Where Each One Wins

The Intel Core i5-13600KF is the clear victor in traditional multi-core productivity and legacy single-threaded benchmarks. It wins 14 of the 19 head-to-head comparisons, including decisive victories in Cinebench R23 multi-core (31,727 vs 20,781.5, a 34.5% lead) and Cinebench R23 single-core (4,479 vs 2,129.5, a 52.5% lead). It also dominates in integer math, scoring 122,169 versus 85,922 (a 29.7% lead), and in data compression, scoring 475,505 versus 335,859 (a 29.4% lead). This pattern extends across Geekbench, where the Core i5-13600KF leads by 17.8% in multi-core and 12.4% in single-core, and across PassMark multi-thread tests, where it holds an 8.8% edge. For users running standard rendering, compilation, or general-purpose desktop workloads, the Core i5-13600KF is the stronger performer.

The Intel Core Ultra 9 285H wins in a narrower but distinct set of workloads that point to specific architectural strengths. Its most dramatic victory is in PassMark find prime numbers, where it scores 330 versus 152, a 117.1% improvement. It also wins PassMark floating-point math by 20.8% (109,190 vs 90,424) and PassMark physics by 12.9% (2,513 vs 2,226). Notably, the Ultra 9 285H also wins PassMark single-threaded tests by 7.2% (4,415 vs 4,118), despite losing Cinebench single-core tests by a wide margin. This suggests the Ultra 9 285H excels in specific instruction patterns and floating-point-heavy calculations, making it a strong choice for scientific computing, physics simulation, and certain encryption or number-theoretic tasks.

Architecture Differences

The two processors are built on entirely different architectures and process nodes. The Ultra 9 285H uses Arrow Lake-H, manufactured on a 3 nm process by TSMC, while the Core i5-13600KF uses Raptor Lake-S, manufactured on a 10 nm process by Intel. This process gap is substantial, with the 3 nm node offering significant density and efficiency advantages, though the data shows the 10 nm part still wins on raw performance in most tests. The Ultra 9 285H is a mobile part on an Intel BGA 2049 socket, while the Core i5-13600KF is a desktop part on an Intel Socket 1700.

Cache hierarchies also differ notably. The Ultra 9 285H has 192 KB of L1 cache per core and 3 MB of L2 cache per core, compared to 80 KB of L1 and 2 MB of L2 per core on the Core i5-13600KF. Both share 24 MB of L3 cache. The larger per-core caches on the Ultra 9 285H likely contribute to its wins in prime number finding and floating-point math, where working sets may fit more efficiently in the faster cache levels. The Core i5-13600KF compensates with a larger die size of 257 mm² and a higher 125 W TDP, versus 45 W for the Ultra 9 285H, allowing it to sustain higher clocks under load.

The Ultra 9 285H integrates Arc Graphics 140T, while the Core i5-13600KF has no integrated graphics. Memory support also diverges: the Ultra 9 285H supports DDR5 and LPDDR5X with a stated memory bandwidth of 102.4 GB/s, while the Core i5-13600KF supports DDR4 and DDR5 but has no listed memory bandwidth figure. PCIe connectivity favors the desktop part, with 16 Gen 5 lanes versus 8 Gen 5 lanes on the Ultra 9 285H.

Specification Differences

The two CPUs differ across nearly every core specification. The Ultra 9 285H has 16 cores and 16 threads, while the Core i5-13600KF has 14 cores and 20 threads. Base clocks are 2.90 GHz for the Ultra 9 285H and 3.50 GHz for the Core i5-13600KF, while boost clocks are 5.40 GHz and 5.10 GHz respectively. The TDP rating is a major differentiator: 45 W for the mobile part versus 125 W for the desktop part, reflecting their intended thermal envelopes.

Process node and foundry differ, with the Ultra 9 285H on TSMC's 3 nm process and the Core i5-13600KF on Intel's 10 nm process. The die size is only listed for the Core i5-13600KF at 257 mm². Cache per core is larger on the Ultra 9 285H (192 KB L1 and 3 MB L2) versus the Core i5-13600KF (80 KB L1 and 2 MB L2), though both share 24 MB of L3. The Ultra 9 285H supports DDR5 and LPDDR5X memory with 102.4 GB/s bandwidth, while the Core i5-13600KF supports DDR4 and DDR5 with no bandwidth figure listed. PCIe lane counts differ: 8 Gen 5 lanes for the Ultra 9 285H versus 16 Gen 5 lanes for the Core i5-13600KF. The Ultra 9 285H includes integrated Arc Graphics 140T, while the Core i5-13600KF has none. The Core i5-13600KF has an unlocked multiplier, while the Ultra 9 285H does not. Release dates are January 2025 for the Ultra 9 285H and September 2022 for the Core i5-13600KF.

Head-to-Head Benchmarks

The biggest win for the Core i5-13600KF comes in Cinebench R23 single-core, where it scores 4,479 against 2,129.5, a 52.5% advantage. This is a massive gap, far larger than the 12.4% lead seen in Geekbench single-core (2,487 vs 2,178). The discrepancy between these two single-threaded tests highlights how workload-specific performance can be; the Cinebench scene rendering relies on instruction patterns that heavily favor the Raptor Lake core design. In Cinebench R23 multi-core, the Core i5-13600KF leads by 34.5% (31,727 vs 20,781.5), and in Cinebench R20 multi-core by 8.4% (13,325 vs 12,201). The data compression test shows a 29.4% lead for the Core i5-13600KF (475,505 vs 335,859), and integer math shows a 29.7% lead (122,169 vs 85,922).

The Ultra 9 285H’s largest win is in PassMark find prime numbers, where it scores 330 versus 152, a 117.1% improvement. This is the single most lopsided result in either direction. It also wins floating-point math by 20.8% (109,190 vs 90,424) and physics by 12.9% (2,513 vs 2,226). In PassMark single-thread, the Ultra 9 285H wins by 7.2% (4,415 vs 4,118), a notable reversal from the Cinebench single-core result. The data encryption test is nearly tied, with the Core i5-13600KF winning by just 3% (26,957 vs 26,140).

Overall, the head-to-head record is 14 wins for the Core i5-13600KF and 5 for the Ultra 9 285H. However, the average benchmark scores are nearly identical, meaning the Core i5-13600KF’s wins are often in tests with larger score ranges, while the Ultra 9 285H’s wins are concentrated in fewer but more dramatic outliers. The Core i5-13600KF’s wins in Cinebench and Geekbench are broad-based, covering both multi-core and single-core, while the Ultra 9 285H’s wins are specialized, pointing to distinct microarchitectural strengths in floating-point and branch-heavy workloads.
