GeForce GTX 295 vs Radeon R9 M380

Intro

The GeForce GTX 295 has a GPU clock speed of 576 MHz, and the 896 MB of GDDR3 memory is set to run at 999 MHz through a 448-bit bus. It also features 240 SPUs, 80 TAUs, and 28 ROPs.

Compare all of that to the Radeon R9 M380, which comes with core clock speeds of 1000 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTX 295 should perform a lot faster than the Radeon R9 M380 overall. (explain)

GeForce GTX 295 223776 MB/sec
Radeon R9 M380 96000 MB/sec
Difference: 127776 (133%)

Texel Rate

The GeForce GTX 295 should be quite a bit (approximately 130%) better at anisotropic filtering than the Radeon R9 M380. (explain)

GeForce GTX 295 92160 Mtexels/sec
Radeon R9 M380 40000 Mtexels/sec
Difference: 52160 (130%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 295 is the winner, and very much so. (explain)

GeForce GTX 295 32256 Mpixels/sec
Radeon R9 M380 16000 Mpixels/sec
Difference: 16256 (102%)

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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If 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, 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 is calculated by multiplying the total number of texture units of the card by the core clock 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
