GeForce 9800 GTX vs Radeon HD 5550


Intro

The GeForce 9800 GTX has a GPU clock speed of 675 MHz, and the 512 MB of GDDR3 memory is set to run at 1100 MHz through a 256-bit bus. It also is made up of 128 Stream Processors, 64 TAUs, and 16 ROPs.

Compare all that to the Radeon HD 5550, which features GPU core speed of 550 MHz, and 512 MB of DDR2 RAM set to run at 400 MHz through a 128-bit bus. It also is comprised of 320(64x5) Stream Processors, 16 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 9800 GTX should perform much faster than the Radeon HD 5550 in general. (explain)

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

Texel Rate

The GeForce 9800 GTX should be quite a bit (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 should be a lot (more or less 145%) better at full screen anti-aliasing than the Radeon HD 5550, and will be capable of handling 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 maximum amount of information (in units of MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
