CPU Comparison

The Intel Xeon E5-1630 v3 and Intel Core i3-9100 are both quad-core processors from Intel, but they target fundamentally different platforms and eras. The Xeon E5-1630 v3 is a Haswell-EP server/workstation part from 2014, while the Core i3-9100 is a Coffee Lake desktop chip from 2018. Benchmark data shows the Xeon wins every single head-to-head Cinebench test, yet the i3 features a higher boost clock and a much newer architecture. This comparison is a study in how platform advantages can offset generational improvements.

Where Each One Wins

The data is unambiguous: the Xeon E5-1630 v3 wins all six recorded Cinebench benchmarks. Its victories range from a 12% delta in Cinebench R20 multi-core to a 12.7% delta in Cinebench R15 single-core. The Xeon’s performance advantage is consistent across both single-threaded and multi-threaded workloads, which suggests it is not merely a matter of core count but a combination of architecture and memory subsystem strength.

The Core i3-9100 has no benchmark wins in this dataset. Its only potential advantages lie in platform attributes rather than measured performance. It has a higher boost clock of 4.20 GHz versus the Xeon’s 3.80 GHz, and it includes integrated graphics (UHD Graphics 630) while the Xeon has none. The i3 also draws far less power on paper (65W TDP versus 140W), but that is a specification, not a benchmark result.

For software that relies heavily on Cinebench-style rendering loads, the Xeon is the clear performer. The i3’s edge would be in scenarios where integrated graphics are needed or where a lower-power, newer platform is desirable, but strictly from the benchmark data, the Xeon wins every measurable test.

Architecture Differences

The two processors come from different architectural generations and process nodes. The Xeon E5-1630 v3 uses the Haswell-EP architecture on a 22 nm process, with a die size of 356 mm² and 2,600 million transistors. The Core i3-9100 is built on the Coffee Lake architecture using a 14 nm process, with a much smaller die size of 126 mm². The transistor count for the i3 is not provided.

Cache configurations differ significantly. Both have 64 KB L1 and 256 KB L2 per core, but the Xeon has 10 MB of shared L3 cache while the i3 has only 6 MB. This 4 MB difference in L3 could contribute to the Xeon’s consistent lead in single-core tests, as larger caches often reduce memory latency for frequently accessed data.

Memory support is another major divergence. The Xeon supports quad-channel DDR4 with a memory bandwidth of 68.3 GB/s, while the i3 supports dual-channel DDR4 with 38.4 GB/s. That is nearly a 78% advantage in theoretical memory bandwidth for the Xeon. Both support ECC memory, but the Xeon’s platform (Socket 2011-3) is designed for server/workstation workloads, whereas the i3’s Socket 1151 is mainstream desktop.

PCIe lanes also differ: the Xeon provides 40 CPU lanes of Gen 3, while the i3 offers only 16. The Xeon has no integrated graphics, while the i3 includes Intel UHD Graphics 630. The Xeon’s TDP is 140W versus 65W for the i3, reflecting the former’s power-hungry server heritage.

The Verdict

From the benchmark data alone, the Intel Xeon E5-1630 v3 is the faster processor in every Cinebench test. It leads by 12.1% to 12.7% across R15, R20, and R23, in both single-core and multi-core runs. If raw rendering performance is your only criterion, the Xeon wins without question.

However, the Core i3-9100 is not without merit. It offers integrated graphics, a higher boost clock, and a much lower TDP. Its 14 nm process node is newer than the Xeon’s 22 nm, which typically means better efficiency per clock. The i3 also has a launch MSRP of $122, which you may record as a reference point, though we do not discuss value here.

Who should pick which? If you are building a system that requires ECC memory, quad-channel bandwidth, or 40 PCIe lanes, the Xeon E5-1630 v3 is the only option that fits. If you need integrated graphics or a low-power desktop chip, the i3-9100 is the practical choice. For pure compute performance as measured by Cinebench, the Xeon is superior, but its platform demands are far more specialized.

FAQ

A: Both have 4 cores, but the Xeon E5-1630 v3 has 8 threads while the Core i3-9100 has 4 threads.

Q: Does the Core i3-9100 ever beat the Xeon in any benchmark?

A: No. In the head-to-head data, the Xeon wins all 6 Cinebench tests, with deltas ranging from 12% to 12.7%.

Q: What is the memory bandwidth difference?

Head-to-Head Benchmarks

The Xeon E5-1630 v3 dominates every head-to-head benchmark. In Cinebench R15 multi-core, the Xeon scores 635 versus the i3’s 566, a 12.2% advantage. The single-core R15 test shows a similar story: 89 versus 79, a 12.7% lead for the Xeon.

Moving to Cinebench R20, the Xeon scores 2647 in multi-core versus 2361 for the i3 (12.1% delta), and 373 versus 333 in single-core (12% delta). The pattern repeats in Cinebench R23, where the Xeon achieves 6303 multi-core versus 5622 (12.1% delta) and 889 single-core versus 793 (12.1% delta).

The consistency of these deltas, all between 12% and 12.7%, suggests a systematic advantage rather than a workload-specific quirk. The Xeon’s larger L3 cache (10 MB vs 6 MB) and quad-channel memory bandwidth (68.3 GB/s vs 38.4 GB/s) likely provide the foundation for this lead. The i3’s higher boost clock of 4.20 GHz versus 3.80 GHz is not enough to overcome these platform-level advantages.

Interestingly, the i3-9100 has additional Geekbench scores (3403 multi-core, 1290 single-core) that are not part of the head-to-head comparison, so they cannot be directly compared against the Xeon. The available data shows a clean sweep for the Xeon.
