Well kinda, over at CES Samsung had the new Odyssey gaming laptop on display. However somebody noticed something interesting on the spec list as a Radeon RX 570 is mentioned, which would be a mobile part.
AMD obviously has not confirmed or even announced an RX500 series mobile GPU, and for a big name like Samsung to put out that info on a spec list, is interesting alright.
What is also interesting is that the Odyssey gaming laptop can be fitted with either a GeForce GTX 1070 or this that Radeon RX 570, indicating they both are at roughly a similar performance level. One last fact, on that spec list you can see that the Radeon RX 570 would be either a 4 GB or GB (graphics memory) model.
If we'd speculate a little bit, this might simply be a re-branded OEM version of the Radeon RX 470 series, thus Polaris. Intersting none the less.
