GeForce 8800 GT 1GB vs Radeon R9 M365X

Intro

Compare all that to the Radeon R9 M365X, which features clock speeds of 925 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M365X should perform quite a bit faster than the GeForce 8800 GT 1GB in general. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The Radeon R9 M365X will be a little bit (more or less 10%) better at AF than the GeForce 8800 GT 1GB. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 3400 (10%)

Pixel Rate

The Radeon R9 M365X will be a lot (approximately 54%) more effective at full screen anti-aliasing than the GeForce 8800 GT 1GB, and will be able to handle higher screen resolutions more effectively. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce 8800 GT 1GB		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 maximum amount of information (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses 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 texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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