GeForce GT 430 vs Radeon R7 240

Intro

The GeForce GT 430 has core clock speeds of 700 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 memory. It features 96 SPUs as well as 16 TAUs and 4 ROPs.

Compare that to the Radeon R7 240, which uses a 28 nm design. AMD has clocked the core frequency at 730 MHz. The DDR3 RAM works at a frequency of 900 MHz on this particular card. It features 320 SPUs as well as 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 240 30 Watts
GeForce GT 430 60 Watts
Difference: 30 Watts (100%)

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The Radeon R7 240 is quite a bit (approximately 30%) faster with regards to anisotropic filtering than the GeForce GT 430. (explain)

Radeon R7 240 14600 Mtexels/sec
GeForce GT 430 11200 Mtexels/sec
Difference: 3400 (30%)

Pixel Rate

The Radeon R7 240 is much (more or less 109%) more effective at full screen anti-aliasing than the GeForce GT 430, and also should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon R7 240 5840 Mpixels/sec
GeForce GT 430 2800 Mpixels/sec
Difference: 3040 (109%)

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 max amount of information (in units of megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 can be processed per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per 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 colour ROPs by the the card's clock speed. 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 lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
