Intel Arc B770

The Intel Arc B770 is a desktop graphics card that launched in 2026. It is built on the Xe2-HPG GPU microarchitecture (codename BMG-G31) and is manufactured on a 5 nm process.

Memory

The Arc B770 has 16 GB of GDDR6 memory, with a 2,000 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 512 Gb/s, which affects how fast it can transfer data to and from memory. GPU memory stores temporary data that helps the GPU with complex math and graphics operations. More memory is generally better, as not having enough can cause performance bottlenecks.

Cores and Clock Speeds

The Arc B770 includes 4,096 shading units, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 2,100 MHz and can dynamically boost its clock speed up to 2,400 MHz. Complementing the processing units are 256 texture mapping units (TMUs) for efficient texture filtering and 128 render output units (ROPs) for pixel processing. Additionally, the GPU features 32 ray tracing units dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The Arc B770 occupies 2 PCIe expansion slots. It supports HDMI 2.1a, DisplayPort 2.1 display connections. Intel recommends a power supply of at least 550 W to handle the GPU's thermal design power (TDP) of 225 W.
