Which CPU would you put in your laptop, provided you had a choice between those 3 and price would not matter; but power consuption, speed and heat

T7200 - 2.00GHz, least heat, most battery
T7400 - 2.16GHz, compromise between two
T7600 - 2.33GHz, more heat, less battery


Not planning on using games.

Any personal coments?

Are you intentionally omitting cost as a variable?

Edit: Oh, indeed you are. Sorry.

I chose the T7200. If you run a lot of CPU intensive applications and need the most performance possible then go with the T7400 or T7600.

I'm not sure you'll draw any meaningful conclusions from this poll. Everyone's requirements will be different, and all you will be getting is different people's perspectives, which may or may not apply to your own. If you place a premium on battery life, then go for the T7200. If you want the absolute highest CPU performance, then go for the T7600. But really, the difference between a 2.00 GHz part and a 2.33 GHz part may not be all the significant in the real world. The biggest differentiator would then be cost (and availability), but you told us to ignore that factor.

So I choose all three.

See, now I've skewed your results, because I voted with cost in mind. I choose the T7200 because it offers the best bang-for-buck. But if I had been given both CPUs for the same cost, I would choose the T7600, because I can more easily and reliably slow down a CPU than speed it up.

I voted for the wrong one, too. If money is no object absolutely choose the t7600. It will NOT produce more heat then the T7200, thanks to intel's speedstep and voltage control... both processers will spend most of their life at the same speed and voltage level.

I believe that all three processors will probably throttle back clock speed under power saving modes to the same level... thus will probably have similar power consumption characteristics. If someone would like to correct me if I'm wrong, feel free to do so. So... the only issue then is which has the highest performance in a non-power saving setting. Thus you would choose a T7600

T7200 - 2.00GHz, least heat, most battery,less expensive,almost same performance, 4mb cache!

T7200 2.00GHz works great for me.

t7600 for me, I like to have the most amount of power, you can scale it down using power mgt as mentioned before, but you can also go full throttle

mine also works great!!!

And it has like " little of everything" least heat , most battery life , consuption and most important Speed!!!

also keep in mind about the ram and HD speed too which it has a lot to do if you go for the 7600 for example.

these cpus come out of the same manufacturing line and graded based level of performance / stability at a given condition.

the t7600 should be identical to the t7200 just able to operate at a higher frequency with more stability.

if price was same, then no reason not to use the t7600 as you can underclock/ undervolt with software to operate at t7200 levels...

with that said, in the real world, the t7600 is more than twice the price of a t7200...

unless the t7600 prices become more affordable, the t7200 is definately the better choice.

You don't need any tools, the 7600 throttles down to 1ghz at 0,95V in battery optimized Mode as the 7200 does, there ist absolutely no difference between them.

Its kinda funny, but I think probably the biggest draw on your battery are probably: (for the t60p)

1) The GPU, this is based on the fact that it operates at a much higher temperature than the CPU, thus, logically, it draws a fair amount of power.
2) The screen: depends on your screen size (smaller is better in my opinion)
3) The 7200 RPM hard drive*


*Does it slow down when it is unplugged?

Hello Killigrew,
yes you are correct. i wasn't explicit in my post. what i meant was that you can block out the higher frequency settings with software and make the t7600 behave exactly like the t7200.

also agree with abu_sme, regarding power draining devices...

I would have gotten the T7600, but at the time, it wasn't available in the configuration I wanted... however, I am completely satisfied with my T7200. It's really really fast, and there is virtually no sluggishness, even when running several Firefox windows and ripping CDs and stuff.

T7200, I'll have all the CPU intensive jobs running on my desktop.

T7600, if money is not an issue - there is negligible difference in the battery power due to the processor. Main culprits are the GPU and LCD.

Hi folks

Please don't bash me from resurrecting this thread from the after-life...

But I was just wondering... I've recently upgraded my T60p to a T7200 which seems to be rock stable @ 0.95v using RM Clock at all speeds. So my question is, would a 7600 @ full throttle @ 0.95v (granted it would work stable at that voltage) consume more power than the T7200 at full throttle at the same voltage? Which is to say, is voltage the only factor that determines power consumption / heat or does speed also affect it? Sorry if it's a n00b question

There's your answer, been there since Mon Apr 16, 2007 6:52 am

well... that's only telling us that at the lowest coefficient it's exactly the same, not at the highest... and that's what I wanted to know...
