Compare any two graphics cards:
GeForce GTX 1630 vs Radeon HD 4870 512MB
IntroThe GeForce GTX 1630 has 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 those specifications to the Radeon HD 4870 512MB, which uses a 55 nm design. AMD has clocked the core speed at 750 MHz. The GDDR5 memory works at a frequency of 900 MHz on this particular model. It features 800(160x5) SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4870 512MB should in theory be just a bit faster than the GeForce GTX 1630 in general. (explain)
Texel RateThe GeForce GTX 1630 is much (about 86%) faster with regards to AF than the Radeon HD 4870 512MB. (explain)
Pixel RateThe GeForce GTX 1630 is quite a bit (more or less 132%) better at full screen anti-aliasing than the Radeon HD 4870 512MB, and also will be capable of handling higher screen resolutions better. (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 data (in units of megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 can be processed in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
