GeForce 8500 GT vs Radeon R5 M330

Intro

Compare all that to the Radeon R5 M330, which comes with clock speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R5 M330 should theoretically be a bit superior to the GeForce 8500 GT overall. (explain)

Radeon R5 M330		14400 MB/sec
GeForce 8500 GT		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The Radeon R5 M330 will be much (approximately 472%) more effective at texture filtering than the GeForce 8500 GT. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R5 M330 is the winner, by far. (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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units of the card 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
