GeForce 8500 GT vs Radeon R5 M230

Intro

The GeForce 8500 GT comes with a GPU core clock speed of 450 MHz, and the 512 MB of DDR2 RAM is set to run at 400 MHz through a 128-bit bus. It also is comprised of 16 SPUs, 8 Texture Address Units, and 4 ROPs.

Compare all that to the Radeon R5 M230, which has core speeds of 780 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs along with 20 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R5 M230 will be 25% faster than the GeForce 8500 GT overall, due to its greater data rate. (explain)

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

Texel Rate

The Radeon R5 M230 should be a lot (approximately 333%) better at AF than the GeForce 8500 GT. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R5 M230 is the winner, and very much so. (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: Bandwidth is the max amount of information (counted in MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 number is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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