Earlier this year I had the chance to take a look at the first ultrabook with discrete graphics, the Acer Aspire Timeline Ultra M3. My review was not particularly favorable, but the idea of placing discrete graphics in an ultrabook is both compelling and necessary. Intel’s low-voltage processors have difficulty with gaming when paired with the HD 4000 IGP and this flaw is difficult to excuse in products typically priced at $800 or above. 

Four new ultrabooks with NVIDIA discrete GPUs have been unveiled to tackle the problem of gaming with a slim laptop. The list includes two laptops from Acer, two laptops from Gigabyte and one from ASUS.

The Gigabyte U2442N, which has a 14” 1600×900 display and a GeForce GT 650M GPU, is obviously the most powerful and the product that offers the most promising gaming experience on paper. Only the ASUS UX32 looks questionable. There’s no way that a GeForce GT 620M is going to handle gaming on a 1080p display. 

Unfortunately, a closer look at the announcement suggests these product lines aren’t that exciting. The Gigabyte laptops have received a lot of positive attention, but Gigabyte has no meaningful presence in the North American laptop market and it’s nearly guaranteed the laptop won’t be popular on this side of the pond. The Acer M5-581TG appears to be an Ivy Bridge updated version of the Acer Aspire M3 that we reviwed – and did not like – while the M5-481TG is just a smaller version. 

That leaves the ASUS UX32 and its GT 620M which, although likely quicker than Intel HD 4000, isn’t sufficient for serious gaming.

Hopefully NVIDIA will be able to bring discrete graphics to more products from larger manufacturers, but the fact so few companies have gone this route suggests there is some underlying reason. My personal guess? Heat. The Acer Aspire M3 became quite toasty during load. It’ll be interesting to see if the U244N has some design trick that makes the GT 650M manageable – or if Gigabyte, like Acer, doesn’t mind putting out a laptop with high exterior temperatures.
