3. Gaming Performance: Rasterization (Traditional Rendering)

Rasterization remains the bedrock of GPU performance evaluation. This section analyzes performance using average frames per second (FPS) across various resolutions with high or ultra settings.

1440p (WQHD) Performance: The Sweet Spot

This is the primary target resolution for both cards.

• Performance: Extremely close. Aggregated data suggests the RTX 4070 Super holds a slight edge (approx. 5% to 10% higher FPS on average).
• Variability: The gap is often marginal, and AMD-optimized titles (e.g., Starfield) can see the RX 7800 XT match or slightly exceed the 4070 Super.
• Key Takeaway: Near-parity in performance despite the 4070 Super’s higher specs and price highlights RDNA 3’s efficiency in rasterization.

4K Performance: Pushing the Limits

Both cards are capable of playable 4K (often 60+ FPS), but may require setting adjustments or upscaling in demanding titles.

• Performance Delta: Generally mirrors the 1440p trend, with the RTX 4070 Super often maintaining a slight lead or achieving parity.
• VRAM Impact: While the RX 7800 XT’s 16GB VRAM is theoretically advantageous, benchmarks don’t consistently show it overcoming the 4070 Super’s 12GB card in current games. This suggests 12GB is often sufficient, or the 4070 Super’s architecture compensates. However, 16GB offers potential headroom for future titles or mods.

1080p (Full HD) Performance: High Refresh Rate Focus

Performance can become CPU-bound, masking GPU differences. Relevant for ultra-high refresh rate monitors (240Hz+).

• Performance Trend: The gap often narrows further, with the RX 7800 XT frequently matching or surpassing the 4070 Super more often than at 1440p.

Rasterization Summary

In pure rasterization, the RX 7800 XT and RTX 4070 Super are exceptionally close competitors. The RTX 4070 Super averages a small lead (5-10%), but this is often negligible and game-dependent. Given the significant price difference ($100+), the RX 7800 XT offers superior rasterization cost-per-frame value.

4. Gaming Performance: Ray Tracing (Enhanced Realism)

Ray tracing (RT) simulates light more accurately for realistic visuals but is computationally very demanding.

Performance Difference: NVIDIA’s Stronghold

NVIDIA’s RTX series traditionally excels in ray tracing due to mature, efficient RT cores.

• Advantage: The RTX 4070 Super significantly outperforms the RX 7800 XT when ray tracing is enabled.
• FPS Gap: Averages range from 15% to over 50% higher FPS for the 4070 Super, depending on the game and RT intensity. The difference is particularly stark in demanding titles like Cyberpunk 2077 (RT Overdrive).

Playability and Experience

• RX 7800 XT: Can run RT effects, but performance often drops significantly at 1440p+, frequently requiring compromises (lower RT quality, aggressive FSR) for smooth gameplay.
• RTX 4070 Super: Maintains higher frame rates, making demanding RT settings more viable. This advantage is amplified by DLSS, especially DLSS 3 Frame Generation, enabling high-fidelity RT experiences often unattainable on the RX 7800 XT. The difference often translates to better playability at desired settings.

Architectural Notes and VRAM

Despite the RX 7800 XT having more Ray Accelerators (60 vs. 56 RT Cores), NVIDIA’s 3rd-gen RT Cores are far more efficient per unit. The primary bottleneck for the RX 7800 XT in heavy RT is raw ray processing capability, not its 16GB VRAM.

Ray Tracing Summary

For users prioritizing realistic lighting and intending to use ray tracing extensively, the GeForce RTX 4070 Super holds a clear and substantial advantage. Its superior RT performance, combined with DLSS, provides a significantly better ray-traced gaming experience, justifying its higher price for RT enthusiasts.

5. Upscaling and Frame Generation: Boosting Performance

These technologies are crucial for mitigating the performance impact of high resolutions and ray tracing.

Technology Overview

• Upscaling (Boosting FPS via Lower Render Resolution):
  • AMD FSR (FidelityFX Super Resolution): Open-source, wide compatibility. FSR 1 (Spatial), FSR 2/3 (Temporal), FSR 4 (AI/ML-based, currently RX 9000+ exclusive).
  • NVIDIA DLSS (Deep Learning Super Sampling): Proprietary, requires RTX GPUs (Tensor Cores). DLSS 2 (Super Resolution), DLSS 3 (+Frame Generation), DLSS 3.5 (+Ray Reconstruction).
• Frame Generation (FG – Inserting AI Frames for Smoothness):
  • AMD FSR 3 FG: Game integration needed. Compatible with RX 5700+ and NVIDIA GPUs.
  • AMD AFMF (Fluid Motion Frames): Driver-level, broad DX11/12 compatibility (RX 6000+), no game integration needed, but potential UI issues/latency.
  • NVIDIA DLSS 3 FG: Game integration needed. Exclusive to RTX 40 series+.

Performance Uplift

Both upscaling methods offer significant FPS boosts depending on the quality mode. Frame Generation can dramatically increase displayed FPS (often nearly doubling), but introduces latency.

Image Quality Comparison

• Upscaling: DLSS 2/3/3.5 is generally considered superior to FSR 2/3.1, offering sharper details and fewer artifacts due to its AI foundation. However, early FSR 4 previews show significant quality improvements, potentially closing the gap.
• Frame Generation: Both FSR 3 FG and DLSS 3 FG can exhibit artifacts in fast motion or around UI elements. AFMF is known for potential UI distortions.

Latency Considerations

Frame generation adds input latency.

• NVIDIA Reflex: Tightly integrated with DLSS 3 FG, highly effective at mitigating latency (ideal base FPS 60+).
• AMD Anti-Lag / Anti-Lag 2: Anti-Lag+ was withdrawn. Anti-Lag 2 requires game integration and has very limited support currently (CS2, Dota 2, GoT).
• Overall Latency: While FSR 3 FG might have slightly lower raw latency penalty, Reflex often results in lower perceived latency for DLSS 3 FG. AFMF generally adds the most latency.

Game Support and Ecosystem

• DLSS 2/3: Enjoys wider adoption in AAA titles currently. Ecosystem is cohesive but proprietary.
• FSR 2/3: Adoption is growing, benefits from open-source nature. FSR 3.1 modularity may help adoption.
• AFMF: Broad compatibility is a major plus, but driver-level limitations exist.
• FSR 4: Promising quality leap, but initial hardware exclusivity (RX 9000+) limits immediate impact for RX 7800 XT.
