The short version

The Gaming OC 16G runs the 16 GB GeForce RTX 5080 at 2730 MHz (reference 2617 MHz) in a 340 x 140 x 70 mm Windforce card with a dual BIOS and RGB Halo lighting. It needs a 16-pin connector and an 850 W supply. It suits 4K gamers wanting a high factory clock; the caveats are size, price over the chip's list and only 16 GB of memory.

Pros

  • 2730 MHz boost versus a 2617 MHz reference
  • Dual BIOS (Performance and Silent) and RGB Halo
  • 4-year warranty with online registration
  • Server-grade thermal gel on memory and MOSFETs

Cons

  • 340 mm long and 70 mm thick
  • Only 16 GB of VRAM
  • Single HDMI port

What reviewers and owners say

  • Tom's Hardware

    Mixed

    Founders Edition review, so it speaks to the chip: finds a cool, quiet second-fastest Blackwell part, but only small gains over the RTX 4080 Super outside of frame generation, plus 16 GB of memory and inflated retail pricing.
