    So no details yet on the 615? Was curious if there is more than just clocks that differs between the 2 clusters.
    Noticed that the dimensions (H and W) are very close to the rumored dimensions for the iphone 5.5 (so too bulky compared to other 5.5 inch devices) at 157.7 x 78.74.
    Somehow HTC got the first dibs on both the 410 and 615 , made me remember that Qualcomm was an investor in HTC , not sure if they still are and how much of it they might own.
    Anyway, eager to see how A53 does since it should rule the mid range and bellow for a while now.

    I don't think the 615 will impress, it is a lower mid-range product. A53 is about as fast as A9, so at best it will be around the same performance as "el-cheapo" octa cores like the one mediatek has. Worst case, all 8 cores would not be usable by a single multithreaded process or load balancing would not work well due to the difference in clock speeds.

    That's what I wonder, why 4 cores are lower clocked? Considering cores should be able to independently clock 8 identical cores would make more sense, especially considering it is a monolithic die, it is not like they will snap 4 high and 4 lower bin cores to make for an odd "big-little" or more like "little-tiny" config.

    That's not quite true ,yes the A53 should be slightly faster than the A9 and that also means that is plenty faster than A7. Plus the perf is not just the core. So this should be quite a big step vs A7 and does make it very interesting. After all most devices shipping now worldwide are A7 or A9 based.
    I wondered too about why bother ,if the only diff is in clocks between clusters and maybe it's about TDP or maybe the diff is more than clocks ,guess we'll find out soon.

    One cluster is optimized for low power, the other for high performance as the article states. I agree the difference in power and performance seems relatively small, but it's indeed faster than 8x A7 or 4x A9 in current mid-end. Reply

    Nice selection of colours.
    White, white, white, grey, grey, grey, grey, blue or orange.

    So the Desire comes in, like, fifty shades of grey? Coincidence... or sleazy upcoming marketing opportunity? HTC will probably sell just about anything for a little cash right now. Reply

    50 is far from 4... but... whatever. And they are TINTS of grey, not shades. Reply

    Another HTC phone, hope its as good as M8 which is a top rated phone in terms of consumer satisfaction. /craig from Reply

    It looks like a massive camera lens, but i dont see anyone mention it specifically. Reply

    Seems like dynamically changing clocks makes more sense than 4 more of the same cores at a lower clockspeed... But, well, I trust Qualcomm knows what it is doing. Reply

    Most any modern processor can dynamically change clock rates and voltage as needed to reduce power consumption or increase performance. But they can only operate within a given range for which they are tuned. Higher performance cores can clock higher and/or have better IPC, but are generally more power hungry. Lower voltage cores are much the opposite.

    Combing the two in an asymmetrical setup is strange and may seem at first like a poor use of die space but it can work out well in mobile devices - especially ones that are always on but yet spend a lot of time idling or running very light workloads. Running on the low power cores for most of the day makes a lot of sense, and you've got the heavier punch of the faster cores on demand.
