GeForce 810M vs Radeon HD 5450

Intro

Compare those specifications to the Radeon HD 5450, which features a clock speed of 650 MHz and a DDR3 memory frequency of 800 MHz. It also makes use of a 64-bit bus, and makes use of a 40 nm design. It is made up of 80(16x5) SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce 810M should be 13% quicker than the Radeon HD 5450 overall, due to its greater data rate. (explain)

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

Texel Rate

The GeForce 810M should be a little bit (more or less 14%) better at anisotropic filtering 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 is a little bit (more or less 14%) faster with regards to FSAA than the Radeon HD 5450, and should be capable of handling higher resolutions without losing too much performance. (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 maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core clock 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few 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.
