GeForce GTX 750 Ti vs Radeon R9 M270X

Intro

The GeForce GTX 750 Ti makes use of a 28 nm design. nVidia has clocked the core frequency at 1020 MHz. The GDDR5 memory runs at a speed of 1350 MHz on this particular card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Compare those specs to the Radeon R9 M270X, which features GPU clock speed of 725 MHz, and 2048 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 750 Ti should be a small bit faster than the Radeon R9 M270X in general. (explain)

GeForce GTX 750 Ti 86400 MB/sec
Radeon R9 M270X 72000 MB/sec
Difference: 14400 (20%)

Texel Rate

The GeForce GTX 750 Ti will be much (more or less 41%) faster with regards to anisotropic filtering than the Radeon R9 M270X. (explain)

GeForce GTX 750 Ti 40800 Mtexels/sec
Radeon R9 M270X 29000 Mtexels/sec
Difference: 11800 (41%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 750 Ti is the winner, and very much so. (explain)

GeForce GTX 750 Ti 16320 Mpixels/sec
Radeon R9 M270X 11600 Mpixels/sec
Difference: 4720 (41%)

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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
