AMD Athlon Silver 10 vs Intel Xeon W-2191B Comparison

Head-to-Head Benchmarks

The benchmark comparison between the Intel Xeon W-2191B and the AMD Athlon Silver 10 is unusual because the two processors do not share any common benchmark tests in the database. The Xeon W-2191B was measured with Cinebench R15, R20, R23, and Geekbench workloads, while the Athlon Silver 10 was evaluated using PassMark tests. This means a direct score-for-score comparison is impossible, but the aggregate data and percentile rankings still reveal a clear hierarchy.

The Intel Xeon W-2191B's average benchmark score is 6531, which places it at the 62nd percentile of all CPUs tracked. The AMD Athlon Silver 10, by contrast, records an average benchmark score of 6849, sitting at the 63rd percentile. In absolute terms, the Athlon has a higher average score by 318 points, roughly 4.9% above the Xeon. That is a small edge, but the nature of the workloads matters. The Xeon's raw multi-core muscle is substantial: it scored 2407 in Cinebench R15 multi-core, 10032 in R20 multi-core, and 23887 in R23 multi-core. Its single-core results are 339, 1416, and 3372 in the same tests. The Geekbench scores are 9614 multi-core and 1182 single-core. These numbers reflect a processor built for sustained, heavy parallel work.

The Athlon Silver 10's PassMark results tell a different story. Its multithread score is 3543, its single-thread score is 2089, and it achieves 9354 in integer math, 5936 in floating point math, and 4736 in random string sorting. The data compression score is 42492, and data encryption is 2125. Extended instructions score 2747, physics 210, and find prime numbers 13. These are not comparable to Cinebench or Geekbench, but they show a chip that is competent in light, single-threaded tasks and surprisingly strong in data compression.

The nearest rival data reinforces the positioning. The Xeon W-2191B sits within 0.8% of the Intel Core i9-7960X, Intel Xeon D-2796TE, Intel Atom x7405C, and Intel Core i5-13500E. The Athlon Silver 10 is within 0.7% of the AMD Athlon X4 970, Intel Core i3-1115G4, Intel Xeon W-2195, and Intel Xeon Gold 6154. Notably, the Athlon's nearest rivals include server-class Xeons with far higher core counts, which suggests its average score is lifted by specific workloads rather than general multi-core dominance.

Where Each One Wins

The Intel Xeon W-2191B wins decisively in multi-threaded, compute-heavy scenarios. Its 18 cores and 36 threads give it a massive advantage in rendering, scientific computing, and any workload that scales across cores. The Cinebench R23 multi-core score of 23887 is nearly seven times its single-core score of 3372, which is a typical pattern for a high-core-count workstation part. The Geekbench multi-core score of 9614 versus the single-core 1182 reinforces this. For video encoding, 3D rendering, virtual machines, or compiling, the Xeon is the clear choice based on the recorded data.

The AMD Athlon Silver 10 wins in efficiency-driven mobile scenarios. Its 15 watt TDP and integrated Radeon 610M graphics make it suitable for compact laptops and low-power systems. The PassMark data shows it performs well in data compression (42492) and integer math (9354), which are common in file archiving and office productivity. Its single-thread score of 2089 is respectable for a 2-core, 2-thread chip. The physics score of 210 is low, indicating it is not suited for simulation or heavy gaming physics.

The data implies a split: the Xeon is a workstation and server tool, while the Athlon is a thin-and-light mobile processor. The Xeon's memory bandwidth of 85.3 GB/s and quad-channel DDR4 support enable it to feed its many cores, while the Athlon's 88.0 GB/s bandwidth with dual-channel LPDDR5 is more modest but adequate for its lower core count. The Athlon also has a higher boost clock relative to its base (2.40 GHz to 3.50 GHz) than the Xeon (2.30 GHz to 4.30 GHz), which helps it in bursty single-threaded tasks.

Architecture Differences

The architectural gap between these two processors is wide. The Intel Xeon W-2191B is built on the Skylake-W architecture, using a 14 nm process from Intel's own foundry. It has 18 cores and 36 threads, with a base clock of 2.30 GHz and a boost clock of 4.30 GHz. The die size is 484 mm². Its cache hierarchy is substantial: 64 KB of L1 per core, 1 MB of L2 per core, and 24.75 MB of shared L3 cache. The memory controller supports quad-channel DDR4 with a bandwidth of 85.3 GB/s. It uses Intel Socket 2066 and provides 48 PCIe Gen 3 lanes from the CPU. It supports ECC memory, which is critical for workstation reliability. The Xeon was released in December 2017 and is now end-of-life.

The AMD Athlon Silver 10 uses the Zen 2 architecture, specifically the Mendocino codename, built on a 6 nm process at TSMC. It has only 2 cores and 2 threads, with a base clock of 2.40 GHz and a boost clock of 3.50 GHz. The die size is 100 mm², which is much smaller than the Xeon's. Its cache is smaller: 64 KB of L1 per core, 512 KB of L2 per core, and 2 MB of shared L3. Memory support is dual-channel LPDDR5 with a bandwidth of 88.0 GB/s. It uses AMD Socket FT6 and provides only 4 PCIe Gen 3 lanes from the CPU. It does not support ECC memory. The Athlon includes integrated Radeon 610M graphics, which the Xeon lacks entirely. The Athlon was released in September 2025 and remains in active production.

The process node difference is significant: 14 nm versus 6 nm. The Xeon's larger die and older node explain its higher power draw and heat output, while the Athlon's smaller and denser node allows a 15 watt TDP. The Xeon's 140 watt TDP is nearly ten times higher. The transistor counts are not recorded in the database, so a direct transistor comparison is not possible. The cache sizes reflect the core counts: the Xeon needs large shared L3 for its 18 cores, while the Athlon's 2 MB L3 is sufficient for 2 cores.

The Verdict

The data points to two completely different use cases. The Intel Xeon W-2191B is for anyone who needs massive multi-core throughput. Its Cinebench R23 multi-core score of 23887 and 36 threads make it suitable for rendering, simulation, and server workloads. It supports ECC memory, has 48 PCIe Gen 3 lanes, and offers 85.3 GB/s of memory bandwidth. The 140 watt TDP and lack of integrated graphics are acceptable trade-offs in a workstation. It is end-of-life, but the benchmark data shows it remains competitive with newer processors in its class.

The AMD Athlon Silver 10 is for lightweight, power-conscious mobile systems. Its 15 watt TDP, integrated Radeon 610M graphics, and 6 nm process make it efficient. The PassMark data shows strong single-thread performance (2089) and excellent data compression (42492). It is active production, released in 2025, and sits at the 63rd percentile overall, slightly above the Xeon. However, its 2 cores and 2 threads limit it to basic productivity, web browsing, and light tasks.

The choice is clear: if the workload is multi-threaded and demands reliability, the Xeon W-2191B is the stronger option. If the priority is portability, low power consumption, and integrated graphics, the Athlon Silver 10 is the better fit. The benchmark records show no overlap in their test suites, so users should select based on the specific workload rather than comparing aggregate scores directly. The Xeon's 62nd percentile and the Athlon's 63rd percentile are close, but their architectures and intended use cases could not be more different.
