Intel Arc Pro buyers debate B60, B70

Two B60s only win if your stack can actually use both GPUs; otherwise the B70’s extra cores, bandwidth, x16 link, and 32GB ECC memory make it the cleaner all-around buy.

• –B70: 32 Xe-cores, 367 INT8 TOPS, 608 GB/s bandwidth, PCIe 5.0 x16, 32GB GDDR6 ECC
• –B60: 20 Xe-cores, 197 INT8 TOPS, 456 GB/s bandwidth, PCIe 5.0 x8, 24GB GDDR6; two cards give more aggregate VRAM, not a magically shared pool
• –Both cards have 2 multi-format codec engines plus AV1/H.264/H.265 encode/decode, so dual B60s help more with total stream count than with one stream’s latency
• –Intel’s own MLPerf notes say a 4-GPU B70/B65 system can reach 128GB VRAM and the B70 can be up to 1.8x faster than the B60 in inference, which is a good sign that the bigger card matters
• –If you want the least risky purchase against Intel’s still-maturing tooling, the B70 is the safer bet; if you want maximum flexibility for future multi-GPU AI rigs, dual B60s remain the capacity play
