GeForce GT 130 vs Radeon R9 270X

Intro

Compare those specs to the Radeon R9 270X, which has a core clock frequency of 1000 MHz and a GDDR5 memory frequency of 1400 MHz. It also makes use of a 256-bit memory bus, and makes use of a 28 nm design. It is made up of 1280 SPUs, 80 Texture Address Units, and 32 Raster Operation Units.

GeForce GT 130		75 Watts
Radeon R9 270X		180 Watts
	Difference: 105 Watts (140%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 270X should perform quite a bit faster than the GeForce GT 130 overall. (explain)

Radeon R9 270X		179200 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 167200 (1393%)

Texel Rate

The Radeon R9 270X should be quite a bit (about 567%) more effective at texture filtering than the GeForce GT 130. (explain)

Radeon R9 270X		80000 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 68000 (567%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 270X is the winner, and very much so. (explain)

Radeon R9 270X		32000 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 24000 (300%)

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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling 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 chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
