Key Differences
-
The Arc B580 has 4 GB more VRAM
Among all the differences on this page, 12 GB against 8 GB is one of the most meaningful, and it favors the Arc B580. Newer games tend to ask for more video memory, so the Arc B580’s extra VRAM helps the card age better.
-
The RTX 5050 has 60 W lower board power
The Arc B580 gives up a lot on total board power: 190 W, compared with 130 W on the RTX 5050. The RTX 5050 draws less power, which makes it easier to cool in compact cases.
-
The Arc B580 has 43% more memory bandwidth
Few buyers will miss this one. The Arc B580 brings 456 GB/s to the table; the RTX 5050 brings 320 GB/s. Memory bandwidth decides how quickly the GPU can feed itself with data, which matters most at 1440p and 4K.
-
The Arc B580 has a wider 192-bit memory bus
When it comes to memory bus, the Arc B580 wins comfortably with 192-bit against 128-bit. The Arc B580’s wider bus supports higher bandwidth, which helps most at high resolutions.

GPU & Performance
For gpu & performance, the spec sheet lists components and formats rather than figures we can rank. The table shows what the Arc B580 and the RTX 5050 each bring.
Memory
Arc B580 leads
The memory comparison is one-sided. The Arc B580 leads where it counts. On its side, the Arc B580 has 4 GB more VRAM. At high resolutions or with texture packs, running out of VRAM can hurt more than a small speed gap. Prioritize memory, and the Arc B580 is where you should land.
VRAM
Arc B580: 12 GB RTX 5050: 8 GB More VRAM lets the card hold higher-resolution textures and bigger scenes without stutter.
Memory bandwidth
Arc B580: 456 GB/s RTX 5050: 320 GB/s The Arc B580 has more bandwidth to work with, helping it hold up in memory-heavy games.

Power & Thermals
RTX 5050 leads
When it comes to power & thermals, the RTX 5050 is comfortably ahead. The RTX 5050 delivers 60 W lower board power. Higher board power often comes with higher performance, so the Arc B580’s appetite may be part of the price of its speed. Weighing only power & thermals, the RTX 5050 comes out ahead.
Total board power
Arc B580: 190 W RTX 5050: 130 W Lower board power means less heat, quieter cooling and a smaller impact on your electricity bill.
