NVIDIA RTX A4500 20G GDDR6 ECC graphics card

SKU CH-R1W4-RC72R

Professional GPU with 7168 CUDA cores, 20GB GDDR6 ECC memory, 56 RT Cores and 224 Tensor Cores for modelling, rendering and AI workloads

  • Chipset makerNVIDIA
  • 7168 CUDA cores deliver 23.7 TFLOPS for fast modelling and rendering
  • 20 GB GDDR6 with ECC on a 320-bit bus gives 696 GB/s bandwidth for large datasets
  • 56 RT cores provide cinematic-quality lighting and shadows
  • 224 Tensor cores supply 189.2 TFLOPS AI compute for accelerated post-production
  • Four DisplayPort 1.4 outputs drive multi-display 4K and 8K workflows

Professional 20 GB GPU for creative workloads

The NVIDIA RTX A4500 20G delivers 20 GB of GDDR6 ECC memory on a 320-bit bus with 696 GB/s bandwidth. Ampere architecture provides 7168 CUDA cores and 23.7 TFLOPS single-precision performance. It connects through PCI Express 4.0 x16 and drives up to four displays via DP 1.4.

Suited for modelling, rendering

Professionals handling large datasets benefit from ECC error correction and 189.2 TFLOPS AI compute via 224 Tensor cores. 56 RT cores accelerate realistic lighting workflows. Users focused on gaming or entry-level tasks should consider alternatives aligned with those needs.

Handles complex scenes

The 20 GB frame buffer comfortably accommodates high-resolution textures, large assemblies and multi-layer timelines. Memory capacity becomes the limit when scenes exceed the available VRAM, requiring out-of-core techniques or a card with greater memory.

Questions about this item

What motherboard slot is required for the RTX A4500 20G to run at PCI Express 4.0 x16?

The card needs a PCIe 4.0 x16 slot on the motherboard; it will also operate in a PCIe 3.0 x16 slot at reduced bandwidth.

Can I keep my existing DisplayPort 1.2 monitors when using the A4500's four DP 1.4 outputs?

Yes, the four DisplayPort 1.4 connectors are backward compatible with DP 1.2 displays, though 8K output requires DP 1.4 cables and monitors.

How can I verify the 20 GB GDDR6 ECC memory is active after installation?

In NVIDIA Control Panel or GPU-Z the memory size will show 20 GB with ECC enabled, and driver logs will confirm ECC operation.
