Geforce GTX 770 vs Radeon HD 5750 1GB

Intro

Compare all of that to the Radeon HD 5750 1GB, which has GPU core speed of 700 MHz, and 1024 MB of GDDR5 RAM set to run at 1150 MHz through a 128-bit bus. It also is comprised of 720(144x5) SPUs, 36 Texture Address Units, and 16 ROPs.

Theoretically speaking, the Geforce GTX 770 should be 205% faster than the Radeon HD 5750 1GB overall, because of its higher bandwidth. (explain)

Geforce GTX 770		224384 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 150784 (205%)

Texel Rate

The Geforce GTX 770 is much (approximately 431%) more effective at texture filtering than the Radeon HD 5750 1GB. (explain)

Geforce GTX 770		133888 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 108688 (431%)

Pixel Rate

The Geforce GTX 770 should be much (more or less 199%) more effective at FSAA than the Radeon HD 5750 1GB, and also able to handle higher resolutions without slowing down too much. (explain)

Geforce GTX 770		33472 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 22272 (199%)

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 (measured in MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
