GeForce 9600 GT 512MB vs Radeon HD 3850 1GB

Intro

The GeForce 9600 GT 512MB comes with a GPU clock speed of 650 MHz, and the 512 MB of GDDR3 memory runs at 900 MHz through a 256-bit bus. It also features 64 Stream Processors, 32 Texture Address Units, and 16 ROPs.

Compare all that to the Radeon HD 3850 1GB, which uses a 55 nm design. AMD has clocked the core speed at 668 MHz. The GDDR3 RAM works at a frequency of 828 MHz on this card. It features 320(64x5) SPUs along with 16 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 3850 1GB 75 Watts
GeForce 9600 GT 512MB 95 Watts
Difference: 20 Watts (27%)

Memory Bandwidth

In theory, the GeForce 9600 GT 512MB is 9% faster than the Radeon HD 3850 1GB overall, due to its higher data rate. (explain)

GeForce 9600 GT 512MB 57600 MB/sec
Radeon HD 3850 1GB 52992 MB/sec
Difference: 4608 (9%)

Texel Rate

The GeForce 9600 GT 512MB should be a lot (more or less 95%) faster with regards to texture filtering than the Radeon HD 3850 1GB. (explain)

GeForce 9600 GT 512MB 20800 Mtexels/sec
Radeon HD 3850 1GB 10688 Mtexels/sec
Difference: 10112 (95%)

Pixel Rate

The Radeon HD 3850 1GB will be just a bit (approximately 3%) more effective at FSAA than the GeForce 9600 GT 512MB, and should be able to handle higher resolutions while still performing well. (explain)

Radeon HD 3850 1GB 10688 Mpixels/sec
GeForce 9600 GT 512MB 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: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
