NVIDIA's Ada Lovelace-generation flagship graphics card with 24 GB of GDDR6X memory on a 384-bit interface.
Works with
- PCI Express Gen 4 x16 slot (backward compatible with Gen 3)
- 850 W power supply with a 450 W-or-greater PCIe Gen 5 cable or three PCIe 8-pin connectors
- A chassis that clears a 304 mm, 3-slot (61 mm) card
Is it for you?
NVIDIA's Ada Lovelace-generation flagship graphics card with 24 GB of GDDR6X memory on a 384-bit interface, 16384 CUDA cores and a 450 W total graphics power target, in the triple-slot Founders Edition dual axial flow-through cooler.
Choose it if these matter
- 24 GB of GDDR6X memory still loads most mid-size local language models comfortably
- 16384 CUDA cores with 1321 AI TOPS of tensor throughput, well ahead of non-flagship current cards
- Deeply available on the secondhand market after three years of production, often well below its launch cost
Skip it if these rule it out
- 450 W total graphics power and an 850 W recommended power supply, plus a 3-slot, 61 mm thick card that needs a roomy case
- NVIDIA's own product page links no Amazon listing for the Founders Edition, only its own store's buying options, so finding one means searching for the exact model
- PCIe Gen 4 rather than Gen 5, and roughly a quarter of the RTX 5090's memory bandwidth for large-model inference

- What differs
- NVIDIA's own Founders Edition of the flagship card, the reference dual flow-through design.
- Best for
- Local AI inference and gaming on a single flagship card.
Watch out
- Partner cards (ASUS, MSI, Gigabyte and others) are different physical cards with the same GPU; only the Founders Edition is NVIDIA's own design.
- Laptop GPUs carry similar RTX 5090/4090 names but are soldered, lower-power parts, not this desktop card.
