GeForce RTX 4090 vs GeForce RTX 5080: In-Depth Breakdown
Performance: GeForce RTX 4090 vs GeForce RTX 5080
The GeForce RTX 4090 is marginally faster, around 7% ahead of the GeForce RTX 5080. Both cards sit in the same broad class, well suited to 4K and high-refresh 1440p. The GeForce RTX 4090 packs 16,384 CUDA cores versus 10,752 on the GeForce RTX 5080.
Price & Value
The GeForce RTX 5080 currently lists from $223,477 JPY, $540,809 JPY less than the GeForce RTX 4090 at $764,286 JPY. Despite being slower, the GeForce RTX 5080 offers the better performance-per-dollar (~218% better value), so budget-focused buyers should weigh it carefully. The GeForce RTX 5080 still sits about $222,478 JPY above its $999 JPY MSRP. The GeForce RTX 4090 still sits about $762,687 JPY above its $1,599 JPY MSRP.
Power & Efficiency
At 360W against 450W, the GeForce RTX 5080 is both the lower-power and the more efficient card, making it the easier build to cool and power. Its more modern Blackwell architecture on a TSMC 4N process is part of why it does more with each watt.
VRAM & Future-Proofing
The GeForce RTX 4090 carries 24GB versus 16GB on the GeForce RTX 5080. The extra 8GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers.
Generation & Longevity
The GeForce RTX 5080 is roughly 3 years newer than the GeForce RTX 4090 (Blackwell vs Ada Lovelace), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce RTX 4090 or GeForce RTX 5080?
Choose the GeForce RTX 4090 if you want the most performance and can absorb the higher price. If you're optimizing for value, the GeForce RTX 5080 stretches your money further for only slightly lower performance.
