Architecture Differences

The two processors come from completely different design generations and target different market segments. The Intel Arc G3 EXTREME is a mobile processor built on Panther Lake architecture, fabricated on a 3 nm process by Intel. The Intel Core i5-14400T is a desktop processor using Raptor Lake architecture, specifically Raptor Lake-R, on a 10 nm process. The process node difference alone explains much of the efficiency and performance-per-watt gap observed in the benchmarks.

Core counts differ significantly. The Arc G3 EXTREME has 14 cores and 14 threads, meaning it uses only single-threaded cores with no hyperthreading. The i5-14400T has 10 cores and 16 threads, meaning it uses a hybrid configuration with some cores supporting two threads each. Despite having 4 more physical cores, the Arc G3 EXTREME still trails in Cinebench R23 multicore, which suggests the i5-14400T's thread count and Raptor Lake architecture are better optimized for that specific rendering workload.

Clock speeds are close but favor the Arc G3 EXTREME. The Arc G3 EXTREME has a base clock of 1.90 GHz and a boost clock of 4.70 GHz. The i5-14400T has a base clock of 1.50 GHz and a boost clock of 4.50 GHz. The Arc G3 EXTREME also has a lower TDP of 25 watts versus 35 watts for the i5-14400T, which is notable given that the Arc G3 EXTREME delivers higher performance in most benchmarks while drawing less power on paper. This efficiency advantage aligns with the newer 3 nm process.

Cache layouts are quite different. 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 i5-14400T has 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3. The Arc G3 EXTREME's larger per-core L1 and L2 caches likely contribute to its strong PassMark results, particularly in integer math and data compression, where cache locality matters. The i5-14400T's larger shared L3 cache may help in the Cinebench R23 workload, which can utilize larger working sets.

Memory support differs as well. The Arc G3 EXTREME uses LPDDR5X memory with dual-channel support and a measured memory bandwidth of 136.5 GB/s. The i5-14400T supports both DDR4 and DDR5, also dual-channel, but no bandwidth figure is recorded in the database. The Arc G3 EXTREME does not support ECC memory, while the i5-14400T does. PCIe connectivity also differs: the Arc G3 EXTREME provides Gen 5 with 4 lanes, while the i5-14400T provides Gen 5 with 16 lanes. The i5-14400T offers more PCIe lanes for expansion, which is typical for a desktop part.

Integrated graphics differ substantially. The Arc G3 EXTREME carries an Arc B390 iGPU, while the i5-14400T uses UHD Graphics 730. The Arc B390 is a more capable graphics solution, consistent with the Arc G3 EXTREME's mobile and multimedia orientation. The i5-14400T has a die size of 215 mm², while no die size is recorded for the Arc G3 EXTREME. The i5-14400T uses Socket 1700, while the Arc G3 EXTREME uses Intel BGA 2540, confirming the former is socketed for desktop builds and the latter is soldered for mobile systems.

Release dates also differ. The i5-14400T was released on 2024-01-07, with a launch MSRP of $221. The Arc G3 EXTREME was released on 2026-05-27 and has no recorded launch MSRP. Both parts are currently marked as Active in production status. Neither processor has an unlocked multiplier.

The Verdict

The data paints a clear picture of two processors built for different roles. The Intel Arc G3 EXTREME dominates the majority of benchmark comparisons, winning 15 of 17 tests with particularly large margins in math-heavy and encryption workloads. Its 85th percentile ranking against all CPUs and average benchmark score of 36699 place it well above the i5-14400T's 79th percentile and 27166 average. The Arc G3 EXTREME is the stronger performer for most general-purpose and compute-intensive tasks.

The Intel Core i5-14400T should be chosen when Cinebench R23 performance is the priority. It leads by 14.7% in R23 multicore and 23.2% in R23 singlecore. These are rendering-specific workloads, and the i5-14400T's hybrid core design with 16 threads appears better suited to that particular benchmark. The i5-14400T also offers ECC memory support and 16 PCIe Gen 5 lanes, which are meaningful for certain workstation and reliability-oriented use cases. Its Socket 1700 platform allows for upgradeability in a desktop context.

The Arc G3 EXTREME is the better choice for users who need maximum throughput across a broad range of workloads. Its wins in PassMark multithread (51.6%), floating point math (76.9%), data encryption (80.3%), and physics (102.2%) demonstrate a processor that handles diverse computational tasks with authority. The 3 nm process and 25 watt TDP also indicate strong efficiency, which is relevant for mobile deployments where thermal and power constraints matter. The Arc G3 EXTREME's larger per-core caches and newer architecture give it an edge in most measured scenarios.

For desktop builders who prioritize Cinebench R23 rendering scores and need ECC memory or a high lane-count PCIe interface, the i5-14400T is the appropriate choice. For anyone who wants the higher overall benchmark average and the broader set of wins, the Arc G3 EXTREME is the stronger option. The data does not support a single universal winner; it supports a workload-dependent decision.
