GeForce GT 430 1GB vs Radeon R7 M265

Intro

Compare all that to the Radeon R7 M265, which uses a 28 nm design. AMD has set the core speed at 725 MHz. The DDR3 memory works at a speed of 1000 MHz on this model. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M265 should perform a bit faster than the GeForce GT 430 1GB overall. (explain)

Radeon R7 M265		32000 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 3200 (11%)

Texel Rate

The Radeon R7 M265 is much (more or less 55%) more effective at texture filtering than the GeForce GT 430 1GB. (explain)

Radeon R7 M265		17400 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 6200 (55%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 M265 is the winner, and very much so. (explain)

Radeon R7 M265		5800 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 3000 (107%)

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 largest amount of information (in units of MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the 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 processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per 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 amount of Render Output Units 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 rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
