GeForce 9800 GTX vs Radeon HD 7750

Intro

The GeForce 9800 GTX uses a 65 nm design. nVidia has clocked the core frequency at 675 MHz. The GDDR3 RAM is set to run at a speed of 1100 MHz on this specific model. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.

Compare all of that to the Radeon HD 7750, which has GPU core speed of 800 MHz, and 1024 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also features 512 Stream Processors, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 7750 55 Watts
GeForce 9800 GTX 140 Watts
Difference: 85 Watts (155%)

Memory Bandwidth

In theory, the Radeon HD 7750 is 2% faster than the GeForce 9800 GTX in general, due to its higher bandwidth. (explain)

Radeon HD 7750 72000 MB/sec
GeForce 9800 GTX 70400 MB/sec
Difference: 1600 (2%)

Texel Rate

The GeForce 9800 GTX will be quite a bit (about 69%) more effective at anisotropic filtering than the Radeon HD 7750. (explain)

GeForce 9800 GTX 43200 Mtexels/sec
Radeon HD 7750 25600 Mtexels/sec
Difference: 17600 (69%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 7750 is superior to the GeForce 9800 GTX, but only just. (explain)

Radeon HD 7750 12800 Mpixels/sec
GeForce 9800 GTX 10800 Mpixels/sec
Difference: 2000 (19%)

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 data (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
