NVIDIA GeForce RTX 5050vsIntel Arc B580: Head to Head

Both cards share the same $249 launch price and core shader count, yet they take very different approaches to memory and power consumption. Choosing between them depends on whether you prioritize video memory capacity or power efficiency and modern interface standards.

Notes on 6 values — test conditions and caveats
  1. 1NVIDIA GeForce RTX 5050, Recommended PSU: NVIDIA's 550 W minimum assumes a Ryzen 9 9950X system; requirements vary with your configuration.
  2. 2NVIDIA GeForce RTX 5050, Power connectors: Native input is one 8-pin; NVIDIA's 300 W+ PCIe Gen 5 PSU-cable option works via the in-box adapter.
  3. 3NVIDIA GeForce RTX 5050, DisplayPort version: NVIDIA specifies UHBR20 on these DisplayPort 2.1b outputs.
  4. 4Intel Arc B580, DisplayPort version: Intel rates the DisplayPort outputs at DP 2.1 up to UHBR 13.5 (second output listed at UHBR 10).
  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.

Memory and Performance

The Intel Arc B580 delivers significantly more video memory with 12 GB paired with a 192-bit memory bus width, driving a memory bandwidth of 456 GB/s. This setup handles heavy asset loads comfortably compared to the NVIDIA GeForce RTX 5050, which relies on 8 GB of video memory on a 128-bit bus width.

At the same time, the RTX 5050 fights back with a faster memory speed of 20 Gbps and a higher boost clock of 2,570 MHz. Buyers focusing on raw bandwidth and memory capacity will find the Intel card more appealing for demanding textures.

Power and Efficiency

Power consumption splits these two competitors cleanly. The RTX 5050 requires a board power of just 130 W and a recommended PSU of 550 W, making it much easier to fit into tighter builds.

In contrast, the Arc B580 demands a higher board power of 190 W and a 600 W recommended PSU. This higher energy draw means the NVIDIA option runs cooler and places less strain on your system power supply.

Connectivity and Video

The RTX 5050 pulls ahead with modern interface support, offering PCIe 5.0 and HDMI 2.1b alongside three DisplayPort 2.1b outputs featuring UHBR20 support. The Arc B580 sticks with PCIe 4.0 and HDMI 2.1, while its DisplayPort 2.1 outputs max out at UHBR 13.5 and UHBR 10.

For video creators, the Arc B580 features two hardware encoders supporting H.264, HEVC, and AV1, doubling the single encoder found on the NVIDIA card. Content creators editing multi-stream video benefit directly from Intel's dual encoder setup.

Dimensions and Build

Physical dimensions matter when fitting these cards into standard desktop cases. The Arc B580 measures 272 mm in card length, 115 mm in card height, and spans 2 slots in width.

NVIDIA leaves the card dimensions unpublished for the RTX 5050, leaving builders to check individual partner card specifications before purchasing. The NVIDIA card uses an 8-pin power connector via an in-box adapter for its PCIe Gen 5 PSU-cable option, matching the native 8-pin input on the Intel card.
