Verdict

The Gainward GeForce RTX 4090 Phantom is a high-performance graphics card built on NVIDIA's Ada Lovelace architecture, featuring 16,384 CUDA cores and 24GB of GDDR6X memory with a 384-bit bus and 1,008 GB/s bandwidth. It operates at a base clock of 2,235 MHz and a boost clock of 2,520 MHz, supported by a 450W TGP and a triple-fan 'Cyclone Fan' cooling system that occupies a substantial 3.5-slot profile. Key pros include exceptional 4K and 8K gaming performance, advanced DLSS 3 support, and a dual BIOS feature that allows users to toggle between performance and silent modes. However, main cons include its massive physical size that may not fit in many cases, a very high power requirement typically necessitating a 1,000W PSU, and its significant retail price.
