GeForce 9600 GSO ASUS 512 vs Radeon HD 4650 512MB

Intro

The GeForce 9600 GSO ASUS 512 features a core clock speed of 550 MHz and a DDR2 memory frequency of 500 MHz. It also uses a 128-bit memory bus, and makes use of a 65 nm design. It is comprised of 96 SPUs, 48 TAUs, and 12 Raster Operation Units.

Compare that to the Radeon HD 4650 512MB, which features a GPU core clock speed of 600 MHz, and 512 MB of DDR2 memory set to run at 500 MHz through a 128-bit bus. It also features 320(64x5) Stream Processors, 32 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4650 512MB 55 Watts
GeForce 9600 GSO ASUS 512 84 Watts
Difference: 29 Watts (53%)

Memory Bandwidth

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

Texel Rate

The GeForce 9600 GSO ASUS 512 should be quite a bit (approximately 38%) faster with regards to AF than the Radeon HD 4650 512MB. (explain)

GeForce 9600 GSO ASUS 512 26400 Mtexels/sec
Radeon HD 4650 512MB 19200 Mtexels/sec
Difference: 7200 (38%)

Pixel Rate

The GeForce 9600 GSO ASUS 512 should be much (more or less 38%) more effective at anti-aliasing than the Radeon HD 4650 512MB, and also should be capable of handling higher resolutions more effectively. (explain)

GeForce 9600 GSO ASUS 512 6600 Mpixels/sec
Radeon HD 4650 512MB 4800 Mpixels/sec
Difference: 1800 (38%)

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 maximum amount of information (measured in MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number 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 number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
