Nvidia RTX 4090: A powerhouse with a few snags
Sure, the RTX 4090 has impressive specs—lots of CUDA cores, awesome memory bandwidth, and a price that's more wallet-friendly than the pro options. Of course, it is understood that companies see it as a smart choice for AI calculations at home.
Temptation: More cards, better?
It might feel obvious to tuck in several RTX 4090 cards to get extra cream in the AI jobs. The idea is simple: the more powerful graphics cards, the better the performance, right?
The pitfalls of multiple GPUs
1. No NVLink: Seg communication
Unlike the RTX A6000, the RTX 4090 lacks support for NVLink, the fast link that lets graphics cards talk efficiently with each other. Without NVLink, cards are forced to use the slower PCIe interface, which can create bottlenecks when collaborating on heavy AI tasks.
2. Power and heat: Be sure to think about the cold before it's too late
A single RTX 4090 can draw up to 450 watts when it's working hard. If you insert several of these, you will need not only a solid power supply unit, but also smart cooling systems. Otherwise, you run the risk of overheating, throttling performance or even the stuff breaking.
3. Space shortage: Crowded worse
These graphics cards are no little rascals. Fitting multiple RTX 4090s into one chassis requires careful planning to ensure good airflow and that everything fits on the motherboard. If it becomes too crowded, the risk of heat problems and premature wear of the components increases.
Why you should hire professionals like Compliq
Tailor-made solutions
We at Compliq know how to put together a system that is optimized for your specific needs. We have been doing this for 30 years and are certified in handling unique computer builds. We ensure everything from compatibility between components to how to build a balanced and, above all, reliable computer.
Maximized performance and durability
With experts at the helm, you get a machine where power supply, cooling and everything else is thought out and well built. That means not only better performance in the here and now, but also that the stuff lasts longer.
Access to better stuff
We as professional computer builders often have access to components and tools that can be difficult to find at regular traders. It happens that sometimes we have to 3d print solutions to be able to install hardware and you can't get that over the counter. We can also advise you on alternative solutions that give you more bang for your buck and suit your AI projects better.
Is it worth the money? Oh, absolutely!
When you're already saving up on an RTX A6000 card, it's not a good idea to even save on the build itself. The time it takes to build especially with the lack of space that can occur when two really large boards are to be installed with adequate cooling. It is therefore important to consider the costs of troubleshooting, downtime and the risk of broken stuff. We can help you avoid these pitfalls and make sure your investment really pays off.
Make the right choice for your AI venture
Before you embark on a complicated build with multiple RTX 4090 cards, consider what we at Compliq can contribute:
Needs analysis: They can assess whether a multi-GPU solution is really best for your project.
The right components: Professionals can recommend hardware that provides better performance per dime, maybe even suggest pro cards or other setups.
Future-proof: An expertly built PC is often easier to upgrade and lasts longer, saving money in the long run.
Compliq has an agreement with leading universities in Sweden to build powerful computers
Building a powerful AI computer is more than just screwing a few parts together. It requires knowledge of everything from how components work together to how to get maximum performance over time. Lock us building so you can focus on innovation.
