Compare any two graphics cards:
GeForce GTX 1050 Ti vs Radeon HD 4870 1GB
IntroThe GeForce GTX 1050 Ti makes use of a 14 nm design. nVidia has clocked the core frequency at 1290 MHz. The GDDR5 memory is set to run at a speed of 1750 MHz on this specific model. It features 768 SPUs along with 48 Texture Address Units and 32 Rasterization Operator Units.
Compare those specs to the Radeon HD 4870 1GB, which comes with a core clock frequency of 750 MHz and a GDDR5 memory frequency of 900 MHz. It also makes use of a 256-bit memory bus, and makes use of a 55 nm design. It features 800(160x5) SPUs, 40 TAUs, and 16 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the Radeon HD 4870 1GB should in theory be a bit superior to the GeForce GTX 1050 Ti in general. (explain)
Texel RateThe GeForce GTX 1050 Ti should be a lot (approximately 106%) more effective at anisotropic filtering than the Radeon HD 4870 1GB. (explain)
Pixel RateThe GeForce GTX 1050 Ti is quite a bit (about 244%) more effective at full screen anti-aliasing than the Radeon HD 4870 1GB, and capable of handling higher 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.
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: Memory bandwidth is the max amount of data (measured in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
