One lucky Apply customer has already received her rose gold iPhone 6s while other Apple fans who have pre-ordered the company's next-generation iPhoneshave to wait until later this week to receive their new iOS devices.

It's worth mentioning that although the worldwide launch of the iPhone 6s and 6s Plus won't be until this Friday, pre-orders have already been shipped to several mobile carriers across different launch locations.

Ideally, couriers should hold the shipment until the intended launch. However, a few lucky customers often receive their pre-orders ahead of time due to unforeseen logistical errors, such was the case with Adrienne Alpern.

Alpern is a visual designer from San Diego, California. She was surprised to learn that her pre-ordered rose gold iPhone 6s from AT&T had been delivered to her ahead of schedule, MacRumors reported.

After unboxing the device, Alpern then took to social media to share snapshots of her new iPhone 6s.

Interestingly enough, Alpern also subjected the device to a benchmark test to find out how its new A9 processor would fare with other flagship devices. Click here to view the benchmark screenshot.

The GeekBench results show the iPhone 6s tallying a score of 2,292 to 2,413 in the single-core test and 4,293 in the multi-core test. For comparison, the older iPhone 6 garners a single-core score of 1,609 while its multi-core score hovers around 2,879.

"If the leaked Geekbench scores are correct, a lot of the A9 performance increase comes from a big clock speed increase (1.8 GHz vs 1.4 GHz)," GeekBench Founder John Poole posted on his Twitter account.

Poole also stated that the GeekBench scores of the iPhone 6s and the entry-level 2015 MacBook were approximately the same.

WCCF Tech was then kind enough to compare the iPhone 6s benchmark results to that of Samsung's current-gen. flagship devices. Click here to view the comparison table.

Even though the Galaxy S6 Edge Plus, S6 Edge, Note 5 and Note 4 have higher multi-core test results than the iPhone 6s, all aforementioned Android devices have twice the RAM and four times the number of cores than the new iOS offering.

The amount of RAM and number of cores pale in comparison to the optimization of a software platform present on the iPhone 6s, WCCF Tech reported.

The superiority of the Apple's A9 processor was evident in the iPhone 6s' single-core test result. It garnered a whopping score of 2,292, almost double the scores of each of the aforementioned Samsung flagship devices.

The iPhone 6s and 6s Plus will launch in 11 countries on Friday, Sept. 25.
