HD 7970: Bulldozer vs. Sandy Bridge vs. Nehalem [TPU]

[Blín D'ñero]

In this review we will pit three CPUs from the popular ~$250 segment against each other using the Radeon HD 7970:
•AMD FX-8150: This is the company's current flagship Bulldozer processor. It features four execution units that show up as eight cores in Windows, its Turbo clocks up to 4.2 GHz and it has plenty of cache, the processor is priced competitively at $270.
•Intel Core i5-2500K: The processor most gamers and overclockers use. Thanks to its "K" suffix it enables significant overclocking unlike the cheaper Sandy Bridge processors, yet comes at an affordable price of $220. Actually this makes it the cheapest processor in today's test group.
•Intel Core i7-920: While it does not use a sexy 32 nm production process and is based on Intel's last generation Nehalem architecture, it still packs a punch especially when overclocked. It is also an affordable choice if you are looking to run a multi-GPU gaming rig at full 2x PCIe x16 without breaking the bank (LGA 2011).

I don't understand why they did not run them all at 3.8 Ghz, i7-920 is an extremely easy overclocker, to get apples to apples.
In crossfire the LGA1155 does not provide 2 x 16x, like the 1366 does (it's mentioned in the verdict) with i7-920.

Which gamer, with an Intel Core i7-920 runs it at 2.66 GHz with only turboboost to get some punch? Instead, you make sure you have a good motherboard and put the values in manually to overclock it at least to 3.8 Ghz.
The review is for out-of-the-box experience. But i understand the AMD CPU is made for Windows 8, and overclocking?
Seems a useless meaningless review to me.

Apples-to-apples . AMD Bulldozer / FX-8150 Gameplay Performance Review HardOCP

Ah... thanks to this article we can see in the typical firstpersonshooter and raceing game no advantage to overclocking the CPU, only in the typical strategic game Civilisation V.

Verdict Except in Civilization V no difference in gameplay at all settings low to high, cpu at stock to overclocked.
