News - AMD FX-Series Turbo Core speeds also disclosed?

Remaining bits of the puzzle slotting into place.

Read more.

Very nice.

Hopefully this is a result of them keeping their clockspeed know-how from later Phenoms, where they optimised the process very well, and have transferred this to the new process, rather than them going for a lower IPC/higher clock design.

Last but not least of the 8-core flavours, the FX-8100

Yes it is!

[Jasp]

Thought their was supposed to be a 8170 from older slides?

that will probably come shortly after the first wave

That's actually very impressive for 8 physical cores - Comparable with the Intel numebrs that are out there anyway, which can only be good for us consumers.

Now.... Lets see how they fold...

Ooooh just as I was completely losing faith in AMD... Look forward to seeing the benches

I'm confused - how did they apparently manage to do a 125W and a 95W version of the 8120? Unless the latter is downclocked somehow...
(EDIT: Thanks to Kalneil for the subsequent "for Dummies" explanation - given in the next post - to that comment above. Thanks duly sent!)

I'm running a 1090T at the moment and have been amazed how fast it is for the stuff I do. So the idea of maybe getting 800MHz more per core, two more cores, more cache and simultaneously drawing 30W less is a big attraction to me.

That big 8-way with a good slab o' memory would make a superb VM host...

All chips display different levels of leakage. The more leaky the chip, the more volts it requires to perform at a given speed. If you have a good chip you can either crank up the speed within a given voltage, or perform the same speed for lower volts. A less good chip might only be able to do the lower speed with higher volts.

So for the same speed you can have a variety of quality of chips - the best ones will do it for the lower power.. however at the start all of these might go into your top range chip. Later on your chip production quality might improve and you can start offering lower wattage chips. Alternatively some people might pay a premium for lower power, or finally some people might want to cap the power a CPU uses for thermal reasons.

These chips have the ability to cap TDP in software/firmware.

AMD had 95W and 125W versions of the Phenom II X4 945 and Phenom II X6 1055T.
