From PC World: Are you ready for PCIe version 6.0? No? Your motherboard doesn’t even have PCIe 5.0 yet, because you’re squeezing every last possible ounce of value out of AM4? Well too bad, because PCie 7.0 is now on the horizon. And while it’s still a ways off — the final version of the spec won’t be available until next year — the speed it’s offering will be mind-blowing.
We’re talkin’ up to 512 gigabits of data per second when using x16 lanes on a fully-open motherboard slot, double the prospective speed of PCIe 6 and four times the speed of PCIe 5. So sayeth the Peripheral Component Interconnect Special Interest Group, better known as PCI-SIG. The group has released its 0.5 spec for members, according to a public post spotted by AnandTech.
PCI-SIG doubled down on its stated goals for the final version of PCIe 7.0, a little less than two years after its announcement. According to the blog post, these include:
- Delivering 128 GT/s raw bit rate and up to 512 GB/s bi-directionally via x16 configuration
- Utilizing PAM4 (Pulse Amplitude Modulation with 4 levels) signaling
- Focusing on the channel parameters and reach
- Continuing to deliver low-latency and high-reliability targets
- Improving power efficiency
- Maintaining backwards compatibility with all previous generations of PCIe technology
