For any organisation looking for outstanding, no-compromise performance, then an NVIDIA Tesla-based server will meet your requirements.

What is NVIDIA Tesla?

NVIDIA’s Tesla is an enterprise-class GPGPU (General Purpose GPU), designed to handle the intense computational workloads that are typical of the scientific and industrial industries such as Deep Learning, Oil and Gas, Rendering and Material Sciences.

For the deeply parallel computations required by these and many other industries, the large number of stream processor cores in NVIDIA processors makes them highly suitable for these tasks, delivering performance that is up to 10x greater than what is possible from conventional CPU-based servers.

Whereas CPUs generally consist of several cores that can perform tasks very fast sequentially, NVIDIA’s GPU consist of thousands of smaller but more powerful cores that can execute tasks simultaneously. By way of analogy, instead of creating a picture one stroke at a time, a GPU can create the same picture in one single brush stroke.

NVIDIA Tesla GPUs power some of the world’s most powerful supercomputers, such as the Titan at Oak Ridge National Laboratory.


CUDA is a programming language based on the widely familiar C+ and is optimised to unlock the full power of the parallel architecture of NVIDIA’s Tesla GPUs.

There are now over 400 GPU-enabled applications available for CUDA in the high performance computer (HPC) space and growing, along with over 300,000 developers.

NVIDIA Tesla Applications

Computational Fluid Dynamics

CFD is the study of fluid flows. It uses numerical analysis and algorithms to solve and analyse problems associated with simulating the interaction of liquids and gases with surfaces. Using the Lattice Boltzmann method of performing fluid simulations, the original C870 Tesla processor was able to offer speedups that were several orders of magnitude greater than performance compared to CPUs in the time.

3D Rendering

In 2009, NVIDIA ported Weta’s PantaRay engine to a CUDA-based Tesla GPU to help create the lush world of Pandora for James Cameron’s ground-breaking movie Avatar, which ushered in the modern 3D movie era. The NVIDIA Tesla S1070 GPU-based server used was some 25 times faster than a conventional CPU based server.

The graph below shows the rendering performance you can expect to see in 3ds Max when rendering using the NVIDIA Iray plugin on various CPUs and GPUs. The scores are shown as relative to a single Intel Xeon E5 CPU.

High Performance Computing

More recently, benchmarks have shown NVIDIA’s Tesla K80 GPU to be two to five times faster in key HPC scientific applications, compared to an Intel Xeon Phi processor. Popular biopolymer molecular dynamics simulation packages such as AMBER, NAMD, GROMACS and LAMMPS are all optimised for NVIDIA Tesla GPUs.

Deep Learning

Deep Learning, also known as machine learning is a fast-growing field of artificial intelligence, using computers to process the huge amounts of information that is increasingly becoming available to a variety of industries. The idea is to enable computers to learn in a way that mimics how the human brain learns.

In the past three years NVIDIA’s ever advancing GPUs have made significant advances in performance in Caffe, a deep learning framework developed by the Berkeley Vision and Learning Center.

VDI Servers

Thanks to the power of the latest NVIDIA hardware many enterprises are now able to run full virtualised desktops for their users. Virtualisation brings the power of a data centre to even the thinnest of clients.

It also enables IT departments to manage desktops on a large scale from a single console interface, making upgrades and deployments much simpler.

Thanks to NVIDIA GRID technology, high-performance graphics are now available to students or engineers, architects and doctors in a fully virtualised environment.

GRID can also be used to render and stream games from the cloud, providing users with high-quality, low latency gaming. It means console quality gaming, without a console.

Maximum performance HPC: Tesla P100

For the ultimate in performance you should consider a server based on the latest generation Tesla P100 based on the Pascal architecture. The P100 is NVIDIA’s most advanced accelerator, design to work on the intense computational workloads demanded by those working on Artificial intelligence for self-driving cars or predicting our climate's future.

The P100 can deliver more than 21 teraFLOPS of FP16 performance or either 5 and 10 teraFLOPS of double and single precision performance for HPC workloads.

The P100 is the first GPU of any kind to support CoWoS (Chip-on-Wafer-on-Substrate) with HBM2 technology to deliver 3x the memory performance compared to the NVIDIA Maxwell architecture. HBM2 is ECC rated for error correction to ensure the highest levels of system accuracy and reliability.

HBM (High Bandwidth Memory) delivers higher bandwidth, than conventional GPU memory such as DDR4 or GDDR5, all while using less power in a substantially smaller form factor.

With the P100 NVIDIA has introduced an entirely new interconnect technology called NVLink. This is a point-to-point connection between a CPU and a GPU and also between a GPU and another GPU.

As the speed of GPUs increases, the PCI-E interface was becoming a bottleneck. As such, a new interconnect was required and NVLink is the solution. It enables data to move between GPUs and CPUs at five times the bandwidth of PCI Express.

NVLink-enabled Tesla P100s for servers offer a peak interconnect speed of 160GB/s, compared to 32GB/s for PCI-E.

To protect your investment in existing technologies, while still taking advantage on NVIDIA’s latest architecture the P100 is also available with a PCI-E interface. A single GPU-accelerated node powered by four Tesla P100s interconnected with PCI-E could replace up to 32 commodity CPU nodes for many HPC applications.

Using fewer powerful nodes, while performing the same or greater number of tasks, enables you to save up to 70 per cent of overall data centre costs.
