GeForce 9800 GTX vs Radeon HD 5550

Intro

The GeForce 9800 GTX has core clock speeds of 675 MHz on the GPU, and 1100 MHz on the 512 MB of GDDR3 RAM. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Compare those specifications to the Radeon HD 5550, which makes use of a 40 nm design. AMD has clocked the core speed at 550 MHz. The DDR2 RAM is set to run at a speed of 400 MHz on this card. It features 320(64x5) SPUs along with 16 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 9800 GTX should be 450% faster than the Radeon HD 5550 in general, because of its greater bandwidth. (explain)

GeForce 9800 GTX 70400 MB/sec
Radeon HD 5550 12800 MB/sec
Difference: 57600 (450%)

Texel Rate

The GeForce 9800 GTX will be a lot (approximately 391%) more effective at AF than the Radeon HD 5550. (explain)

GeForce 9800 GTX 43200 Mtexels/sec
Radeon HD 5550 8800 Mtexels/sec
Difference: 34400 (391%)

Pixel Rate

The GeForce 9800 GTX is much (approximately 145%) more effective at AA than the Radeon HD 5550, and will be able to handle higher resolutions without losing too much performance. (explain)

GeForce 9800 GTX 10800 Mpixels/sec
Radeon HD 5550 4400 Mpixels/sec
Difference: 6400 (145%)

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 max amount of data (measured in MB per second) that can be transferred past 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 memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 are applied per second. This figure is calculated by multiplying the total number of texture units by the core 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 applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
