The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Lacks threads for heavy productivity.
Snappy for daily tasks but fails in multi-threaded rendering.
Gaming
Still performs well in gaming when paired with mid-range GPUs.
High clocks help older games, but 4 threads cause severe stuttering in modern titles.
Virtualization
Not ideal due to 6 thread limit.
Poor for VMs due to lack of threads.
Efficiency
Can draw significant power when overclocked.
91W TDP increases significantly when overclocked.
