The 'gold standard' reference design from NVIDIA, featuring a unique dual-axial flow-through cooling design and a compact, premium aesthetic.

Includes 24 GB of GDDR6X memory on a 384-bit bus with 1008 GB/s of memory bandwidth.
Features 16,384 CUDA cores, 3rd-generation ray tracing cores, 4th-generation Tensor cores, and a boost clock up to 2.52 GHz.
Uses NVIDIA’s dual-axial flow-through cooling design in a 304 mm-long, 3-slot card.
The NVIDIA GeForce RTX 4090 Founders Edition is an Ada Lovelace GPU with 24 GB of GDDR6X memory, a 2.52 GHz boost clock, PCIe 4.0 x16 connectivity, and a 3-slot dual-axial flow-through reference design.
The review describes the RTX 4090 Founders Edition as an immensely powerful debut of the Ada Lovelace architecture, capable of extreme 4K gaming performance, though it notes the card is expensive and physically enormous.
The review highlights the card's flagship performance, noting its 76.3 billion transistors and 16,384 CUDA cores.
The review calls the RTX 4090 brutally fast, praising its ray tracing performance and cooling design, while acknowledging its very high price, power draw, and massive physical size.
The reviewer praises the card's performance for 4K 120FPS gaming and describes the DLSS 3 technology as impressive, recommending it as a top choice for ultra-enthusiasts despite its large size.
