The Core i5-11500T packs 6 cores / 12 threads, while the Core i5-1235U offers 10 cores / 12 threads — the Core i5-1235U has 4 more cores. Boost clocks reach 3.9 GHz on the Core i5-11500T versus 4.4 GHz on the Core i5-1235U — a 12% clock advantage for the Core i5-1235U (base: 1.5 GHz vs 1.3 GHz). The Core i5-11500T uses the Rocket Lake (2021) architecture (14 nm), while the Core i5-1235U uses Alder Lake-U (2022) (Intel 7 nm). In PassMark, the Core i5-11500T scores 12,730 against the Core i5-1235U's 12,740 — a 0.1% lead for the Core i5-1235U. Geekbench 6 single-core — the metric most relevant to gaming — records 1,818 vs 2,095, a 14.2% lead for the Core i5-1235U that directly translates to higher frame rates. Both processors carry 12 MB (total) of L3 cache.

The Core i5-11500T uses the LGA1200 socket (PCIe 4.0), while the Core i5-1235U uses FCBGA1744 (PCIe 5.0) — making them incompatible on the same motherboard. Maximum memory speed reaches DDR4-3200 on the Core i5-11500T versus LPDDR5-5200 on the Core i5-1235U — the Core i5-1235U supports 22.2% faster memory, which can translate to measurable gains in memory-sensitive workloads. The Core i5-11500T supports up to 128 GB of RAM compared to 64 GB — 66.7% more capacity for professional workloads. Both feature 2-channel memory with ECC support. Both provide 20 PCIe lanes.

Neither processor supports overclocking. Only the Core i5-11500T supports AVX-512 instructions — important for machine learning and scientific applications. Both support VT-x, VT-d, EPT virtualization. Both include integrated graphics — UHD Graphics 750 (Core i5-11500T) and Iris Xe Graphics 80EU (Core i5-1235U) — useful as a fallback for troubleshooting or display output without a dedicated GPU. Primary use case: Core i5-11500T targets Quiet Desktop / SFF, Core i5-1235U targets Mainstream Laptop. Direct competitor: Core i5-11500T rivals Core i5-10500T; Core i5-1235U rivals Ryzen 5 6600U.
