GeForce GTX 260 Core 216 vs Geforce GTX 770

Intro

Compare those specs to the Geforce GTX 770, which features GPU clock speed of 1046 MHz, and 2048 MB of GDDR5 memory set to run at 1753 MHz through a 256-bit bus. It also is comprised of 1536 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 260 Core 216		202 Watts
Geforce GTX 770		230 Watts
	Difference: 28 Watts (14%)

Memory Bandwidth

In theory, the Geforce GTX 770 will be 101% faster than the GeForce GTX 260 Core 216 in general, because of its higher data rate. (explain)

Geforce GTX 770		224384 MB/sec
GeForce GTX 260 Core 216		111888 MB/sec
	Difference: 112496 (101%)

Texel Rate

The Geforce GTX 770 should be quite a bit (more or less 223%) better at texture filtering than the GeForce GTX 260 Core 216. (explain)

Geforce GTX 770		133888 Mtexels/sec
GeForce GTX 260 Core 216		41472 Mtexels/sec
	Difference: 92416 (223%)

Pixel Rate

If using a high resolution 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 Core 216		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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's 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 amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in a 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 - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
