Huawei CloudMatrix AI efficiency has achieved what the corporate claims is a major milestone, with inner testing exhibiting its new knowledge centre structure outperforming Nvidia’s H800 graphics processing models in working DeepSeek’s superior R1 synthetic intelligence mannequin, in accordance with a completetechnical paperlaunched this week by Huawei researchers.
The analysis, carried out by Huawei Technologies in collaboration with Chinese AI infrastructure startup SiliconFlow, supplies what seems to be the primary detailed public disclosure of efficiency metrics for CloudMatrix384.
However, it’s vital to notice that the benchmarks had been carried out by Huawei on its techniques, elevating questions on impartial verification of the claimed efficiency benefits over established business requirements.
The paper describes CloudMatrix384 as a “next-generation AI datacentre architecture that embodies Huawei’s vision for reshaping the foundation of AI infrastructure.” While the technical achievements outlined seem spectacular, the dearth of third-party validation means outcomes needs to be seen within the context of Huawei’s persevering with efforts to exhibit technological competitiveness outdoors of US sanctions.
The CloudMatrix384 structure
CloudMatrix384 integrates 384 Ascend 910C NPUs and 192 Kunpeng CPUs in a supernode, linked by an ultra-high-bandwidth, low-latency Unified Bus (UB).
Unlike conventional hierarchical designs, a peer-to-peer structure allows what Huawei calls “direct all-to-all communication,” permitting compute, reminiscence, and community assets to be pooled dynamically and scaled independently.
The system’s design addresses notable challenges in creating trendy AI infrastructure, significantly for mixture-of-experts (MoE) architectures and distributed key-value cache entry, thought of important for big language mannequin operations.
Performance claims: The numbers in context
The Huawei CloudMatrix AI efficiency outcomes, whereas carried out internally, current spectacular metrics on the system’s capabilities. To perceive the numbers, it’s useful to consider AI processing like a dialog: the “prefill” section is when an AI reads and ‘understands’ a query, whereas the “decode” section is when it generates its response, phrase by phrase.
According to the corporate’s testing, CloudMatrix-Infer achieves a prefill throughput of 6,688 tokens per second per processing unit, and 1,943 tokens per second when producing a response.
Think of tokens as particular person items of textual content – roughly equal to phrases or elements of phrases that the AI processes. For context, this implies the system can course of hundreds of phrases per second on every chip.
The “TPOT” measurement (time-per-output-token) of below 50 milliseconds means the system generates every phrase in its response in lower than a twentieth of a second – creating remarkably quick response occasions.
More considerably, Huawei’s outcomes correspond to what it claims are superior effectivity rankings in contrast with competing techniques. The firm measures this by way of “compute efficiency” – primarily, how a lot helpful work every chip accomplishes relative to its theoretical most processing energy.
Huawei claims its system achieves 4.45 tokens per second per TFLOPS for studying questions and 1.29 tokens per second per TFLOPS for producing solutions. In perspective, TFLOPS (trillion floating-point operations per second) measures uncooked computational energy – akin to the horsepower score of a automotive.
Huawei’s effectivity claims recommend its system does extra helpful AI work per unit of computational horsepower than Nvidia’s competing H100 and H800 processors.
The firm studies sustaining 538 tokens per second below the stricter timing necessities of sub-15 milliseconds per phrase.
However, the spectacular numbers lack impartial verification from third-parties, customary follow for validating efficiency claims within the expertise business.
Technical improvements behind the claims
The reported Huawei CloudMatrix AI efficiency metrics stem from a number of technical particulars quoted within the analysis paper. The system implements what Huawei describes as a “peer-to-peer serving architecture” that disaggregates the inference workflow into three subsystems: prefill, decode, and caching, enabling every element to scale primarily based on workload calls for.
The paper posits three improvements: a peer-to-peer serving structure with disaggregated useful resource swimming pools, large-scale knowledgeable parallelism supporting as much as EP320 configuration the place every NPU die hosts one knowledgeable, and hardware-aware optimisations together with optimised operators, microbatch-based pipelining, and INT8 quantisation.
Geopolitical context and strategic implications
The efficiency claims emerge in opposition to the backdrop of intensifying US-China tech tensions. Huawei founder Ren Zhengfei acknowledged just lately that the corporate’s chips nonetheless lag behind US opponents “by a generation,” however mentioned clustering strategies can obtain comparable efficiency to the world’s most superior techniques.
Nvidia CEO Jensen Huang appeared to validate this throughout a latest CNBC interview, stating: “AI is a parallel problem, so if each one of the computers is not capable… just add more computers… in China, [where] they have plenty of energy, they’ll just use more chips.”
Lead researcher Zuo Pengfei, a part of Huawei’s “Genius Youth” program, framed the analysis’s strategic significance, writing that the paper goals “to build confidence in the domestic technology ecosystem in using Chinese-developed NPUs to outperform Nvidia’s GPUs.”
Questions of verification and business influence
Beyond the efficiency metrics, Huawei studies that INT8 quantisation maintains mannequin accuracy similar to the official DeepSeek-R1 API in 16 benchmarks in inner, unverified assessments.
The AI and expertise industries will possible await impartial verification of Huawei’s CloudMatrix AI efficiency earlier than drawing definitive conclusions.
Nevertheless, the technical approaches described recommend real innovation in AI infrastructure design, providing insights for the business, whatever the particular efficiency numbers.
Huawei’s claims – whether or not validated or not – spotlight the depth of competitors in AI {hardware} and the various approaches corporations take to realize computational effectivity.
