RX 9070 XT vs RTX 5070: Which Is Better?
Shopping across brands means comparing different philosophies. The RX 9070 XT and the RTX 5070 show how AMD and NVIDIA each approach the upper-midrange graphics card class. The spec sheets tilt toward the RX 9070 XT, which leads in 1 of 2 areas and opens its biggest gap on memory. Here’s what the numbers say, and what they mean for you.

Key Differences
-
The RX 9070 XT has 4 GB more VRAM
The spread here is large: 16 GB on the RX 9070 XT versus 12 GB on the RTX 5070. Expect to notice it. Newer games tend to ask for more video memory, so the RX 9070 XT’s extra VRAM helps the card age better.
-
The RTX 5070 has 54 W lower board power
Of all the specs we compared, this is one where the RTX 5070 makes its strongest case: 250 W against 304 W. Lower board power means less heat, quieter cooling and a smaller impact on your electricity bill.
-
The RX 9070 XT has a wider 256-bit memory bus
The RX 9070 XT clearly leads on memory bus, and 256-bit versus 192-bit is a difference that reaches well beyond the spec sheet. The RX 9070 XT’s wider bus supports higher bandwidth, which helps most at high resolutions.
-
The RTX 5070 has a smaller 650 W PSU requirement
On recommended psu, the RTX 5070 posts 650 W against 750 W for the RX 9070 XT, a gap big enough to feel in everyday use. Recommendations include a safety margin for the rest of the system, so they’re a guide rather than a hard limit.
-
The RTX 5070 has 5% more memory bandwidth
If everything else were equal, this small edge would favor the RTX 5070: 672 GB/s against 640 GB/s. Bandwidth needs vary by architecture, so compare it alongside VRAM and cache rather than on its own.

GPU & Performance
We don’t score this area directly, because the gpu & performance specs are labels rather than measurements. The table shows what each lists.
Memory
RX 9070 XT leads
The RX 9070 XT dominates the memory section, and the gaps are large enough to matter in daily use. The RX 9070 XT gives you 4 GB more VRAM. More VRAM lets the card hold higher-resolution textures and bigger scenes without stutter. On its side, the RTX 5070 has 5% more memory bandwidth. Prioritize memory, and the RX 9070 XT is where you should land.
VRAM
RX 9070 XT: 16 GB RTX 5070: 12 GB At high resolutions or with texture packs, running out of VRAM can hurt more than a small speed gap.
Memory bus
RX 9070 XT: 256-bit RTX 5070: 192-bit Large on-chip caches can make up for a narrower bus, so bandwidth is the more telling number.

Power & Thermals
RTX 5070 leads
No contest in power & thermals: the RTX 5070 is the stronger of the two. The RTX 5070 makes its case with 54 W lower board power. The RTX 5070 draws less power, which makes it easier to cool in compact cases. The takeaway: on power & thermals, the RTX 5070 is the stronger card.
Total board power
RX 9070 XT: 304 W RTX 5070: 250 W Higher board power often comes with higher performance, so the RX 9070 XT’s appetite may be part of the price of its speed.
Recommended PSU
RX 9070 XT: 750 W RTX 5070: 650 W The recommended power supply tells you whether your current PSU can handle the card without an upgrade.

“N/A” means the manufacturer does not specify the value or we could not confirm it. Figures marked “manufacturer rating” are the maker’s own claims, not our measurements.
Price & Value
A price gap of $50 at launch won’t make or break this decision. The RX 9070 XT costs $50 more, and for that you get 4 GB more VRAM and a wider 256-bit memory bus.
These are US launch prices, recorded March 2025; what you pay today may be higher or lower.
Which One Should You Buy?
Choose the RX 9070 XT if…
- you play at high resolutions with high-quality textures (16 GB vs 12 GB VRAM)
- you push high resolutions where memory width helps (256-bit vs 192-bit bus)
- you’re loyal to AMD and happy with it
Choose the RTX 5070 if…
- you care about your power bill and a quieter case (250 W vs 304 W)
- you want to keep your current power supply (650 W vs 750 W recommended PSU)
- you want more memory bandwidth (672 GB/s vs 640 GB/s)
- you’d rather keep $50 in your pocket
