14 DAY TRIAL // Nvidia is getting ready to replace its top of the line mobile graphics core, the GTX 485M, with a new 500-series GPU that will be called the GTX 580M. The new chip will deliver improved performance and is expected to arrive later this summer.
Just as the current GeForce GTX 485M mobile GPU, Nvidia's upcoming graphics processor will target 17-inch, or larger, notebooks and will also support Nvidia's SLI technology.
Using SLI, notebook makers can build devices that house two such cards in order to deliver even faster graphics performance.
Doing so will however require a massive cooling system as the TDP of the GTX 580M is expected to be rated at 100W. Just as all the other GTX 500-series mobile GPUs in Nvidia's lineup, the GTX 580M will also support the Optimus graphics switching technology.
Sadly, this is all the information that is available for now about Nvidia's upcoming flagship, so we don't know on what core will this be based on or just how much shaders it will pack.
Nvidia has released the GTX 485M in January of 2011 and it replaced the previous GTX 480M.
This is based on the same GF104 core as 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.
Notebook makers can link this to 2GB of GDDR5 video buffer, which has a default operating frequency of 750MHz (3GHz data rate). The GF104 core is clocked at 575MHz.
Nvidia's GeForce GTX 485M is available in various notebook models manufactured by the likes of AVADirect, Clevo, Eurocom, or Maingear, to name just a few.
As noted earlier, Nvidia is expected to launch the GTX 580M later this summer. (via Fudzilla)
