Core i5-12400T vs Core i5-11500H

Both the Core i5-12400T and Core i5-11500H share an identical 6-core/12-thread configuration. Boost clocks reach 4.2 GHz on the Core i5-12400T versus 4.6 GHz on the Core i5-11500H — a 9.1% clock advantage for the Core i5-11500H (base: 1.8 GHz vs 2.9 GHz). The Core i5-12400T uses the Alder Lake-S (2022) architecture (Intel 7 nm), while the Core i5-11500H uses Tiger Lake H45 (2021) (10 nm SuperFin). In PassMark, the Core i5-12400T scores 15,543 against the Core i5-11500H's 15,669 — a 0.8% lead for the Core i5-11500H. Geekbench 6 single-core — the metric most relevant to gaming — records 1,650 vs 1,801, a 8.8% lead for the Core i5-11500H that directly translates to higher frame rates. Multi-core Geekbench: 7,800 vs 6,248 (22.1% advantage for the Core i5-12400T). L3 cache: 18 MB (total) on the Core i5-12400T vs 12 MB (total) on the Core i5-11500H.

The Core i5-12400T uses the LGA1700 socket (PCIe 5.0), while the Core i5-11500H uses FCBGA1787 (PCIe 4.0) — making them incompatible on the same motherboard. Maximum memory speed reaches DDR5-4800 on the Core i5-12400T versus DDR4-3200 on the Core i5-11500H — the Core i5-12400T supports 22.2% faster memory, which can translate to measurable gains in memory-sensitive workloads. Both support up to 128 GB of RAM. Both feature 2-channel memory with ECC support. Both provide 20 PCIe lanes. Chipset compatibility: H610,B660,H670,Z690 (Core i5-12400T) and HM570,QM580,WM590 (Core i5-11500H).

Neither processor supports overclocking. Only the Core i5-11500H supports AVX-512 instructions — important for machine learning and scientific applications. Both support VT-x, VT-d, EPT virtualization. Both include integrated graphics — Intel UHD Graphics 730 (Core i5-12400T) and UHD Graphics 750 (32 EU) (Core i5-11500H) — useful as a fallback for troubleshooting or display output without a dedicated GPU. Primary use case: Core i5-12400T targets Office/Home Desktop, Core i5-11500H targets Gaming. Direct competitor: Core i5-11500H rivals Ryzen 5 5600H.
