Intel Core i7-10700KF vs Intel Core i9-9900KS Comparison

FAQ

Q: Which processor has the higher overall average benchmark score?

A: The Intel Core i9-9900KS records an average benchmark score of 4738, while the Intel Core i7-10700KF sits at 4547. That puts the 9900KS about 4.2% ahead in the aggregate.

Q: Do both CPUs have the same core and thread counts?

A: Yes. Both the i9-9900KS and the i7-10700KF feature 8 cores and 16 threads, so the performance gap comes down to clock behavior, architecture generation, and platform differences rather than core count.

Q: Which chip wins in single-threaded workloads?

A: The i9-9900KS wins every single-thread test in the data, including 3DMark single-thread (841 vs 820), Cinebench R23 single-core (2321 vs 2194), and Geekbench single-core (1715 vs 1637). The margin ranges from 2.6% to 5.8%.

Q: Is the i7-10700KF the newer part?

A: Yes. The i7-10700KF launched on 2020-04-29, while the i9-9900KS launched on 2019-10-27. The 9900KS is marked as End-of-life in the database, whereas the 10700KF is Active.

Q: Do both CPUs support the same socket?

A: No. The i9-9900KS uses Intel Socket 1151, and the i7-10700KF uses Intel Socket 1200. They are not drop-in interchangeable.

Q: Does either chip have integrated graphics?

A: The i9-9900KS includes UHD 630 integrated graphics, while the i7-10700KF has no integrated graphics, as indicated by the null value in the database. The "F" suffix on the 10700KF reflects that absence.

Architecture Differences

Both processors are built on Intel's 14 nm process, but they represent different architecture generations. The i9-9900KS is Coffee Lake, specifically the Coffee Lake-R refresh, while the i7-10700KF is Comet Lake. Both have 8 cores and 16 threads, with identical per-core cache layouts: 64 KB of L1 per core, 256 KB of L2 per core, and 16 MB of shared L3 cache. The die size for the 9900KS is recorded at 180 mm², while the 10700KF has no die size listed in the database.

The more meaningful architectural difference is the platform. The 9900KS is built for Intel Socket 1151, and the 10700KF for Intel Socket 1200. Both use PCIe Gen 3 with 16 lanes from the CPU, both support dual-channel DDR4, and neither supports ECC memory. The 9900KS includes UHD 630 integrated graphics, a feature absent from the 10700KF. The 10700KF is part of the Core 10th Gen series, while the 9900KS is part of the Core i9 (Coffee Lake Refresh) generation.

Clock behavior also differs. The 9900KS has a base clock of 4.00 GHz and a boost clock of 5.00 GHz. The 10700KF has a lower base clock of 3.80 GHz but a slightly higher boost clock of 5.10 GHz. Despite the lower base clock, the 10700KF's boost advantage does not translate into benchmark wins. The 9900KS also has a TDP of 127, versus 125 for the 10700KF. Both have unlocked multipliers, so overclocking is possible on either platform.

Memory bandwidth is one area where the newer part has a spec-side edge. The 10700KF is rated at 46.9 GB/s, compared to 42.7 GB/s for the 9900KS. That advantage, however, does not appear in the benchmark results, where the 9900KS consistently leads.

Head-to-Head Benchmarks

The head-to-head data is unambiguous: the i9-9900KS wins all 14 recorded benchmark comparisons. The margins, however, vary by workload type. The smallest wins come in the 3DMark thread scaling tests. At 16 threads, the 9900KS scores 7376 against 7268 for the 10700KF, a 1.5% lead. At max threads, the gap is 7360 vs 7247, or 1.6%. The 8-thread test shows a 3.5% margin (5787 vs 5589), and the 4-thread test also shows 3.5% (3276 vs 3164). The 2-thread test comes in at 3.4% (1670 vs 1615), and the single-thread test at 2.6% (841 vs 820).

The Cinebench suite shows larger, more consistent margins. In Cinebench R15, the 9900KS leads by 5.8% in multi-core (1657 vs 1566) and by 5.4% in single-core (233 vs 221). Cinebench R20 shows 5.8% in both multi-core (6907 vs 6528) and single-core (974 vs 921). Cinebench R23 repeats that pattern with a 5.8% margin in both multi-core (16446 vs 15543) and single-core (2321 vs 2194). These consistent 5.8% deltas suggest the 9900KS has a steady clock or efficiency advantage in rendering-style workloads.

Geekbench results sit in between. The 9900KS leads multi-core by 4.6% (9771 vs 9338) and single-core by 4.8% (1715 vs 1637). Across all 14 tests, the 9900KS never trails, and the average benchmark score difference (4738 vs 4547) reflects that dominance. The 10700KF's higher boost clock of 5.10 GHz does not appear to deliver any recorded win, likely because the 9900KS's higher base clock and older but well-tuned architecture sustain performance more effectively in these workloads.

Specification Differences

The two CPUs differ in several recorded fields. The socket is different: Intel Socket 1151 for the 9900KS, Intel Socket 1200 for the 10700KF. Base clocks differ, with the 9900KS at 4.00 GHz and the 10700KF at 3.80 GHz. Boost clocks differ in the opposite direction: 5.00 GHz for the 9900KS, 5.10 GHz for the 10700KF. TDP is close but not identical: 127 for the 9900KS, 125 for the 10700KF.

Memory bandwidth favors the 10700KF at 46.9 GB/s versus 42.7 GB/s for the 9900KS. Integrated graphics are present on the 9900KS (UHD 630) and absent on the 10700KF. The die size is listed for the 9900KS at 180 mm², with no entry for the 10700KF. The 9900KS has a launch MSRP of $513, while the 10700KF has no listed launch MSRP.

The architectures differ as well: Coffee Lake-R for the 9900KS, Comet Lake for the 10700KF. Production status also splits them: the 9900KS is End-of-life, the 10700KF is Active. The part numbers are SRG1Q for the 9900KS and SRH74 for the 10700KF. Both have unlocked multipliers, 8 cores, 16 threads, 16 MB of shared L3 cache, dual-channel DDR4 support, PCIe Gen 3 with 16 lanes, and no ECC support.

The Verdict

The data points to a clear performance hierarchy. The i9-9900KS wins every benchmark in the head-to-head comparison, with margins from 1.5% to 5.8%. Its average benchmark score of 4738 places it 4.2% ahead of the 10700KF's 4547. In the database's percentile ranking, the 9900KS sits at the 59th percentile of all CPUs, while the 10700KF sits at the 58th. That is a narrow gap in the broader market, but within this direct comparison, the 9900KS is the faster chip in every measured workload.

The 10700KF does have platform advantages that matter for a new build. It is on Socket 1200, it is still Active in production, and it offers higher rated memory bandwidth (46.9 GB/s vs 42.7 GB/s). Its higher boost clock of 5.10 GHz gives it a nominal clock advantage, but the recorded benchmarks show no workload where that translates into a win. The 9900KS, despite being the older part and marked End-of-life, delivers better results across 3DMark, Cinebench, and Geekbench.

For someone choosing between these two specifically, the 9900KS is the stronger performer in the database's measurements, but it requires a Socket 1151 platform. The 10700KF is the more current, actively produced option on Socket 1200 with a higher memory bandwidth rating, yet it trails in every recorded benchmark. The 10700KF also lacks integrated graphics, which may matter if a discrete GPU is not always present.

Where Each One Wins

The i9-9900KS wins in every benchmark category recorded. Its largest margins appear in Cinebench tests, where it leads by 5.8% in R20 multi-core, R23 multi-core, R23 single-core, and R15 multi-core. That makes it the stronger choice for rendering, content creation, and any workload that scales with sustained multi-threaded performance. It also wins the single-thread tests, including Geekbench single-core (4.8% ahead) and Cinebench R23 single-core (5.8% ahead), so it holds the edge in lightly threaded tasks as well.

The 10700KF does not win any of the 14 recorded benchmarks, but it does have characteristics that suit a different build scenario. Its higher memory bandwidth rating (46.9 GB/s) is a spec-level advantage, even if it does not produce a benchmark win. It is the Active production part on the newer Socket 1200 platform, which matters for system longevity and availability. Its slightly higher boost clock of 5.10 GHz offers overclocking headroom potential, though the stock results do not overtake the 9900KS.

In practical terms, the 9900KS is the pick for raw performance in the workloads the database measures, especially Cinebench-style rendering and Geekbench general computing. The 10700KF is the pick for a builder who prioritizes a current platform, active production status, and higher memory bandwidth, and who is willing to trade a few percentage points of measured performance for those platform benefits.
