Intel Core i3-10105F vs Intel Core i7-10750H Comparison

The Intel Core i7-10750H and Intel Core i3-10105F are both 10th Generation Comet Lake parts, but they target very different segments: one is a mobile processor, the other a desktop chip. Their benchmark profiles reflect this split, with the i7-10750H dominating multi-threaded workloads while the i3-10105F ekes out narrow single-thread wins. The data shows a clear overall victor in raw performance, but the story is more nuanced than a simple score comparison.

Head-to-Head Benchmarks

The most striking pattern in the head-to-head data is the consistency of the i7-10750H’s victory margin. Across the Cinebench suite, the mobile chip wins by nearly the same percentage in every test. In Cinebench R15 multi-core, the i7 scores 979 against the i3’s 759, a 29% advantage. The single-core R15 test shows the same 29% delta, with scores of 138 and 107. This uniformity carries into R20, where the multi-core gap is 28.9% (4081 vs 3165) and the single-core gap is 29.1% (576 vs 446). R23 repeats the pattern almost exactly: a 28.9% lead in multi-core (9718 vs 7537) and another 28.9% in single-core (1372 vs 1064). This suggests the performance difference is structural—tied to core count and clock architecture—rather than workload-specific.

Geekbench provides a slight deviation from the Cinebench trend. In multi-core, the i7-10750H leads with 5574 points against 4920, a 13.3% margin that is notably smaller than the ~29% seen in Cinebench. More importantly, the i3-10105F wins the Geekbench single-core test outright, scoring 1470 versus the i7’s 1417, a 3.6% advantage for the desktop part. This is the first hint that the i3’s higher base clock of 3.70 GHz, compared to 2.60 GHz on the i7, gives it an edge in lightly-threaded, latency-sensitive tasks.

The Passmark suite amplifies the i7-10750H’s multi-threaded dominance. In integer math, the i7 scores 39730 versus 28921 for the i3, a 37.4% lead. Floating-point math shows a similar 38% gap (25070 vs 18166). The largest single delta in the entire comparison appears in the find-prime-numbers test, where the i7 scores 39 against the i3’s 25—a 56% advantage. Data compression favors the i7 by 28% (167213 vs 130647), and encryption by 29.1% (3930 vs 3045). Extended instructions run 19.6% faster on the i7 (10470 vs 8753), while random string sorting is 30.5% ahead (21416 vs 16414). The Passmark multithread score gives the i7 a 30.1% edge (11616 vs 8930), and physics testing shows a 22.6% lead (700 vs 571).

The only other wins for the i3-10105F come in the Passmark single-thread tests, where it scores 2647 against the i7’s 2625, a marginal 0.8% advantage. This mirrors the Geekbench single-core result, reinforcing that the i3’s higher clocks help it in single-threaded scenarios, but only slightly. Out of 19 head-to-head benchmarks, the i7-10750H wins 16, while the i3-10105F takes 3.

The Verdict

The data makes the choice straightforward for most users. The Intel Core i7-10750H is the faster processor in nearly every measurable way, particularly in multi-threaded workloads where its 6 cores and 12 threads overwhelm the i3-10105F’s 4 cores and 8 threads. Its 56% lead in prime-number finding and 38% lead in floating-point math indicate that compute-heavy applications will run substantially better on the i7. The 28-30% margins across Cinebench R15, R20, and R23 further cement its position for rendering and content creation tasks.

However, the i3-10105F has a narrow but consistent edge in single-threaded performance, winning Geekbench single-core by 3.6% and Passmark single-thread by 0.8%. For applications that rely on a single core and are sensitive to clock speed, the i3 could feel marginally snappier. Yet these wins are small, and the i7-10750H’s boost clock of 5.00 GHz is actually higher than the i3’s 4.40 GHz, meaning the i7 can reach higher peak frequencies when thermal headroom allows.

The i7-10750H also carries a 68th percentile ranking versus the i3’s 67th, and its average benchmark score of 13024 exceeds the i3’s 12644. The nearest rivals confirm the i7’s positioning: it sits within 0.1% of the Intel Core i5-9400F and 0.3% of the Core Ultra 3 105UL, while the i3 is closest to the Intel Atom x7809C and Core i3-1215U. For a user choosing purely on performance data, the i7-10750H is the clear pick. The i3-10105F only makes sense if single-threaded responsiveness is the absolute priority and the small 0.8-3.6% edge justifies accepting 28-38% losses in multi-threaded tasks.

Architecture Differences

Both processors share the same Comet Lake architecture and are built on Intel’s 14 nm process node, but their implementations diverge significantly. The i7-10750H uses the Comet Lake-H codename and is a mobile part with a 45 W TDP, while the i3-10105F uses the Comet Lake-R codename and is a desktop part with a 65 W TDP. This difference in thermal envelope and market segment explains much of their performance disparity.

The core configuration is the primary architectural split. The i7-10750H offers 6 cores and 12 threads, while the i3-10105F is limited to 4 cores and 8 threads. This extra parallelism directly drives the i7’s multi-threaded wins. Cache sizes also differ: the i7 has 12 MB of shared L3 cache, whereas the i3 has only 6 MB. Both share the same 64 KB L1 and 256 KB L2 per core, but the doubled L3 on the i7 gives it more room to hold working sets in multi-threaded scenarios.

Clock speeds present a contrasting picture. The i3-10105F has a higher base clock of 3.70 GHz versus 2.60 GHz on the i7, which explains the i3’s single-thread wins. However, the i7’s boost clock of 5.00 GHz exceeds the i3’s 4.40 GHz, meaning the i7 can ramp higher under load. The i7’s lower base clock is likely a concession to its 45 W mobile TDP, while the i3’s 65 W desktop budget allows a higher sustained base frequency.

Memory bandwidth also differs, with the i7 supporting 46.9 GB/s versus 42.7 GB/s on the i3. Both use dual-channel DDR4, but the i7’s higher bandwidth figure gives it a small edge in memory-intensive workloads. The integrated graphics further separate the two: the i7-10750H includes UHD Graphics, while the i3-10105F has no integrated graphics at all, requiring a discrete GPU. Both processors support PCIe Gen 3 with 16 lanes (CPU only), and neither has an unlocked multiplier.

Where Each One Wins

The Intel Core i7-10750H wins in every scenario that leverages multiple cores or heavy computational loads. Its 6-core/12-thread configuration delivers decisive victories in integer math (37.4% ahead), floating-point math (38% ahead), and prime-number finding (56% ahead). Content creation workloads, represented by Cinebench R15, R20, and R23, all favor the i7 by approximately 29%. Data compression and encryption tasks run 28% and 29.1% faster respectively on the i7, making it the better choice for archiving, database work, and secure data handling. The Passmark multithread score of 11616 versus 8930 further confirms its superiority in parallel processing. Its higher memory bandwidth of 46.9 GB/s versus 42.7 GB/s also supports bandwidth-sensitive applications.

The Intel Core i3-10105F wins in a narrow but real niche: single-threaded responsiveness. Its Geekbench single-core score of 1470 beats the i7’s 1417, and its Passmark single-thread score of 2647 edges out 2625. These wins, while small, are consistent across two different test suites. For applications that cannot utilize more than one or two threads, such as certain legacy software or lightly-threaded games, the i3’s higher base clock may translate to slightly faster response times. The i3 also holds a 67th percentile ranking versus the i7’s 68th, indicating they are closely matched in the broader CPU landscape, but the i3’s wins are confined to this single-thread domain.
