CPU Comparison
Intel Core i7-11700T vs Intel Core Ultra 5 135HL
A side-by-side comparison of specs, performance and value. The Intel Core i7-11700T is a low-power desktop processor from the Rocket Lake-S family, released in March 2021. Featuring 8 cores and 16 threads, it is built on a 14nm process and designed for small form factor (SFF) PCs where thermal and power constraints are critical. With a base clock of just 1.4 GHz and a max turbo of 4.6 GHz, it operates at a strict 35W TDP. Despite the low power limit, it includes 16 MB of L3 cache and supports PCIe 4.0 with 20 lanes. It also features integrated UHD Graphics 750, making it suitable for systems without a dedicated GPU. The 11700T is ideal for office environments, HTPCs, and compact builds that require reliable multi-threaded performance without the heat output of standard 65W or 125W desktop chips.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles office tasks and moderate compilation well, but slows down in sustained all-core workloads.
Higher base clock speeds improve snappiness in everyday applications.
Gaming
The low base clock can cause stuttering in CPU-heavy games unless the turbo is aggressively sustained.
The 128EU Arc graphics provide a noticeable bump in light gaming frame rates compared to the 125HL.
Virtualization
8 cores are nice, but power limits throttle heavy VM deployments.
Suitable for light virtualization, though still limited by 8 CPU PCIe lanes.
Efficiency
Outstanding efficiency, drawing minimal power at idle and under load.
Maintains excellent power efficiency despite the higher clock speeds.
Specialized Performance
AI / ML
- Not suitable for heavy AI workloads due to power throttling
- 11 TOPS NPU for background AI tasks
- Improved graphics rendering for AI-assisted tools
- Supports DLBoost 3.0 and AI Boost NPU 3
Content Creation
Gaming
- Low base clock affects minimum FPS
- Fine for casual or older games
- Pair with a low-power GPU for best results
- 128EU Arc Xe-LPG handles light gaming better than 112EU
- Still not a replacement for a discrete GPU in AAA titles
- CPU PCIe lanes limit high-end dGPU configurations
