Is your AMD64 X2 65nm or 90nm?

I just placed an order of dv6000z on HP's website. For the processor I chose "AMD Turion 64 X2 TL-56 1.8GHz", because I thought all TL-56 are 65nm SOI.

Later I found there are actually two versions of TL-56, on AMD's website:

65nm: http://products.amd.com/en-us/NotebookCPUDetail.aspx?id=5
90nm: http://products.amd.com/en-us/NotebookCPUDetail.aspx?id=8

The major difference is that 65nm should be cooler than 90nm. But this is not clearly labelled in HP's website.

So I want to ask everyone who already have their dv6000z, what's the SOI of your AMD64 X2?

It will be sad it is 90nm.

Thanks a lot!

 

This is interesting...I had thought that AMD had not reached the 65nm mark yet. So whats the big difference now between it and C2D? Cache size for each core perhaps? And how much does that really matter?

 

AMD has been shipping 65nm CPUs for several months now. Currently chips are just a die shrink of the previous 90nm design. Their new core design starts with server CPUs next month. I'm not sure when it will be available for notebooks, might not be this year.

AMD CPUs don't need the massive L2 caches that Intel chips use because they have integrated memory controllers and aren't hobbled by the old-fashioned frontside bus architecture that Intel still uses.

 

Viz. L2 caches, there is also a basic design difference that makes a straight-forward comparison apples-n-oranges; namely, on the Intel C2D chips both cores share the L2 cache whereas on the AMD 64x2 chips, each core has its own private L2 cache. Basically, you're correct in that the AMD chips do not need an L2 cache the size of the Intel C2D shared cache because of the design differences.

If anyone is really, really curious (or bored), a very basic discussion of the differences in the Intel and AMD architectures, and my driveling on the subject , can be found here: http://forum.notebookreview.com/showthread.php?t=147332

 

Have anyone bought HP Pavilion laptop with a AMD Turion processor recently that the processor is 90nm?

 

Just got my dv6000z. Luckily it's 65nm. Very cool!

 

how do u find out ?

 

CPU-Z will tell you.
