Hello everyone. I’m Butterfly Technology. This issue is about AMD and Intel’s two fairy fights.
If you have time, please pay attention to the WeChat official account, which is also Butterfly Technology.
On AMD’s 7nm third-generation Ryzen and X570 chipsets, PCIE4.0 is a very important technology. The bandwidth of up to 32GB/S is doubled compared to the current PCIE3.0.
AMD’s RX5000 series graphics cards and SSD hard drives controlled by Phison and Huirong will be the first to join PCIE4.0 support
At present, AMD is leading the PCIE4.0 technology, but Intel strongly doubts this. From the Taipei Computer Show to the E3 Game Show, the "PCIE4.0 is useless theory" has been repeatedly raised, especially in games, according to Intel’s The test, let alone the ultra-high bandwidth of PCIE4.0, is the upgrade from PCIE3.0 x8 to x16, the bandwidth has not improved the performance of any game
On average, the performance impact is only 0.0099%, this gap may be Even the error cannot be counted. How does Intel eagerly prove that "PCIE4.0 is useless" So what does AMD think?
At a recent media conference in Korea, David Mcafee, the director of AMD’s processor development department, also did Explanation. He said, "At present, PCIE3.0 is indeed sufficient for game use, but whether to support PCIE4.0 is a question of whether it is a chicken or an egg. Game developers have not yet supported PCIE4.0 because it isFor the first time, consumer-grade motherboards and CPUs support PCIE4.0, so there will be no significant performance improvement temporarily using PCIE4.0. "Even if the current benefits are not great, but after AMD supports these functions, once future storage devices or PCIE cards have bandwidth requirements, it is very important to support PCIE4.0 in advance."
Judging from the statement by the director of the CPU development department, his attitude towards PCIE4.0 is similar to that of Donny from the Ryzen Technology Marketing Department and the product management head of the Radeon Department.
"If everyone is thinking Wait until you need to develop new technologies. Then there will be no new technologies in the next ten years, so you have to promote it, and users will naturally follow up, and immediately all storage vendors will follow up together."
