AMD Ryzen 9 5980HS vs Intel Xeon W-2140B Comparison

Head-to-Head Benchmarks

The recorded data splits evenly between these two processors, with two wins apiece across the four shared tests. The most striking result is in Cinebench R23 single-core, where the Intel Xeon W-2140B scores 2074 against the AMD Ryzen 9 5980HS at 1529, a 35.6% advantage. That is a substantial margin, and it flips the usual expectation for a workstation Xeon against a mobile Ryzen part. The older Skylake architecture, despite its age, posts a commanding lead in this particular workload.

The multi-core Cinebench R23 result also favors Intel, though by a smaller margin. The Xeon W-2140B reaches 14692, while the Ryzen 9 5980HS scores 12629, putting Intel 16.3% ahead. That is a meaningful gap in a sustained all-core rendering workload, and it suggests the Xeon's higher base clock and larger L3 cache help it maintain throughput over longer runs.

The AMD processor strikes back decisively in the older Cinebench R15 tests. In multi-core, the Ryzen 9 5980HS scores 2083 against Intel's 1480, a 28.9% advantage. The single-core R15 result follows the same pattern: AMD leads 243 to 209, a 14% edge. These are older benchmark versions, but they still reflect real differences in how the two chips respond to shorter, bursty workloads. The Ryzen's higher boost clock of 4.80 GHz, compared to the Xeon's 4.20 GHz, likely explains part of this advantage in the R15 tests.

Looking at the broader benchmark database, the two chips land close in overall average score. The Intel Xeon W-2140B averages 4272 across all recorded tests, with a percentile rank of 58 among all CPUs. The AMD Ryzen 9 5980HS averages 4121, ranking at percentile 57. The nearest rivals for Intel include the Intel Xeon E5-4669 v3 at 4285 (0.3% higher), the AMD Ryzen 7 PRO 5750G at 4296 (0.6% higher), and the Intel Core i7-1265U at 4248 (0.6% lower). For AMD, the closest competitors are the AMD Ryzen 7 PRO 2700X at 4114 (0.2% lower), the Intel Core i5-12500TE at 4083 (0.9% lower), and the Intel Core i9-9900 at 4163 (1% higher). These rival comparisons show both processors sitting in a dense cluster of mid-range performers, where small percentage differences separate them from the pack.

Architecture Differences

The Intel Xeon W-2140B uses the Skylake-W architecture on a 14 nm process, fabricated by Intel. It packs 8 cores and 16 threads, with a base clock of 3.20 GHz and a boost clock of 4.20 GHz. The die size is 484 mm², which is large for an 8-core part, reflecting the workstation-oriented design with its extensive uncore and memory controllers. The L3 cache is 11 MB shared, with 1 MB L2 per core and 64 KB L1 per core.

The AMD Ryzen 9 5980HS uses the Zen 3 architecture, specifically the Cezanne codename, on a 7 nm process from TSMC. It also has 8 cores and 16 threads, but with a lower base clock of 3.00 GHz and a higher boost clock of 4.80 GHz. The die size is much smaller at 180 mm², and the transistor count is listed at 10,700 million. The L3 cache is larger at 16 MB shared, though the L2 is smaller at 512 KB per core, with the same 64 KB L1 per core.

Memory support differs significantly. The Xeon W-2140B supports DDR4 over a quad-channel bus, delivering 85.3 GB/s of memory bandwidth, and it supports ECC memory. The Ryzen 9 5980HS also supports DDR4 but over a dual-channel bus, yielding 68.3 GB/s, and it does not support ECC. That bandwidth gap of 17 GB/s favors Intel and matters for memory-intensive workstation tasks, though the Ryzen's smaller L2 per core is partially offset by its larger shared L3.

PCIe connectivity also diverges. The Xeon provides Gen 3 with 48 lanes from the CPU, while the Ryzen offers Gen 3 with only 16 lanes. That is a major difference for expandability, as the Xeon can drive multiple GPUs, NVMe drives, or other high-bandwidth peripherals without a chipset bottleneck. The Ryzen's 16 lanes are typical for a mobile part, sufficient for a single GPU and one or two NVMe drives.

The Xeon has no integrated graphics, so it requires a discrete GPU. The Ryzen 9 5980HS includes Radeon Vega 8 integrated graphics, which is a notable feature for a mobile processor. The socket types also differ, with Intel using Socket 2066 and AMD using Socket FP6, and the production statuses reflect their intended lifecycles: the Xeon is end-of-life, while the Ryzen remains active. Release dates are far apart, with the Xeon launching in December 2017 and the Ryzen in January 2021.

Where Each One Wins

The Intel Xeon W-2140B wins in newer Cinebench versions, which tend to stress sustained multi-core performance and modern instruction paths. Its 16.3% lead in R23 multi-core and 35.6% lead in R23 single-core make it the stronger choice for rendering workloads that use current benchmark versions. The larger memory bandwidth of 85.3 GB/s and the quad-channel bus also favor Intel for memory-heavy tasks, and the 48 PCIe lanes allow for extensive expansion, such as multiple GPUs or high-speed storage arrays. ECC memory support adds reliability for long-running workstation or server jobs where data integrity is critical.

The AMD Ryzen 9 5980HS wins in the older Cinebench R15 tests, with a 28.9% lead in multi-core and a 14% lead in single-core. The higher boost clock of 4.80 GHz gives it an edge in bursty, short-duration workloads that do not sustain full power draw for long. Its integrated Radeon Vega 8 graphics make it useful in compact or mobile systems where a discrete GPU is not required. The 35-watt TDP is a dramatic advantage for power-constrained environments, such as laptops or small-form-factor builds, where the 120-watt Xeon would require a much larger cooling solution. The 16 MB L3 cache may also benefit workloads with high data reuse, though the benchmark data does not isolate this effect.

The Verdict

The choice between these two processors depends entirely on the use case and platform constraints. For a workstation or server where power draw is not a primary concern, the Intel Xeon W-2140B offers better performance in current Cinebench R23 tests, plus ECC memory, quad-channel bandwidth, and 48 PCIe lanes. Its 16.3% multi-core and 35.6% single-core advantages in R23 make it the more capable part for modern rendering tasks, and the expandability options are far superior.

For a mobile or low-power system, the AMD Ryzen 9 5980HS is the clear pick. Its 35-watt TDP allows for thin, fanless or low-noise designs that the 120-watt Xeon cannot match. The integrated Radeon Vega 8 graphics eliminate the need for a discrete GPU in many scenarios. The R15 benchmark wins, while based on older software, show that AMD still holds an edge in certain legacy workloads, with a 28.9% multi-core and 14% single-core lead.

The overall average scores are nearly identical, with Intel at 4272 and AMD at 4121, a difference of only 3.7%. The percentile ranks are also close, at 58 and 57 respectively. This means that for general-purpose computing, neither chip has a decisive advantage. The data suggests that buyers should prioritize the platform features, power envelope, and expansion needs rather than raw performance, since the two processors trade blows depending on the benchmark version and workload type. The Xeon is the workstation workhorse, while the Ryzen is the efficient mobile performer.
