Nvidia mobile GPU technology changed its direction in
2011 when they developed the GTX500 GPUs. This GPU was designed for playing
latest games at max quality on laptops. In 2012 they made a step forward with a
GTX600 series which were more optimized towards efficiency and performance.
This year Nvidia developed next generation of GPUs for laptops called GTX700M.
According to Nvidia webpage the new GTX700M is
bringing more than just performance. This new GPU comes with GPU Boost 2.0, the
GeForce Experience, and NVIDIA Optimus technology so you will be able to play
the games in high quality.
As I mentioned earlier the GTX 600 Series GPUs have
won universal acclaim for their efficiency and performance thanks to the
introduction of a new design architecture called Kepler. With this new design
the power consumptions has been dramatically reduced whilst maximizing
performance. The performance of mid-range GeForce GTX 660 performs almost
identically in games to the previous-generation flagship GPU, the GTX 580.
On desktops, improved power efficiency, reduced heat
output, and better acoustic performance are nice bonuses on top of
class-leading pixel pushing prowess, but in notebook land they’re vital.
Improved power efficiency increases battery life, reduced heat output enables
the use of smaller, lighter chassis that are cooler to the touch, and better
acoustic performance means less fan whirring, which makes notebook use far more
pleasant. The Kepler architecture is featured predominately throughout the 700M
GPU uses this, significantly increasing performance compared to 600M “Fermi”
GPUs and Integrated Graphics Processors:
At medium detail levels the 700M Kepler GPUs can
accelerate notebook performance greatly which will result up to 90 frames per
second in Starcraft II, 65 frames per second in The Elder Scrolls V, 66 frames
per second in Shogun 2. For example even today the Intel Graphics Processors
struggle to break into the double digits of frames per second. Helping our new
700M chips reach such lofty levels of performance is GPU Boost 2.0, a GPU innovation
that extracts every ounce of available computing power from the graphics
processor. Before GPU Boost, GPUs were held back by synthetic benchmarks that
pushed chips and power usage to the limit, far beyond the levels typically seen
when playing games. This ‘worst case scenario’ forced us to throttle GPUs,
leaving spare performance on the table when playing games. GPU Boost resolves
this problem by monitoring power usage and temperatures, enabling the GPU to
use every last ounce of performance without exceeding safety or comfort limits.
When you are not playing games or using GPU-s
accelerated application, Optimus kicks in, automatically switching the display
to the lower-power Integrated Graphics Processor. For example when you’re not
playing games and you’re surfing on the Internet the NVIDIA GPU will be
disabled, but the second you start working with graphics the Optimus will
enable GPU to make use of GPU computation power, ensuring the top performances. Combined,
Optimus, GPU Boost, and Kepler maximize system efficiency and give notebook
users the optimum level of performance at all times, automatically.
