GeForce 830M vs GeForce GTX 550 Ti

Intro

The GeForce 830M makes use of a 28 nm design. nVidia has clocked the core speed at 1029 MHz. The DDR3 memory is set to run at a speed of 900 MHz on this model. It features 256 SPUs along with 16 TAUs and 8 Rasterization Operator Units.

Compare that to the GeForce GTX 550 Ti, which uses a 40 nm design. nVidia has set the core frequency at 900 MHz. The GDDR5 memory runs at a frequency of 1026 MHz on this specific card. It features 192 SPUs along with 32 Texture Address Units and 24 Rasterization Operator Units.

GeForce GTX 550 Ti 98496 MB/sec
GeForce 830M 14400 MB/sec
Difference: 84096 (584%)

Texel Rate

The GeForce GTX 550 Ti should be a lot (approximately 75%) faster with regards to texture filtering than the GeForce 830M. (explain)

GeForce GTX 550 Ti 28800 Mtexels/sec
GeForce 830M 16464 Mtexels/sec
Difference: 12336 (75%)

Pixel Rate

The GeForce GTX 550 Ti should be quite a bit (approximately 162%) faster with regards to FSAA than the GeForce 830M, and also should be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 550 Ti 21600 Mpixels/sec
GeForce 830M 8232 Mpixels/sec
Difference: 13368 (162%)

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 max amount of data (in units of MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
