NVIDIA GeForce 9600M GT vs NVIDIA GeForce 9600M GS vs NVIDIA GeForce 9650M GT

NVIDIA GeForce 9600M GT

The Nvidia GeForce 9600M GT is a DirectX 10 graphics card for notebooks andsuccessor to the 8600M GT. Compared to the 8600M GT or 9500M GS, the 9600M GT was produced in 65nm (allows higher clock rates with the same current consumption) and features a new PureVideo HD video processor (VP3) and HybridPower support.

In conjunction with the Nvidia 9100M G integrated graphics, the 9600M GT supports Hybrid-SLI (only HybridPower). HybridPower is a technique to choose between the integrated and dedicated graphics core, if performance or battery runtime is needed. This works only in Windows Vista. Up to now the user has to use a tool to switch between the GPUs. Later Nvidia wants to switch automatically in the drivers. GeForceBoost is not supported with this card, as there would be no performance gain.

As the 8600M GT, the 9600M GT features 32 stream processors that do the graphic work of the vertex- and pixel-shaders.

The performance of the 9600M GT should be somewhere between the 9500M GS and the 8700M GT (depends if GDDR2 or GDDR3 memory chips are used).

Compared to desktop graphics cards, the 9600M GT is similar to the GeForce 9500GT (which also descends from the G96 core). The desktop CPU 9600 GT has a 256 bit memory bus and is therefore much faster.

NVIDIA GeForce 9600M GS

The Nvidia GeForce 9600M GS is a DirectX 10 graphics card for notebooks. Technically itis a slower clocked GeForce 9600M GT. It is also produced in 65nm and features a new PureVideo HD video processor (VP3) and HybridPower support.

Compared to the 8600M GT, the core clock is only slightly higher, which leads a similarperformance as the old 8600M GT, but because of the 55nm process it shoulduse less current. As the 8600M GT, the 9600M GT features 32 stream processors that do the graphic work of the vertex- and pixel-shaders.

In conjunction with the Nvidia 9100M G integrated graphics, the 9600M GS supports Hybrid-SLI (only HybridPower). HybridPower is a technique to choose between the integrated and dedicated graphics core, if performance or battery runtime is needed. This works only in Windows Vista. Up to now the user has to use a tool to switch between the GPUs. Later Nvidia wants to switch automatically in the drivers. GeForceBoost is not supported with this card, as there would be no performance gain.

Compared to desktop graphics cards, the 9600M GS is similar to the GeForce 9500 GS (which also descends from the G96 core). The similar named desktop CPU 9600 Series has a 256 bit memory bus and is therefore much faster.

NVIDIA GeForce 9650M GT

The Nvidia GeForce 9650M GT is a DirectX 10 graphics card for notebooks and  technically a higher clocked 9600M GT. It is produced in 55nm and therefore the current consumption is similar to the 9600M GT which is produced in 65nm. As the 9600M GT it features the PureVideo HD video processor (VP3) and HybridPower support.

In conjunction with the Nvidia 9100M G integrated graphics, the 9650M GT supports Hybrid-SLI (only HybridPower). HybridPower is a technique to choose between the integrated and dedicated graphics core, if performance or battery runtime is needed. This works only in Windows Vista. Up to now the user has to use a tool to switch between the GPUs. Later Nvidia wants to switch automatically in the drivers. GeForceBoost is not supported with this card, as there would be no performance gain.

As the 8600M GT and 9600M GT, the 9650M GT features 32 stream processors that do the graphic work of the vertex- and pixel-shaders.

The performance of the 9650M GT should be somewhere near the 9650M GS because of the high shader clock rate (with GDDR3). According to Zepto (first manufacturer who announced the card) the 9650M GT should be up to 20% faster than a 9600M GT (in 3DMark06).

Compared to desktop graphics cards, the 9650M GT is similar to the GeForce 9500GT (which also descends from the G96 core). The desktop CPU 9600 GT has a 256 bit memory bus and is therefore much faster.
