Intel Core i9-10900 vs Intel Core i9-10900F Comparison

The Intel Core i9-10900F and Intel Core i9-10900 are nearly identical twins, sharing the same Comet Lake architecture, 10 cores, 20 threads, and clock speeds. The data reveals a fascinating split: the 10900F wins the majority of benchmark head-to-heads, yet the 10900 pulls ahead in specific multi-threaded scenarios. With an average benchmark score of 4664 for the 10900F versus 4614 for the 10900, the delta is a slim 1.1%, indicating that the choice between them hinges on nuanced workload behavior rather than raw architectural superiority.

FAQ

Q: What is the key specification difference between the two processors?

A: The primary difference is the presence of integrated graphics. The Intel Core i9-10900 includes UHD Graphics 630, while the Intel Core i9-10900F has no integrated graphics, which explains the "F" suffix in its name.

Q: How do the two compare in Cinebench R23 multi-core performance?

A: The Intel Core i9-10900F scores 16753 in Cinebench R23 multi-core, while the Intel Core i9-10900 scores 16219. This represents a 3.3% advantage for the 10900F in this rendering workload.

Q: In which benchmark does the Intel Core i9-10900 achieve its largest margin of victory?

A: The Intel Core i9-10900's biggest win is in 3DMark max-threads, where it scores 8083 against the 10900F's 7866, a 2.7% difference. It also wins 3DMark 16-threads and Geekbench multi-core by 1.6% each.

Architecture Differences

Both processors are built on Intel's 14 nm process node and share the Comet Lake architecture and codename. They are both part of the Core 10th Gen series, use the Intel Socket 1200, and have identical cache hierarchies: 64 KB of L1 cache per core, 256 KB of L2 cache per core, and a shared 20 MB L3 cache. Memory support is also identical, with dual-channel DDR4 and a memory bandwidth of 46.9 GB/s, plus PCIe Gen 3 with 16 lanes from the CPU.

The sole architectural divergence is the integrated graphics processor (IGP). The Intel Core i9-10900 ships with UHD Graphics 630, whereas the Intel Core i9-10900F lacks any integrated graphics unit. This difference has no direct impact on CPU compute performance, as both rely on the same 10-core, 20-thread configuration. However, it affects system requirements: the 10900F necessitates a discrete graphics card for display output, while the 10900 can operate with a motherboard's video output. The absence of the IGP on the 10900F does not appear to alter its thermal design power, as both are rated at 65 W TDP, nor does it change the production status, with both marked as end-of-life and released on the same date of 2020-04-29.

Head-to-Head Benchmarks

The head-to-head results paint a clear picture of a processor that dominates in lightly-threaded and rendering tasks, while its sibling counters in certain multi-threaded synthetic loads. The Intel Core i9-10900F secures a commanding lead in the Cinebench suite, winning all six tests. In Cinebench R15 single-core, the 10900F scores 238 against the 10900's 230, a 3.5% advantage. This pattern repeats in Cinebench R20 single-core (993 vs 961, +3.3%) and Cinebench R23 single-core (2365 vs 2289, +3.3%). The multi-core Cinebench results are equally lopsided: R15 shows 1688 vs 1634 (+3.3%), R20 shows 7036 vs 6811 (+3.3%), and R23 shows 16753 vs 16219 (+3.3%). This consistency suggests a small but genuine per-clock efficiency edge for the 10900F in rendering workloads.

Outside of Cinebench, the 10900F also wins 3DMark 2-thread (1608 vs 1598, +0.6%), 3DMark 4-thread (3091 vs 3052, +1.3%), 3DMark 8-thread (5404 vs 5276, +2.4%), and 3DMark single-thread (822 vs 815, +0.9%). Geekbench single-core also favors the 10900F, with a score of 1708 versus 1651, a 3.5% margin. These wins indicate that the 10900F tends to perform better when the load does not saturate all 20 threads.

The Intel Core i9-10900's three victories are concentrated in high-thread-count or multi-core synthetic tests. In 3DMark 16-thread, it scores 7391 against the 10900F's 7274, a 1.6% lead. The margin grows slightly in 3DMark max-threads, where it scores 8083 versus 7866, a 2.7% advantage. Geekbench multi-core shows the 10900 winning 8585 to 8447, also a 1.6% gap. These results suggest that when the workload fully utilizes all cores and threads, the 10900 can pull ahead, possibly due to better sustained power delivery or thermal behavior, though the specific cause is not evident from the data alone.

Specification Differences

The specification tables for the two processors are identical except for two fields. The first is the part number: the Intel Core i9-10900F is designated SRH90, while the Intel Core i9-10900 is SRH8Z. The second and more significant difference is the integrated graphics field. The Intel Core i9-10900 includes UHD Graphics 630, while the Intel Core i9-10900F lists no integrated graphics. All other specifications match exactly: 10 cores, 20 threads, 2.80 GHz base clock, 5.20 GHz boost clock, 65 W TDP, Intel Socket 1200, Comet Lake architecture, 14 nm process, 20 MB shared L3 cache, dual-channel DDR4 memory support, 46.9 GB/s memory bandwidth, PCIe Gen 3 with 16 lanes, and a locked multiplier. The launch MSRP also differs, with the 10900F at $464 and the 10900 at $483, though this is the only price-related detail available.

The Verdict

The benchmark data suggests that the Intel Core i9-10900F is the stronger performer for most users, winning 11 of 14 head-to-head comparisons and achieving a higher average benchmark score. Its consistent 3.3% advantage across all Cinebench tests indicates a subtle but reliable edge in rendering and CPU-intensive tasks. The 10900F also wins all single-threaded tests, making it the better choice for applications that rely on per-core performance. Given that both processors share identical core counts, clocks, and cache, the 10900F's wins are likely due to the absence of the integrated GPU, which may allow slightly better thermal headroom for the CPU cores, though the data does not explicitly confirm this mechanism.

The Intel Core i9-10900, however, is not without merit. Its victories in 3DMark max-threads, 3DMark 16-threads, and Geekbench multi-core show that it can outperform the 10900F when all 20 threads are fully loaded. For users who specifically need a processor with integrated graphics, the 10900 is the only option between the two, as the 10900F requires a discrete GPU. The 10900's 1.6% to 2.7% wins in these specific tests are modest, but they may matter in workloads that scale perfectly with thread count. The data does not support a definitive recommendation for one over the other in all scenarios; it instead reveals a trade-off between raw multi-threaded synthetic scores and everyday single-threaded performance.

Where Each One Wins

The Intel Core i9-10900F is the clear winner in single-threaded and lightly-threaded applications. It takes all single-core benchmarks, including 3DMark single-thread, Cinebench R15/R20/R23 single-core, and Geekbench single-core, with margins ranging from 0.9% to 3.5%. It also excels in rendering workloads, sweeping the entire Cinebench multi-core suite with a uniform 3.3% lead. For users running 3D modeling, video encoding, or any software that uses up to 8 threads, the 10900F's performance is superior. Its wins in 3DMark 2-thread, 4-thread, and 8-thread tests reinforce this pattern, making it the better choice for gaming and general productivity that relies on moderate thread counts.

The Intel Core i9-10900 wins only when the workload saturates all available threads. Its victories in 3DMark 16-thread, 3DMark max-threads, and Geekbench multi-core indicate that it can edge ahead in heavily parallelized tasks like scientific computing, complex simulations, or multi-tasking with many concurrent processes. The 10900 also has the advantage of integrated UHD Graphics 630, which is essential for systems without a discrete GPU. Therefore, the 10900 is the pick for users who prioritize maximum multi-threaded throughput and need built-in display output, while the 10900F is the better performer for everyone else, particularly those who already own a dedicated graphics card and value single-threaded speed.
