CPU Comparison

The Intel Xeon W-2104 and Intel Core i5-760 are both 4-core, 4-thread processors, but they represent vastly different eras and market segments of Intel's lineup. The Xeon W-2104 is a Skylake-W workstation part built on a 14 nm process, while the Core i5-760 is a Lynnfield desktop chip from the Nehalem architecture on a 45 nm process. Benchmark data shows the Xeon winning every single head-to-head comparison, yet the margins are surprisingly narrow. The data reveals a story of architectural progress being less impactful than expected in raw compute, while the platform differences tell a much larger tale.

Head-to-Head Benchmarks

The Xeon W-2104 wins all six benchmark comparisons, but the margins are consistently slim. In Cinebench R15 multicore, the Xeon scores 470 against the i5-760's 466, a 0.9% difference. The single-core R15 test shows 66 versus 65, a 1.5% lead for the Xeon. Moving to Cinebench R20, the multicore result is 1960 for the Xeon and 1942 for the i5-760, again a 0.9% gap. The R20 single-core test shows 276 versus 273, a 1.1% advantage. In the newer Cinebench R23, the Xeon posts 4669 multicore and 659 single-core, while the i5-760 manages 4624 and 652, respectively, with deltas of 1% and 1.1%.

The pattern here is consistent: the Xeon W-2104 edges out the older chip in every workload, but never by more than 1.5%. This is remarkable when you consider the generation gap. The i5-760's boost clock of 3.33 GHz helps it stay competitive against the Xeon's fixed 3.20 GHz base clock. The Xeon's higher single-core scores suggest better instructions-per-clock (IPC) efficiency from the newer Skylake architecture, but the raw clock speed difference keeps the older chip within striking distance. The average benchmark scores reflect this closeness: the Xeon averages 1350, placing it in the 36th percentile of all CPUs, while the i5-760 averages 1337, sitting at the 35th percentile. Their nearest rival lists even overlap, with both being compared to the Intel Core i5-4590T and Intel Core i5-4670.

Where Each One Wins

Given that the Xeon W-2104 wins every single benchmark, the question of "where each one wins" is really about the margins and the contexts. The Xeon's largest advantage comes in Cinebench R15 single-core, where it leads by 1.5%. This indicates that for lightly-threaded tasks, the newer architecture's IPC advantage is most pronounced. The Xeon also shows a slight edge in R20 and R23 single-core tests at 1.1%, suggesting consistent superiority in single-threaded workloads.

The i5-760, despite losing all benchmarks, does not get blown out. Its best showing is in R15 and R20 multicore, where it trails by only 0.9%. This suggests that in heavily threaded workloads, the older chip's 4 cores and 4 threads are able to keep up reasonably well, likely due to its higher boost clock of 3.33 GHz versus the Xeon's non-existent boost. The i5-760 also wins in the sense of being a viable alternative for anyone on an older platform, given that its benchmark scores are so close. For a 2010 processor, posting scores within 1.5% of a 2017 workstation chip is a notable result, though the Xeon still claims victory in every category.

Architecture Differences

The architectural gap between these two is substantial. The Xeon W-2104 uses the Skylake-W architecture on a 14 nm process, while the i5-760 uses the Nehalem architecture (codename Lynnfield) on a 45 nm process. This represents a significant manufacturing node advantage for the Xeon, allowing for the 484 mm² die size versus the i5-760's 296 mm² die. The Xeon packs 4 cores with 64 KB of L1 cache per core and 1 MB of L2 per core, while the i5-760 also has 64 KB L1 per core but only 256 KB of L2 per core. The L3 cache is similar: 8.25 MB shared on the Xeon versus 8 MB shared on the i5-760. The Xeon's larger per-core L2 cache (1 MB versus 256 KB) likely contributes to its better single-core performance.

The i5-760 has 774 million transistors on its 296 mm² die, while the Xeon's transistor count is not listed. The Xeon uses DDR4 memory with a quad-channel bus, providing 85.3 GB/s of bandwidth, whereas the i5-760 uses DDR3 with a dual-channel bus and no listed bandwidth figure. The Xeon supports ECC memory, while the i5-760 does not. PCIe connectivity also differs significantly: the Xeon offers Gen 3 with 48 lanes (CPU only), while the i5-760 offers Gen 2 with 16 lanes (CPU only). These platform differences highlight the Xeon's workstation/server positioning versus the i5-760's desktop role.

Specification Differences

The two processors differ in several key specifications. The Xeon W-2104 has a base clock of 3.20 GHz with no boost clock, while the i5-760 has a base clock of 2.80 GHz and a boost clock of 3.33 GHz. The Xeon has a 120 W TDP, while the i5-760 has a 95 W TDP, meaning the newer chip consumes more power despite being on a smaller process node. They use different sockets: the Xeon uses Intel Socket 2066, while the i5-760 uses Intel Socket 1156. The Xeon was released in August 2017 with a launch MSRP of $255, while the i5-760 was released in July 2010 with no listed launch MSRP. The Xeon's market segment is Server/Workstation, while the i5-760 is Desktop. Both are end-of-life products with locked multipliers. The Xeon's part number is SR3LH, and the i5-760's is SLBRP.

FAQ

Q: Which processor has a higher base clock speed?

A: The Intel Xeon W-2104 has a base clock of 3.20 GHz, while the Intel Core i5-760 has a base clock of 2.80 GHz. However, the i5-760 has a boost clock of 3.33 GHz, which the Xeon lacks entirely.

Q: How much faster is the Xeon W-2104 in multi-core workloads?

A: In Cinebench R23 multicore, the Xeon scores 4669 versus the i5-760's 4624, a 1% difference. In Cinebench R20 multicore, the Xeon scores 1960 versus 1942, also a 0.9% difference.

Q: Do these processors have the same number of cores and threads?

A: Yes, both have 4 cores and 4 threads. This means they are both limited to 4 concurrent threads, which explains the relatively small performance gaps between them.

Q: Which processor supports ECC memory?

A: The Intel Xeon W-2104 supports ECC memory, while the Intel Core i5-760 does not. This makes the Xeon more suitable for workstation or server environments where data integrity is critical.

Q: What is the memory bandwidth difference between the two?

A: The Xeon W-2104 has a quad-channel memory bus with 85.3 GB/s bandwidth, while the i5-760 has a dual-channel memory bus with no listed bandwidth figure. The Xeon's memory subsystem is significantly more capable.

Q: How do these processors compare to their nearest rivals?

A: The Xeon W-2104 averages 1350, placing it 0.1% ahead of the Intel Core i5-7400T (1348) and 0.2% ahead of the Intel Core i5-4670 (1347). The i5-760 averages 1337, putting it 0.2% behind the Intel Core i5-4590T (1340) and 0.5% ahead of the Intel Core i5-4460S (1330).

The Verdict

The data points to a clear but narrow winner: the Intel Xeon W-2104 takes every benchmark, making it the superior performer in both single-core and multi-core tasks. If raw compute is the only criterion, the Xeon is the obvious choice, especially for users who need ECC memory support, quad-channel DDR4 bandwidth, or the 48 PCIe Gen 3 lanes that the i5-760 cannot offer. The Xeon's 36th percentile ranking versus the i5-760's 35th percentile reinforces this hierarchy, though the difference is marginal.

However, the i5-760 is not a bad option for its era. Its boost clock of 3.33 GHz helps it stay within 1.5% of the Xeon in every test, and its lower 95 W TDP makes it a more power-efficient choice. For someone already on an Intel Socket 1156 platform, upgrading to an i5-760 would cost nothing in platform terms, whereas moving to a Socket 2066 Xeon would require a full platform overhaul. The i5-760's lack of ECC and narrower memory bus are meaningful drawbacks for professional use, but for a desktop workload, the performance difference is almost negligible. The Xeon W-2104 is the better processor on paper and in practice, but the i5-760's resilience in benchmarks proves that architecture alone does not dictate performance.
