GeForce 9600 GT 1GB vs Radeon HD 6950


Intro

The GeForce 9600 GT 1GB uses a 65/55 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this particular model. It features 64 SPUs as well as 32 Texture Address Units and 16 ROPs.

Compare that to the Radeon HD 6950, which features a GPU core clock speed of 800 MHz, and 1024 MB of GDDR5 RAM set to run at 1250 MHz through a 256-bit bus. It also is comprised of 1408 Stream Processors, 88 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GT 1GB 95 Watts
Radeon HD 6950 200 Watts
Difference: 105 Watts (111%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6950 should be 178% quicker than the GeForce 9600 GT 1GB in general, because of its greater bandwidth. (explain)

Radeon HD 6950 160000 MB/sec
GeForce 9600 GT 1GB 57600 MB/sec
Difference: 102400 (178%)

Texel Rate

The Radeon HD 6950 will be quite a bit (approximately 238%) faster with regards to AF than the GeForce 9600 GT 1GB. (explain)

Radeon HD 6950 70400 Mtexels/sec
GeForce 9600 GT 1GB 20800 Mtexels/sec
Difference: 49600 (238%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 6950 is a better choice, by far. (explain)

Radeon HD 6950 25600 Mpixels/sec
GeForce 9600 GT 1GB 10400 Mpixels/sec
Difference: 15200 (146%)

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 maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 are processed per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
