GeForce GT 130 vs Radeon R7 250X 2GB

Intro

Compare those specifications to the Radeon R7 250X 2GB, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 RAM is set to run at a frequency of 1125 MHz on this model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

GeForce GT 130		12000 MB/sec
	Difference: 60000 (500%)

Texel Rate

The Radeon R7 250X 2GB will be much (more or less 233%) more effective at AF than the GeForce GT 130. (explain)

Radeon R7 250X 2GB		40000 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 28000 (233%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R7 250X 2GB is the winner, and very much so. (explain)

Radeon R7 250X 2GB		16000 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 8000 (100%)

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 maximum amount of data (counted in MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
