GeForce GTX 750 Ti vs Radeon R7 250X 2GB

Intro

The GeForce GTX 750 Ti comes with a GPU clock speed of 1020 MHz, and the 2048 MB of GDDR5 memory is set to run at 1350 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Compare those specifications to the Radeon R7 250X 2GB, which features a core clock speed of 1000 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti 60 Watts
Radeon R7 250X 2GB 95 Watts
Difference: 35 Watts (58%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 750 Ti should be 20% faster than the Radeon R7 250X 2GB in general, because of its higher data rate. (explain)

GeForce GTX 750 Ti 86400 MB/sec
Radeon R7 250X 2GB 72000 MB/sec
Difference: 14400 (20%)

Texel Rate

The GeForce GTX 750 Ti is a bit (more or less 2%) faster with regards to texture filtering than the Radeon R7 250X 2GB. (explain)

GeForce GTX 750 Ti 40800 Mtexels/sec
Radeon R7 250X 2GB 40000 Mtexels/sec
Difference: 800 (2%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 750 Ti is the winner, though only just barely. (explain)

GeForce GTX 750 Ti 16320 Mpixels/sec
Radeon R7 250X 2GB 16000 Mpixels/sec
Difference: 320 (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 largest amount of information (counted in MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, 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 chip could possibly record to the local memory in one 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 filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
