GeForce GTX 950M vs Radeon HD 5830

Intro

The GeForce GTX 950M has core speeds of 914 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Compare that to the Radeon HD 5830, which features GPU core speed of 800 MHz, and 1024 MB of GDDR5 RAM set to run at 1000 MHz through a 256-bit bus. It also is comprised of 1120(224x5) Stream Processors, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950M 55 Watts
Radeon HD 5830 175 Watts
Difference: 120 Watts (218%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5830 should be 300% faster than the GeForce GTX 950M in general, due to its greater bandwidth. (explain)

Radeon HD 5830 128000 MB/sec
GeForce GTX 950M 32000 MB/sec
Difference: 96000 (300%)

Texel Rate

The Radeon HD 5830 will be quite a bit (approximately 23%) better at AF than the GeForce GTX 950M. (explain)

Radeon HD 5830 44800 Mtexels/sec
GeForce GTX 950M 36560 Mtexels/sec
Difference: 8240 (23%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 950M is the winner, though only just barely. (explain)

GeForce GTX 950M 14624 Mpixels/sec
Radeon HD 5830 12800 Mpixels/sec
Difference: 1824 (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.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock 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 rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
