NVIDIA RTX A4000 16G Single-slot Professional graphics card

SKU CH-7ATS-V1PJA

Single-slot professional GPU with 16 GB GDDR6 ECC memory, 6144 CUDA cores, 192 Tensor cores and 48 RT cores delivering 19.2 TFLOPS single-precision performance

  • Chipset ManufacturerNVIDIA
  • Ampere architecture enables real-time ray tracing for realistic visuals
  • 6144 CUDA cores deliver 19.2 TFLOPS single-precision compute power
  • 192 third-gen Tensor cores provide 153.4 TFLOPS AI acceleration
  • 16 GB GDDR6 with ECC on 256-bit bus gives 448 GB/s bandwidth
  • Four DisplayPort 1.4a outputs drive up to four 4K displays at 120 Hz

Single-slot professional GPU

The NVIDIA RTX A4000 16G fits a full Ampere architecture into a 112mm × 241mm single-slot card. It delivers 6144 CUDA cores, 192 third-generation Tensor cores and 48 second-generation RT cores. Base clock runs at 735 MHz with a 1560 MHz boost, producing 19.2 TFLOPS single-precision and 37.4 TFLOPS ray-tracing throughput.

16 GB GDDR6 with ECC

Memory operates at 1750 MHz across a 256-bit bus for 448 GB/s bandwidth. ECC protection guards against data corruption in long renders or simulation runs. Four DisplayPort 1.4a outputs drive up to four 4096×2160 panels at 120 Hz, four 5120×2880 panels at 60 Hz or two 7680×4320 panels at 60 Hz.

Workstation builders needing density

The single-slot profile suits multi-GPU render nodes, compact workstations and rackmount chassis where double-width cards cannot fit. Applications relying on vGPU virtualization should select a different model because vGPU support is absent. Users requiring more than 16 GB frame buffer must move to a higher-capacity board.

Questions about this item

Will the 16 GB GDDR6 ECC memory or the GA104 GPU require scheduled replacement?

The 16 GB GDDR6 memory and GA104 GPU are soldered to the board and have no user-serviceable replacement schedule under normal operation.

Does the 448 GB/s memory bandwidth or the 19.2 TFLOPS compute ceiling limit sustained workloads first?

The 19.2 TFLOPS single-precision ceiling is reached before the 448 GB/s bandwidth saturates in typical professional rendering tasks.

How much heat does the single-slot design dissipate when the 6144 CUDA cores run at 1560 MHz boost all day?

The single-slot cooler exhausts heat through the rear bracket; sustained boost clocks are maintained within the card's thermal design limits.
