Intel Xeon W-2150B

The Intel Xeon W-2150B is a server/workstation processor from Intel’s Skylake-W generation, built on a 14 nm process with a 484 mm² die. It has 10 cores and 20 threads, a 3.00 GHz base clock, and a 4.50 GHz boost clock, with a 120W TDP. It uses Intel Socket 2066, supports quad-channel DDR4 memory with ECC, and provides 48 PCIe Gen 3 lanes from the CPU. The cache layout includes 64 KB L1 per core, 1 MB L2 per core, and 13.75 MB shared L3. There is no integrated graphics. The part number is SR3LS, the release date is 2017-12-20, and production is end-of-life. In the benchmark database it sits in the 63rd percentile of all CPUs, with an average benchmark score of 5014.

Benchmark Performance

The Cinebench results show a processor that scales well with thread count. The W-2150B scores 1760 in Cinebench R15 multicore, 7337 in R20 multicore, and 17470 in R23 multicore. Its single-core scores in the same suite are 248, 1035, and 2466 respectively. Geekbench reports a multicore score of 8481 and a single-core score of 1314. The average benchmark score across the dataset is 5014, which places the chip in the 63rd percentile of all CPUs.

That percentile is not a top-tier placement, but the nearest rivals show how tightly grouped this segment is. The W-2150B trails the Intel Core i9-9820X by 0.2%, with the i9 posting a 5022 average score. It trails the Intel Xeon Gold 6334 by 0.6%, as that chip averages 5043. It leads the AMD Ryzen 9 5980HS by 0.4%, with that chip averaging 4993, and it leads the Intel Xeon Gold 5315Y by 0.9%, with that chip averaging 4969. These deltas are all close, so the average score position is best described as a tight cluster rather than a clear performance hierarchy.

The multi-core scores are the main driver of that average. Cinebench R23 multicore at 17470 is substantially higher than the R23 single-core score of 2466, and the same pattern appears in R20, R15, and Geekbench. This is not a processor that leads with single-thread speed; it leads with throughput under heavy parallel load.

Platform and Compatibility

The platform story is straightforward. The W-2150B is an Intel Socket 2066 part, so the motherboard must use that socket. Memory support is DDR4 with a quad-channel controller and 85.3 GB/s of memory bandwidth. ECC memory is supported, which makes the platform suitable for workstations where memory integrity matters. The CPU provides 48 PCIe Gen 3 lanes, which allows for multiple accelerators, storage devices, or other expansion cards without relying on a separate chipset for all connectivity.

The chip is built on Skylake-W architecture and uses the 14 nm process node with a 484 mm² die. The cache hierarchy is 64 KB L1 per core, 1 MB L2 per core, and 13.75 MB shared L3. This gives each core a fast private working set while providing a shared pool for data used across all cores. There is no integrated graphics, so a discrete GPU is required for any display output.

Production status is end-of-life, and the release date is 2017-12-20. Because it is a Socket 2066 Skylake-W processor, the upgrade path is tied to that platform. The data does not include a list of compatible motherboard chipsets, so system builders should rely on the motherboard vendor’s support for this specific CPU and socket.

Single-Thread vs Multi-Thread Behavior

The single-thread and multi-thread results paint clearly different pictures. Geekbench single-core is 1314, while Geekbench multicore is 8481. Cinebench R15 single-core is 248 versus 1760 multicore. Cinebench R20 single-core is 1035 versus 7337 multicore. Cinebench R23 single-core is 2466 versus 17470 multicore. In every benchmark, the multi-core score is far higher than the single-core score.

For lightly threaded tasks, the meaningful specification is the 3.00 GHz base clock and the 4.50 GHz boost clock. The boost clock is the ceiling for single-thread response, and the scores confirm that the chip is competitive but not dominant in that area. For heavily threaded workloads, the 10 cores and 20 threads determine the throughput. Render engines, compilation workloads, and similar parallel applications will use those threads and directly benefit from the high multi-core scores. The Cinebench R23 multicore result of 17470 indicates that sustained all-core operation is where this processor earns its place in a workstation.

How It Compares

Against the Intel Core i9-9820X, the W-2150B is effectively a dead heat. The i9-9820X has an average benchmark score of 5022, which is 0.2% higher than the W-2150B’s 5014. That difference is small enough that most real workloads would not show a meaningful gap.

Against the AMD Ryzen 9 5980HS, the W-2150B has a slight edge. The Ryzen 9 5980HS averages 4993, and the W-2150B is 0.4% ahead. This is another near-even comparison, so the practical decision would come down to platform features and system requirements rather than raw benchmark score.

Against the Intel Xeon Gold 6334, the W-2150B is 0.6% behind. The Xeon Gold 6334 averages 5043, which makes it the highest-scoring chip among the nearest rivals listed in the data. The W-2150B is close, but the Gold 6334 has the higher average score.

Against the Intel Xeon Gold 5315Y, the W-2150B leads by 0.9%. The Gold 5315Y averages 4969, the lowest average score among the nearest rivals. This is the largest delta in the group, yet it is still a narrow margin. The W-2150B has an average score of 5014, so it sits in the same performance band as all four rivals.

Power and Thermals

The W-2150B is rated at a 120W TDP. For a 10-core, 20-thread Skylake-W processor, that is a moderate power class. The absence of integrated graphics means the thermal solution is dedicated entirely to the CPU cores. The multiplier is locked, as indicated by multiplierUnlocked being false, so tuning is limited and the processor is expected to operate within its stock specifications. Cooling should be chosen around the 120W rating and the sustained load pattern of heavily threaded workloads such as the Cinebench R23 multicore test, where the chip scores 17470. With the base clock at 3.00 GHz and the boost clock at 4.50 GHz, the thermal envelope is defined by all-core and lightly threaded boost behavior. A capable cooler suited to this class of processor should be able to handle the workload, but the data does not include measured thermal results beyond the TDP rating.
