AMD EPYC 7443P vs Intel Xeon w7-2575X Comparison

The Intel Xeon w7-2575X and AMD EPYC 7443P both land in the 96th percentile of all CPUs in the database, yet they achieve that standing through completely different strengths. The AMD EPYC 7443P wins 13 of the 17 recorded head-to-head benchmarks, dominating in rendering, encryption, and physics tasks, while the Intel Xeon w7-2575X takes 4 wins with decisive margins in floating-point math, extended instructions, and single-threaded PassMark tests. The result is a clear split: AMD leads in threaded production workloads, while Intel counters with specialized compute and per-core speed.

Where Each One Wins

The AMD EPYC 7443P is the overall performance leader in this comparison. Across the Cinebench suite, the EPYC wins every iteration from R15 to R23, both single-core and multi-core, with a consistent 8.6% advantage over the Xeon. In multi-threaded Cinebench R23, the EPYC scores 48433 against the Xeon’s 44277, a gap that reflects its additional cores and threads. This pattern repeats in PassMark multithread, where the EPYC scores 56981 versus 52091, again an 8.6% lead. The EPYC also wins PassMark integer math, data compression, data encryption, and random string sorting. Its most dramatic win is in the physics test, where it scores 4748 against the Xeon’s 2222, a 53.2% advantage. The encryption result is similarly lopsided: 57263 versus 39295, a 31.4% margin. These are workloads that scale with core count and memory bandwidth, and the EPYC has both.

The Intel Xeon w7-2575X wins fewer tests but wins them by large margins. Its floating-point math score of 171427 is 31.9% ahead of the EPYC’s 129932. The extended instructions test shows a 29.6% lead, with the Xeon scoring 62498 versus 48213. In PassMark single-thread, the Xeon scores 3300 against the EPYC’s 2907, a 13.5% advantage. These wins point to a processor with higher per-core efficiency and stronger SIMD or instruction-level throughput. The data suggests the Xeon is the better choice for workloads dominated by floating-point calculations, vectorized code, or lightly threaded tasks that require maximum single-core responsiveness.

Architecture Differences

The two processors come from different design philosophies. The AMD EPYC 7443P is built on TSMC’s 7 nm process with the Zen 3 architecture, codenamed Milan. It packs 24 cores and 48 threads, with a base clock of 2.85 GHz and a boost clock of 4.00 GHz. The chip contains 16,600 million transistors across four dies, each 81 mm² in size. Its cache layout favors capacity: 64 KB of L1 per core, 512 KB of L2 per core, and a large 128 MB shared L3 pool. Memory support is DDR4 over an eight-channel bus, delivering 204.8 GB/s of bandwidth. The EPYC also offers PCIe Gen 4 with 128 lanes from the CPU, making it a massive I/O platform. Its TDP is 200 W, and it uses AMD Socket SP3.

The Intel Xeon w7-2575X is built on Intel’s 10 nm process with the Sapphire Rapids architecture. It has 22 cores and 44 threads, fewer than the EPYC, with a base clock of 3.00 GHz and a higher boost clock of 4.80 GHz. The cache is structured differently: 80 KB of L1 per core, 2 MB of L2 per core, and 45 MB of L3. Memory support is DDR5 over a quad-channel bus, yielding 153.6 GB/s of bandwidth, which is lower than the EPYC’s figure. The Xeon supports PCIe Gen 5 with 64 lanes from the CPU. It carries a 250 W TDP and uses Intel Socket 4677. The Xeon has an unlocked multiplier, while the EPYC does not. The EPYC’s shared L3 cache is nearly three times larger than the Xeon’s, and its memory bandwidth advantage is substantial, while the Xeon counters with newer memory technology, a higher boost clock, and newer PCIe generation.

Head-to-Head Benchmarks

The Cinebench suite is entirely one-sided. In Cinebench R23 multi-core, the EPYC scores 48433 against 44277, an 8.6% lead. The single-core R23 result also favors the EPYC: 6837 versus 6250, again 8.6%. The same margin appears in R20 multi-core (20341 versus 18596) and R20 single-core (2871 versus 2625). R15 follows the pattern with 4881 versus 4463 in multi-core and 689 versus 630 in single-core. No Cinebench test goes to Intel.

PassMark tells a more varied story. The EPYC wins data compression with 820859 versus 789817, a 3.8% margin. It wins data encryption by a much wider 31.4%, scoring 57263 against 39295. The EPYC also takes find prime numbers with 410 versus 218, a 46.8% blowout. Integer math goes to the EPYC at 232632 versus 219924, a 5.5% lead. Multithread goes to the EPYC at 56981 versus 52091, an 8.6% margin. Physics is the EPYC’s largest win: 4748 versus 2222, a 53.2% gap. Random string sorting also favors the EPYC at 95581 versus 77986, an 18.4% advantage.

The Xeon’s wins are concentrated but emphatic. Floating-point math goes to Intel at 171427 versus 129932, a 31.9% advantage. Extended instructions favor Intel at 62498 versus 48213, a 29.6% lead. Both single-thread PassMark entries show the same result: Intel at 3300 versus 2907, a 13.5% margin. These four wins demonstrate that the Xeon is not merely competitive in its niche; it is decisively ahead in those specific workloads.

Specification Differences

The AMD EPYC 7443P has 24 cores and 48 threads, while the Intel Xeon w7-2575X has 22 cores and 44 threads. The Xeon has a base clock of 3.00 GHz and a boost clock of 4.80 GHz, against the EPYC’s 2.85 GHz base and 4.00 GHz boost. TDP differs as well: the Xeon is rated at 250 W, the EPYC at 200 W. The Xeon uses Intel Socket 4677, the EPYC uses AMD Socket SP3. The Xeon is built on Intel’s 10 nm process with Sapphire Rapids architecture, while the EPYC is built on TSMC’s 7 nm process with Zen 3 Milan architecture. The EPYC has 16,600 million transistors across 4x 81 mm² dies; the Xeon lists no transistor or die size figure in the database. Cache layouts diverge sharply: the Xeon has 80 KB L1 per core, 2 MB L2 per core, and 45 MB L3, while the EPYC has 64 KB L1 per core, 512 KB L2 per core, and 128 MB shared L3. The Xeon supports DDR5 memory over a quad-channel bus with 153.6 GB/s bandwidth; the EPYC supports DDR4 over an eight-channel bus with 204.8 GB/s. PCIe also differs: the Xeon offers Gen 5 with 64 lanes, the EPYC offers Gen 4 with 128 lanes. The Xeon has an unlocked multiplier; the EPYC does not. Both support ECC memory. The launch MSRP for the Xeon is $1689; the EPYC’s launch MSRP is $1337.

The Verdict

The benchmark data points to a straightforward conclusion for all-core workloads: the AMD EPYC 7443P is the stronger processor. It wins every Cinebench test, every PassMark multithread test, and the majority of PassMark compute tests. Its 24 cores, 48 threads, 128 MB shared L3, and 204.8 GB/s memory bandwidth give it a structural advantage that shows up consistently across rendering, encryption, compression, and integer math. The 53.1% lead in physics and 31.4% lead in encryption are the kind of margins that matter in simulation and security-heavy server environments. The Xeon simply cannot close the gap on core-count-dependent tasks.

The Intel Xeon w7-2575X is the pick for specific compute patterns. Its 31.9% win in floating-point math and 29.6% win in extended instructions show a clear edge in vectorized and floating-point-heavy code. Its 13.5% single-thread PassMark lead also makes it the better option for lightly threaded responsiveness. The Xeon also brings PCIe Gen 5 and DDR5 support, which are newer standards than the EPYC’s PCIe Gen 4 and DDR4. Buyers prioritizing per-core speed, floating-point throughput, or newer memory and I/O generations should favor the Xeon. Buyers prioritizing raw multi-core throughput, memory bandwidth, or encryption and physics performance should choose the EPYC. The data does not support a single universal winner; it supports two distinct profiles for two distinct sets of workloads.
