GeForce GT 430 (OEM) vs Radeon R7 240

Intro

Compare all that to the Radeon R7 240, which comes with core speeds of 730 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs as well as 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The Radeon R7 240 will be quite a bit (more or less 30%) faster with regards to AF than the GeForce GT 430 (OEM). (explain)

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

Pixel Rate

The Radeon R7 240 will be quite a bit (approximately 109%) better at FSAA than the GeForce GT 430 (OEM), and also able to handle higher resolutions without losing too much performance. (explain)

Radeon R7 240		5840 Mpixels/sec
GeForce GT 430 (OEM)		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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the 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 applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video 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 most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
