That's interesting. A lower tdp and a higher maximum temperature? One wonders what they changed. Are these chips that have exceptionally low leakage (essentially the opposite of their TWKR CPUs)?

It definitely appears AMD's 45nm process is maturing and working out great. Much better than their 65nm process.

No, it just means they can withstand higher temperatures. This could actually be useful for HTPCs who want low noise, although those users will probably be fine with a much cheaper dual core.

Um . . . what lead you to conclude that the 95W x4-945 isn't just a bunch of 955s binned for low gate leakage? If this is merely a maturation of AMD's/Globalfoundry's 45nm process then great, but if they're just binned based on gate leakage, I have to wonder how well they'll OC.

Not that anyone looking for a HTPC CPU would care about that.

i highly doubt this is a huge improvement over the 125W ones.

125W tdp doesn't mean it uses 125W. it just means it uses somewhere below 125W. Its more than likely the first batches needed a little more voltage to run at rated speed for an entire batch. maybe it used up 97W at a theoretical max load (which never happens, if you know how the AMD TDP is setup differently than intel) with that slightly higher voltage and these new ones use 94W.

Maybe it used up 124W!

Just joking.

But for the comment:

these new ones use 94W

you are probably correct!

Yes, propably you and hans007 were right about the small difference in actual TDP (like I said I was only joking about the 124W comment)

The only reason I even did this topic, was to offer something positive to say about AMD's CPU lineup, since first earth will stop moving, before I buy a CPU above 65 TDP (here in Greece we pay 0,13? (inc. VAT) per KW, and also, I am extremely eco friendly)

guess you'll have to wait for the athlon II x4 630 next month

Intel did the same thing with the q6600. The B3 stepping had a max temp of like 62 and a higher tdp (i forget what it was 135 maybe). The G0 had a max temperature of like 72 and a lower tdp.

I'm sure it happens with all the chips that get new steppings that's just the one example I'm familiar with cause I have that chip

If i wanted this kind of performance i would have bought a Phenom II X4 905e already (905e should be a little bit faster overall +20% / -10% ).

Of cource even if i wanted this kind of performance i wouldn't choose the 905e becauce its price is not good.

What i would actually buy, is something like a 3Ghz Phenom II X4 6XXe series, if i could find it in a good price, but this is not going to happen anyway.

I will stop here, becauce after all, my original intetion was to make a positive topic about AMD.

A good point. There have been numerous instances of stepping revisions reducing tdp either officially or unofficially. I merely wondered about the x4-945 (pardon the 955 typo in one of my above posts) due to the existence of the TWKR edition CPUs and how they apparently binned for those chips.

Any maturation of AMD's 45nm process is a good thing, and maybe we'll see better overclocks out of these new chips.
