VS

GeForce 9600 GT 1GB vs Radeon HD 3850 256MB

Intro

The GeForce 9600 GT 1GB has core speeds of 650 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 RAM. It features 64 SPUs along with 32 TAUs and 16 ROPs.

Compare those specs to the Radeon HD 3850 256MB, which comes with GPU clock speed of 668 MHz, and 256 MB of GDDR3 RAM running at 828 MHz through a 256-bit bus. It also is made up of 320(64x5) SPUs, 16 Texture Address Units, and 16 Raster Operation Units.

The GeForce 9600 GT 1GB will be much (about 95%) more effective at anisotropic filtering than the Radeon HD 3850 256MB. (explain)

GeForce 9600 GT 1GB 20800 Mtexels/sec
Radeon HD 3850 256MB 10688 Mtexels/sec
Difference: 10112 (95%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 3850 256MB is the winner, though only just barely. (explain)

Radeon HD 3850 256MB 10688 Mpixels/sec
GeForce 9600 GT 1GB 10400 Mpixels/sec
Difference: 288 (3%)

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 (counted in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
