PCIe 4.0 is an important part of the 7-nm Revlon 3000 and RX 5700 graphics cards. It is also an important part of RX 5700 graphics cards.AMDFocus of propaganda. For the advantages of PCIe 4.0 technology, AMD gives three technical advantages:

The speed is faster, with the x16 bidirectional bandwidth up to 32 GB/ s, twice the PCIe 3.0.

Downward compatible, PCIe 4.0 is also compatible with PCIe 3.0 devices.

With more connectivity, PCIe 4.0 bandwidth,1 top 2, can connect more devices without worrying about performance degradation.

For the bandwidth advantage of doubling PCIe 4.0, it is not easy for ordinary consumers to experience it now, except that PCIe 4.0 hard disk can take advantage of the high bandwidth of PCIe 4.0. But we can't be like that either.IntelThat denies the value of PCIe 4.0. After all, it's normal to lack terminal product support when new technologies come out, just like 5G now.Mobile phoneLess and more expensive.

The question is how does AMD consider PCIe 4.0? New Egg recently interviewed two executives of AMD, Donny Woligroski of Ruilong Technology Marketing Department and Mithun Chandrasekhar, head of product management of Radeon Department, who introduced AMD's concept of PCIe 4.0 technology.

For the value of PCIe 4.0 to users, Donny Woligroski says that players who need higher bandwidth are often the core users. Running NVMe RAID can tell the difference from PCIe 3.0. In addition to this, PCIe 4.0 is more like a leading technology demonstration.

Someone will say, "We don't need it yet," but if everyone wants to wait until they need it, the new technology won't be available for 10 years, so you need to push it, and then (the user) comes, all storage vendors will follow up immediately, and AMD's Radden department will soon have the first PCIe 4.0 graphics card.

Of course, Donny Woligroski said that this does not mean that everyone has to buy X570, you can also buy X470, B450, which is just a choice.

Mithun Chandrasekhar of Radeon also adds to the significance of PCIe 4.0.He pointed out that Intel had not really innovated in technology for a long time. Even their high-end CPUs were 4 cores and 8 threads. It was not until the emergence of AMD's Sharon processor that everything began to change. Suddenly the game developer found out, "Wow, now I can use 8 kernels, 12 kernels or even 16 kernels, and I can do something meaningful."

Similarly, PCIe 3.0 has been the mainstream standard for many years. AMD hopes to play a leading role. Therefore, for RX 5700, AMD believes that this is the best time to upgrade to PCIe 4.0. 3D Mark has now supported the test of PCIe 4.0. As you can see, compared with PCIe 3.0, the bandwidth of PCIe 4.0 almost doubles.

At present, this is still theoretical. For games, PCIe 4.0 will be popular for some time. Game developers need to see more GPUs to take advantage of the extra bandwidth.

However, on the current content creation platform, compared with PCIe 3.0, DaVinci Resolve can create 8K 60fps content on RX 3 and RX 5700 graphics cards, which is incredible.
