Huawei Atlas 300I A2 product page (e.huawei.com) - 技术规格 table publishing 560 TOPS INT8 / 280 TFLOPS FP16 (this SKU has NO record in data/accelerators)

VERBATIM 2026-10-05 via web_extract. Recorded as the vendor document for a 310-generation inference SKU that data/accelerators/ does not cover at all, and as the scale calibration for the Atlas 300I Duo figures. THE 技术规格 TABLE, verbatim, in full: | 产品 | Atlas 300I A2 | | 形态 | 双槽位全高全长PCIe卡 | | AI算力 | 560 TOPS INT8，280 TFLOPS FP16 | | CPU | 8 core * 2.0 GHz | | 片上内存 | 32 GB，带宽0.8 TB/s，支持ECC<br>64 GB，带宽1.6 TB/s，支持ECC | | PCIe接口 | PCIe 5.0 | | 功耗 | 最大350W | | 散热方式 | 被动风冷 | | 风扇 | 每个抽屉集成5个热拔插风扇模组，支持4+1冗余 | | 工作环境温度 | 5℃~45℃（41℉～113℉） | | 结构尺寸（高×宽×深） | 266.7mm * 39.04mm * 111.15mm | and from 概述, verbatim: '支持最高560 TOPS INT8 和 280 TFLOPS FP16算力'; 特性: '提供业界领先的560 TOPS INT8算力', '提供业界领先的280 TFLOPS FP16算力', '支持 8 core * 2.0 GHz CPU计算能力', '最大支持1.6 TB/s内存带宽', '支持PCIe 5.0高速接口'. THE CALIBRATION THIS SUPPLIES. The Atlas 300I Duo is the dual-Ascend card at 280 TOPS INT8 / 140 TFLOPS FP16, and the Atlas 300I A2 is exactly 2x it at 560/280 - consistent with the Duo being two 310-class processors and the A2 being two newer ones at double the per-processor rate. This is the first point in the 310 line where Huawei has published a per-card INT8 figure at all in this slice, and it sets the ceiling: the 300I Pro (24GB) and 300V Pro (48GB) publish NO compute figure on any Huawei page located on this pass, while the Duo and A2 do. So the honest statement is per-SKU, not per-generation. The memory row is also worth recording because it is a CAPACITY-PAIR under one bandwidth column: 32 GB at 0.8 TB/s or 64 GB at 1.6 TB/s, ECC, both bins published for the same SKU. A record must pick one bin and say which, not average them. SPARSITY: no footnote, no '2:4', no '稀疏'. Do not halve 560 or 280. A COLOUR SHEET also exists for this part and was located but NOT read: '昇腾Atlas 300I A2 推理卡产品彩页' at https://e.huawei.com/cn/documents/products/computing/799a9236e96a48b7aa126b10f3d7be97, whose PDF is at e-file.huawei.com/.../%E6%98%87%E8%85%BEAtlas%20300I%20A2%20%E6%8E%A8%E7%90%86%E5%8D%A1%E4%BA%A7%E5%93%81%E5%BD%A9%E9%A1%B5.pdf (0.4MB). The e.huawei.com viewer page renders no extractable text and the download requires a session, so the web page above is the citable document here. Recorded so a future pass knows the colour sheet exists and is the next document to try if the product page is ever withdrawn.
