GeForce GTX 1050 Ti vs Radeon HD 4850 2GB

Intro

Compare all that to the Radeon HD 4850 2GB, which makes use of a 55 nm design. AMD has set the core speed at 625 MHz. The GDDR4 memory is set to run at a frequency of 993 MHz on this particular model. It features 800(160x5) SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Radeon HD 4850 2GB		25000 Mtexels/sec
	Difference: 36920 (148%)

Pixel Rate

The GeForce GTX 1050 Ti should be much (more or less 313%) more effective at full screen anti-aliasing than the Radeon HD 4850 2GB, and should be capable of handling higher resolutions more effectively. (explain)

GeForce GTX 1050 Ti		41280 Mpixels/sec
Radeon HD 4850 2GB		10000 Mpixels/sec
	Difference: 31280 (313%)

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 data (measured in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen 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 texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
