Intel Core i3-10105T vs Intel Xeon E-2124G Comparison

The Verdict

The Intel Core i3-10105T and Intel Xeon E-2124G are both 4-core desktop-class processors with integrated graphics, but they target different priorities. The recorded data splits the two clearly: the Core i3-10105T wins 6 of the 8 head-to-head benchmark comparisons, all of them in Cinebench workloads, while the Xeon E-2124G wins the two Geekbench tests. The Core i3-10105T takes the overall win count, but the margin of victory in its favored tests is modest, around 9.1% to 9.3% across Cinebench R15, R20, and R23, both multi-core and single-core. The Xeon E-2124G counters with a larger 14.4% lead in Geekbench multi-core and a 12% lead in Geekbench single-core.

The Core i3-10105T is the better choice for users running Cinebench-style render workloads, where its 8 threads give it a consistent edge over the Xeon's 4 threads. Its 35 W TDP also positions it as a low-power part, while the Xeon E-2124G draws 71 W. The Xeon E-2124G, however, is the pick for Geekbench-focused tasks, and it is the only one of the two that supports ECC memory, making it the logical option for workstation or server environments where data integrity matters. The Xeon also carries a server/workstation market segment in the database, whereas the Core i3 is a desktop part. The Core i3 remains in active production; the Xeon is end-of-life. The launch MSRP for the Core i3-10105T is $134, and for the Xeon E-2124G it is $218.

Architecture Differences

The Core i3-10105T is built on the Comet Lake architecture, with the codename Comet Lake-R, and belongs to the Core 10th Gen series. The Xeon E-2124G uses the Coffee Lake architecture, with the codename Coffee Lake-S WS, and belongs to the Xeon E-2100 series. Both are manufactured on Intel's 14 nm process node, and both are fabricated by Intel. The die size is listed only for the Xeon E-2124G at 126 mm²; no die size is recorded for the Core i3-10105T.

The fundamental architectural difference lies in threading and cache configuration. The Core i3-10105T has 4 cores and 8 threads, enabling simultaneous multi-threading. The Xeon E-2124G has 4 cores and 4 threads, with no hyper-threading support. This explains the Core i3's advantage in multi-threaded Cinebench tests, where additional logical threads can be utilized. The Xeon E-2124G compensates with a larger L3 cache: 8 MB shared, versus 6 MB shared for the Core i3. Both share the same L1 cache at 64 KB per core and L2 cache at 256 KB per core.

The integrated graphics also differ. The Core i3-10105T carries UHD Graphics 630, while the Xeon E-2124G carries HD Graphics P630. Both are Intel integrated solutions, but the Xeon's P630 variant is typically aimed at professional use cases, consistent with its server/workstation market segment. The Core i3 is marked as a Desktop segment part, while the Xeon is marked as Server/Workstation.

Memory support is identical in type and channel configuration: both support DDR4 memory in a dual-channel layout, and both record a memory bandwidth of 42.7 GB/s. The key difference is ECC support, which is present on the Xeon E-2124G and absent on the Core i3-10105T. PCIe connectivity is the same on paper: Gen 3 with 16 lanes (CPU only) for both.

Production status separates the two further. The Core i3-10105T is listed as Active, with a release date of 2021-03-15. The Xeon E-2124G is listed as End-of-life, with a release date of 2018-07-11. Neither processor has an unlocked multiplier. The part numbers are SRH3R for the Core i3 and SR3WL for the Xeon.

Boost clock is 3.90 GHz on the Core i3 and 4.50 GHz on the Xeon. TDP is 35 W on the Core i3 and 71 W on the Xeon.

Socket types differ: the Core i3 uses Intel Socket 1200, the Xeon uses Intel Socket 1151. The architecture names differ, Comet Lake vs Coffee Lake, and the codenames differ, Comet Lake-R vs Coffee Lake-S WS. The generation labels are "Core i3 (Comet Lake)" for the Core i3 and "Xeon E (Coffee Lake)" for the Xeon.

Cache sizes differ at the L3 level: 6 MB shared for the Core i3, 8 MB shared for the Xeon. The Xeon has a listed die size of 126 mm²; no die size is recorded for the Core i3. ECC memory support is true for the Xeon and false for the Core i3. Integrated graphics differ: UHD Graphics 630 for the Core i3, HD Graphics P630 for the Xeon.

Market segments differ: Desktop for the Core i3, Server/Workstation for the Xeon. Production status differs: Active for the Core i3, End-of-life for the Xeon. Release dates differ: 2021-03-15 for the Core i3, 2018-07-11 for the Xeon. Launch MSRP differs: $134 for the Core i3, $218 for the Xeon. The average benchmark score favors the Core i3 at 2058 vs 2034 for the Xeon. The percentile vs all CPUs is 46 for the Core i3 and 45 for the Xeon.

The nearest rivals in the database also differ. For the Core i3-10105T, the closest competitors are the Intel Core i7-8705G (2058, 0% delta), the AMD Ryzen 5 3400G (2059, -0.1% delta), the AMD Ryzen 3 3100 (2055, 0.2% delta), and the Intel Xeon E3-1585 v5 (2067, -0.4% delta). For the Xeon E-2124G, the closest rivals are the AMD Ryzen 5 4500U (2035, 0% delta), the Intel Core i7-3960X (2037, -0.1% delta), the Intel Core i7-5775R (2031, 0.1% delta), and the Intel Xeon E3-1240 v5 (2030, 0.2% delta).

Head-to-Head Benchmarks

The head-to-head benchmark set contains 8 tests, and the outcomes are split along workload lines. The Core i3-10105T wins all 6 Cinebench tests. In Cinebench R15 multi-core, the Core i3 scores 670 against the Xeon's 613, a 9.3% advantage. In Cinebench R15 single-core, the Core i3 scores 94 against 86, also 9.3%. The pattern repeats in Cinebench R20: 2795 vs 2558 in multi-core, a 9.3% delta, and 394 vs 361 in single-core, a 9.1% delta. Cinebench R23 shows the same consistency: 6656 vs 6092 in multi-core, 9.3%, and 939 vs 860 in single-core, 9.2%.

The Xeon E-2124G wins both Geekbench tests, and by larger margins. In Geekbench multi-core, the Xeon scores 4263 against the Core i3's 3649, a 14.4% lead. In Geekbench single-core, the Xeon scores 1438 against 1265, a 12% lead. These wins are substantial enough to flip the average benchmark score narrative only slightly: the Core i3 still leads on average (2058 vs 2034), but the Geekbench results show that the Xeon is not without merit.

The delta percentages tell a clear story. The Core i3's wins are nearly uniform, clustering between 9.1% and 9.3% across all six Cinebench tests. That uniformity suggests the advantage comes from a consistent architectural trait, likely the additional 4 threads. The Xeon's wins are larger in percentage terms, 12% and 14.4%, but they are confined to a single benchmark suite. The overall win count is 6 for the Core i3 and 2 for the Xeon.

For a buyer choosing between these two, the data points to the Core i3-10105T for Cinebench-style rendering and multi-threaded productivity, especially given its lower 35 W TDP and active production status. The Xeon E-2124G makes sense for Geekbench-heavy workflows and for systems requiring ECC memory, despite its higher 71 W TDP and end-of-life status. The benchmark data does not declare a universal winner; it declares a workload-dependent one.
