Lenovo IdeaPad U300s Ultrabook Review

Maxon's Cinebench R11.5 benchmark is based on the company's Cinema 4D software used for 3D content creation and tests both the CPU and GPU in separate benchmark runs. On the CPU side, Cinebench renders a photorealistic 3D scene by tapping into up to 64 processing threads (CPU) to process more than 300,000 total polygons, while the GPU benchmark measures graphics performance by manipulating nearly 1 million polygons and huge amounts of textures.

In the CPU component of this test, the U300s is right in line with the other ultrabooks in its class.  However,  in the OpenGL test, which excersizes the graphics core in its Core i7 processor, we see that memory bandwidth issue cropping up again.  Conversely, the U300 still manages to outpace Toshiba's lower cost offering and doesn't trail the other ultrabooks all that much.

Far Cry 2 and Left 4 Dead 2 Gaming Tests
DX 9 and DX10 Light Duty Gaming Performance

 


FarCry 2

Like the original, FarCry 2 is one of the more visually impressive games to be released on the PC to date. Courtesy of the Dunia game engine developed by Ubisoft, FarCry 2's game-play is enhanced by advanced environment physics, destructible terrain, high resolution textures, complex shaders, realistic dynamic lighting, and motion-captured animations. We benchmarked the test systems in this article with the FarCry 2 benchmark tool using one of the built-in demo runs recorded in the "Ranch" map.


If you're considering an ultrabook primarily for gaming on the go, you had best reconsider.  That said, it's not like a little light duty action is completely out of the question.  The U300s trails the Asus and Dell machines by a hair, again likely due to that memory bandwidth issue.  Again, however, the difference is negligible and at these resolution and image quality settings, none of the machines shown here are putting up playable frame rates.  Drop the resolution and/or IQ settings and things should smoother out a bit more.


Left 4 Dead 2, though it has reasonably good visuals, is a bit easier on the graphics subsystem.  This was a game engine that the Lenovo IdeaPad U300s could handle a bit better as well.



Here we see playable frame rates right up through 1280X720 and almost playable at native res of the U300s panel.  We only had reference numbers from the Dell XPS13 but, as you can see, Dell's advantage is on the order of about 10% or so.

Again however, we're certain you're not as concerned with a lot of gaming results with an ultrabook, so we'll move on to something more critical, battery life performance.

So, I guess the new generation portable pc has no DVD/CD drive huh? Makes sense. Would it stand against a MacBook Pro on thgraphics aspects? Sure would like to know.

scrEaMingmANgo, The 13-inch MacBook Pro has a very similar processor with integrated graphics. So, yes, this machine would compete relatively well versus the Apple product.

Are there enough benchmarks that would run on both Macs and Ultrabooks that you could start to include the Mac in these comparisons, since that's the whole point of Ultrabooks to begin with?

In previous laptop models I found 8GB of memory to be important and yet this Ultrabooks category seems to be 4GB. Is there something that is making 8GB unnecessary?

0

Technically, 8GB has always been unnecessary. 4GB in the average notebook these days is fairly robust for most usage models, especially an ultralight like this. If you're working with large amounts of HD video or other heavy workloads, it might come in handy but for the most part, 4GB is enough for many usage models.

8GB has always been unnecessary? As a computer programmer, I must completely disagree! To proclaim that, because the masses don't need it, it must be "always unnecessary" is completely false.

We tested the 13.3" 6GB RAM version that is being in sold in India. Check out our review at: http://www.haplessgeek.com/2012/04/analyzed-lenovo-ideapad-u300s-ultrabook.html

A lot of people over 40 wish they could buy one of these, but the high screen resolution makes everything too small for their eyes. This unit has a PPI (pixels/inch) of 117.83.   With reading glasses optimized for computer use, I still can't use a notebook over 100 PPI.

The ZOOM feature in browsers and MS Office helps but ZOOM does not help with system objects such as Menus.

The custom DPI setting in Windows helps, but this settings causes the fonts in many applications to spill out of their menu boxes or form fields.

I know that many readers can't relate to this issue, but notebook makers are shutting out 30% of their potential market by only offering Ultra-High res wide screens.

This PPI calculator may be helpful for those who are shopping with screen resoltuion as a primary criteria.
