Desktop
The Intel Core i5-12500T is a 6-core, 12-thread low-power desktop processor that excels in thermally constrained builds. Operating at a 35W base TDP, it delivers exceptional efficiency without sacrificing core count. It features 18MB of L3 cache and boosts up to 4.4 GHz, offering snappy performance for everyday computing and moderate workloads. Equipped with UHD Graphics 770, it provides excellent multi-display support and video decode capabilities. This makes it an ideal choice for small form factor (SFF) PCs, home servers, and office rigs where quiet operation and low heat are prioritized.
The Intel Core i5-12500T combines 6 high-performance cores with a low 35W TDP for cool and quiet operation. It differentiates itself from the 12400T with UHD 770 graphics, enabling better 3D rendering and quad-display outputs. Reaching up to 4.
4 GHz, it is a versatile chip for SFF and office builds.

Architecture Overview
The Alder Lake-S 12500T uses a homogeneous core layout, relying entirely on 6 Golden Cove performance cores. This ensures that every thread has access to the highest performance capabilities, without relying on background E-cores.
CPU Design
6 P-cores with Hyper-Threading provide 12 high-performance threads, making it ideal for applications requiring consistent thread performance.
Memory Subsystem
Supports both DDR4 and DDR5, allowing builders to choose between budget-friendly and future-proof memory platforms.
PCIe & I/O
20 PCIe lanes directly from the CPU (16 Gen 5 + 4 Gen 4) ensure ample bandwidth for GPUs and fast storage.
Overclocking
Locked multiplier, but power limit unlocking on B660 boards can sustain higher clocks.
- Significant IPC uplift
- UHD 770 vs UHD 750
- DDR5 and PCIe 5.0
Key Highlights

History
The Core i5-12500T launched as the sweet spot for users needing strong iGPU capabilities in a low-power envelope. Previously, finding a CPU with decent multi-display support and a 35W TDP was difficult. The 12500T solved this by pairing 6 robust P-cores with the UHD 770 iGPU, becoming a favorite for SFF enthusiasts and home server builders who relied on Intel Quick Sync for media transcoding without needing a power-hungry discrete GPU.
