chipmonk, that may be true, but I have to wonder on anything that this chip will be going into, whether UltraHD matters or are you thinking through an external HDMI port? The small displays of what it would go into including tablets would not be able to show all the resolution of UltraHD.
iniewski ... dual or quad would all come down to algorithm and software. For somethings, not much, for others, i.e some image processing where high parallelism is possible, then a lot.
eewiz, already the Qualcomm parts seem to be as fast at lower power than Samsung Exynos, so your comments does seem pretty valid.
running the SoC at 2.3 GHz is well and good but what about the bandwidth between the SoC and DRAM. Even w/ LP DDR 3 at 800 MHz that could be a choke point for flicker free Ultra HD video on the large display
I have always found it hard to get real details on the Qualcomm devices, but the Snapdragon product line looks to be a great performer. I look forward to the roll-out of the tablets powered by the quad processors running at over 2 Ghz. With this much power and memory options I can't help but wonder what the next generation of handhelds will be like.
"Qualcomm has not provided any detail of what has changed between Krait, which powers the S4 Pro, and Krait 300 and Krait 400. "
I guess the S4 Pro Krait was modded A9 and the latest Krait is modded A15.
IMO as ARM comes up more optimal CPUs the improvements from 3rd party architectural modifications will wither away.
