NVIDIA RTX A4500 20GB — High-End Professional GPU for Demanding Workstation Workflows

The NVIDIA RTX A4500 is a powerhouse professional graphics card engineered for designers, engineers, architects, and creators who work with the most demanding visual and compute workloads. Built on the NVIDIA Ampere architecture using Samsung's advanced 8nm process, it packs 7,168 CUDA Cores, 20GB of ECC GDDR6 memory, and 640 GB/s memory bandwidth — giving you the raw power to work interactively with the largest models, datasets, and scenes without compromise.

2X Faster Rendering with Ampere CUDA Cores

The RTX A4500 delivers 23.7 TFLOPS of single-precision (FP32) performance — up to 2X faster than the previous generation. Powered by dual FP32 data paths in the Ampere architecture, every CUDA core can now handle twice the floating-point operations per clock cycle. Whether you're running real-time 3D previews in Autodesk Maya or batch-rendering complex scenes in V-Ray or Arnold, the RTX A4500 keeps your pipeline moving at full speed.

Hardware Ray Tracing at 46.2 TFLOPS

With 56 Second-Generation RT Cores delivering 46.2 RT TFLOPS, the RTX A4500 accelerates physically accurate rendering of shadows, reflections, global illumination, ambient occlusion, and motion blur — all in real time. Working with APIs like NVIDIA OptiX, Microsoft DXR, and Vulkan Ray Tracing, the A4500 provides immediate visual feedback for complex scenes, enabling truly interactive design workflows and eliminating the wait for accurate renders.

AI-Accelerated Performance with 3rd-Gen Tensor Cores

The RTX A4500 is equipped with 224 Third-Generation Tensor Cores delivering a massive 189.2 TFLOPS of AI compute performance. This enables advanced AI-powered features inside professional applications — including AI denoising, NVIDIA DLSS upscaling, TF32 precision training, and structural sparsity — dramatically accelerating AI and data science workflows that previously required dedicated compute hardware.

20GB ECC GDDR6 — Work with the Largest Models and Datasets

The RTX A4500's 20GB of ECC GDDR6 memory with a wide 320-bit memory interface and 640 GB/s bandwidth is purpose-built for memory-intensive professional workloads. Work confidently with massive CAD assemblies, ultra-high-resolution textures, large simulation datasets, complex multi-layer compositions, and real-time 3D scenes that would overwhelm lesser GPUs. Error Correcting Code (ECC) ensures bit-perfect data integrity for mission-critical applications.

NVLink — Scale to 40GB with Dual-GPU Configuration

The RTX A4500 supports NVIDIA NVLink, allowing you to connect two RTX A4500 cards using an NVLink Bridge for a combined 40GB of unified GPU memory and up to 112.5 GB/s of bidirectional GPU-to-GPU bandwidth. This makes the A4500 ideal for memory-intensive workloads like large-scale rendering, ultra-high-resolution simulation, and complex AI model training that demand more than a single GPU can provide.

PCIe 4.0 x16 — Maximum CPU-to-GPU Bandwidth

Unlike the A400 and A1000 which use PCIe x8, the RTX A4500 leverages a full PCI Express 4.0 x16 interface — delivering twice the bandwidth of PCIe Gen 3, improving data-transfer speeds from CPU memory. This is critical for data-intensive AI, large-scale simulation, and professional visualization tasks that continuously stream large datasets between the CPU and GPU.

Next-Gen AV1 Video Decode & Hardware Encode

The RTX A4500 includes a dedicated hardware NVENC encode engine and NVDEC decode engine with full support for AV1, H.265 (HEVC), H.264, VP9, VP8, VC-1, and MPEG-2. Offload 4K and 8K video transcoding entirely from the CPU, enabling smooth real-time playback and faster exports in Adobe Premiere Pro, DaVinci Resolve, and other NLE applications — freeing CPU resources for other tasks.

Quad 5K Display Support & Quadro Sync II Compatibility

Drive up to 4 displays simultaneously at resolutions up to 5120 x 2880 @ 60Hz via 4x DisplayPort 1.4a outputs. The RTX A4500 also supports NVIDIA Quadro Sync II for frame-synchronized multi-display and multi-GPU setups — ideal for visualization walls, broadcasting environments, simulation labs, and command center deployments.

ISV-Certified for Mission-Critical Professional Applications

The NVIDIA RTX A4500 is rigorously tested and certified by leading independent software vendors (ISVs) for peak performance and reliability in the industry's most demanding professional applications, including AutoCAD, SolidWorks, CATIA, Siemens NX, PTC Creo, Ansys, Dassault Systèmes, Adobe Creative Cloud, Autodesk Maya, 3ds Max, Blender, DaVinci Resolve, Nuke, and many more.
