GeForce GTX 1050 Ti vs Radeon HD 4870 1GB

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1050 Ti		75 Watts
Radeon HD 4870 1GB		150 Watts
	Difference: 75 Watts (100%)

Memory Bandwidth

In theory, the Radeon HD 4870 1GB will be 0% quicker than the GeForce GTX 1050 Ti in general, due to its greater data rate. (explain)

Radeon HD 4870 1GB		115200 MB/sec
GeForce GTX 1050 Ti		114688 MB/sec
	Difference: 512 (0%)

Texel Rate

The GeForce GTX 1050 Ti should be a lot (more or less 106%) faster with regards to 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 quite a bit (approximately 244%) more effective at FSAA than the Radeon HD 4870 1GB, and also should be able to handle higher screen resolutions while still performing well. (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: Bandwidth is the max amount of information (measured in MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
