AMD Overdrive...but for Phenom

I think why way AMD have made a native quad (4 seperate but linked cores) this is why AMD can do this.

Intels current quads are 2x C2D basicly.

I dont know about future intel quads.

As far as i am aware, reading the forums, the new Intel processors (1333Mhz ones) will be native quad core, so be similar to the AMD architecture (as u mention above)
 
penryn is a die shrink and minor update to conroe, so still 2x2. Its nehalem which is going to be native quad core and include the memory controller iirc

Great bit of kit something similar from Intel would be nice.

Not gonna happen till at least Nehlem i wouldn't expect.
The only reason this is possible is because Phenom utilises split power planes to reduce energy consumption.
I bet that this feature is only available for users with AM2+ motherboards as well. If not, then i dunno how it works.


As for those asking what the benefits of this are, it is simple. OVERCLOCKING. Being able to clock each core to different levels means you will be able to achieve the highest overclock possible. On old AMD and Intel cpus, the overclock is limited by the weakest core. This negates the problem and allows each core to go as fast as possible. Awesome bit of software for hardcore overclockers.

CnQ was always gonna be available for Phenom :) The split power planes means that single threaded software which only uses 1 core will let he other 3 cores shut down completely, dramatically reducing power consumption.
 
Ah right, its the Nehalem that will be native, thought the penryn were going to be.

No matter, thanks for pointing that out :D

I'll be very surprised if anyone bar the odd person can get a better overclock using this method. Given that Phenom is a single chunk of silicon from the same point of the wafer the quality will be very similar across all cores. The variation in clockabilty will likely be significantly less than 100MHz between all 4 cores.

So why won't people be able to get that 100MHz? Well with an already overclocked FSB (say 250-300MHz) even with the half multi's the next notch up will yeild a fair bit more than 100MHz. Plus to make use of the extra multi, you're going to have to drop the rest of the cores multipliers, meaning you'll need to increase the FSB even higher to compensate.
