GeForce GT 340 1GB vs Radeon R5 M330

Intro

Compare those specifications to the Radeon R5 M330, which features GPU core speed of 1030 MHz, and 2048 MB of DDR3 memory set to run at 900 MHz through a 64-bit bus. It also is made up of 320 Stream Processors, 20 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 340 1GB should perform much faster than the Radeon R5 M330 overall. (explain)

GeForce GT 340 1GB		54400 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 40000 (278%)

Texel Rate

The Radeon R5 M330 is a bit (about 17%) better at anisotropic filtering than the GeForce GT 340 1GB. (explain)

Radeon R5 M330		20600 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 3000 (17%)

Pixel Rate

The Radeon R5 M330 will be quite a bit (more or less 87%) more effective at full screen anti-aliasing than the GeForce GT 340 1GB, and also will be able to handle higher screen resolutions better. (explain)

Radeon R5 M330		8240 Mpixels/sec
GeForce GT 340 1GB		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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
