RTX 5090 D vs RTX 4090 D: which should you choose?
RTX 5090 D — NVIDIA desktop graphics card (2025, Blackwell) with 32 GB of GDDR7, averaging 183 fps at 1440p; launched at $2,299.
RTX 4090 D — NVIDIA desktop graphics card (2023, Ada Lovelace) with 24 GB of GDDR6X, averaging 137 fps at 1440p; launched at $1,599.
RTX 5090 D vs RTX 4090 D: RTX 5090 D is faster for gaming. RTX 5090 D averages 183 fps at 1440p versus 137 fps — about 34% faster. RTX 4090 D draws less power (425W vs 575W).
1080p, 1440p and 4K
At 1440p — the most common enthusiast resolution — the RTX 5090 D averages 183 fps against 137. At 4K (105 vs 78 fps) VRAM (32GB vs 24GB) and memory bandwidth matter more.
AI and creator workloads
Beyond gaming, the RTX 5090 D is quicker for AI image generation (41.9 vs 29.4 it/s in Stable Diffusion) and local LLM inference (143 vs 80 tokens/s), which increasingly matters for creators and developers.
Power and value
Board power is 575 W versus 425 W, which affects PSU headroom, case cooling and noise. At launch MSRPs of $2,299 vs $1,599, weigh the frame-rate lead against price and power draw for your target resolution.
The verdict
Both are credible choices in the graphics card comparison space; the specification table above lays out every metric so you can weigh the trade-offs that matter to you. Pick the one whose strengths line up with how you will actually use it.

Methodology
Graphics cards are compared on 3DMark Time Spy scores, average gaming frame rates at 1080p/1440p/4K, FP32 compute throughput, VRAM capacity and type, memory bandwidth, board power (TDP) and launch MSRP — plus AI workload throughput (Stable Diffusion iterations/s and local LLM tokens/s) where measured. Vintage and server GPUs without modern benchmark results are compared on specifications only, clearly labelled. Frame rates are averages across a game suite at high settings; specific titles vary.
