Centaur frigiver dybdegående analyse fra Linley Group for sin NCORE-udstyrede x86-processor



Centaur Technology today revealed in-depth information about its new processor-design technology for integrating high-performance x86 CPUs with a specialized co-processor optimized for artificial intelligence (AI) acceleration. On its website, Centaur provides a new independent report from The Linley Group, the industry's leading authority on microprocessor technology and publishers of Microprocessor Report. The Linley Group reviewed Centaur's detailed design documents and interviewed Centaur's CPU and AI architects to support the analysis of both Centaur's newest x86 microarchitecture and the AI co-processor design.

'Centaur galopperer tilbage til x86-markedet med et innovativt processor-design, der kombinerer otte højeffektive CPU'er med en brugerdefineret deep-learning accelerator (DLA). Virksomheden er den første, der annoncerer et server-processor-design, der integrerer en DLA. Den nye accelerator, kaldet Ncore, leverer bedre ydelser på neuralt netværk end endda den mest kraftfulde Xeon, men uden de høje omkostninger ved et eksternt GPU-kort, ”udtaler Linley Gwennap, chefredaktør, mikroprosessorrapport. Rapporten kan fås her (PDF).

Linley Group henviste til certificerede MLPerf benchmark-scoringer (Preview) for at sammenligne Centaur's AI-ydeevne med high-end x86 CPU-kerner fra den førende x86-leverandør. Baseret på MLPerf-scoringer kan Centaurs AI-coprocessor-inferences ydeevne sammenlignes med 23 af Intels verdensklasse x86-kerner, der nu understøtter 512-biters neurale netværksinstruktioner (VNNI). Centaurs AI-co-processor bruger en arkitektonisk lignende enkelt-instruktion-multiple-data (SIMD) tilgang som VNNI, men knaser 32.768 bit i en enkelt urcyklus ved hjælp af en 16 MB hukommelse med 20 terabyte / sek båndbredde. Desuden forbliver x86 CPU-kernerne tilgængelige til andre, mere generelle opgaver ved at aflaste inferensbehandling til en specialiseret co-processor. Applikationsudviklere kan innovere nye algoritmer, der drager fordel af den uovertrufne inferens latency, der er aktiveret af Centaurs AI-ydelse og stramme integration med x86 CPU'er.

Attendees at the ISC East trade show in NYC saw Centaur's new technology up close for the first time. The demo showcased video analytics using Centaur's reference system with x86-based network-video-recording (NVR) software from Qvis Labs. In addition to conventional, real-time object detection/classification, Centaur was the only vendor at the show to highlight leading-edge applications such as semantic segmentation (pixel-level image classification) and a new technique for human pose estimation ('stick figures'). Centaur is focused on improving the hardware price/performance and software productivity for platforms to support this next wave of research applications and speed deployment into new server-class products.
