m1 chip and a14 difference and comparison:
1. Appearance size
< p >
Due to the need to consider lower power consumption and battery life, the A14 is designed for lower performance than the M1, and the bare chip area is smaller than the M1, and the A14's bare chip size is approximately 37% smaller than the M1
2. Core number
GPU with the same architecture, a 4 core, an 8 core, IPC is twice the difference, if the frequency is different, the gap will be further widened
The CPU is similar, with a double big core and a four big core. But so far the number of micronucleus is consistent
3. Run the score test
The large core of M1 is the same as that of A14, both of which are Firestorm. SPEC06 can be estimated using the data of A14 before (the IPC relative attenuation of high frequency is not considered here).
< p >
Looking at integers and floating points together, M1 does claim to be about 50% better than A14 in terms of large cores
This is what the IPC gap looks like:
< p >
In fact, the small nuclear Icestorm of the A14 family has also been greatly improved, and the small nuclear IPC of the A13 alone has been improved by about 30%. On the GPU side, M1 is the same as A14, but the scale is much larger than A14, A14 is a quad-core GPU, M1's GPU has eight cores, but when A14 was released, it was also just advertised that GPU performance was 30% higher than A12, and M1's GPU performance was 40% stronger than A12Z at the same scale. Do not know whether it is to increase the frequency or other reasons, such as improving the memory bandwidth, and did not say what type of memory, if the 40% increase as a reference, Manhattan 3.1 frames may reach 315 frames, once again refresh the ARM side of the mobile GPU performance ceiling.
Step 4 Summarize
The overall difference is that the M1 has a larger CPU cache to speed up instruction and data access and reduce latency, but the system cache is smaller than the A14. The M1 also has more CPU and GPU cores, as well as a DDR high-speed memory interface (8 to 4). More dedicated modules are included, optimized for desktop applications with low energy saving requirements. Compared with A14, the nude size of M1 has increased by 37%, of course, M1 is better than A14 as a new product.
