GeForce 9800 GTX vs GeForce GTX 550 Ti

Intro

The GeForce 9800 GTX has a GPU core speed of 675 MHz, and the 512 MB of GDDR3 RAM is set to run at 1100 MHz through a 256-bit bus. It also is comprised of 128 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.

Compare that to the GeForce GTX 550 Ti, which features core speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 memory. It features 192 SPUs as well as 32 Texture Address Units and 24 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 550 Ti 116 Watts
GeForce 9800 GTX 140 Watts
Difference: 24 Watts (21%)

Memory Bandwidth

Performance-wise, the GeForce GTX 550 Ti should in theory be much superior to the GeForce 9800 GTX in general. (explain)

GeForce GTX 550 Ti 98496 MB/sec
GeForce 9800 GTX 70400 MB/sec
Difference: 28096 (40%)

Texel Rate

The GeForce 9800 GTX should be quite a bit (approximately 50%) better at anisotropic filtering than the GeForce GTX 550 Ti. (explain)

GeForce 9800 GTX 43200 Mtexels/sec
GeForce GTX 550 Ti 28800 Mtexels/sec
Difference: 14400 (50%)

Pixel Rate

The GeForce GTX 550 Ti is a lot (more or less 100%) faster with regards to FSAA than the GeForce 9800 GTX, and capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 550 Ti 21600 Mpixels/sec
GeForce 9800 GTX 10800 Mpixels/sec
Difference: 10800 (100%)

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 largest amount of data (in units of MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units of the card 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.

Quick GPU question says:

[...] sure tbh, so after a quick search i found this. Results surprised me a little if i'm honest.... http://www.hwcompare.com/9783/geforc...ce-gtx-550-ti/ No idea how accurate it is, never seen the site before, but an interesting read i think. [...]
