GeForce 8600 GT 256MB GDDR3 vs Radeon R5 M330

Intro

The GeForce 8600 GT 256MB GDDR3 makes use of a 80 nm design. nVidia has clocked the core speed at 540 MHz. The GDDR3 RAM works at a speed of 700 MHz on this model. It features 32 SPUs as well as 16 TAUs and 8 ROPs.

Compare those specifications to the Radeon R5 M330, which features a clock frequency of 1030 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 64-bit memory bus, and makes use of a 28 nm design. It features 320 SPUs, 20 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 8600 GT 256MB GDDR3 should be quite a bit faster than the Radeon R5 M330 overall. (explain)

GeForce 8600 GT 256MB GDDR3 22400 MB/sec
Radeon R5 M330 14400 MB/sec
Difference: 8000 (56%)

Texel Rate

The Radeon R5 M330 should be a lot (approximately 138%) faster with regards to anisotropic filtering than the GeForce 8600 GT 256MB GDDR3. (explain)

Radeon R5 M330 20600 Mtexels/sec
GeForce 8600 GT 256MB GDDR3 8640 Mtexels/sec
Difference: 11960 (138%)

Pixel Rate

The Radeon R5 M330 should be much (more or less 91%) better at full screen anti-aliasing than the GeForce 8600 GT 256MB GDDR3, and will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon R5 M330 8240 Mpixels/sec
GeForce 8600 GT 256MB GDDR3 4320 Mpixels/sec
Difference: 3920 (91%)

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 largest amount of data (counted in MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
