GeForce GTX 295 vs Radeon R9 380 2G

Intro

The GeForce GTX 295 features a GPU core speed of 576 MHz, and the 896 MB of GDDR3 RAM runs at 999 MHz through a 448-bit bus. It also is made up of 240 Stream Processors, 80 Texture Address Units, and 28 Raster Operation Units.

Compare those specs to the Radeon R9 380 2G, which comes with clock speeds of 970 MHz on the GPU, and 1425 MHz on the 2048 MB of GDDR5 memory. It features 1792 SPUs along with 112 TAUs and 32 Rasterization Operator Units.

Radeon R9 380 2G 182400 MB/sec
Difference: 41376 (23%)

Texel Rate

The Radeon R9 380 2G should be a little bit (more or less 18%) more effective at texture filtering than the GeForce GTX 295. (explain)

Radeon R9 380 2G 108640 Mtexels/sec
GeForce GTX 295 92160 Mtexels/sec
Difference: 16480 (18%)

Pixel Rate

The GeForce GTX 295 will be a bit (more or less 4%) more effective at anti-aliasing than the Radeon R9 380 2G, and capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 295 32256 Mpixels/sec
Radeon R9 380 2G 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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be moved across 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 it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are 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 higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units 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 output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
