GeForce GTX 1050 Ti vs Radeon HD 4870 X2

Intro

Compare all that to the Radeon HD 4870 X2, 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.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1050 Ti		75 Watts
Radeon HD 4870 X2		350 Watts
	Difference: 275 Watts (367%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 4870 X2 is 101% quicker than the GeForce GTX 1050 Ti in general, because of its higher bandwidth. (explain)

Radeon HD 4870 X2		230400 MB/sec
GeForce GTX 1050 Ti		114688 MB/sec
	Difference: 115712 (101%)

Texel Rate

The GeForce GTX 1050 Ti will be a little bit (approximately 3%) better at anisotropic filtering than the Radeon HD 4870 X2. (explain)

GeForce GTX 1050 Ti		61920 Mtexels/sec
Radeon HD 4870 X2		60000 Mtexels/sec
	Difference: 1920 (3%)

Pixel Rate

The GeForce GTX 1050 Ti should be quite a bit (more or less 72%) more effective at anti-aliasing than the Radeon HD 4870 X2, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 1050 Ti		41280 Mpixels/sec
Radeon HD 4870 X2		24000 Mpixels/sec
	Difference: 17280 (72%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. 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 also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
