Architecture Differences

The Intel Core i7-10810U and Intel Core i7-8709G belong to different architectural generations despite sharing the same 14 nm process node from Intel. The 10810U is built on Comet Lake, specifically Comet Lake-U, while the 8709G is based on Kaby Lake, specifically Kaby Lake G. Both use Intel as the foundry and have a 14 nm process, but the core designs differ substantially.

The most significant architectural divergence is in core count and threading. The 10810U provides 6 cores and 12 threads, whereas the 8709G provides 4 cores and 8 threads. This gives the 10810U a 50% advantage in core count and a 50% advantage in thread count, which directly impacts multi-threaded workloads.

Cache hierarchies also differ. Both chips have 64 KB of L1 cache per core and 256 KB of L2 cache per core, but the shared L3 cache is 12 MB on the 10810U versus 8 MB on the 8709G. This 4 MB difference in last-level cache can affect workloads with larger working sets.

Clock behavior is another key architectural difference. The 10810U has a much lower base clock of 1100.00 MHz compared to 3.10 GHz on the 8709G, but the 10810U has a higher boost clock of 4.90 GHz versus 4.10 GHz. The 10810U's lower base clock is paired with a TDP of 25, while the 8709G has a TDP of 65, indicating different thermal and power design targets.

The integrated graphics differ as well. The 10810U includes UHD Graphics, while the 8709G includes Radeon RX Vega M GH. The 8709G's graphics solution is a discrete-class GPU integrated onto the package, which is a notable feature absent from the 10810U.

Memory support is another differentiator. The 10810U supports DDR3 and DDR4 with dual-channel memory, while the 8709G supports DDR4 only, with no memory bus information recorded. Neither chip supports ECC memory.

Sockets are also different: the 10810U uses Intel BGA 1440, while the 8709G uses Intel BGA 2270. Both are mobile segments, and neither has an unlocked multiplier.

The release dates differ, with the 8709G launching in 2018-01-31 and the 10810U launching in 2020-04-01. The 10810U is end-of-life, while the 8709G remains active.

Head-to-Head Benchmarks

The head-to-head benchmark data covers six Cinebench tests, and the Intel Core i7-10810U wins all six. The margin is narrow but consistent across every test.

In Cinebench R15 multi-core, the 10810U scores 686 against the 8709G's 679, a 1% lead. In R15 single-core, the 10810U scores 96 versus 95, a 1.1% advantage. These are small margins, but they favor the 10810U in both multi-threaded and single-threaded rendering.

The R20 tests show a similar pattern. Multi-core scores are 2862 for the 10810U and 2832 for the 8709G, yielding a 1.1% delta. Single-core scores are 404 and 399 respectively, a 1.3% delta, which is the largest margin in any of the six tests.

In R23, the most recent benchmark in the set, the 10810U scores 6816 multi-core versus 6743 for the 8709G, again a 1.1% delta. Single-core R23 scores are 962 and 952, also a 1.1% delta.

The data shows that the 10810U's advantage is consistent across all three Cinebench versions, both in single-core and multi-core workloads. The largest single-core delta is 1.3% in R20, and the largest multi-core delta is 1.1% in R20 and R23. The 10810U wins 6 out of 6 head-to-head tests.

Given the 10810U's higher core count and thread count, one might expect a larger multi-core lead, but the 8709G's higher base clock (3.10 GHz versus 1100.00 MHz) helps it close the gap. The 10810U's boost clock advantage (4.90 GHz versus 4.10 GHz) likely contributes to its single-core wins.

The average benchmark scores in the database show the 10810U at 1971 and the 8709G at 1950, a 21-point difference. Both processors sit at the 44th percentile among all CPUs, indicating similar overall standing in the database.

The Verdict

The benchmark data is clear: the Intel Core i7-10810U wins every single head-to-head test against the Intel Core i7-8709G. Across six Cinebench benchmarks, the 10810U leads by margins ranging from 1% to 1.3%. The 10810U also has a higher average benchmark score (1971 versus 1950) and more cores, threads, and L3 cache.

However, the margins are narrow. A 1.1% difference in multi-core R23 scores is not a transformative gap for most workloads. The 8709G's higher base clock of 3.10 GHz versus 1100.00 MHz on the 10810U helps it remain competitive despite having fewer cores. The 8709G also has a much higher TDP (65 versus 25), which suggests it is designed for a different power envelope.

For users prioritizing multi-threaded performance, the 10810U is the better choice based on its 6-core, 12-thread configuration and consistent benchmark wins. For users who prioritize the integrated graphics capability, the 8709G has the Radeon RX Vega M GH, which is a significant advantage in graphics-heavy tasks, though no graphics benchmarks are recorded in the database.

The production status favors the 8709G, which remains active, while the 10810U is end-of-life. For new system builds, the active status of the 8709G may be relevant. Both chips are at the 44th percentile among all CPUs, indicating they occupy similar performance tiers overall.

Where Each One Wins

Intel Core i7-10810U wins in all recorded CPU benchmarks. The data shows 6 wins out of 6 head-to-head tests. Its advantages are most pronounced in single-core R20 performance, where it leads by 1.3%, and in multi-core R20 and R23, where it leads by 1.1%. The 10810U also has a higher average benchmark score by 21 points.

The 10810U's strengths lie in its core and thread advantage: 6 cores and 12 threads versus 4 cores and 8 threads. Its larger 12 MB L3 cache compared to 8 MB on the 8709G may also benefit workloads with substantial data reuse. Its lower TDP of 25 suggests it is more power-efficient, which is relevant for thin-and-light mobile devices.

Intel Core i7-8709G wins in no recorded CPU benchmarks. However, it has compensating features outside the CPU test suite. The Radeon RX Vega M GH integrated graphics is a substantial upgrade over the UHD Graphics in the 10810U, though no graphics benchmarks are recorded to quantify this. The 8709G's higher base clock of 3.10 GHz means it delivers more consistent performance under sustained loads that do not reach boost frequencies.

The 8709G's active production status is a practical advantage for procurement, as the 10810U is end-of-life. The 8709G also has a higher TDP of 65, which may indicate it is intended for systems with more robust cooling and power delivery, potentially allowing sustained performance closer to its boost clock.

For users who need the best CPU rendering performance, the 10810U is the choice. For users who need a mobile processor with strong integrated graphics and active production status, the 8709G may be preferable, provided the CPU performance deficit is acceptable. The narrow benchmark margins mean the 8709G is not far behind in CPU tasks, making the graphics and availability considerations decisive for many buyers.
