Geforce GTX 760 vs Radeon HD 4730

Intro

Compare those specifications to the Radeon HD 4730, which makes use of a 55 nm design. AMD has set the core speed at 700 MHz. The GDDR5 memory runs at a frequency of 900 MHz on this specific card. It features 640(128x5) SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Radeon HD 4730		57600 MB/sec
	Difference: 134656 (234%)

Texel Rate

The Geforce GTX 760 is quite a bit (approximately 320%) more effective at texture filtering than the Radeon HD 4730. (explain)

Geforce GTX 760		94080 Mtexels/sec
Radeon HD 4730		22400 Mtexels/sec
	Difference: 71680 (320%)

Pixel Rate

The Geforce GTX 760 should be much (approximately 460%) better at anti-aliasing than the Radeon HD 4730, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

Geforce GTX 760		31360 Mpixels/sec
Radeon HD 4730		5600 Mpixels/sec
	Difference: 25760 (460%)

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 max amount of data (counted in MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
