Gainward Phantom+ GeForce RTX 3080 Review

Gainward Phantom+ GeForce RTX 3080 is a high-end NVIDIA graphics card built on the Ampere (GA102) architecture, with 10GB of GDDR6X memory, a 1740MHz boost clock, and a 320W TDP. It is Ampere's breakout card, still a capable 1440p/4K performer years after launch.

If you're shopping for a high-end card, the Gainward Phantom+ GeForce RTX 3080 lines up against AMD's Radeon RX 6800 XT in this catalog. Expect a card around 305mm long needing a 2.5-slot opening in your case, with cuda cores count of 8704 feeding its rendering pipeline. Launch MSRP was $699, though street pricing has moved since.

Performance and Architecture

Built on NVIDIA's Ampere (GA102) architecture, the Gainward Phantom+ GeForce RTX 3080 pairs 8704 cuda cores with 10GB of GDDR6X memory on what NVIDIA rates as a 1740MHz boost clock. That combination places it in the high-end tier, where it's tuned for a specific resolution and refresh-rate target rather than being a universal do-everything card.

Power, Size, and Compatibility

At a 320W TDP, the Gainward Phantom+ GeForce RTX 3080 needs a power supply with enough headroom on the 12V rail plus whatever PCIe power connectors this variant uses. Physically it runs about 305mm long and occupies a 2.5-slot opening, so measure your case's GPU clearance and front intake fans before buying, especially in compact builds.

Comparison to Alternatives

The closest rival to the Gainward Phantom+ GeForce RTX 3080 in this catalog is AMD's Radeon RX 6800 XT, which competes at a similar price and resolution target. Shoppers who need more VRAM headroom or lower power draw than the Gainward Phantom+ GeForce RTX 3080 offers should cross-shop that card before deciding, since the two trade blows depending on the game engine and whether ray tracing or upscaling is in use.
