News - AMD reveals more details on Bulldozer and Bobcat CPUs

[Jimbo75]

Dresdenboy found some benchmarks on BOINC for Sandy Bridge. It's not the "revolution" intel fans are hoping for.

I thought the focus for Sandy was power/heat rather than performance as they have that currently with the i7 really? (quite probably wrong though )

The server version is 50% faster than the previous top AMD server chip.

We don't know about overclockability, but no reason to think it's going to be bad.

We don't know either of those things. The k version chips are easy to overclock, and there are no performance figures so I'm not sure where you get the performance statement from.

well they said that the base clock was tied to the USB and all the other clocks like this, so raising that will corrupt all the peripherals connected to it. And the K series is the ones with unlocked multiplier,and they are expensive

From that link:
"This means, the tested mobile Sandy Bridge processor was as fast as a Core i7-975 Extreme" What revolution are Intel fans looking for that's faster than that??!

I would be surprised if final silicon performance reflects those early figures. And which chip was that - the bottom end ultra-low power variant, or the top-end enthusiast edition?

They're not even out yet so I'm not sure how you can also assert they are expensive. Base clock tied to USB? Doesn't make sense to me. I'm pretty sure that the enthusiast level chips will be nicely overclockable.

By using a design that combines discrete and shared components, the company hopes to create a chip that increases performance without having redundant and underutilised parts of the core.

Is AMD finally implementing hyperthreading?

Is AMD finally implementing hyperthreading?

Absolutely not. What they mean is that there are several components that can be shared between two cores, like the fetcher, while others like the integer pipelines are discrete and duplicated between two cores.

I'm not really keen on this focus on Integer power... bad news for gamers that's for sure, as in general, we need more FP power.

I wonder if they will somehow leverage the GPU to do additional FP work should the need arise?

[kalniel]

Eventually, that's the plan for fusion. But Bulldozer will still be much better for gaming that previous AMD chips.

apparently these are going to be on AM3+
