Radeon HD 5450 vs Radeon R9 Nano

Intro

Compare all that to the Radeon R9 Nano, which features clock speeds of 1000 MHz on the GPU, and 500 MHz on the 4096 MB of HBM memory. It features 4096 SPUs as well as 256 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5450		19 Watts
Radeon R9 Nano		175 Watts
	Difference: 156 Watts (821%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 Nano should be 3900% quicker than the Radeon HD 5450 overall, because of its greater bandwidth. (explain)

Radeon R9 Nano		512000 MB/sec
Radeon HD 5450		12800 MB/sec
	Difference: 499200 (3900%)

Texel Rate

The Radeon R9 Nano is a lot (more or less 4823%) faster with regards to texture filtering than the Radeon HD 5450. (explain)

Radeon R9 Nano		256000 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 250800 (4823%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 Nano is superior to the Radeon HD 5450, and very much so. (explain)

Radeon R9 Nano		64000 Mpixels/sec
Radeon HD 5450		2600 Mpixels/sec
	Difference: 61400 (2362%)

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 (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video 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 maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
