GeForce GT 430 (OEM) vs GeForce GTX 750 Ti

Intro

Compare all of that to the GeForce GTX 750 Ti, which uses a 28 nm design. nVidia has set the core frequency at 1020 MHz. The GDDR5 memory runs at a speed of 1350 MHz on this particular model. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce GTX 750 Ti, in theory, should perform a lot faster than the GeForce GT 430 (OEM) overall. (explain)

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

Texel Rate

The GeForce GTX 750 Ti will be much (more or less 264%) more effective at texture filtering than the GeForce GT 430 (OEM). (explain)

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

Pixel Rate

The GeForce GTX 750 Ti should be quite a bit (more or less 483%) better at FSAA than the GeForce GT 430 (OEM), and also capable of handling higher screen resolutions better. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
GeForce GT 430 (OEM)		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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core 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 output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
