Architecture Differences

The two processors diverge sharply in their underlying designs. The Arc G3 EXTREME uses the Panther Lake codename on a 3 nm process node, fabricated by Intel, and is built for the mobile segment with an Intel BGA 2540 socket. It features 14 cores and 14 threads, with a base clock of 1.90 GHz and a boost clock of 4.70 GHz. The Core i5-14400 belongs to the Core 14th Gen series with the Raptor Lake-R codename, uses a 10 nm process node, targets the desktop segment with an Intel Socket 1700, and has 10 cores and 16 threads. Its base clock is 2.50 GHz with the same 4.70 GHz boost clock. The thread count disparity is notable: the i5-14400 has fewer cores but more threads, indicating hyper-threading support that the Arc G3 EXTREME does not employ.

Cache layouts also differ. The Arc G3 EXTREME carries 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Core i5-14400 has 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3. The larger per-core L1 and L2 on the Arc G3 EXTREME may contribute to its strong performance in latency-sensitive workloads, while the i5-14400's larger shared L3 of 20 MB provides more pooled capacity. The i5-14400 has a die size of 215 mm², a figure not recorded for the Arc G3 EXTREME.

Memory and platform features separate them further. The Arc G3 EXTREME supports LPDDR5X memory over a dual-channel bus with a recorded bandwidth of 136.5 GB/s, while the Core i5-14400 supports DDR4 and DDR5 with no bandwidth figure recorded. The Arc G3 EXTREME does not support ECC memory; the Core i5-14400 does. PCIe connectivity differs as well: the Arc G3 EXTREME provides Gen 5 with 4 lanes (CPU only), while the Core i5-14400 provides Gen 5 with 16 lanes (CPU only). Integrated graphics also differ, with the Arc G3 EXTREME using Arc B390 and the Core i5-14400 using UHD Graphics 730. The power profile is distinct, with the Arc G3 EXTREME rated at 25 W TDP and the Core i5-14400 at 65 W TDP. The Arc G3 EXTREME launched on 2026-05-27, while the Core i5-14400 launched on 2024-01-07. The Core i5-14400 has a launch MSRP of $221. The Arc G3 EXTREME has no recorded launch MSRP.
