Architecture Differences

The two Xeon processors come from different architectural generations and target different platform strategies. The Intel Xeon E-2378G is built on Rocket Lake-E, part of the Xeon E-2300 series, using Intel's 14 nm process with a die size of 276 mm². The Intel Xeon W-2150B belongs to the Skylake-W family, also on a 14 nm process, but with a much larger die at 484 mm².

Cache layouts differ significantly. The E-2378G uses 80 KB of L1 cache per core and 512 KB of L2 per core, with a shared 16 MB L3 cache. The W-2150B uses 64 KB L1 per core, a larger 1 MB L2 per core, but a smaller shared L3 at 13.75 MB. That means the E-2378G has more total L3 cache (16 MB versus 13.75 MB), while the W-2150B has double the L2 per core.

The socket and platform are entirely different. The E-2378G fits Intel Socket 1200, while the W-2150B uses Intel Socket 2066. This is a fundamental compatibility split: the E-2378G is a mainstream workstation socket, whereas the W-2150B belongs to the high-end desktop (HEDT) platform with more PCIe lanes. The E-2378G provides PCIe Gen 4 with 20 lanes from the CPU, while the W-2150B offers PCIe Gen 3 with 48 lanes. The older W-2150B has more than double the PCIe lane count, which matters for expansion-heavy builds, but the E-2378G's Gen 4 standard provides higher per-lane bandwidth.

Integrated graphics also differentiate the pair. The E-2378G includes Intel UHD Graphics P750, while the W-2150B has no integrated graphics. For systems that need a display output without a discrete GPU, the E-2378G is the only option between the two.

The E-2378G launched in September 2021, while the W-2150B launched in December 2017, nearly four years earlier. The E-2378G remains active in production, whereas the W-2150B is end-of-life.

Where Each One Wins

The Intel Xeon E-2378G wins every benchmark in the head-to-head comparison, but the margins are modest. Its advantages are most pronounced in single-threaded performance, where the higher boost clock of 5.10 GHz versus 4.50 GHz pays off. For workloads that rely on per-core speed, such as lightly threaded rendering tasks, database queries, or interactive workstation use, the E-2378G is the stronger choice.

The Intel Xeon W-2150B's strengths lie outside the Cinebench scores. Its quad-channel memory bus provides 85.3 GB/s of bandwidth, versus 51.2 GB/s on the E-2378G. Applications that are memory-bandwidth sensitive, such as large data manipulation, in-memory analytics, or high-resolution image processing, could benefit more from the W-2150B despite its lower raw CPU scores. Additionally, the W-2150B's 48 PCIe Gen 3 lanes offer far more expansion capability for multiple GPUs, NVMe storage arrays, or specialized accelerators than the E-2378G's 20 Gen 4 lanes.

The W-2150B also has more physical cores (10 versus 8) and threads (20 versus 16), which could help in heavily threaded workloads if the software scales well and memory bandwidth is not the limiting factor. However, the benchmark data shows that in Cinebench's multi-core tests, the E-2378G still comes out ahead, suggesting that the newer architecture's efficiency offsets the core count disadvantage.

The TDP difference is notable: the E-2378G consumes 80 W, while the W-2150B draws 120 W. That means the E-2378G delivers higher benchmark scores while using less power, which is a meaningful efficiency gain. The W-2150B's larger die and older architecture explain the higher power draw.

Head-to-Head Benchmarks

Across all six Cinebench tests recorded in the database, the Intel Xeon E-2378G wins outright. The W-2150B does not win a single benchmark in this comparison.

In Cinebench R15 multicore, the E-2378G scores 1811 against 1750 for the W-2150B, a 3.5% lead. The single-core R15 test shows a similar pattern: 255 versus 246, a 3.7% advantage for the E-2378G. This is the largest percentage delta in any test.

Cinebench R20 multicore gives the E-2378G a score of 7549, compared to 7294 for the W-2150B, again a 3.5% difference. In R20 single-core, the E-2378G posts 1065 against 1029, a 3.5% margin.

Cinebench R23 multicore shows the E-2378G at 17974, with the W-2150B at 17368, a 3.5% lead. The R23 single-core test gives the E-2378G 2537 versus 2452, another 3.5% advantage.

The consistency is striking: the E-2378G beats the W-2150B by roughly 3.5% in every multicore test and by 3.5% to 3.7% in single-core tests. Despite having two fewer cores, the E-2378G's higher boost clock and newer architecture close the core-count gap and actually overturn it. The W-2150B's 10-core advantage does not translate into a multi-core win anywhere in the recorded data.

The average benchmark score in the database places the E-2378G at 5199, sitting at the 60th percentile of all CPUs, while the W-2150B averages 4992 at the 59th percentile. The E-2378G's nearest rivals include the Intel Core i5-13400T (5210, -0.2% delta), the Intel Core i9-10850K (5240, -0.8%), and the Intel Core i7-11700B (5241, -0.8%). The W-2150B sits near the Intel Core i3-12300HE (4995, -0.1%) and the AMD Ryzen 5 PRO 5650G (5002, -0.2%).

The Verdict

The data points clearly to the Intel Xeon E-2378G as the better performer in CPU-bound tasks. It wins every Cinebench test, offers a higher boost clock, includes integrated graphics, uses less power (80 W versus 120 W), and is still in active production. For a workstation that prioritizes single-threaded responsiveness, rendering speed, and modern platform features like PCIe Gen 4, the E-2378G is the obvious pick.

However, the Intel Xeon W-2150B is not without its place. Its quad-channel memory bus delivers 85.3 GB/s of bandwidth, a substantial advantage for memory-heavy workloads. Its 48 PCIe Gen 3 lanes allow for far more expansion cards, storage devices, and accelerators than the E-2378G's 20 Gen 4 lanes. If a system needs maximum memory throughput and extensive PCIe connectivity, and the CPU compute is secondary, the W-2150B remains a viable, though end-of-life, option.

The benchmark results show the E-2378G ahead by 3.5% in multicore and up to 3.7% in single-core, but the W-2150B's platform features are not captured in those scores. Buyers who need raw compute should choose the E-2378G. Buyers who need memory bandwidth and expansion capacity above all else may still consider the W-2150B, but they must accept slower per-core performance and an older, discontinued platform. The E-2378G is the more balanced and future-proof recommendation based on the recorded data.
