GeForce 9500 GT 1GB GDDR3 vs Radeon R5 M255

Intro

The GeForce 9500 GT 1GB GDDR3 features clock speeds of 550 MHz on the GPU, and 800 MHz on the 1024 MB of GDDR3 RAM. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Compare all that to the Radeon R5 M255, which comes with a clock speed of 940 MHz and a DDR3 memory speed of 1000 MHz. It also uses a 64-bit bus, and uses a 28 nm design. It is comprised of 320 SPUs, 20 Texture Address Units, and 8 Raster Operation Units.

Radeon R5 M255 16000 MB/sec
Difference: 9600 (60%)

Texel Rate

The Radeon R5 M255 should be much (more or less 114%) more effective at anisotropic filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

Radeon R5 M255 18800 Mtexels/sec
GeForce 9500 GT 1GB GDDR3 8800 Mtexels/sec
Difference: 10000 (114%)

Pixel Rate

The Radeon R5 M255 should be a lot (about 71%) better at AA than the GeForce 9500 GT 1GB GDDR3, and also should be able to handle higher screen resolutions while still performing well. (explain)

Radeon R5 M255 7520 Mpixels/sec
GeForce 9500 GT 1GB GDDR3 4400 Mpixels/sec
Difference: 3120 (71%)

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 (in units of megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few 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.
