![]() The reality is that vendors in the mobile device industry tend to advertise what ends up being a boost or turbo clock rather than the nominal or steady state clock, something that needs to and hopefully will change once we’re out of the current mobile MHz race. One thing to keep in mind is that setting these cutoffs isn’t Qualcomm’s responsibility, rather it’s one of many knobs that OEMs have access to when building the software for a device, in this case Google with its Nexus 5. ![]() Thankfully the Nexus 5 doesn’t lock down its thermal configuration file, something I’ve seen other OEMs do. There’s obviously a balance between skin temp of the device (and in many cases the safe limits for regulatory compliance), accelerated aging of silicon from high temps, and of course throttling causing short-term performance erosion during certain use cases like playing games. The reality is that no mobile device right now is exempt from the realities of thermal throttling or the thermal constraints of a small mobile devices, even tablets. I Can't Believe I Still Have to Update This Table Thankfully Google continues to not do an app detect and performance mode switch for benchmarks or a small whitelist of apps. I also mentioned on the podcast that it’s likely that the fact Nexus doesn’t switch into using a performance mode governor upon detecting certain benchmarks also contributed to the delta. With the Nexus 4 the same was the case, although as we discovered thermal throttling prevented the Nexus 4 from looking as good as its other S4 Pro devices in benchmarks. On paper, the Nexus 5 should be the fastest in the Android landscape, since in terms of silicon it has the bleeding edge of what’s available right now. There’s also 2 GB of LPDDR3 at 1600 MHz data rate on a 2x32 bit interface for the whole system. Last year I was surprised to see Nexus 4 get APQ8064 at its price point, this year I guess I’m also surprised that Nexus 5 is able to ship the best current silicon from Qualcomm at its own price point. Technically what’s in Nexus 5 and other current other 8974 devices is 8974-AA. This is the higher 2.26 GHz (rounded up to 2.3 in most literature) clock, but don’t confuse it with the 8974-AB or -AC variants that it’s still a bit early for. We’ve seen Qualcomm’s latest silicon in a number of smartphones already, and it consists of four Krait 400 CPUs at up to 2.3 GHz, Adreno 330 graphics at up to 450 MHz, and integrated Category 4 LTE multimode modem, all built on TSMC’s 28nm HPM high-k process.
