# Intel Core i3-10100 vs Intel Core i3-1315UE

The Intel Core i3-10100 and Intel Core i3-1315UE occupy the same average benchmark tier, separated by a mere 0.2% in aggregate scoring, yet they are fundamentally different processors. The 10100 is a 4-core, 8-thread desktop part from Comet Lake, while the 1315UE is a 6-core, 8-thread mobile chip from Raptor Lake-U. Despite the 1315UE winning five of six head-to-head benchmarks, the average scores land nearly identical at 1742 for the 10100 and 1739 for the 1315UE. This paradox resolves when examining the benchmark distribution: the 10100's scores come from a broader suite including 3DMark and Geekbench, where it holds its own, while the 1315UE's data is exclusively from Cinebench, where it dominates massively. The percentile ranking for both is 41, placing them in the same performance bracket among all CPUs.

Where Each One Wins

The Intel Core i3-1315UE wins decisively in every multi-threaded Cinebench test, and it also takes the lead in Cinebench R20 and R23 single-core tests. The most striking result is Cinebench R23 multi-core, where the 1315UE scores 6013 against the 10100's 2564, a 57.4% advantage. This gap repeats almost exactly across Cinebench R15 multi-core (606 vs 258), R20 multi-core (2525 vs 1076), and R23 multi-core. The 1315UE also wins Cinebench R20 single-core with 356 versus 152, a 57.3% delta, and Cinebench R23 single-core with 849 versus 362, another 57.4% delta. These are not marginal wins; they represent a generational leap in single-thread efficiency and multi-core throughput.

The Intel Core i3-10100 wins only one head-to-head benchmark: Cinebench R15 single-core, scoring 88 against the 1315UE's 85, a 3.5% advantage. This is a narrow victory in an older benchmark, suggesting the 10100's Comet Lake architecture retains a slight edge in that specific legacy workload. However, the 10100's broader benchmark suite reveals strengths not captured in the head-to-head comparison. In 3DMark, the 10100 scores 3235 in the 16-thread test, 1361 in the 2-thread test, 2357 in the 4-thread test, 3193 in the 8-thread test, 3185 at max threads, and 705 single-thread. In Geekbench, it reaches 4495 multi-core and 1350 single-core. These scores, absent from the 1315UE's data, contribute to the near-identical average benchmark scores and indicate the 10100 is a more balanced performer across diverse workloads.

The Verdict

The data clearly separates these two CPUs by use case. For anyone running multi-threaded rendering or content creation workloads, the Intel Core i3-1315UE is the overwhelming choice. Its Cinebench R23 multi-core score of 6013 is more than double the 10100's 2564, and the same 57.4% advantage holds across R15 and R20 multi-core tests. Single-core performance in Cinebench R20 and R23 also favors the 1315UE by the same margin, meaning it is faster in both lightly-threaded and heavily-threaded modern workloads. The 1315UE also operates at a 15W TDP versus the 10100's 65W, making it drastically more power-efficient while delivering superior performance in Cinebench.

The Intel Core i3-10100 is the pick only if legacy single-core performance in Cinebench R15 matters, where it edges ahead by 3.5%. Its desktop socket (Intel Socket 1200) and 16 PCIe Gen 3 lanes also make it suitable for systems requiring discrete GPU expansion, while the 1315UE uses a BGA 1744 socket with 8 PCIe Gen 4 lanes. The 10100's 3DMark and Geekbench scores, which are not available for the 1315UE, suggest it handles gaming and general productivity more consistently. However, given that the 1315UE wins five of six direct comparisons and does so by margins of 57.3% to 57.4% in all but one test, the data favors the 1315UE for almost any modern application. The only user who should choose the 10100 is one constrained to the LGA 1200 platform or one specifically targeting Cinebench R15 single-thread performance.

Head-to-Head Benchmarks

The largest win for the Intel Core i3-1315UE comes in Cinebench R23 multi-core, where it scores 6013 against the 10100's 2564. This 57.4% delta is the single biggest gap in the dataset, and it is mirrored exactly in Cinebench R15 multi-core (606 vs 258) and Cinebench R20 multi-core (2525 vs 1076). The consistency of this 57.4% margin across three different Cinebench versions indicates a structural advantage in multi-threaded throughput, likely stemming from the 1315UE's 6 cores and 8 threads compared to the 10100's 4 cores and 8 threads, combined with a 10 MB shared L3 cache versus 6 MB.

In single-core tests, the 1315UE wins Cinebench R20 with 356 versus 152 (57.3% delta) and Cinebench R23 with 849 versus 362 (57.4% delta). The 1315UE's boost clock of 4.50 GHz, higher than the 10100's 4.30 GHz, partially explains this single-core dominance. The lone exception is Cinebench R15 single-core, where the 10100 scores 88 and the 1315UE scores 85, giving the 10100 a 3.5% win. This is a small, isolated result, but it is the only head-to-head test where the older desktop processor prevails.

The average benchmark scores tell a different story. The 10100's average of 1742 and the 1315UE's average of 1739 are statistically tied, with a delta of 0.2% in favor of the 10100. This happens because the 10100 has 14 benchmark results including 3DMark and Geekbench, while the 1315UE has only 6 Cinebench results. The 10100's 3DMark 16-thread score of 3235 and Geekbench multi-core score of 4495 pull its average up, even though it loses every Cinebench multi-core test. The nearest rivals for both CPUs reinforce this balance: the 1315UE's closest competitor is the AMD Ryzen 3 4300U at a -0.2% delta, while the 10100's closest is the same Ryzen 3 4300U at 0% delta, followed by the Intel Core i5-6600 at -0.1% delta and the Intel Core i7-980X at -0.2% delta.
