GeForce 8500 GT vs Radeon R5 M230

Intro

The GeForce 8500 GT makes use of a 80 nm design. nVidia has set the core speed at 450 MHz. The DDR2 memory works at a frequency of 400 MHz on this particular card. It features 16 SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Compare all that to the Radeon R5 M230, which makes use of a 28 nm design. AMD has clocked the core speed at 780 MHz. The DDR3 RAM works at a frequency of 1000 MHz on this model. It features 320 SPUs as well as 20 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R5 M230 will be 25% quicker than the GeForce 8500 GT in general, due to its greater bandwidth. (explain)

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

Texel Rate

The Radeon R5 M230 is quite a bit (about 333%) better at 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 is much (more or less 73%) faster with regards to full screen anti-aliasing than the GeForce 8500 GT, and will be capable of handling higher screen resolutions better. (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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at handling 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 the graphics card can possibly record 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 clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
