GeForce 9600 GT 1GB vs Radeon R9 M380

Intro

Compare all of that to the Radeon R9 M380, which has GPU clock speed of 1000 MHz, and 4096 MB of GDDR5 RAM running at 1500 MHz through a 128-bit bus. It also features 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M380, in theory, should perform a lot faster than the GeForce 9600 GT 1GB overall. (explain)

Radeon R9 M380		96000 MB/sec
GeForce 9600 GT 1GB		57600 MB/sec
	Difference: 38400 (67%)

Texel Rate

The Radeon R9 M380 will be much (approximately 92%) more effective at anisotropic filtering than the GeForce 9600 GT 1GB. (explain)

Radeon R9 M380		40000 Mtexels/sec
GeForce 9600 GT 1GB		20800 Mtexels/sec
	Difference: 19200 (92%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M380 is a better choice, and very much so. (explain)

Radeon R9 M380		16000 Mpixels/sec
GeForce 9600 GT 1GB		10400 Mpixels/sec
	Difference: 5600 (54%)

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 maximum amount of information (in units of megabytes per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 processed per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, 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 maximum amount 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 worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. 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 rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
