GeForce 9500 GT 1GB GDDR3 vs Radeon R5 M255

Intro

The GeForce 9500 GT 1GB GDDR3 uses a 55 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR3 memory runs at a frequency of 800 MHz on this model. It features 32 SPUs along with 16 TAUs and 8 ROPs.

Compare those specifications to the Radeon R5 M255, which comes with core speeds of 940 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs along with 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 9500 GT 1GB GDDR3 should in theory be a lot superior to the Radeon R5 M255 overall. (explain)

GeForce 9500 GT 1GB GDDR3 25600 MB/sec
Radeon R5 M255 16000 MB/sec
Difference: 9600 (60%)

Texel Rate

The Radeon R5 M255 will be quite a bit (about 114%) better at AF 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

If using lots of anti-aliasing is important to you, then the Radeon R5 M255 is a better choice, by far. (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 data (in units of MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video 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 Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
