Shader cores
Shader cores	3,584	4,352
Boost clock
Boost clock	1,582 MHz	1,545 MHz or 1,635 MHz
Architecture
Architecture	Founders Edition specifications verified by MSI's retained technical page and datasheet; stock PNY Blower specifications verify memory bandwidth. The photo is the Founders Edition render extracted from MSI's datasheet with its original PDF transparency mask.	Main figures describe NVIDIA's reference specification; the Founders Edition has a factory overclock and higher power rating. The photo shows PNY's stock-clock 11 GB Blower, whose cooler differs from the Founders Edition geometry below. NVIDIA's original announcement named 20 September availability; its 27 September partner roundup confirms cards available by that date. The release month retains this shipment-date uncertainty.
