GeForce GT 430 1GB vs GeForce GTX 965M

Intro

Compare all of that to the GeForce GTX 965M, which features GPU core speed of 944 MHz, and 2048 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also is comprised of 1024 Stream Processors, 64 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the GeForce GTX 965M should in theory be much better than the GeForce GT 430 1GB overall. (explain)

GeForce GTX 965M		64000 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 35200 (122%)

Texel Rate

The GeForce GTX 965M should be much (approximately 439%) better at AF than the GeForce GT 430 1GB. (explain)

GeForce GTX 965M		60416 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 49216 (439%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 965M is a better choice, by a large margin. (explain)

GeForce GTX 965M		30208 Mpixels/sec
GeForce GT 430 1GB		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: Bandwidth is the largest amount of data (in units of MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
