T6600 vs P7450 ($50 difference)

I am configuring a HP laptop and need help deciding between the T6600 and the P7450.

The P7450 is $50 more, but I understand it runs cooler, uses less power, has 3mb L2 cache vs 2mb, and 1066MHz FSB vs 800MHz FSB.
The T6600 has .07Ghz higher than P7450 and I have heard has better performance.

Which would be a better pick.

Or should I spend $100 more for P7550 or $200 for P8700.

Thanks.

 

I'd say yes to the P7450, and no to the P7550 or P8700. You're getting the higher clock, faster bus, bigger cache, and lower TDP going from the T6600 to the P7450, but the P7550 and P8700 are effectively just clock speed hikes from that point on (and real small ones at that) and definitely not worth $50 and $100 respectively. You get Intel VT support on the P8700, but if you needed that, you probably wouldn't be looking at the P7000 series in the first place?

 

You won't notice any difference in performance between T6600 and P7450.

And I expect that when you undervolt you won't notice any difference in heat and battery life.

 

Undervolting only helps when you're pushing the CPU. Besides, you can also undervolt the P7450.

I would go for the P7450. It's going to be a bit cooler and a bit faster, along with providing slightly better battery life.

 

Some people have argued that through undervolting the difference between T and P becomes minimal. I tend to believe them.

And I don't necessarily believe Intel's TDP rating. Both CPUs are the same 45nm cores on about the same clock. Battery life numbers for the new Sony SR with T6400 have confirmed my beliefs.

I can understand that people believe the P7350 will give more battery life and less heat than T6400, but I'd like to see hard numbers before I believe it. TDP isn't convincing me.

If someone can give me real life numbers of T6400/T6500 vs. P7350/P7450 I'd appreciate it.

 

I believe that the T6600 would be a better choice. [i chose base on item #2 below ]


I am also choosing between T6600 and P7350 for the laptop that I will buy.
So I searched and this is what I just found:

1.) You can check the websites below that showed that
- what we are weighing is the 0.2 Ghz (for the T6600) and the 1Mb L2 (for the P7350)
>> if you are after the performance ( 0.2Ghz or 1Mb ??? ) continue reading item #2 ("What about performance...") below.
>> if you are after thermal heat dissipation, i believe you should opt for P7350. I'm just not certain exactly what the 25W vs 35W difference can do (possibly battery performance??? possible... but upto what extent exactly...?)
- one trivia to note also from this website is that it also explained that the internal frequency for P7350 is 1.9988Ghz (1066Mhz / 4 * 7.5) while for the T6600 is 2.20Ghz (800Mhz / 4 * 11) which can be attributed to the clock multiplier (7.5 for P7350 and 11 for T6600). This is the one that caused the 0.2Ghz difference in favor of T6600. According to them, "Clock multipliers on many modern processors are fixed - it is usually not possible to change them."

Here are the link for the CPU details:

P7350

2.) But what about their performance? This another website showed that T6600 is a better choice than P7350 in terms of PassMark - CPU Mark (although i'm not sure what it actually measures... all i know is that the higher the PassMark the better. I also assumed that this also considered the L2 cache in the cpu performance.)

http://www.cpubenchmark.net/cpu_list.php

In that website,
T6600 is ranked as 169th while
P7350 is ranked as 197th
with this i believe that T6600 is better between the two options (in terms of cpu perf).

You can also use this if you are still considering your other cpu options.

i hope this helped

 

LOL that cpubenchmark website is inaccurate....

 

maybe get some proof before you state things like that

http://www.notebookcheck.net/Mobile-Processors-Benchmarklist.2436.0.html

not inaccurate as the p7350 is clocked lower than a t6600, also if im not mistaken the P series is just a shrunken T series that has a faster fsb and lower wattage. So if it was running DDR2 ram the CPU clock would determine the speed. The T6600 would run hotter

This makes sense in synthetic benchmarks as the P7350 is clocked at 2 ghz, the T6600 is at 2.2 ghz

however in real world use i would go for the p series, lower heat, more l2 cache means better real world performance

 

Well there are a lot of errors in Passmark's CPU list so he has got a point.

I'm not saying the numbers for T6600 or P7350 are wrong, I don't have enough information to judge that.
