Where Each One Wins

The Arc G3 EXTREME is the stronger choice for workloads that depend on floating point arithmetic, encryption, and physics calculations. The PassMark floating point math result of 86929 against 61319, the data encryption result of 23881 against 16949, and the physics result of 2515 against 1523 all point in the same direction. The find prime numbers result, 248 versus 86, reinforces this pattern. The Arc G3 EXTREME also handles multithreaded PassMark workloads better, with 30659 versus 25470, and it shows a clear lead in extended instructions and random string sorting.

The Core i5-14400F is the better option for Cinebench R23 workloads. Its multicore score of 21645 is far ahead of the Arc G3 EXTREME's 14655, and its singlecore score of 3055 beats 1862. This suggests a significant advantage in rendering and single-threaded CPU tasks as measured by that benchmark. The Core i5-14400F also wins in integer math, with 81524 versus 71164, and in data compression, with 315521 versus 307094. The Cinebench R15 multicore result is effectively tied at 2192 versus 2181, so neither chip has a meaningful edge in that specific test.

The split is not simply multicore versus singlecore. The Arc G3 EXTREME wins Cinebench R20 in both categories, while the Core i5-14400F wins Cinebench R23 in both categories. The PassMark single thread test goes to the Arc G3 EXTREME by 16%, but the Cinebench R15 and R23 singlecore tests go to the Core i5-14400F. These results indicate that the two processors respond differently to the specific instructions and workloads used by each benchmark suite.

Specification Differences

The two processors differ in core count. The Arc G3 EXTREME has 14 cores and 14 threads. The Core i5-14400F has 10 cores and 16 threads. The base clock differs as well: the Arc G3 EXTREME runs at 1.90 GHz, and the Core i5-14400F runs at 2.50 GHz. Both have a boost clock of 4.70 GHz.

The thermal design power is distinct. The Arc G3 EXTREME has a TDP of 25 watts, while the Core i5-14400F has a TDP of 65 watts. The sockets are different: the Arc G3 EXTREME uses Intel BGA 2540, and the Core i5-14400F uses Intel Socket 1700. The Arc G3 EXTREME is classified as a mobile processor, while the Core i5-14400F is classified as a desktop processor.

Cache configurations differ. The Arc G3 EXTREME has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. The Core i5-14400F has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 20 MB of shared L3 cache. The die size also differs, with the Core i5-14400F measuring 215 mm², while the die size for the Arc G3 EXTREME is not recorded.

Memory support is another point of divergence. The Arc G3 EXTREME uses LPDDR5X with dual-channel support and a recorded memory bandwidth of 136.5 GB/s. The Core i5-14400F supports DDR4 and DDR5 with dual-channel support, and no memory bandwidth figure is recorded. ECC memory is supported on the Core i5-14400F but not on the Arc G3 EXTREME. PCIe lanes differ: the Arc G3 EXTREME provides Gen 5 with 4 lanes, and the Core i5-14400F provides Gen 5 with 16 lanes. The Arc G3 EXTREME includes integrated graphics in the form of Arc B390, while the Core i5-14400F has no integrated graphics.

Architecture Differences

The Arc G3 EXTREME is built on Panther Lake architecture and uses a 3 nm process node. The Core i5-14400F uses Raptor Lake architecture, specifically Raptor Lake-R, on a 10 nm process node. Both are manufactured by Intel. The Arc G3 EXTREME is part of the Arc G3 generation, and the Core i5-14400F is part of the Core i5 generation under the Raptor Lake Refresh codename.

The process node difference is significant. The 3 nm node on the Arc G3 EXTREME is several generations ahead of the 10 nm node on the Core i5-14400F. This helps explain the large TDP gap, with the Arc G3 EXTREME drawing 25 watts versus 65 watts for the Core i5-14400F, despite the Arc G3 EXTREME having more physical cores.

The production status for both is Active. The release dates are different: the Arc G3 EXTREME was released on 2026-05-27, and the Core i5-14400F was released on 2024-01-07. Neither processor has an unlocked multiplier. The Core i5-14400F has part numbers SRN3RSRN47, and the Arc G3 EXTREME has part number SA4R3.

The Verdict

The data supports a clear division of use cases. The Intel Arc G3 EXTREME delivers better results in most recorded benchmark tests, winning 12 of 17 comparisons. Its strengths in floating point math, encryption, physics, and multithreaded PassMark workloads make it the stronger performer in those categories. The 188.4% lead in find prime numbers and the 65.1% lead in physics are particularly pronounced. The 3 nm process node and 25 watt TDP also position it as the more efficient design on paper, and the integrated Arc B390 graphics add capability that the Core i5-14400F lacks entirely.

The Intel Core i5-14400F is the better choice for Cinebench R23 workloads. The 32.3% multicore advantage and 39.1% singlecore advantage are decisive in that benchmark. It also leads in integer math and data compression. The 10-core, 16-thread configuration with 20 MB of L3 cache and a 65 watt TDP suits desktop platforms, and the Socket 1700 interface aligns with established desktop motherboards. The support for DDR4 and DDR5 memory and the inclusion of ECC support add flexibility for systems that require those features.

The average benchmark scores place the Arc G3 EXTREME at 36699 and the Core i5-14400F at 32279, a difference of roughly 13.7%. The percentile rankings are close, 85th versus 83rd, which suggests that both processors sit near each other in the broader CPU landscape despite the different workload profiles.

For users whose workloads resemble the PassMark suite, particularly math, encryption, and physics calculations, the Arc G3 EXTREME is the stronger option. For users whose workloads resemble Cinebench R23, especially rendering and single-threaded tasks, the Core i5-14400F holds the advantage. The choice depends on which benchmark set better represents the intended use.
