NVIDIA RTX 4000 Ada
$1100$1250 MSRP
The NVIDIA RTX 4000 Ada is a single-slot professional GPU with 20GB of GDDR6 memory. Its compact form factor and low 130W TDP make it ideal for dense workstation builds and inference servers. The 20GB VRAM handles 14B-22B models comfortably. It is popular in AI inference deployment where power efficiency and rack density matter more than raw throughput.
Best ForLow-power AI inference servers and compact workstations
VerdictUnique single-slot form factor with solid VRAM — niche but valuable for the right use case.
