Notes on 6 values — test conditions and caveats
  1. 1AMD Radeon RX 9060 XT 16GB, Launch price: Launch MSRP was $349, but most 16GB models initially sold higher; Tom's Hardware saw them starting at $389.
  2. 2Intel Arc B580, DisplayPort version: Intel rates the DisplayPort outputs at DP 2.1 up to UHBR 13.5 (second output listed at UHBR 10).
  3. 3AMD Radeon RX 9060 XT 16GB, HDMI outputs: AMD sells no reference card; this is the reference-design I/O. Partner cards can differ (Sapphire Pulse: 2 HDMI, 1 DP).
  4. 4AMD Radeon RX 9060 XT 16GB, DisplayPort outputs: AMD sells no reference card; this is the reference-design I/O. Partner cards can differ (Sapphire Pulse: 2 HDMI, 1 DP).
  5. 5Intel Arc B580, Hardware encode: Intel's spec table also lists H.264 and H.265 (HEVC) hardware encode as Yes.
  6. 6Intel Arc B580, Card height: Intel publishes this dimension as the card's 'Width' (115 mm) alongside the 272 mm length.

Performance and Efficiency

The AMD card features the Rdna 4 architecture with a higher boost clock of 3,130 MHz, while the Intel competitor utilizes the Xe2 architecture with 2,560 shader cores. For power delivery, the AMD option requires a modest 450 W system power supply and draws 160 W, making it easier on older power units.

In contrast, the Intel B580 demands a 600 W recommended PSU and reaches 190 W of board power. Both cards connect using a standard 8-pin power connector.

Memory and Architecture

The AMD Radeon board offers 16 GB of Gddr6 video memory paired with a 32 MB last-level cache and a faster memory speed of 20 Gbps. This larger buffer helps handle demanding texture loads at high resolutions.

The Intel Arc B580 counters with a 192-bit memory bus width and a memory bandwidth of 456 GB/s, outpacing the AMD 128-bit bus and 320 GB/s bandwidth. Both utilize Gddr6 memory types.

Connectivity and Displays

The AMD card takes the lead in interface technology with PCIe 5.0 and 16 lanes, compared to the PCIe 4.0 and 8 lanes on the Intel alternative. This allows for faster data transfer with compatible motherboards.

For monitor setups, the Intel B580 supports up to 4 displays through three DisplayPort outputs and one HDMI port. The AMD rival manages up to 3 displays via two DisplayPort outputs and one HDMI port.
