GeForce 8500 GT vs Radeon R5 M330

Intro

The GeForce 8500 GT uses a 80 nm design. nVidia has set the core speed at 450 MHz. The DDR2 memory works at a frequency of 400 MHz on this specific model. It features 16 SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.

Compare those specs to the Radeon R5 M330, which makes use of a 28 nm design. AMD has set the core frequency at 1030 MHz. The DDR3 memory works at a frequency of 900 MHz on this specific model. It features 320 SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R5 M330 should in theory be a small bit superior to the GeForce 8500 GT overall. (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 (about 472%) faster with regards to texture filtering 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 a high resolution 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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 are processed in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
