GeForce GT 430 1GB vs Radeon R7 M265

Intro

The GeForce GT 430 1GB uses a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this model. It features 96 SPUs as well as 16 Texture Address Units and 4 ROPs.

Compare all that to the Radeon R7 M265, which has a clock frequency of 725 MHz and a DDR3 memory speed of 1000 MHz. It also features a 128-bit bus, and uses a 28 nm design. It features 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M265 should perform just 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 quite a bit (approximately 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 lots of anti-aliasing is important to you, then the Radeon R7 M265 is a better choice, 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.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
