The performance of ultra-compact form-factor (UCFF) desktops has improved significantly over the years, thanks to advancements in semiconductor fabrication and processor architecture. Thermal solutions suitable for these 4in. x 4in. machines have also been evolving simultaneously. As a result, vendors have been able to configure higher sustained power limits for the processors in these systems. With Intel and AMD allowing configurable TDPs for their notebook segment offerings, UCFF systems with regular 45W TDP processors (albeit, in cTDP-down mode) are now being introduced into the market.
