GeForce GTX 950M vs Radeon HD 3650

Intro

The GeForce GTX 950M comes with a GPU clock speed of 914 MHz, and the 2048 MB of DDR3 RAM is set to run at 1000 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Compare those specifications to the Radeon HD 3650, which has core speeds of 725 MHz on the GPU, and 800 MHz on the 1024 MB of GDDR4 memory. It features 120(24x5) SPUs along with 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

Performance-wise, the GeForce GTX 950M should in theory be a lot superior to the Radeon HD 3650 overall. (explain)

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

Texel Rate

The GeForce GTX 950M will be a lot (approximately 530%) more effective at anisotropic filtering 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 (more or less 404%) faster with regards to FSAA than the Radeon HD 3650, and should be able to handle higher resolutions without slowing down too much. (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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the 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 most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
