Santec, an Italian custom notebook manufacturer, has just updated the configuration options list of one of its flagship laptop designs in order to feature Nvidia's GTX 580M graphics core, which isn't expected to become official until June 22. The system in question is called the Santec N67 and users have the option of configuring it with Intel second-generation Core i7 quad-core processors ranging from the 2.2GHz 2720QM to the 2.5GHz 2920XM Extreme Edition. These can be paired together with up to 16GB of DDR3-1333 or DDR3-1600 system memory as well as with a 750GB hard drive spinning at 7200RPM or with a 300GB solid state drive. While these are indeed some very nice components to have on a high-end notebook, the most important addition brought by Santac to the N67 is the inclusion of Nvidia's yet-unreleased GTX 580M graphics card. Technical characteristics were kept to a minimum, so there isn't that much information available about the GTX 580M, but we do know that the GPU can be paired together with 2GB of GDDR5 memory and that it will most probably feature a 100W TDP. Just as all Nvidia's high-end mobile graphics cards, the GTX 580M will also feature a 256-bit memory bus and supports the PhysX and CUDA technologies. The Santec N67 notebooks can already be configured on the company's website, but it won't start shipping until June 22, which could indicate this is the date chosen by Nvidia for the launch of this new flagship mobile GPU. The GeForce GTX 580M was designed to replace the GTX 485M, which was launched in January of this year and is based on the GF104 core. The GF104 is also used in the desktop GTX 560 Ti graphics card and it packs no less than 384 stream processors, 64 texture units, 32 ROP units as well as a 256-bit wide memory bus.
