Intel Core i7-9700KF vs Intel Core i9-10980HK Comparison

FAQ

Q: Which processor has the higher boost clock?

A: The Intel Core i9-10980HK reaches a boost clock of 5.30 GHz, while the Intel Core i7-9700KF tops out at 4.90 GHz. The i9 holds a 0.40 GHz advantage in single-thread boost potential.

Q: How do the two chips compare in thread count?

A: The i7-9700KF has 8 cores and 8 threads, meaning no hyper-threading. The i9-10980HK also has 8 cores but 16 threads, effectively doubling the logical processing capacity in multi-threaded workloads.

Q: Which processor has a larger L3 cache?

A: The i9-10980HK features 16 MB of shared L3 cache, compared to 12 MB on the i7-9700KF. That is a 4 MB difference in favor of the mobile chip.

Q: Are both processors unlocked for overclocking?

A: Yes, both the i7-9700KF and the i9-10980HK have an unlocked multiplier. This allows manual clock adjustment on compatible platforms.

Q: What is the power envelope difference?

A: The i7-9700KF is rated at 95 W TDP, while the i9-10980HK is rated at 45 W TDP. The desktop chip draws more power by design, though the mobile chip operates in a lower thermal budget.

Q: Which processor has integrated graphics?

A: The i9-10980HK includes UHD Graphics, while the i7-9700KF has no integrated graphics. The "KF" suffix indicates the lack of an iGPU.

The Verdict

The benchmark record is unambiguous: the Intel Core i9-10980HK wins all six recorded head-to-head comparisons. The i9 leads by a consistent margin of 5.5% to 5.6% across every Cinebench test, whether single-core or multi-core. The data shows a clean sweep, with the i9 taking every recorded win.

For users prioritizing raw multi-threaded throughput, the i9-10980HK is the clear choice. Its 16 threads deliver higher scores in Cinebench R15, R20, and R23 multi-core runs, and the single-core results also favor the i9. The i7-9700KF, despite its higher base clock and desktop-oriented power budget, cannot match the i9 in any recorded benchmark.

The i7-9700KF still holds relevance for those who need a desktop platform with an unlocked multiplier and end-of-life availability. It also offers a lower launch MSRP of $374 compared to the i9's $643, though pricing should not be the deciding factor in pure performance terms. The i9-10980HK is the better performer in every measured metric, making it the stronger pick for compute-heavy tasks.

For single-threaded applications, the i9's 5.30 GHz boost clock and higher Cinebench single-core scores give it a narrow but consistent edge. The i7-9700KF's 4.90 GHz boost is competitive, but the recorded deltas show a 5.5% gap in favor of the i9 across all single-core tests.

Head-to-Head Benchmarks

The head-to-head results are remarkably consistent. In Cinebench R15 multi-core, the i9-10980HK scores 1291 against the i7-9700KF's 1219, a 5.6% advantage. The single-core R15 test shows 182 versus 172, a 5.5% delta. These margins repeat almost exactly in newer Cinebench versions.

Cinebench R20 multi-core: the i9 scores 5381, the i7 scores 5082, a 5.6% gap. Single-core R20: 759 versus 717, again 5.5%. The pattern holds in Cinebench R23 as well. Multi-core R23 sees the i9 at 12812 and the i7 at 12100, a 5.6% lead. Single-core R23: 1808 versus 1708, a 5.5% margin.

What stands out is the uniformity of the delta. Whether the workload is heavily threaded or purely single-core, the i9-10980HK maintains a near-identical advantage. This suggests the performance gap is not workload-specific but stems from architectural and clock differences that apply broadly.

The i7-9700KF's best showing is in multi-core R23, where it scores 12100. That is 712 points behind the i9's 12812. In single-core R15, the i7 scores 172, only 10 points behind the i9's 182. The absolute differences are small in single-core tests, but the percentage gap remains constant.

No recorded benchmark shows the i7 winning. The i9-10980HK wins all six head-to-head tests, with deltas ranging from 5.5% to 5.6%. This is a decisive sweep, not a marginal one. The data indicates that the i9 is faster across the board, with no workload category where the i7 can close the gap.

Specification Differences

The two processors differ in several key specification fields. The i7-9700KF has a base clock of 3.60 GHz, while the i9-10980HK runs at 2.40 GHz. The i7 starts higher, but the i9 boosts higher at 5.30 GHz compared to 4.90 GHz.

TDP is another major split. The i7-9700KF is rated at 95 W, the i9-10980HK at 45 W. This reflects their market segments: desktop versus mobile. The socket types also differ: the i7 uses Intel Socket 1151, the i9 uses Intel BGA 1440. The i7 is a desktop part, the i9 is a mobile part.

Memory bus information is not fully recorded for both. The i7-9700KF lists dual-channel memory and a memory bandwidth of 42.7 GB/s. The i9-10980HK does not have recorded memory bus or bandwidth data. Both support DDR4 memory, and neither supports ECC.

Integrated graphics separate the two. The i7-9700KF has none, while the i9-10980HK includes UHD Graphics. The i7's "KF" designation means no iGPU, which is a clear specification difference.

Release dates differ by over a year. The i7-9700KF launched on 2019-01-07, the i9-10980HK on 2020-04-01. Both are marked as end-of-life. The i7 has a launch MSRP of $374, the i9 has a launch MSRP of $643.

Die size is recorded only for the i7-9700KF at 180.3 mm². The i9-10980HK has no recorded die size. Both use a 14 nm process node from Intel. The i7's part number is SRG16SRFAC, the i9's is SRH8T.

Architecture Differences

Both processors are built on Intel's 14 nm process node, but they come from different architecture families. The i7-9700KF uses Coffee Lake, specifically from the Coffee Lake Refresh generation. The i9-10980HK uses Comet Lake, specifically Comet Lake-H. Both are 14 nm parts, but Comet Lake is a newer iteration of Intel's 14 nm process.

Core and thread counts differ despite matching core numbers. Both have 8 physical cores, but the i7-9700KF has 8 threads, while the i9-10980HK has 16 threads. The i9 enables hyper-threading, the i7 does not. This is the most significant architectural difference for multi-threaded workloads.

Cache hierarchy is similar in per-core structure but different in total. Both have 64 KB of L1 per core and 256 KB of L2 per core. The L3 cache differs: 12 MB shared on the i7, 16 MB shared on the i9. That extra 4 MB of L3 gives the i9 more capacity for shared data.

PCIe capabilities are identical in the recorded data: Gen 3, 16 lanes from the CPU for both. This means expansion and GPU connectivity are theoretically equivalent, though the socket and platform differ.

The integrated graphics situation is a notable architectural difference. The i9-10980HK includes UHD Graphics, which is part of the Comet Lake-H die. The i7-9700KF has no integrated graphics, which is a deliberate design choice for the desktop "KF" variant. This affects system flexibility for users who want a fallback display output without a discrete GPU.

Both chips are unlocked for overclocking, and both are end-of-life. The i9's higher boost clock of 5.30 GHz, combined with hyper-threading and more L3 cache, explains its consistent benchmark advantage. The i7's higher base clock of 3.60 GHz does not compensate in the recorded tests. The architectural differences point clearly to the i9-10980HK as the more capable processor in both single-thread and multi-thread workloads.
