GeForce 8800 GTS (G92) vs Radeon R5 M330

Intro

Compare all of that to the Radeon R5 M330, which features GPU clock speed of 1030 MHz, and 2048 MB of DDR3 RAM running at 900 MHz through a 64-bit bus. It also is made up of 320 Stream Processors, 20 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 8800 GTS (G92) should in theory be a lot better than the Radeon R5 M330 in general. (explain)

GeForce 8800 GTS (G92)		62080 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 47680 (331%)

Texel Rate

The GeForce 8800 GTS (G92) should be a lot (about 102%) more effective at anisotropic filtering than the Radeon R5 M330. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 21000 (102%)

Pixel Rate

The GeForce 8800 GTS (G92) will be quite a bit (more or less 26%) faster with regards to FSAA than the Radeon R5 M330, and capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce 8800 GTS (G92)		10400 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 2160 (26%)

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 data (in units of MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should 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, High Dynamic Range 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 worked out by multiplying the total amount of texture units 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
