GeForce GT 430 (OEM) vs GeForce GTX 965M

Intro

Compare those specs to the GeForce GTX 965M, which features GPU clock speed of 944 MHz, and 2048 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also is made up of 1024 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce GTX 965M should in theory perform much faster than the GeForce GT 430 (OEM) overall. (explain)

GeForce GTX 965M		64000 MB/sec
GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 35200 (122%)

Texel Rate

The GeForce GTX 965M will be quite a bit (about 439%) better at AF than the GeForce GT 430 (OEM). (explain)

GeForce GTX 965M		60416 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 49216 (439%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 965M is the winner, by a large margin. (explain)

GeForce GTX 965M		30208 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 27408 (979%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
