GeForce GTX 295 vs Radeon R9 380 4G

Intro

The GeForce GTX 295 makes use of a 55 nm design. nVidia has set the core frequency at 576 MHz. The GDDR3 memory is set to run at a frequency of 999 MHz on this particular card. It features 240 SPUs as well as 80 Texture Address Units and 28 ROPs.

Compare all that to the Radeon R9 380 4G, which comes with GPU core speed of 970 MHz, and 4096 MB of GDDR5 memory running at 1425 MHz through a 256-bit bus. It also features 1792 SPUs, 112 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 380 4G 190 Watts
GeForce GTX 295 289 Watts
Difference: 99 Watts (52%)

Memory Bandwidth

In theory, the GeForce GTX 295 should be 23% faster than the Radeon R9 380 4G overall, due to its higher data rate. (explain)

GeForce GTX 295 223776 MB/sec
Radeon R9 380 4G 182400 MB/sec
Difference: 41376 (23%)

Texel Rate

The Radeon R9 380 4G is a bit (more or less 18%) faster with regards to texture filtering than the GeForce GTX 295. (explain)

Radeon R9 380 4G 108640 Mtexels/sec
GeForce GTX 295 92160 Mtexels/sec
Difference: 16480 (18%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 295 is the winner, but not by far. (explain)

GeForce GTX 295 32256 Mpixels/sec
Radeon R9 380 4G 31040 Mpixels/sec
Difference: 1216 (4%)

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 MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
