GeForce GTX 750 vs Radeon R9 M385X

Intro

The GeForce GTX 750 makes use of a 28 nm design. nVidia has clocked the core frequency at 1020 MHz. The GDDR5 memory works at a frequency of 1250 MHz on this card. It features 512 SPUs along with 32 Texture Address Units and 16 ROPs.

Compare those specifications to the Radeon R9 M385X, which makes use of a 28 nm design. AMD has clocked the core frequency at 1100 MHz. The GDDR5 memory is set to run at a frequency of 1500 MHz on this card. It features 896 SPUs along with 56 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M385X, in theory, should perform a small bit faster than the GeForce GTX 750 in general. (explain)

Radeon R9 M385X 96000 MB/sec
GeForce GTX 750 80000 MB/sec
Difference: 16000 (20%)

Texel Rate

The Radeon R9 M385X should be a lot (approximately 89%) more effective at texture filtering than the GeForce GTX 750. (explain)

Radeon R9 M385X 61600 Mtexels/sec
GeForce GTX 750 32640 Mtexels/sec
Difference: 28960 (89%)

Pixel Rate

The Radeon R9 M385X should be a small bit (more or less 8%) faster with regards to AA than the GeForce GTX 750, and also capable of handling higher screen resolutions while still performing well. (explain)

Radeon R9 M385X 17600 Mpixels/sec
GeForce GTX 750 16320 Mpixels/sec
Difference: 1280 (8%)

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 max amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result 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 number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
