GeForce GT 430 vs GeForce GTX 950

Intro

Compare all of that to the GeForce GTX 950, which has a GPU core clock speed of 1024 MHz, and 2048 MB of GDDR5 RAM running at 1652 MHz through a 128-bit bus. It also is comprised of 768 SPUs, 48 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430		60 Watts
GeForce GTX 950		90 Watts
	Difference: 30 Watts (50%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 950 should in theory be a lot superior to the GeForce GT 430 in general. (explain)

GeForce GTX 950		105728 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 76928 (267%)

Texel Rate

The GeForce GTX 950 will be quite a bit (more or less 339%) more effective at texture filtering than the GeForce GT 430. (explain)

GeForce GTX 950		49152 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 37952 (339%)

Pixel Rate

The GeForce GTX 950 is much (approximately 1070%) faster with regards to full screen anti-aliasing than the GeForce GT 430, and should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 29968 (1070%)

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 largest amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR 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 number of texture units of the card 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 in a second.

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