GeForce 8500 GT vs Radeon R5 M330

Intro

The GeForce 8500 GT has a GPU clock speed of 450 MHz, and the 512 MB of DDR2 memory runs at 400 MHz through a 128-bit bus. It also is made up of 16 Stream Processors, 8 TAUs, and 4 Raster Operation Units.

Compare all that to the Radeon R5 M330, which has core clock speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs along with 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R5 M330 should be a little bit faster than the GeForce 8500 GT in general. (explain)

Radeon R5 M330 14400 MB/sec
GeForce 8500 GT 12800 MB/sec
Difference: 1600 (13%)

Texel Rate

The Radeon R5 M330 should be a lot (approximately 472%) more effective at AF than the GeForce 8500 GT. (explain)

Radeon R5 M330 20600 Mtexels/sec
GeForce 8500 GT 3600 Mtexels/sec
Difference: 17000 (472%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R5 M330 is a better choice, by far. (explain)

Radeon R5 M330 8240 Mpixels/sec
GeForce 8500 GT 1800 Mpixels/sec
Difference: 6440 (358%)

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 information (counted in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, 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 amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at 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 card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
