GeForce GTX 260 Core 216 vs Radeon HD 7790

Intro

The GeForce GTX 260 Core 216 has a GPU core clock speed of 576 MHz, and the 896 MB of GDDR3 RAM runs at 999 MHz through a 448-bit bus. It also features 216 SPUs, 72 TAUs, and 28 Raster Operation Units.

Compare all that to the Radeon HD 7790, which comes with clock speeds of 1000 MHz on the GPU, and 1500 MHz on the 1024 MB of GDDR5 memory. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 7790 85 Watts
GeForce GTX 260 Core 216 202 Watts
Difference: 117 Watts (138%)

Memory Bandwidth

In theory, the GeForce GTX 260 Core 216 will be 17% faster than the Radeon HD 7790 overall, because of its higher data rate. (explain)

GeForce GTX 260 Core 216 111888 MB/sec
Radeon HD 7790 96000 MB/sec
Difference: 15888 (17%)

Texel Rate

The Radeon HD 7790 will be quite a bit (approximately 35%) better at anisotropic filtering than the GeForce GTX 260 Core 216. (explain)

Radeon HD 7790 56000 Mtexels/sec
GeForce GTX 260 Core 216 41472 Mtexels/sec
Difference: 14528 (35%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 260 Core 216 is superior to the Radeon HD 7790, not by a very large margin though. (explain)

GeForce GTX 260 Core 216 16128 Mpixels/sec
Radeon HD 7790 16000 Mpixels/sec
Difference: 128 (1%)

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 information (counted in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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