I assume you're referring to lens which was a common design/model among Avago office based sensors. Sensor model A5050 for example also found it's way into knock off products like the first picture you linked.
In terms of frames A5050 runs at a maximum of 4500. Other office architectures per brand identity are also fairly close ranging anywhere around 4k. Contrary to A5050, Avago released a gaming oriented model sold under A3050 branding in 2011. This model offers a much higher 6666 maximum frame integer. There are also a few noticeable hardware differences when comparing the two.
Being a custom design with gaming in mind, one would doubt a downgrade, but like mentioned, there is no documentation. The CPI stepping setup is fairly close to that of previous 3050 and custom A3055. One thing that can't be ignored is obvious changes to tracking coding per model, though the original G100 can be proven to have 6666 FPS based on rating Korean and Chinese Logitech pages gave.
I would also like to clarify megapixel/s ratings as there's a big misconception. A sensor can have a small matrix and high framerate or a low framerate and large matrix and be rated with the same specs.
That means if willing, a sensor designer could pair a large matrix with relatively low frame rate and label that sensor with a higher MP/S rating compared to other common designs mentioned. I don't really like this rating model as there are two sides of the spectrum.
A3050 per documentation is quite close to the first release of ST MLT04. It's limited by a smaller array, but is bumped in frames.
19*19 @ 6666 vs 22*22 @ 6000 or 2.4mp/s vs 2.9 mp/s respectively. Frame rate is of course dynamic based on surface. One major difference is that the Avago model is heavily modified in terms of coding.
I don't know anything bout the inconsistency of tracking, but my impressions of G100s were rather well. Just don't like the idea that they're using weaker hardware in design I much like.
