GeForce 9600 GT 1GB vs Radeon HD 4770

Intro

The GeForce 9600 GT 1GB makes use of a 65/55 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR3 memory runs at a speed of 900 MHz on this particular card. It features 64 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Compare those specifications to the Radeon HD 4770, which has core speeds of 750 MHz on the GPU, and 800 MHz on the 512 MB of GDDR5 RAM. It features 640(128x5) SPUs as well as 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4770 80 Watts
GeForce 9600 GT 1GB 95 Watts
Difference: 15 Watts (19%)

Memory Bandwidth

Theoretically speaking, the GeForce 9600 GT 1GB will be 13% quicker than the Radeon HD 4770 in general, due to its greater bandwidth. (explain)

GeForce 9600 GT 1GB 57600 MB/sec
Radeon HD 4770 51200 MB/sec
Difference: 6400 (13%)

Texel Rate

The Radeon HD 4770 should be a bit (approximately 15%) more effective at anisotropic filtering than the GeForce 9600 GT 1GB. (explain)

Radeon HD 4770 24000 Mtexels/sec
GeForce 9600 GT 1GB 20800 Mtexels/sec
Difference: 3200 (15%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 4770 is a better choice, though not by far. (explain)

Radeon HD 4770 12000 Mpixels/sec
GeForce 9600 GT 1GB 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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its 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 filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
