The Verdict

The benchmark data splits cleanly along workload type. The Intel Core Ultra 5 245K is the dominant part across the majority of measured tests, winning 15 out of 17 head-to-head matchups. Its advantages in multi-core rendering, math workloads, and data processing are substantial, often exceeding 50%. Its average benchmark score of 54053 and 91st percentile ranking put it clearly above the 336H, which averages 34485 and ranks at the 84th percentile. The 245K is the appropriate selection for desktop users who need maximum throughput in CPU-intensive tasks such as video rendering, scientific computing, or multithreaded application builds.

The Intel Core Ultra 5 336H holds a genuine edge in specific single-core scenarios. Its Cinebench R23 single-core score of 3387 is 37.1% higher than the 245K's 2132, and its Cinebench R15 single-core score of 341 beats 322 by 5.6%. However, the 336H loses the Cinebench R20 single-core test, scoring 1422 against 2169, a 52.5% deficit. The 336H also loses the PassMark single-thread tests, 4013 versus 4714, a 17.5% difference. The data shows a mobile processor aimed at efficiency, with a 25 W TDP versus 125 W for the desktop part, and a lower boost clock of 4.60 GHz against 5.20 GHz. The 336H is the choice only for those prioritizing peak performance in Cinebench R23 and R15 single-core workloads, or for systems that require the lower thermal envelope and mobile form factor.

Head-to-Head Benchmarks

The largest single margin in the dataset belongs to the Intel Core Ultra 5 245K in PassMark data compression, where it scores 458817 against 280340, a 63.7% advantage. The 245K also posts a 60.2% lead in random string sorting, scoring 55098 versus 34402. Integer math favors the 245K by 58.7%, with a score of 98524 against 62070, and floating point math favors it by 58.6%, 130678 versus 82415. Data encryption shows a 56.3% edge for the 245K, 33286 versus 21291, and extended instructions show a 53.3% edge, 37617 versus 24542.

The Cinebench suite tells a more mixed story. In multi-core R15, the 245K scores 3850 versus 2418, a 59.2% lead. In multi-core R20, the 245K scores 15368 versus 10076, a 52.5% lead. In multi-core R23, the gap narrows considerably: the 245K scores 25066 against 23991, just 4.5% ahead. Single-core results flip direction. The 245K wins R20 single-core by 52.5%, scoring 2169 against 1422, but loses R23 single-core by 37.1%, scoring 2132 against 3387, and loses R15 single-core by 5.6%, scoring 322 against 341.

The PassMark multithread test gives the 245K a 50.8% win, 43047 versus 28545. The physics test is closer, with the 245K ahead 3081 versus 2682, a 14.9% margin. The single-thread PassMark test shows a 17.5% win for the 245K, 4714 versus 4013. Across all recorded tests, the 245K's average benchmark score of 54053 exceeds the 336H's 34485 by roughly 56.7%, a figure consistent with its 91st percentile ranking versus the 336H's 84th percentile.

Specification Differences

The two processors differ in nearly every core specification. The Intel Core Ultra 5 245K uses 14 cores and 14 threads, while the Intel Core Ultra 5 336H uses 16 cores and 16 threads. Base clocks diverge sharply: the 245K runs at 4.20 GHz, the 336H at 1.90 GHz. Boost clocks also differ, with the 245K reaching 5.20 GHz and the 336H reaching 4.60 GHz. Thermal design power reflects their different market segments: the 245K is rated at 125 W, the 336H at 25 W.

The 245K uses the Intel Socket 1851, while the 336H uses Intel BGA 2540, a soldered mobile package. The 245K has an unlocked multiplier; the 336H does not. The 245K carries the part number SRQCT and launched with a release date of 2024-10-23. The 336H carries the part number SA4RD and launched on 2026-01-04. The 245K has a launch MSRP of $319; the database records no launch MSRP for the 336H.

Memory support differs as well. The 245K supports DDR5 only, while the 336H supports DDR5 and LPDDR5X. Both use dual-channel memory buses, but the 336H records a higher memory bandwidth of 115.2 GB/s versus 102.4 GB/s for the 245K. The 245K supports ECC memory; the 336H does not. PCIe lane counts also differ: the 245K provides Gen 5 with 20 lanes (CPU only), while the 336H provides Gen 5 with 12 lanes (CPU only). Integrated graphics differ, with the 245K using Arc Xe-LPG Graphics 64EU and the 336H using Intel Xe3 Graphics.

Architecture Differences

The Intel Core Ultra 5 245K belongs to the Core Ultra Series 2, built on the Arrow Lake architecture with the codename Arrow Lake-S. It is the Ultra 5 generation of that desktop platform. The Intel Core Ultra 5 336H belongs to the Core Ultra Series 3, built on the Panther Lake architecture with the codename Panther Lake, and represents the Ultra 5 (Panther Lake-H) mobile generation.

Both processors are fabricated on a 3 nm process node, but the foundries differ. The 245K is manufactured by TSMC, while the 336H is manufactured by Intel. The 245K records 17,800 million transistors and a die size of 243 mm². The database records no transistor count or die size for the 336H.

Cache organization differs between the two. Both share 192 KB of L1 per core, but L2 cache is 3 MB per core on the 245K and 2.5 MB per core on the 336H. Shared L3 cache is 24 MB on the 245K and 18 MB on the 336H. The mobile part uses a smaller L2 and L3 allocation, consistent with its lower power target.

The 245K targets the desktop market segment with active production status and an unlocked multiplier for overclocking. The 336H targets the mobile market segment, also active, but with a locked multiplier and a BGA socket that precludes user replacement. The 336H's higher memory bandwidth of 115.2 GB/s, despite its lower power envelope, suggests the Panther Lake architecture prioritizes memory throughput for the mobile platform. The 245K's ECC support and larger PCIe lane count align with desktop workstation use cases.

Where Each One Wins

The Intel Core Ultra 5 245K wins every PassMark test recorded in the head-to-head dataset. Data compression, encryption, extended instructions, prime number finding, floating point math, integer math, multithread, physics, random string sorting, and both single-thread tests all favor the desktop part. Its margins range from 14.9% in physics to 63.7% in data compression. The 245K also wins all three Cinebench multi-core tests and the Cinebench R20 single-core test. This makes it the clear choice for tasks that stress sustained multi-core throughput, math-heavy computation, and data manipulation workloads.

The Intel Core Ultra 5 336H wins two single-core Cinebench tests: R15 single-core with 341 versus 322, a 5.6% edge, and R23 single-core with 3387 versus 2132, a 37.1% edge. These wins do not extend to the PassMark single-thread tests, where the 245K leads by 17.5%, nor to Cinebench R20 single-core, where the 245K leads by 52.5%. The 336H's wins are therefore isolated to specific rendering benchmarks rather than a general single-core advantage. The 336H also offers LPDDR5X memory support and a higher memory bandwidth figure, which may benefit integrated memory controllers in mobile designs, but the recorded benchmark data does not show a corresponding performance edge outside those two tests.

The 245K's 91st percentile ranking versus the 336H's 84th percentile, combined with its 15-to-2 head-to-head win count, leaves little ambiguity in the overall comparison. The 336H is competitive only in narrow single-core rendering scenarios, while the 245K dominates the broader benchmark profile.
