Intel ready to take on "Smart Access Memory" with Resizable BAR support (pcinvasion.com)
 
Things are about to get better for gamers thanks to the swift standardization of the PCIe Resizable BAR feature. AMD led the charge last year with its “Smart Access Memory,” which required both a Ryzen 5000 CPU and RX 6000 GPU in order to make the feature work. Intel and Nvidia were not pleased to learn about the competitive edge, however. Both companies quickly promised to deliver versions of the feature, which they referred to as Resizable BAR. Intel is now ready to deliver on that promise, and officially announced Resizable BAR support for its 11th gen CPUs.Intel GM Fredrik Hamberger announced the feature in a recent discussion with Tom’s Hardware. Hamberger discussed the process of working with both Nvidia and AMD to develop Resizable BAR support, and referred to it as more of a standardization rather than a premium Intel feature. The suggestion is accurate too, because Resizable BAR has apparently been around since PCIe 3.0, but went unutilized until recently.
 
The standardization of Resizable BAR means that gamers will be able to achieve 5-10% better performance in games simply by using the feature. According to Nvidia, the feature allows the CPU to “efficiently access the entire frame buffer,” while moving through levels and open-world environments. It’s an exciting “extra” to go along with the improved architectures and manufacturing processes that allow for better gaming experiences. Tack on things like Nvidia’s DLSS software, and cutting-edge hardware sure does sound attractive.
 
Intel suggested that some 10th gen products are technically able to leverage Resizable BAR, though exact details on what to expect have not been released. Whatever the case, Intel expects OEMs to finish updating custom drivers for 11th gen CPUs to include support for Resizable BAR in the near future. Gamers can look forward to support on both desktops and laptops. Once Resizable BAR becomes widely available, it should be possible to mix and match between AMD, Intel, and Nvidia hardware configurations that support it.
 
I'm happy to see Intel supporting this going forward. 

While resizeable BAR is unlocked on z390, z490, and x299, I don’t think I have seen any testing to show how much it helps on any of those platforms. All we know is that it helps get AMD products a few percentage of improvement, but maybe with 11th gen it will have better support from the beginning, meaning it is leveraged properly.

NVidia hasn’t released bios updates or driver support so the testing platform ability is incredibly limited.

This is cool don't know if i'll go with the hardware though

Is this really going to do anything for FPS or just marketing ploy?

Tests that I have seen had as a result, depending on the game, sometimes more or less impact. Primarily the min fps are increased (depending on the game 10-40fps). The max FPS increase slightly (~ 1-10) and the average is 3 to 20 fps. So fluctuating strongly! For some games it is absolutely negligible, for others it is a clear plus. The tests that I use here from the results even refer to a Ryzen 9 3900x cpu paired with an amd card. (6800, 6800xt, 6900xt) I.e. it could probably even bring more or less depending on the GPU. I haven't researched intensively. Resolution was 1440p. Time will tell what it looks like with nvidia cards. I don't know if there are differences between the old cpus and the latest 5000 ryzen.
 
AMD himself said that it only brings a slight plus for games without special use of the features, but if it is specially programmed for it, it brings even more.

Still nice to get a little bonus where you can. I do like how AMD tries to get what it can in that respect. Forces Intel to do the same.
