GeForce GTX 950M vs Radeon HD 3650

Intro

Compare all that to the Radeon HD 3650, which features GPU clock speed of 725 MHz, and 1024 MB of GDDR4 RAM set to run at 800 MHz through a 128-bit bus. It also is comprised of 120(24x5) Stream Processors, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950M		55 Watts
Radeon HD 3650		78 Watts
	Difference: 23 Watts (42%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 950M will be 25% quicker than the Radeon HD 3650 in general, due to its greater data rate. (explain)

GeForce GTX 950M		32000 MB/sec
Radeon HD 3650		25600 MB/sec
	Difference: 6400 (25%)

Texel Rate

The GeForce GTX 950M is quite a bit (approximately 530%) more effective at AF than the Radeon HD 3650. (explain)

GeForce GTX 950M		36560 Mtexels/sec
Radeon HD 3650		5800 Mtexels/sec
	Difference: 30760 (530%)

Pixel Rate

The GeForce GTX 950M should be quite a bit (about 404%) faster with regards to FSAA than the Radeon HD 3650, and also will be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 950M		14624 Mpixels/sec
Radeon HD 3650		2900 Mpixels/sec
	Difference: 11724 (404%)

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 (measured in MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
