Our Verdict on Each
An efficient 6-core chip that trades raw clock speed for a strict 35W thermal envelope, making it perfect for compact systems but less ideal for heavy workloads.
Best for: Building or upgrading a low-power, small form factor system where a 35W TDP is strictly required.
Read the full reviewAn excellent choice for compact systems needing 8-core efficiency without the heat of standard desktop processors.
Best for: Building a quiet small form factor PC
