GeForce GTX 1050 Ti vs Radeon HD 5770

Intro

Compare those specifications to the Radeon HD 5770, which uses a 40 nm design. AMD has set the core speed at 850 MHz. The GDDR5 RAM runs at a speed of 1200 MHz on this particular model. It features 800(160x5) SPUs as well as 40 TAUs and 16 ROPs.

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

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1050 Ti should be 49% faster than the Radeon HD 5770 overall, due to its greater 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 will be a lot (more or less 82%) faster with regards to texture filtering than the Radeon HD 5770. (explain)

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

Pixel Rate

The GeForce GTX 1050 Ti should be much (about 204%) faster with regards to AA than the Radeon HD 5770, and also will be capable of handling higher resolutions without losing too much performance. (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 maximum amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 are processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
