By now, you probably have heard about all the buzz generated by PCIe 4.0 from the Ryzen 3000 series. If you believe all the hype, it seems like the Gen4 is the next best thing after sliced bread. \n \nSo does the PCIe Gen4 really do something to enhance your gaming experience? \n \nOn paper, the fourth generation Peripheral Component Interconnect Express performs faster compared to its predecessor. You are talking here of nearly doubling the data transfer output of the PCIe 3.0. On average, the Gen4 transfers data at a speed of 16 gigatransfers\/ps. \n \nFor instance, the X570 motherboard features the maximum of PCIe 4.0 x 16. That means the board is capable of transferring data up to 32 gigabytes per second. The maximum rate would be 64GB per second flowing in either direction, and the X570 certainly does that. The 3rd Gen, meanwhile, is capped at 16GB per second. \n \nHere’s a quick refresher on what a PCIe 4.0 is all about. \n \n \n \nBut back to the question at hand. \n \nAgain, on paper, the PCIe 4.0 will immediately boost the performance of some of the components of your PC. You can expect the graphics card, Ethernet, as well as the WiFi, to get a boost. But that’s just on paper. \n \nEven if the refresh rate is 240Hz and the resolution at 4K, you still won’t cap the PCIe 3rd Gen. There’s still a considerable difference that your graphics card has to make up before you upgrade to the 4th Gen. \n \nPCGamesN tried to answer whether the Gen4 will really result in better gaming performance. It ran benchmarks using the X570 ACE from MSI paired with the AMD Ryzen 3700X. Also included in the test are a 16GB G Skill RAM at 3,600MHz and the NVIDIA RTX 2080 Ti. \n \nFor the purposes of the test, they installed Assassin’s Creed Odyssey, Destiny 2, and Anthem. The latter is notorious for the loading screen time. \n \nThe results were quite disappointing, to say the least. \n \nThey concluded that while there’s some boost, it’s not significant enough to warrant buying a new motherboard over. The fact is that most games today are designed to run on the PCIe 3.0 standard. They can’t reach yet the listed bandwidth as advertised by the PCIe Gen4. But that’s about to change soon enough as the industry is already gearing up for the Gen5.
