GeForce 9500 GT DDR2 vs Radeon R7 240

Intro

Compare those specifications to the Radeon R7 240, which comes with a core clock frequency of 730 MHz and a DDR3 memory speed of 900 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is comprised of 320 SPUs, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 240		30 Watts
GeForce 9500 GT DDR2		50 Watts
	Difference: 20 Watts (67%)

Memory Bandwidth

As far as performance goes, the Radeon R7 240 should in theory be much superior to the GeForce 9500 GT DDR2 overall. (explain)

Radeon R7 240		28800 MB/sec
GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 12800 (80%)

Texel Rate

The Radeon R7 240 should be much (more or less 66%) faster with regards to texture filtering than the GeForce 9500 GT DDR2. (explain)

Radeon R7 240		14600 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 5800 (66%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R7 240 is a better choice, by far. (explain)

Radeon R7 240		5840 Mpixels/sec
GeForce 9500 GT DDR2		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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
