GeForce GTX 1050 Ti vs Radeon HD 4890 2GB

Intro

Compare all of that to the Radeon HD 4890 2GB, which features a GPU core clock speed of 1000 MHz, and 2048 MB of GDDR5 memory set to run at 975 MHz through a 256-bit bus. It also is made up of 800(160x5) Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Radeon HD 4890 2GB		40000 Mtexels/sec
	Difference: 21920 (55%)

Pixel Rate

The GeForce GTX 1050 Ti is quite a bit (about 158%) faster with regards to full screen anti-aliasing than the Radeon HD 4890 2GB, and will be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 1050 Ti		41280 Mpixels/sec
Radeon HD 4890 2GB		16000 Mpixels/sec
	Difference: 25280 (158%)

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 information (measured in MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
