GeForce 8800 GT 1GB vs Radeon R9 M365X

Intro

Compare that to the Radeon R9 M365X, which features GPU clock speed of 925 MHz, and 4096 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, 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 is a bit (about 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

If using a high resolution 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 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: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher 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 maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour 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 output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
