Kuma Manifests into Athlon X2 7550, 7750
Industry sources reveal that AMD would be branding its Kuma dual-core processor as Athlon X2 7000 series. These processors are aimed to compete with Intel's Core 2 Duo E7000 series processors. Kuma continues to use the 65nm SOI fabrication process. The core sports 512 KB L2 cache per core, and a shared 2 MB L3 cache. Surprisingly, despite having sub-3.00 GHz clock speeds, the processors have rated TDP of 95W.
These processors use a broader 3600 MT/s HyperTransport interface, and feature DDR2 memory controllers that support the PC2-8500 (1066 MHz) standard. As for the models, the Athlon X2 7550 has a clock speed of 2.50 GHz, and an FSB multiplier of 12.5x. The Athlon X2 7750 comes with the clock speed of 2.70 GHz, and a FSB multiplier of 13.5x. Both processors are expected to be out by Q1 2009.
As for its 45nm successor, there are early indications that it would be succeeded by the Phenom X2 10000 series processors. Depending on the clock speeds, they would be branded as 10x00, with "x" deciding the model number. These would support PC3-10600 (DDR3-1333) memory and have lower TDP of 65W.

The 2.9 Ghz X2-5600 has a 65w TDP on the same 65nm process. Does the addition of L3 cache really increase TDP that much?
The 2.4 GHz Phenom X3-8750 has the same 95w TDP as the 2.5 Ghz X2-7550. That just doesn't add up unless these new X2s are binned processors that did not make the cut for X4 and X3 requirements.
Even that aside, if these are ridiculously cheap (55-60 USD) I still might get one, just for the fun of it.
You lose no performance having disabled cores.
However, if AMD were to just toss them out because all 4 cores didn't work, they would lose a ton of money. Money they don't have to lose.
Just be happy. These chips are gonna be cheap, have faster memory, an added L3 cache, and a 3600MT/s HyperTransport. Is it really worth complaining over cores that you'll never see?
i really do hope amd sort this out and start to compete with intel again. saying that, reports intels new nehalem might be all its cracked up to be either, so only time will tell.
a tad faster than what ? the e7** series? at stock i think not, amd needs to pull somthing out of the bag cause my confidence in them is dwindling by the day, and i dont think deneb is going to be there saving grace either :shadedshu
i did used to love amd, from my first thunderbird 800 and palamino 1900+ through to my 2500+, my x64 3200+ which i drove 180 miles to pick up onto my x2 3800+ and then suddenly from nowheer came this strange unknown creature named Core 2, and well the rest is history
