5700G, X570, and PCIe 4.0 are high-performance components designed for advanced computing needs.
It's a straightforward inquiry. You're planning to assemble a PC with integrated graphics as a backup for a dedicated 3060 Ti card. I've learned the 5700G only works with PCIe 3.0, while the X570 chipset natively supports PCIe 4.0. The question is whether the X570 board can provide PCIe 4.0 support for the 3060 Ti and future GPUs, even if the CPU doesn't. Does the system require the CPU to also support PCIe 4.0 for this functionality? Alternatively, would it be better to opt for a 5800X and retain the GTX 970 as a secondary option? Ideally, using the 5700G with X570 seems best unless PCIe 4.0 isn't available in that setup.
PCIe supports backward compatibility, meaning a Gen 4 GPU fits well on any Gen 3 platform. Consider options like 10700, 10400, 11400, or 11700. These are usually more affordable and offer comparable or better performance.
The motherboard supports PCIe 4.0 only when the CPU matches that capability. Other issues with the 5700G include reduced cache size and slower clock speeds compared to the 5800X, which would negatively impact gaming performance more than the PCIe 3.0 connection. Still, I think this APU line is an upgrade over the previous generation, offering 16 lanes instead of just 8x, so bandwidth on the 3060 Ti shouldn’t be a major concern.
I understood this, but my goal is to help him take advantage of PCIe 4 for his 3060 Ti and future upgrades.
Yes, the CPU can override the PCIe version if it doesn't support it.
The processor doesn't actually possess the components needed for Gen 4, which means it can't run that version
Yes, in a straightforward way. It's not about the CPU agreeing or disagreeing, but whether it can actually run the technology. Fun fact: The X570 works with CPUs from the 2000 and 3000 series, but not with B550 or A520. For B550 and A520, only the 5700G and 5600G support PCIe 3.0.
Consider swapping the x570 for a more affordable b550 model like the b550a pro or ds3h. Think about boosting the GPU or tweaking other components in your setup. Could share some of the parts you selected for your friend’s build? I might be able to fine-tune it and maybe help with upgrades. A 5800x would work well if you get a GPU right away. PCIe Gen4 isn’t really necessary unless you’re dealing with large file transfers, like 4K videos. Most people don’t need that unless they move massive data regularly. Switching from Gen4 to Gen3 shouldn’t cause much performance loss, so it should be manageable on the GPU side.
