GeForce 8600 GT 1GB DDR2 vs Radeon R5 M330

Intro

Compare all that to the Radeon R5 M330, which makes use of a 28 nm design. AMD has clocked the core speed at 1030 MHz. The DDR3 RAM works at a speed of 900 MHz on this particular card. It features 320 SPUs along with 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R5 M330 should be 13% quicker than the GeForce 8600 GT 1GB DDR2 overall, due to its higher data rate. (explain)

Radeon R5 M330		14400 MB/sec
GeForce 8600 GT 1GB DDR2		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The Radeon R5 M330 should be a lot (more or less 138%) more effective at anisotropic filtering than the GeForce 8600 GT 1GB DDR2. (explain)

Radeon R5 M330		20600 Mtexels/sec
GeForce 8600 GT 1GB DDR2		8640 Mtexels/sec
	Difference: 11960 (138%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R5 M330 is superior to the GeForce 8600 GT 1GB DDR2, by a large margin. (explain)

Radeon R5 M330		8240 Mpixels/sec
GeForce 8600 GT 1GB DDR2		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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 are applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in a 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 - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
