CPU Comparison

The Intel Xeon E5-4610 v3 and the Intel Core i5-5675C represent two fundamentally different interpretations of Intel’s mid-2010s roadmap. The Xeon is a 10-core, 20-thread Haswell-EP server processor built for multi-socket workstations, while the i5-5675C is a 4-core, 4-thread Broadwell desktop chip with integrated Iris Pro Graphics. The benchmark data shows a decisive sweep: the Xeon wins all six head-to-head Cinebench tests, with an average benchmark score of 1777 against the i5’s 1759. Both processors sit at the 41st percentile of all CPUs, indicating they occupy a similar overall performance tier despite their architectural divergence.

Head-to-Head Benchmarks

The most striking pattern in the head-to-head results is the uniformity of the Xeon’s victory margin. Across all three Cinebench generations (R15, R20, and R23), the Xeon E5-4610 v3 beats the Core i5-5675C by exactly 25.1% in both multi-core and single-core tests. This consistency suggests the gap is structural rather than workload-dependent, it reflects the Xeon’s superior per-core architecture and memory subsystem, not just its higher core count.

In Cinebench R15 multi-core, the Xeon scores 619 against the i5’s 495. The 25.1% delta translates to 124 points, a substantial margin that underscores the Xeon’s thread-count advantage. The single-core R15 result is even more lopsided in relative terms, with the Xeon at 87 and the i5 at 69, again a 26.1% delta, which is the largest single-core gap in the entire comparison. This is notable because single-core performance is typically where lower-clocked server chips lose ground to desktop parts; here, the Xeon’s 1700 MHz base clock still outperforms the i5’s 3.10 GHz base and 3.60 GHz boost in Cinebench’s single-threaded test.

The R20 results follow the same script: Xeon 2580 vs. i5 2063 multi-core, and Xeon 364 vs. i5 291 single-core. Both deltas sit at 25.1%. The R23 results are the most telling for modern workloads, the Xeon hits 6144 multi-core while the i5 manages 4912, a difference of 1232 points. In R23 single-core, the Xeon scores 867 against the i5’s 693, maintaining the 25.1% gap.

What the data does not show is any test where the i5-5675C closes the gap or wins. The i5’s only additional benchmark data comes from Geekbench, where it scores 4159 multi-core and 1388 single-core, but the Xeon has no Geekbench results in the FACT PACK, so these cannot be compared directly. The head-to-head table lists winsA as 6 and winsB as 0, making the outcome unambiguous.

The Verdict

The data presents a clear hierarchy: the Intel Xeon E5-4610 v3 is the superior processor in every measured Cinebench metric. The 25.1% advantage across all six tests is a statistical outlier in its consistency, few CPU comparisons show such uniform deltas across different benchmark generations and thread counts. The Xeon’s average benchmark score of 1777 places it 0.2% ahead of the Intel Xeon E5-2637 v3 and 0.4% ahead of the Intel Core i7-4870HQ, while the i5-5675C’s 1759 average puts it 0.2% behind the Intel Xeon E3-1241 v3 and 0.4% behind the AMD Ryzen 5 2400GE.

For server and workstation workloads, the Xeon is the only defensible choice. Its 10 cores and 20 threads provide the parallel throughput that Cinebench multi-core rewards, and its 25 MB of shared L3 cache dwarfs the i5’s 4 MB. The Xeon also supports ECC memory and quad-channel DDR4 with 51.2 GB/s of bandwidth, compared to the i5’s non-ECC dual-channel DDR3 at 25.6 GB/s. If the task involves rendering, simulation, or any heavily threaded application, the Xeon’s 6144 R23 multi-core score versus the i5’s 4912 is a 25.1% advantage that scales directly to job completion time.

The i5-5675C is not without merit, but its wins are outside the measured benchmarks. It has an unlocked multiplier, integrated Iris Pro Graphics 6200, and a 65W TDP versus the Xeon’s 105W. For a desktop user who needs modest multi-core performance and does not require ECC or server-grade memory bandwidth, the i5 is a viable part, but the data does not support any claim of performance parity in Cinebench.

Where Each One Wins

Intel Xeon E5-4610 v3 wins on:

• All Cinebench multi-core tests: R15 (619 vs. 495), R20 (2580 vs. 2063), R23 (6144 vs. 4912).
• All Cinebench single-core tests: R15 (87 vs. 69), R20 (364 vs. 291), R23 (867 vs. 693).
• Memory bandwidth: 51.2 GB/s quad-channel DDR4 vs. 25.6 GB/s dual-channel DDR3.
• ECC memory support: present on the Xeon, absent on the i5.
• PCIe lanes: 40 lanes (CPU only) versus 16 lanes.
• Cache capacity: 25 MB shared L3 vs. 4 MB shared L3.

Intel Core i5-5675C wins on:

• Integrated graphics: Iris Pro Graphics 6200 is included; the Xeon has none.
• Power efficiency: 65W TDP versus 105W.
• Overclocking: unlocked multiplier versus locked on the Xeon.
• Socket flexibility: Intel Socket 1150 is a mainstream desktop platform, while the Xeon requires Intel Socket 2011-3.
• Production status: the i5 is listed as Active, while the Xeon is End-of-life.

The i5’s Geekbench scores (4159 multi-core, 1388 single-core) are not directly comparable to the Xeon, but they do provide a reference point for its general performance, the multi-core score is roughly 68% of the R23 multi-core score, suggesting the i5 is a capable mid-range desktop chip.

Architecture Differences

The two processors diverge at nearly every architectural level. The Xeon E5-4610 v3 uses the Haswell-EP architecture on a 22 nm process node, with 2,600 million transistors on a 356 mm² die. The i5-5675C uses the Broadwell architecture on a 14 nm process node, with a 182 mm² die size (transistor count is not listed). This process shrink explains the i5’s lower 65W TDP despite its higher clock speeds.

Cores and threads present the starkest contrast: 10 cores and 20 threads on the Xeon versus 4 cores and 4 threads on the i5. The Xeon’s base clock is 1700 MHz with no boost clock listed, while the i5 runs at 3.10 GHz base and 3.60 GHz boost. Despite the i5’s higher clocks, the Xeon’s single-core Cinebench scores are 25.1% higher, a result that points to the Xeon’s superior IPC (instructions per clock) in this workload, likely aided by its larger 25 MB L3 cache versus the i5’s 4 MB.

Cache hierarchies differ significantly. Both have 64 KB L1 and 256 KB L2 per core, but the Xeon’s shared L3 is 25 MB compared to the i5’s 4 MB. This 6.25x difference in L3 capacity is critical for server workloads that exhibit high data reuse across threads.

Memory support is another major split. The Xeon uses quad-channel DDR4 with 51.2 GB/s bandwidth and ECC support, while the i5 uses dual-channel DDR3 with 25.6 GB/s and no ECC. The Xeon also provides 40 PCIe Gen 3 lanes (CPU only) versus the i5’s 16 lanes, making the Xeon the clear choice for high-bandwidth peripherals like multiple GPUs or NVMe storage arrays.

The i5 counters with an unlocked multiplier for overclocking, integrated Iris Pro Graphics 6200, and a mainstream Socket 1150 platform. The Xeon targets Socket 2011-3, which is exclusive to server and workstation chipsets. The Xeon’s launch MSRP is $1219, while the i5’s is $276, but the Xeon is End-of-life, whereas the i5 remains Active. The Xeon’s 22 nm process and 2,600 million transistors reflect an older, larger design, while the i5’s 14 nm process and 182 mm² die show Intel’s shift toward density and efficiency in the desktop segment.
