AMD Phenom II X4 965BE Rev C3

Testbed & Temperatures

Test Bed
AMD Phenom II X4 965 Black Edition "C3" 
Gigabyte MA770T UD3P Motherboard
4GB Corsair XMS3-1333 C9 RAM
Asus Radeon HD 5850 1GB GDDR5 Graphics Card
Samsung Spinpoint F1 320GB SATA II HDD
OCZ StealthXStream 500W ATX 2.0 PSU
Arctic Freezer 7 Pro CPU Cooler
Windows Vista Home Premium SP1 64bit
The system had been prepared such to simulate a typical configuration that may include a Phenom II X4 965 Black Edition. This includes a set of mid to upper midrange components. No unconventional components that may skew the results have been used.
The Gigabyte MA770T UD3P was flashed to the latest "F4" BIOS for formal C3 Microcode CPU support. While most (if not all) motherboards that support the previous Deneb Core CPU's will boot straight out of the box, formal support is essential to ensure optimal stability and the highest overclock possible.
We were pleasantly surprised by the CPU's Temperatures. With ambients of 22*c the CPU topped at 54*c during the OCCT LinPack test which is notorious for being unnaturally hard on the CPU. The Arctic Freezer 64 Pro was not operating at full fan duty speed. It would seem as though Overclocking Headroom has the potential to be pretty good. There's only one way to find out for sure...

Great stuff.

Thing interesting me is what market is open for these AMD cpus.

I feel they need to provide a 'need' to buy an AMD cpu. Existing AM2/3 owners will see them as attractive, but this market I think is both small and arguably only getting smaller.

If u have even an existing 775 setup, do u switch ? (similar argument to changing to anything - age of components maybe)

If ur older setup craps out, do u go AM2/3 or iX/775 ?

Without being an immediate 'got to get' I think it's too easy to overlook them. I can think of 100s of people who recognize these, and previous AMD models, are damn fine cpus - very respectable, and yet when the crunch comes they still won't go AMD<-Intel.

They need something. I've been a long advocate of them doing something special between their cpus and gpus. Something special that if u have 1 of the group, u can't experience, yet coupled together u get.... something.... They've got both techs in their labs for years now, it's about time they pushed something unique.Quote

It would be something to see some kind of "synergy" between their CPU's and GPU's though we'll see how something like that could be implemented beyond just hot air from the marketing department.

As it stands, AMD is playing the "bang per buck" game however this has diminished with the arrival of the Core i5 750. The 965BE and i5 750 exchange punches on the gaming front but it's all over when we start factoring in overclocking headroom.

While overclocking yields have improved (as shown) it still has nothing on the Core i5/i7 processors which (heatsink allowing) tends to have little trouble reaching 4.0GHz. AMD are also able to tout good results with their system platform as they already have a strong graphics card and right now, much of today's games seem to have enough GPU dependancy for the CPU to take a back seat (within reason of course).

This competitive bang per buck edge will diminish to some extent over the next year, although their Thuban 6 core CPU will help gain some more sales. Unfortunately for AMD, they will have to let Intel pound ahead in the upper high end until Bulldozer is alive and kicking.Quote
