GeForce GTX 570M Available in MSI's GT683DXR and GT780DXR

We've known the GTX 570M was coming for a while now, but MSI is the first to start shipping notebooks with the new GPU. Sitting between the GTX 560M and GTX 580M, the GTX 570M packs 336 CUDA Cores clocked at 1150MHz, with 3GB of  GDDR5 running on a 192-bit bus and clocked at 3GHz (72GB/s of bandwidth). That compares to 192 cores clocked at 1550MHz with 2.5GHz GDDR5 (60GB/s) for the GTX 560M, giving the 570M 20% more bandwidth and 34% more processing power. The big brother GTX 580M on the other hand comes with 384 cores clocked at 1240MHz, with 3GHz GDDR5 on a 256-bit bus (96GB/s), so it has 33% more bandwidth and 23% more processing power.

Like all the 500M GPUs (and the 400M parts before them), the 570M supports NVIDIA's Optimus graphics switching technology, though it's up to the notebook manufacturers to actually use it or not. Unfortunately, it appears MSI has decided to not support Optimus with their G-series updates, so we'll have to wait for a future model to get that feature.

That brings us to MSI's new notebooks. The GT683DXR and GT780DXR update the GT680R and GT780R respectively. We reviewed the GT580R a few months back, and it sits in the middle of a bunch of similarly specced notebooks. The new model upgrades the GPU along with packing in 12GB RAM (2x4GB + 2x2GB), keeps the 2x500GB RAID 0 hard drive setup, and continues to offer a GPU overclocking tool dubbed Turbo Drive Engine (TDE) that boosts GPU clocks 3-5%. Newegg and Amazon already have the GT683DXR in stock, priced at $1600 and $1594 respectively.

The larger GT780DXR sports roughly identical specs, with the chief difference being the larger chassis and 17.3" display. The GT780DXR also includes a third USB 2.0 port and a VGA port, to go along with the two USB 3.0 ports and the HDMI port offered on the GT683DXR. and it has a backlit keyboard with three color zones. We haven't had a chance to look at the GT780 series before, so we can't comment on the display quality, but it can hardly be worse than the panel we tested in the GT680R. Considering it costs an extra $100 for a larger notebook with otherwise identical specs, not to mention the use of a matte LCD, we're hopeful that display quality is substantially better on the GT780DXR. The GT780DRX is also available at Newegg for $1700, or at Amazon for $1700.
