GeForce GTX 470 vs Radeon R9 M395X

Intro

The GeForce GTX 470 has clock speeds of 607 MHz on the GPU, and 837 MHz on the 1280 MB of GDDR5 memory. It features 448 SPUs along with 56 TAUs and 40 ROPs.

Compare all that to the Radeon R9 M395X, which makes use of a 28 nm design. AMD has clocked the core frequency at 723 MHz. The GDDR5 memory is set to run at a frequency of 1250 MHz on this card. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M395X 125 Watts
GeForce GTX 470 215 Watts
Difference: 90 Watts (72%)

Memory Bandwidth

The Radeon R9 M395X, in theory, should be a small bit faster than the GeForce GTX 470 overall. (explain)

Radeon R9 M395X 160000 MB/sec
GeForce GTX 470 133920 MB/sec
Difference: 26080 (19%)

Texel Rate

The Radeon R9 M395X should be a lot (about 172%) more effective at texture filtering than the GeForce GTX 470. (explain)

Radeon R9 M395X 92544 Mtexels/sec
GeForce GTX 470 33992 Mtexels/sec
Difference: 58552 (172%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 470 is the winner, not by a very large margin though. (explain)

GeForce GTX 470 24280 Mpixels/sec
Radeon R9 M395X 23136 Mpixels/sec
Difference: 1144 (5%)

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: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. 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 rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
