GeForce GT 340 vs Radeon R5 M330

Intro

Compare those specifications 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 SPUs, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GT 340 should in theory be much faster than the Radeon R5 M330 in general. (explain)

GeForce GT 340		54400 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 40000 (278%)

Texel Rate

The Radeon R5 M330 should be just a bit (more or less 17%) more effective at AF than the GeForce GT 340. (explain)

Radeon R5 M330		20600 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 3000 (17%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R5 M330 is superior to the GeForce GT 340, by a large margin. (explain)

Radeon R5 M330		8240 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 3840 (87%)

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: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that are processed per second. This is calculated 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
