Compare any two graphics cards:
GeForce GT 1030 vs Radeon HD 4830 512MB
IntroThe GeForce GT 1030 has a clock frequency of 1265 MHz and a GDDR5 memory frequency of 1502 MHz. It also makes use of a 64-bit memory bus, and makes use of a 16 nm design. It features 384 SPUs, 32 TAUs, and 16 ROPs.Compare all that to the Radeon HD 4830 512MB, which comes with core clock speeds of 575 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 RAM. It features 640(128x5) SPUs as well as 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 4830 512MB should theoretically be a bit better than the GeForce GT 1030 in general. (explain)
Texel RateThe GeForce GT 1030 should be quite a bit (about 120%) better at anisotropic filtering than the Radeon HD 4830 512MB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GT 1030 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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core 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 rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
