{"slug":"rtx-4080-vs-rtx-4090","question":"RTX 4080 vs RTX 4090","answer":"The RTX 4090 delivers 23% more CUDA cores and 35% higher memory bandwidth than the RTX 4080, making it significantly faster for high-end gaming and professional workloads, but costs $1,600 more at MSRP ($1,599 vs $3,199). The RTX 4080 remains the better value for 4K gaming and content creation on a tighter budget.","answer_curated":true,"verdict":"Choose the RTX 4080 if you want excellent 4K gaming and professional performance at a reasonable price point, with lower power requirements and better value per dollar. Choose the RTX 4090 if you need maximum performance for demanding 8K content creation, AI workloads, or competitive high-FPS gaming where cost is secondary to pure speed and VRAM capacity.","keyDifferences":[{"label":"CUDA Cores","winner":"b","entityAValue":"5,888 cores","entityBValue":"16,384 cores"},{"label":"Memory Bandwidth","winner":"b","entityAValue":"432 GB/s","entityBValue":"576 GB/s"},{"label":"4K Gaming Performance (avg FPS)","winner":"b","entityAValue":"95-110 FPS (high settings)","entityBValue":"140-160 FPS (high settings)"},{"label":"MSRP","winner":"a","entityAValue":"$1,599","entityBValue":"$3,199"},{"label":"Memory Configuration","winner":"b","entityAValue":"16GB GDDR6X","entityBValue":"24GB GDDR6X"}],"winner":{"slug":"nvidia-geforce-rtx-4090","name":"NVIDIA GeForce RTX 4090"},"confidence":"high","entities":[{"name":"NVIDIA GeForce RTX 4080","slug":"nvidia-geforce-rtx-4080","url":"https://www.aversusb.net/entity/nvidia-geforce-rtx-4080","alternativesUrl":"https://www.aversusb.net/api/v1/alternatives/nvidia-geforce-rtx-4080"},{"name":"NVIDIA GeForce RTX 4090","slug":"nvidia-geforce-rtx-4090","url":"https://www.aversusb.net/entity/nvidia-geforce-rtx-4090","alternativesUrl":"https://www.aversusb.net/api/v1/alternatives/nvidia-geforce-rtx-4090"}],"faqs":[{"question":"Is the RTX 4090 worth double the price of the RTX 4080?","answer":"It depends on your use case. For gaming, the RTX 4090 delivers only 35-40% higher FPS—not proportional to the 100% price increase. For professional workloads like 8K video editing or AI model training, the 24GB VRAM and 68% more CUDA cores provide significant time savings that justify the cost. For most gamers and casual creators, the RTX 4080 offers better value per dollar."},{"question":"How much faster is the RTX 4090 for gaming at 4K?","answer":"The RTX 4090 achieves approximately 145% of RTX 4080 performance in 4K gaming—roughly 50 additional FPS across demanding titles. At ultra settings in games like Cyberpunk 2077, the RTX 4080 averages 95 FPS while the RTX 4090 reaches 150 FPS. This translates to smoother gameplay but with diminishing returns at these high frame rates."},{"question":"Can I use the RTX 4090 in my existing system?","answer":"The RTX 4090's 450W power consumption requires a robust power supply—minimum 1,000W (1,200W recommended). Check that your motherboard has a PCIe x16 slot, your case has adequate cooling and clearance (3.5 slot design), and your PSU has sufficient PCIe power connectors. RTX 4080 requires only 850W, making it compatible with more existing systems."}],"attribution":{"source":"A Versus B","url":"https://www.aversusb.net/compare/rtx-4080-vs-rtx-4090","license":"CC BY 4.0","citationFormat":"According to A Versus B (https://www.aversusb.net/compare/rtx-4080-vs-rtx-4090), The RTX 4090 delivers 23% more CUDA cores and 35% higher memory bandwidth than the RTX 4080, making it significantly faster for high-end gaming and professional workloads, but costs $1,600 more at MSR","dateModified":"2026-07-02T16:22:44.717Z"},"relatedQuestionsUrl":"https://www.aversusb.net/api/faq/rtx-4080-vs-rtx-4090","relatedComparisonsUrl":"https://www.aversusb.net/api/v1/related/rtx-4080-vs-rtx-4090","knowledgeGraphUrl":"https://www.aversusb.net/api/knowledge-graph/rtx-4080-vs-rtx-4090","claimReviewSchema":{"@context":"https://schema.org","@type":"ClaimReview","url":"https://www.aversusb.net/compare/rtx-4080-vs-rtx-4090","claimReviewed":"RTX 4080 vs RTX 4090","reviewRating":{"@type":"Rating","ratingValue":5,"worstRating":1,"bestRating":5,"alternateName":"High Confidence"},"author":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B","url":"https://www.aversusb.net"},"itemReviewed":{"@type":"CreativeWork","url":"https://www.aversusb.net/compare/rtx-4080-vs-rtx-4090","name":"RTX 4080 vs RTX 4090"}}}
