GeForce GTX 1050 Ti vs Radeon HD 5450

Intro

Compare all that to the Radeon HD 5450, which makes use of a 40 nm design. AMD has clocked the core frequency at 650 MHz. The DDR3 RAM is set to run at a frequency of 800 MHz on this card. It features 80(16x5) SPUs along with 8 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5450		19 Watts
GeForce GTX 1050 Ti		75 Watts
	Difference: 56 Watts (295%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1050 Ti should be 796% quicker than the Radeon HD 5450 in general, due to its higher bandwidth. (explain)

GeForce GTX 1050 Ti		114688 MB/sec
Radeon HD 5450		12800 MB/sec
	Difference: 101888 (796%)

Texel Rate

The GeForce GTX 1050 Ti will be quite a bit (about 1091%) faster with regards to AF than the Radeon HD 5450. (explain)

GeForce GTX 1050 Ti		61920 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 56720 (1091%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1050 Ti is a better choice, and very much so. (explain)

GeForce GTX 1050 Ti		41280 Mpixels/sec
Radeon HD 5450		2600 Mpixels/sec
	Difference: 38680 (1488%)

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 transferred across the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 most pixels that the graphics chip could possibly record to the local memory per 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 outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
