GeForce 9600 GT 1GB vs Radeon HD 4850 2GB

Intro

The GeForce 9600 GT 1GB features a GPU core speed of 650 MHz, and the 1024 MB of GDDR3 RAM is set to run at 900 MHz through a 256-bit bus. It also is made up of 64 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Compare all that to the Radeon HD 4850 2GB, which uses a 55 nm design. AMD has set the core speed at 625 MHz. The GDDR4 memory works at a speed of 993 MHz on this model. It features 800(160x5) SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Radeon HD 4850 2GB 63552 MB/sec
GeForce 9600 GT 1GB 57600 MB/sec
Difference: 5952 (10%)

Texel Rate

The Radeon HD 4850 2GB should be a bit (about 20%) faster with regards to texture filtering than the GeForce 9600 GT 1GB. (explain)

Radeon HD 4850 2GB 25000 Mtexels/sec
GeForce 9600 GT 1GB 20800 Mtexels/sec
Difference: 4200 (20%)

Pixel Rate

The GeForce 9600 GT 1GB should be a small bit (more or less 4%) more effective at AA than the Radeon HD 4850 2GB, and should be able to handle higher screen resolutions better. (explain)

GeForce 9600 GT 1GB 10400 Mpixels/sec
Radeon HD 4850 2GB 10000 Mpixels/sec
Difference: 400 (4%)

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 max amount of data (counted in megabytes per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units 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 per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core 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 many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
