Nvidia's new notebook GPUs of the Geforce 100M series supposedly offer an about 55 percent higher performance in comparison with the pendants of the 9000M series.

The most powerful notebook chip is called Geforce GT 130M and has more than 32 shader ALUs which are powered at 1,500 MHz. Nvidia announces a processing power of 144 Gigaflops. The memory clock is either 500 or 800 MHz, depending on the use of GDDR2 or GDDR3. The video memory is up to 1,024 MiByte big and has a 128 Bit interface width so that the bandwidth is 16 and 25 GB/s respectively.
Nvidia's Geforce G 110M is only provided with 16 shader ALUs which are powered by 1,000 MHz. The processing power with 48 Gigaflops is only a third in comparison with the GT 130M GPU. The memory has up to 1,024 MiByte and is powered by either 500 or 700 MHz - again depending on the use of GDDR2 or GDDR3. Due to the lower memory width of 64 Bit the bandwidth drops to 8 and 11 GB/s respectively.
With 1,600 MHz the mobile GPU Geforce G 105M has the highest shader ALU clock and with 8 shaders only it offers 38 Gigaflops. Memory clock and interface are the same as for the Geforce G 100M but the G 105M is supposedly provided with only 512 MiByte.
All Geforce 100M GPUs support PCI-E 2.0 interface, DirectX 10, OpenGL 2.1 and the Nvidia technologies Purevideo and Cuda. As you can see on Nvidia's website
the GT 130M is also suited for 2-way SLI and is ready for Physx calculation on a second GPU.
