GeForce 8500 GT vs Radeon R5 M330

Intro

Compare those specs to the Radeon R5 M330, which uses a 28 nm design. AMD has clocked the core frequency at 1030 MHz. The DDR3 memory is set to run at a frequency of 900 MHz on this particular card. It features 320 SPUs along with 20 TAUs and 8 ROPs.

GeForce 8500 GT		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The Radeon R5 M330 is a lot (about 472%) better at AF than the GeForce 8500 GT. (explain)

Radeon R5 M330		20600 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 17000 (472%)

Pixel Rate

The Radeon R5 M330 is much (more or less 358%) better at AA than the GeForce 8500 GT, and also will be able to handle higher screen resolutions more effectively. (explain)

Radeon R5 M330		8240 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 6440 (358%)

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 information (measured in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
