GeForce GT 130 vs Radeon R9 M295X

Intro

Compare that to the Radeon R9 M295X, which makes use of a 28 nm design. AMD has clocked the core speed at 750 MHz. The GDDR5 memory is set to run at a frequency of 1375 MHz on this card. It features 2048 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.

GeForce GT 130		75 Watts
Radeon R9 M295X		125 Watts
	Difference: 50 Watts (67%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 M295X is 1367% faster than the GeForce GT 130 overall, due to its higher bandwidth. (explain)

Radeon R9 M295X		176000 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 164000 (1367%)

Texel Rate

The Radeon R9 M295X will be much (more or less 700%) faster with regards to texture filtering than the GeForce GT 130. (explain)

Radeon R9 M295X		96000 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 84000 (700%)

Pixel Rate

The Radeon R9 M295X will be a lot (about 200%) more effective at FSAA than the GeForce GT 130, and should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon R9 M295X		24000 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 16000 (200%)

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 maximum amount of data (counted in MB per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can 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 card's 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
