GeForce 8600 GS (OEM) vs Radeon R5 M330

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R5 M330 should be 13% faster than the GeForce 8600 GS (OEM) in general, due to its higher bandwidth. (explain)

Radeon R5 M330		14400 MB/sec
GeForce 8600 GS (OEM)		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The Radeon R5 M330 is a lot (approximately 138%) faster with regards to AF than the GeForce 8600 GS (OEM). (explain)

Radeon R5 M330		20600 Mtexels/sec
GeForce 8600 GS (OEM)		8640 Mtexels/sec
	Difference: 11960 (138%)

Pixel Rate

The Radeon R5 M330 will be much (more or less 91%) more effective at FSAA than the GeForce 8600 GS (OEM), and also should be able to handle higher screen resolutions better. (explain)

Radeon R5 M330		8240 Mpixels/sec
GeForce 8600 GS (OEM)		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 max amount of data (counted 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 its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core 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 fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
