GeForce GT 310 vs Radeon R5 M330

Intro

Compare those specifications to the Radeon R5 M330, which uses a 28 nm design. AMD has clocked the core frequency at 1030 MHz. The DDR3 memory runs at a frequency of 900 MHz on this particular model. It features 320 SPUs along with 20 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GT 310 should theoretically perform a small bit faster than the Radeon R5 M330 overall. (explain)

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

Texel Rate

The Radeon R5 M330 should be quite a bit (more or less 337%) faster with regards to anisotropic 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 should be much (about 250%) better at full screen anti-aliasing than the GeForce GT 310, and will be able to handle higher screen 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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should 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 anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
