Geforce GTX 670 vs Radeon R5 M330

Intro

Compare that to the Radeon R5 M330, which features core speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Geforce GTX 670 should be 1233% quicker than the Radeon R5 M330 overall, because of its greater data rate. (explain)

Geforce GTX 670		192000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 177600 (1233%)

Texel Rate

The Geforce GTX 670 should be quite a bit (approximately 397%) faster with regards to anisotropic filtering than the Radeon R5 M330. (explain)

Geforce GTX 670		102480 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 81880 (397%)

Pixel Rate

The Geforce GTX 670 will be much (about 255%) faster with regards to anti-aliasing than the Radeon R5 M330, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

Geforce GTX 670		29280 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 21040 (255%)

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 largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many 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.
