If the new revision needs less power to hit the same clock speeds as the preceding Phenom II X4 965 BE, then it follows that there might be a little more overclocking headroom with which to play.
To see if this was the case, we tried a simple test: we would increase the Phenom II X4 965's unlocked CPU multiplier using the AMD Overdrive tool. We kept increasing the multiplier in one-half steps until the overclock would crash the system. After it crashed, we would repeat the process, but this time we would increase CPU voltage to 1.5V from stock. We did this test using both revisions of the CPUs, and here are the results:
The new C3 revision Phenom II X4 965 sample we have demonstrated a promising 200 MHz increase in overclockability under identical conditions versus the older C2 sample. Now, we should stress that no two CPUs are identical and there will be discrepancies in overclocking headroom amongst models with identical stepping, so this doesn't necessarily guarantee that your results will mirror ours.
Having said that, a 200 MHz increase at identical voltage certainly seems promising.
its a bigger change than say the step from C0 to D0 with the 1366 I7's
Its not like im a normal AMD fanboy, i just dont like monopolistisk tendenses, so as a builder i do have to know when i can tell u get the best rig with AMD or do u have to go to Intel.
I still hope Toms and preferabel Cleave comes with a review when a cpu bottelneck 5850 and 5870 at best grapic settings. Hilbert shows us that the AThlon II 435 do bottelneck a 5870, but since 5850 is round 15% slower than 5870, even the athlII 435 at stock should be close to take advantage of a radeon 5850.
Intels R&d last yr was as big as AMDs total sale, take in account that thay also fight Nvidia, so then u maybe understand why AMD is not best. If AMD drops farther down, what are we nerds left with, the answear should be clear to anyone that can think, we are left with only Intel.
I do build riggs, guess round 100 over 18 yr, for friends and stuff, i do refuse to build Intel riggs, why ?, becouse of the marked situation, we lost cyris as a cpu vendor, if we loose AMD to, then my fellow nerds, we are in troubel. I do however never recomend an AMD built if Intel is clearly supperiour, therefor we builder need to know the limits. AS toms has stated in severual test, AMD is good at budget riggs, but how far up can an Athl II 435, an Phii 720 suppurt a grapfic card, well even the phii955 is dirt cheap here.
Still, that doesn't solve my issue as another potential builder: since AMD and Intel now make equally well performing CPU's (for gaming purposes, that is), is there a reason not to pick the cheaper AMD? Higher power consumption, or less well performing motherboards, or something along these lines?
Try harder next time.
for speculation , in apps/games that really use 4 cores (x264/gta4), it would not be up to phenom II X4's and even Phenom II X3's .
in apps/games that dont use more than two cores , it would take out every amd offering . although it would be "in line' upgrade for anyone with a core 2 duo , quads are getting more and more important . i also hope that the rumors of very high clock speeds/practical everyday use overclockability are true . lets all wait now !
