Acer Airs Kepler-Sporting TimeLine U3, Puts the Ultra in Ultrabook

From DailyTech: At 5 lb and 20 mm thick, Acer Inc.'s (TPE:2353) TimelineU M3 is a bit of a beefy 15.6-inch pseudo-Ultrabook. But what it lacks in slender figure, it makes up for in pure power.

It comes with a Intel Corp. (INTC) Core i7-2637M, a 1.7 GHz dual-core Sandy Bridge part that can Turbo up to 2.8 GHz, a 1366x768 screen, 4 GB of 1333 MHz DDR3 RAM, a 256 GB SSD from Lite-On, and a DVD+RW drive. But its real treasure is its GeForce GT 640M GPU.

Yes, that's a Kepler GPU.

NVIDIA Corp. (NVDA) has been noticeably absent from the graphics race this spring while rival Advanced Micro Devices, Inc. (AMD) rounded out its lineup. However, NVIDIA is charging back, leveraging its strength of GPU computing. The GT 640M comes with 384 CUDA cores (8 streaming multi-processors), putting it on par with a GTX 460 or a GTX 570M.

Like AMD, NVIDIA is targeting lower clock speeds for its first 28 nm parts. The GT 640M is clocked at 625 MHz for the core (versus 672 MHz for the GT 540M). The part is somewhat limited by a 128-bit bus, and DDR3, instead of dedicated GDDR5. Still gaming performance in Anandtech's benchmarks falls just short of the GTX 560M, but is overall solid.

The laptop showed an impressive 417 min. of battery life on its 55 Wh battery -- rather impressive. The laptop is also cooler than previous powerhouses. In both metrics the advantage of NVIDIA's new 28 nm and Intel's 32 nm processes are showing.
