Phenom II X4 965 BE Overclock Results

Overclocking the Phenom II X4 965's core frequency was a breeze thanks to its unlocked Black Edition multiplier. As we've seen with the rest of the Phenom II family, this processor also benefits from overclocking the cpu-northbridge. Changing this frequency directly impacts the memory controller and L3 cache. To illustrate the point, I've run our benchmarks at four different settings. Up first are the stock results, which I simply copied over from the previous pages for reference. I then overclocked just the northbridge to 2.8 GHz to see what kind of effect it had. Following those benchmarks, I set the northbridge back to stock and overclocked just the core frequency to 3.9 GHz. Finally, I combined the two for a total of 3.9GHz core frequency and 2.8 GHz northbridge frequency. The results are below.

The memory benchmarks clearly demonstrate the importance of the northbridge frequency. As expected, the northbridge-only overclock and the northbridge+CPU overclock perform the best. The CPU-only overclock does show some improvement over stock, but not nearly as much as when combined with an overclocked northbridge.

Moving on to the CPU benchmarks, the results are reversed. The Everest AES and Queen tests, as well as PCMark05's CPU test, do an excellent job of isolating the CPU. In these benchmarks, overclocking the northbridge has a negligible effect. However, the Everest PhotoWorxx benchmark breaks the trend and confirms Everest's claim that this benchmark tests the CPU and memory subsystem. What's interesting is that overclocking the northbridge has a greater effect than overclocking the core frequency. As expected though, the combined overclock takes the lead and even appears to have a synergistic effect.

The gaming benchmarks tell a story similar to what we saw in the earlier sections of the review. At higher resolutions and quality settings, the video card is likely to hit a wall before the processor does. At lower resolutions though, we do see a significant effect from overclocking. Once again, the combined overclock is the performance leader, while the northbridge-only and cpu-only overclocks seem to vary depending on the game.

Hi There!

I would like to ask from you guys if which is better AMD Phenom II X4 965 BE or Intel® Core? i7-920. I am planning to assemble such high speed processors but I am confused about these two products.
Please send me your reply to my email which I provided.

Thanks & More Power,

R. Devocion, Jr.

sir, if you want performance, go for Core i7 920 though. It much faster than Phenomm II x4 965. but the phenom is much cheaper than core i7.

kevin, Are you sure man?
Phenom IIx4 965 in some aspects is better than Corei7 920,and core 2 Quad Q9650.
take a look at this processors comparison:
##anandtech.com/cpuchipsets/showdoc.aspx?i=3619

Phenom II 965 is cheap and with a very good performance.

Over all passmark rates both the i7 920 and Q9650 higher than the Phenom965 BE but they're comparable. Q9650 very comparable, i7 920 less comparable...however pricewise there's no comparison. Phenom 965BE is WAY less expensive! Phenom 965BE is a quadcore after all.
