![]() ![]() ![]() If Intel can get Bay Trail to do 2.4GHz on something like 1.0V, then the power should be fine. smartypnt4 - Wednesday, Septemlink Frequency and process matter in that they affect power consumption.What with Apple's next stuff, Broadwell, the first A57 designs, Airmont, and whatever Qualcomm puts out (haven't seen anything on that, which is odd for Qualcomm.) Next year will be really interesting, though. That's not a given since they had to use ~50% more transistors to get a performance doubling from the A6 to the A7, and building a 1.5B transistor chip is nontrivial since yields are inversely proportional to the number of transistors you're using. Next year's A8 or whatever probably will compete directly with Haswell in raw theoretical integer and FP throughput, if Apple manages to double performance again. Now, I will agree that this does prove that if Apple really wanted to, they could build something to compete with Haswell in terms of raw throughput. You can't just say "oh, I want these to switch faster, so let's up the voltage." There's more that goes in to the ability to scale voltage than just the process node you're on. That's assuming such a scaling could even be done, which is unlikely given that Apple built the thing to run at 1.3GHz max. If Apple wanted to double the frequency of the chip, they'd need something on the order of 4x the amount of power it already consumes (assuming a back-of-the-napkin quadratic relationship, which is approximately correct), putting it at ~6-8W or so at full load. smartypnt4 - Wednesday, Septemlink Why does the frequency matter? If the TDP of the chips are similar (Bay Trail was tested and verified by Anand as using 2.5W at the SoC level under load), who gives a flip about the frequency?.Standard 1080p30 recording is also available: ![]() Technically 1080p60 does require slightly more bandwidth than 720p120, but I’d hope that Apple targeted both in the design of H6 and simply chose to expose 720p120 as it’s an easier feature to market. I would like to see Apple expose a 1080p60 mode as well. Video preview in slo-mo mode also happens at 60 fps compared to 30 fps for the standard video record and still image capture modes.Ĭamera preview frame rate, toggling between slo-mo and normal modesĪdding high speed camera modes to smartphones is a great step in my opinion and a wonderful use of increases in ISP and SoC performance. The slo-mo mode is separate from the standard video recording mode, it’s the next stop on the dial in the new iOS 7 camera app. mov file is stored on NAND as a ~27Mbps 720p120 without any customizations, however when you share it the entire video is transcoded into a 30 fps format which preserves the slow motion effect. In the camera UI you can select what portions of the video you want to play back at 30 fps and what portions you want to leave at full speed. ![]() In the latter, video is captured at 120 fps but optionally played back at 30 fps in order to achieve a high speed camera/slow motion effect. The default video record mode is still 1080p at 30 fps, but there’s also a new 720p 120 fps “slo-mo” mode as well. Apple’s new H6 ISP brings with it a modernization of the video recording options for the iPhone 5s. ![]()
