GeForce 9600 GSO 512MB vs Radeon HD 4830 1GB

Intro

The GeForce 9600 GSO 512MB comes with a GPU core speed of 650 MHz, and the 512 MB of GDDR3 memory runs at 900 MHz through a 256-bit bus. It also features 96 Stream Processors, 48 Texture Address Units, and 16 Raster Operation Units.

Compare those specs to the Radeon HD 4830 1GB, which features clock speeds of 575 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR4 RAM. It features 640(128x5) SPUs along with 32 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 4830 1GB 95 Watts
Difference: 5 Watts (6%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

The GeForce 9600 GSO 512MB is much (approximately 70%) better at AF than the Radeon HD 4830 1GB. (explain)

GeForce 9600 GSO 512MB 31200 Mtexels/sec
Radeon HD 4830 1GB 18400 Mtexels/sec
Difference: 12800 (70%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 9600 GSO 512MB is the winner, not by a very large margin though. (explain)

GeForce 9600 GSO 512MB 10400 Mpixels/sec
Radeon HD 4830 1GB 9200 Mpixels/sec
Difference: 1200 (13%)

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 (measured in megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out 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 in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
