Arm announced four new CPUs under the Arm C1 family and one new GPU under the G1 family. All of these CPUs and GPUs are built under the new Armv9.3 architecture for next-generation processors.
Arm C1 replaces the long-standing Cortex CPUs. Arm C1-Ultra is the most powerful CPU replacing the Cortex-X925 family. It offers 25% faster performance than Cortex-X925.
Next is Arm C1-Premium which is a new CPU targeting affordable premium devices. It is 3% smaller in size than C1-Ultra but offers better power efficiency.
Arm C1-Pro is a mid-range CPU replacing the Cortex-A725. In terms of performance, it receives a 16% performance increase and reduces power consumption by up to 12% for playing videos and browsing websites.
The last CPU is the Arm C1-Nano which emphasizes low power consumption replacing the Cortex-A520. It improves power efficiency by up to 26% with a 2% smaller size.
All of these Arm C-1 CPUs can be integrated into SOCs with configurations ranging from 1 to 14 CPU cores depending on the customer. Arm says that overall, a chip with Arm C-1 can provide an overall performance increase of up to 30%, is up to 15% faster and consumes up to 12% less power than the previous generation.
Meanwhile, the ARM Mali G1-Ultra GPU uses the second generation Ray Tracing Unit (RTUv2) which increases ray tracing performance by up to two times compared to the Immortalis-G925. With this, frame rates can increase by up to 40%, power efficiency increases by 9% and it can also perform artificial intelligence (AI) task inference by up to 20% better.
Like the Arm C-1 CPU, the Mali G1-Ultra is also offered in configurations of 1-24 shader cores depending on customer needs. It supports Arm's Accuracy Super Resolution (ASR) feature which increases frame rates similar to FSR and DLSS on gaming GPUs. So far, ASR is already supported in Unreal Engine 5.
