and 64 threads, compared to the Intel Xeon w7-2595X's 26 cores and 52 threads. Despite having 6 fewer cores and 12 fewer threads, the Xeon still wins the majority of multi-threaded benchmarks.

Q: How does the memory bandwidth compare between the two?

A: The AMD EPYC 7513 has higher theoretical memory bandwidth at 204.8 GB/s over an eight-channel DDR4 bus, versus the Intel Xeon w7-2595X's 153.6 GB/s over a quad-channel DDR5 bus. The EPYC also supports DDR4 memory, while the Xeon uses DDR5.

The Verdict

The Intel Xeon w7-2595X is the clear choice for anyone prioritizing raw single-threaded performance, floating-point math, and extended instruction set workloads. Its 50.2% lead in single-thread PassMark and 37.5% lead in extended instructions are not minor edges — they are workload-defining advantages for applications that cannot parallelize perfectly. The Xeon also wins every Cinebench test and the PassMark multithread test, proving that its 26-core count is sufficient to outpace the EPYC's 32 cores in general rendering and productivity tasks. For software development, data compression, and scientific computing that relies on floating-point operations, the Xeon w7-2595X is the data-backed winner.

The AMD EPYC 7513 is the better pick for workloads that match its specific strengths. The 46.1% physics benchmark lead and 21.8% encryption advantage are substantial, making it the superior choice for cryptography, physics simulation, and integer-heavy integer math tasks. Its 32-core, 64-thread configuration also provides more parallel headroom for heavily threaded workloads if the software scales perfectly, even though the benchmark data shows the Xeon holding the edge in Cinebench. The EPYC also offers higher memory bandwidth at 204.8 GB/s, which could benefit memory-bound applications despite the DDR4 limitation.

Neither chip is universally superior. The Xeon w7-2595X wins 12 benchmarks; the EPYC 7513 wins 5. But the EPYC's wins are in highly specialized domains, while the Xeon's wins span general compute, rendering, and single-threaded responsiveness. A buyer would choose the EPYC 7513 for encryption, physics, or integer-heavy server workloads, and the Xeon w7-2595X for almost everything else, especially any single-threaded or floating-point work.

Specification Differences

The two processors differ in nearly every core specification. The Intel Xeon w7-2595X has 26 cores and 52 threads, while the AMD EPYC 7513 has 32 cores and 64 threads — a 6-core and 12-thread advantage for AMD. Clock speeds also diverge sharply: the Xeon has a base clock of 2.80 GHz and a boost clock of 4.80 GHz, whereas the EPYC runs at 2.60 GHz base and 3.65 GHz boost. This 1.15 GHz boost advantage for Intel is the likely driver of its single-thread dominance.

Power and socket are completely different. The Xeon w7-2595X has a TDP of 250 watts and uses Intel Socket 4677, while the EPYC 7513 has a lower TDP of 200 watts and uses AMD Socket SP3. The Xeon supports DDR5 memory over a quad-channel bus with 153.6 GB/s bandwidth, while the EPYC supports DDR4 over an eight-channel bus with 204.8 GB/s bandwidth. PCIe generations also differ: the Xeon offers Gen 5 with 64 lanes (CPU only), while the EPYC offers Gen 4 with 128 lanes (CPU only).

Cache hierarchies are distinct as well. The Xeon w7-2595X has 80 KB of L1 per core, 2 MB of L2 per core, and 48.75 MB of L3 cache. The EPYC 7513 has 64 KB of L1 per core, 512 KB of L2 per core, and a much larger 128 MB of shared L3 cache. The EPYC also has an unlocked multiplier? No, it is locked; the Xeon w7-2595X has an unlocked multiplier. The release dates are 2024-08-23 for the Xeon and 2021-03-14 for the EPYC. The launch MSRP for the Xeon is $2039, and for the EPYC it is $2840.

Architecture Differences

The architectural divide starts with the manufacturing process. The Intel Xeon w7-2595X is built on a 10 nm node at Intel's foundry, using the Sapphire Rapids codename from the Xeon W generation. The AMD EPYC 7513 uses TSMC's 7 nm process, based on the Zen 3 architecture and codenamed Milan, belonging to the EPYC 7003 series. The EPYC is a chiplet design, with 33,200 million transistors spread across 8 dies of 81 mm² each; the Xeon's transistor count and die size are not specified in the data.

Cache architecture is a major differentiator. The EPYC's 128 MB of shared L3 cache is more than 2.5 times larger than the Xeon's 48.75 MB. This massive L3 pool is typical of AMD's chiplet approach, where each CCD has its own 32 MB slice. The Xeon's smaller L3 is offset by its much larger L2 cache at 2 MB per core versus 512 KB per core on the EPYC, which helps feed the high boost clocks.

Memory architecture also reflects different design philosophies. The EPYC's eight-channel DDR4 controller provides higher peak bandwidth at 204.8 GB/s, while the Xeon's quad-channel DDR5 controller provides lower bandwidth at 153.6 GB/s but with the newer memory standard. The EPYC also supports more PCIe lanes at Gen 4 (128 lanes) versus the Xeon's Gen 5 (64 lanes), trading raw lane count for newer generation speed.

The feature set further separates the two. The Xeon w7-2595X has an unlocked multiplier, enabling overclocking, while the EPYC 7513 is locked. Both support ECC memory. The Xeon is a 2024 release with a part number of SRN4C; the EPYC launched in 2021 with part number 100-000000334100-100000334WOF. The Xeon does not have integrated graphics; the EPYC's integrated graphics field is not specified. These architectural choices explain the benchmark results: Intel bets on high clocks, large per-core caches, and DDR5, while AMD bets on more cores, a massive shared L3, and higher memory bandwidth.
