Compare any two graphics cards:
GeForce GTX 1630 vs Radeon HD 4870 512MB
IntroThe GeForce GTX 1630 makes use of a 12 nm design. nVidia has clocked the core speed at 1740 MHz. The GDDR6 RAM is set to run at a frequency of 1500 MHz on this model. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.Compare those specifications to the Radeon HD 4870 512MB, which makes use of a 55 nm design. AMD has clocked the core frequency at 750 MHz. The GDDR5 RAM works at a frequency of 900 MHz on this specific card. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 4870 512MB should be 17% quicker than the GeForce GTX 1630 in general, because of its higher data rate. (explain)
Texel RateThe GeForce GTX 1630 should be a lot (about 86%) faster with regards to anisotropic filtering than the Radeon HD 4870 512MB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 1630 is a better choice, by far. (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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's bus 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 ANOTHER 2x. 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 number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
