Radeon HD 4730 vs Radeon HD 7750

Intro

The Radeon HD 4730 features a GPU core speed of 700 MHz, and the 512 MB of GDDR5 RAM runs at 900 MHz through a 128-bit bus. It also is made up of 640(128x5) Stream Processors, 32 Texture Address Units, and 8 ROPs.

Compare those specs to the Radeon HD 7750, which features a clock frequency of 800 MHz and a GDDR5 memory frequency of 1125 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is comprised of 512 SPUs, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 7750 55 Watts
Radeon HD 4730 140 Watts
Difference: 85 Watts (155%)

Memory Bandwidth

In theory, the Radeon HD 7750 should perform quite a bit faster than the Radeon HD 4730 overall. (explain)

Radeon HD 7750 72000 MB/sec
Radeon HD 4730 57600 MB/sec
Difference: 14400 (25%)

Texel Rate

The Radeon HD 7750 is a little bit (approximately 14%) more effective at AF than the Radeon HD 4730. (explain)

Radeon HD 7750 25600 Mtexels/sec
Radeon HD 4730 22400 Mtexels/sec
Difference: 3200 (14%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 7750 is the winner, and very much so. (explain)

Radeon HD 7750 12800 Mpixels/sec
Radeon HD 4730 5600 Mpixels/sec
Difference: 7200 (129%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
