Santa Clara (CA) - Nvidia’s next-generation mobile graphics aren’t officially announced yet, but curious minds can already find some technical information about the new GPUs on Nvidia’s website.

The company has listed brief specifications for the 9300M G as well as the 9500M GS. The lower-end will get you 16 stream processors, a core clock of 400 MHz and a memory clock of 600 MHz. The chip can be combined with up to 256 MB memory. Step up to the 9500M and then you’ll receive 32 stream processors, a 475 core clock and a 700 Memory clock with up to 512 MB of buffer. If you look closely, you will notice that these specifications exactly mirror those of the 8400M GS and 8600M GT.

Asus apparently couldn’t wait for Nvidia to announce these new GPUs and today unveiled two notebooks integrating these chips. The 9300M G replaces the 8400M in the company’s 12.1” U6S model; the M51SN 15.4 notebook is available with the 9500M GS GPU.
