How to get P9500?

According to spec sheet "Intel® Core™2 Duo processor P9500
(2. 53GHz, 6MB L L 2, 1066MHz FSB, 25watt)" on T-series.

How to buy it?

Not sure what you mean by on T-series, which is 35W.

 

T-series = Thinkpad (denoted by a "T" in front of the model number, such as the OP's T61)

 

It was offered on the site at one point, but it was expensive. I think it was $200 more than the 130 MHz slower P8600 , and > $100 more than the comparable (except TDP) T9400. If you really want it though, I would just wait for it to appear on Lenovo's site.

 

I mean the thinkpad machine.

How is M4400? also how to get P9500 on M4400? I really like the RGB LED WUXGA option with many future-proof ports (e-sata, display) available.

Correct!

And it has 6MB cache? Thanks for answer.

 

I think it's pointless to buy a P9500 with a T500 or W500. Why? Because Lenovo does a good job cooling these machines - TDP means thermal design power, that's not to be confused with the actual power they draw (it's the heat they dissipate). Of course there is a corollarity, but it's much smaller than you think.

The P-series chips are selected T-series chips with somewhat higher quality, or there may be even T-series chips with the same quality at the same time (depending on demand and availability). They are otherwise the exact same as the T9400, no special power saving modes or whatsoever that makes them special.

There is just no point in buying it for the T500.

 

So it's not worth buying?

 

Maybe I'm missing something here but isn't virtually all the power drawn by the CPU eventually dissipated through heat? I mean, from an energy conservation point of view, the CPU drives some bus signals (both processors drive the same bus signals so this shouldn't be accounted for) and they might radiate electromagnetic waves (I don't see how a CPU can emit over 1W of electromagnetic waves unless it does it on purpose). However I would be really surprised if these factors accounted for more than 5% of the power consumption of the chip. That power drawn by switching transistors cannot go anywhere beside being dissipated though heat right?

Given the fact that the power supply of my laptop can only drive 56W among which I assume my laptop uses no more than 50W (I guess the folks at Lenovo gave themselves some margin), it appears reasonable to think that my CPU consumes no more than 25W which is pretty much its TDP...
