GeForce GT 130 vs Geforce GTX 770

Intro

Compare those specifications to the Geforce GTX 770, which has a clock frequency of 1046 MHz and a GDDR5 memory frequency of 1753 MHz. It also uses a 256-bit memory bus, and makes use of a 28 nm design. It features 1536 SPUs, 128 TAUs, and 32 Raster Operation Units.

GeForce GT 130		75 Watts
Geforce GTX 770		230 Watts
	Difference: 155 Watts (207%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 770 should perform quite a bit faster than the GeForce GT 130 overall. (explain)

Geforce GTX 770		224384 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 212384 (1770%)

Texel Rate

The Geforce GTX 770 is quite a bit (approximately 1016%) faster with regards to texture filtering than the GeForce GT 130. (explain)

Geforce GTX 770		133888 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 121888 (1016%)

Pixel Rate

If using high levels of AA is important to you, then the Geforce GTX 770 is the winner, by far. (explain)

Geforce GTX 770		33472 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 25472 (318%)

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 (in units of MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant 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 maximum fill rate.
