When the gamers are upgrading their gaming PC they usually gets confused in the debate of NVIDIA GeForce RTX 4070 vs 3080. This is because both the GPU provides amazing and fast performance but they are different from each other because of their architecture, power efficiency and price to performance ratio.
In 2025, NVIDIA is massively dominating the GPU market and acquired almost 92% market share. In accordance to Jon Peddie research, AMD market share has fall up to 8%. On the other hand, Intel GPUs have been unavailable in the market.
- NVIDIA’s RTX 50 series has initiated move this dominance. It has overshadowed AMD’s new RDNA 4 launch and Intel Battlemage Arc GPUs. Intel Arc GPU has faced lot of difficulties with its availability and demand.
- It is expected that GPU market shrink gradually in coming few years. Due to this NVIDIA is dominating the field of gaming and Ai by keeping large installed base.
- This blog not just focus on selecting between RTX 4070 and 3080 but also it focuses on NVIDIA’s current architectural generation. Ada Lovelace (4070) and Ampere (3080).
