Compare any two graphics cards:
GeForce GTX 1050 3GB vs Radeon HD 3870 1GB
IntroThe GeForce GTX 1050 3GB makes use of a 14 nm design. nVidia has clocked the core frequency at 1392 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this card. It features 768 SPUs along with 48 Texture Address Units and 24 ROPs.
Compare that to the Radeon HD 3870 1GB, which uses a 55 nm design. AMD has set the core speed at 775 MHz. The GDDR4 RAM works at a speed of 1125 MHz on this card. It features 320(64x5) SPUs as well as 16 TAUs and 16 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 1050 3GB should in theory perform a bit faster than the Radeon HD 3870 1GB in general. (explain)
Texel RateThe GeForce GTX 1050 3GB is quite a bit (more or less 439%) faster with regards to texture filtering than the Radeon HD 3870 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 1050 3GB is superior to the Radeon HD 3870 1GB, 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.
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 largest amount of data (measured in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses 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 number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
