Intel Corporation Peripheral Component Interconnect standard developed by (PCI), is an industry-standard, high-speed bus found in nearly all desktop computers. Graphics cards, sound cards, network cards It is used in many components such as. A date has been given for version 7.0 of PCI Express technology, whose new version has been awaited for a long time.
PCI Express 7.0 coming in 2025
PCI Express 7.0 first introduced in 2022. However, the process of working on it continued. Version 0.3 of the specification was released in mid-2023 and has now been upgraded to PCI-SIG version 0.5. The full version is expected to be released in 2025.
This is a good thing, the consumer market still sees increasing adoption of PCIe 5.0 and PCIe 6.0 is the focus going forward. Each new version doubles the bandwidth of the previous one. PCIe 7.0 per second 128 gigs It aims to transfer. Depending on the configuration this may be possible with x16 connectivity 512GB/s or via x1 connection 32GB/s It may mean.
Basically, you can halve the number of lanes to get the same speed with each new generation, or double the speed on the same number of lanes. Nvidia RTX 4090 It even uses PCIe 4.0 slot. The same goes for the AMD Radeon RX 7900 XTX. As we said, the transition to 5.0 is still ongoing and we are likely to see it in the new generation cards.
NVIDIA introduced the world’s best artificial intelligence chip! Here are the features
NVIDIA Blackwell B200 artificial intelligence chip was introduced. The company says it has developed the most powerful artificial intelligence chip ever.
A PCIe 4.0 x16 link only handles transfer speeds of 64 GB/s; PCIe 7.0 will be able to do this with only 2 lanes. In this way, there will be a huge leap in data transfer speeds. Of course, it will be a long time before we see PCIe 7.0 hardware in consumer products.
This will appear first on servers for applications that need to move large amounts of data. PCI-SIG expects the new standard to be used in 800G Ethernet, AI/Machine learning devices, cloud servers and even quantum computers.
We can list the goals of PCI Express 7.0 as follows:
- Delivering 128 GT/s raw bitrate and up to 512 GB/s bi-directionally via x16 configuration.
- Using PAM4 (4-level Pulse Amplitude Modulation) signal
- Focus on channel parameters and reach
- Deliver low latency and high reliability targets
- Improving power efficiency
- Maintaining backwards compatibility with all previous generations of PCIe technology.
