GeForce GT 430 1GB vs GeForce GTX 750 Ti

Intro

Compare all of that to the GeForce GTX 750 Ti, which features a core clock speed of 1020 MHz and a GDDR5 memory speed of 1350 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the GeForce GTX 750 Ti will be 200% faster than the GeForce GT 430 1GB in general, because of its higher bandwidth. (explain)

GeForce GTX 750 Ti		86400 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 57600 (200%)

Texel Rate

The GeForce GTX 750 Ti will be a lot (about 264%) better at AF than the GeForce GT 430 1GB. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 29600 (264%)

Pixel Rate

The GeForce GTX 750 Ti is much (approximately 483%) more effective at FSAA than the GeForce GT 430 1GB, and will be able to handle higher screen resolutions better. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 13520 (483%)

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 maximum amount of data (counted in MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
