Cloud gaming takes the intensive processing of games from your local computer into the cloud where you can harness the power of a heavy duty server within a secure data center. With the most basic of computers or devices, as long as you have a stable and fast internet connection, you can play your favorite games online. Your hardware just needs to be able to support and sustain a constant high-definition video stream.

Some of the most common GPU-based cloud gaming services available include Microsoft’s XBox Cloud Gaming service xCloud, GeForce now, Shadow, PlayStation, Amazon Luna and Vortex. Most of these services are subscription based, although some do offer limited free access. You can find more details later in this article.

Nvidia GeForce RTX 3080 – a pearl hard to find

The NVIDIA RTX 3080 graphics card is coveted by all gamers for its superior superfast performance. Powered by their 2nd gen RTX architecture – Ampere, with streaming multiprocessors, and enhanced built-in RT and Tensor Cores, the RTX 3080 offers realistic and immersive graphics with the lowest system latency. Built for live streaming, with AI-enhanced video and voice, the RTX 3080 offers high-speed, ultra performance – every gamers’ dream.

With all these performance benefits, there is a downside. The high demand for this graphics card, along with recent manufacturing delays due to the Covid pandemic – it has led to a global shortage. This in turn has led to a massive price increase on available stock – making it unaffordable for most gamers.

If you find yourself in this situation, there is good news. This does not mean that you can not benefit from high-end software and also also enjoy AAA games.

GPU cloud gaming is your solution

GeForce NOW is the next generation in cloud gaming. With over 1000 games ready to play, GeForce Now brings the most powerful gaming supercomputer into your home. Previously known as Nvidia Grid, then Nvidia Shield, the rebranding of Geforce Now was launched in 2015.

GeForce NOW is compatible with a wide range of devices and operating systems, including Windows, Mac, SHIELD TV, iPhone and iPad and Android.

Currently GeForce NOW is only available in North America and Europe. For a premium membership, you can take advantage of the following enhanced features:

  • • higher resolutions and faster frame rates;
  • • faster access to games without having to wait for access;
  • • experience real-time ray tracing and AI and programmable shading for cinematic-quality rendering to enhance your gaming experience;
  • • extended session times.

You can choose from 2, 6 or 12 month memberships and you can also buy and redeem gift cards.

In order to use GeForce NOW, you need an internet connection with at least 15 Mbps for 720p HDTV signal format with at least 60FPS. For the best experience, latency to the NVIDIA data center should be less than 80ms but 40ms is recommended.

On a Windows machine, you need 64bit Windows 7 or newer. For Mac users, you need macOS 10.11 or higher. Your monitor needs to support at least 120Hz for 120 FPS streaming. On Android devices, you need Android 5.0 or higher with 1GB of free memory. Your phone must also support OpenGL ES2.0.

    How GPU cloud gaming server is built

    NVIDIA makes use of a high-density GPU server called the RTX Blade Server. It has 20 CPU nodes and 40 NVIDIA Turing GPUs. With a 8U rack mount configuration and Grid vGaming Software, the RTX Server can run up to 160 games concurrently. 10 twin blades provides all the power and cooling and I/O infrastructure to support the server.

    A common backplane connects the nodes to a 40Gb network module, delivering power and 10Gb Ethernet. The enclosure can support up to 10 power supply units (PSUs) with a 2200W 2N redundancy system.

    The server is configurable and can be converted into data center pods of 30 RTX servers which can serve 1000s of users concurrently. This can be further extended by deploying multiple pods in Edge Data Center locations – extending the reach to millions of users with low latency.

    The best cloud GPU gaming providers

    There are a number of cloud gaming service providers available – some from big name tech giants, but also some smaller independent companies.

    Amazon’s cloud gaming service Luna lets you play your favourite games on any device. Luna differs from other platforms as it only offers about 500 games.
