ARM introduces the Cortex-X4, its most powerful CPU

ARM Since their introduction, little CPU architectures have often consisted of as many little cores as large ones, if not more. The advent of ARM’s new designs is now altering this.

announcement of the high-power Cortex-X4, intermediate Cortex-A720, and compact Cortex-A520 will help find a compromise between performance and efficiency. The DSU-120, which powers the DynamIQ Shared Unit technology that enables many CPU cores to cooperate, was also unveiled by ARM.

High-end chipsets now available come in 1+3+4 or 1+4+3 combinations. The DSU-120 supports processors with up to 14 cores, but smartphones are likely to only have 8 overall. Even so, 1+5+2 is probably going to become the new standard configuration.

Cortex-X4: optimized performance

Heavy single-threaded operations will be performed by the new Cortex-X4, which claims 15% better performance than the X3 on an equivalent power basis (which itself was 25% quicker than the X2). The X4 may provide a staggering 40% decrease in power utilization for equivalent performance. But, the X4 is made for speed—it is the fastest CPU core ARM has ever created and is expected to reach clock rates of 3.4GHz.

Even more, than the A700 cores before it, the Cortex-A720 has been designed for efficiency. Its efficiency is 20% higher than that of the A715, which was 20% more effective than the A710. They will efficiently do a lot of the heavy lifting for multi-threaded tasks thanks to their five A720 cores.

built the most powerful cluster ever

The Cortex-A520 is still an in-order core, to summarize. In order to use the least amount of silicon area feasible, it is built such that two cores may share execution units. The A520 is 22% more efficient than the A510, which was the other design objective. They are probably going to concentrate on background work on high-end chipsets.

While operating at the same frequency with the same amount of cache, a new chipset with X4, A720, and A520 cores in a 1+5+2 configuration would provide a 27% improvement on Geekbench 6’s multi-threaded test in comparison to a current 1+3+4 X3, A716, A510 CPU (i.e. before the node advantages of a new chip are accounted for).

The program operating on these cores will be tuned for ARMv9; take note that none of these cores supports the outdated 32-bit ARM instruction set. The Cortex-A710 core may be used by any business but it still needs business, to support 32-bit.

Industry-leading Architecture v9.2 Arm

The G720, the second generation Immortalis GPU for flagship handsets, was also announced by ARM. The new Mali-G720 and Mali-G620 are processors in the high-end and mid-range categories. The three GPUs introduce a brand-new architecture that is referred to as “5th Gen.”

The Delayed Vertex Shading pipeline is the main change in this generation. This modification lessens the demand for memory by 33% in Genshin Impact, 26% in Fortnite, and 41% in Elven Ruins, an Epic Games demo created to highlight the Unreal Engine.

The GPU may pick up the slack created by the memory load reduction, which also lowers power consumption and heat production. Overall, the performance per watt and peak performance may both be 15% greater with the 5th-generation design.

The Immortalis-G720 enhances ray tracing capability. To create Smart Global Illumination (SmartGI) as an industry standard, ARM is collaborating with Tencent Gaming and MediaTek.

Depending on what the creator of the chipset has intended, the Mali-G720 can be configured with between 6 and 9 cores, the Immortalis-G720 GPUs can have up to 10 cores, and the Mali-G620 can have up to 5 cores.

Early in 2024 and later this year, ARM new CPU and GPU architectures are expected. Interesting quotes from TSMC, Samsung, and Intel Foundry Services are included in the press release, which states that “the combination of cutting-edge Intel 18A technology with ARM’s newest and most powerful CPU core, the Cortex-X4, will create opportunities for companies looking to design the next generation of innovative mobile SoCs.” A third player in the foundry market has the chance to promote innovation and reduce costs.
