A 12 months in the past, we analyzed NVIDIA Resizable BAR efficiency on an unsupported Intel Z390 CPU platform, so now we are going to take a look at this function on an formally supported Z690/12900K platform to see if it’s value it. We benchmark this function, on versus off, utilizing our newest beneficial GeForce driver, the newest model of Home windows 11, and 9 NVIDIA white-listed PC video games that are a part of our testing suite.

Notes on NVIDIA Resizable BAR

To make use of NVIDIA Resizable BAR, customers want a GeForce RTX 30 Collection graphics card with a supported VBIOS, a suitable CPU, a suitable motherboard and SBIOS, and GeForce 465.89 driver onwards. With these necessities met, it’s essential to allow Resizable BAR in your motherboard’s UEFI setup program and boot your PC in UEFI mode with CSM disabled for UEFI GOP assist.

Supply: NVIDIA

Whereas the checklist above doesn’t particularly point out our Z690 platform, we requested NVIDIA straight, they usually confirmed it formally helps Resizable BAR. So on this evaluate, we are going to see how the next NVIDIA’s phrases apply to our Z690 platform or comparable formally supported configurations:

” … NVIDIA will likely be pre-testing titles and utilizing sport profiles to allow Resizable BAR solely when it has a optimistic efficiency impression. That approach you gained’t have to fret about bugs or efficiency decreases, and gained’t need to depend on the group to benchmark every title and uncover whether or not Resizable BAR is helpful within the video games you’re enjoying.” (Supply)

How To Examine the NVIDIA Resizable BAR Function State

You’ll be able to verify if Resizable BAR is enabled utilizing GPU-Z, the NVIDIA Management Panel, and Home windows System Supervisor. Under you’ll be able to see what our testing system reviews when Resizable BAR is enabled utilizing the talked about strategies:

GPU-Z, NVIDIA Management Panel, and Home windows System Supervisor report that our system has Resizable BAR enabled.

Our testing platform is a latest set up of Home windows 11 64-bit Professional Version, an i9-12900K with inventory clocks, an ASUS PRIME Z690-P D4 motherboard, and 32GB of T-FORCE XTREEM ARGB WHITE DDR4 3600MHz. The video games examined, settings, {hardware}, GeForce drivers, and Home windows 11 construct are an identical aside from the off versus on ‘Resizable BAR’ state we evaluate. We enabled and disabled Resizable BAR utilizing the UEFI setup program for our testing.

Earlier than providing the efficiency knowledge and charts of every completely different evaluation situation, it’s essential to explain each the {hardware} and software program configuration utilized in our testing, in addition to the evaluation methodology.
