Have The First A15 Benchmarks Leaked? Huge Performance Leap But Lots Of Throttling

The upcoming iPhone generation is more than likely to receive a new A15 chip, which would be both more powerful and energy-efficient than Apple's previous A14 SoC (system on a chip). Recently, alleged benchmarks for the A15 appear to have popped up. According to these benchmarks, there are considerable increases in performance in comparison to Apple's A14. However, the A15 is only able to maintain this level of performance over a relatively limited period of time, after which it begins to throttle its performance level in favor of energy efficiency and lowered heat production. For day-to-day usage, this is extremely practical. The average daily user is rarely ever going to need continuous extremely high-performance output – making the device's ability to push out temporary performance sprints when needed extremely useful.

A Huge Increase In Graphics Performance...
The alleged A15 SoC managed to achieve a value of 198 FPS (frames per second) in its first pass of the circulating Manhattan benchmarks for graphics performance. For comparison – in the same performance test the iPhone 12 only manages 120 FPS. The difference between the two chip versions is clear – at least as long as the recently "released" A15 benchmarks are legitimate.



...That's Barely Noticeable After Throttling
However, there's one tiny limitation to the A15's SoC – the graphics unit is only able to achieve the impressive aforementioned values during the first pass. Afterwards – likely to combat excessive heat development, the unit is throttled and the performance results suffer a decrease, although the new chip still achieves a value of 140-150 FPS (so, still about 20-30 FPS better than the iPhone 12).

Samsung's Upcoming SoC Rises To Meet The Competition
In addition to benchmarks from Apple's A15 chip, benchmarks for Samsung's upcoming high-end SoC (the Exynos 2200) have also been allegedly released. Equipped with an AMD RDNA GPU, the new Samsung chip manages 170.7 FPS in the same Manhattan benchmarks.

Manhattan 3.1 GPU Benchmark
The performance tests were all completed using the Manhattan 3.1 GPU Benchmark used to measure the performance of smartphone chips. A user of the South Korean forum Clien released the benchmarks, said to come from an A15 produced in July. However, since the authenticity of these benchmark values isn't entirely verifiable, the results may not necessarily be 100% indicative of the A15's true performance values. 100% reliable benchmarks won't be possible to produce until after the release of the iPhone 13.
