Today, ARM officially announced the cortex-X3, A715, A510 Refresh and other new ARMV9 products. For smart phones, tablets and laptops.
The Cortex-X3 and A715 are upgraded versions of the current Cortex-X2 and A710, with a 25% increase in peak performance and a 20% increase in hybrid performance and energy efficiency.
Both Cortex-X3 and A715 have abandoned the AARCH32 instruction set, meaning 32-bit applications are not supported at all and the architecture is 64-bit. Of course, ARM hasn't completely abandoned 32-bit architecture. In addition to improving performance, the A510 Refresh (V2) is compatible with the AARCH 32 instruction set, but only in certain options.
The compatibility and performance of 32-bit applications will be severely compromised. While not completely abandoning 32-bit applications, it is likely to be the last version supported.
In detail, the Cortex-X3 focuses on performance, with the decoder increasing from 5 to 6 instructions per cycle, out-of-order execution Windows from 288 to 320, and integer ALU units to 6. L2 cache increased from 512Kb to 1MB.
The result of the hardware improvements is a performance bump, 25% better than the previous Android flagship and 34% better than a laptop.
The A715 core focuses more on energy efficiency, saving 20% of the same performance compared to the A710, and improving performance by 5% for the same power consumption. Since the aARCH32 instruction set was abandoned, area efficiency soared, requiring only a quarter of the area of the A710.
The A510 V2 small core is still optimized for energy efficiency, with the same performance power consumption reduced by 5% and frequency increased by 5%, that is, from 1.8GHz to 1.9GHz.
In addition to 1+3+4, dCU-110 also supports 1+4+4, 2+2+4 and 8+4+0. The last one is designed for notebook computers.
The Cortex-X3, A715 and A510 V2 also feature advanced technology upgrades, as well as a convenient development platform and tool VFP for better simulation testing.
CPU architectures such as the Cortex-X3, A715 and A510 V2 will be available by the end of this year, with snapdragon 8 Gen 2, Exynos2300 and other chips expected to make use of the new architecture.
Notably, the newly released Cortex-X3, A715, and A510 V2, as well as Gpus such as Immortalis-G715, Mali-G715, and Mali-G615, collectively known as the TCS22 platform. Official information shows a 28% performance increase, a 16% reduction in power consumption and a 23% reduction in memory bandwidth requirements.
Unfortunately, the underlying architecture of this generation of CPU and GPU has not changed, but has been optimized and upgraded, and it is uncertain whether the heating problem can be completely solved.
Of course, ARM did give the CPU roadmap for the next two years, namely TCS23 and TCS24 platforms.
In TSC23, the supercore is the CXC23, next year's Cortex-X4, and in 2024 the CXC24, Cortex-X5 supercore.
The grand Core, code-named Hunter Hunter, is supposed to be the successor to the A715 core, with the Chaberton, model unknown, coming in 2024.
On the small core side, the current A510 was released in 2021, followed by a slightly revamped A510 V2 this year, which will be replaced by the Hayes architecture next year and the year after.
In addition, the MULTI-core CPU interconnection architecture is still Hayden, also known as THE DSU-110 series. The common combination of 1+3+4 core is common on mobile phones and tablets, and the maximum of 8+4+0 and 12 core architecture can be achieved on laptops.
Therefore, the most anticipated cortex-X4 ultra -, large - and small-core releases next year will be a complete update. The Cortex-X3, A715, and A510 V2 have not been significantly improved, and the limited performance improvements in next year's flagship will certainly affect users' intention to switch.
