AMD FX "Bulldozer" Review - (4) !exclusive! Excuse for 1-Threaded Perf.

[dess]

We are talking well over a 300 mhz variance clock hit with a 4cu/4core versus a hypothetical 4170 when it comes to stability for 24/7 useage.

300 MHz is 6% of 5 GHz, while the gain in performance on 4CU/4C is up to 26% C2C! How is it not worth it?

Problem is if core 2 = disabled then core 3 must be disabled, and so on.

Do you mean you cannot enable core 3, even if you want, or it's just affecting OC badly?

Could it be that the "deactivation" allows the threads to use the resources of the CU more efficiently (turning off a cluster may not turn off its resources, just the "thread" showing up as a core to windows) thus generating slightly more power usage?

I'm not sure how you mean it, but it definitely consumes less than all cores enabled (C2C):
