Head-to-Head Benchmarks

The benchmark results tell a story of two very different performance profiles. The i5-9400F wins decisively in Cinebench, a suite that heavily stresses all cores simultaneously. Its R23 multi-core score of 8040 is 335 points higher than the i5-9500’s 7705, a 4.2% margin. This pattern repeats across the entire Cinebench family: R15 multi-core (810 vs 776, -4.2%), R15 single-core (114 vs 109, -4.4%), R20 multi-core (3376 vs 3236, -4.1%), R20 single-core (476 vs 456, -4.2%), and R23 single-core (1135 vs 1087, -4.2%). The i5-9400F also wins PassMark physics (653 vs 619, +5.2%) and find prime numbers (38 vs 36, +5.3%).

The i5-9500 fires back across a broader range of tests. Its single-core superiority is most visible in Geekbench single-core: 1448 versus 1344, a 7.7% advantage—the largest margin in any test. Geekbench multi-core also favors the i5-9500 (5402 vs 5106, +5.8%). The i5-9500 wins all PassMark computational suites except physics and prime numbers. The most notable victories include floating-point math (23788 vs 22465, +5.9%), integer math (27574 vs 26155, +5.4%), data encryption (3125 vs 2902, +7.7%), and single-thread (2565 vs 2428, +5.6%). It also wins multithread (9826 vs 9455, +3.9%), data compression (136283 vs 132877, +2.6%), extended instructions (12088 vs 11684, +3.5%), and random string sorting (16894 vs 16298, +3.7%).

The win count favors the i5-9500: 11 wins versus 8 for the i5-9400F. However, the i5-9400F’s Cinebench sweep is consistent and large in rendering-specific workloads, suggesting its lower base clock (2.90 GHz vs 3.00 GHz) does not hinder sustained all-core rendering tasks. Meanwhile, the i5-9500’s higher boost clock (4.30 GHz vs 4.10 GHz) appears to drive its single-thread and general compute wins.

The Verdict

The data points to a clear recommendation for most users: the Intel Core i5-9500 is the better all-around processor. It wins more benchmarks (11 vs 8), has a higher average score (13452 vs 13041), and offers integrated UHD 630 graphics—eliminating the need for a discrete GPU. Its advantages in Geekbench single-core (+7.7%), data encryption (+7.7%), floating-point math (+5.9%), and integer math (+5.4%) make it the superior choice for everyday computing, productivity, and mixed workloads.

The Intel Core i5-9400F is the specialist’s pick. If your workload is dominated by Cinebench-style rendering or physics simulations, the i5-9400F consistently outperforms the i5-9500 by about 4-5% across all six Cinebench tests and PassMark physics. It also wins find prime numbers by 5.3%. For a system that already has a discrete GPU and is used primarily for 3D rendering, the i5-9400F’s rendering advantage is real and measurable.

However, the i5-9500’s integrated graphics provide a fundamental flexibility that the i5-9400F cannot match. The i5-9400F requires a separate graphics card for any display output, adding system cost and complexity. The i5-9500 can function as a complete platform on its own. Given that both CPUs have the same core count, cache, memory support, and TDP, and the i5-9500 wins the majority of benchmarks, the i5-9500 is the default recommendation. The i5-9400F is only preferable for users with a dedicated GPU and rendering-specific workloads where its Cinebench and physics advantages translate directly to faster output.
