AMD Ryzen 9 8940HX vs Intel Xeon w7-2575X Comparison

Where Each One Wins

The Intel Xeon w7-2575X dominates the AMD Ryzen 9 8940HX in the majority of recorded benchmarks, winning 10 of the 15 head-to-head tests. The Xeon takes every Cinebench single-core and multi-core test except for Cinebench R15 multi-core, where the Ryzen counterattacks. For sustained all-core rendering, the Xeon leads Cinebench R23 multi-core by 36.1% with a score of 44277 versus 32521, and its Cinebench R20 multi-core result of 18596 further confirms the workstation-class throughput advantage.

The AMD Ryzen 9 8940HX wins 5 tests, but the margin of victory is narrow in most cases. Its largest wins come in single-thread PassMark tests, scoring 3874 versus the Xeon's 3300, a 14.8% lead. The Ryzen also wins Cinebench R15 multi-core by 16.7% (5355 versus 4463), which is notable because it is the only multi-core test where AMD takes the lead. The other AMD wins are marginal: data encryption at 39318 versus 39295 (0.1% ahead), find prime numbers at 251 versus 218 (13.1% ahead), and the two identical PassMark single-thread tests.

The Xeon's wins are often decisive. Floating point math shows the largest gap, with the Xeon scoring 171427 versus 113921, a 50.5% advantage. Extended instructions favor Intel by 30.7%, and data compression by 21.3%. Integer math, multithread, physics, and random string sorting all go to Intel with margins ranging from 3.5% to 16.2%. The single-core Cinebench results are extreme: the Xeon leads R23 single-core by 226% and R15 single-core by 115.8%.

Looking at the average benchmark scores, the Xeon posts 88172 against the Ryzen's 81103, a difference of roughly 8.7%. Both chips sit near the top of the database, with the Xeon at the 96th percentile and the Ryzen at the 95th percentile. The recorded data therefore shows two very capable processors, but the Xeon is consistently ahead in compute-heavy workloads, while the Ryzen shows strength in specific single-threaded and light multi-core scenarios.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Xeon w7-2575X is built on Sapphire Rapids using Intel's 10 nm process and packs 22 cores with 44 threads. It belongs to the Xeon W family, a server and workstation segment, and ships on Intel Socket 4677. The AMD Ryzen 9 8940HX is a mobile part from the 8000 series, built on Zen 4 (Dragon Range) using TSMC's 5 nm process, with 16 cores and 32 threads on AMD Socket FL1.

Cache layouts differ substantially. The Xeon allocates 80 KB of L1 per core, 2 MB of L2 per core, and a shared 45 MB L3 cache. The Ryzen uses 64 KB of L1 per core, 1 MB of L2 per core, and a larger 64 MB L3 pool. Despite having fewer cores, the Ryzen's L3 is 19 MB larger, which can help in workloads that fit within the shared cache.

Memory architecture separates the two clearly. The Xeon runs DDR5 in quad-channel mode with a memory bandwidth of 153.6 GB/s, while the Ryzen runs DDR5 in dual-channel mode with 83.2 GB/s. The Xeon doubles the memory channels and nearly doubles the bandwidth, which matters for large data sets and multi-threaded rendering. The Xeon also supports ECC memory, while the Ryzen does not.

PCIe capabilities also differ. The Xeon provides Gen 5 with 64 lanes from the CPU, while the Ryzen provides Gen 5 with 28 lanes. The Xeon has no integrated graphics, whereas the Ryzen includes a Radeon 610M iGPU for display output. Power envelopes are far apart: the Xeon has a TDP of 250 W, the Ryzen 55 W. The Ryzen's boost clock reaches 5.30 GHz versus the Xeon's 4.80 GHz, while the Xeon has a higher base clock at 3.00 GHz versus 2.40 GHz.

The Xeon launched on 2024-08-23 with a launch MSRP of $1689. The Ryzen released later, on 2025-04-22, and has no recorded launch MSRP in the database. Both are active in production, and both have unlocked multipliers.

The Verdict

From the recorded data, the Intel Xeon w7-2575X is the stronger processor for multi-threaded workstation workloads. It wins Cinebench R23 multi-core by 36.1%, floating point math by 50.5%, extended instructions by 30.7%, data compression by 21.3%, and integer math by 16.2%. Its 22 cores, 44 threads, quad-channel memory, and 153.6 GB/s bandwidth deliver a decisive edge in rendering, number crunching, and data-heavy tasks. The Xeon also wins every Cinebench single-core test by massive margins, including a 226% lead in R23 single-core, which is surprising given the Ryzen's higher boost clock.

The AMD Ryzen 9 8940HX is the efficient mobile alternative. It wins PassMark single-thread by 14.8% and Cinebench R15 multi-core by 16.7%, but its overall average score is lower. The Ryzen's 55 W TDP makes it suitable for laptops, while the Xeon's 250 W TDP requires a workstation platform. For users who need a mobile processor with strong single-thread performance and moderate multi-core capability, the Ryzen fits. For users who need maximum throughput in a desktop or server workstation, the Xeon is the clear choice based on the benchmark results.

The nearest rivals data supports the Xeon's position. The Xeon sits close to the AMD Ryzen AI Max+ 392, which averages 90541 against the Xeon's 88172 (a 2.6% gap), and the Intel Xeon 654 at 90717 (a 2.8% gap). The Ryzen 9 8940HX, meanwhile, matches the Intel Xeon w5-3535X and Intel Core i9-14900KS almost exactly, with delta percentages at 0. The Ryzen's nearest rival cluster is slightly below the Xeon's cluster, which aligns with the average score difference.

Head-to-Head Benchmarks

The largest Intel win is in Cinebench R23 single-core, where the Xeon scores 6250 against the Ryzen's 1917, a 226% advantage. This is an enormous gap and indicates that the Xeon's single-core implementation, despite a lower boost clock of 4.80 GHz versus 5.30 GHz, is far more efficient in this workload. Cinebench R15 single-core follows the same pattern, with the Xeon at 630 versus 292, a 115.8% lead.

Floating point math shows the Xeon's raw compute strength: 171427 versus 113921, a 50.5% margin. Extended instructions follow at 30.7% (62498 versus 47802). Data compression goes to Intel by 21.3% (789817 versus 650984), and integer math by 16.2% (219924 versus 189221). Cinebench R23 multi-core gives Intel a 36.1% win (44277 versus 32521), and Cinebench R20 multi-core shows a similar trend with 18596 versus the Ryzen's absent entry in the head-to-head list.

The AMD wins are smaller in absolute terms. PassMark single-thread goes to the Ryzen at 3874 versus 3300, a 14.8% lead. Cinebench R15 multi-core goes to AMD at 5355 versus 4463, a 16.7% lead. Find prime numbers favors AMD 251 versus 218, a 13.1% margin. Data encryption is nearly tied, with AMD at 39318 versus Intel's 39295, a 0.1% difference. The Ryzen's multithread score of 49731 trails the Xeon's 52091 by 4.7%, and its physics score of 2104 trails 2222 by 5.6%. Random string sorting goes to Intel 77986 versus 75381, a 3.5% margin.

The overall win count is 10 for Intel and 5 for AMD. The Xeon's victories tend to be larger, with several exceeding 20%, while the Ryzen's wins are mostly under 17%. The only AMD win above 15% is Cinebench R15 multi-core. This pattern suggests that the Xeon is better suited for sustained, multi-threaded compute, while the Ryzen's single-thread PassMark result and R15 multi-core result indicate a different optimization profile, likely tied to its higher boost clock and mobile design.
