The Verdict

The recorded data points to a clear split decision. The Xeon W-2145 is the stronger multi-threaded performer, winning every Cinebench multi-core test and the Geekbench multi-core test by margins ranging from 3.2% to 14%. Its quad-channel memory interface and larger PCIe lane count (48 lanes vs. 16 lanes) make it the better fit for workstation workloads that stress memory throughput and expansion capacity.

The Xeon E-2288G, conversely, takes the single-core crown in Geekbench with a 17.6% advantage (1632 vs. 1345). It also offers a higher boost clock (5.00 GHz vs. 4.50 GHz) and a larger L3 cache (16 MB vs. 11 MB). For users prioritizing lightly threaded responsiveness or needing integrated graphics, the E-2288G is the more practical choice.

The database places both processors at the 58th percentile among all CPUs, meaning they sit at the same overall performance tier. However, the W-2145 holds a higher average benchmark score of 4576 versus 4373 for the E-2288G, a 4.6% difference. The W-2145 also enjoys a wider Cinebench lead across all three versions (R15, R20, R23), consistently hovering around 3.3% in both single and multi-core tests. The E-2288G’s sole win in Geekbench single-core is significant but isolated.

For a pure compute server or workstation with heavy multi-threaded rendering, the W-2145 is the pick. For a compact single-socket system where single-core speed, integrated graphics, and lower power draw matter, the E-2288G fits better. The E-2288G’s 95 W TDP versus the W-2145’s 140 W TDP also favors the former in thermally constrained environments.

Head-to-Head Benchmarks

The Xeon W-2145 dominates the Cinebench suite. In Cinebench R15 multi-core, it scores 1542 against 1493, a 3.3% advantage. The single-core R15 result is identical in margin: 217 versus 210, again 3.3%. Cinebench R20 shows the same pattern, with the W-2145 leading 6425 to 6223 in multi-core and 906 to 878 in single-core, both at 3.2%. Cinebench R23 repeats the trend: 15299 versus 14817 in multi-core and 2159 versus 2091 in single-core, both at 3.3%.

The Geekbench results break the monotony. In Geekbench multi-core, the W-2145 posts 8712 against the E-2288G’s 7639, a commanding 14% lead. This is the largest margin in any test. However, in Geekbench single-core, the E-2288G reverses course with 1632 versus 1345, a 17.6% swing in its favor. That single test is the E-2288G’s only victory across the eight comparisons.

The average benchmark scores reinforce the W-2145’s overall edge: 4576 versus 4373. The nearest rivals in the database show both chips clustering in a tight band. The W-2145 sits 0.6% above the Intel Xeon E-2356G and 0.6% above the Intel Core i7-10700KF, while trailing the Intel Core i9-10900 by 0.8%. The E-2288G is 0.4% ahead of the AMD EPYC 7232P, 1.2% ahead of the Intel Core i7-7820X, and 1.8% ahead of the AMD Ryzen 7 PRO 5750G, but 0.9% behind the AMD Ryzen 7 PRO 4750GE.

Specification Differences

The two processors differ in several core specifications. The W-2145 uses Intel Socket 2066, while the E-2288G uses Intel Socket 1151. The W-2145 has a TDP of 140 W, the E-2288G 95 W. The boost clock differs: 4.50 GHz for the W-2145, 5.00 GHz for the E-2288G. The base clocks match at 3.70 GHz.

Memory configuration diverges sharply. The W-2145 supports quad-channel DDR4 with 85.3 GB/s bandwidth. The E-2288G supports dual-channel DDR4 with 42.7 GB/s. PCIe lane counts also differ: the W-2145 provides 48 PCIe Gen 3 lanes (CPU only), while the E-2288G provides 16 PCIe Gen 3 lanes (CPU only).

Cache sizes differ. The W-2145 has 1 MB L2 per core and 11 MB shared L3. The E-2288G has 256 KB L2 per core and 16 MB shared L3. Both have 64 KB L1 per core. The integrated graphics situation is exclusive to the E-2288G, which includes HD Graphics P630; the W-2145 has none.

Release dates and launch MSRPs differ as well. The W-2145 launched on 2017-08-28 with a launch MSRP of $1113. The E-2288G launched on 2019-05-28 with a launch MSRP of $539. Both are end-of-life and have locked multipliers.

Architecture Differences

The W-2145 is built on Skylake-W architecture with a 14 nm process and a die size of 484 mm². The E-2288G uses Coffee Lake-S WS architecture, also on 14 nm, but with a much smaller die size of 180 mm². Both are manufactured by Intel.

The core and thread counts are identical: 8 cores and 16 threads. However, the underlying design philosophies differ. Skylake-W targets high-end workstation platforms with its larger die, quad-channel memory controller, and massive PCIe lane allocation. Coffee Lake-S WS is a more mainstream-derived server chip, using a smaller die, dual-channel memory, and a more modest PCIe footprint.

The cache hierarchy reflects these design goals. The W-2145 allocates 1 MB of L2 per core, four times the E-2288G’s 256 KB per core. The E-2288G compensates with a larger shared L3 pool of 16 MB versus 11 MB. This suggests the W-2145 favors per-core data locality, while the E-2288G leans on shared cache for cross-core traffic.

The E-2288G’s integrated HD Graphics P630 is a notable architectural addition absent from the W-2145. This makes the E-2288G a self-contained package for systems without discrete graphics. The W-2145, by contrast, assumes a dedicated GPU in a workstation environment.

Memory bandwidth is a direct architectural consequence. The W-2145’s quad-channel interface delivers 85.3 GB/s, exactly double the E-2288G’s 42.7 GB/s from dual-channel. This explains the W-2145’s 14% lead in Geekbench multi-core, where memory throughput often becomes a limiting factor.

The boost clock difference (4.50 GHz vs. 5.00 GHz) stems from the E-2288G’s more efficient power envelope. At 95 W versus 140 W, the E-2288G can push higher frequencies without exceeding its thermal budget. This translates directly into its Geekbench single-core victory. The W-2145’s higher TDP and larger die allow it to sustain heavier multi-threaded loads despite a lower peak clock.

Both processors support DDR4 and ECC memory, and both are end-of-life. The W-2145’s part number is SR3LQ, the E-2288G’s is SRFB3. Neither has an unlocked multiplier. The database records both at the 58th percentile, but the W-2145’s average benchmark score sits 4.6% higher.
