Key Differences
-
The RX 9070 has 4 GB more VRAM
If vram is one of your priorities, this settles it: the RX 9070 leads clearly with 16 GB to the RTX 4070 Super’s 12 GB. Newer games tend to ask for more video memory, so the RX 9070’s extra VRAM helps the card age better.
-
The RX 9070 has 27% more memory bandwidth
The numbers aren’t close. The RX 9070 lists 640 GB/s for memory bandwidth, while the RTX 4070 Super lists 504 GB/s. Bandwidth needs vary by architecture, so compare it alongside VRAM and cache rather than on its own.
-
The RX 9070 has a wider 256-bit memory bus
A clear win for the RX 9070: 256-bit against 192-bit. Few specs in this matchup are as one-sided. The RX 9070’s wider bus supports higher bandwidth, which helps most at high resolutions.
Design & Size
Size & Connectivity

GPU & Performance
The RX 9070 and the RTX 4070 Super differ on gpu & performance in ways that are described rather than measured. The table has the details.
Memory
RX 9070 leads
The memory comparison is one-sided. The RX 9070 leads where it counts. The RX 9070 takes this one with 4 GB more VRAM. More VRAM lets the card hold higher-resolution textures and bigger scenes without stutter. For memory, the RX 9070 is the one to beat.
VRAM
RX 9070: 16 GB RTX 4070 Super: 12 GB At high resolutions or with texture packs, running out of VRAM can hurt more than a small speed gap.
Memory bandwidth
RX 9070: 640 GB/s RTX 4070 Super: 504 GB/s Memory bandwidth decides how quickly the GPU can feed itself with data, which matters most at 1440p and 4K.
Features
The features comparison is about what’s inside rather than how much. See the table for the RX 9070’s and the RTX 4070 Super’s entries.
Power & Thermals
Too close to call
You can skip ahead if power & thermals was your deciding factor: the two are evenly matched here. The power & thermals verdict: no winner, and no reason to worry either way.
