HardOCP - 4.44GHz CPU -> VPU limited with a 425 MHz GPU

[pascal]

I believe an AMD processor at high clockspeeds would bottleneck the VPU even sooner than 4.4GHz.

First of all, this is irrelevant, besides which even with all that exotic cooling, the K7 is hitting architectural limits. I don't think it'll scale in clock all that much more. In any case, it's irrelevant because if you know when the P4 will begin to limit current day VPUs, you can compose a fairly good guess as to when this time will come around that P4's and K8's will shift the bottleneck onto the VPU.

Hi Saem

Some people are reporting running the Thoroughbred-B (.13 micron process with 9 metal layers) at 2.3GHz easy (almost 6x400)
I hope we will have a good surprise with Barton.

See this Anandtech CPU scalling with the GF4 Ti: http://www.anandtech.com/showdoc.html?i=1650&p=3

The CPU is the heart of the gamer´s rig. I prefer a very good CPU with a good GPU than a very good GPU with a good CPU.

The -B- cores are amazing, putting up crazy overclocks.

That's a rev. B 1700+. He hit 2320 with a 185 bus. I think he needs some higher quality ram to get to 200 MHz bus.

Right. There are people overclocking it to 2.166GHz (333MHz FSB) without ANY vcore change and without compromissing other system components. I call it overclock light

There is misbelief that all you need is a Thoroughbred B and soon you will get a 300MHz+ overclock.

The cooling, ram and other components play a great deal when overclocking and when you get a n00b asking questions like why wont my processor overclock so well it can be a bit of a, "durr", reaction from the community. Also when overclocking well one guy might get a good chip and the other guy a lemon from the same batch.

Couldn't have said it better myself.. and Saem even though the AMD processors are indeed not going to scale as much as the P4 design, we will see Barton chips at about 2.2GHz at least. That would be competitive to a P4 at 3.06GHz in many games - but we will see soon enough I hope.

Edit: In fact apart from a die process change I dont think the Athlon64's are designed to scale as well as the P4 architecture either.. hmmm but I could be completely wrong there.

I haven't kept up with CPU benchmarks of late, but I have trouble seeing this as the Athlon need more system bandwidth.

As for the Hammer, scalling looks to be an issue there as well, the two extra stages seem to have a fair bit of logic associated with them so I'm not sure how well it'll climb in clock rate. I wonder if AMD expected Hammer to be out a fair bit sooner and thus the design seems a little dated.
