NVIDIA A40 GPU Review

The new NVIDIA A40 GPU represents an evolutionary leap in data center multi-workload performance and capabilities . The jump is made because it combines the best professional graphics in its class, adding powerful processing and AI acceleration enough to meet any current scientific, creative and design challenge that is imposed on it.

This GPU is powering the next generation of virtual workstations and server-based workloads with cutting-edge features for ray-traced rendering, simulation, virtual production, and more pro features at any time.

Provides 5 times more performance than the previous generation

The NVIDIA A40 is powered by the NVIDIA AMPERE architecture which gives it double-speed processing for single-precision floating-point (FP32) operations; It is also energy efficient to deliver significant performance improvements for graphics and simulation workflows.

Such as complex 3D computer-aided design and computer-aided engineering (CAD and CAE, respectively). It has second generation RT Cores adding to its power the new precision of Tensor Float 32 (TF32).

It provides up to 5 times the training performance compared to the previous generation model, allowing faster training of data science and AI models without requiring code changes; Tensor Cores in turn brings AI to graphics with capabilities like DLSS (Deep Learning supersampling), AI denoising, and enhanced editing for select apps.

This new GPU with its dual slot design ensures up to 2 times more energy efficiency than the previous generation ; It supports a wide range of servers from OEMs around the world.

Technical specifications of the NVIDIA A40;NVIDIA A40 GPU Review

  • GPU memory: 48 GB GDDR6 with error correction code.
  • Bandwidth: 696 GB/sec.
  • Interconnect: NVIDIA NVLink 112.5 GB/sec (bidirectional) and PCIE Gen4x16 31.5 GB/sec (bidirectional).

  • Form Factor: 4.4” (H) x 10.5” (L) Dual slot.
  • Power connector: 8-pin CPU.

More specifically its professional features come in a wide variety to encompass the AI-linked graphics market.

These functions would be:

Multi-screen support

NVIDIA Mosaic technology enables a split image to be displayed across multiple 8K monitors

New NVIDIA A40 GPU features 8K multi-monitor support , NVIDIA Mosaic multi-display technology with bezel correction, and NVIDIA Warp and Blend SDK; you also have the ability to power automatic virtual environments of massive caves (CAVE), glass walls, virtual decorators and broadcasts as well as location-based entertainment displays.

Evolution in immersive virtual reality

With the NVIDIA A40 a more immersive Virtual Reality experience would be achieved

Augmented reality and virtual reality experiences would be boosted and more immersive on head-mounted displays; The boost comes in higher resolution with accelerated graphics and higher screen bandwidth . Four-way VR SLI is the one that allows maximum performance; It does this by assigning 2 NVLink connected GPUs to each eye.

Video encoding and decoding

It has the performance you need to exploit video faster and use streaming video, security, and video serving applications . Encoders like dedicated video encoder (NVENC) and decoder engines (NVDEC) can work with multiple simultaneous streams.

Synchronization with Quadro Sync

Example of the use of Quadro Sync technology

The NVIDIA A40 GPU allows multiple displays or shields to be synchronized to create large-scale visualizations with NVIDIA Quadro Sync technology.
