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’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 lists 504 GB/s. The RX 9070 has more bandwidth to work with, helping it hold up in memory-heavy games.
-
The RTX 4070 has 20 W lower board power
Think of it as a tiebreaker rather than a deal-breaker: 200 W for the RTX 4070, 220 W for the RX 9070. Lower board power means less heat, quieter cooling and a smaller impact on your electricity bill.
-
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.

GPU & Performance
Names, not numbers: the gpu & performance rows below show what each one is built with, and it’s worth reading them side by side.
Memory
RX 9070 leads
The RX 9070 clearly takes the memory round. The RX 9070 has the edge with 4 GB more VRAM. At high resolutions or with texture packs, running out of VRAM can hurt more than a small speed gap. For memory, the RX 9070 is the one to beat.
VRAM
RX 9070: 16 GB RTX 4070: 12 GB More VRAM lets the card hold higher-resolution textures and bigger scenes without stutter.
Memory bandwidth
RX 9070: 640 GB/s RTX 4070: 504 GB/s Bandwidth needs vary by architecture, so compare it alongside VRAM and cache rather than on its own.

In the features section, the key entries are names rather than numbers, so compare what the RX 9070 and the RTX 4070 list in the table below.
Power & Thermals
RTX 4070 leads
On power & thermals, the RTX 4070 comes out slightly ahead. In its favor, the RTX 4070 has 20 W lower board power. The RTX 4070 draws less power, which makes it easier to cool in compact cases. On power & thermals alone, the RTX 4070 gets the nod.
Total board power
RX 9070: 220 W RTX 4070: 200 W Higher board power often comes with higher performance, so the RX 9070’s appetite may be part of the price of its speed.

Frequently Asked Questions
Should I buy the RX 9070 or the RTX 4070?
The RX 9070 wins more of the areas we compared, so it’s the safer pick unless your top priority is 20 W lower board power.
Does the RX 9070 perform better than the RTX 4070?
It comes down to the chips: RDNA 4 in the RX 9070 versus Ada Lovelace in the RTX 4070. Our spec data lists them by name rather than by a single score.
Is the RX 9070 cheaper than the RTX 4070?
Going by launch prices, the RX 9070 costs $50 less than the RTX 4070. Prices as of March 2025; current offers may differ.
Executive Summary
Comparing the RX 9070 and the RTX 4070 feels a bit like comparing two good restaurants with different menus. The RX 9070 has 4 GB more VRAM, and for most people that’s not a small thing. Stack a wider 256-bit memory bus on top of that, and the RX 9070’s lead grows. That said, the RTX 4070 answers with 20 W lower board power, which some people will value more.
Fit matters more than scores here. The RX 9070 suits buyers focused on memory; the RTX 4070 suits those focused on power & thermals.
My pick: the RX 9070 gets my vote, but the RTX 4070 is the right call if you’d trade the rest for 20 W lower board power.
