Notes on 12 values — test conditions and caveats
  1. 1AMD Radeon RX 7900 XTX, Release date: First retail sale December 13, 2022; announced November 3, 2022.
  2. 2AMD Radeon RX 7900 XTX, Launch price: AMD's launch figure is the SEP (suggested e-commerce price); partner cards often sold higher.
  3. 3AMD Radeon RX 7900 XTX, Boost clock: Boost is a burst maximum; typical gaming runs near the 2300 MHz game clock.
  4. 4AMD Radeon RX 7900 XTX, Memory bandwidth: AMD also quotes 3500 GB/s 'effective' bandwidth with Infinity Cache; 960 GB/s is the raw VRAM figure.
  5. 5NVIDIA GeForce RTX 5070, Recommended PSU: NVIDIA's minimum for a PC with a Ryzen 9 9950X; other systems may need a different PSU.
  6. 6AMD Radeon RX 7900 XTX, Recommended PSU: AMD's 800W minimum assumes a Ryzen 9 5900X-class system; other builds may need more headroom.
  7. 7NVIDIA GeForce RTX 5070, Power connectors: One 16-pin 12V-2x6 socket; an adapter for two 8-pin cables comes in the box.
  8. 8AMD Radeon RX 7900 XTX, Power connectors: The reference card uses two 8-pin connectors.
  9. 9NVIDIA GeForce RTX 5070, DisplayPort version: DisplayPort 2.1b at the full UHBR20 rate.
  10. 10AMD Radeon RX 7900 XTX, DisplayPort version: DisplayPort 2.1 runs UHBR 13.5, up to 54Gbps of display link bandwidth per AMD.
  11. 11AMD Radeon RX 7900 XTX, Hardware encode: AMD's spec table marks 4K H264 Encode, H265/HEVC Encode and AV1 Encode all as Yes.
  12. 12AMD Radeon RX 7900 XTX, Video encoders: AMD describes a Dual Media Engine, i.e. two encode/decode engines, capable of simultaneous 8K60 HEVC streams.

Price and value

The NVIDIA GeForce RTX 5070 launches at $549, making it significantly cheaper than the AMD Radeon RX 7900 XTX at $999. That massive price gap allows buyers to save substantially while securing newer Blackwell architecture.

Buyers choosing the AMD card pay a steep premium for its higher launch price, though AMD's figure represents a suggested e-commerce price where partner cards often sold higher.

Memory and performance

The AMD Radeon RX 7900 XTX features 24 GB of GDDR6 video memory paired with a 384-bit memory bus width and 960 GB/s of raw VRAM bandwidth, plus a 96 MB last-level cache. That wide bus helps drive high-resolution textures smoothly.

By contrast, the NVIDIA GeForce RTX 5070 offers 12 GB of GDDR7 memory on a 192-bit bus. While its raw capacity is lower, its Gddr7 type hits a faster 28 Gbps speed and delivers a higher boost clock of 2,512 MHz.

Power and physical size

The NVIDIA GeForce RTX 5070 demands just 250 W of board power and requires a 650 W power supply for a system with a Ryzen 9 9950X. Its compact 242 mm length and 2-slot width easily fit smaller PC cases.

Meanwhile, the AMD Radeon RX 7900 XTX draws 355 W and calls for an 800 W power supply assuming a Ryzen 9 5900X-class system. It stretches to 287 mm in length and spans 2.5 slots, requiring much more room inside the chassis.

Connectivity and video encoding

The NVIDIA card includes PCIe 5.0 support alongside HDMI 2.1b and DisplayPort 2.1b outputs running at the full UHBR20 rate across three DisplayPort ports. It also features a single 12V-2x6 power connector.

The AMD card relies on PCIe 4.0 and provides two video encoders featuring a Dual Media Engine capable of simultaneous 8K60 HEVC streams, whereas the NVIDIA option includes one encoder.
