Intel Core i5-1035G7 vs Intel Core i7-10810U Comparison

Head-to-Head Benchmarks

The recorded data presents a remarkably consistent picture across all six Cinebench workloads: the Intel Core i7-10810U wins every single head-to-head comparison, yet by margins so narrow that they border on statistical noise. In Cinebench R15 multicore, the i7-10810U scores 686 against the i5-1035G7's 678, a 1.2% advantage. The single-core R15 test shows 96 versus 95, a 1.1% edge. Moving to Cinebench R20, the multicore result is 2862 versus 2829 (1.2% delta), and single-core is 404 versus 399 (1.3% delta). The newest workload, Cinebench R23, repeats the pattern: 6816 against 6736 in multicore (1.2%), and 962 against 951 in single-core (1.2%).

The consistency of these deltas is notable. Every test lands between 1.1% and 1.3%, suggesting a systematic, architecture-level advantage rather than a workload-specific quirk. The i7-10810U does not suddenly surge in one test or fall behind in another; it simply edges ahead everywhere. For practical purposes, these differences are tiny. A 1.2% multicore advantage in Cinebench R23 translates to roughly 80 points, which most users would never perceive in real-world rendering tasks. However, the data does establish a clear, if narrow, hierarchy.

What makes this interesting is that the i7-10810U achieves these wins despite having a lower base clock (1100 MHz versus 1200 MHz) and a higher TDP (25 W versus 15 W). The i7's boost clock of 4.90 GHz versus 3.70 GHz likely explains part of the single-core edge, but the multicore advantage must come from its additional cores. The i7 has 6 cores and 12 threads, while the i5 has 4 cores and 8 threads. Yet the multicore delta is only 1.2%, which raises a question: why does a 50% core advantage produce such a small performance gap? The answer likely lies in thermal and power constraints, which the benchmark database records indirectly through the TDP figures.

Architecture Differences

The two processors come from different architectural generations within Intel's 10th Gen family. The i7-10810U uses Comet Lake, built on Intel's 14 nm process, while the i5-1035G7 uses Ice Lake, built on the newer 10 nm process. This node difference is reflected in the die size: the i5-1035G7 has a measured die of 123 mm², while the i7-10810U's die size is not recorded. The 10 nm process allows Ice Lake to pack more transistors per area, but the Comet Lake part compensates with a larger core count.

Cache configurations differ significantly. The i7-10810U has 64 KB of L1 per core, 256 KB of L2 per core, and 12 MB of shared L3. The i5-1035G7 has 80 KB of L1 per core, 256 KB of L2 per core, and only 6 MB of shared L3. The i7 has twice the L3 cache, which helps with data-heavy workloads, but the i5's larger per-core L1 suggests a different memory hierarchy design. The i5 also records a memory bandwidth of 51.2 GB/s, while the i7's memory bandwidth is not listed in the database.

Memory support also diverges. The i7-10810U supports both DDR3 and DDR4, while the i5-1035G7 supports only DDR4. Both use dual-channel memory buses. The i7 uses a BGA 1440 socket, whereas the i5 uses BGA 1526, meaning they are not interchangeable in motherboards. Both support PCIe Gen 3, and neither supports ECC memory. The integrated graphics differ as well: UHD Graphics on the i7 versus Iris Plus on the i5, with the database not recording specific graphics benchmark scores.

The i5-1035G7 has a part number (SRGKJ) recorded, while the i7-10810U does not. The i7 carries a higher TDP of 25 W versus 15 W for the i5, which is a crucial architectural trade-off. The i7 also has a lower base clock (1100 MHz versus 1200 MHz) but a much higher boost clock (4.90 GHz versus 3.70 GHz). This suggests the i7 is designed to burst to high frequencies for short periods, while the i5 maintains a more modest, efficient pace.

Where Each One Wins

The i7-10810U wins all six recorded benchmarks, so the data does not show a single workload where the i5-1035G7 comes out ahead. However, the margins are so small that the practical winner depends on context beyond raw scores. For single-threaded tasks, the i7's 1.1% to 1.3% edge in Cinebench R15, R20, and R23 single-core tests is minimal. The i7's higher boost clock (4.90 GHz) likely drives this advantage, but the i5's higher base clock (1200 MHz) means it may sustain performance better under prolonged load before boosting.

For multicore workloads, the i7's advantage is similarly narrow. The 1.2% delta in all three Cinebench multicore tests suggests that the i7's extra two cores and four threads are not being fully utilized, possibly due to thermal throttling at 25 W TDP. The i5, despite having fewer cores, stays close because its 10 nm process may allow more efficient power delivery. In a sustained rendering task, the i5 might actually match or exceed the i7 if the i7 cannot maintain boost clocks.

The i5-1035G7's advantages lie outside the recorded benchmark scores. It has a smaller die (123 mm²), which typically correlates with lower production costs and potentially better thermals per watt. Its 15 W TDP makes it more suitable for fanless or ultra-thin designs. The Iris Plus integrated graphics are generally considered a step up from UHD Graphics, though no graphics benchmarks are in the database. The i5 also has a higher memory bandwidth figure (51.2 GB/s), which could benefit certain compute tasks.

For users prioritizing raw Cinebench scores, the i7 is the clear choice, winning every test. For users prioritizing efficiency, the i5's lower TDP and newer process node are compelling. The data cannot quantify the i5's efficiency advantage directly, but the 10 nm node and 15 W TDP strongly suggest it.

The Verdict

Based strictly on the recorded benchmark data, the Intel Core i7-10810U is the faster processor in every measured workload. Its six wins out of six head-to-head comparisons, with deltas ranging from 1.1% to 1.3%, make it the unambiguous choice for users who prioritize Cinebench performance. The i7's higher boost clock (4.90 GHz) and larger L3 cache (12 MB versus 6 MB) likely contribute to its consistent edge.

However, the data also shows that the i5-1035G7 is remarkably close. A 1.2% multicore delta is negligible in real-world terms. The i5's 15 W TDP, 10 nm process, and 123 mm² die size suggest it achieves near-parity with significantly less power. For thin-and-light laptops where thermals and battery life matter more than a few Cinebench points, the i5-1035G7 may be the smarter choice, even though the raw scores favor the i7.

The i7-10810U is end-of-life, while the i5-1035G7 remains active in production. This status difference affects availability and long-term support. The i7 also has a higher TDP (25 W versus 15 W), which means it needs better cooling and will draw more power under load. The i5's integrated Iris Plus graphics and recorded 51.2 GB/s memory bandwidth add to its appeal for multimedia tasks.

Buyers should choose the i7-10810U if they want the fastest possible Cinebench scores and can accommodate a 25 W TDP. Buyers should choose the i5-1035G7 if they prefer an active, efficient part with a newer process node and lower power draw.
