T9600 or i7 720QM????

Hi,

Simple question; if all else can be considered equal (6 to 8GB RAM memory, decent graphics card, etc)... which of these processors would be the fastest/most dynamic for photo/image editing (RAW, JPEG, etc), and if the differences are minimal is the i7 set up worth the extra cost???

I thank you!

Niffy

 

yesyesyes 10 char

 

Ummmm... pardon?

 

He meant to say that yes the i7 will be better than the t9600. Much much better.

 

Yes, it's better and it will be a lot smoother to photo edit with i7. (I assume you use PhotoShop)

 

Yep, Photoshop it is. Will 6GB RAM be enough do you think???

 

It should be fine, just remember you need a 64bit OS

 

the i7 is cheaper if youorder from Dell but I dont think it is much faster than T9600 or better core 2 due for photoshopping or ACR stuff, but for video encording, the i7 is quite a bit faster.

I think the i7-820 is a good deal , much cheaper than the 920 and faster than the 720 with 8mb L2C.

 

Absolutely get the quad. The dual will lag on photo editing work.

 

The core i7 Q720QM is on par with the current QX9300.
Some extra info is found on the link on my sig.

 

The 820 is only 133mhz faster than the 720 yet is according to Dell Canada's website an extra $300 not very cost effective.

A 720 is going to mop the floor with the T9600

 

Under base clocks, yes, but the 820's Turbo Mode has 2/2/8/10 overclocks vs the 1/1/6/9 overclocks for the 720.

The 720 thus won't clock quite as high as the T9600 on 2 cores, but the difference should be more than made up for by the newer architecture. The 820 should both clock faster and run faster.

 

HDD speed will lag him more than CPU speed.

beware the scratch disk on the same drive as the OS...

 

I disagree with you Judicator. The i7-Q720QM performs extremely well. On dual cored tasks, it uses one core running at 3.06GHz, thanks to TB and HT together, easily beating the T9600, and if you disable HT running 2 cores plus the TB gives you a 2.80GHz speed.

Refer to the link in my signature for more info.

 

What's to disagree with? 6x133 = 798 MHz boost, added to the 1600 MHz base frequency = 2398 MHz on 2 cores, compared to the T9600's 2800 MHz clock. I think the newer architecture should make up for the 400-odd MHz difference, though, and I do admit to forgetting about HT.

Your numbers seem to fit the 820QM... are you sure you don't have the 2 processors confused?

 

Core i7 owns any core 2 duo... so yes core i7-720 and not to mention its a quad!!

 

Doesn't HT only work with software designed to take advantage of it? and would 6GB DDR3 RAM outperform 8GB DDR2????

 

8GB > 6GB period. Doesn't matter if it's DDR3 or DDR2 in any real world applications.

 

You can't assume it that way. Because 1 i7 core + Hyperthreading is slower than 2 i7 cores. I'm not sure how it works with current OSes. My assumption is that they will be switching between 2 logical and 2 physical threads(kinda chaotic).

In Windows 7, SMT parking will ensure Hyperthreading doesn't kick in until all the physical cores are in use, therefore the term "SMT parking".

Oh yea, you also got the 720QM Turbo Mode speeds wrong. It's 2.8GHz for 1 core and 2.4GHz for 2 cores.

 

2.8 and 2.4 are for the 1.6 one. 3.06 and 2.8 are for the 1.73. 3.2 and 3.0 are for the 2.00.

I think my mistake is in that they are 720 820 and 920 instead of 620 720 and 820? My mistake
