8662 vs 8690 / 260m vs 280m Questions

I am trying to find some good "apples to apples" game benchmarks (Crysis, etc) between the 260m found in the Sager 8662 (and Asus G51J) and the 280m found in the Sager 8690.

I'm not having any luck. Does anyone have a link they can share?

 

280m is slightly faster than the 260m not alot in it though.

 

Try the xoticpcforums.com site, look in the review section. I know the Crysis benchmarks were posted for the NP8690.. You'll have to check on the 8662, but might find them in the G51J review post.

 

Yeah, that's where I have been looking. Apart from Futuremark benches, there aren't benchmarks for the same games to compare to. It's hard to tell, for instance, just how much of a fps increase the 280m would give you over the 260m in game like Crysis when both machines are set to the same settings.

My current laptop has an 8800GTS and I'm curious how much of an improvement both the 260m and the 280m would have over that so I can determine the cost/performance advantages. I'm scratching my head because it's not usually that hard to find these things. I figured I must just be looking/searching in the wrong places or something.

 

GTX260m would be like 8800GTS SLI , and the GTX280m would be just a bit more ( like higher clocks ). The 260 and 280 would be like 2-3 FPS apart in a 30ish FPS average. there are only 16 more procs in the 280m which can make a difference with games like crysis, but most games you wouldn't really notice much of a difference.

And here is the 280m

http://www.xoticpcforums.com/showthread.php?t=3919 I would recommend this for more accurate 280m results though.

Honestly though, GTx260M benchmarks are going to be alot harder to find right now especially apples to apples, you can also check the W860 review ( it's equipped with a GTX260m and Core i7.) www.notebookjournal.de same with the other link, you'll need a translator unless you speak Duetsche, but you can still read the graphs. It's under Top 10, then under notebooks up to 16.4'' and the W860 is the first one.

 

Since you're in the Sager forum, I'm guessing this probably isn't too relevant, but beware of benchmarks from the Asus G51 260M. Asus underclocks them from the factory due to heat issues.

 

550mhz core vs 583mhz and 112 shaders vs 128 shaders

The difference is unremarkable, but exists. 10% at best.

 

I suppose that should factor into things as well. You see, I ordered a G51J but I've been wrestling whether or not I've made the right choice as opposed to an 8690. Money is tight, so if I spent the extra $, I'd like to know what the real world performance benefit would be.

I know about the "heat issue" and other things to compare. The thing I was lacking was the performance benefit between the two, which is why I thought I'd ask here since Sager has the 8662 (for the 260m) and the 8690 (for the 280m).

The other thing I'm unsure about is how reliable I can expect an 8690 to be and whether or not I would want to invest in an extended warranty. That adds a good bit to the price as well.

 

Is anyone willing to post some Crysis benchmarks for the 8690 at 1920x1080, 1600x900? Or perhaps point to someone's post who has?

 

From the xoticpcforums..

 

Awesome, thanks! From the looks of things, there seems to be about a 5-8 fps difference between the 260m and 280m depending on resolution under Crysis.

 

You're going to see a bigger difference between the 280m on the Sager vs. the 260m on the Asus due to the underclocked 260m as was previously mentioned.
