Low-Profile RTX 4000 Ada 20GB

The PNY VCNRTX4000ADALP-PB is a workstation graphics card built on the NVIDIA Ada Lovelace architecture. It delivers 6144 CUDA cores and 20GB of GDDR6 memory across a 160-bit interface. The board measures 167 mm long and occupies a dual-slot low-profile form factor. It connects via a PCI Express 4.0 x16 slot.

Ideal for compact workstations — not

This card suits professionals who need certified drivers and 20GB VRAM in small-form-factor or dense multi-GPU chassis. The low-profile bracket fits 2U servers and slim towers where a full-height card cannot be installed. Buyers with standard ATX cases and full-height brackets gain no advantage from the reduced bracket height. Workloads requiring more than 20GB of frame buffer should consider higher-capacity alternatives.

20GB GDDR6 on a 160-bit bus

The 20GB memory capacity paired with a 160-bit interface determines the maximum dataset size and bandwidth available for rendering, simulation and AI inference. This specification is the primary factor in deciding whether the card meets a given professional workload.

Questions about this item

Will the dual-slot low-profile cooler need any periodic cleaning or thermal-pad replacement?

The card uses a dual-slot low-profile cooler with 167 mm length; dust buildup on the heatsink fins is the main maintenance item, and thermal pads are not user-serviceable.

Which limit appears first during long render jobs — the 160-bit memory bus or the 20 GB GDDR6 capacity?

The 160-bit bus delivers lower bandwidth than wider workstation cards, so memory throughput typically saturates before the 20 GB frame buffer fills.

How much heat and noise should I expect when the GPU runs at 19.2 TFLOPS FP32 all day?

Sustained 19.2 TFLOPS FP32 load will push the dual-slot cooler to its thermal limit, producing noticeable fan noise and case heat in a low-profile chassis.
