GeForce GTX 460 2GB vs Radeon R5 M330

Intro

Compare all of that to the Radeon R5 M330, which comes with clock speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 460 2GB, in theory, should be quite a bit faster than the Radeon R5 M330 overall. (explain)

GeForce GTX 460 2GB		115200 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 100800 (700%)

Texel Rate

The GeForce GTX 460 2GB will be much (about 83%) more effective at anisotropic filtering than the Radeon R5 M330. (explain)

GeForce GTX 460 2GB		37800 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 17200 (83%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 460 2GB is the winner, by far. (explain)

GeForce GTX 460 2GB		21600 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 13360 (162%)

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 (measured in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount 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 worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
