GeForce 8500 GT vs Radeon R5 M330

Intro

Compare all of that to the Radeon R5 M330, which comes with a core clock speed of 1030 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 64-bit bus, and makes use of a 28 nm design. It is comprised of 320 SPUs, 20 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R5 M330 should theoretically perform just a bit faster than 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 should be much (approximately 472%) better at anisotropic 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 using a high screen resolution is important to you, then the Radeon R5 M330 is a better choice, and very much so. (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 maximum amount of data (measured in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. 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 quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
