Architecture Differences

The architectural split between these two processors is significant. The i7-10510U uses the Comet Lake architecture, specifically Comet Lake-U, built on Intel’s 14 nm process. The i7-1065G7 uses the Ice Lake architecture, specifically Ice Lake-U with Sunny Cove cores, on a 10 nm process. This process difference is fundamental: the 10 nm node allows for denser transistors and more efficient power delivery, which manifests in the benchmark results.

Cache layouts differ as well. The i7-10510U has 64 KB of L1 cache per core, while the i7-1065G7 has 80 KB per core. Both have 256 KB of L2 cache per core and 8 MB of shared L3 cache. The larger L1 cache in the Ice Lake part likely contributes to its superior single-thread performance, as more data can be stored closer to the execution cores.

The sockets are different: the i7-10510U uses Intel BGA 1440, while the i7-1065G7 uses Intel BGA 1526. This means they are not interchangeable in motherboards. The i7-1065G7 also has a recorded die size of 123 mm², whereas the i7-10510U has no die size recorded in the database.

Memory support differs substantially. The i7-10510U supports both DDR3 and DDR4, while the i7-1065G7 supports only DDR4. The Ice Lake part has a dual-channel memory bus with a bandwidth of 51.2 GB/s, while the Comet Lake chip has no memory bus or bandwidth figures recorded. The i7-1065G7 also lists PCIe Gen 3 support, while the i7-10510U has no PCIe data.

Thermal design power (TDP) is another key architectural difference. The i7-10510U has a TDP of 25 watts, while the i7-1065G7 has a TDP of 15 watts. This lower TDP for the Ice Lake part is notable because it achieves higher performance while consuming less power, as the benchmark scores show. The i7-1065G7 is listed as Active production status, while the i7-10510U is End-of-life.

Head-to-Head Benchmarks

Production status is End-of-life for the i7-10510U and Active for the i7-1065G7. The i7-1065G7 has a part number of SRG0N, while the i7-10510U has none recorded. Neither processor has an unlocked multiplier.

Where Each One Wins

The i7-1065G7 wins in almost every workload category. Rendering tasks, represented by Cinebench R15, R20, and R23, show consistent 21%+ leads in both single-core and multi-core tests. This suggests the Ice Lake architecture’s newer core design delivers better instructions per clock, despite the lower boost clock.

Encryption workloads are the standout win for the i7-1065G7. The PassMark data encryption score of 4552 versus 2151 represents a 52.7% advantage, likely due to hardware acceleration features in the Sunny Cove cores. This makes the Ice Lake part notably better for security-related tasks like disk encryption or VPN processing.

Math-heavy workloads also favor the i7-1065G7. Integer math shows an 18.2% lead, floating point math a 15.2% lead, and finding prime numbers a 24.1% edge. Extended instruction set performance is 12.9% better. These results indicate the i7-1065G7 handles computational tasks more efficiently.

The i7-10510U has exactly one recorded win: random string sorting, where it scores 11068 versus 10688, a 3.6% edge. This minor victory in a narrow test does not compensate for the broad losses elsewhere. The i7-10510U also has a higher boost clock of 4.90 GHz versus 3.90 GHz, which might help in short, lightly threaded bursts, but the benchmark data does not show a corresponding advantage.

For users prioritizing power efficiency, the i7-1065G7’s 15 watt TDP versus 25 watts for the i7-10510U is notable. The Ice Lake chip delivers higher performance while drawing less power, which is critical for thin-and-light laptops where battery life matters.

The Verdict

The data is unambiguous: the Intel Core i7-1065G7 is the superior processor in nearly every measurable way. It wins 16 of 17 head-to-head benchmarks, with the only loss being a 3.6% margin in random string sorting. The Cinebench tests show a consistent 21% advantage across all versions, indicating that the Ice Lake architecture provides a substantial generational improvement over Comet Lake.

The i7-1065G7 achieves this dominance despite a lower base clock (1300.00 MHz versus 1800.00 MHz) and lower boost clock (3.90 GHz versus 4.90 GHz). This suggests the Ice Lake core design is significantly more efficient per clock cycle. The 10 nm process node and larger L1 cache (80 KB versus 64 KB per core) likely contribute to this efficiency.

For users who need maximum performance in rendering, encryption, math, or general multithreaded work, the i7-1065G7 is the clear choice. Its 15 watt TDP also makes it better suited for fanless or ultraportable designs. The i7-10510U retains a small niche in random string sorting, but this is a narrow workload unlikely to matter for most users.

The percentile rankings are close (65th for the i7-10510U versus 64th for the i7-1065G7), but the average benchmark score tells a different story. The i7-10510U has an average score of 8580, while the i7-1065G7 has 8293, yet the individual head-to-head results show the Ice Lake part winning decisively. This discrepancy likely stems from the different benchmark sets recorded for each CPU.

Given the overwhelming benchmark evidence, the i7-1065G7 should be the preferred choice for any workload that benefits from higher compute throughput. The i7-10510U is an older design with a higher TDP and fewer wins, making it a weaker option for modern mobile computing. The database clearly shows that Ice Lake outperforms Comet Lake in this direct comparison.
