Comparison of ARM processors

This is a comparison of ARM instruction set architecture application processor cores designed by ARM Holdings (ARM Cortex-A) and 3rd parties. It does not include ARM Cortex-R, ARM Cortex-M, or legacy ARM cores.

ARMv7-A

[edit]

This is a table comparing 32-bit central processing units that implement the ARMv7-A (A means Application[1]) instruction set architecture and mandatory or optional extensions of it, the last AArch32.

ARMv8-A

[edit]

This is a table of 64/32-bit central processing units that implement the ARMv8-A instruction set architecture and mandatory or optional extensions of it. Most chips support the 32-bit ARMv7-A for legacy applications. All chips of this type have a floating-point unit (FPU) that is better than the one in older ARMv7-A and NEON (SIMD) chips. Some of these chips have coprocessors also include cores from the older 32-bit architecture (ARMv7). Some of the chips are SoCs and can combine both ARM Cortex-A53 and ARM Cortex-A57, such as the Samsung Exynos 7 Octa.

  80. ^ a b c d Cutress, Ian (20 August 2017). "Analyzing Falkor's Microarchitecture". Anandtech. Retrieved 21 August 2017. The CPU cores, code named Falkor, will be ARMv8.0 compliant although with ARMv8.1 features, allowing software to potentially seamlessly transition from other ARM environments (or need a recompile). The Centriq 2400 family is set to be AArch64 only, without support for AArch32: Qualcomm states that this saves some power and die area, but that they primarily chose this route because the ecosystems they are targeting have already migrated to 64-bit. Qualcomm's Chris Bergen, Senior Director of Product Management for the Centriq 2400, stated that the majority of new and upcoming companies have started off with 64-bit as their base in the data center, and not even considering 32-bit, which is a reason for the AArch64-only choice here. [..] Micro-op cache / L0 I-cache with Way prediction [..] The L1 I-cache is 64KB, which is similar to other ARM architecture core designs, and also uses 64-byte lines but with an 8-way associativity. To software, as the L0 is transparent, the L1 I-cache will show as an 88KB cache.
