PCIe 4.0 doubles the bandwidth of 3.0, the current standard; 5.0 doubles the bandwidth of 4.0 again. Additional CPU PCIe lanes give both your GPU and SSD access to CPU lanes. Upgrading to a PCIe 4.0 SSD prepares your system for new gaming innovations like DirectStorage. Every generation of PCIe is backwards compatible.
PCIe 4.0, also known as PCIe Gen 4, is the fourth generation of Peripheral Component Interconnect Express (PCIe) expansion bus specifications, which are developed, published, and maintained by the PCI Special Interest Group (PCI-SIG).
Is PCIe 4.0 worth it for SSDs? If you want the absolute fastest drives available, then PCIe 4.0 SSDs are the way to go. They're quicker than any PCIe 3.0 drive and will make large file transfers for such things as video editing lightning fast.
What is the PCIe 3.0 and PCIe 4.0 speed? As pointed out above, the PCIe 4.0 has a 16 GT/s data transfer rate, while PCIe 3.0 has 8 GT/s. So, the PCIe 4.0 speed is twice as fast as PCIe 3.0. In addition, different lane configurations have different bandwidths.

But while PCIe 4.0 setups outperform 3.0 in synthetic benchmarks, the real-world benefits for gaming are currently minor. Some tests suggest that even running games in 4K with current graphics cards won't saturate the bandwidth of a PCIe 3.0 x16 slot.
In a nutshell, right now PCIe 4.0 does little to improve performance with the RTX 3080. It's possible that could change with future games, but for now it's a non-issue.
Short answer: No. Longer answer: Unless you've got leftover budget and a good reason to burn it, PCIe 4.0 isn't likely worth buying into for a gaming system right now. For gaming, few graphics cards support PCIe 4.0 right now.
While NVIDIA's GeForce RTX 3070 GPU works just fine with PCIe 3.0 slots, it's best to grab a motherboard with a PCIe 4.0 slot to make the most of its graphical prowess.
From the gaming perspective, you don't really need to care about PCIe 4 just yet. The gaming performance of most modern GPUs doesn't fully saturate the PCI 3 bandwidth as of now. Even loading games on PCIe 4 NVMe drive doesn't have a noticeable impact compared to Gen 3.
NVMe will be the protocol of choice for the next generation of storage technologies such as 3D XPoint. PCIe 4.0 refers to the fourth generation of PCIe interface which has double the bandwidth (64GB/s for a x16 slot) compared to PCIe 3.0 (32GB/s for a x16 slot), which is the usual improvement between PCIe generations.
PCIe SSDs are faster than SATA SSDs.
PCIe 4.0 enables a more robust equalization. In term of performance, with PCIe 4.0, throughput per lane is 16 GT/s. The link is full duplex, which means the data can be sent and received simultaneously à Total Bandwidth: 32GT/s.
A PCIe 4.0 graphics card will work in a PCIe 3.0 motherboard slot at PCIe 3.0 speeds. For PCIe 4.0 graphics cards, maximum graphics throughput can only barely exceed that of PCIe 3.0. For this reason, the benefits of upgrading your motherboard to PCIe 4.0 will be minor.
As of now, only Intel's new Alder Lake CPUs and compatible motherboards have PCIe 5.0 support. AMD's upcoming 7000 series processors will also bring PCIe 5.0 support later this year and that's when we expect more consumer-grade PCIe Gen 5 peripherals to hit the market.
A PCIe 4.0 NVMe SSD will work in a PCIe 3.0 M. 2 motherboard slot at PCIe 3.0 speeds. PCI-Express versions are backward compatible, meaning that you can use a PCIe 4.0 graphics card or storage device on a PCIe 3.0 or PCIe 2.0 system.

When you're planning a PC, choosing the right case can make or break the build. You should commonly find either full-sized cases, mid-sized cases, or mini-ITX cases. Full- and mid-sized cases shouldn't have issues fitting the new RTX 3070 and 3080 GPUs, and even the RTX 3090 should fit into some mid-sized cases.
Yes. It will work with B450.
Likewise, PCIe 4.0 x16 refers to a Gen 4 expansion card or slot with a 16-lane configuration. And so on. Each new PCI Express generation doubles the amount of bandwidth each slot configuration can support. That's why the configurations are expressed in multiples of two.
Yes, the RTX 30XX will work with PCIe 3.0.
The GeForce RTX 3080, rated for 320W, makes do with a pair of 8-pin PCIe power connectors.
Nvidia RTX 3080 Ti vs RTX 3080: performance
In 4K gaming, the RTX 3080 Ti breaks away from the RTX 3080, providing a nearly 10% performance difference. For instance, it is able to get 95 fps in Dirt 5 at 4K with all the settings maxed, where the original RTX 3080 gets 86 fps.
The main benefit of PCIe 4.0 SSDs being faster not only gives quicker loading times in some games, but it also translates to a much snappier operating system. You can expect instantaneous boot times with the latest NVMe drives if it houses your Windows, Linux, or macOS and fast loading of programs.
What is PCIe or PCI Express? PCIe is short for “peripheral component interconnect express” and it's primarily used as a standardized interface for motherboard components including graphics, memory, and storage.
