GeForce GTX 750 Ti vs Radeon R9 M380

Intro

Compare all of that to the Radeon R9 M380, which makes use of a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 memory runs at a speed of 1500 MHz on this specific model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M380 should perform a little bit faster than the GeForce GTX 750 Ti in general. (explain)

Radeon R9 M380		96000 MB/sec
GeForce GTX 750 Ti		86400 MB/sec
	Difference: 9600 (11%)

Texel Rate

The GeForce GTX 750 Ti will be a little bit (about 2%) more effective at AF than the Radeon R9 M380. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 800 (2%)

Pixel Rate

The GeForce GTX 750 Ti should be a bit (about 2%) faster with regards to AA than the Radeon R9 M380, and will be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
Radeon R9 M380		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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. 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 faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its 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 the core clock speed. 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
