Arm Introduces its First Intel-Made CPUs: Neoverse CSS V3 and N3, Featuring Up to 128 Cores, DDR5, HBM3, and CXL 3.0

The Arm architecture has been with us for many years and, although initially used almost exclusively for low-power mobile processors, we have also seen many high-performance chips. In fact, some of the world’s leading companies are using Arm processors in their servers and data centers. Now, Arm has showcased the next generation of Neoverse CSS V3 and N3 cores to deliver improved performance in AI, cloud, and HPC.

Arm and x86 have been competing to cover the majority of devices on the market, as each architecture has its strengths and weaknesses. On one hand, Arm uses RISC (Reduced Instruction Set), and x86 relies on CISC (Complex Instruction Set). Broadly speaking, x86 is more capable of managing multiple tasks and doing so more quickly, resulting in higher raw performance. However, energy consumption is a problem, which is where Arm excels.

Arm presents its Neoverse CSS V3 platform with up to 128 cores per socket

This is the main reason why we have been seeing Arm processors mainly in low-power devices like mobiles and tablets, while x86 has been reserved for PC CPUs, laptops, and servers. Still, we have seen Apple switch entirely to Arm with their processors, which have proven to be quite competent in terms of power. Moreover, we also find Arm powering many-core CPUs with performance equal to or surpassing Intel and AMD server processors.

We should not underestimate Arm due to its significant presence in the mobile market, as its Neoverse cores are increasingly found in high-performance systems. In fact, NVIDIA Grace has been using Neoverse cores for years. Now, Arm has announced the launch of its Neoverse Compute Subsystem (CSS) for next-generation Neoverse N3 and V3 processors. The CSS is the platform used for Arm processor development and design, allowing processors to scale up to 128 cores per socket (CSS V3) supporting DDR5/LPDDR5 and HBM3 memory and compatible with PCIe 5.0 and CXL 3.0.

Arm Neoverse V3 achieves +84% AI performance, Neoverse N3 gains +196% compared to N2

Regarding these new processors, we have the Neoverse CSS N3, which allows for 8 to 32 cores per chip. This focuses on sectors such as cloud and DPU, achieving great energy efficiency with a 40W power consumption in the 32-core configuration. We also have the Neoverse CSS V3, which can reach up to 64 cores per chip.

Now it’s time to see the performance improvement gained with this new generation, starting with the Neoverse V3 achieving a 13% performance increase in Java and a 16% increase in SQL. In terms of AI, the performance boost is remarkable, with a +84% improvement with the Arm Neoverse V3 compared to V2. With the Neoverse N3, the difference is even greater, as we see a 30% additional performance in SQL and an impressive +196% increase in AI.

The news of Arm launching its first CPUs manufactured by Intel: Neoverse CSS V3 and N3, with up to 128 Cores, DDR5, HBM3, and CXL 3.0, first appears on El Chapuzas Informático.
