Intel Core i7-1375PRE vs Intel Xeon W-2155 Comparison

The Verdict

The benchmark database places the Intel Xeon W-2155 and the Intel Core i7-1375PRE in adjacent performance tiers, with the Xeon holding a narrow but consistent edge across every recorded Cinebench test. The Xeon W-2155 wins all six head-to-head comparisons, with deltas ranging from 1.6% to 1.8%. Its average benchmark score is 5072 against 4985 for the Core i7, a difference of roughly 1.7%. The Xeon also ranks at the 60th percentile among all CPUs in the database, while the Core i7 sits at the 59th percentile. For workloads measured by these Cinebench tests, the Xeon W-2155 is the marginally faster part.

However, the choice between these two processors depends on context beyond raw Cinebench scores. The Xeon W-2155 is a server/workstation part with a 140 W TDP, a 484 mm² die, and support for ECC memory, quad-channel DDR4, and 48 PCIe Gen 3 lanes. The Core i7-1375PRE is a mobile processor with a 28 W TDP, a 217 mm² die, no ECC support, dual-channel memory, and integrated Iris Xe Graphics with 96 execution units. The Core i7 is an active product, while the Xeon is end-of-life. The Xeon has a launch MSRP of $1440; the Core i7 has no recorded launch MSRP.

Given the data, the Xeon W-2155 is the pick for socketed workstation builds where memory bandwidth, PCIe lane count, and ECC reliability matter more than power efficiency. The Core i7-1375PRE is the pick for mobile or embedded designs where the 28 W TDP, integrated graphics, and a smaller physical footprint are decisive. For pure Cinebench throughput, the Xeon wins, but the margin is small enough that the Core i7's efficiency advantages can outweigh the score gap in many real-world deployments.

Architecture Differences

The Xeon W-2155 is built on the Skylake architecture, specifically Skylake-W, using a 14 nm process. Its die measures 484 mm². The Core i7-1375PRE uses the Raptor Lake architecture, specifically Raptor Lake-P, on a 10 nm process with a die size of 217 mm². Both are manufactured by Intel, but the process node difference reflects a significant generational shift: the Raptor Lake part is roughly six years newer in release date, with the Xeon launching in 2017 and the Core i7 in 2023.

The cache hierarchy differs notably. The Xeon W-2155 has 64 KB of L1 cache per core, 1 MB of L2 per core, and 13.75 MB of shared L3 cache. The Core i7-1375PRE has 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. The Core i7 has larger per-core L1 and L2 allocations and nearly double the L3 capacity. The Xeon compensates with fewer cores, which means each of its 10 cores has access to a smaller total pool of L3.

Memory architecture is a major differentiator. The Xeon supports DDR4 memory over a quad-channel bus with a recorded memory bandwidth of 85.3 GB/s. The Core i7 supports both DDR4 and DDR5 over a dual-channel bus, but the database records no memory bandwidth figure for it. The Xeon's quad-channel configuration and higher bandwidth target memory-intensive server and workstation workloads. The Core i7's dual-channel support with DDR5 compatibility suggests a more conventional mobile memory path, though the recorded data does not quantify its bandwidth.

PCIe connectivity also separates the two. The Xeon W-2155 provides 48 PCIe Gen 3 lanes from the CPU. The Core i7-1375PRE provides 20 PCIe Gen 4 lanes from the CPU. The Xeon offers more lanes in terms of count, while the Core i7 offers a newer PCIe generation. For multi-GPU or heavy I/O workstation configurations, the Xeon's lane count is the stronger attribute. For a mobile platform with limited expansion, the Core i7's Gen 4 support with fewer lanes is more typical.

The production status and market segment reinforce the architectural split. The Xeon is an end-of-life server/workstation processor. The Core i7 is an active mobile processor. The Xeon's socket is Intel Socket 2066, a desktop/workstation socket. The Core i7 uses Intel BGA 1744, a soldered mobile package. These are not interchangeable platforms.

Specification Differences

The two processors differ across nearly every specification field in the database. Core count: 10 for the Xeon versus 14 for the Core i7. Thread count is identical at 20 for both. Base clock: the Xeon runs at 3.30 GHz, while the Core i7 lists a base clock of 1900.00 MHz, which in the database format is recorded as 1900.00. Boost clock: the Xeon reaches 4.50 GHz, the Core i7 reaches 4.80 GHz. The Core i7 has a higher boost ceiling, but the Xeon has a much higher base clock.

TDP is the starkest difference: 140 W for the Xeon, 28 W for the Core i7. This is a 5x difference in power draw, which directly impacts cooling requirements, platform design, and sustained performance in constrained environments. The Xeon's 484 mm² die is more than double the Core i7's 217 mm² die, reflecting the older process and more complex workstation I/O.

Memory support: the Xeon uses DDR4 only with a quad-channel bus and 85.3 GB/s bandwidth. The Core i7 supports DDR4 and DDR5 with a dual-channel bus and no recorded bandwidth. ECC memory is present on the Xeon and absent on the Core i7. PCIe: the Xeon has Gen 3 with 48 lanes, the Core i7 has Gen 4 with 20 lanes. Integrated graphics: none on the Xeon, Iris Xe Graphics 96EU on the Core i7.

Release dates are far apart: the Xeon launched in 2017, the Core i7 in 2023. The Xeon is end-of-life, the Core i7 is active. The Xeon has a launch MSRP of $1440; the Core i7 has no recorded launch MSRP. Neither processor has an unlocked multiplier. The part numbers are SR3LR for the Xeon and SRMRK for the Core i7.

Head-to-Head Benchmarks

The head-to-head results show a consistent, if modest, lead for the Xeon W-2155 across all six Cinebench tests. In Cinebench R15 multicore, the Xeon scores 1767 against 1737 for the Core i7, a 1.7% advantage. In R15 single-core, the Xeon scores 249 against 245, a 1.6% edge. The R20 multicore test shows the Xeon at 7365 versus 7239, again a 1.7% lead. R20 single-core gives the Xeon 1039 against 1021, a 1.8% margin. The R23 multicore test has the Xeon at 17538 versus 17236, a 1.8% gap. Finally, R23 single-core shows the Xeon at 2475 versus 2433, a 1.7% difference.

The pattern is clear: the Xeon wins every test, and the margins are tightly clustered between 1.6% and 1.8%. The largest single percentage delta is 1.8%, appearing in R20 single-core and R23 multicore. The smallest is 1.6% in R15 single-core. This consistency suggests that the Xeon's advantage is not workload-specific within the Cinebench suite; it holds across both single-threaded and multi-threaded render tests.

For context, the Xeon's nearest rivals in the database include the AMD Ryzen 7 PRO 5750GE with an average score of 5070 (0% delta), the Intel Core i9-12900TE at 5050 (0.4% delta), and the Intel Core i7-11850HE at 5095 (-0.4% delta). The Core i7-1375PRE's nearest rivals include the Intel Core i5-12600HE at 4980 (0.1% delta), the Intel Xeon W-2150B at 4992 (-0.1% delta), and the Intel Core i3-12300HE at 4995 (-0.2% delta). These rival comparisons show that both processors sit in a dense performance cluster, where a few percentage points separate many parts.

The Core i7-1375PRE is not without strengths in the recorded data. It has 14 cores versus 10, a 4.80 GHz boost clock versus 4.50 GHz, 24 MB of L3 versus 13.75 MB, and a 28 W TDP versus 140 W. Yet in the Cinebench tests, the Xeon's higher base clock, quad-channel memory, and older but robust Skylake architecture edge out the newer mobile part. The Core i7's higher core count does not translate into a multicore win, and its higher boost clock does not deliver a single-core win. The recorded benchmarks indicate that the Xeon's overall design, despite being older and power-hungry, produces slightly better render performance in this specific comparison.
