Geforce GTX 760 vs Radeon HD 4670 1GB

Intro

Compare those specifications to the Radeon HD 4670 1GB, which uses a 55 nm design. AMD has set the core frequency at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 memory works at a speed of 1100 MHz on this card. It features 320(64x5) SPUs along with 32 TAUs and 8 Rasterization Operator Units.

Radeon HD 4670 1GB		24000 Mtexels/sec
	Difference: 70080 (292%)

Pixel Rate

If running with a high screen resolution is important to you, then the Geforce GTX 760 is superior to the Radeon HD 4670 1GB, and very much so. (explain)

Geforce GTX 760		31360 Mpixels/sec
Radeon HD 4670 1GB		6000 Mpixels/sec
	Difference: 25360 (423%)

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 largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, 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 amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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.
