GeForce GTX 295 vs Radeon R7 240

Intro

Compare those specs to the Radeon R7 240, which features core clock speeds of 730 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. 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 GTX 295		289 Watts
	Difference: 259 Watts (863%)

Memory Bandwidth

In theory, the GeForce GTX 295 will be 677% quicker than the Radeon R7 240 in general, due to its greater data rate. (explain)

GeForce GTX 295		223776 MB/sec
Radeon R7 240		28800 MB/sec
	Difference: 194976 (677%)

Texel Rate

The GeForce GTX 295 should be much (more or less 531%) more effective at AF than the Radeon R7 240. (explain)

GeForce GTX 295		92160 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 77560 (531%)

Pixel Rate

The GeForce GTX 295 should be quite a bit (approximately 452%) more effective at FSAA than the Radeon R7 240, and also should be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 295		32256 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 26416 (452%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
