Overclocking
If the new revision needs less power to get to the same clock speeds as the previous Phenom II X4 965, then it follows that there might be a little more overclocking headroom to play with.
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 1.5 Volts 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 over the older C2 sample. Now, we should stress that no two CPUs are identical and there will be massive discrepancies in overclocking headroom amongst models with identical stepping, so this proves nothing.
Having said that, a 200 MHz increase at identical voltage certainly seems promising, doesn't it?

I think your article raises an important point about the reasons why people aren't jumping on the Intel bandwagon, because it's not all about performance.
I don't think the AMD products perform badly, either. Considering the Athlon II architecture's retail price plus the fact it's a generation behind the i7 range, I think it does quite well. Couple it with a suitable, low-cost motherboard with stable, fast blue-ray and game acceleration, and it starts to look rosy. Contemplate the ability to use some of your old bits lying around and it looks very hard to turn it down.
And looking to the future..is it wise to follow Intel's path, considering the performance gains to be had from GPGPU technology? I don't think it is..I think it's akin to putting all of one's eggs in one basket, so to speak. On the GPGPU front, who is in a better position to cater for future needs: Intel or AMD? What kind of GPU technology could Intel offer, should companies like nVidia stop giving their support?
AMD is still competing on longevity and price, and the performance is so good for general consumer use..does it matter whether i7 is faster? You go with AMD you know you can upgrade and replace with relative ease..you go with Intel and it's like worrying about whether or not DRDRAM is all it's cracked up to be; the clients I built Intel rigs resented the fact they needed new sockets, memory etc to get better performance.
More than one way to skin a cat, I think AMD knows this, and Intel doesn't care much because it's still basing it's products purely on prestige status and brand loyalty.
Budget or home computing = AMD
Premium or professional computing = Intel
Simple, reliable formula and if AMD actually advertised this fact they'd make a killing - you don't need to outperform to outcompete.
Office or cubicle computing? AMD probably, or the new Atoms.
The article makes a valid point, I upgrade usually upgrade my computer for €2-400 two times every year (x-mas and summer vacation).

The recent upgrade history has been.
summer 09: new mobo €100, new fans €40, new external harddrive €130
Xmas 08: new router €100, 8gb of memory €140
summer 08: new cpu €140, cpucoling €80, harddrive €100, chassi €80, monitor €200
If I expect to use a unit for twice the time i spend twice the amount on it. Routers are one thing where it's worth spending on, the same goes for chassi, PSU monitor, keyboard, mouse etc. If I going to use a motherboard for a year I buy asrock, gigabit. If I expect to have two or more asus is the shit
AMD's found a niche: cheap yet powerful, quad-core computing coupled with a realisable motherboard technology. If Core 2 Quad is good enough for you, then so is Athlon II x4..and at a significantly lower price.
What can Intel do? Sure, it can match performance..but if matches this price (which I think is a bargain), it's going to undercut it's own products by a huge margin.
Quad-Core Considerations..
AMD Athlon II x 4 620 (2.66GHz, 95W) ... £72
Intel Core 2 Quad (2.66GHz, 95W) ... £135
Intel i5 750 (2.66GHz, 95W) ... £152
..factor into that, the possibility you may be using an AMD-based motherboard already (say, AM2+ or AM3). You've just significantly lowered your upgrade costs and in a lot of cases you won't even need a new PSU.
In this instance..would you be willing to reformat and re-install everything for the sake of a Core 2 Quad, when you can get similar (or better performance)? I wouldn't. I wouldn't touch i5 or i7, either (the latter only if I was running CAD). If you wanted to transcode video using NVIDIA CUDA or ATI Stream you'd simply use the money you saved and get a fast card and maybe a new PSU. Also maybe a bigger, faster hard drive. For a machine that is probably going to spend a lot of it's time just browsing or doing reports..I really can't see a weakness at all.
"you don't need to out-perform to outcompete." I agree..AMD couldn't hit Intel head-on so, they flanked them..and I reckon it's having quite an impact. I think the saving grace was not only the refined Athlon core (producing the Athlon II architecture), but the fact a lot of things were already integrated into the CPU logic, such as Hyper-Transport and memory controller. It was a good design from the start, a better one by design that borrowed principles from much bigger, faster technology and as a result it has scaled incredibly well across multiple cores. Even today the Athlon architecture is proving it's worth so hopefully if history does repeat itself, when AMD brings out something next-gen it will be just that. It isn't promising the world with these little Athlon II chips, either, which I think is notable.
Bravooooooooooooooooooooooooo AMD - ATI Radeon . Love it You Guys ! GG

I notice they didn't throw in any Core 2 Quad's in that review..I wonder why:
Well what would one expect from a chip that's a generation ahead? The Phenom II is good to go against Core 2 Quad..and then some. So, if these tests that seem to be oh-so eager to demonstrate the greatness of Intel, are eager to try and downgrade the performance characteristic of Phenom II then by default they're also saying that Core 2 Quad is as bad..most people don't own Core-i5, or i7.
The Core2 architecture is probably a little faster than the Phenom II/Athlon II despite not having the MMU on-die but a lot of benchmarks do seem to be tailored towards Intel, plus AMD doesn't currently have SSE4 on any of their processors (ignore SSE4a). Also, the cache system is radically different; AMD goes for exclusive whilst Intel doesn't. Could it be that continuing to go exclusive is harming AMD, or are they simply trying to maximise the cache they have for the heaviest multitasking environments?
For god's sake, increase the htt speed on these processors. Every single review of an AMD BE i've just seen multi increases. You people are "professionals" and yet you dont do such a basic thing. You can squeeze much more performance out of theseif you overclock them properly.
AMD no longer in South africa....FAIL...
all I can say is , I have a £45.00 AMD x2 chip that runs lovely at 3.3 ghz and it never gets bogged down , the whole system cost's under £270.00 ...beat that intel
not sure the fusion idea for integrated on-die cpu and graphics is a good plan - typically i'll upgrade a graphics card 2-3 times in a cpu cycle which means the target audience is going to be casual home users and corporate environments - two areas intel has a pretty tight stranglehold on thanks to advertising, perception of quality (and underhand exlcusivity deals with major suppliers (dell, hp etc))
today, i get my new C3 965BE, replacing my x2 7750BE. im hoping the increase in performance im expecting lives up to my expectations!
fingers crossed!
