Intel Arc B580
The Intel Arc B580 is a desktop graphics card released in December 2024. It is built for budget-conscious gamers and creators seeking modern hardware acceleration.
- Release date
- 2024-12
- Launch price
- 249 USD
- Shader cores
- 2,560 cores
- Video memory
- 12 GB
- Memory type
- Gddr6
- Memory bus width
- 192 bit
Memory and Performance Specs
The B580 arrives with 12 GB of video memory operating across a 192-bit bus. This configuration hits a memory bandwidth of 456 GB/s at 19 Gbps speeds, supported by an 18 MB last-level cache.
Driving the card are 2,560 shader cores based on the Xe2 architecture. The boost clock hits 2,670 MHz, though Intel leaves the base clock and FP32 compute figures unpublished.
Power and System Requirements
Power consumption sits at a board power of 190 W. To keep the system stable, Intel recommends a 600 W power supply unit, and the card draws power through a single 8-pin connector.
For motherboard connectivity, the unit uses PCIe 4.0 across 8 lanes. Buyers should check their motherboard slot availability to ensure proper compatibility.
Display Outputs and Video Engine
Physical dimensions measure 272 mm in length and 115 mm in height, occupying 2 slots in a chassis. The rear panel features 1 HDMI 2.1 port alongside 3 DisplayPort 2.1 outputs, capped at UHBR 13.5 for the first output and UHBR 10 for the second, driving up to 4 displays total.
Video workflows benefit from 2 hardware encoders capable of H.264, HEVC, and AV1 encoding.
