Radeon HD 3470 512MB vs Radeon RX 470 4GB

Intro

Compare all that to the Radeon RX 470 4GB, which has a clock frequency of 926 MHz and a GDDR5 memory frequency of 1650 MHz. It also makes use of a 256-bit bus, and uses a 14 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon RX 470 4GB should in theory be much superior to the Radeon HD 3470 512MB overall. (explain)

Radeon RX 470 4GB		211200 MB/sec
Radeon HD 3470 512MB		30400 MB/sec
	Difference: 180800 (595%)

Texel Rate

The Radeon RX 470 4GB will be a lot (about 3604%) more effective at texture filtering than the Radeon HD 3470 512MB. (explain)

Radeon RX 470 4GB		118528 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 115328 (3604%)

Pixel Rate

The Radeon RX 470 4GB is quite a bit (more or less 826%) more effective at AA than the Radeon HD 3470 512MB, and able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 470 4GB		29632 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 26432 (826%)

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 maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
