Are PCIe 4.0 speeds worth it?
Are PCIe 4.0 speeds worth it?
PCIe 4.0 offers only slight gains compared to PCIe 3.0, so the difference in performance may be minimal. Purchasing a X570 Mobo with a Ryzen 5 3600 might not provide significant benefits unless you're targeting specific workloads. Improvements would likely be more noticeable in gaming or resource-heavy applications rather than everyday tasks.
Typically, this question isn’t worth asking unless you’re targeting extremely high-speed SSDs or large arrays handling heavy input/output tasks. Unless you’re actively looking to gain an advantage, you likely aren’t using it.
You can save some money right away and feel more secure since your focus is on gaming, streaming, and video editing.
It seems the main point is that right now it might not be practical for most users. You could potentially boost speeds with certain SSDs or setups, but PCIe 4.0 isn’t always necessary. Graphics cards can handle faster data transfer, though high-res textures may benefit from it. APUs are constrained by PCIe lanes, and combining them with X570 boards isn’t likely to be popular unless temporary. Gaming performance usually stays solid with 8 lanes, and higher bandwidth might only matter later as technology evolves. You could compare it to past decisions about RAM upgrades.
In theory it's possible, though experiments have found minimal impact on today's systems. Still, as you mentioned, the benefits are small—around 5%—so we haven't reached full saturation even with PCIe3 x16 yet.
No GPUs with PCIe 4.0 capability are available right now, and it won't be for a long time until the next mainboard release. Most consumer and professional GPUs struggle to even reach PCIe 3.0 16x speeds. NVMs behave differently, but this is mainly about showing off rather than real benefits for regular users. Edit: reference by techpowerup. The 2080Ti can handle PCIe 3.0 8x, though not much more than the potential of a PCIe 3.0 16x interface—gains are around 2-3%, leaving a lot of bandwidth unused.
