NVIDIA Announces its First 40 nm, DirectX 10.1 Compliant GPUs
NVIDIA today announced its latest line of mobile graphics processors (mGPUs) based on the new 40 nm manufacturing technology. The GPUs also come as a surprise, as they embrace two technologies very few expected them to, this early/late. The GPUs support the DirectX 10.1 API, and some feature the new GDDR5 memory interface that doubles effective bandwidth. Enter GeForce GTS 260M, GTS 250M, GT 240M, GT 230M, and G 210M.
The G 210M succeeds the GeForce 9400, at least as far as the manufacturing technology and clock speeds go. It holds 16 shader processors, a 64-bit GDDR3 memory interface, and 512 MB of memory. The GT 230/240M hold 48 shaders, 1 GB of 128-bit GDDR3 memory, and clock-speeds that make up each variant. The GTS 260/250M are especially new, as they feature a 128-bit GDDR5 memory interface. 96 shaders and 1 GB of memory make the rest of their specs., while their clock speeds make for the variants. The table below spreads out the specifications.The peculiar thing about these GPUs is their timing of entry into the market. This is the fag-end of the DirectX 10(.1) generation of GPUs, with no more high-end GPUs in sight. The company is facing stiff competition from AMD, and needs to cut manufacturing costs, while also decorating specs sheets. The use of GDDR5 allows manufacturers to narrow memory bus width, and reduce the number of memory chips, in turn board footprint, while maintaining the same levels of performance as GDDR3 with higher bus width. The use of 40 nm manufacturing process is certainly a step in the right direction, although we wonder how the company is able to get large yields of these chips, considering AMD isn't able to keep up with demand for its 40 nm GPUs, and is developing alternative SKUs at the same price points.

the power consumption ... since powerful 55nm mobile GPUs draw lot of power and
the DDR5 too will contribute by using less power ..... like to see some benches .....
Hmmmm ....I'm eager too know wat kind of performance the GTS 260 offers ....
He's basically saying that there are really 3 gpus using 5 skus (look at the Processor Cores AKA Shader Units).
I hate how nVidia does their mobile GPUs.
I think the 4870 moblility is a 4830, that is slower than desktop.
So, why is nVidia still giving us 96 shaders? That is ridiculous for 40nm.
These must simply be the starter set, the midrange chips. I'm certain we'll see GTX 280M with 192 SP's soon enough, alongside mobile Quad cores.
nvidia's mobility chips are just rebranded & shrinked 8800 chips

I think i wanna see an ATI/Intel Quad based laptop show up Id prolly buy that.
Good example is a ATI GPU core does physics better than the Nvidia core of the same class; BUT the Nvidia card will have an Aegis physics chip that it offloads the physics to which gives it a huge boost in physics. It definitely has a huge number of PPU's that don't get counted when shader specs are listed.
