GeForce GT 230 vs Radeon R7 240

Intro

Compare those specs 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 model. It features 320 SPUs along with 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 240		30 Watts
GeForce GT 230		65 Watts
	Difference: 35 Watts (117%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 230 will be 33% faster than the Radeon R7 240 overall, because of its higher data rate. (explain)

GeForce GT 230		38400 MB/sec
Radeon R7 240		28800 MB/sec
	Difference: 9600 (33%)

Texel Rate

The Radeon R7 240 will be a lot (more or less 66%) better at AF than the GeForce GT 230. (explain)

Radeon R7 240		14600 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 5800 (66%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R7 240 is a better choice, by a large margin. (explain)

Radeon R7 240		5840 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 1440 (33%)

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 largest amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card 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 most pixels that the graphics chip could 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 ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
