GeForce 8500 GT vs Radeon R7 M260

Intro

Compare all of that to the Radeon R7 M260, which comes with GPU clock speed of 715 MHz, and 2048 MB of DDR3 RAM set to run at 1000 MHz through a 64-bit bus. It also features 384 Stream Processors, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M260 should be 25% faster than the GeForce 8500 GT in general, because of its greater data rate. (explain)

Radeon R7 M260		16000 MB/sec
GeForce 8500 GT		12800 MB/sec
	Difference: 3200 (25%)

Texel Rate

The Radeon R7 M260 will be much (approximately 377%) faster with regards to AF than the GeForce 8500 GT. (explain)

Radeon R7 M260		17160 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 13560 (377%)

Pixel Rate

The Radeon R7 M260 should be much (about 218%) better at full screen anti-aliasing than the GeForce 8500 GT, and should be able to handle higher screen resolutions more effectively. (explain)

Radeon R7 M260		5720 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 3920 (218%)

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 largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 are applied per second. This number is worked out by multiplying the total amount of texture units by the core 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 maximum amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
