Radeon HD 3470 256MB vs Radeon R9 M365X

Intro

Compare all that to the Radeon R9 M365X, which comes with a core clock frequency of 925 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 ROPs.

Radeon R9 M365X		37000 Mtexels/sec
Radeon HD 3470 256MB		3200 Mtexels/sec
	Difference: 33800 (1056%)

Pixel Rate

The Radeon R9 M365X is quite a bit (about 363%) faster with regards to anti-aliasing than the Radeon HD 3470 256MB, and also will be able to handle higher resolutions without slowing down too much. (explain)

Radeon R9 M365X		14800 Mpixels/sec
Radeon HD 3470 256MB		3200 Mpixels/sec
	Difference: 11600 (363%)

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 largest amount of data (measured in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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