GeForce GTX 260 vs Geforce GTX 770

Intro

Compare all that to the Geforce GTX 770, which has a core clock frequency of 1046 MHz and a GDDR5 memory speed of 1753 MHz. It also uses a 256-bit bus, and uses a 28 nm design. It is made up of 1536 SPUs, 128 Texture Address Units, and 32 ROPs.

GeForce GTX 260		111888 MB/sec
	Difference: 112496 (101%)

Texel Rate

The Geforce GTX 770 is a lot (about 263%) faster with regards to anisotropic filtering than the GeForce GTX 260. (explain)

Geforce GTX 770		133888 Mtexels/sec
GeForce GTX 260		36864 Mtexels/sec
	Difference: 97024 (263%)

Pixel Rate

If running with high levels of AA is important to you, then the Geforce GTX 770 is a better choice, and very much so. (explain)

Geforce GTX 770		33472 Mpixels/sec
GeForce GTX 260		16128 Mpixels/sec
	Difference: 17344 (108%)

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 information (measured in MB per second) that can be transferred over the external memory interface in a second. It's 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 once again. If DDR5, multiply by 4 instead. The higher the 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 number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video 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 card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units 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 rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
