AMD Athlon 64 X2 TK-53 1.7GHz versus AMD Turion X 2 Tl-52

I noticed this Athlon 64 Dual Core TK -53 at the store today. Is it new? What is the difference between this processor and the the Turion line or the Tl 52? I don't see any information on the AMD website. The price difference bewtween the laptops is about $100 with the TK-53 being cheaper. In the other hand I can spend the money to upgrade the RAM from 1 gb to 2 gb, which might help the overall performance. The guys at Circuit City had absolutely no idea what the difference was

 

Built on 65nm chip not 90nm like the Trinidad TL-52, 1.7Ghz instead of 1.6Ghz, but half the L2 cache 2X256 instead of 2X512. Extra RAM would work better than TL-52 w/1GB.

 

Lets say this is the name of an AMD processor AB-CD.

A: differentiates between single and dual core, M for single, T for dual
B: the electrical usage of the processor, the later in the alphabet, the less usage, thus L will be more efficient than K
CD: The speed rating of the processor, the larger, the faster.

Thus a TK-53 will be faster than a TL-52, but will have worse battery life.

Edit: Yay Wikipedia

 

Interesting could you link to that info. I have some confusion with what you say, my TL-52 31 mW the TL's above in the Trinidad (90nm) line are 34 mW. I believe the new TL's and TK (65nm) are 31 mW also, so I have doubts about your “power usage” comment. I think it is a naming convention, with the TL-50 (2X256 L2) not a problem “lower” # but with this giving higher number with ½ the L2? It is just a TL-50 100Mhz faster and I doubt faster than a TL-52 performance wise, real world sure about the same.

 

Lithus is correct. If you dig through the AMD website long enough it will give you the same answer as Lithius.

 

I think this is the link that will open our eyes to the mystery behind AMD's numbering and lettering system

Actually since the TK-53 is 65nm hence a new gen. it could be faster & more efficient.But, lets not revive old threads.
