GeForce 9800 GT 1GB vs Radeon HD 3850 1GB

Intro

The GeForce 9800 GT 1GB features a GPU clock speed of 600 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 112 Stream Processors, 56 Texture Address Units, and 16 ROPs.

Compare those specifications to the Radeon HD 3850 1GB, which uses a 55 nm design. AMD has set the core speed at 668 MHz. The GDDR3 memory works at a speed of 828 MHz on this model. It features 320(64x5) SPUs as well as 16 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 3850 1GB 75 Watts
GeForce 9800 GT 1GB 105 Watts
Difference: 30 Watts (40%)

Memory Bandwidth

Theoretically speaking, the GeForce 9800 GT 1GB should be 9% faster than the Radeon HD 3850 1GB in general, because of its greater bandwidth. (explain)

GeForce 9800 GT 1GB 57600 MB/sec
Radeon HD 3850 1GB 52992 MB/sec
Difference: 4608 (9%)

Texel Rate

The GeForce 9800 GT 1GB will be a lot (approximately 214%) more effective at anisotropic filtering than the Radeon HD 3850 1GB. (explain)

GeForce 9800 GT 1GB 33600 Mtexels/sec
Radeon HD 3850 1GB 10688 Mtexels/sec
Difference: 22912 (214%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon HD 3850 1GB is the winner, but it probably won't make a huge difference. (explain)

Radeon HD 3850 1GB 10688 Mpixels/sec
GeForce 9800 GT 1GB 9600 Mpixels/sec
Difference: 1088 (11%)

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 max amount of information (counted in megabytes per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock 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 rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
