AnandTech Finds iPhone 11 Pro Has Higher Performance Than iPhone XS

Written by Hassan Abbas

Today AnandTech published its in-depth review of the iPhone 11 and iPhone 11 Pro, including a detailed overview of the graphics and processor performance gains of Apple’s latest A13 Bionic chip.

Starting with CPU performance, AnandTech found the A13 chip is around 20 percent faster than the A12 chip. However, to fully achieve that improvement, the site claims Apple had to increase the consumption of the CPU cores:

“In virtually all of the SPECint2006 tests, Apple has gone and increased the peak power draw of the A13 SoC. In many cases, we’re almost 1W above the A12. Here at peak performance, it seems the power increase was greater than the performance increase. That’s why almost all workloads the A13 ends up as less efficient than the A12.”

A13 More Power-Efficient:

In terms of efficiency at the A13 chip’s AnandTech believes the higher power draw will likely result in both the chip. As a result, the iPhone is more sensitive to temperatures and prone to throttling.

Apple says the as compared to A12 chip A13 chip is up to 30 percent more power-efficient.

AnandTech emphasized Apple’s lead in the mobile chip space in term of overall performance. A13 posts almost double the performance of the next best non-Apple chip. The site also found the A13 “essentially matched” the “best that AMD and Intel have to offer” for desktop CPUs.

GPU performance:

AnandTech was even more impressed with GPU performance. Noting that while peak performance has improved by 20 percent iPhone 11 Pro had 50 to 60 percent higher performance scores than the iPhone XS.


AnandTech is widely known for its coverage of components like GPUs and CPUs, so its iPhone reviews are highly regarded. AnandTech founder Anand Shimpi joined Apple’s chipmaking team in 2014 and recently spoke about the A13 chip in an interview alongside Apple’s marketing chief Phil Schiller.
