MSI GT683DXR Available and Shipping

msi gt683We mentioned the MSI GT 683DXR a while back. Now it has finally started to ship and it seems to be flying off the shelves. The main attraction in the 15.6-inch GT683DXR as opposed to the GT683R is of course that it comes with the new NVIDIA GeForce GTX 570M–a GPU that represents a significant step up in gaming performance over the GTX 560M that quite a few laptops are using right now.

There is, in fact, a huge difference between the GTX 560M and the GTX 570M. Although we still don’t have any reviews to go by, a quick look at the specs reveals that the 570M is equipped with 336 CUDA cores compared to 192 in the 560M. In comparison, NVIDIA’s top mobile GPU the GTX 580M has 384 shaders, although the memory clock is lower in the 570M and the latter shares the 192-bit memory bus with the 560M, while the 580M is 256-bit.

There is still little doubt that the 570M in the MSI GT683DXR is considerably faster than the GPU in the “regular” GT683R model. Just like the rest of MSI’s high-end gaming laptop lineup, the DXR also comes with the manufacturer’s proprietary overclocking feature that automatically overclocks the machine (both CPU and GPU) by at least 30% according to MSI. While the GPU is easy to overclock on your own–as we demonstrated in our GT 555M overclocking article yesterday–the CPU is nowhere near as easy to overclock.

There are two versions of the GT683DXR (in the U.S. at least)–one with the model name suffix 423US and another called 427US. Both are equipped with the GTX 570M, a Core i7 2630QM, USB 3.0, HDMI 1.4 and dual hard drives running in RAID 0. The only apparent difference is that the 427US comes with 16GB of RAM instead of “only” 12GB in the 423US. On the whole this looks like a very interesting machine that bridges the gap between laptops with the GTX 560M and those with the very expensive GTX 580M.
