Intel Pentium Silver N6005 vs Intel Xeon W-2102 Comparison

The Intel Xeon W-2102 and Intel Pentium Silver N6005 are both four-core, four-thread processors, but they target completely different segments of the market. The Xeon W-2102 is a workstation-class part from 2017, built for the Intel Socket 2066 platform with a 120 W TDP, while the Pentium Silver N6005 is a low-power mobile chip from the Jasper Lake family with a 10 W TDP. Despite their different origins, benchmark results show them landing in a very narrow performance band, with the Pentium Silver holding a slight edge across every recorded test.

Where Each One Wins

The head-to-head benchmark data is unambiguous: the Intel Pentium Silver N6005 wins all six recorded comparisons. The Xeon W-2102 does not claim a single victory in any of the Cinebench R15, R20, or R23 tests, whether single-core or multi-core. The margins are consistent, ranging from 1.5% to 1.7% in favor of the Pentium Silver. This means the N6005 is the faster part in pure compute workloads, despite its dramatically lower power envelope.

The Xeon W-2102, however, wins in areas that are not captured by Cinebench. It supports quad-channel DDR4 memory with a bandwidth of 85.3 GB/s, compared to the Pentium Silver's dual-channel setup at 46.9 GB/s. The Xeon also supports ECC memory, which the Pentium Silver does not. For workloads that depend on memory throughput rather than raw core speed, such as certain server or workstation tasks, the Xeon's platform advantages could make it the more suitable choice. The Pentium Silver counters with integrated UHD Graphics 32EU, making it the only one of the two that can output video without a discrete GPU.

Architecture Differences

The two processors come from entirely different architectural lineages. The Xeon W-2102 is based on Skylake-W, built on Intel's 14 nm process, with a die size of 484 mm². It is part of the Xeon W generation, a server and workstation family. The Pentium Silver N6005 uses the Tremont architecture, codenamed Jasper Lake, fabricated on a 10 nm process with a much smaller die size of 63.8 mm². This difference in process node and die size explains the massive gap in TDP: 120 W for the Xeon versus 10 W for the Pentium Silver.

Cache configurations also differ significantly. The Xeon W-2102 has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 8.25 MB of shared L3 cache. The Pentium Silver N6005 also has 64 KB of L1 per core, but its L2 cache is 1.5 MB shared, and its L3 cache is 4 MB shared. The Xeon therefore has more total cache, but the Pentium Silver's shared L2 design is a different approach to cache hierarchy.

Memory support separates the two further. The Xeon uses DDR4 exclusively with a quad-channel memory bus, while the Pentium Silver supports both DDR4 and LPDDR4 with a dual-channel bus. PCIe connectivity also differs: the Xeon provides 48 Gen 3 lanes from the CPU, whereas the Pentium Silver offers only 8 Gen 3 lanes. The Xeon supports ECC memory, a critical feature for reliability in workstation environments, while the Pentium Silver does not.

Specification Differences

The two processors differ in nearly every major specification category. The Xeon W-2102 has a base clock of 2.90 GHz with no boost clock listed, while the Pentium Silver N6005 has a base clock of 2000.00 MHz (2.00 GHz) and a boost clock of 3.30 GHz. The Xeon uses the Skylake architecture on a 14 nm process with a 484 mm² die, while the Pentium Silver uses Tremont on a 10 nm process with a 63.8 mm² die.

Cache layouts are distinct: the Xeon has 1 MB of L2 per core and 8.25 MB of shared L3, while the Pentium Silver has 1.5 MB of shared L2 and 4 MB of shared L3. Memory support differs, with the Xeon supporting only DDR4 in quad-channel mode, and the Pentium Silver supporting DDR4 and LPDDR4 in dual-channel mode. The Xeon offers 48 PCIe Gen 3 lanes, whereas the Pentium Silver offers 8. The Xeon has ECC support, the Pentium Silver does not. The Xeon is a server and workstation part with a 120 W TDP, while the Pentium Silver is a mobile part with a 10 W TDP.

Head-to-Head Benchmarks

The recorded data shows a consistent pattern across all six benchmark tests. In Cinebench R15 multi-core, the Pentium Silver N6005 scores 447 against the Xeon W-2102's 440, a 1.6% advantage. In the single-core variant, the Pentium Silver scores 63 versus 62, again 1.6% ahead. Moving to Cinebench R20, the Pentium Silver leads 1866 to 1835 in multi-core, a 1.7% margin, and 263 to 259 in single-core, a 1.5% margin.

The most recent tests, Cinebench R23, show the same story. The Pentium Silver scores 4444 in multi-core versus the Xeon's 4370, a 1.7% lead, and 627 in single-core versus 617, a 1.6% lead. The largest recorded delta is 1.7% in the two R20 multi-core and R23 multi-core tests, while the smallest is 1.5% in R20 single-core. The Pentium Silver also has a Geekbench result in the database, scoring 1469 multi-core and 564 single-core, though no comparable Geekbench score is recorded for the Xeon W-2102.

Looking at the broader database context, both processors sit at a similar percentile. The Xeon W-2102 is at the 35th percentile among all CPUs, with an average benchmark score of 1264. Its nearest rivals include the Intel Core i3-1005G1 with a score of 1265 (0.1% ahead) and the AMD Athlon 200GE with a score of 1261 (0.3% behind). The Pentium Silver N6005 sits at the 34th percentile with an average score of 1218. Its nearest rivals include the Intel Core i7-3632QM at 1219 (0.1% ahead) and the Intel Core i5-2500 at 1220 (0.2% ahead). This places both CPUs in the same performance tier, with the Pentium Silver scoring slightly higher in the direct comparisons.

The Verdict

The data points to a clear conclusion for raw compute performance: the Intel Pentium Silver N6005 is the faster processor in every Cinebench test recorded. It wins all six head-to-head matchups, with margins that are small but consistent. For users whose priority is single-threaded or multi-threaded CPU performance in applications like Cinebench, the Pentium Silver is the better choice.

The Xeon W-2102, however, should not be dismissed entirely. Its platform features are significantly different. The quad-channel memory bus with 85.3 GB/s bandwidth is more than double the Pentium Silver's 46.9 GB/s, and the Xeon supports ECC memory, which is essential for error-correcting workloads in server or workstation environments. The Xeon also provides 48 PCIe Gen 3 lanes versus 8, making it far more expandable for add-in cards, storage controllers, or GPUs. Its 120 W TDP and Socket 2066 platform indicate a system designed for sustained, high-throughput operation.

The Pentium Silver N6005 wins on efficiency and integration. Its 10 W TDP is a fraction of the Xeon's 120 W, and it includes integrated UHD Graphics 32EU, meaning a complete system can run without a discrete graphics card. Its mobile form factor, BGA 1338, is soldered to the board, which suits compact and low-power designs. The choice between the two depends entirely on the use case: the Pentium Silver for lightweight, power-conscious computing with a slight performance edge, and the Xeon for workstation-class systems that need ECC, high memory bandwidth, and extensive PCIe connectivity.
