Nvidia Titan X vs Radeon R7 240

Intro

Compare all of that to the Radeon R7 240, which uses a 28 nm design. AMD has clocked the core speed at 730 MHz. The DDR3 RAM runs at a speed of 900 MHz on this card. It features 320 SPUs along with 20 Texture Address Units and 8 Rasterization Operator Units.

	Difference: 220 Watts (733%)

Memory Bandwidth

The Nvidia Titan X should in theory be much faster than the Radeon R7 240 overall. (explain)

Nvidia Titan X		491520 MB/sec
Radeon R7 240		28800 MB/sec
	Difference: 462720 (1607%)

Texel Rate

The Nvidia Titan X should be quite a bit (about 2074%) better at anisotropic filtering than the Radeon R7 240. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 302808 (2074%)

Pixel Rate

The Nvidia Titan X will be a lot (approximately 2229%) more effective at anti-aliasing than the Radeon R7 240, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 130192 (2229%)

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 information (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

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