GeForce 810M vs Radeon HD 5450

Intro

Compare all of 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 model. It features 80(16x5) SPUs as well as 8 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
Radeon HD 5450		19 Watts
	Difference: 4 Watts (27%)

Memory Bandwidth

In theory, the GeForce 810M should perform just a bit faster than the Radeon HD 5450 in general. (explain)

GeForce 810M		14400 MB/sec
Radeon HD 5450		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The GeForce 810M should be a small bit (approximately 14%) more effective at AF than the Radeon HD 5450. (explain)

GeForce 810M		5904 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 704 (14%)

Pixel Rate

The GeForce 810M should be a bit (more or less 14%) faster with regards to full screen anti-aliasing than the Radeon HD 5450, and also capable of handling higher resolutions without slowing down too much. (explain)

GeForce 810M		2952 Mpixels/sec
Radeon HD 5450		2600 Mpixels/sec
	Difference: 352 (14%)

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 MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
