Now not taking into account vcore temp, how does SB fare ?

post #1 of 4
Thread Starter 
See I don't have desktop anymore I'm going laptop only very soon. From what I'm seeing benchmarking between core i7 & the 2600k at the same clock they seem to have the same results. The main diff is the temp is lower wither also lower vcore for the 2600K cpu.

My question is with my future laptop I'm not going to try any kind of OC with the cpu, so with that in mind should I still wait for SB laptops or should I get the core i5 laptop I've been eyeing for a while ?

I mean if I ain't going to OC my cpu is there any benefit (other than better battery time) in waiting for the SB laptop ?

I like to play emulators like mame and some others and I want to get the best clock fr cpu for emulators. For example when I had a E6850 @ 3.0GHz is was good when I replaced it with also a 3.0GHz core i7 is was much better & faster and thats also with 3.0GHz clock.

My question is if I get a SB cpu that has the same clock speed same amount of cores same series cpu as a core i5 will I see a diff like I did when I upgraded to core i7 from a conroe E6850 ? If not as big as a dff how big do you think ? 5-10% maybe ?

thanks

It depends if you want to have four cores or you are happy with a dual core laptop. The last generation of Intel mobile quads were very power hungry, fairly hot and overall lacked the absolute clock speed to be convincing buys. That said the most important factor determining heat is TDP and as far as I known Sandy Bridge does better in that department than Clarksdale did.

Well I want a core i5 560M dual core or whatever is the SB equivalent. Do you think both clocked at the same speed will the SB do more per instruction ? Basicly which can do more with the same speed how by how much of a diff ?

About 10% clock for clock.

SB chips are generally clocked about 10% faster.

I would say you would get an aggregate of 15-20% increase in performance from the last generation 32nm chips. That said they are less power hungry so you will do more per watt (which is more relevant in the mobile space than it is in the desktop).
