Notes on 5 values — test conditions and caveats
  1. 1NVIDIA GeForce RTX 5070, Recommended PSU: NVIDIA's minimum for a PC with a Ryzen 9 9950X; other systems may need a different 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 5070, Power connectors: One 16-pin 12V-2x6 socket; an adapter for two 8-pin cables comes in the box.
  4. 4NVIDIA 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.
  5. 5NVIDIA GeForce RTX 5070, DisplayPort version: DisplayPort 2.1b at the full UHBR20 rate.

Price and Value

The NVIDIA GeForce RTX 5070 arrives at a much more accessible launch price of $549, making it significantly easier on the wallet than the NVIDIA GeForce RTX 4080 Super at $999. Buyers focused on upfront cost will find the 5070 much more appealing.

Despite the lower price, the RTX 5070 introduces newer Blackwell architecture alongside faster GDDR7 memory running at 28 Gbps. This delivers modern efficiency without demanding the premium price tag attached to the older Ada Lovelace flagship.

FAQ

What power supply do I need for the RTX 5070 versus the RTX 4080 Super?

NVIDIA recommends a minimum 650 W power supply for the RTX 5070 based on a Ryzen 9 9950X system, while the RTX 4080 Super calls for a 750 W minimum assuming a Ryzen 9 5900X system.

Which graphics card is physically smaller?

The RTX 5070 is significantly smaller, measuring 242 mm long, 112 mm high, and taking up 2 slots, whereas the RTX 4080 Super measures 304 mm long, 137 mm high, and requires 3 slots.

What type of video memory does each card use?

The RTX 5070 uses faster GDDR7 memory operating at 28 Gbps across a 192-bit bus, while the RTX 4080 Super uses GDDR6X memory at 23 Gbps across a wider 256-bit bus.

Do both cards support AV1 video encoding?

Yes, both graphics cards feature hardware-accelerated AV1 encoding, though the RTX 4080 Super includes 2 hardware encoders compared to 1 encoder on the RTX 5070.
