GeForce GT 430 1GB vs Radeon R7 M260

Intro

Compare all that to the Radeon R7 M260, which has a clock frequency of 715 MHz and a DDR3 memory speed of 1000 MHz. It also uses a 64-bit bus, and makes use of a 28 nm design. It features 384 SPUs, 24 Texture Address Units, and 8 ROPs.

GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 5960 (53%)

Pixel Rate

The Radeon R7 M260 should be much (approximately 104%) more effective at FSAA than the GeForce GT 430 1GB, and will be able to handle higher screen resolutions while still performing well. (explain)

Radeon R7 M260		5720 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 2920 (104%)

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 (counted in megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
