GeForce GT 430 1GB vs Radeon R9 280X

Intro

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

Compare that to the Radeon R9 280X, which uses a 28 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 RAM runs at a speed of 1500 MHz on this specific card. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.

The Radeon R9 280X is quite a bit (approximately 871%) better at AF than the GeForce GT 430 1GB. (explain)

Radeon R9 280X 108800 Mtexels/sec
GeForce GT 430 1GB 11200 Mtexels/sec
Difference: 97600 (871%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 280X is superior to the GeForce GT 430 1GB, by a large margin. (explain)

Radeon R9 280X 27200 Mpixels/sec
GeForce GT 430 1GB 2800 Mpixels/sec
Difference: 24400 (871%)

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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
