Intel Core i3-9100TE vs Intel Xeon E3-1240L v3 Comparison

The Intel Xeon E3-1240L v3 and Intel Core i3-9100TE are both low-power, four-core Intel parts, but they come from different eras and design philosophies. The Xeon E3-1240L v3 is a 25W Haswell-era server chip, while the Core i3-9100TE is a 35W Coffee Lake desktop processor. Benchmark results show a clear, consistent performance gap: the older Xeon wins all six head-to-head Cinebench comparisons, with margins ranging from 23.6% to 23.8%. The Xeon’s average benchmark score is 1396, compared to the i3’s 1386, and both sit at the 37th percentile of all CPUs. The data points to a surprising outcome: the older, lower-TDP Xeon is the faster chip in every measured metric, despite the i3’s newer architecture and higher clock speeds.

Where Each One Wins

The benchmark data is unambiguous: the Intel Xeon E3-1240L v3 wins every single test in the head-to-head comparison. It claims all six Cinebench victories, covering both single-core and multi-core workloads across R15, R20, and R23 versions. The Xeon’s multi-core advantage is substantial; for example, in Cinebench R23 multi-core, it scores 4827 against the i3-9100TE’s 3900, a 23.8% lead. This makes the Xeon the clear choice for heavily threaded rendering tasks, where its eight threads (4 cores, 8 threads) can be fully utilized.

The Core i3-9100TE, by contrast, has zero wins in the head-to-head data. It does not outperform the Xeon in any single benchmark. However, the i3 is not without its own strengths. It features integrated UHD Graphics 630, whereas the Xeon has no integrated graphics at all, meaning the i3 can power a display without a discrete GPU. The i3 also supports DDR4 memory with a higher peak bandwidth of 38.4 GB/s, compared to the Xeon’s DDR3 at 25.6 GB/s. For a system needing a simple, self-contained desktop build with modern memory, the i3 holds an advantage in platform features, even if it loses in raw compute.

The Xeon’s wins are not just narrow victories; they are consistent and significant. In single-core tests, the Xeon leads by 23.6% in R15, 23.8% in R20, and 23.8% in R23. This uniformity across different Cinebench versions suggests a structural advantage, not a workload-specific fluke. For users prioritizing CPU throughput, the Xeon is the definitive winner. For users prioritizing platform integration, the i3’s integrated graphics and DDR4 support are its only redeeming features.

Architecture Differences

The two processors are built on fundamentally different architectures and process nodes. The Xeon E3-1240L v3 uses the Haswell architecture, specifically the Haswell-WS codename, fabricated on Intel’s 22 nm process. It packs 1,400 million transistors into a 160 mm² die. The Core i3-9100TE uses the newer Coffee Lake architecture, on a 14 nm process, with a smaller 126 mm² die size. Despite the newer node, the i3 lacks transistor count data in the fact pack, making direct comparisons on that front impossible.

Cores and threads are a critical differentiator. Both parts have 4 physical cores, but the Xeon supports Hyper-Threading, giving it 8 threads. The i3-9100TE is limited to 4 threads, with no Hyper-Threading. This explains the Xeon’s multi-core dominance. Cache configurations also differ: the Xeon has 8 MB of shared L3 cache, while the i3 has 6 MB. Both have identical L1 (64 KB per core) and L2 (256 KB per core) caches.

Memory support is a major generational split. The Xeon uses DDR3 memory in a dual-channel configuration, with a memory bandwidth of 25.6 GB/s. The i3 uses DDR4, also dual-channel, but with a higher bandwidth of 38.4 GB/s. Both support ECC memory, which is notable for the i3 since it is a desktop part. PCIe support is identical: Gen 3 with 16 lanes from the CPU. The Xeon has no integrated graphics, while the i3 includes UHD Graphics 630. The Xeon targets the server/workstation market segment, while the i3 is a desktop part. Both are end-of-life products, with the Xeon released in May 2014 and the i3 in March 2019.

Clock speeds favor the i3 on paper. The i3 has a 2.20 GHz base clock and a 3.20 GHz boost clock, compared to the Xeon’s 2.00 GHz base and 3.00 GHz boost. Despite this, the Xeon wins every benchmark, highlighting the efficiency of its Haswell design and its thread advantage. The Xeon also has a much lower TDP of 25W versus the i3’s 35W, making it more power-efficient per unit of performance.

Head-to-Head Benchmarks

The Cinebench results are remarkably consistent, showing a near-uniform 23.7% advantage for the Xeon across all tests. In Cinebench R15 multi-core, the Xeon scores 486 against the i3’s 393, a 23.7% delta. The single-core R15 result is similar: 68 for the Xeon versus 55 for the i3, a 23.6% lead. This pattern holds in R20, where the Xeon’s multi-core score is 2027 versus 1638 (23.7% delta), and its single-core score is 286 versus 231 (23.8% delta).

The R23 results reinforce the trend. In multi-core, the Xeon hits 4827, beating the i3’s 3900 by 23.8%. In single-core, the Xeon scores 681 against 550, again a 23.8% margin. The fact that the Xeon wins single-core tests by the same margin as multi-core tests is telling. It suggests that the Xeon’s advantage is not just about having more threads, but also about superior per-core performance in these workloads, despite the i3’s higher clock speeds.

The i3 does have one benchmark category not present for the Xeon: Geekbench. The i3 scores 3214 in Geekbench multi-core and 1105 in single-core. However, since the Xeon has no Geekbench scores in the fact pack, this cannot be used for a direct comparison. The head-to-head data only includes Cinebench tests, all of which the Xeon wins. The Xeon’s average benchmark score is 1396, slightly higher than the i3’s 1386. For context, the Xeon’s nearest rivals are the Intel Core i5-6500TE (avg 1399, -0.2% delta) and the Intel Xeon E3-1220 v5 (avg 1401, -0.4% delta). The i3’s rivals include the AMD Opteron 6274 (avg 1387, -0.1% delta) and the Intel Core i7-3615QE (avg 1381, 0.4% delta).

The Verdict

The data makes a decisive case for the Intel Xeon E3-1240L v3. It wins every benchmark in the comparison, with a consistent 23.6% to 23.8% lead over the Core i3-9100TE in both single-core and multi-core tests. Its 8 threads, larger 8 MB L3 cache, and lower 25W TDP make it a superior choice for any compute-intensive workload. The Xeon’s average benchmark score of 1396 is higher than the i3’s 1386, and its nearest rivals are all within a narrow band, indicating it is a solid performer in its class.

The Core i3-9100TE is not without merit, but its advantages are purely platform-based, not performance-based. It offers integrated UHD Graphics 630, which the Xeon lacks entirely, making it suitable for a basic desktop system without a discrete GPU. It also supports faster DDR4 memory with 38.4 GB/s bandwidth, which could benefit memory-sensitive applications. However, in raw CPU compute, the i3 is the clear underdog, scoring 3900 in R23 multi-core versus the Xeon’s 4827.

For a user building a system where CPU performance is the priority, the Xeon E3-1240L v3 is the obvious pick, despite being five years older. Its lower TDP and higher thread count make it an efficient workhorse. For a user needing a self-contained desktop with integrated graphics and modern memory, the i3-9100TE is the only option, but they must accept a significant performance deficit. The verdict is straightforward: the Xeon wins on performance, and the i3 wins on platform features. Choose accordingly based on whether you need raw compute or integrated capability.
