If it was that easy Exynos wouldn’t already lag the A14 so badly. It should gain maybe 15% in a smaller process, but has a lot farther to go.

- ascar 5y agoI was curious about the actual performance difference and I don't know what the big name benchmarks are, but a quick Google search showed the centurion benchmark [1] which puts the A14 just 5% ahead of the newest Exynos and Snapdragons. That's not too big of a lead? Last years benchmark against the A13 showed a much bigger gap tho.

- GeekyBear 5y agoThe industry standard benchmark for completely different CPUs has been SPEC, going back to the days when every UNIX workstation vendor also had it's own custom CPU and instruction set. Exynos and Snapdragons aren't even close. https://www.anandtech.com/show/16252/mac-mini-apple-m1-tested/4 https://www.anandtech.com/show/16252/mac-mini-apple-m1-teste...
- jeswin 5y agoThe benchmark uses Snapdragon 865, not the newer generation. The Snapdragons also run at mobile phone power budgets.

- jeswin 5y agoThat's single threaded performance though. Snapdragons have more cores at the expense of single core performance.
- GeekyBear 5y agoThe Snapdragon 888 only has one X1 core.
- ascar 5y ago1x Kryo 680 (ARM Cortex X1-based) Prime core @ 2.84GHz, 1x 1MB L2 cache 3x Kryo 680 (ARM Cortex A78-based) Performance cores @ 2.4GHz, 3x 512KB L2 cache 4x Kryo 680 (ARM Cortex A55-based) Efficiency cores @ 1.8GHz, 4x 128KB L2 cache Vs 2 big 3.1 GHz and 4 small 1.8 GHz on the A14. Comparing single core performance is kinda cherry-picking a benchmark where the A14 is supposed to be ahead.
- GeekyBear 5y agoThe A55 is an in-order, 2 wide, low performance core from 2017 that was an embarrassing choice to put in a modern SOC a couple of years ago. Compare it to Apple's "little" Icestorm cores, which are at about the performance level of everyone else's big cores a couple of years ago. >The Icestorm design is actually a quite major leap for Apple as it sees the introduction of a third integer ALU pipeline, and a full second FP/SIMD pipeline, vastly increasing the execution capabilities of this core. At this point it would be wrong to call it a “small” core anymore as it now essentially matches the big core designs from Arm from a few years ago, being similar in complexity as an A75. https://www.anandtech.com/show/16192/the-iphone-12-review/2 https://www.anandtech.com/show/16192/the-iphone-12-review/2
