GeForce GTX Titan X vs Radeon R9 280X

Intro

The GeForce GTX Titan X uses a 28 nm design. nVidia has set the core speed at 1000 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this specific model. It features 3072 SPUs as well as 192 Texture Address Units and 96 Rasterization Operator Units.

Compare those specs to the Radeon R9 280X, which has core clock speeds of 850 MHz on the GPU, and 1500 MHz on the 3072 MB of GDDR5 memory. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

Radeon R9 280X 288000 MB/sec
Difference: 48000 (17%)

Texel Rate

The GeForce GTX Titan X should be quite a bit (approximately 76%) more effective at AF than the Radeon R9 280X. (explain)

GeForce GTX Titan X 192000 Mtexels/sec
Radeon R9 280X 108800 Mtexels/sec
Difference: 83200 (76%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX Titan X is the winner, by a large margin. (explain)

GeForce GTX Titan X 96000 Mpixels/sec
Radeon R9 280X 27200 Mpixels/sec
Difference: 68800 (253%)

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 transferred past the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
