Core 2 Duo E8400 vs Pentium Dual-Core E5400 | Hardlimit Benchmark Central

Core 2 Duo E8400 vs Pentium Dual-Core E5400

The Core 2 Duo E8400 and Pentium Dual-Core E5400 monothread performance are slightly different but they have an identical multithread performance. These two models were released almost at the same time which doesn't explain their performance difference so we should check if they belong to the same range.
