GeForce GT 340 vs Radeon R5 M330

Intro

Compare all that to the Radeon R5 M330, which has core clock speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs along with 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GT 340 should theoretically perform 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 is a small bit (more or less 17%) better at texture filtering 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 a high resolution is important to you, then the Radeon R5 M330 is superior to the GeForce GT 340, and very much so. (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 information (measured in MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units by the core clock 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 one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
