GeForce GT 430 (OEM) vs Radeon R9 M295X

Intro

Compare all that to the Radeon R9 M295X, which uses a 28 nm design. AMD has set the core frequency at 750 MHz. The GDDR5 RAM runs at a speed of 1375 MHz on this particular model. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

Radeon R9 M295X		96000 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 84800 (757%)

Pixel Rate

The Radeon R9 M295X is much (approximately 757%) more effective at FSAA than the GeForce GT 430 (OEM), and will be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon R9 M295X		24000 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 21200 (757%)

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 information (counted in MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the 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 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 Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
