Specification context
What do these specifications mean in practice?
The Intel U300L is a Mobile/Embedded released in 2025. Recorded specifications include a 15 W reference TDP, a 8,385 CPU Mark. Use these figures to understand its position, then compare the results with your software and the complete platform.
Read the performance results
The 8,385 CPU Mark is a broad overall-performance measure, while the 2,914 single-thread result adds context for less-parallel work. Compare the nearby alternatives on this page and do not treat one score as a verdict for every application.
Platform and compatibility
No confirmed socket is recorded for this processor. Verify the exact device or motherboard with the manufacturer before planning an upgrade.
Memory and power
Recorded memory support: DDR5-5200. The 15 W TDP helps size the cooling class, but it is not the same as peak wall-power consumption.
FAQ
Common processor questions
What are the key Intel U300L specifications?
The main recorded details are a 15 W reference TDP, a 8,385 CPU Mark. The tables on this page show socket, memory, cache and graphics data when available.
