Question Ryzen 7 5700g gen 4.0 vs 3.0

[Yupperzzzzz]

People seem to say a 5700g is not pcie gen 4 compatable. Well what does that mean? A gen 4 nvme would be handicapped in terms of speed or that your gen 4 gpu slot would be handicapped in terms of speed?

from what I can tell, its both GPU & Nvme that are restricted to PCIe3.0

Designed to be an SoC in its own right, Cezanne combines an 8-core CPU based on the Zen 3 microarchitecture with an iGPU based on Vega, along with a dual-channel DDR4 integrated memory controller, and I/O based on PCI-Express Gen 3

AMD Ryzen 7 5700G Review - Great Performance & Integrated Graphics

With the Ryzen 7 5700G, AMD is finally bringing their most powerful APU to the retail DIY channel. With 512 graphics cores based on the Vega architecture, the IGP is over twice as fast as Intel's Rocket Lake graphics. Thanks to the Zen 3 architecture, the eight CPU cores are blazing fast, too.

See connectivity, yes 5700g is limited to pcie 3.

That doesn't really mean much for a graphics card since pcie 3 bandwidth is hardly taxed even by the fastest cards at 16x. M2 is different since ssds operate at 4x so transfer rates are halved. Still, random access times which is associated with game load performance, asset streaming and all that jazz is the same vs pcie 4 ssd speeds and also comparable to sata type ssds mind you. You'll not notice a difference.

The only difference or advantage pcie 4 ssds have, besides quicker transfer speeds (as in copying large files to one place to another be quicker) is the prospect of direct storage technology that Microsoft is working on. Where by, larger amounts of data can be loaded into ram then to graphics card vram much sooner. That is once games are designed to use DS more often and effectively, should help performance in large open world games for example with fair bit of detail.

the noticeable difference between pci 3 & 4 nvme is tiny unless you use really big files. The faster they get the less you gain back. PCIe 3 is fast enough really. All faster seems to achieve is more heat.

7 5700x gen 4.0 compat all around?

Yes

Its just the APU that are gen 3.

Yes, but it doesn't have onboard graphics.

Yes, but it doesn't have onboard graphics.

So is it just because it has onboard graphics? Like Does a 7 3700x support gen 4.0 gpu speeds and gen 4.0 nvmes speeds?

 

[boju]

Yes it does

But you would be better off going 5700x, 5th series in general, for superior performance.

No, the underlying chips are physically different and made in different batches. G chips are actually designed for budget builds with no graphics cards, so they made them as cheap to make as possible. Only giving them the capabilities they need to work well in their intended role. Don't need a lot of PCIe expansion if your won't necessarily be using a GPU, and if you do, likely a budget option again, no need for high bandwidth.
