Bandwidth basis
Intel ARK spec table: Graphics Memory Bandwidth 560 GB/s, together with Graphics Memory Speed 17.5 Gbps and Graphics Memory Interface 256 bit (17.5 Gbps x 256-bit / 8 = 560 GB/s, consistent)
Peak FLOPS
precisionint8tflops262denseyesvendor_claimyessource_idconsumer-intel-arc-a770-16gb-ark-specificationsbasisvendor-spec-sheetbasis_detailARK row GPU Peak TOPS (Int8) 262. Intel labels the Arc Pro B60 equivalent as peak throughput running XMX workloads with INT8 datatype and dense models, so this is read as dense INT8, not FP16 and not INT4.

notes
Desktop Alchemist part, 16 GB SKU only (an 8 GB A770 exists and is a different card). ARK: 32 Xe-cores, 512 Xe Vector Engines, 512 XMX engines, 32 ray-tracing units, 2100 MHz graphics clock, TSMC N6, TBP 225 W, PCIe 4.0 x16, device ID 0x56A0, launched Q3 2022. The only throughput figure printed is the dense INT8 262 TOPS row; no FP16, BF16 or FP8 number is published, so none is recorded. 16 GB at 560 GB/s holds a 7B-14B Q4 comfortably and a 32B Q4 only with tight KV headroom. No GPU-to-GPU fabric: the host link is the only interconnect.
