Here’s why PCIe 7 will be a major upgrade when it comes to your PC

PCIexpress 7, or PCIe 7, is the next (next) generation of PCI Express technology that will increase the available bandwidth for all add-in cards on your desktop PC. I know, I know — you may still be working on upgrading to PCIe 5. Don’t worry, this one’s at least a couple of years away.

But when it does land, it promises to unlock the potential for even greater graphics performance, and open up future generation NVMe SSDs for even faster read and write speeds. In total, it’ll quadruple the available bandwidth over existing PCIe 5 slots, along with making improvements to efficiency and latency. Here’s everything we know about PCI Express 7 so far.

What is PCIe 7?

PCI Express 7 is an upcoming generation of expansion port for computer motherboards. It’s an advanced version of existing PCI Express connectors that allow graphics cards and other add-in cards, like USB hubs and high-speed network cards, to connect to the computer.

The latest publicly available generation of PCI Express technology at the time of writing is PCIe 5. It’s found on some motherboards and there is a limited range of NVMe SSDs which can utilize its high-bandwidth connection. Modern graphics cards are compatible with PCIe 5, but they do not require it to run at peak performance.

The next-generation of PCI Express will be PCIe 6, with PCIe 7 set to follow it sometime later.

How fast is PCIe 7?

PCIexpress 7’s has a per lane transfer rate of 128 Gbps. That’s double that of PCIe 6, and quadruple that of PCIe 5.

In a standard graphics card x16 slot, this would work out to a total bandwidth of 512 GBps. The PCI SIG interest group that defines and develops PCIe technology, claims that PCIe 7 will also benefit from reduced latency and improved power efficiency. It will also be backward compatible with all previous generations of PCIe technology.

PCI SIG believes that PCIe 7 will be utilized for high-end graphics cards, but also for enabling up to 800 Gbps Ethernet connections, and artificial intelligence calculations.

A big benefit of this high per-lane data rate, however, will be in enabling higher-speed connections in smaller PCIe slots. A PCIe 7 x1 slot will offer the same bandwidth as a PCIe 4 x16 slot, making it possible for high-speed drives and even graphics cards to utilize smaller PCIe connections for more compact computing.

When will PCIe 7 be available?

PCIe 6 was announced in 2022 and will see the first products and devices that support its debut towards the end of 2023. PCIe 7 is currently slated for a 2025 debut, so it may not be until 2026 that we see the first PCIe 7 supporting products launch.

This ‘Swiss Army Knife’ app transformed how I play PC games
A monitor showing the Special K mod in Elden Ring.

Most PC games aren't perfect. I'd go as far to say that most of them have problems -- especially considering the disastrous PC launches we've seen this year. If a game is popular enough, and open enough, you can lean on community mods to get your game in a better state. But what if there was an app that could help your performance and add missing features to all of your PC games?

There is, and it's called Special K from developer Kaldaien. It was originally created as a tool to fix the issues in the PC releases of Fallout 4 and Batman: Arkham Knight, the latter of which is one of the worst PC ports of all time. Since then, it has grown tremendously into a self-proclaimed "Swiss Army Knife" for PC game modding.

This Razer 27-inch QHD gaming monitor just got a massive discount
Playing a game on the Razer Raptor gaming monitor.

Razer has a reputation for making some of the best gaming laptops and peripherals on the market and is often viewed as the high-end equivalent of the gaming market, in the same vein as Apple or Mercedes. What you may not know is that Razer also makes high-end gaming monitors, and the Razer Raptor 27 is an excellent example of it, as it has a lot of great features under the hood that any gamer would love. While it usually comes at the steep cost of $800, Razer is offering a massive discount on it of %50, meaning you can grab the Raptor 27 for just $400, which is a steal.

Why you should buy the Razer Raptor 27
Right off the bat, one of the things that let the Raptor 27 compete with the best gaming monitors is the impressive 165Hz refresh rate at 1440p resolution. That means you get a lot of room to adjust whether you want a higher resolution for single-layer games or a higher refresh rate for multiplayer and action-packed games where each frame counts. Or, if you have one of the best GPUs right now, such as the AMD Radeon RX 7900 XTX, you can easily push both the refresh rate and resolution to their limits, even on the highest graphical settings.

Insane deal knocks $900 off the Razer Blade 17 gaming laptop
Razer Blade 17 on a table.

Razer is known for making some of the best laptops in the market, although they're equally well-known for being a high-end brand that is often quite expensive. Even so, if you're looking for a unique laptop, Razer is probably where you'd look, and in this case, if you want one of the best 17-inch gaming laptops, you'd be hard-pressed to find one better than the Razer Blade 17. Of course, it does come at a pretty penny, although Razer is running a great deal right now that discounts the Blade 17 down to $2,300 rather than the usual $3,200, a significant 28% discount.

Why you should buy the Razer Blade 17
Probably one of the first things you'll want to know about this Razer Blade 17 is what sort of GPU it runs, and we're happy to report that you'll find the relatively powerful RTX 3070 Ti under the hood. That's a card that can provide reasonably good 4k performance, which is good because the Blade 17 comes with a gorgeous 17-inch 2k resolution panel. As such, the RTX 3070Ti will easily run most games on high resolution and graphical settings without much issue. The panel also has a very impressive 240Hz refresh rate, which means that if you're going to be playing competitive or action-packed games where each frame counts, you can get some high refresh rates from the RTX 3070 Ti, with a few graphical compromises, of course.
