to test it you need to take the same card and run it in gen 3 and gen 4

"How much extra graphics performance can you get from PCI gen 4 versus gen 3?" Umm, NONE as it stands right now. PCI-E bandwidth will only be a factor (between Gen 3 and Gen 4) if the device is saturating it. Current graphics cards in a PCI-E 3.0 x16 slot don't even come close to saturating that link, so putting that same graphics card into a PCI-E 4.0 x16 slot will not result in a performance gain. This IS, on the other hand, a big leap in performance potential for NVMe storage, which is currently saturating existing PCI-E interfaces.

Are you able to install a PCIe 4. 0 card into a PCIe 3. 0 slot??

If the 5700 could barely best the 2070 how can it beat the 2080 to?

Does it worth to pay more for a b550 motherboard just for the pcie 4.0 GPU slot? I'm going to buy a new pc, so I have to consider this things... I don't plan to use PCIE SSDs. I'm only worried about GPU speeds.

This is not a conclusive test. you need to compare apples to apples. Run the Radeon RX 5700 XT on both systems. this way your testing the same hardware against the different buses. This is basic stuff, a Manufacture should know this. If you run a PCI-E 4.0 card such as the RX 5700 XT with it's 448GB/s in a PCI-E 3.0 Bus, you can attempt to saturate it, although it won't be enough stress, so likely won't show much difference from a practical standpoint such as actual gameplay. 3D Mark is strictly synthetic and fun to watch, but best to show actual in-game footage like they did with Battlefield for Ryzen Launch. This will show if the new Gen RX 5700 actually makes a difference on PCI-E 4.0 v.s 3.0... but still not conclusive, as too many other factors such as chipset enhancements on the X570 Platform, Ryzen 3 Gen performance enhancements, etc.. . without Intel having a PCI-E 4.0 platform to compare, it's hard to say if the performance gain is strictly from the PCI-E Bus.. as i don't think Nvidia would have designed the GTX 2080 Ti with 616GB/s if the PCI-E 3.0 platform couldn't handle it. there is too many different factors with the hardware in the test to claim such a naive statement that PCI-E 4.0 is that much faster, when we don't fully saturate our current tech. great for marketing to noobs though lol

Not a great demonstration but it'll do I suppose.

amd ryzen 7 3800x > i9 9900k amd is slaying intel atm

Thats just a Particle Demo that utilizes the PCIe 4, 0 bandwidth and not a
fully 3D Render scene for what ever or a Game until GPUs can reach this
speeds to fully utilize a pcie 4.0 slot for sure 4-5 years will pass
like not even the next generation example GTX 3080 wont fully utilize
pcie 4.0 maybe just 30% the next generation after it maybe then....

[eraserheads]

Thank you AMD for giving us a choice. God bless AMD.

Yep PCIe Gen 4 is better, but this demo doesn't show that, in fact this demo is just a bunch of fake bullshit. The 5700 XT doesn't even come close to saturating PCIE Gen 3. Great for upgradability, but the fact that they even thought for a 'second' that it wasn't totally misleading and bullshit marketing to put Nvidia and Intel on the PCIE comparison proves they really are just using it as a marketing device and don't actually give a fuck about their consumers having better performance.

Don't get me wrong, Ryzen CPU's are BEAST for HEDT users, and that's all well and good, but if that's your target audience who gives a fuck about the GPUs they're showing which are CLEARLY targeted at gamers who will see ZERO benefit from this technology for a few generations by which time Nvidia and intel based cards will also be running on Gen 4 rendering the argument completely moot. The ONLY way Gen 4 right now benefits AMD as a valid marketing item is if you're talking about Gen 4 PCIe M.2 SSD's and then ONLY for very very limited HEDT use cases that require absolutely MASSIVE sequential read/write performance that basically doesn't exist, and could be created with RAID just as easy. Literally the only use case where this actually matters to those consumers is a virtual machine farm off a single computer running a massive Gen 4 SSD raid array... At which point you're in the server space, and again it's totally moot.

In other words... It's totally moot. Period. Even where the use case actually exists it's inferior to already existing solutions in different markets, so it's completely meaningless. Don't get me wrong, I'm happy they added it, but it should be a 'side note' regarding upgrade-ability, not focused on in this bullshit segment the way it was.
