Apple A12 chip in 2018 iPhones may sport 40% faster GPU, 10% faster CPU 4GB of RAM
French blog Consomac.fr (Google Translate) this morning dug up some claimed single and multi-core benchmarks from the Geekbench database showing speed gains and other improvements for the upcoming Apple A12 system-on-a-chip, destined to power 2018’s upcoming iPhone and iPad models.
Keep in mind that that it’s relatively easy to create bogus Geekbench scores.
Because the Geekbench app has yet to be updated with support for the unreleased Apple A12 chip, there are some inaccuracies in the listed characteristics, like clock speed or the number of cores. The new chip is expected to have four processing cores (two high-speed CPU cores and four low-power ones) like its predecessor, as well as a base frequency of 2.49GHz.
Here’s a comparison of the Geekbench scores against the A11 Bionic:
- Single-core: 4,673(Apple A12) 4,200 (Apple A11 Bionic)
- Multi-core: 10,912 (Apple A12) vs. 10,100 (Apple A11 Bionic)
- Metal score: 21,691 (Apple A12) vs. 15,234 (Apple A11 Bionic)
According to Valley Beat, there are some marked improvements in memory and crypto test scores and there are big jumps in face detection and speech recognition tests, suggesting faster Face ID and Siri.
The scores suggest modest speed gains of up to ten percent for the new chip although it should be noted that no one should read too much into these scores. Synthetic benchmarks like Geekbench simply measure the speed of the processor and the GPU under maximum load.
It does not take into account a myriad of factors that affect our sense of speed, like application opening times, boot times, the smoothness of the animations and the user interface, the speed of other crucial components such as flash storage, and what not.
The Geekbench page lists the tested chip as an ARM-based device featuring:
- “iPhone 11,2” device code
- D321AP motherboard
- 4GB of RAM
- 128KB L1 instruction cache
- 128KB data cache
By comparison, the current A11 Bionic chip inside iPhone X and iPhone 8 Plus models features three gigabytes of RAM (2GB of RAM in the normal-sized iPhone 8 model), as well as four times smaller L1 instruction and data caches at 32KB each.
In other words, the new iPhones will likely have four gigabytes of RAM for smoother, better multitasking and significant speed gains stemming from an improved process technology (A12 will likely be fabbed one TSMC’s cutting-edge seven-nanometer node), engineering optimizations and the larger caches speeding up executable instruction and data fetch.
