GeForce GTX 1630 vs GeForce GTX 870M

Intro

Compare those specs to the GeForce GTX 870M, which uses a 28 nm design. nVidia has clocked the core frequency at 941 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this particular card. It features 1344 SPUs as well as 112 Texture Address Units and 24 Rasterization Operator Units.

GeForce GTX 1630		55680 Mtexels/sec
	Difference: 49712 (89%)

Pixel Rate

The GeForce GTX 1630 is much (approximately 23%) faster with regards to AA than the GeForce GTX 870M, and should be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 1630		27840 Mpixels/sec
GeForce GTX 870M		22584 Mpixels/sec
	Difference: 5256 (23%)

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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out 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 rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
