Geforce GTX 690 vs Radeon RX 470

Intro

The Geforce GTX 690 comes with core clock speeds of 915 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 memory. It features 1536 SPUs along with 128 Texture Address Units and 32 ROPs.

Compare those specifications to the Radeon RX 470, which features a core clock frequency of 926 MHz and a GDDR5 memory frequency of 1650 MHz. It also uses a 256-bit bus, and makes use of a 14 nm design. It features 2048 SPUs, 128 TAUs, and 32 ROPs.

Memory Bandwidth

As far as performance goes, the Geforce GTX 690 should theoretically be quite a bit better than the Radeon RX 470 in general. (explain)

Geforce GTX 690 384512 MB/sec
Radeon RX 470 211200 MB/sec
Difference: 173312 (82%)

Texel Rate

The Geforce GTX 690 will be much (approximately 98%) better at texture filtering than the Radeon RX 470. (explain)

Geforce GTX 690 234240 Mtexels/sec
Radeon RX 470 118528 Mtexels/sec
Difference: 115712 (98%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Geforce GTX 690 is the winner, and very much so. (explain)

Geforce GTX 690 58560 Mpixels/sec
Radeon RX 470 29632 Mpixels/sec
Difference: 28928 (98%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's 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 per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can 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 ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
