Pretty much these:
14"
A45VS-VX026H, i5-3210M + Nvidia GT645M@RM2199[2.4kg], 2GB, 500GB, W8
K46CM-WX090H, i5-3317U + Nvidia GT635M@RM2199[2kg], 2GB, 500GB, W8, OD
15"
S56CM-XX090H i5-3317U + Nvidia GT635M + 24GB mSATA + 500GB@RM2199[2.3kg], 2GB, W8; color: black

K46CM battery hour depends on usage. If the GPU don't kick in, you could look at more than 3 hours (watch DVD etc). If you game on battery power, 1 hour if you are lucky

I understand that the A45 with 645M is the latest spec. The online shop that you check may be selling old stocks.

Which one is more important? Gaming - A45, Mobility - K46 (only by 400g though )

depends on wat programs u re going to run... if it's games then 3317U is still plenty enough...

well then it boils down to weight and design then... obviously A45VS will run games better due to the better graphic card... so ask urself which is more important to u: enjoy games at better detail, or a more handsome looking and lighter laptop?

Utter nonsense. Do you realise the i5 ULV is more expensive than the i5 M processor (one of the reason why ultrabook is more expensive than normal laptop). More expensive not because it run faster, but because it could be run at much lower voltage, and not all the chips coming off oven can pull it off.
3210M is running at 35W at 2.5GHz normal. When Turbo kick in (CPU under load), it go up to 3.1GHz.
3317U on the other hand, is running at 17W at 1.7GHz normal. When Turbo kick in, it go up to 2.6GHz.
So if you looking at top speed, 3210M win. But 3317U is running off 50% the power requirement (not so directly translated to real world performance since CPU only represent part of laptop total power consumption)
More over, 3317U can go down to 14W when idle.

I will take the best 2nd gen i3, i3-2370M as comparison. It run at 35W at 2.4GHz, and no Turbo available.

And the IGPU HD4000 in i5-3317U is so much better than the HD 3000 in i3-2370M.

Yes, BF3 at HD resolution is playable in K46CM. But being skinny, it don't dissipate heat that well, you better get good external cooling solution to prolong the life of laptop

thanks.. i think i will go for s56cm.. s56cm , k46cm, a45vs. this two model have dos or not?

Make sure you look at S56CM in real life and ok with the build quality before making the commitment

I wonder you or the machine will break down first
