Athlon 2650e & X2 3250e

The single-core 2650e (Lima core) is clocked at 1.6GHz with a TDP of 15 watts, and the dual-core 3250e Brisbane is clocked at 1.5GHz with a TDP of 22 watts.

I think these results can be obtained by undervolting and underclocking a regular LE/X2 CPU as well but I thought I'd mention the CPUs anyway.

I think these results can be obtained by undervolting and underclocking a regular LE/X2 CPU as well but I thought I'd mention the CPUs anyway.

If you underclock a 45 W 4850e to 1.5 GHz and keep the Vcore at 1.2 V you'll have a TDP = 27 W.
If you also undervolt it to 1.08 V you'll get 22 W.
This is all theoretial, of course, but I think it's possible.
Underclock 40 % and still only undervolt 10 % with these CPU's will most likely work.
The situation is similar to when the famous 35 W 3800+ showed up, people went crazy (not saying that you are ) about this overpriced and next to nonexsitent CPU,
while they totally forgot the cheaper yet faster and more available 65 W 4600+. The Vcore difference was bigger though.

I'd never buy any of those new parts, because you'd never know if you need that extra GHz in the future.
They will most likely not be any cheaper than the 4850e anyway.
But like your link says, they're meant for small systems built by OEM's, and they don't underclock or undervolt the CPU's.

Yes, that was what I assumed. I bet the 4850e is cheaper and more available as well. By the way, is this TDP calculator still valid, even when using multi-core CPUs? According to that, my Sempron (2 GHz, 0.936 V) has a TDP of 22 W, not too bad.

No, I'm not really crazy about these CPUs, I'm somewhat into lowering my system's power consumption though (thus my nickname ) but I'd rather use a "normal" CPU and see how low that one goes.

That calculator is valid, I don't think that the number of cores makes any difference.

A spanish web has a AMD roadmap picture, too.

According to this tdp calculator existing X2 4850e Brisbane has TDP 22W with 1500mhz and 1.075V and existing X1 3800+ ee Lima would be TDP 15W with 1600mhz and 0.85V if it was stable, although I heard this old cpus had even lower max power than the stated TDP, so it's possible that a higher voltage will be sufficient to reach real 15W with this Lima.

Just released in europe is a new 45w CPU, the Athlon x2 5050e (2.6GHz)
Price is around 75€ and the 4850 dropped to 55€

And also a new 6500+ BE but this will have be 95 W with only 2.3 Ghz
(only saw one shop that listed this CPU and price was 109€)

That is a dual-core K10 (a "dual-core Phenom" if you want to say so) but still, the high TDP is odd.

Especially since that's the same TDP as for the four core, 2.4 GHz 9750.

I'm really interested how will the new 5050e compare to the existing 4850e (and similar CPUs) at the same voltage and frequency settings...
