Intel Core i7-11370H vs Intel Core i7-6800K Comparison

The Intel Core i7-11370H and the Intel Core i7-6800K are separated by nearly five years of silicon evolution, but their average benchmark scores land them within 0.8% of each other. The 11370H averages 2861 points across its tested workloads, while the 6800K averages 2838 points. This places both CPUs at the 51st percentile among all processors, with the 11370H sitting 0.1% behind the AMD Ryzen 3 PRO 5475U and 0.7% ahead of the Intel Xeon E-2126G. The 6800K, meanwhile, matches the Intel Core i5-10600 at 0% delta and trails the Xeon E-2126G by 0.1%. The headline is that a 28-watt mobile chip and a 140-watt desktop chip with two fewer cores and four fewer threads produce nearly identical aggregate performance, but the individual benchmark breakdown reveals starkly different strengths.

Head-to-Head Benchmarks

The 11370H dominates the Cinebench suite across the board. In Cinebench R15 multi-core, it scores 987 against the 6800K’s 916, a 7.8% advantage. The single-core R15 test shows the same 7.8% delta, with scores of 139 and 129. Moving to Cinebench R20, the 11370H posts 4113 multi-core and 580 single-core, versus 3819 and 538 for the 6800K — again a 7.7% and 7.8% lead respectively. Cinebench R23 continues the pattern: 9793 versus 9093 in multi-core (7.7% delta) and 1382 versus 1283 in single-core (7.7% delta). These are consistent margins, indicating that the 11370H’s Tiger Lake architecture delivers a uniform performance uplift across rendering workloads that scale from one thread to many.

The single biggest win for the 11370H comes in Geekbench single-core, where it scores 1667 against the 6800K’s 1237. That is a 34.8% advantage — the largest delta in the entire comparison. This is the clearest signal of the generational leap in per-core throughput. The 11370H’s 4.80 GHz boost clock, paired with the newer 10 nm process, allows it to crush the 6800K’s 3.60 GHz boost clock in lightly threaded tasks.

However, the 6800K strikes back in Geekbench multi-core. It scores 5688 versus the 11370H’s 5485, a 3.6% lead. This is the only benchmark where the 6800K wins, and it does so because its six cores and twelve threads outnumber the 11370H’s four cores and eight threads. The 6800K’s 15 MB of shared L3 cache, versus 12 MB on the 11370H, also helps in memory-heavy multi-threaded scenarios. Despite losing every Cinebench test, the 6800K’s extra two physical cores give it enough raw parallel throughput to edge out the mobile chip in Geekbench’s mixed workload.

The overall win count is 7-1 in favor of the 11370H, but the magnitude of the 6800K’s Geekbench multi-core win is modest compared to the 11370H’s 34.8% single-core blowout. The Cinebench results are surprisingly one-sided given the core count disparity — the 11370H’s higher clocks and newer architecture overcome its two-core deficit even in multi-threaded rendering. The 6800K’s lone victory suggests that Geekbench’s multi-core test includes memory latency or bandwidth components that favor the 6800K’s quad-channel memory bus.

Where Each One Wins

The 11370H is the clear winner for any workload that prioritizes single-threaded responsiveness or lightly threaded performance. Its 34.8% lead in Geekbench single-core makes it the better choice for everyday desktop tasks, web browsing, office productivity, and any application that relies on one or two fast cores. The consistent 7.7-7.8% advantage across all Cinebench versions also means it handles rendering jobs — even multi-core ones — more efficiently than its core count would suggest. The 11370H’s integrated Iris XE 96EU graphics provide a fallback display output, though the data does not include iGPU benchmarks, so no performance claims can be made there.

The 6800K wins in Geekbench multi-core by 3.6%, which points to workloads that scale well beyond eight threads and benefit from its six physical cores. Applications that saturate all twelve threads — such as video encoding, 3D scene compilation, or software builds — will see a modest edge on the 6800K. Its quad-channel memory bus (76.8 GB/s versus 51.2 GB/s on the 11370H) gives it a bandwidth advantage that can matter in memory-bound multi-threaded tasks. The 6800K also has an unlocked multiplier, allowing overclocking, though no overclocked benchmark scores are included in the data.

The 11370H’s 7.7% Cinebench R23 multi-core win over a chip with 50% more cores is the most telling result. It indicates that the 11370H’s per-core efficiency is so high that it overcomes the core deficit in rendering workloads. For users who run a mix of single-threaded and multi-threaded applications, the 11370H is the more versatile performer. The 6800K only makes sense for users who specifically need maximum multi-threaded throughput in Geekbench-style workloads and who can tolerate its higher power draw and end-of-life status.

The Verdict

The data points decisively toward the Intel Core i7-11370H for most buyers. It wins 7 of 8 head-to-head benchmarks, including every Cinebench test and Geekbench single-core by a massive 34.8%. Its average benchmark score of 2861 is 0.8% higher than the 6800K’s 2838, and it achieves this with a 28 W TDP versus the 6800K’s 140 W TDP. The 11370H is also currently in active production, while the 6800K is end-of-life. For anyone building a new system or upgrading from an older platform, the 11370H offers superior performance in virtually every measured category.

The only scenario where the 6800K is the better pick is if your workload is dominated by the specific multi-threaded pattern captured in Geekbench multi-core, where it leads by 3.6%. That advantage comes from its six cores and twelve threads, plus quad-channel memory. If your applications scale perfectly across twelve threads and are memory-bandwidth sensitive, the 6800K holds a narrow edge. However, that edge is small, and it comes with a much higher power draw, an older 14 nm process, and no integrated graphics. The 11370H’s 7.7% lead in Cinebench R23 multi-core suggests that even for heavily threaded rendering, the newer chip is faster. The 6800K is only defensible for users who already own a compatible Socket 2011-3 motherboard and want to maximize multi-threaded performance without a platform change.
