Turion 64 2X TL-56 or Turion 64 X2 TL-58?

I've stuck between 2 laptops, Acer Aspire 5520G and HP DV6565En, they both have the same specs, but one has TL-56 and other TL-58 (Both 1.8 GHz). And they have like 100$ differnce.
The question is simple: Which processor is better?

 

I'd lean towards the TL-58 since it's guaranteed to be one of the newer 65nm parts. It's not that big a deal, but still. I'd compare GPUs between the two machines, that's a much more important distinction.

 

A TL-58 should be 1.9Ghz and is built on 65nm chip, TL-56 is 1.8Ghz. 58 is better but not $100. 58 is 100Mhz faster 5% to 6%. That is the answer, I myself would save the $100.

 

brianstretch, GPUs are the same - GF 8400m GS.
Another difference is that HP has BT, and Acer has IR, but no BT. + HP looks much better, but I really don't care about design

And I found some info on this processors:
TL-56 1.8 GHz 2 x 512 KB L2 Cache, 33 Watt TDP, 65nm (31 Watt after May 07)
TL-58 1.9 GHz 2 x 512KB L2 Cache, 31 Watt TDP, 65nm

So, if they say that their Tl-58 is 1.8 Ghz, it may be 'underclocked'?

 

31 Watts after may because they switched to 65nm but does not mean you are not getting an old one.

 

im sure the TL-58 has a larger cache also im sure its 65nm though go for it

 

Yes all 58 65nm, No cache is the same 512 per core, AMD did not work w/the Devil to get huge L2.

 

say it in clear sentences please im tech-literate i just dont know what your saying

 

The most a Turion X2 has is 1024KB L2, 512KB per core. It is not shared. Devil comment was a dig at Intel.

 

oh i like it not being shared and along with the memory controllers turions are nearly(notice i said NEARLY) as good as the C2D

 

The L2 cache is not overly important in an AMD CPU like it is in an Intel CPU because AMD processors have the memory controller located right on the chip. The reason behind that is the CPU doesn't have to go far at all to get information from the memory; there's no real need to store a lot of information. Intel processors on the other hand have to get info from north bridge which takes longer. They have large caches so they don't have to run to the memory as often.

I'd agree with the previous comments that said that the TL-58 is definitely better if it's a 65nm part but it's not $100 better.

 

To add to Chaz comments above, The Turion X2 has double the L1 of a C2D and that is another difference in AMD vs. Intel strategy.
