GeForce 9600 GSO ASUS 512 vs Radeon R9 M380

Intro

Compare all of that to the Radeon R9 M380, which comes with GPU core speed of 1000 MHz, and 4096 MB of GDDR5 RAM running at 1500 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M380 should in theory perform a lot faster than the GeForce 9600 GSO ASUS 512 in general. (explain)

Radeon R9 M380		96000 MB/sec
GeForce 9600 GSO ASUS 512		16000 MB/sec
	Difference: 80000 (500%)

Texel Rate

The Radeon R9 M380 should be quite a bit (approximately 52%) more effective at anisotropic filtering than the GeForce 9600 GSO ASUS 512. (explain)

Radeon R9 M380		40000 Mtexels/sec
GeForce 9600 GSO ASUS 512		26400 Mtexels/sec
	Difference: 13600 (52%)

Pixel Rate

The Radeon R9 M380 will be a lot (about 142%) better at AA than the GeForce 9600 GSO ASUS 512, and also will be capable of handling higher resolutions without losing too much performance. (explain)

Radeon R9 M380		16000 Mpixels/sec
GeForce 9600 GSO ASUS 512		6600 Mpixels/sec
	Difference: 9400 (142%)

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 (in units of megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
