GeForce GT 430 vs Radeon R7 M265

Intro

Compare those specs to the Radeon R7 M265, which has a clock frequency of 725 MHz and a DDR3 memory speed of 1000 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

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

Texel Rate

The Radeon R7 M265 will be quite a bit (approximately 55%) better at AF than the GeForce GT 430. (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R7 M265 is superior to the GeForce GT 430, and very much so. (explain)

Radeon R7 M265		5800 Mpixels/sec
GeForce GT 430		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 (counted in megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, 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 record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
