PCI Express 7.0 is advertised as 4x faster than PCIe 5.0

Few real winning scenarios for desktop consumers

PCI-SIG, the industry consortium responsible for defining the PCI-Express bus specification, officially announced PCI-Express 7.0, or just PCIe 7.0, which will be officially released in 2025. As with every new version, PCIe 7.0 doubles the data transfer capacity compared to PCIe 6.0 to 128 GT/s and a maximum transfer rate of 512 GB/s bidirectional transfer via x16 slot, very high numbers should There will be real benefits, especially for SSDs and data networking.

As key highlights of PCI-Express 7.0, we have:
– Maximum bit rate 128 GT/s and 512 GB/s bidirectional via PCI-Express x16
– PAM4 system (4-level pulse amplitude modulation)
– Focus on channel parameters and commitment coverage
– Low latency and high reliability
– better energy efficiency
– Compatible with all previous generations of PCIe

PCIe 7.0 is 4x faster than PCIe 5.0 just launched

The table below shows the specification progression for all versions of the PCI-Express bus, which is 64 times faster in PCIe 7.0 than in PCIe 1.0. Note that in PCIe 7.0, PCI-Express x4 cards can achieve the same speed acceleration PCIe 5.0 x16.

With the PCI-Express 7.0 specification, PCI-SIG believes it will provide advanced solutions for emerging applications such as 800G data networking, quantum computing, data-intensive data centers, high-performance computing, military and aerospace, and more.

The PCI-Express bus is currently the best solution for high-demand data traffic as it advances with each new release. As a comparison, PCI-Express 5.0 (PCIe 5.0) has effectively entered the consumer market recently, and few solutions are able to reap the real benefits, as mentioned above. SSDs (Solid State Storage Drives) are among the products that benefit from this advancement, but in very specific usage scenarios. Who can take advantage of such a fast SSD? Especially data centers with servers that require high data traffic. For traditional consumers, PCIe 4.0 SSDs already offer incredible speeds, with the latest models exceeding 7000 MB/s.

It’s also worth mentioning that the graphics card has also been updated to support the new PCI-Express bus, but when considering models based on the x16 slot, that doesn’t traditionally bring real performance gains, not even versions like PCIe 3.0 x16. Limit the performance of the chip. However, the new buses have improved the speed of solutions such as x8, x4, etc., providing better performance for cards based on these buses, and this is precisely the limitation. Another detail is that the faster bus “supports more energy”, so a solution powered by the bus is possible without the need for a power cord.

PCIe 5.0 solutions are just coming to market, PCIe 7.0 is a few years away

Bringing PCI-Express to the computing world, the first models to support PCIe 5.0 recently hit the market with Intel’s 12th Gen Core. AMD will implement the same bus in new Ryzen 7000-series models arriving later this year.

There is still no official forecast for a solution that adopts PCIe 6.0 to hit the consumer market, let alone PCIe 7.0, which may take years.
