Intel Core i3-14100F vs Intel Core Ultra 5 336H Comparison

The Verdict

The benchmark data presents a decisive outcome: the Intel Core Ultra 5 336H wins every recorded head-to-head test against the Intel Core i3-14100F, with 17 wins out of 17 comparisons. The Ultra 5 336H posts a 46% higher average benchmark score (34485 versus 18519) and sits in the 84th percentile of all CPUs, while the i3-14100F ranks at the 72nd percentile. The largest gap appears in prime number finding, where the Ultra 5 336H leads by 79.6%, while the narrowest margin is in single-threaded PassMark performance, a 5.9% advantage.

The i3-14100F does retain one structural advantage: it is a desktop part on Intel Socket 1700 with a launch MSRP of $109, uses DDR4 and DDR5 memory support, and carries ECC memory support. The Ultra 5 336H is a mobile processor on Intel BGA 2540 with no ECC support, but its 16 cores, larger caches, 3 nm process node, and integrated Intel Xe3 Graphics make it the stronger compute package in every measured workload. For desktop builders anchored to the LGA1700 platform, the i3-14100F remains a functional option, but the data shows no scenario where the Ultra 5 336H does not deliver higher performance.

Architecture Differences

The two processors come from entirely different Intel families. The i3-14100F is part of Core 14th Gen, built on Raptor Lake architecture (Raptor Lake-R codename) using a 10 nm process node with a die size of 163 mm². The Ultra 5 336H belongs to Core Ultra Series 3, using Panther Lake architecture on a 3 nm process node. The process node difference is substantial: 10 nm versus 3 nm, which helps explain the Ultra 5 336H's ability to pack 16 cores into a 25 W TDP envelope.

Core counts diverge sharply. The i3-14100F has 4 cores and 8 threads, while the Ultra 5 336H has 16 cores and 16 threads. The i3-14100F relies on Hyper-Threading to reach 8 threads from 4 physical cores; the Ultra 5 336H does not use simultaneous multithreading, so its 16 threads come from 16 physical cores. Cache hierarchies also differ: the i3-14100F uses 80 KB L1 per core and 1.25 MB L2 per core with 12 MB shared L3, while the Ultra 5 336H uses 192 KB L1 per core and 2.5 MB L2 per core with 18 MB shared L3.

Clock speeds favor the desktop chip on paper. The i3-14100F runs a 3.50 GHz base clock and 4.70 GHz boost clock, versus 1.90 GHz base and 4.60 GHz boost for the Ultra 5 336H. Despite the lower clocks, the Ultra 5 336H wins every benchmark, indicating the Panther Lake architecture and core count overcome the clock deficit. Memory support also differs: the i3-14100F supports DDR4 and DDR5, while the Ultra 5 336H supports DDR5 and LPDDR5X with a stated memory bandwidth of 115.2 GB/s. The i3-14100F supports ECC memory; the Ultra 5 336H does not. PCIe lanes are Gen 5 in both, but the i3-14100F offers 16 lanes versus 12 lanes for the Ultra 5 336H.

The i3-14100F has no integrated graphics, hence the F suffix. The Ultra 5 336H includes Intel Xe3 Graphics. The mobile chip also arrives with a later release date and a different socket, Intel BGA 2540, which is soldered rather than socketed.

Head-to-Head Benchmarks

The Cinebench suite shows a consistent 45.5% deficit for the i3-14100F across all six tests. In Cinebench R15 multicore, the Ultra 5 336H scores 2418 against 1318. In R15 single-core, the margin is 341 to 186. R20 multicore reads 10076 versus 5495, and R20 single-core reads 1422 versus 775. R23 multicore shows 23991 against 13084, while R23 single-core shows 3387 against 1847. The identical 45.5% delta across every Cinebench test suggests a fixed throughput ratio that scales evenly with the core count and architecture efficiency.

PassMark tests reveal wider variation. The smallest win for the Ultra 5 336H is PassMark single-thread and singlethread, both at 4013 versus 3778, a 5.9% margin. This indicates that per-core performance is relatively close; the desktop chip's higher boost clock helps narrow the gap in single-threaded workloads. The largest PassMark delta is prime number finding, where the Ultra 5 336H scores 299 versus 61, a 79.6% advantage. Floating point math also heavily favors the Ultra 5 336H: 82415 versus 35370, a 57.1% gap. Data encryption shows a 58.1% lead (21291 versus 8922), and physics simulation shows a 59.8% lead (2682 versus 1077).

Integer math is the closest multi-threaded PassMark discipline, with the Ultra 5 336H scoring 62070 versus 45357, a 26.9% lead. Data compression favors the Ultra 5 336H by 37.2% (280340 versus 176106), extended instructions by 51.2% (24542 versus 11984), random string sorting by 48.9% (34402 versus 17596), and multithread overall by 46% (28545 versus 15420). The pattern is clear: the more parallel or compute-dense the workload, the larger the Ultra 5 336H's lead, while single-threaded tasks narrow the gap but never flip it.

Where Each One Wins

The data shows the Core Ultra 5 336H wins every recorded benchmark, so the use-case split is less about which chip wins a given category and more about which platform constraints apply. The Ultra 5 336H dominates multi-threaded rendering: Cinebench R23 multicore scores 23991 versus 13084, a 45.5% lead, making it the stronger choice for CPU rendering workloads. PassMark physics shows a 59.8% lead (2682 versus 1077), indicating superior performance in simulation and physics computations. Floating point math, a proxy for scientific and engineering workloads, favors the Ultra 5 336H by 57.1% (82415 versus 35370). Encryption performance also leans heavily toward the Ultra 5 336H, with a 58.1% advantage (21291 versus 8922).

The i3-14100F has no benchmark wins, but its profile suits a different deployment context. It is a desktop processor on Intel Socket 1700 with a 58 W TDP and a $109 launch MSRP, making it a fixed-platform choice for users already committed to LGA1700 motherboards. It supports DDR4 memory, which can be a practical consideration for systems reusing older memory. ECC memory support is another differentiator that the Ultra 5 336H lacks, which matters for error-sensitive desktop workloads. Its 4.70 GHz boost clock is higher than the Ultra 5 336H's 4.60 GHz, and the PassMark single-thread gap is only 5.9% (4013 versus 3778), so lightly threaded desktop responsiveness is relatively close.

For mobile or compact systems, the Ultra 5 336H is the only option with a 25 W TDP versus 58 W, and it includes integrated graphics, eliminating the need for a discrete GPU. The i3-14100F requires a separate graphics card. The Ultra 5 336H also delivers 115.2 GB/s memory bandwidth with LPDDR5X support, a feature absent from the desktop part. Any workload that scales with core count, cache size, or memory bandwidth will favor the Ultra 5 336H, and the data confirms this across all 17 head-to-head tests.
