AMD EPYC 8434P vs Intel Xeon 6741P Comparison

The Intel Xeon 6741P and AMD EPYC 8434P present an unusual head-to-head case: two server processors with identical core counts and thread counts, yet benchmark results that diverge dramatically. The database records the Xeon 6741P winning 16 of 17 shared tests, a margin large enough that these two parts, despite matching on paper in cores and threads, sit in different performance tiers. What follows unpacks why, using only the recorded specifications and measurements.

FAQ

Q: Which processor is faster overall?

A: The Intel Xeon 6741P. It leads the AMD EPYC 8434P in 16 of 17 head-to-head benchmarks, with an average benchmark score of 194901 against the EPYC's 146881. The gap is widest in compute-heavy tests such as PassMark physics, where the Xeon scores 13890 versus 4036.

Q: Do these two CPUs have the same core count?

A: Yes. Both are 48-core, 96-thread processors. The performance difference comes from other factors: the Xeon 6741P boosts to 3.80 GHz while the EPYC 8434P tops out at 3.10 GHz, and the Xeon carries twice the shared L3 cache, 288 MB versus 128 MB.

Q: Does the EPYC 8434P win anything?

A: One test. In PassMark data encryption the EPYC scores 97254 against the Xeon's 89746, a lead of roughly 8 percent. It is the sole category where the recorded data favors the AMD part.

Q: Which processor has the lower power rating?

A: The EPYC 8434P, by a wide margin. Its rated TDP is 200 watts versus 300 watts for the Xeon 6741P. That is the single clearest efficiency argument in the AMD column, though the benchmark data does not include performance-per-watt measurements to confirm how it translates in practice.

Q: Are both processors on the same process node?

A: Both are built on 5 nm, but at different foundries. The Xeon 6741P is fabbed by Intel; the EPYC 8434P is fabbed by TSMC.

Q: What platforms do they require?

A: The Xeon 6741P uses Intel Socket 4710 with an eight-channel DDR5 memory bus; the EPYC 8434P uses AMD Socket SP6 with a six-channel DDR5 bus. The two are not interchangeable.

Architecture Differences

The Xeon 6741P belongs to Intel's Granite Rapids generation, specifically Granite Rapids-SP within the Xeon 6 family. The EPYC 8434P is AMD's Siena platform, built on the Zen 4c architecture within the EPYC 8004 series. Both entered the market as active server and workstation parts, but at different times: the EPYC's recorded release date is September 2023 and the Xeon's is February 2025, making the AMD part the older design by a comfortable margin.

Process technology is nominally equal, 5 nm on both sides, but the implementations differ in structure. Intel splits the Xeon 6741P across two dies of 598 mm² each, a dual-die layout carrying a large shared L3 cache of 288 MB. AMD's approach is finer-grained: four chiplets of 73 mm² each, totaling 35500 million transistors, with a smaller 128 MB of shared L3. Per-core cache also favors Intel at every level: 112 KB of L1 and 2 MB of L2 per core on the Xeon, against 64 KB of L1 and 1 MB of L2 per core on the EPYC. For latency-sensitive and cache-hungry workloads, that hierarchy advantage compounds with the clock advantage.

Clock behavior is the other major divergence. Base clocks are identical at 2.50 GHz, but the Xeon 6741P boosts to 3.80 GHz while the EPYC 8434P reaches 3.10 GHz. That headroom difference, combined with the larger cache, explains most of the single-threaded gap visible in the benchmark data. Notably, this holds even though the Zen 4c design is the one optimized for density and efficiency, with its 200-watt rating against the Xeon's 300 watts.

Platform connectivity is not equal either. The Xeon 6741P exposes 136 Gen 5 PCIe lanes from the CPU against 96 on the EPYC 8434P, giving the Intel platform more expansion headroom for accelerators and storage. Memory bandwidth tells a similar story: the eight-channel Intel implementation delivers 409.6 GB/s, while the six-channel AMD bus delivers 230.4 GB/s, nearly a two-to-one advantage for the Xeon. Both support DDR5 with ECC.

Neither processor has integrated graphics, and both ship multiplier-locked, consistent with their server positioning.

The Verdict

The data makes this a straightforward call for raw throughput. The Xeon 6741P sits in the 99th percentile of all CPUs in the database with an average benchmark score of 194901, placing it statistically alongside the AMD EPYC 9335 (194228, within 0.3 percent) and the Intel Xeon 678X (193477, within 0.7 percent). The EPYC 8434P, at the 98th percentile with 146881, clusters with the AMD Ryzen Threadripper PRO 9965WX (147009), AMD Ryzen 9 PRO 9965 (145728), AMD EPYC 7643P (144824), and Intel Xeon w9-3575X (144323). These are both elite parts in absolute terms, but they occupy adjacent rather than identical tiers.

For maximum compute, memory bandwidth, PCIe lanes, and single-threaded responsiveness, the Xeon 6741P is the recorded winner in essentially every category. For deployments where the 200-watt rating matters more than peak performance, the EPYC 8434P is the only one of the two that offers it, and it retains a narrow win in data encryption. The launch MSRP figures, $4421 for the Xeon and $2700 for the EPYC, are recorded in the database for completeness. Nothing in the benchmark data suggests a workload where the EPYC matches the Xeon outside encryption, so the choice reduces to throughput versus the lower power rating.

Head-to-Head Benchmarks

The pattern across the 17 recorded tests is remarkably consistent. Every Cinebench render benchmark falls to the Xeon by the same 51.4 percent margin: R15 multi-core 8624 to 5696, R20 multi-core 35935 to 23736, R23 multi-core 85561 to 56516, and identical 51.4 percent gaps in all three single-core variants (1217 to 804, 5073 to 3350, 12079 to 7978). PassMark multithread repeats the story at 100660 versus 66490, again 51.4 percent in Intel's favor.

The most lopsided results come in integer-adjacent compute. PassMark find prime numbers shows the Xeon at 1242 against 298, more than four times the EPYC's result, and PassMark physics records 13890 versus 4036, a gap exceeding threefold. Floating point math favors the Xeon 66.2 percent (358423 to 215669) and extended instructions 65.5 percent (142682 to 86189).

The remaining PassMark tests narrow but do not close the gap: integer math 458058 to 385290 (18.9 percent), data compression 1816408 to 1412835 (28.6 percent), string sorting 177322 to 125932 (40.8 percent), and single-thread 3195 to 2448 (30.5 percent).

The lone AMD win is PassMark data encryption, 97254 to 89746, a lead of about 8 percent. Given the Xeon's dominance everywhere else, this isolated result likely reflects workload-specific behavior rather than a general strength, but the data records it as recorded: one win for the EPYC 8434P against sixteen for the Xeon 6741P.
