Notes on 5 values — test conditions and caveats
  1. 1NVIDIA GeForce RTX 5080, Recommended PSU: NVIDIA's minimum for a PC with a Ryzen 9 9950X; it recommends a PCIe CEM 5.1 compliant PSU.
  2. 2NVIDIA GeForce RTX 4080 Super, Recommended PSU: NVIDIA's 750 W minimum assumes a PC with a Ryzen 9 5900X; needs vary by configuration.
  3. 3NVIDIA GeForce RTX 4080 Super, Power connectors: Card takes a 16-pin 12V-2x6 connector; a 3x PCIe 8-pin adapter ships in the box for PSUs without a PCIe Gen 5 cable.
  4. 4NVIDIA GeForce RTX 5080, DisplayPort version: DisplayPort 2.1b at UHBR20 on all three DP outputs.
  5. 5NVIDIA GeForce RTX 5080, Slot width: The card is 2-slot (40 mm thick), but NVIDIA's install guide asks for 3-slot (61 mm) case clearance.

Performance and Architecture

The RTX 5080 introduces the Blackwell architecture, yielding more shader cores and a higher boost clock than the Ada Lovelace design in the RTX 4080 Super. This translates to higher FP32 compute capability, giving the newer card an edge in heavy rendering tasks.

Buyers focused on maximum frame rates and faster compute processing will find the RTX 5080 provides a noticeable upgrade in raw computational capacity.

Memory and Interface

While both cards feature 16 GB of video memory on a 256-bit bus, the RTX 5080 upgrades to Gddr7 memory. This pushes memory speed to 30 Gbps and bandwidth to 960 GB/s, vastly outpacing the older GDDR6X standard.

Furthermore, the RTX 5080 supports PCIe 5.0, doubling the interface bandwidth potential compared to the PCIe 4.0 standard found on the RTX 4080 Super.

Power and Physical Design

Power consumption increases on the newer model, with the RTX 5080 demanding 360 W and an 850 W recommended PSU, compared to 320 W and a 750 W PSU for the RTX 4080 Super. Both units rely on the 12V-2x6 power connector.

In terms of physical space, both cards measure 304 mm in length and 137 mm in height. However, the RTX 5080 features a 2-slot width design, whereas the RTX 4080 Super takes up 3 slots.

Display and Video Features

For display connections, the RTX 5080 upgrades to DisplayPort 2.1b at UHBR20 and HDMI version 2.1b, offering superior display output standards over the DisplayPort 1.4a and HDMI 2.1a on the RTX 4080 Super.

In the video engine department, the RTX 5080 adds H.264 and HEVC hardware encoding alongside AV1, whereas the older model is limited to AV1 encoding, while both maintain 2 encoders.
