GeForce GT 320 vs Radeon R5 M230

Intro

Compare all that to the Radeon R5 M230, which has a core clock speed of 780 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 64-bit memory bus, and uses a 28 nm design. It is made up of 320 SPUs, 20 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GT 320 should in theory be quite a bit superior to the Radeon R5 M230 overall. (explain)

GeForce GT 320		25280 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 9280 (58%)

Texel Rate

The Radeon R5 M230 should be a little bit (about 20%) better at texture filtering than the GeForce GT 320. (explain)

Radeon R5 M230		15600 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 2640 (20%)

Pixel Rate

The GeForce GT 320 will be a lot (more or less 38%) better at anti-aliasing than the Radeon R5 M230, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GT 320		4320 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 1200 (38%)

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 (in units of MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
