GeForce GTX 465 vs Radeon R5 M330

Intro

Compare all of that to the Radeon R5 M330, which comes with core 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 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 465 should be a lot faster than the Radeon R5 M330 in general. (explain)

GeForce GTX 465		102592 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 88192 (612%)

Texel Rate

The GeForce GTX 465 should be quite a bit (more or less 30%) better at texture filtering than the Radeon R5 M330. (explain)

GeForce GTX 465		26708 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 6108 (30%)

Pixel Rate

The GeForce GTX 465 is quite a bit (about 136%) more effective at AA than the Radeon R5 M330, and will be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 11184 (136%)

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 transferred past the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
