Radeon HD 5750 1GB vs Radeon R9 Nano

Intro

Compare those specs to the Radeon R9 Nano, which has a core clock frequency of 1000 MHz and a HBM memory speed of 500 MHz. It also makes use of a 4096-bit memory bus, and makes use of a 28 nm design. It features 4096 SPUs, 256 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5750 1GB		86 Watts
Radeon R9 Nano		175 Watts
	Difference: 89 Watts (103%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 Nano should be 596% quicker than the Radeon HD 5750 1GB overall, because of its higher bandwidth. (explain)

Radeon R9 Nano		512000 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 438400 (596%)

Texel Rate

The Radeon R9 Nano is quite a bit (more or less 916%) better at anisotropic filtering than the Radeon HD 5750 1GB. (explain)

Radeon R9 Nano		256000 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 230800 (916%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 Nano is a better choice, and very much so. (explain)

Radeon R9 Nano		64000 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 52800 (471%)

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 largest amount of information (in units of MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core 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 rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
