GeForce GTX 650 Ti vs Radeon HD 4730

Intro

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

GeForce GTX 650 Ti		110 Watts
Radeon HD 4730		140 Watts
	Difference: 30 Watts (27%)

Memory Bandwidth

Theoretically, the GeForce GTX 650 Ti should perform much faster than the Radeon HD 4730 in general. (explain)

GeForce GTX 650 Ti		86400 MB/sec
Radeon HD 4730		57600 MB/sec
	Difference: 28800 (50%)

Texel Rate

The GeForce GTX 650 Ti will be quite a bit (more or less 165%) more effective at AF than the Radeon HD 4730. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
Radeon HD 4730		22400 Mtexels/sec
	Difference: 36992 (165%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 650 Ti is superior to the Radeon HD 4730, by a large margin. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
Radeon HD 4730		5600 Mpixels/sec
	Difference: 9248 (165%)

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 information (measured in MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 processed in one second. This number is worked out by multiplying the total amount of texture units 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
