GeForce 8800 GT 512MB vs Radeon R9 M365X

Intro

Compare all that to the Radeon R9 M365X, which features GPU core speed of 925 MHz, and 4096 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M365X should in theory be quite a bit superior to the GeForce 8800 GT 512MB overall. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The Radeon R9 M365X is just a bit (approximately 10%) better at anisotropic filtering than the GeForce 8800 GT 512MB. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 3400 (10%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M365X is a better choice, by far. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 5200 (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 max amount of information (counted in megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card 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 amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
