GeForce GT 310 vs Radeon R5 M330

Intro

Compare those specifications to the Radeon R5 M330, which has 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

In theory, the GeForce GT 310 should be a bit faster than the Radeon R5 M330 in general. (explain)

GeForce GT 310		16000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The Radeon R5 M330 should be much (more or less 337%) more effective at texture filtering than the GeForce GT 310. (explain)

Radeon R5 M330		20600 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 15888 (337%)

Pixel Rate

The Radeon R5 M330 will be a lot (about 250%) faster with regards to AA than the GeForce GT 310, and should be capable of handling higher resolutions while still performing well. (explain)

Radeon R5 M330		8240 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 5884 (250%)

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 transferred past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics 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 video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
