Test: iPhone 8 and iPhone 7 performance after the Spectre and Meltdown patches

Smart Android And Trik-Commenting on Andorid indeed never endless, because smart devices this one is often updated every certain amount of time. So that the market can always be garapnya menerinya with pleasure. And it is not denied if this device has become the lifestyle of each society. To not wonder if the 6th business information and many are turning to mobail smartphone. With Android which thoroughly dominated the mobile industry, choosing the best Android smartphone is almost identical to choose the best smartphone, period. But while Android phones have few real opponents on other platforms, internal competition is intense.

From the sleek devices impress with the design premium, up to a full plant furniture features, to a very good device, and affordable mobile phone has a heavy weight, the Android ecosystem inhabited by a diverse range of attractive mobile phone Test: iPhone 8 and iPhone 7 performance after the Spectre and Meltdown patches Test: iPhone 8 and iPhone 7 performance after the Spectre and Meltdown patches,But "oversize" are subjective, and sometimes pieces of the specification and a list of features is not enough to get an idea of how good a phone. In this roundup, we look at the absolute best-the Android phone you can't go wrong with. The habits of young people or to accentuate trand blindly lifestyle, make this a medoroang this clever device industry vying to do modifications to the device, with a distinctly vitur vitur-tercanggihnya. So it can be received over the counter Test: iPhone 8 and iPhone 7 performance after the Spectre and Meltdown patches

Sectre and Meltdown shook the tech industry – they allow malicious code to peek at protected data. They do it by exploiting CPU features meant to speed up execution, so the solution is simple but unpleasant – devs have to circumvent those performance-enhancing features.

We were prompted by the huge performance hit to the iPhone 6 after the update to see if the newer models are similarly affected.

So we found an iPhone 8 Plus at the office that was still running iOS 11.1.2 – before either patch. We ran Geekbench and AnTuTu then installed iOS 11.2.2 and ran them again.

Long story short there’s little change. The processor performance suffers a minimal loss in performance, too small to notice. RAM speed seems unaffected (both Spectre and Meltdown exploit the CPU cache, so slower RAM access is one of the possible issues when patched).

We tried running AnTuTu on an iPhone 7, which was still running iOS 11.1.2. We didn't see any change in performance either. Actually, after the update the score is about 3% higher, but that's down to the variance in the benchmark test itself.

We couldn't find a pre-update iPhone 6s, so we're not sure when a vital CPU upgrade occurred to make the Spectre and Meltdown patches a non-issue. But the iPhone 7 is already two generations old (it launched in September 2016) and you can keep using it for a while longer.
