Ryzen 5900X CPU ReviewJanuary 3, 2021
There are a number of benefits to the Ryzen 5900X CPU. The 5000 series line up is a culmination of AMD battling it out with Intel over the years. With 1st, 2nd and 3rd gen processors (Ryzen 1000, 2000 and 3000 lineups), Ryzen had better multi-core processing then Intel. So if you are multitasking (but not gaming), Ryzen was the winner. Meanwhile, Intel had better single core performance, so they’d come out on top when playing video games.
That’s changed now with the 5900X chip. Something that many are talking about as well is Intel’s outright dismissal of PCIe 4.0. The newest PCI express standard means that 4.0 operates at twice the bandwidth capacity of 3.0. The newest PCI express 4.0 allows for bandwidth to flow at 32 GB/s in each direction, while 3.0 allows for only 16 Gigabytes per second.
One major and interesting fact is that this CPU kind of stands in a realm of its own. The Intel Core i9 10900K was released to attack the Ryzen 9 3900X, but it didn’t do a very good job of it. The Ryzen 9 5900X chip totally destroys the Core i9 10900k.
Another cool thing worth mentioning about the new Ryzen 5000 series lineup of CPUs, is that you don’t need to buy a new mainboard in many respects in order to upgrade. If your motherboard is Ryzen 5000 series compatible, you just need to download and flash your BIOS with a BIOS upgrade to make it work.
I bought a Ryzen 5900 and my computer won’t boot. Why is this happening? Should I return my Ryzen 5900 chip?
For many people who buy a Ryzen 5000 series motherboard, the CPU won’t work right out of the box. In order to make it work, you need to install a compatible CPU first – like a 2000 or 3000 series CPU (like a 3600) and then do the BIOS upgrade for the motherboard to be able to talk to the 5000 series chip. Therefore, buying a Ryzen 3600 or other first and then upgrading to the 5900 chip is a good way to go. If you don’t have a Ryzen chip of a previous generation, you’ll have some trouble because you won’t be able to use your 5900 chip until you downgrade, upgrade BIOS, and then upgrade your chip.
Buying a chip in order to do the upgrade can be an expensive solution. One thing you could look at doing is talk to a local computer shop, ask them to upgrade the BIOS for you. You may pay a fee to do this, but if you compare it against the cost of having to buy two CPUs, especially just to have one sit and do nothing – then the cost of having the repair shop do this work for you is likely a lot less. You also can’t return a CPU after you’ve put thermal paste on it and mounted it to your mainboard, in order to conduct the upgrade process.
