GeForce GTX 590 vs Radeon R7 240

Intro

Compare all of that to the Radeon R7 240, which comes with GPU core speed of 730 MHz, and 2048 MB of DDR3 memory running at 900 MHz through a 128-bit bus. It also features 320 Stream Processors, 20 Texture Address Units, and 8 ROPs.

Radeon R7 240		28800 MB/sec
	Difference: 299520 (1040%)

Texel Rate

The GeForce GTX 590 will be quite a bit (more or less 432%) faster with regards to texture filtering than the Radeon R7 240. (explain)

GeForce GTX 590		77696 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 63096 (432%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 590 is a better choice, and very much so. (explain)

GeForce GTX 590		58272 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 52432 (898%)

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 largest amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
