Compare any two graphics cards:
GeForce GTX 1050 Ti vs Radeon HD 4870 1GB
IntroThe GeForce GTX 1050 Ti has a clock speed of 1290 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 128-bit memory bus, and makes use of a 14 nm design. It features 768 SPUs, 48 TAUs, and 32 ROPs.
Compare those specs to the Radeon HD 4870 1GB, which has a clock speed of 750 MHz and a GDDR5 memory speed of 900 MHz. It also makes use of a 256-bit memory bus, and makes use of a 55 nm design. It is made up of 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the Radeon HD 4870 1GB should theoretically be a little bit better than the GeForce GTX 1050 Ti overall. (explain)
Texel RateThe GeForce GTX 1050 Ti will be a lot (approximately 106%) better at texture filtering than the Radeon HD 4870 1GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 1050 Ti is a better choice, and very much so. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number 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 many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
