CPU DasherX is a sophisticated app that contains 140,000 lines of assembly code and over 30,000 Objective-C code to provide nice user experience, accurate CPU frequency and the best CPU performance, without any memory leak or crash. It contains no 3rd party libraries, no ads, no file-writing operations. It does not connect to the network. It provides pure and green functionalities so that it is safe and energy efficient.
It is a smart app that shows a lot of information in 64-bit mode for Apple A7 or later processors. It lists the device info, CPU info, almost all the 64-bit ARM instruction set(including general-purpose instructions and SIMD & VFP instructions) and the performance of several common algorithms, such as matrix multiplication, sum of an array, color-to-gray image processing algorithm and image convolution algorithm.
CPU DasherX evaluate the execution performance not only via CPU, but also via GPU with the most advanced Metal API. Each algorithm optimization is sophisticated and elaborate. They will demonstrate how well your current device can perform and you can use specific strategy on different devices when you're making an amazing app.
1. Optimized the info about the number of CPU cores.
2. Added iPad 6 info.
3. Improve GFLOPS and HFLOPS profile algorithm to better match Apple A11 chips.
Ratings and Reviews
Update seems to have introduced incorrect language for a lot of text in the app. All the tab buttons are in Chinese and previously were English.
Even the release notes in the AppStore for this app is partially Chinese.
Evidence I needed for battery replacement
This app showed 839Mhz frequency on my iPhone 6, out of max 1400. Despite the tech at the Apple Store telling me I didn’t need to replace the battery, I had it done anyway (taking advantage of the $29 price). Now I show 1400 again and no longer have the sluggish performance. Would recommend to anyone wondering if their CPU has been throttled.
Developer Response ,
Thanks for your review. I'm glad CPU DasherX is useful to you.😄
This app has been bought by Apple!
I have an over-two-year-old iPhone 6 Plus, and its Current Frequency is the same with Max Frequency!
Both of them are 1400 MHz! And always!
And I could just feel it’s much slower than that when I bought at the beginning!
Can you imagine that?!
In addition, I just purchased a new iPhone 8 Plus several days ago, whose Current Frequency is 2064 MHz and the Max Frequency is 2390 MHz.
Even though it’s a newly bought mobile, the current Frequency is smaller than the max, how could such an over-two-year-old one’s Current Frequency be the same with the max?! And always?!
And you gave the reason of new version to add the max Frequency to be your daughter’s birthday...
I don’t wanna curse anyone.
But you know, if you connect immoral thing with somebody, that person will be, sometimes, unlucky...

This means your 2-year-old iPhone 6 Plus is working well. It is not affected in this battery gate. iPhone X uses the modernest Apple A11 Bionic chip. It has 4 high-efficient cores that run at about 1.8GHz and 2 high-performance cores that run at about 2.38GHz.
Open CPU DasherX, select "Performance", and then select "Memory Bandwidth", you will see in extreme running environment, iPhone X will use the high-performance cores and that will be at the max frequency.
