Intel Core Ultra 5 225F vs Intel Core Ultra 9 285 Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive performance gap between the Intel Core Ultra 5 225F and the Intel Core Ultra 9 285. Across all 17 recorded head-to-head tests, the Core Ultra 9 285 wins every single matchup. The most dramatic difference appears in Cinebench R23 multicore, where the Ultra 9 scores 48,945 versus the Ultra 5's 16,467, a delta of -66.4% for the smaller chip. That means the Ultra 9 delivers roughly three times the multicore rendering throughput.

Single-core results also favor the Ultra 9, though by a smaller margin. In Cinebench R23 single-core, the Ultra 9 posts 6,909 against 1,893 for the Ultra 5, a -72.6% delta. The PassMark single-thread test shows a much narrower gap: 4,881 versus 4,397, a -9.9% difference. This suggests that while the Ultra 9 has a clear clock-speed advantage in burst workloads, the per-core architecture is not dramatically faster when limited to a single thread.

The Cinebench R15 and R20 runs follow the same pattern. In R15 multicore, the Ultra 9 scores 4,933 versus 2,660, a -46.1% delta. In R20 multicore, the Ultra 9 hits 20,556 versus 11,059, a -46.2% delta. Single-core in R15 shows 696 versus 287, a -58.8% delta, while R20 single-core shows 2,901 versus 1,561, also -46.2%. The consistency across Cinebench versions indicates that the multicore advantage scales with core count, while the single-core advantage is more modest.

PassMark integer math shows the Ultra 9 at 164,869 versus 66,417 for the Ultra 5, a -59.7% delta. Floating-point math is similarly lopsided: 194,988 versus 92,554, a -52.5% delta. Data compression results show 602,121 versus 310,843, a -48.4% delta. Encryption workloads favor the Ultra 9 at 46,949 versus 22,648, a -51.8% delta. Extended instruction sets show 45,357 versus 28,027, a -38.2% delta, which is one of the smaller gaps.

The PassMark multithread score for the Ultra 9 is 56,602 versus 31,004 for the Ultra 5, a -45.2% delta. Physics simulation scores are 3,598 versus 2,430, a -32.5% delta. Random string sorting shows 73,651 versus 37,325, a -49.3% delta. Prime number finding has the smallest absolute difference: 459 versus 352, a -23.3% delta.

The overall average benchmark score reflects this imbalance. The Ultra 5 sits at 37,313, while the Ultra 9 reaches 75,488. That is roughly double the average score, aligning with the multicore-heavy workloads that dominate the benchmark suite. The percentile rankings also differ: the Ultra 5 sits at the 85th percentile of all CPUs, while the Ultra 9 reaches the 95th percentile.

The Verdict

The data is unambiguous: the Intel Core Ultra 9 285 is the faster processor in every recorded test. For any workload that benefits from additional cores, threads, or higher clock speeds, the Ultra 9 is the correct choice. The Cinebench R23 multicore result alone, 48,945 versus 16,467, shows a 66.4% advantage. That margin is large enough to matter for video rendering, 3D simulation, and other heavily threaded tasks.

The Ultra 5 225F does not win a single benchmark in the head-to-head table. Its only competitive area is single-thread performance, where the PassMark single-thread gap is just 9.9%. However, even there the Ultra 9 leads. For users whose workloads are strictly single-threaded and light, the Ultra 5 could suffice, but the data does not support a claim that it outperforms the Ultra 9 anywhere.

The Ultra 9 also holds advantages in memory and platform features. It supports ECC memory, while the Ultra 5 does not. It includes integrated graphics with Arc Xe-LPG Graphics 64EU, while the Ultra 5 has no integrated graphics. These features add to its utility in workstation and server-adjacent environments.

From a performance-per-dollar perspective, the database does not include pricing analysis, but the launch MSRP values are recorded. The Ultra 5 has a launch MSRP of $231, while the Ultra 9 has a launch MSRP of $579. That price difference is substantial, but the performance difference is also substantial, especially in multicore tasks.

Where Each One Wins

The Intel Core Ultra 9 285 wins every benchmark category in the recorded data. Its largest margins come from multicore workloads: Cinebench R23 multicore (-66.4% delta), Cinebench R23 single-core (-72.6% delta), and PassMark integer math (-59.7%). These results indicate that the Ultra 9 is best suited for rendering, compilation, scientific computing, and any parallel workload.

The Ultra 9 also leads in memory-sensitive tasks. Data compression shows a 48.4% advantage, and random string sorting shows a 49.3% advantage. These tasks benefit from the larger 36 MB shared L3 cache versus the 20 MB on the Ultra 5. The Ultra 9 also has 24 cores and 24 threads, compared to 10 cores and 10 threads on the Ultra 5, which directly explains the multicore gaps.

The Intel Core Ultra 5 225F does not win any benchmark, but its closest relative performance appears in single-thread tests. The PassMark single-thread gap is only 9.9%, and the PassMark physics gap is 32.5%. These are the smallest deltas in the entire table. The Ultra 5 may be acceptable for light desktop use, office productivity, or legacy single-threaded applications, but the data does not show it beating the Ultra 9 in any scenario.

The Ultra 5 does offer a lower launch MSRP of $231, and it shares the same Arrow Lake architecture, 3 nm process node, TSMC foundry, 17,800 million transistors, and 243 mm² die size as the Ultra 9. It also has the same dual-channel DDR5 memory support and memory bandwidth of 102.4 GB/s. For users who do not need the extra cores or ECC support, the Ultra 5 provides a lower-cost entry into the same platform.

Architecture Differences

Both processors belong to the Intel Core Ultra Series 2 and use the Arrow Lake architecture with the Arrow Lake-S codename. They share the same 3 nm process node, TSMC foundry, 17,800 million transistors, and 243 mm² die size. Both use the Intel Socket 1851 and support PCIe Gen 5 with 20 lanes from the CPU.

The core configuration is the primary architectural difference. The Ultra 5 225F has 10 cores and 10 threads, while the Ultra 9 285 has 24 cores and 24 threads. Neither processor supports simultaneous multithreading, so threads equal cores in both cases. The base clock is higher on the Ultra 5 at 3.30 GHz, but the boost clock is higher on the Ultra 9 at 5.60 GHz versus 4.90 GHz.

Cache hierarchies differ in the shared L3 portion. Both have 192 KB of L1 cache per core and 3 MB of L2 cache per core. The Ultra 5 has 20 MB of shared L3 cache, while the Ultra 9 has 36 MB. This larger cache likely contributes to the Ultra 9's advantages in compression and sorting workloads.

The memory controller is identical in both: dual-channel DDR5 with 102.4 GB/s bandwidth. The Ultra 9 adds ECC memory support, which the Ultra 5 lacks. The integrated graphics situation also differs. The Ultra 9 includes Arc Xe-LPG Graphics 64EU, while the Ultra 5 has no integrated graphics. This makes the Ultra 5 dependent on a discrete GPU for display output.

Both are active production parts, but their release dates differ. The Ultra 9 launched on 2024-12-31, while the Ultra 5 launched on 2025-01-06. Both are locked multipliers, meaning overclocking is not supported. The part numbers are SRQD4 for the Ultra 9 and SRQD2SRVF9 for the Ultra 5.

The percentile rankings confirm the performance hierarchy. The Ultra 9 sits at the 95th percentile of all CPUs, while the Ultra 5 sits at the 85th percentile. The nearest rivals for the Ultra 9 include AMD EPYC 8224P, AMD EPYC 4545P, AMD Ryzen 7 PRO 9755X3D, and AMD Ryzen 7 PRO 9755, all within roughly 0.3% of its average score. The Ultra 5's nearest rivals include Intel Core i9-13900HK, AMD Ryzen 7 7735H, Intel Core i7-13700, and AMD Ryzen 7 160, all within about 0.5% of its average score.
