GeForce GTX 280 vs Radeon RX 470 4GB

Intro

The GeForce GTX 280 uses a 65 nm design. nVidia has clocked the core frequency at 602 MHz. The GDDR3 RAM runs at a speed of 1107 MHz on this particular model. It features 240 SPUs along with 80 Texture Address Units and 32 ROPs.

Compare all that to the Radeon RX 470 4GB, which comes with a core clock frequency of 926 MHz and a GDDR5 memory speed of 1650 MHz. It also makes use of a 256-bit bus, and makes use of a 14 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

GeForce GTX 280 141696 MB/sec
Difference: 69504 (49%)

Texel Rate

The Radeon RX 470 4GB will be much (more or less 146%) more effective at texture filtering than the GeForce GTX 280. (explain)

Radeon RX 470 4GB 118528 Mtexels/sec
GeForce GTX 280 48160 Mtexels/sec
Difference: 70368 (146%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 470 4GB is a better choice, and very much so. (explain)

Radeon RX 470 4GB 29632 Mpixels/sec
GeForce GTX 280 19264 Mpixels/sec
Difference: 10368 (54%)

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 max amount of data (counted in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics 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 most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
