Intel Arc Pro B60 vs B70 vs B60 Dual 48GB: Which One Should You Actually Buy?
We stock all three Arc Pro cards, so we have no incentive to steer you to the wrong one: whichever fits, we sell it to you. Here is the actual decision, in the order the trade-offs matter.
The three cards side by side
| Card | VRAM | Memory bandwidth | Model sweet spot (Q4) | Price |
|---|---|---|---|---|
| B60 24GB | 24GB | 456 GB/s | 7B to 14B | £899.99 |
| B70 32GB | 32GB | 608 GB/s | 13B to 34B | £1,549.99 |
| B60 Dual 48GB | 48GB (2x24, dual-die) | 456 GB/s per die | 70B-class | £1,699.99 |
The decision, honestly
Buy the B60 24GB if you are one person running 7B to 14B models: local assistants, coding models, most day-to-day homelab work. Standard card, fits any x16 slot, no complications. The cheapest working seat at the table.
Buy the B70 32GB if you want the fastest single-GPU experience on mid-size models. This is the detail most buyers miss: the B70 has the highest memory bandwidth of the three (608 GB/s vs 456), and memory bandwidth is what sets tokens per second in local inference. A 14B or 32B model runs faster on a B70 than on either B60. It is also a normal single-die card, so no motherboard requirements. Newegg's best-selling workstation GPU in the US for a reason.
Buy the B60 Dual 48GB if the model size is the point: 70B-class quantized models on one card, or serving a team via vLLM across both dies. Two conditions, stated plainly: your motherboard must support PCIe x8/x8 bifurcation (check before you buy), and each die has 456 GB/s, so a model that fits on the B70 will run faster on the B70. The Dual wins when 32GB is not enough.
The two-question shortcut
1. What is the biggest model you genuinely need? Up to 14B: B60 24GB. Up to 34B: B70. 70B-class: Dual. (Full sizing: the VRAM guide.)
2. Speed or headroom? If you are torn between B70 and Dual at £150 apart: B70 is the faster experience for models that fit in 32GB; the Dual is the only way to 48GB. Choose the model, not the number.
