Apple claimed that the A15 Bionic chip powering the iPhone 13 series is 50 percent faster than the rival chips, but a suite of exhaustive synthetic benchmark tests suggest that the latest A-series chip is actually up to 62 percent faster and leaves the competition far behind when it comes to graphics prowess as well. The A15 Bionic is based on TSMC’s N5P process. Which is just a slightly improved version of the 5nm process and that’s why supply chain sources frequently refer to its as the 5nm+ process.
Apple’s iPhone 13 Faster Reason
The fabrication node hasn’t shrunk when compared to the A14 Bionic inside the iPhone 12 series. And Apple hasn’t provided any side-by-side A15 vs A14 performance metrics either to quantify the generation-over-generation upgrades. Interestingly, Apple is offering its latest chip in two flavors. The version inside the vanilla iPhone 13 and its mini sibling has a 4-core GPU. While the model inside the iPhone 13 Pro models packs a more powerful 5-core GPU.
AnandTech performed its customary processor benchmark and stress test on the iPhone 13 series, and from the results, it appears that Apple may have undersold the power of its A15 Bionic chip. The company originally touted a performance gain of 50 percent over the closest rival chip. Which happens to be Qualcomm’s Snapdragon 888 SoC, and to some extent, Samsung’s Exynos 2100 chip. But during the benchmark tests, the A15 Bionic proved at least 62 percent faster than its rival chip fitted.
Faster CPU, And An Even Faster GPU Without Effienciency Woes
high performance gain usually means the energy efficiency has taken a hit, but Apple appears to have reversed the trend by boosting the energy efficiency of the A15 Bionic by approximately 17 percent compared to the A14 Bionic inside the iPhone 12 series. On a generation-over-generation level, the single-core frequency of the A15 Bionic’s performance cores is 8 percent higher. While the four efficiency cores record around 10.5 percent bump in speed. Talking about raw gains, the performance cores offer up to a 37 percent leap in output. While the efficiency cores are roughly 3.5x faster than the A-55 cores inside top-tier Qualcomm chips.
Another area where the A15 Bionic is far ahead of the competition is its 32MB of SLC cache. While the likes of Snapdragon 888 are limite to just 3MB. The 12MB of L2 cache is also significantly higher than rival chips, giving a huge performance advantage to the A15 Bionic. On the graphics side of things, the 5-GPU-core version of A15. Bionic offers up to a 30 percent performance boost. While the 4-GPU-core variant improves things by as much as 14 percent. Apple’s iPhone has made substantial improvements with the A15 Bionic, especially in the GPU department, and appears to have raced far ahead of what Qualcomm and Exynos chips bring to the table. It remains to be seen how Samsung can fill the graphics brawn gap with AMD’s help by bringing the RDNA-2. GPU architecture on its upcoming Exynos chip for flagships.
