GeForce GTX 1050 vs Radeon HD 4870 2GB

Intro

Compare that to the Radeon HD 4870 2GB, which has a core clock speed of 750 MHz and a GDDR5 memory speed of 900 MHz. It also uses a 256-bit bus, and uses a 55 nm design. It is made up of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Texel Rate

The GeForce GTX 1050 should be quite a bit (more or less 81%) better at anisotropic filtering than the Radeon HD 4870 2GB. (explain)

GeForce GTX 1050		54160 Mtexels/sec
Radeon HD 4870 2GB		30000 Mtexels/sec
	Difference: 24160 (81%)

Pixel Rate

The GeForce GTX 1050 should be quite a bit (approximately 261%) more effective at AA than the Radeon HD 4870 2GB, and also able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 1050		43328 Mpixels/sec
Radeon HD 4870 2GB		12000 Mpixels/sec
	Difference: 31328 (261%)

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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, the result should 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few 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.
