Montage’s fourth-generation Jintide CPU, with Intel’s fourth-generation Xeon Scalable Processor (code-named: Sapphire Rapids) as the core, passed Montage’s security pre-test (PrC) test, and is an x86 architecture server for the local market processor. Compared with the previous generation, the fourth-generation Jintide CPU adopts the Intel 7 process technology, with a maximum number of cores of 48 cores, a maximum turbo frequency of 4.2GHz, and a maximum shared cache of 105MB. The key performance indicators have been greatly improved.

At the same time, in terms of interconnection performance such as bandwidth, throughput, and delay, the fourth-generation Jintide CPU has achieved a series of breakthroughs or upgrades: UPI 2.0 is supported, the 4-way interconnection between CPUs is supported, and the rate is as high as 16GT/s; the memory type Upgraded to 8-channel DDR5 with a rate of up to 4800MT/s, 50% higher than DDR4, a single slot supports 16 memory sticks; supports PCIe 5.0, a single CPU supports a maximum of 80 PCIe channels, and a transfer rate of up to 32GT/s, which is higher than the previous generation Doubled to support higher-speed network cards, GPGPU cards and storage devices; the introduction of CXL 1.1 can support various accelerator cards and memory expansion, reducing the total cost of ownership of the data center while improving system performance.

The fourth-generation Jintide CPU has a built-in AI acceleration engine AMX (Advanced Matrix Extensions), which supports two data types widely used in the industry, INT8 and BFloat16, which can significantly improve the performance of artificial intelligence-related applications. The fourth-generation Jintide CPU also integrates four on-demand activation accelerators, DSA (Data Streaming Accelerator), QAT (Quick Assist Technology), DLB (Dynamic Load Balancer), and IAA (In-memory Analytics Accelerator). , which can realize the offloading of special tasks such as data analysis, cryptographic operations, data compression, and load balancing, and release CPU core computing power resources for key business applications, thereby improving the overall performance of the system.

At present, several server manufacturers have cooperated with Montage Technology to complete the research and development of server models based on the fourth-generation Jintide CPU.
