The Intel Xeon E5-1630 v4 and the Intel Core i5-1035G4 are two very different processors that, according to the benchmark data, land in nearly the same performance tier. Both chips feature 4 cores and 8 threads, and their average benchmark scores are almost identical: the Xeon averages 1869 points, while the Core i5 averages 1861 points. This places both in the 42nd percentile of all CPUs, and their nearest-rival lists are nearly mirror images of each other, with the Xeon holding a 0.4% lead over the Core i5 in overall average score. The data tells a story of two architectures solving the same problem in different ways, with the desktop Xeon relying on high power and a large cache, while the mobile Core i5 uses a smaller, more efficient design.

Head-to-Head Benchmarks

The head-to-head results are remarkably one-sided, with the Intel Xeon E5-1630 v4 winning all six benchmark comparisons. However, the margins are extremely narrow, making this a case of consistent, yet marginal, superiority rather than a dominant victory. In Cinebench R15, the Xeon scores 651 points in the multicore test against the Core i5's 648 points, a differential of just 0.5%. The single-core R15 result is a perfect tie at 91 points for both processors, with the Xeon listed as the winner due to a 0% delta.

Moving to Cinebench R20, the pattern continues. The Xeon posts a multicore score of 2714, while the Core i5 achieves 2703, giving the Xeon a 0.4% edge. In the single-core R20 test, the Xeon scores 383 versus the Core i5's 381, a 0.5% advantage. The most recent Cinebench R23 results show the same trend: the Xeon leads in multicore with 6464 points against 6436 points (0.4% delta), and in single-core with 912 points against 908 points (0.4% delta).

What is striking is not the magnitude of the wins but their consistency. The Xeon never loses a single test, yet the largest margin of victory is a mere 0.5%. This suggests that for any given workload, the two chips are effectively interchangeable in raw compute performance, with the Xeon holding a slight, repeatable edge. The data shows the Xeon's advantage is most pronounced in the R15 multicore test at 0.5%, while the R20 multicore and R23 tests all show a 0.4% gap. The single-core R15 tie indicates that neither architecture has a fundamental advantage in lightly-threaded tasks.

Q: What is the difference in their L3 cache sizes?

A: The Intel Xeon E5-1630 v4 has a larger L3 cache of 10 MB (shared), while the Intel Core i5-1035G4 has a 6 MB (shared) L3 cache. This is one of the key architectural differences between the two.

Q: Which CPU has a higher TDP?

A: The Intel Xeon E5-1630 v4 has a much higher TDP of 140, while the Intel Core i5-1035G4 has a TDP of 15. This reflects the Xeon's desktop-oriented design versus the Core i5's mobile focus.

Architecture Differences

The architectural divide between these two chips is substantial, starting with their process nodes. The Xeon E5-1630 v4 is built on a 14 nm process using the Broadwell-EP architecture, while the Core i5-1035G4 uses a 10 nm process with the Ice Lake-U architecture (specifically Sunny Cove-U). This generational leap is visible in the die sizes: the Xeon has a 246 mm² die with 3,400 million transistors, while the Core i5 is much smaller at 123 mm². The Xeon's larger die is due to its server heritage, despite having the same core count as the mobile chip.

Cache hierarchies also differ significantly. The Xeon provides 64 KB of L1 cache per core, while the Core i5 offers 80 KB per core. Both share the same 256 KB per core L2 cache. The biggest difference is in the shared L3 cache: the Xeon has 10 MB, while the Core i5 has only 6 MB. This larger pool of shared cache on the Xeon likely contributes to its slight edge in the multicore benchmarks, as it can hold more working data closer to the cores.

Memory architecture is another major separator. The Xeon supports quad-channel DDR4 memory with a theoretical bandwidth of 76.8 GB/s, and it supports ECC memory. In contrast, the Core i5 uses dual-channel DDR4 with a bandwidth of 51.2 GB/s and does not support ECC. The Xeon also provides 40 PCIe Gen 3 lanes from the CPU, whereas the Core i5 simply lists "Gen 3" without a specific lane count. The Xeon includes no integrated graphics, while the Core i5 features Iris Plus graphics, reflecting their different intended use cases. Finally, the Xeon is end-of-life and was released in 2016, while the Core i5 is active and was released in 2019.

Specification Differences

The specification sheets reveal stark contrasts in nearly every category except core count and threading. The Xeon E5-1630 v4 has a base clock of 3.70 GHz and a boost clock of 4.00 GHz, while the Core i5-1035G4 has a base clock of 1100.00 and a boost clock of 3.70 GHz. The Xeon's TDP of 140 is nearly ten times higher than the Core i5's 15, underscoring the difference between a desktop part and a mobile part.

Sockets are incompatible: the Xeon uses Intel Socket 2011-3, whereas the Core i5 uses Intel BGA 1526, meaning they are not interchangeable in any system. The Xeon is a 14 nm Broadwell part, and the Core i5 is a 10 nm Ice Lake part. Memory support differs in bus width, with the Xeon using quad-channel and the Core i5 using dual-channel, resulting in different memory bandwidths (76.8 GB/s versus 51.2 GB/s). ECC memory support is present on the Xeon but absent on the Core i5. The Xeon has no integrated graphics, while the Core i5 has Iris Plus graphics. The Xeon has a launch MSRP of $406, while the Core i5 has no listed launch MSRP. The Xeon's part number is SR2PF, and the Core i5's is SRGKK.

Where Each One Wins

The benchmark data shows the Xeon E5-1630 v4 winning all six head-to-head tests, but the practical implications are nuanced. The Xeon wins in every Cinebench test because of its slightly higher clock speeds and larger cache, but the margins are so small that the Core i5 is not disadvantaged in any meaningful way for most workloads. The Xeon's wins are most pronounced in multicore tests, where its 0.4% to 0.5% leads suggest a minor advantage in heavily threaded rendering tasks.

The Core i5-1035G4 does not win any benchmark, but it has distinct advantages outside of raw compute. Its integrated Iris Plus graphics make it suitable for systems without a discrete GPU, which the Xeon cannot offer. Its 15 TDP makes it far more suitable for thin-and-light laptops, while the Xeon's 140 TDP requires substantial cooling and power delivery. The Core i5's smaller die size and 10 nm process indicate a more modern, power-efficient design, even though it does not translate into a performance win in these specific tests.

The Xeon's quad-channel memory support and ECC capability make it a better fit for memory-intensive professional workloads where data integrity is critical. The Core i5's dual-channel memory is sufficient for mainstream tasks but lacks the bandwidth headroom of the Xeon. In a desktop workstation context, the Xeon's 40 PCIe lanes allow for more expansion cards, while the Core i5's unspecified PCIe configuration is typical of a mobile part with limited expansion options.

The Verdict

The data indicates that the Intel Xeon E5-1630 v4 is the faster processor in a strict benchmark sense, winning all six head-to-head comparisons. However, the margins are tiny, ranging from 0% to 0.5%, which means the real-world performance difference is negligible for most applications. The Xeon's wins are consistent, which suggests a slight architectural edge, but not one that would be noticeable without meticulous measurement.

The choice between these two comes down to platform and use case, not raw speed. The Xeon E5-1630 v4 is the clear pick for a desktop workstation that requires ECC memory, quad-channel bandwidth, and a high-TDP socket that can support a powerful cooling solution. Its 10 MB L3 cache and 40 PCIe lanes are assets for server-like workloads. The Core i5-1035G4 is the only viable option for a mobile platform, given its BGA socket, 15 TDP, and integrated graphics. It sacrifices cache, memory bandwidth, and ECC support for efficiency and portability, and the benchmark results show that sacrifice costs it less than 1% performance in Cinebench tests.

For a user building a new desktop system today, the Xeon's end-of-life status and 2016 release date are drawbacks, but its benchmark scores remain competitive with the 2019 Core i5. For a user seeking a modern, active mobile processor, the Core i5 is the only choice in this comparison. The verdict is simple: if the platform demands a socketed, high-power, ECC-capable CPU, the Xeon wins. If the platform demands a low-power, integrated-graphics mobile chip, the Core i5 wins. Neither chip can substitute for the other, and the benchmark parity makes the platform the deciding factor.
