RTX 5070 vs 4090: Truth Behind Nvidia's DLSS 4 Performance Claims

How DLSS Frame Generation Creates Misleading Performance Metrics

Recent Nvidia presentations claim the RTX 5070 matches the 4090's performance. This comparison relies entirely on DLSS 4's Multiframe Generation technology, not raw rendering power. Traditional DLSS 3 Frame Generation inserts one AI-created frame between each rendered frame, effectively doubling frame rates. For example, 60 rendered FPS becomes 120 perceived FPS. However, input latency remains locked at the original 60 FPS responsiveness level.

DLSS 4's revolutionary Multiframe Generation takes this further by inserting three AI frames per rendered frame. This quadruples perceived output: 60 rendered FPS transforms into 240 displayed FPS. The crucial tradeoff remains unchanged: visual smoothness improves dramatically, but input latency still corresponds to the base rendering rate. Your game will look like 240 FPS but feel like 60 FPS.

Decoding Nvidia's Marketing Claims

The Frame Generation Mathematics Behind "5070 = 4090"

Nvidia's claim hinges on this calculation: A 4090 rendering 60 FPS with DLSS 3 outputs 120 FPS. A 5070 rendering just 30 FPS with DLSS 4 Multiframe Generation (4X mode) also outputs 120 FPS. This creates the illusion of parity while masking the 5070's significantly lower raw rendering performance. Performance charts prominently featuring Cyberpunk 2077 and Alan Wake 2 exploit this DLSS 4 advantage, while omitting titles without frame generation support.

Far Cry 6: The Revelatory Benchmark

Nvidia's own Far Cry 6 comparison provides critical context. Without DLSS manipulation, the charts reveal the 5070 delivers approximately 25% higher performance than the 4070, not 4090-level results. This confirms that frame generation technology artificially inflates the headline numbers in supported titles. Industry analysts universally regard non-DLSS benchmarks as more accurate reflections of true rendering capability.

Practical Implications for Gamers

Latency vs. Visuals: The Eternal Tradeoff

Frame generation technologies prioritize visual fluidity over responsiveness. Competitive gamers should note this critical distinction:

• DLSS 3 (2X): Rendered FPS × 2 = Displayed FPS
• DLSS 4 (4X): Rendered FPS × 4 = Displayed FPS
  Both maintain latency at the original rendered FPS level. For optimal results, always ensure your base frame rate exceeds 60 FPS before enabling frame generation to avoid sluggish controls.

Navigating Marketing Claims

Three essential verification steps when evaluating GPU performance claims:

1. Identify whether DLSS frame generation is enabled in benchmarks
2. Check for non-DLSS comparisons like Far Cry 6 results
3. Note the rendered FPS, not just displayed FPS figures
   Third-party reviewers like TechPowerUp and Gamers Nexus typically provide these critical distinctions.

Reality-Check Action Guide

Apply these immediately when assessing GPU upgrades:

1. Cross-reference DLSS and non-DLSS benchmarks
2. Prioritize latency-sensitive titles (esports) when testing
3. Monitor actual rendered FPS using tools like CapFrameX
4. Demand transparency about frame generation usage
5. Consider your display's refresh rate limitations

Recommended analysis tools:

• MSI Afterburner (for real-time rendered FPS monitoring)
• NVIDIA FrameView (latency measurement toolkit)
• Blur Busters UFO Test (motion clarity verification)

The Verdict on DLSS 4 Performance Claims

Nvidia's RTX 5070 equals 4090 performance only when leveraging DLSS 4's Multiframe Generation in specific titles. Raw rendering performance sits closer to 25% above the 4070, as proven by non-DLSS benchmarks. While frame generation delivers smoother visuals, it cannot overcome the fundamental latency limitations of the base rendered frame rate.
