GeForce GTX 1630		98304 MB/sec
	Difference: 16896 (17%)

Texel Rate

The GeForce GTX 1630 should be quite a bit (about 86%) faster with regards to anisotropic filtering than the Radeon HD 4870 2GB. (explain)

GeForce GTX 1630		55680 Mtexels/sec
Radeon HD 4870 2GB		30000 Mtexels/sec
	Difference: 25680 (86%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1630 is a better choice, by far. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon HD 4870 2GB		12000 Mpixels/sec
	Difference: 15840 (132%)

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 largest amount of data (in units of megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
