GeForce GT 310 vs Radeon R9 M385X

Intro

Compare all of that to the Radeon R9 M385X, which features a core clock speed of 1100 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M385X should be 500% faster than the GeForce GT 310 overall, because of its higher data rate. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 80000 (500%)

Texel Rate

The Radeon R9 M385X is a lot (more or less 1207%) faster with regards to AF than the GeForce GT 310. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 56888 (1207%)

Pixel Rate

The Radeon R9 M385X will be much (more or less 647%) better at anti-aliasing than the GeForce GT 310, and also will be able to handle higher resolutions without losing too much performance. (explain)

Radeon R9 M385X		17600 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 15244 (647%)

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 moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could 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 colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
