Apple IPhone 6 Plus Review: Following The Curve: Performance

By 05:14 Sun, 15 Aug 2021 Comments


Performance

The iPhone 6 Plus, just like the iPhone 6, is running on the recent generation Apple A8 chipset. It is manufactured by a recent 20nm process, which means smaller parts, less heat and less power consumption.

Just like the past few years Apple didn't specify the A8 specifications, but thanks reverse engineering of the chip the details are no longer a secret. Apple A8 inside the iPhone 6 Plus packs a dual-core 64-bit Cyclone processor clocked at 1.4GHz. It is 100Mega Hertz (MHz) faster than the processor inside the A7 (iPhone 5s), but it requires less power to run. There are suggestions that L1 and L2 Central Processing Units (CPU) caches are larger and the L2 isn't shared as before, but this is yet to be confirmed.

The other more prominent upgrade in the Apple A8 is the recent generation GPU - the PowerVR GX6450 with four GPU cores. The A7 chip used a quad-core PowerVT GX6350, which was quite the performer, but Apple needed something even better for the higher resolution iPhone 6 and iPhone 6 Plus. The GX6450 within the Apple A8 also uses four GPU cores, but the newer generation should be enough to provide the necessary graphic boost.

So, there is no better way to illustrate the actual Apple A8 performance than with some synthetic benchmarks.

We start with the Geekbech 3 test to see how the overclocked Central Processing Units (CPU) and memory are doing. The iPhone 6 Plus did great, providing 20% performance boost over the iPhone 5s predecessor and on par with the current crop of Snapdragon 801 flagships. The octa-core Galaxy Alpha isn't that far ahead either.

The Baseimprint Operating System (OS) II gives an overall device score based on CPU, graphics, system performance, memory, web, among others. Surprisingly, the recent iPhone 6 duo climbs on top of our chart beating every device we've tested so far and on par with the upcoming Samsung Galaxy Note 4 and Note Edge phablets powered by the latest Snapdragon 805 chipset.

As we mentioned before, the Apple iPhone 6 Plus comes with a brand recent PowerVR GX6450 GPU. It uses four GPU cores for both the iPhone 6 and iPhone 6 Plus, but its clock is quite possibly higher on the Plus model becautilize it has an even better performance despite its higher resolution. First we ran the Baseimprint X graphic benchimprint and we were surprised to find the iPhone 6 and iPhone 6 Plus to be the best phones we've tested to date. This made us suspicious and we found out that Baseimprint X, as well as the GFX Benchmark, on the iPhone 6 Plus (and possibly the iPhone 6) utilize upscaled graphics for the on-classy screen tests due to the lack of proper support for the recent devices, hence the surprisingly fine score.

So the on-classy screen benchmarks are obsolete for now, but we can still check how the recent PowerVR GX6450 stacks up against the competition thanks to the off-classy screen 1080p torture tests.

The offclassy screen raw performance of the PowerVR GX6450 in the iPhone 6 Plus turned out great, topping our all-time charts. Apparently the PowerVR GX66450 GPU is a real beast, handling heavy graphics with ease. It's obvious that in terms of hardware the recent iPhone is not behind the curve but just on the contrary - it's ahead of it.

If the remarkable Central Processing Units (CPU) and GPU scores on the benchmarks didn't convince you enough the recent iPhone 6 Plus is a real powerhoutilize featuring flagship hardware and software, then here come the web browser tests. Both the JavaScript-centric Kraken and the compound BrowserMark 2.1 confirm the iPhone 6 is among the best performers on the market and the device newcomers have to beat.

These benchimprint results might come shocking for some, but they really aren't. The recent GPU is better in every way against the current crop of flagships, but we are yet to see what the Adreno 420 with the Snapdragon 805 and the Nvidia Kepler in the Tegra K1 will bring on the market. The upgraded dual-core Cyclone processor seems to be handling things way better than expected providing similar performance as a quad-core Krait 400 CPU.

Judging by the raw performance in the benchmarks and the snappier than ever user experience with the iOS 8 and its apps, the recent iPhone 6 Plus is a flagship device in every way - beating everything the competition has to offer to date.
