GeForce 8500 GT vs Radeon R9 M365X

Intro

Compare those specifications to the Radeon R9 M365X, which comes with a GPU core 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 comprised of 640 Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M365X should perform a lot faster than the GeForce 8500 GT overall. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce 8500 GT		12800 MB/sec
	Difference: 59200 (463%)

Texel Rate

The Radeon R9 M365X will be quite a bit (approximately 928%) better at texture filtering than the GeForce 8500 GT. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 33400 (928%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M365X is a better choice, and very much so. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 13000 (722%)

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 information (counted in megabytes per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once 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, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
