Intel Core i5-1340P vs Intel Xeon W-2145 Comparison

The Intel Xeon W-2145 and Intel Core i5-1340P are separated by over five years of platform evolution, yet their benchmark averages land nearly on top of each other. The Xeon W-2145 posts an average benchmark score of 4576, while the i5-1340P achieves 4545, a difference of just 0.7%. Both processors sit at the 58th percentile among all CPUs, making them statistical equals in overall compute output. The head-to-head data, however, tells a more nuanced story, as the mobile i5 wins every single benchmark in the comparison suite.

Head-to-Head Benchmarks

The i5-1340P claims a clean sweep across all six benchmark tests, but the margin is remarkably consistent and narrow. In every Cinebench test—R15, R20, and R23—the i5-1340P leads by exactly 2.7%. For instance, in Cinebench R23 multi-core, the i5-1340P scores 15716 against the Xeon W-2145's 15299. The single-core results follow the same pattern: 2218 versus 2159 in Cinebench R23 single-core, again a 2.7% advantage for the i5.

This uniformity suggests the i5-1340P's advantage is architectural rather than workload-specific. The i5-1340P also edges ahead in Cinebench R15 multi-core (1584 vs 1542) and R20 multi-core (6600 vs 6425). The consistency is striking—exactly 2.7% across every test, regardless of whether the workload scales across cores or runs on a single thread. This is not a case of one chip winning by a wide margin in specific scenarios; rather, the i5-1340P simply does everything slightly better in these CPU-bound tests.

Interestingly, the Xeon W-2145 does not win a single benchmark in the head-to-head suite. Its rival list shows it matching the i5-1340P's average score within 0.7%, yet the actual benchmark results reveal a systematic, if modest, deficit. The Xeon's best showing comes in Geekbench multi-core, where it scores 8712, but the i5-1340P has no Geekbench result in the head-to-head data, so that comparison remains incomplete.

Architecture Differences

The two processors represent fundamentally different design philosophies. The Xeon W-2145 uses the Skylake-W architecture on a 14 nm process, with a die size of 484 mm². It packs 8 cores and 16 threads, with a base clock of 3.70 GHz and a boost clock of 4.50 GHz. The i5-1340P, by contrast, uses Raptor Lake-P on a 10 nm node, and while its die size is not listed, it contains 12 cores and 16 threads. The i5's base clock is listed at 1900.00 MHz (1.90 GHz), but its boost clock reaches 4.60 GHz, slightly higher than the Xeon's.

Cache configurations differ notably. The Xeon W-2145 has 64 KB of L1 cache per core and 1 MB of L2 per core, with 11 MB of shared L3. The i5-1340P offers 80 KB of L1 per core, 2 MB of L2 per core, and 12 MB of shared L3. The i5 thus has more cache per core at every level, which helps explain its consistent 2.7% lead despite lower power envelopes.

Memory support is another differentiator. The Xeon W-2145 supports DDR4 memory over a quad-channel bus, delivering 85.3 GB/s of bandwidth, and includes ECC memory support. The i5-1340P supports both DDR4 and DDR5 over a dual-channel bus, but its memory bandwidth is not listed, and it lacks ECC support. The Xeon also offers 48 PCIe Gen 3 lanes, while the i5 provides 20 PCIe Gen 4 lanes—the newer standard but fewer lanes.

Perhaps the most telling difference is the integrated graphics. The Xeon W-2145 has none, while the i5-1340P includes Iris Xe Graphics 80EU. This alone shifts the i5's use case dramatically toward mainstream mobile systems where a discrete GPU is optional.

Where Each One Wins

Based strictly on the benchmark data, the i5-1340P wins every CPU benchmark in the comparison. That makes it the clear choice for any workload measured by Cinebench R15, R20, or R23, whether single-threaded or multi-threaded. The i5's 12 cores and 16 threads give it a physical core advantage over the Xeon's 8 cores and 16 threads, even though thread counts match.

However, the Xeon W-2145 holds advantages that benchmarks do not capture. Its quad-channel memory bus with 85.3 GB/s bandwidth is built for memory-intensive server and workstation tasks. Its ECC memory support is critical for data integrity in professional environments. The 48 PCIe Gen 3 lanes allow for extensive expansion—multiple GPUs, storage controllers, or networking cards—something the i5's 20 Gen 4 lanes cannot match.

The i5-1340P, being a mobile processor with a 28 W TDP compared to the Xeon's 140 W TDP, is designed for laptops and compact systems. Its integrated Iris Xe Graphics means it can function without a discrete GPU, which the Xeon cannot. The i5 also supports DDR5 memory, a newer standard than the Xeon's DDR4-only support.

In practice, the i5-1340P wins on raw CPU throughput in the tested benchmarks, but the Xeon wins on platform capabilities: memory bandwidth, ECC, PCIe lane count, and workstation-grade expandability.

The Verdict

The data paints a clear picture for raw CPU performance: the Intel Core i5-1340P is the faster processor in every benchmark tested. Its 2.7% lead across all Cinebench versions, both single-core and multi-core, is consistent and unambiguous. Anyone choosing solely on CPU throughput should select the i5-1340P.

The Intel Xeon W-2145, however, justifies its existence through platform features that benchmarks do not measure. Its quad-channel memory with 85.3 GB/s bandwidth, ECC support, and 48 PCIe Gen 3 lanes make it a workstation processor for memory-heavy and expansion-heavy workloads. The i5-1340P's dual-channel memory and 20 PCIe Gen 4 lanes, while newer, offer fewer lanes and no ECC.

For a mobile or compact system where integrated graphics and low power consumption matter, the i5-1340P is the obvious choice. For a server or workstation requiring ECC, massive memory bandwidth, and extensive PCIe expansion, the Xeon W-2145 remains relevant despite its end-of-life status. The benchmarks show the i5 is faster in CPU-bound tests, but the Xeon wins where the platform matters more than the processor.
