NVIDIA Announces GeForce GT 540M Notebook GPU
NVIDIA introduced the GeForce GT 540M notebook GPU, the first GPU in our GeForce 500M family of notebook GPUs. OEMs are launching these Optimized notebooks with GeForce GT 540M GPUs and dual-core "Arrandale" CPUs in order to hit mainstream price points sooner, ahead of Huron River dual-core platforms that will not be released until later in 2011. It is available immediately in China from Acer, and will be available worldwide next month.
With GeForce GT 540M, we are taking an already proven architecture and using the maturity of the manufacturing process to create GPUs with higher clock settings while staying in the same power envelope. As a result, the GeForce GT 540M delivers a significant increase in fill-rate and memory bandwidth, which ultimately translates to better overall performance.
GeForce GT 540M GPUs are DirectX 11 done right, and like all GeForce GPUs, they support the differentiating features that set our GPUs apart from the competition, including: NVIDIA Optimus technology, PhysX, 3D Vision, 3DTV Play, CUDA, and Verde drivers to keep your notebook optimized for tomorrow.

This is a GF108, it has 16 TMUs and 4 ROPs, while the G92 (in the GTX260M) has 56 TMUs and 16 ROPs. The GTX260M may not have much better shader performance, but it has a huge fillrate and texture processing advantage.
This GPU's performance should be a lot closer to a G94 (9600GT, 9800M GS) than a GTX260M.
In the end, it's probably not faster than the speedier versions of the Redwood-based AMD solutions (Mobility HD5730/70), so it's hardly a "new notebook graphics king".

This should be called the GT440m and nothing more. Heck the 4xx series havn't been out long themselves.
As for performance well the GT435m is generally slightly slower than the GT335m (72 GT200 based shaders, 8 ROPS, 128bit GDDR3) assuming the rest of the laptop is specced the same.
It will still be noticably slower than a 9800mGT (8800mGTX) and roughly on par with the HD5650 mobility or HD5730 mobility running GDDR3 (the HD5730 is just a HD5650 clocked higher and with the ability to run GDDR5).
In desktop terms we are comparing a downclocked GT430 and a GDDR3 HD5570.
Anandtech have done plenty of reviews covering these GPU's (Dell XPX15 is probably the most recent review covering the GT435m) and the are all much of muchness.
