Performance Benchmarks

1. Gaming Performance (4K Ultra Settings)

The RTX 4090 dominates 4K gaming, often hitting 100+ FPS in demanding titles:

• Cyberpunk 2077 (RT Overdrive): ~80 FPS (DLSS 3 boosts to 120+ FPS)

• Red Dead Redemption 2: 110+ FPS

• Microsoft Flight Simulator: 90+ FPS (DLSS 3 doubles performance)

• Call of Duty: Warzone: 180+ FPS

2. Ray Tracing & DLSS 3

• DLSS 3 (Frame Generation) provides 2-3x performance boosts in supported games.

• Path Tracing (Full Ray Tracing) in Cyberpunk 2077 looks stunning but demands DLSS for smooth gameplay.

3. Content Creation & AI

• Blender, Maya, Unreal Engine 5: 50-70% faster than RTX 3090 Ti.

• Stable Diffusion AI: Generates images 3x faster than previous-gen cards.

Thermals & Power Efficiency

• Cooling: The Founders Edition stays surprisingly cool (65-75°C under load) thanks to a vapor chamber & axial fans.

• Power Draw: Peaks at 450W, requiring a high-quality PSU (ATX 3.0 recommended).

• Size: Massive 3.5-slot design—check your case clearance!

Pros & Cons

 Pros:
 Best 4K & 8K gaming performance
 DLSS 3 is a game-changer
 24GB VRAM for future-proofing
 Excellent thermals (for the power draw)

 Cons:
 Extremely expensive ($1,599+)
 Huge size—won’t fit in all cases
 Power-hungry (needs 850W+ PSU)

Verdict: Who Should Buy It?

The RTX 4090 is overkill for most gamers, but if you want:

• The absolute best 4K/8K performance

• Future-proofing for next-gen games

• AI/rendering workloads

…then it’s worth the investment. For casual gamers, an RTX 4080 or 4070 Ti may be a better value.
