CPU Comparison
Intel Core i5-11500T vs Intel Core i9-11900T
A side-by-side comparison of specs, performance and value. The Intel Core i5-11500T is a low-power variant of the 11th Gen Rocket Lake lineup, designed for small form factor PCs and compact systems where thermal limits are strict. Operating at a mere 35W TDP, it drops the base clock to 1.5 GHz while maintaining a respectable 3.9 GHz turbo boost.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Snappy for daily tasks and office applications, though burst performance drops quickly under sustained load.
Snappy for office tasks, web browsing, and light multitasking, but heavier workloads expose its low base clock.
Gaming
Not intended for serious gaming; iGPU can handle older or 2D titles at low settings only.
Adequate for esports and older titles at 1080p with a discrete GPU, but struggles in modern CPU-demanding games.
Virtualization
Can run basic VMs, but limited power budget restricts multi-VM workloads.
Limited by core count and power limits for running multiple VMs.
Efficiency
Exceptional efficiency, drawing minimal power at idle and under load compared to 65W+ CPUs.
Excellent power efficiency under light loads, making it ideal for 24/7 always-on systems.
