Intel Arc G3 vs Intel Core i5-14400T Comparison

The Verdict

The Intel Arc G3 and Intel Core i5-14400T target entirely different segments, and the recorded data reflects that split. The Core i5-14400T is a desktop processor with a full benchmark suite, an average benchmark score of 27166, and a percentile rank of 79 among all CPUs. The Arc G3, by contrast, is a mobile part on Intel BGA 2540 with a 25 TDP, no recorded benchmark scores, an average benchmark score of 0, and a percentile rank of 50. The database shows no head-to-head benchmark entries for these two processors, and the Arc G3 has zero wins while the Core i5-14400T also has zero wins in direct comparisons.

The Core i5-14400T is the only one of the two with measurable performance data. Its nearest rivals in the database include the Intel Core i9-9900K with an average score of 27097 and a delta of 0.3%, the AMD Ryzen 7 5700G at 27051 with a delta of 0.4%, the Intel Core i7-13700H at 27355 with a delta of -0.7%, and the AMD Ryzen 3 PRO 5355G at 27382 with a delta of -0.8%. This places the i5-14400T in a tight cluster around the 27000 to 27400 mark, effectively trading places with older high-end desktop parts and a recent mobile H-series chip.

The Arc G3 cannot be assessed on performance grounds from the available data. It has no benchmarks, no rivals, and no average score. The selection between these two processors is therefore a choice between a measured desktop part with established results and a mobile part with no recorded measurements. The data supports choosing the Core i5-14400T for any workload where performance needs to be verified against the database, while the Arc G3 remains an unquantified entry in the mobile segment.

Where Each One Wins

The Core i5-14400T wins in every measurable category because it is the only processor with benchmark data. Its Cinebench results show a multi-core score of 1732 in R15, 7219 in R20, and 17189 in R23. Single-core scores are 244 in R15, 1018 in R20, and 2426 in R23. PassMark results include a multi-thread score of 20223, a single-thread score of 3512, integer math at 65667, floating point math at 49139, extended instructions at 14562, data compression at 235636, data encryption at 13244, physics at 1244, random string sorting at 25181, and prime number finding at 73.

The Arc G3 has no wins because it has no recorded scores. Its specifications do suggest a different role: it uses LPDDR5X memory with a dual-channel bus and 136.5 GB/s of memory bandwidth, while the Core i5-14400T supports DDR4 and DDR5 with no bandwidth figure recorded. The Arc G3 also carries the Arc B370 integrated graphics, compared to the UHD Graphics 730 on the Core i5-14400T. The mobile part draws 25 TDP versus 35 TDP for the desktop part, and it runs on a 3 nm process node from Intel, whereas the Core i5-14400T uses a 10 nm node.

The use-case split is clear: the Core i5-14400T is the desktop workhorse with verified scores across rendering, math, encryption, and compression workloads. The Arc G3 is a low-power mobile processor with a newer process node, faster memory support, and a more capable integrated GPU, but the database contains no performance evidence for it.

Architecture Differences

The two processors diverge on nearly every architectural axis. The Arc G3 is built on Panther Lake, a 3 nm Intel process, while the Core i5-14400T uses Raptor Lake-R on a 10 nm Intel process. The Arc G3 has 14 cores and 14 threads, meaning it uses no simultaneous multithreading. The Core i5-14400T has 10 cores and 16 threads, indicating a mix of performance and efficiency cores with hyper-threading on the performance side.

Cache layouts differ substantially. The Arc G3 has 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Core 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 therefore has more per-core L1 and L2, while the Core i5-14400T has more total L3. The die size for the Core i5-14400T is recorded at 215 mm²; no die size is recorded for the Arc G3.

Clock speeds are similar on paper. The Arc G3 has a base clock of 1.90 GHz and a boost clock of 4.60 GHz. The Core i5-14400T has a base clock of 1.50 GHz and a boost clock of 4.50 GHz. The Arc G3 has a slight edge on both figures. Power targets flip the comparison: the Arc G3 is rated at 25 TDP, the Core i5-14400T at 35 TDP.

Memory and platform differences are significant. The Arc G3 uses LPDDR5X on a dual-channel bus with 136.5 GB/s of bandwidth. The Core i5-14400T supports DDR4 and DDR5 on a dual-channel bus with no bandwidth figure recorded. The Core i5-14400T supports ECC memory; the Arc G3 does not. PCIe connectivity also differs: the Arc G3 offers Gen 5 with 4 lanes for the CPU, while the Core i5-14400T offers Gen 5 with 16 lanes.

The sockets are incompatible. The Arc G3 uses Intel BGA 2540, a soldered mobile socket, while the Core i5-14400T uses Intel Socket 1700, a desktop LGA socket. The Arc G3 is a mobile part, the Core i5-14400T is a desktop part. Both are active in production, neither has an unlocked multiplier, and both come from Intel.

The integrated graphics differ as well. The Arc G3 pairs with Arc B370, while the Core i5-14400T uses UHD Graphics 730. The release dates are far apart: the Core i5-14400T launched in January 2024, the Arc G3 in May 2026.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the Intel Arc G3 and the Intel Core i5-14400T. The wins counter shows zero for both processors. This absence of direct measurements means any comparison must rely on the Core i5-14400T's standalone scores and the Arc G3's lack of them.

The Core i5-14400T's Cinebench R23 multi-core score of 17189 places it 0.3% above the Intel Core i9-9900K and 0.4% above the AMD Ryzen 7 5700G in average benchmark score, while sitting 0.7% below the Intel Core i7-13700H and 0.8% below the AMD Ryzen 3 PRO 5355G. Its Cinebench R20 multi-core score of 7219 and R15 multi-core score of 1732 follow the same pattern of solid mid-range desktop performance. Single-core results are equally consistent: 2426 in R23, 1018 in R20, and 244 in R15.

PassMark results show the Core i5-14400T with 20223 in multi-thread and 3512 in single-thread. Integer math scores 65667, floating point math scores 49139, and extended instructions score 14562. Data compression reaches 235636, data encryption reaches 13244, and random string sorting reaches 25181. Physics scores 1244 and prime number finding scores 73. These figures establish the Core i5-14400T as a measured, mid-range desktop processor.

The Arc G3 has no comparable figures. Its average benchmark score of 0 and empty benchmark array mean the database records no Cinebench, PassMark, or any other performance result for it. The 50th percentile rank is a default position, not a measured one. The Core i5-14400T, with its 79th percentile rank and 27166 average score, is the only processor in this pairing with verifiable performance data.
