https://www.macrumors.com/2020/08/17/apple-terminate-epic-developer-accounts-august-28/ Assuming Macrumours has an accurate quote of Apple's letter to Epic, there doesn't seem to be anything there about banning third-party games from using Unreal Engine. Banning Epic's developer account makes...

Given Epic's #FreeFortnite PR campaign, I wonder if it's enough that Apple just hunkers down and stays confident in their legal team or if they'll have to respond with their own counter-PR campaign to try to win/win-back hearts and minds? In any case, given the rapid timing of adding the direct...

http://www.realworldtech.com/apple-custom-gpu/ David Kanter has compared the optimization information provided by PowerVR and Apple and found they are quite different. He concludes that while Apple is still using PowerVR IP for the fixed function hardware, Apple has been using their own custom...

http://arstechnica.com/apple/2016/03/a-day-with-the-9-7-inch-ipad-pro-and-its-accessories/ Geekbench and GFXBench results are up. Overall the 9.7" iPad Pro has 95% of the single core CPU, 96% of the multi core CPU, 73% of the offscreen T-Rex HD, and 64% of the offscreen Manhattan HD performance...

https://twitter.com/jfpoole/status/647653497350037504 As an informative illustration on how benchmarks like Geekbench can be compiler dependent, they've found performance improves by 8% just by using a 2 year newer compiler. Things will be in flux even more going forward now that Bitcode is...

Onscreen results are capped at 60 fps so the GPU isn't being fully utilized in either cold or hot scenarios for those scores. EDIT: Turbotab beat me to it.

http://www.futuremark.com/pressreleases/understanding-3dmark-results-from-the-apple-iphone-5s-and-ipad-air Futuremark claimed Cylcone was held back when doing out of order memory accesses. Maybe Twister fixes this? Otherwise the GPU speedup would have to be massive to generate a high enough...

http://mashable.com/2015/09/22/apple-iphone-6s-plus-review/?utm_cid=mash-com-Tw-main-link#Vmyb1kCkGkkG Mashable has iPhone 6s Plus Geekbench results from it's 1.8GHz dual core A9: Single-core: 2521 Multi-core: 4380 Slightly higher than those twitter iPhone 6s results, but since the CPU clock...

I'm not sure what iOS developers are seeing in the average game when comparing a Metal code-path vs OES code-path, but didn't John Carmack used to say that bare metal access to console GPUs results in 2x more effective performance than if the same GPU ran high-level desktop APIs? Acknowledging...

https://www.ifixit.com/Teardown/iPad+Mini+4+Teardown/48891 So the iPad Mini 4's 2 GB RAM continues to be packaged together with the CPU like other A8 and not soldered separately on the motherboard like the 2 GB of the iPad Air 2. iFixit links to Hynix 1866 MHz LPDDR3 memory, but the "-NT"...

http://arstechnica.com/apple/2015/09/ipad-mini-4-performance-preview-a-1-5ghz-apple-a8-with-2gb-of-ram/ So in addition to the bump to 2 GB of RAM, the A8 in the iPad Mini 4 has also been up-clocked to 1.5 GHz. This is the same as the A8X in the iPad Air 2, missing a core of course. EDIT: Not...

https://www.apple.com/iphone-6s/3d-touch/ They are part of the new 3D Touch functions. For instance if you medium-press "Peek" on a link in an email in Mail, a mini-Safari overlay will open so you can preview that website. If you start pressing harder or you did a hard press to begin with, you...

http://www.macrumors.com/2015/09/13/xcode-iphone-6s-2gb-ram-ipad-pro-4gb-ram/ Xcode seems to confirm 2GB RAM for the iPhone 6s and 6s Plus and 4 GB for the iPad Pro. Peek and Pop in the new iPhones wouldn't be very effective as a time saving shortcut to briefly interact with another function or...

I guess you're right. I didn't know that LPDDR3 was now natively 64-bit rather than 2x32-bit.

The A7 was 2 x 32-bit LPDDR3, the A8 was 2 x 32-bit LPDDR3, and the A8X was 4 x 32-bit LPDDR3. Apple hasn't used a single channel memory controller since the A4. The Apple Watch uses a customized Cortex A7 core running armv7k. Apple could build a customized A53 core that can serve on its own in...
