The new PCIe 7.0 x16 standard will offer up to 512GB/sec bi-directionally, and while your GPU would be sitting on its hands at that point -- graphics cards of today don't need the wicked fast upgraded speeds we're getting with PCIe 5.0, PCIe 6.0, and the just-announced PCIe 7.0 -- the new speeds will be a boon for HPC, AI, and supercomputers.
This means we're going to see next-gen PCIe 7.0 x4 NVMe M.2 SSD of the future pushing a huge 128GB/sec -- up from the 64GB/sec on PCIe 6.0 x4, the 32GB/sec on PCIe 5.0 x4, the 16GB/sec on PCIe 4.0 x4, and 8GB/sec on PCIe 3.0 x4. 128 gigabytes per second, transferring on that tiny M.2 SSD on your motherboard.
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 the low-latency and high-reliability targets
Improving power efficiency
Maintaining backwards compatibility with all previous generations of PCIe technology
