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

Demoed unit has four times the number of CUDA cores
At 5 lb and 20 mm thick, Acer Inc.'s (
) 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. (
) Core i7-2637M, a 1.7 GHz
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. (
) has been noticeably absent from the graphics race this spring while rival Advanced Micro Devices, Inc. (
) 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
's benchmarks falls just short of the GTX 560M, but is overall solid.
The Acer Aspire TimelineU M3 is a slick piece of hardware, thanks to its Kepler GPU.

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.
Sadly, details about Kepler architecture-wise are scarce as there's an embargo on them. In fact Acer broke the embargo (accidentally) by airing the laptop, hence giving the world a sneak peek at Kepler. If the GT 640M is any indication, expect CUDA cores to receive around a 4x bump, putting NVIDIA likely ahead of AMD in computing power. At the same time expect lower clock speeds as NVIDIA -- like AMD -- adjusts to the perils of

So, how many CUDA cores is it?

Is it 4*384 = 1,536?

No, it's 384. the GT540 only had 92 cores, so 92 * 4 = 384.
