Where Each One Wins

The benchmark results show a clear division of labor. The Intel Core Ultra 9 185H dominates in Geekbench multi-core, scoring 11657 against the i5's 10171, a 14.6% victory. It also wins the Cinebench R15 multi-core test with 2801.5 versus 2442, an impressive 14.7% margin. In the PassMark suite, the Ultra 9 takes the majority of tests, including floating point math (73270 vs 69442, +5.5%), random string sorting (39598 vs 36219, +9.3%), and multithread (29376 vs 28508, +3%). This pattern indicates the Ultra 9 is generally superior in mixed workload and memory-intensive tasks.

The Intel Core i5-14500HX, however, is the clear winner in Cinebench R23 tests. It scores 24234 in multi-core versus the Ultra 9's 17984.5 (-25.8%) and 3421 in single-core versus 1810.5 (-47.1%). It also wins Cinebench R15 single-core with 344 against 264.5 (-23.1%). The i5 takes the PassMark find prime numbers test as well, scoring 130 against 123 (-5.4%), and Geekbench single-core with 2129 versus 1794 (-15.7%). These wins suggest the i5 has a significant advantage in pure CPU compute tasks that rely heavily on single-thread speed and specific instruction efficiency.

Architecture Differences

The two processors are built on different Intel architectures and process nodes. The Ultra 9 185H uses the Meteor Lake architecture, which is the basis for the Core Ultra Series 1, fabricated on a 7 nm process by Intel. The i5-14500HX uses the Raptor Lake architecture, specifically the Raptor Lake-HX refresh, built on a 10 nm process. This node difference is notable, as the 7 nm process on the Ultra 9 is a more advanced manufacturing technology than the 10 nm on the i5.

Cache layouts also differ. The Ultra 9 has 112 KB of L1 cache per core and 2 MB of L2 per core, while the i5 has 80 KB of L1 per core and 2 MB of L2 per core. Both share 24 MB of L3 cache. The i5 has a die size of 257 mm², while the Ultra 9's die size is not listed. The i5 also supports ECC memory, which the Ultra 9 does not. The i5 has a multiplier unlocked, indicating overclocking capability, while the Ultra 9 is locked. PCIe support differs as well, with the Ultra 9 offering Gen 5 with 8 lanes (CPU only) and the i5 offering Gen 5 with 16 lanes (CPU only).

Specification Differences

The core and thread counts differ, with the Ultra 9 having 16 cores and 22 threads versus the i5's 14 cores and 20 threads. Base clocks are significantly different: the Ultra 9 runs at 3.90 GHz, while the i5 runs at 2.60 GHz. Boost clocks are closer, at 5.10 GHz for the Ultra 9 and 4.90 GHz for the i5. TDP ratings differ, with the i5 at 55 watts and the Ultra 9 at 45 watts. The sockets are not the same: the Ultra 9 uses Intel BGA 2049, while the i5 uses Intel BGA 1964.

Memory support shows a key difference. The Ultra 9 supports DDR5 with a memory bandwidth of 89.6 GB/s, while the i5 supports both DDR4 and DDR5 but has no listed memory bandwidth figure. Both have dual-channel memory buses. The integrated graphics differ as noted, with the Ultra 9 using Arc Xe-LPG Graphics 128EU and the i5 using UHD Graphics 770. The release dates are also distinct: the Ultra 9 launched on December 13, 2023, while the i5 launched on January 7, 2024. The Ultra 9 has a launch MSRP of $640, while the i5 has no listed launch MSRP. Part numbers are SRN23 for the Ultra 9 and SRMXJ for the i5.

Head-to-Head Benchmarks

The Cinebench R23 multi-core test shows the i5-14500HX's biggest win, scoring 24234 against the Ultra 9's 17984.5, a -25.8% delta. This is a substantial margin that suggests the i5's higher TDP of 55 watts may contribute to sustained multi-core performance. In Cinebench R23 single-core, the i5 again dominates with 3421 versus 1810.5, a -47.1% delta, which is the largest gap in the entire dataset. The Cinebench R15 single-core test follows a similar pattern, with the i5 winning 344 to 264.5 (-23.1%).

Conversely, the Ultra 9 185H wins the Cinebench R15 multi-core test with 2801.5 against 2442, a 14.7% advantage. In Geekbench multi-core, the Ultra 9 scores 11657 versus 10171, a 14.6% win. The Geekbench single-core test goes to the i5, however, with 2129 against 1794 (-15.7%). The PassMark tests are mostly Ultra 9 victories, including random string sorting (39598 vs 36219, +9.3%), floating point math (73270 vs 69442, +5.5%), and multithread (29376 vs 28508, +3%). The i5 only wins PassMark find prime numbers (130 vs 123, -5.4%). The remaining PassMark tests, such as data compression (339489 vs 333851, +1.7%) and integer math (98302 vs 95584, +2.8%), are narrow Ultra 9 wins.

The Verdict

The data presents a nuanced picture. The Intel Core Ultra 9 185H is the more consistent performer in everyday and mixed workloads, winning 14 of 19 tests. Its advantages in Geekbench multi-core (14.6%) and Cinebench R15 multi-core (14.7%) suggest it handles multi-threaded applications well, while its PassMark wins in floating point and random string sorting indicate strong memory and math throughput. Users prioritizing a balanced mobile processor with a lower TDP of 45 watts and a newer 7 nm process should lean toward the Ultra 9.

The Intel Core i5-14500HX, despite losing the majority of tests, is the definitive winner in Cinebench R23 benchmarks. Its single-core score of 3421 is nearly double the Ultra 9's 1810.5, and its multi-core score of 24234 is 25.8% higher. This indicates the i5 is built for raw compute performance, particularly in rendering or simulation tasks that scale with core speed and high TDP (55 watts). For users running intensive single-threaded or specific multi-core workloads where Cinebench performance is a proxy for real-world results, the i5-14500HX is the clear choice. In summary, the Ultra 9 185H is the all-around mobile workhorse, while the i5-14500HX is a specialized compute-focused part with exceptional peak performance in specific benchmarks.
