GeForce 8500 GT vs Radeon R5 M230

Intro

Compare all of that to the Radeon R5 M230, which features core speeds of 780 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs as well as 20 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R5 M230 should be a lot faster than the GeForce 8500 GT in general. (explain)

Radeon R5 M230		16000 MB/sec
GeForce 8500 GT		12800 MB/sec
	Difference: 3200 (25%)

Texel Rate

The Radeon R5 M230 will be quite a bit (more or less 333%) faster with regards to anisotropic filtering than the GeForce 8500 GT. (explain)

Radeon R5 M230		15600 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 12000 (333%)

Pixel Rate

The Radeon R5 M230 should be quite a bit (approximately 73%) better at AA than the GeForce 8500 GT, and will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon R5 M230		3120 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 1320 (73%)

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 largest amount of data (measured in megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher 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 graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units 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 output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
