GeForce GTX 650 Ti 2GB vs Radeon R9 M380

Intro

Compare those specifications to the Radeon R9 M380, which features a GPU core clock speed of 1000 MHz, and 4096 MB of GDDR5 RAM set to run at 1500 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M380 should theoretically be a small bit faster than the GeForce GTX 650 Ti 2GB in general. (explain)

Radeon R9 M380		96000 MB/sec
GeForce GTX 650 Ti 2GB		86400 MB/sec
	Difference: 9600 (11%)

Texel Rate

The GeForce GTX 650 Ti 2GB will be much (more or less 48%) faster with regards to anisotropic filtering than the Radeon R9 M380. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 19392 (48%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M380 is the winner, but it probably won't make a huge difference. (explain)

Radeon R9 M380		16000 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 1152 (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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
