Intel Core i5-14600 vs Intel Core Ultra 9 386H Comparison

Head-to-Head Benchmarks

The benchmark results tell a surprisingly split story. The Intel Core i5-14600 and the Intel Core Ultra 9 386H trade blows across the test suite, with the Ultra 9 taking 10 wins to the i5's 7. But the margins tell a more nuanced tale than the raw win count suggests.

The i5-14600's most dominant performance comes in Cinebench R23 single-core, where it scores 4300 against the Ultra 9's 2071.5, a massive 107.6% advantage. This is the largest delta in the entire head-to-head set. The single-core lead extends to Cinebench R15 as well, with the i5 winning 433 to 303.5, a 42.7% gap. However, in Cinebench R20 single-core, the two are nearly inseparable: the Ultra 9 edges ahead by just 0.2%, scoring 1809 versus 1806.

Multi-core results are equally divided. The i5-14600 wins Cinebench R23 multi-core decisively, scoring 30464 against 20547, a 48.3% lead. Yet in Cinebench R15 multi-core, the Ultra 9 wins with 3223 versus 3070, a 4.7% margin. Cinebench R20 multi-core is almost a tie, with the Ultra 9 ahead by only 0.2% (12820 versus 12794). This inconsistency across Cinebench versions is curious: the Ultra 9 wins in the older R15 and R20 tests, but loses badly in R23.

The Passmark suite reveals where each chip's architecture favors different workloads. The i5-14600 dominates integer math, scoring 117078 versus 87284, a 34.1% lead. It also wins data compression with 434620 versus 352365, a 23.3% margin, and random string sorting at 48043 versus 42135, a 14% gain. The multithread score is close, 35848 versus 35399, a narrow 1.3% win for the i5.

The Ultra 9 386H counters in floating-point math, scoring 108527 against the i5's 85759, a 21% advantage. It also wins extended instructions (29138 versus 25674, an 11.9% lead), data encryption (27150 versus 25082, a 7.6% gain), and physics (3028 versus 2330, a 23.1% margin). The largest Ultra 9 win is in prime number finding, where it scores 341 versus 155, a 54.5% advantage. Single-thread Passmark scores are nearly identical, with the Ultra 9 ahead by just 1.2% (4218 versus 4167).

Where Each One Wins

The i5-14600 is clearly the stronger choice for integer-heavy and memory-bandwidth-sensitive tasks. Its 34.1% lead in integer math and 23.3% lead in data compression suggest strengths in general productivity, database operations, and workloads that process large structured data. The 14% advantage in random string sorting reinforces this pattern: this chip handles sorting and data manipulation tasks efficiently. The 48.3% lead in Cinebench R23 multi-core indicates strong sustained all-core rendering performance, at least in that specific benchmark.

The Ultra 9 386H wins where floating-point precision and specialized instruction sets matter. Its 21% advantage in floating-point math points to scientific computing, 3D rendering, and simulation workloads. The 54.5% lead in prime number finding suggests strong branch prediction and integer division capabilities, which matter in cryptography and number-theoretic algorithms. The 23.1% win in physics and 11.9% win in extended instructions indicate the chip handles SIMD-heavy code well. Data encryption at 7.6% ahead shows its cryptographic throughput is respectable.

For single-threaded responsiveness, the i5-14600's 107.6% lead in Cinebench R23 single-core is the standout metric. However, the almost identical Passmark single-thread scores (4167 versus 4218, just 1.2% apart) complicate the picture. The i5 wins some single-thread tests by huge margins while losing others by tiny amounts, suggesting the two chips have very different single-core performance profiles depending on the instruction mix.

Architecture Differences

The two processors come from entirely different Intel design philosophies. The i5-14600 uses Raptor Lake architecture on a 10 nm process node, built for the Intel Socket 1700 desktop platform. It has 14 cores and 20 threads, indicating a hybrid arrangement of performance and efficiency cores (though the exact core composition is not specified). Its cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache.

The Ultra 9 386H uses the Panther Lake architecture on a 3 nm process node, a significant process shrink. It is a mobile part with 16 cores but only 16 threads, meaning it does not use simultaneous multithreading. Its cache layout differs substantially: 192 KB of L1 per core, 2.5 MB of L2 per core, but only 18 MB of shared L3. The larger per-core L1 and L2 caches suggest a design focused on feeding cores quickly, while the smaller L3 might explain some of the benchmark differences.

The integrated graphics also differ: the i5-14600 has UHD Graphics 770, while the Ultra 9 386H has Intel Xe3 Graphics. Memory support diverges as well: the i5 supports both DDR4 and DDR5, while the Ultra 9 supports DDR5 and LPDDR5X. The Ultra 9 has a listed memory bandwidth of 115.2 GB/s, while the i5's bandwidth figure is not recorded in the database. The i5 supports ECC memory; the Ultra 9 does not.

PCI Express lanes differ: the i5 provides Gen 5 with 16 CPU lanes, while the Ultra 9 provides Gen 5 with 12 CPU lanes. The i5 has a die size of 257 mm², while the Ultra 9's die size is not recorded. Both have locked multipliers, so neither supports manual overclocking.

Specification Differences

The two chips differ across nearly every specification category. The i5-14600 has 14 cores and 20 threads, while the Ultra 9 386H has 16 cores and 16 threads. Base clocks are 2.70 GHz for the i5 and 2.10 GHz for the Ultra 9. Boost clocks are 5.20 GHz and 4.90 GHz respectively. Thermal design power is dramatically different: 65 watts for the i5 versus 25 watts for the Ultra 9, reflecting the desktop versus mobile positioning.

The i5 uses a 10 nm process and Raptor Lake architecture. The Ultra 9 uses a 3 nm process and Panther Lake architecture. The i5 has 80 KB L1 and 2 MB L2 per core, with 24 MB shared L3.

The Verdict

The benchmark data points to a clear division of purpose. The i5-14600 is the choice for users whose workloads depend on high single-thread performance, integer math, and data compression. Its 107.6% lead in Cinebench R23 single-core and 34.1% lead in integer math are decisive advantages. The 23.3% lead in data compression and 14% lead in random string sorting make it the stronger candidate for database work, data processing pipelines, and general desktop productivity. Its 48.3% lead in Cinebench R23 multi-core also suggests strong rendering performance in that test.

The Ultra 9 386H is the pick for floating-point-heavy workloads and mobile deployments. Its 21% lead in floating-point math, 54.5% lead in prime number finding, and 23.1% lead in physics point to scientific and simulation tasks. The 11.9% lead in extended instructions benefits code that leverages SIMD. The 7.6% lead in data encryption is relevant for security-focused workloads. With a 25 watt TDP versus the i5's 65 watts, the Ultra 9 achieves competitive overall performance at a fraction of the power draw, which matters for battery-powered devices.
