Our Verdict on Each
An excellent choice for mid-range gaming and productivity, offering good single-core speeds, PCIe 4.0, and integrated graphics for troubleshooting.
Best for: Building a mid-range gaming PC on the LGA 1200 platform.
Read the full reviewAn excellent low-TDP processor for SFF builds, offering 6 cores and PCIe 4.0 with minimal heat output.
Best for: The Intel Core i5-11400T is highly recommended for builders constructing a small form factor PC, home theater PC, or a silent office workstation. Its 35W TDP means it can be cooled passively or with a low-RPM fan, ensuring a completely silent computing experience. It is perfect for 1080p media playback, light office work, and web browsing. However, it is not advisable for gaming or heavy content creation, as its low base clock of 1.3 GHz will bottleneck modern GPUs and slow down rendering tasks significantly. If your primary goal is a compact, energy-efficient system that runs 24/7 without generating excess heat, the 11400T is an excellent choice. Just ensure you pair it with fast NVMe storage to leverage the PCIe 4.0 lanes, maximizing system responsiveness for everyday tasks.
