GeForce 8500 GT vs Radeon R5 M255

Intro

The GeForce 8500 GT comes with a core clock speed of 450 MHz and a DDR2 memory speed of 400 MHz. It also features a 128-bit memory bus, and makes use of a 80 nm design. It is comprised of 16 SPUs, 8 Texture Address Units, and 4 ROPs.

Compare those specifications to the Radeon R5 M255, which makes use of a 28 nm design. AMD has set the core speed at 940 MHz. The DDR3 RAM runs at a frequency of 1000 MHz on this model. It features 320 SPUs along with 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R5 M255 should be 25% faster than the GeForce 8500 GT in general, due to its higher data rate. (explain)

Radeon R5 M255 16000 MB/sec
GeForce 8500 GT 12800 MB/sec
Difference: 3200 (25%)

Texel Rate

The Radeon R5 M255 should be a lot (more or less 422%) more effective at anisotropic filtering than the GeForce 8500 GT. (explain)

Radeon R5 M255 18800 Mtexels/sec
GeForce 8500 GT 3600 Mtexels/sec
Difference: 15200 (422%)

Pixel Rate

The Radeon R5 M255 is a lot (more or less 318%) better at full screen anti-aliasing than the GeForce 8500 GT, and also will be capable of handling higher resolutions without slowing down too much. (explain)

Radeon R5 M255 7520 Mpixels/sec
GeForce 8500 GT 1800 Mpixels/sec
Difference: 5720 (318%)

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 largest amount of information (measured in MB per second) that can be moved past the external memory interface in a second. The number is 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 DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video 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 amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core 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 fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
