Reviews Word on the street

Core i5 2500K  vs FX 8350 

The Core i5-2500K also lacks Intel's Hyper-Threading technology, which means its four cores generate a maximum of four processing threads rather than the Core i7-2600K's eight, and that you can expect a drop in performance when working in highly threaded applications.
Core i5 2500K

In terms of 3D performance, the detail spec changes include an upgrade from DX10 to DX10.

I would get a 8350 because of DX12 oh and the benchmarks are better.
The i5-2500k is a legendary CPU.
YES IT DOES...BUT...if you compare price of this two??wich you will buy...my opinion FX 8350 kick ass in most of bench"s and overall
For a old 4 cores the I5 2500K is a beast, and today it is
Hi! AMD FX 83XX is very good processors! ;) Intel i5 2500K (LGA1155) Intel status: End of life.
If they both score 8.2, doesn't that make it a tie? The best recommendation would be to say get the 2500K if you need the best single-core performance, the FX-8350 if you use primarily software that is multi-threaded.
Intel biased match of these CPUs. Intel only beats the AMD in single core performance in this comparison, AMD, however, beats this Intel in the other benchmarks. Sorry but the AMD wins this match overall.
