Workstation GPU with 32GB GDDR6

The ASRock Intel B65 CT 32G is a workstation graphics card built on the Intel Arc Pro B65 GPU. It targets professionals who need large frame-buffer capacity for rendering, simulation or multi-display workflows in a dual-slot ATX form factor.

PCI Express 5.0 x16 interface limits

The card connects through a PCI Express 5.0 x16 slot, providing high host bandwidth for compute and data transfer. System performance will be constrained if the motherboard or CPU only supports earlier PCIe generations, reducing available throughput for memory-intensive tasks.

32GB capacity and 256-bit memory interface

The 32GB GDDR6 memory on a 256-bit bus handles large datasets, high-resolution textures and up to four 7680 x 4320 displays. Workloads that exceed 32GB of VRAM or demand memory bandwidth beyond the 256-bit interface will encounter bottlenecks.

Questions about this item

Should I pick the 32GB model or is a smaller capacity available for this card?

This model is offered only with 32GB of GDDR6 memory on a 256-bit bus; no lower-capacity version is listed for the B65 CT.

What does the 2400MHz core clock deliver in an actual workstation build?

The 2400MHz boost clock drives the Arc Pro B65 GPU and its 160 XMX engines through PCIe 5.0 x16, giving consistent compute throughput for rendering and AI workloads.

How does the PCIe 5.0 x16 interface limit performance in practice?

The x16 link provides full 5.0 bandwidth to the CPU and chipset, so the 200W board can saturate the bus without throttling during heavy multi-display or compute tasks.
