Architecture
Architecture	GP104; 7.2 billion transistors; 160 texture units and 64 ROPs. Main specifications and photo describe the original Founders Edition; the later 11 Gbps memory version is represented by MSI's GAMING+ 8G in its default Gaming mode.	Reference main figures follow NVIDIA's retained 900-series table. Photo shows MSI's reference-style GTX 980 Ti 6GD5. The first-sale date comes from TweakTown's contemporary coverage, which explicitly states announced and released June 1; the original maker launch page is retired.
