Sandy Bridge vs Nehalem Vs Westmere

[jakaranda]

Hello,

I am looking to buy a high end laptop to do my meshing and pre/post processing on the go.
I am wondering which Intel architecture would give me the best performance.

It is not clear ot me which of the 3 intel chips (Sandy Bridge/Nehalem/Westmere gives the best performance for a laptop. I know that the Westmere is better then the Nehalem for CFD desktops applications (higher memory bandwidth and more cores for same price). But what about for laptops and what about the sandy bridge chip?

Does anybody have any recommendations for laptops/manufacturers giving what they feel is currently the best high end bang for the buck?

Thank you

For laptops? Sandy Bridge. Forget everything else.

Yeah it's not even close.

No question about this.

When they finally do come out (the entire generation of laptops based on Sandy Bridge was delayed by the recall) one of those has my wife's name on it.

They have already been out... but the fixed chipset should be out march.

theres a westmere lappy?

Really?

As far as i know, there is no westmere, its bloomfield.

This is the first time ive heard of them.

If the westmere is a lappy, by far, it will be the best, seeing how the westmere is a Xeon branded cpu, and can go up to a hexcore.

However i dont think there is a westmere lappy, unless were going into the ultra high gaming DTR's which arent exactly lappys.
And DTR > Lappy in power, unless u want portability and energy saving features.

Then a Sandy wins if you average all.

Arrandale is Westmere. Unless the OP doesn't know it, but that doesn't change anything.

so tell me a lappy with more power then a DTR hexcore westmere?

You can get a laptop with a 980x and dual 485m in SLI for about 6 grand.

the 980X is a hexcore gulftown, is also be called a westmere on the Xeon side.

OP asked for:

best high end bang for the buck

Not sure of what you are talking about is really bang-for-buck sensitive. Surely it delivers on the performance.

Asus G73 - the model with the GTX460M NOT the AMD 5870.
Put a decent SSD in it and it's a lot of bang for the buck. (Under $1800 WITH SSD and 8GB RAM)

Iv got the model with the 5870m and its still good so if you can find it for cheaper then the 460m it wouldnt be bad.

the most powerful laptop, is a westmere DTR.

DTR = desktop replacement.

Its a class where u lump those 45min laptop's in, meaning they only last 45min on the battery.

Those laptops would kill any sandy laptops because power consuption wasnt something they though of in the area's of being frugal.

OMG i almost spelled frugal = froogle...

GOD DAYAM GOOGLE! taking over the world is no joke.


If you want to ask my personal opinion, i like HP on the business side. NOT Consumer side, with evny blingness.

I perfer the business class laptops in the Elite book zone.

Add a secondary battery, yes they can take 2, and u got almost 8-9 hours of battery life on a 17inch monitor.

That is what i use... and i love it..
I'll change to the Sandy when its matured.

But if u need a laptop NOW, and price is no option, the elitebook from HP with the IPS screen is about the best u can get IMO.

i7 980X vs. i7 2820QM

(ignore that the Sandy Bridge system is using the HD 3000 graphics and the 980X one is using 480M SLI)

Well, for absolute performance I guess you can't go wrong with the 980X.

It doesn't look like a killing since its a desktop chip with +50% more cores and its being compared to a laptop one. Kinda amazing how close it is.

i7 2820QM vs i7 820QM: http://www.anandtech.com/bench/Product/327?vs=280

It's like comparing Core 2 to the very first Northwood P4 chips.

Ahh Westmere. Had so much potential but intel fumbled the ball

It does. You can get a 990X in a laptop, if you have the balls for it.

It is going to be 50% faster for pure multithreaded stuff. If you have $3500 burning a hole in your pocket and you do multithreaded stuff, well...

The PC Torque guys are pretty nice, btw. If you want something more reasonable, you can get SB/Optimus in a 15.6" for a little over a grand https://secure.pctorque.com/system-configuration.aspx?SystemsID=57

if you are willing to drop corporate security features + some speed, the i7-2620QM will probably save a pretty penny compared to the i7-2820QM
