1 with double the bandwidth of PCIe 4.0

In late October 2021, Intel officially lifted the ban based on the new architecture AlderLake build-generation Core processor –12, with 12 daikurui debut together, there are a number of cutting-edge technology, such as DDR5 and PCIe5.0. In recent years, with respect to the circle of discussion uproar DDR5 memory, PCIe5.0 clearly more be called a true “forward-looking”, you know PCIe4.0 it appeared not long, the layout of the related products still remain in the high-end solid-state hard drive and new graphics, PCIe5.0 sudden emergence can describe.

Today will be equipped with a high-end Z690 motherboards support the PCI-Ex16 slot PCIe5.0

PCIe 5.0 will undoubtedly have a stronger performance than PCIe 4.0, in addition to performance soaring outside, PCIe 5.0 which have outstanding contributions in the scenario? For ordinary consumers and what value you can bring? This article will focus on the performance PCIe5.0, commercial and consumer-oriented application scenarios scenarios unfold in these areas, to you on this technology in the end the “new” where, why we believe that consumers should be allowed at this stage PCIe 5.0 the “bullets fly again for a while”, I want to learn this new technique of small partners do not miss Oh ~

Bandwidth

According to PCI-SIG plans, each generation PCIe update will make double or nearly double the bandwidth, such as PCIe4.0 can provide bandwidth 16GT / s, and doubled in PCIe3.0, as the successor of PCIe4.0, PCie5 .0 bandwidth is arrived 32GT / s, this data is to double PCIe4.0, the transmission rate per channel up to 3.94GB / s, 16 arranged at a total rate of passage will reach exaggerated 63GB / s.

PCIe5.0 standard final version already released in May 29, 2019, the final version of the standard than PCIe4.0 Published June 8, 2017 a difference of only two years, and in previous years, 3–5-year update cycle compared to this very short time interval, means that nuclear hardware vendors and users may also face PCIe3.0, PCIe4.0 and PCI5.0 three interfaces.

Support PCIe5.0 equipment Z690 has finally come out, but the interface is still mired in PCIe4.0 M.2 and PCIe3.0

Higher bandwidth can obviously bring more possibilities, but also know that even the current card Wong RTX3090 still can not let PCIe4.0 saturation, talk about PCIe5.0 applications may be more future-oriented outlook, while PCIe5.0 ahead appears also to PCIe4.0 in a rather awkward position – if there are future introduction of necessary PCIe4.0 products? If you push PCIe4.0 new products, then it is to continue as a flagship appear, or in the form of popular art happen? Perhaps this issue will be surrounded by storage vendors in this transition period.

More interesting is that the current Z690 motherboards are not given on the interface PCIe5.0 M.2, but some manufacturers such as ASUS, part of the brand’s high-end models motherboard will be bundled PCIe5.0 SSD adapter, it can be considered to high-end users an explanation. As for graphics developers, they should have no concerns in this regard, after all RTX30 series and RX6000 series has universal coverage PCIe4.0, the next-generation graphics conference next year, the two giants (count Intel’s new card is perhaps the Big Three? ) Do not be surprised when announced new card supports PCIe5.0.

Although 12 daikurui the recent lifting of the ban before the official release, the relevant products are basically civilian-level PCIe5.0 yet, but business-oriented PCIe5.0 products have gradually appeared.

At present civilian areas only high-end Z690 series motherboards support PCIe5.0

Here to share a “cold knowledge”, “Big Blue” IBM in October 2020 already supports PCIe5.0 for the release of the commercial area POWER10 processor, general server product life cycle 4–5 years, then the product will gradually eliminate 20% to 25%, so the first batch of PCIe5.0 product is clearly oriented commercial. For example, some time ago the official release of Man armor, armor Xia solid state drive for data center and support PCIe5.0 of CD7, this product go PCIe 5.0×4 channel, the maximum read speed of up to 14GB / s, twice the current of PCIe 4.0 solid-state flagship product, is undoubtedly a performance beast.

From the chart to see the products, Xia armor thermal specifications CD7 quite high

As for the direction of civilian products, currently supports only PCIe5.0 motherboard Z690 series of choices for consumers, NVIDIA’s next-generation game graphics RTX40 series is expected to be supported PCIe5.0, but universal need two X86 processor developer together this standard will bring more on board. Red team is expected to next year will be compatible PCIe5.0 AM5 on the motherboard, so next year we should at least have not been able to see PCIe5.0 product contending grand occasion in the civilian market.

They are around the front of the main topics discussed PCIe5.0 the technology itself, but also easy to use technology and then landing to see the efficacy of this technique is so powerful and can bring any value? There is a general consensus that, PCIe5.0 of ultra-high bandwidth can show its mettle on AI and cloud applications.

Source network

AI applications often need to generate vast amounts of data, requires immediate processing and data transmission, the size of the rapid expansion of machine learning models in a short time, which the storage device generates a greater pressure, the storage device support of PCIe5.0 AI can help to like this kind of calculation-intensive work more efficient running, the bottleneck between the liberation of equipment and systems.

Similar needs arise in cloud computing, currently 100Gbps, 200Gbps Ethernet backbone road has emerged, PCIe5.0 is bound to release the bottleneck server, so that transmission capacity to keep up with the speed backbone. In the field of high-throughput applications, such as fast on autopilot and defense systems, PCIe5.0 equally important role to play.

What is the impact on consumers

As for the consumer side, now we can imagine the scenario is the most intuitive Microsoft DirectStorage technology for the gaming industry, this is a worthwhile dubbed “innovative,” the title of the technology, which consists of three parts, API is the application programming interface, GPU acceleration data compression and storage system underlying stack optimization.

In which high-speed solid-state hard disk data compression GPU acceleration technology will play an important role this technology can refer RTXIO NVIDIA technology has been released, which uses the PCIe bus this high-speed data channel to feed the GPU, so as to reduce CPU work, which DirectStorage technology is hardware implementation. This technology has been applied in the latest Xbox series host, comprehensive logging onto the PC just a matter of time. Currently requires the use of PCIe3.0 or more hard disk drives with DX12Ultimate compatible graphics card, its existence will eliminate read “annoying” wait strip.

In addition, thanks PCIe5.0 four times the bandwidth of PCIe3.0, PCIe5.0x4 PCIe3.0x16 that is to have the same performance, maybe we can see more micro-compact PCIe devices in the future.

Summarize

Admittedly, PCIe5.0 technology will portray a better future, as PCIe5.0 into the commercial realm, based on this technology brings efficiency gains are expected to bring more positive impact on our lives.

But for the civilian areas, high calorific value equipment will be our main object of attention, think of the cooling vest has become PCIe4.0 solid state drive “standard”, faster hard drives may be cooling PCIe5.0 have higher expectations perhaps this will encourage manufacturers to use technology to create higher-level controller chips. Currently PCIe5.0 civilian products from landing there is a long time, and support the technology board just published, there is a long distance popularity of distance, we as consumers may wish to wait and see.
