GeForce GT 430 1GB vs Radeon R7 M265

Intro

Compare all of that to the Radeon R7 M265, which makes use of a 28 nm design. AMD has clocked the core frequency at 725 MHz. The DDR3 RAM is set to run at a frequency of 1000 MHz on this model. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M265 should be 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%) faster with regards to anisotropic 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

The Radeon R7 M265 should be quite a bit (more or less 107%) more effective at AA than the GeForce GT 430 1GB, and will be able to handle higher screen resolutions without slowing down too much. (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 maximum amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
