Hardware Secrets posted a round-up review comparing the performance of Celeron E1400, Pentium Dual Core E2180 and Athlon X2 4600+

"Today we put together a review comparing the performance of entry-level CPUs on the USD 70 price range: Celeron E1400 (dual-core 2 GHz), Pentium Dual Core E2160 (1.8 GHz), Pentium Dual Core E2180 (2 GHz) and Athlon X2 4600+ (2.4 GHz). With this review we wanted to answer a simply question: which one is the best USD 70 CPU today? We also included on this round-up a Core 2 Duo E4400 (2 GHz). We know that this CPU isn't on this price range (and not even sold in the US anymore), but we were curious to compare a Celeron, a Pentium Dual Core and a Core 2 Duo all running under the same clock rate (2 GHz in our case) to see what is the performance difference between these Intel CPUs. Which CPU is the winner? Read on!"
