    It does look underpowered though its very early drivers at the moment. Seems like firestrike gives about 17000 and OC getting it to 20000. In other thread GE75 with its 2080 non-max getting 28000 OC and about 25000 standard.

    Just wondering, are RTX 2080 for laptop using the lowest quality binned GPU? i've seen at least two clevo reviews showing minimal OC before crashing, both of which under 100MHz, more like 70MHz to be exact. how can this GPU OC so poorly? i can easily get 150MHz or more from GTX 1080 alienware R4 without crashing. What's going on here? Low quality binned GPU or power delivery circuit delivering insufficient power? let's hope this is just clevo GPUs.

    Why immediately you're linking this to low- quality binning ?

    It's most certainly tied to a lower voltage offset for the laptop GPUs, giving only a small room for OC. We'd need more tests with different voltage etc to know for sure.

    My Oc'd 1080 can reach 225 watts on it's own. That's due the OC bios removing the power limit. Frank azor bragged about the 17 R4 being able to handle 180 watts, so AW had to come up with a unlocked vbios. But the the problems started. Containing 180 watts is much harder than 150, especially with GPU boost 3.0 auto overclocking your GPU when the thermals are good.

    That spawned alot of people which already had problems with core imbalance, having 1080's drop utilization due overheating VRM's.

    Those are in part cause of the shared heatsink bleeding the best from GPU to CPU

    Or just power limited/ voltage limited to stop GPU boost 4.0 Ocing the card because maybe it's still an engineering sample. Of the chip would OC so bad, it wouldn't become a 2080 more a 2070 so it has a higher OC ceiling.

    Until it's not in the hands of the consumer, there are so many more variables apart from a bad binned chip that could be the culprit. Not trying to talk bad performance good, but where are still premature with our judgements when the real deal hasn't been out yet (consumer machine not a Chinese engineering sample with some iffy iffy performance just like with the 17 R5 release)

    I don't see you catching this clevo any time soon....

    And it's still severely limited!

    IF you can READ, i asked if this is low quality GPU bin OR power delivery circuit issue. this is open for discussion, not directly pointing at one specific cause. and unfortunately your theory is not correct too. prema got his GPU to OC way higher meaning the power delivery is not an issue but more of a low quality GPU bin

    Maybe Prema got lucky with a good GPU bin. The rest of the clevos sure didnt make it that far.

    Actually, that's a really good point - the possibility the mobile RTX GPU's are lower binned desktop components - as that might be the whole reason why the laptop RTX GPU's are clocked so low and so power limited.

    It did seem odd that the RTX laptop GPU's are being so under driven, as they don't even get close to the 10 series performance in their underclocked underpowered specification for laptop's.

    It might be that Nvidia needed a place for a large number of RTX GPU dies that wouldn't perform up to desktop specifications and by vastly lowering the clocks and power targets for mobile those RTX dies could be put to use.

    Good call, thanks for mentioning it. :)

    great minds think alike. i'm leaning towards this theory as well. otherwise why the nearly one month wait before lifting NDA on laptop rtx gpu? most likely to have enough time to collect poorly binned lowest quality GPU and throw it at the poor laptop buyers and charge them 2x as much
