Compare any two graphics cards:
GeForce GTX 1630 vs Radeon HD 4870 2GB
IntroThe GeForce GTX 1630 features a GPU core speed of 1740 MHz, and the 4096 MB of GDDR6 memory is set to run at 1500 MHz through a 64-bit bus. It also features 512 SPUs, 32 TAUs, and 16 Raster Operation Units.Compare that to the Radeon HD 4870 2GB, which has GPU clock speed of 750 MHz, and 2048 MB of GDDR5 RAM running at 900 MHz through a 256-bit bus. It also features 800(160x5) SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4870 2GB should theoretically be just a bit faster than the GeForce GTX 1630 in general. (explain)
Texel RateThe GeForce GTX 1630 will be quite a bit (approximately 86%) better at texture filtering than the Radeon HD 4870 2GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 1630 is the winner, by a large margin. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
