FX-4130 vs 975: comparison
Comparison of FX-4130 and 975: key differences and a full specification table.
Key differences
FX-4130 has a higher base clock (3.8 GHz vs 3.6 GHz) and a finer process node (32 nm vs 45 nm).
At the same time, 975 has a larger L3 cache (6 MB vs 4 MB).
Both processors match on: core count (4), thread count (4), TDP (125 W).
These are specification values: they show differences between the models but do not determine a performance winner. For a specific workload, rely on independent benchmarks.
