The new iOS 4.1 update for the iPhone and iPod touch offers security fixes and new features on different models. But does the new operating system change the speed of the phones? After running five benchmarks, we found no significant speed gains or losses on an iPhone 4, 3GS or 3G.
The benchmarks were first executed on the phones running the previous version of iOS, version 4.02. We then upgraded all the phones to 4.1. After running the benchmarks in 4.1, we found speeds on the various tests remained within about 10 percent of the iOS 4.02 results. Click on the charts below to see the scores.

Our benchmarks were split into three categories: processor and memory performance; application loading speed of a complex game; and Web browser performance.
Processor and Memory
BenchTest 1.4 ($0.99 in the iTunes store) tests memory allocation, floating point and integer calculation, 2D drawing performance using CoreGraphics, filesystem writes, and some JavaScript functions.
Geekbench 2 ($1.99 in the iTunes store) tests floating point and integer calculation and measures sustainable memory bandwidth and memory performance.
Application Load Time
"NFSU Launch" is the time for the device to launch "Need for Speed Undercover 1.2.0" ($4.99 in the iTunes store) to playable mode.
Web Browser Performance
SunSpider and V8 (version 5) are complex JavaScript benchmarks that test JavaScript runtime performance. The iPhone 3G could not run the entire V8 suite, so we picked two tests, "Richards" and "EarlyBoyer."
All tests were run with devices connected to a Wi-Fi network.
