Topaz Labs Gigapixel AI Software v5.7.3

This review is of Topaz Labs Gigapixel AI version 5.7.3 using the GPU as the AI processor.

The Topaz Labs Gigapixel AI software promises to increase resolution not just simply enlarging pixels. Examples include:

Add image detail that looks completely natural
Enhance the texture of feathers
Improve skin texture and sharpness
Higher-resolution landscapes
More detailed cityscapes
Crystal-clear upscaling with no blocky artifacts
Fix extreme pixellation in low-resolution images

Here is an example from the Topaz Labs website. After scouring the Internet, the source of the below image was found in full resolution so it can be compared.

Let's run the top image through Gigapixel AI v5.7.3 to see if similar results can be had.

None of the above images look as good as what is promised by the Topaz Labs website. Here is what the website promises again. Without pixel-peeping, The greatest improvement appears to be had by using the "very compressed" AI model.

There appears to be no improvement. Maybe it is not fair to use their examples off the website even though this seems perfectly reasonable. Let's use the original source to see if we can acheive the results that the Topaz Labs website shows.

Here, the original source is compressed with high-compression.

Here, the original source is compressed with medium-compression.

Here, the original source is compressed with low-compression so as to retain as much detail, like the bricks, as possible.

Conclusion

There does appear to be some minor benefit but this software is no where near as effective as the Topaz Labs website makes it look. This software is NOT recommended. Topaz Labs have better products than this one.

If there appears to be flaws in this testing methodology then please inform.
