(Dell Inspiron 1420) Big difference? T7300 and T7500

hi guys, im planning to order a dell inspiron 1420 this coming monday in hongkong. but i just wana ask, is there a big difference/improvement between T7300(2.0GHz, 4MB L2 Cache, 800 MHz FSB) and T7500 (2.2GHz, 4MB L2 Cache, 800 MHz FSB)? Will these specs change/improve the performance of the laptop dramatically? 3dmarks, speed, etc. Also the 160gb (5400rpm) and 160gb (7200rpm), is there a big improvement if i will choose the 7200?

Additional questions:

how about the difference between T7300 (2.0GHz, 4MB L2 Cache, 800 MHz FSB) and the T7250 (2.0GHz, 2MB L2 Cache, 800 MHz FSB)? almost no difference? how about the screens resolution? 14.1" UltraSharpTM Widescreen WXGA+ ( 1440x900) TFT Display with TrueLife(TM) and 14.1" Widescreen WXGA ( 1280x800) TFT Display with TrueLife(TM)?

 

The .2 ghz difference won't matter that much IMO. The faster HDD might be worth it though many would say to buy it separately and add it in yourself

 

I'm in the sane position. What would be an estimate in % difference between the two?

 

hehe, hope someone will help us^^

 

2.0 vs 2.2 - no difference, same cpu
5400 vs 7200 - no difference
2.2 + 7200 - 10% difference but is it worth it - no

 

There will be no difference between the two unless you run extremly CPU intensive applications. Even the T7100 gives the same performance in every day use compared to the T7300 and T7500.

 

For CPU intensive work (Audio/Video encoding. Rendering, simulations etc..) difference is proportional to clock speed. For general computing and games you’ll hardly notice anything.

 

i see. thanks guys. how about the difference between T7300 (2.0GHz, 4MB L2 Cache, 800 MHz FSB) and the T7250 (2.0GHz, 2MB L2 Cache, 800 MHz FSB)? almost no difference? how about the screens resolution? 14.1" UltraSharpTM Widescreen WXGA+ ( 1440x900) TFT Display with TrueLife(TM) and 14.1" Widescreen WXGA ( 1280x800) TFT Display with TrueLife(TM)?

 

Again, CPU speed won't matter much if all you are looking for is internet browsing and other light work, which is what most notebooks are made for.

The screen resolution is a different story.

The higher the resolution, the more you'll fit in your screen. Less scrolling when reading or browsing, but the text will look smaller as you go higher in terms of resolution.

 

Hey guys, I'd like to join in on this. I'm looking at the same questions for a vostro unit. One thing I'm curious about though, will a T7300 with 4MB chache run hotter than say a T7100 with 2MB chache? And if so, how much more(significantly)? I've heard that more onborard memory will produce more heat.

 

Hi guys ,
how about the difference between T5250 (1.5 GHz, 2MB L2 Cache, 667 MHz FSB) and the T7250 (2.0GHz, 2MB L2 Cache, 800 MHz FSB)? almost no difference? or is it worth the difference of 170 US Dollar ??

 

up! answers please^^

 

my T7500 runs cooler than T7300 and T7300 is cooler than T5470. anyone has T7700 or T7800 max temps data on 1420/1400?

 

My original 1420 was T7100, replacement is T7500. Not much warmer if any. Not much performance improvement beside video editing.

 

i see. cant wait to have mine.

 

The Intel Core architecture scales well with clocks. So with a 0.2 ghz increase = 10%, you are looking at a *max* of 10% performance increases (application wise). On Average it would likely be a 5% increase in performance. The 2mb L2 Cache also adds about 5% increase in performance (There was an Anandtech.com article that specifically addressed this question).

From the T7250 -> T7500, your looking at an average of 10% increase in performance. I would say for the most part, probably even more.

As we increase from 2.2 - 2.4 and 2.4 -> 2.6 and 2.6 -> 2.8, you can do the math, the % increase in clocks decrease each time. Diminishing returns in effect. The best speed bump is probably the 1.8 -> 2.0, which comes with 11.11% increase with speed and a 5% increase from the L2 Cache = average of 11%.

 

Please don't just talk and spread around false information.

 

so whats the true information?

 

so whats better a t7250 or a t7200 ,

t7200 -----------2.0ghz ------------667fsb ---------4mb cache
t7250 -----------2.0ghz ------------800fsb ---------2mb cache

wtih 667 mhz ram
