GeForce GTX 1050 Ti vs Radeon HD 4870 1GB

Intro

Compare that to the Radeon HD 4870 1GB, which comes with a GPU core clock speed of 750 MHz, and 1024 MB of GDDR5 memory set to run at 900 MHz through a 256-bit bus. It also is made up of 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

The GeForce GTX 1050 Ti is quite a bit (more or less 106%) more effective at texture filtering than the Radeon HD 4870 1GB. (explain)

GeForce GTX 1050 Ti		61920 Mtexels/sec
Radeon HD 4870 1GB		30000 Mtexels/sec
	Difference: 31920 (106%)

Pixel Rate

The GeForce GTX 1050 Ti should be a lot (approximately 244%) more effective at FSAA than the Radeon HD 4870 1GB, and will be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 1050 Ti		41280 Mpixels/sec
Radeon HD 4870 1GB		12000 Mpixels/sec
	Difference: 29280 (244%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units by the core clock 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs 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 rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
