GeForce 9600 GSO 512MB vs Radeon HD 4850 2GB

Intro

The GeForce 9600 GSO 512MB features a GPU core clock speed of 650 MHz, and the 512 MB of GDDR3 memory is set to run at 900 MHz through a 256-bit bus. It also is made up of 96 SPUs, 48 Texture Address Units, and 16 Raster Operation Units.

Compare those specs to the Radeon HD 4850 2GB, which uses a 55 nm design. AMD has clocked the core speed at 625 MHz. The GDDR4 RAM is set to run at a frequency of 993 MHz on this specific model. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GSO 512MB 90 Watts
Radeon HD 4850 2GB 110 Watts
Difference: 20 Watts (22%)

Memory Bandwidth

In theory, the Radeon HD 4850 2GB will be 10% faster than the GeForce 9600 GSO 512MB overall, due to its higher bandwidth. (explain)

Radeon HD 4850 2GB 63552 MB/sec
GeForce 9600 GSO 512MB 57600 MB/sec
Difference: 5952 (10%)

Texel Rate

The GeForce 9600 GSO 512MB should be a lot (more or less 25%) better at anisotropic filtering than the Radeon HD 4850 2GB. (explain)

GeForce 9600 GSO 512MB 31200 Mtexels/sec
Radeon HD 4850 2GB 25000 Mtexels/sec
Difference: 6200 (25%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce 9600 GSO 512MB is superior to the Radeon HD 4850 2GB, but only just. (explain)

GeForce 9600 GSO 512MB 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: Bandwidth is the largest amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
