GeForce GTX 650 Ti 2GB vs Radeon R7 250

Intro

Compare those specifications to the Radeon R7 250, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 memory is set to run at a frequency of 1150 MHz on this particular model. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Radeon R7 250		24000 Mtexels/sec
	Difference: 35392 (147%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 650 Ti 2GB is a better choice, and very much so. (explain)

GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
Radeon R7 250		8000 Mpixels/sec
	Difference: 6848 (86%)

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 max amount of data (measured in megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better 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 maximum amount of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 get to the maximum fill rate.
