Geforce GTX 760 vs Radeon R9 270X

Intro

The Geforce GTX 760 has core clock speeds of 980 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 memory. It features 1152 SPUs as well as 96 TAUs and 32 Rasterization Operator Units.

Compare that to the Radeon R9 270X, which comes with GPU core speed of 1000 MHz, and 2048 MB of GDDR5 RAM running at 1400 MHz through a 256-bit bus. It also is comprised of 1280 Stream Processors, 80 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 760 170 Watts
Radeon R9 270X 180 Watts
Difference: 10 Watts (6%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 760 will be 7% faster than the Radeon R9 270X overall, due to its higher bandwidth. (explain)

Geforce GTX 760 192256 MB/sec
Radeon R9 270X 179200 MB/sec
Difference: 13056 (7%)

Texel Rate

The Geforce GTX 760 will be a small bit (about 18%) more effective at texture filtering than the Radeon R9 270X. (explain)

Geforce GTX 760 94080 Mtexels/sec
Radeon R9 270X 80000 Mtexels/sec
Difference: 14080 (18%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 270X is a better choice, not by a very large margin though. (explain)

Radeon R9 270X 32000 Mpixels/sec
Geforce GTX 760 31360 Mpixels/sec
Difference: 640 (2%)

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 data (measured in MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on 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 potential to reach the maximum fill rate.
