GeForce GTX 950M vs Radeon HD 5450

Intro

Compare all of that to the Radeon HD 5450, which uses a 40 nm design. AMD has set the core speed at 650 MHz. The DDR3 RAM runs at a speed of 800 MHz on this particular model. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5450		19 Watts
GeForce GTX 950M		55 Watts
	Difference: 36 Watts (189%)

Memory Bandwidth

The GeForce GTX 950M should in theory be a lot faster than the Radeon HD 5450 in general. (explain)

GeForce GTX 950M		32000 MB/sec
Radeon HD 5450		12800 MB/sec
	Difference: 19200 (150%)

Texel Rate

The GeForce GTX 950M will be quite a bit (more or less 603%) faster with regards to AF than the Radeon HD 5450. (explain)

GeForce GTX 950M		36560 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 31360 (603%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 950M is a better choice, by far. (explain)

GeForce GTX 950M		14624 Mpixels/sec
Radeon HD 5450		2600 Mpixels/sec
	Difference: 12024 (462%)

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 largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units of the card 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
