GeForce GTX 1050 Ti vs Radeon HD 5770

Intro

Compare those specs to the Radeon HD 5770, which uses a 40 nm design. AMD has set the core speed at 850 MHz. The GDDR5 memory works at a frequency of 1200 MHz on this particular card. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

GeForce GTX 1050 Ti		75 Watts
Radeon HD 5770		108 Watts
	Difference: 33 Watts (44%)

Memory Bandwidth

In theory, the GeForce GTX 1050 Ti is 49% quicker than the Radeon HD 5770 overall, because of its higher data rate. (explain)

GeForce GTX 1050 Ti		114688 MB/sec
Radeon HD 5770		76800 MB/sec
	Difference: 37888 (49%)

Texel Rate

The GeForce GTX 1050 Ti should be quite a bit (approximately 82%) more effective at AF than the Radeon HD 5770. (explain)

GeForce GTX 1050 Ti		61920 Mtexels/sec
Radeon HD 5770		34000 Mtexels/sec
	Difference: 27920 (82%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 1050 Ti is the winner, by a large margin. (explain)

GeForce GTX 1050 Ti		41280 Mpixels/sec
Radeon HD 5770		13600 Mpixels/sec
	Difference: 27680 (204%)

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 largest amount of information (counted in MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 processed in one second. This number is calculated by multiplying the total number of texture units by the core clock 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. 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 - the lower the bandwidth is, the lower the ability to get to the max fill rate.
