As originally reported by two Chinese publications, Pandaily (opens in new tab) and ScienceNet (opens in new tab), the chip is the product of work at the DAMO Academy (short for Discovery, Adventure, Momentum and Outlook), a research and development (R&D) unit at Alibaba.
If reports are to be believed, the novel architecture allows the processor to overcome the infamous von Neumann bottleneck, which describes the speed limitations created by the internal bus that passes data between the processor and memory.
TechRadar Pro asked Alibaba for confirmation of these claims and further detail about the new chip, but did not receive an immediate response.
Various workarounds for the von Neumann bottleneck have been developed by semiconductor designers, such as deploying cache memory between the CPU and main memory. The architecture of Apple’s M1 series of chips, meanwhile, bypasses the issue by placing the processor and memory on a single system-on-chip (SoC).
However, for computers with discrete processing and memory (which encompasses most personal devices), the bottleneck continues to pose considerable challenges. A chip that could address this problem, then, would inevitably be in high demand.
However, although very little is known about the new Alibaba chip (including its name), it’s unlikely to make its way to consumer devices. Instead, it will almost certainly be deployed in support of Alibaba’s bare metal and dedicated server offerings, which have been a main focus for the firm over the last couple of years.
As noted by The Register (opens in new tab), the company is also set to deliver a presentation on “3D logic-to-DRAM hybrid bonding” as part of a series on machine learning chips for emerging applications at a semiconductor conference next year, which offers another clue as to potential use cases.
The mysterious new chip is by no means the company’s only exciting project in the semiconductor space, either. In October, Alibaba Cloud unveiled a custom Arm-based server CPU called the Yitian 710, which boasts a whopping 60 billion transistors and 128 cores.
For context, Apple’s most performant processor (the M1 Max) has 57 billion transistors, while top-tier AWS Graviton 2 and AMD EPYC Rome server CPUs have roughly 30 and 40 billion transistors, respectively.
During the same event, Alibaba also announced it will be devoting more resources to building custom-built processors based on the open-source RISC-V architecture, in what looks like an attempt to move away from proprietary compute architectures.
