GeForce 9600 GT 512MB vs Radeon HD 4770

Intro

The GeForce 9600 GT 512MB comes with a core clock speed of 650 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 256-bit memory bus, and uses a 65/55 nm design. It is made up of 64 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Compare those specifications to the Radeon HD 4770, which makes use of a 40 nm design. AMD has set the core speed at 750 MHz. The GDDR5 memory runs at a frequency of 800 MHz on this card. It features 640(128x5) SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4770 80 Watts
GeForce 9600 GT 512MB 95 Watts
Difference: 15 Watts (19%)

Memory Bandwidth

In theory, the GeForce 9600 GT 512MB should be just a bit faster than the Radeon HD 4770 overall. (explain)

GeForce 9600 GT 512MB 57600 MB/sec
Radeon HD 4770 51200 MB/sec
Difference: 6400 (13%)

Texel Rate

The Radeon HD 4770 should be a little bit (more or less 15%) better at texture filtering than the GeForce 9600 GT 512MB. (explain)

Radeon HD 4770 24000 Mtexels/sec
GeForce 9600 GT 512MB 20800 Mtexels/sec
Difference: 3200 (15%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 4770 is a better choice, not by a very large margin though. (explain)

Radeon HD 4770 12000 Mpixels/sec
GeForce 9600 GT 512MB 10400 Mpixels/sec
Difference: 1600 (15%)

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: Bandwidth is the largest amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video 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 most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
