RTX 5070 vs RTX 4070 Super: Which GPU Wins?

The RTX 5070 is the better graphics card for gaming, offering roughly 20% more raw performance than the RTX 4070 Super, plus newer DLSS 4 features. However, the RTX 4070 Super remains a strong value if you can find it at a lower price, especially for 1440p gaming without ray tracing at maximum settings.

Background: The 50-Series Arrives

NVIDIA launched the RTX 50-series (Blackwell) in early 2025, starting with the RTX 5080 and 5090, then the RTX 5070 Ti and RTX 5070 in March. The RTX 5070 replaces the RTX 4070 Super in the lineup, targeting the same sweet spot: high-refresh 1440p gaming and entry-level 4K. Both cards use the same 12GB GDDR7 (5070) or GDDR6X (4070 Super) memory configuration, but the newer architecture brings significant improvements in ray tracing, AI upscaling, and power efficiency.

How They Compare: Specs and Performance

Here’s a quick look at the key specifications:

• RTX 5070: 6,144 CUDA cores, 12GB GDDR7, 192-bit bus, 250W TGP, PCIe 5.0
• RTX 4070 Super: 7,168 CUDA cores, 12GB GDDR6X, 192-bit bus, 220W TGP, PCIe 4.0

Despite having fewer CUDA cores, the RTX 5070’s Blackwell architecture delivers higher instructions per clock and faster memory. In gaming benchmarks, the 5070 is about 15-20% faster at 1440p and 4K, depending on the title. For example, in Cyberpunk 2077 with ray tracing, the 5070 can push over 100 fps with DLSS 4, while the 4070 Super sits around 80 fps with DLSS 3.

DLSS 4 and Multi-Frame Generation

The biggest feature gap is DLSS 4, exclusive to RTX 50-series cards. DLSS 4 introduces Multi-Frame Generation, which uses AI to generate up to three extra frames for every rendered frame. This can triple or quadruple frame rates in supported games. The RTX 4070 Super only supports DLSS 3, which generates a single extra frame. In practice, DLSS 4 makes the 5070 feel dramatically smoother in titles like Alan Wake 2, Black Myth: Wukong, and Star Wars Outlaws. Not every game supports it yet, but the list is growing.

Power Consumption and Thermals

The RTX 5070 has a higher TGP (250W vs 220W), but it’s more efficient per frame. In gaming, the 5070 typically draws about 220-240W, while the 4070 Super uses around 200W. Both cards run cool with dual-fan designs, and the 5070’s new architecture runs quieter under load. If you have a 650W PSU, both work, but NVIDIA recommends 650W for the 5070 and 600W for the 4070 Super. Always check your PSU’s PCIe power connectors—the 5070 uses a 12V-2×6 connector, which may require an adapter if your PSU is older.

How to Choose: Which Should You Buy?

Your choice depends on your monitor, budget, and upgrade cycle:

• If you play at 1440p with a 144Hz+ monitor: The RTX 5070 is worth the extra cost if you want to max out settings and enable ray tracing. The DLSS 4 frame generation ensures future-proofing.
• If you play at 1080p or 1440p at 60Hz: The RTX 4070 Super is more than enough and will save you money. It still handles most games at high settings without breaking a sweat.
• If you plan to keep the card for 4+ years: The 5070’s newer features and higher performance make it a better long-term investment.
• If you’re on a strict budget: Look for a discounted 4070 Super—it’s still a fantastic card for 1440p and can be found for significantly less than the 5070’s launch price.

Also consider your CPU. At 1080p, a weaker CPU may bottleneck the 5070, so pair it with a modern mid-range or high-end processor like a Ryzen 5 7600 or Core i5-13600K.

Common Problems and Misconceptions

One common misconception is that more CUDA cores always mean better performance—the 5070 disproves that with fewer cores but higher efficiency. Another issue: some users worry about the 12GB VRAM being insufficient for future games. While 12GB is still fine for 1440p, 4K textures in some titles (like Hogwarts Legacy) can push close to that limit. For 4K gaming, both cards are entry-level; if you want headroom, consider the RTX 5070 Ti or 5080.

Power connector issues: the 12V-2×6 connector on the 5070 has been known to melt if not seated properly. Ensure the connector clicks in firmly and do not bend the cable sharply near the connector. This is rare, but worth noting.

Cost and Value

At launch, the RTX 5070 has an MSRP of $549, while the RTX 4070 Super launched at $599 but has dropped to around $450-500 in stores. If you can get the 4070 Super for $100+ less, it offers better price-to-performance for 1440p gaming without ray tracing. However, if you value DLSS 4 and want the latest tech, the 5070’s 20% performance boost and future-proofing justify the higher price for many gamers.

Frequently Asked Questions

Is the RTX 5070 worth the extra $100 over the 4070 Super?

Yes, for most gamers, the 5070 is worth it because you get ~20% more performance, DLSS 4, and better ray tracing. If you’re on a tight budget and don’t care about the latest features, the 4070 Super is still a great deal.

Can the RTX 4070 Super handle 4K gaming?

Yes, but with compromises. You’ll need to lower settings to high (not ultra) and use DLSS Quality mode to get 60 fps in most AAA titles. The RTX 5070 does it a bit more comfortably, but both are better suited for 1440p.

Does the RTX 5070 work with older motherboards?

Yes, the RTX 5070 uses PCIe 5.0 but is backward compatible with PCIe 4.0 and 3.0 slots. You may lose a tiny bit of performance (1-3%) on PCIe 3.0, but it will work fine.

How much VRAM do I need for future games?

12GB is currently the sweet spot for 1440p. For 4K, 16GB is safer, but 12GB will still work if you’re willing to adjust texture quality. Both cards have 12GB, so this isn’t a differentiator.

Is DLSS 4 really that much better than DLSS 3?

Yes, Multi-Frame Generation can triple frame rates, making games feel much smoother. It also improves image quality and reduces ghosting. However, it only works on RTX 50-series cards, so the 4070 Super can’t use it.

Should I wait for the RTX 5060 Ti instead?

If you’re on a budget, waiting for the RTX 5060 Ti (expected later in 2025) might be wise. It will likely offer similar performance to the 4070 Super but at a lower price, with DLSS 4. But if you need a card now, the 5070 is a solid choice.
