GeForce 9500 GT 1GB GDDR3 vs Radeon R7 240

Intro

The GeForce 9500 GT 1GB GDDR3 comes with a clock speed of 550 MHz and a GDDR3 memory frequency of 800 MHz. It also makes use of a 128-bit bus, and makes use of a 55 nm design. It features 32 SPUs, 16 TAUs, and 8 Raster Operation Units.

Compare those specifications to the Radeon R7 240, which makes use of a 28 nm design. AMD has clocked the core frequency at 730 MHz. The DDR3 RAM is set to run at a speed of 900 MHz on this particular model. 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 9500 GT 1GB GDDR3 50 Watts
Difference: 20 Watts (67%)

Memory Bandwidth

In theory, the Radeon R7 240 is 13% quicker than the GeForce 9500 GT 1GB GDDR3 in general, due to its higher data rate. (explain)

Radeon R7 240 28800 MB/sec
GeForce 9500 GT 1GB GDDR3 25600 MB/sec
Difference: 3200 (13%)

Texel Rate

The Radeon R7 240 is a lot (more or less 66%) more effective at anisotropic filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

Radeon R7 240 14600 Mtexels/sec
GeForce 9500 GT 1GB GDDR3 8800 Mtexels/sec
Difference: 5800 (66%)

Pixel Rate

The Radeon R7 240 should be quite a bit (about 33%) more effective at full screen anti-aliasing than the GeForce 9500 GT 1GB GDDR3, and will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon R7 240 5840 Mpixels/sec
GeForce 9500 GT 1GB GDDR3 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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of 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 in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock 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 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 max fill rate.
