Nvidia Re-Size Bar/SAM support is live for some cards, more in March - 10% performance gains

Wonder if the cost of upgrading my motherboard just to support RBAR is worth it? But then will the 3700x, compatible mobo and RTX 3080 support it with games anytime soon? And would the performance improvement of RBAR be worth the actual outlay of a new motherboard? Seems a tricky decision.

Also have to factor the cost of spending money on an old design as the next CPU I but I don't think it'll be AM4 socket.

I'd wait for the results to see whether it's worth it or whether you should just wait for Zen4.

So far it's only been tested on AMD cards, which have slower memory and a smaller interface (compared to the 3080 and 3090) - will be interesting to see whether there is any difference.

300 series motherboards. 3000 series processors support RBAR don't they?

I know what you mean now, I have a B450 so that would be a 400 series. Aretak has addressed it perfectly above. I think all the Zen processors can use it, however will have to test for some time after to see if it nets any % increases.

Will be interesting how much of a difference the 3090's 24gb VRAM makes. Would be nice to have something use the other half of the VRAM I'm not currently using.

you mean the bioses..

Do we expect Nvidia to add the mining nerf to newer BIOSes?

Doubt it, but you can always save the old and reflash it if the hash gets toasted with the new bios.

So no performance increase for nvidia so far with it enabled, guess amd put in more work than just flipping a switch

Just heard back from Palit that they will be rolling out the new vbios for their 3000 series lineup within the next few weeks! They've included an easy to use bios updater as well to flash the new bios onto it. I have to admit im a little skeptical about using it, don't have a backup bios incase it gets borked in the unlikely event of something going wrong.

So close now, really hope the 3090 has more to offer with its extra vram!

So with my setup I would need a Zen 3 CPU, flash my motherboard BIOS, flash my 3070 FE BIOS? I'm not planning to upgrade for a while but its a nice option. Currently I'm thinking I'll just stay with my 3600 until there is a game that needs 8C/16T, then get resize bar, PCIe4, new AMD socket, ITX motherboard with 2 NVMe sockets.

Nvidia are updating the BIOS of all their Ampere GPUs to support it, we don't have the updates yet.

AMD already have it supported on Big Navi

Is the new BIOS out yet?

Nvidia have some severe framepacing issues to fix with ReBar on, at least in Borderlands 3. AMD generally get better, sometimes significantly better, frametimes with SAM on: https://www.igorslab.de/en/resizeab...amd-radeon-and-nvidia-geforce-in-benchmark/5/

I'll wait to update my 3080's VBIOS until such issues are fixed.

It was always the case otherwise we wouldn't have to wait so long for Nvidia to catch up. Only fanboys were trying to argue to the contrary.

It's coming to Ryzen 3000 too: https://www.techpowerup.com/279264/...ry-resizable-bar-support-to-ryzen-3000-series

It's enabled on the laptops I thought, I watched a Linus video and it did sweet f.a, and it needs more work

 

[Lightnix]

It's on the 3060 already. Gets some reasonable bumps in some games, not so much in others: https://www.eurogamer.net/articles/digitalfoundry-2021-nvidia-geforce-rtx-3060-review?page=6

Oh nice thanks. AMD CPUs are the gift thats keeps giving

 

[VincentHanna]

Doesn't it stand to reason that the gains on more powerful cards should be even more substantial?

 

[robfosters]

Is it just as dangerous to update your Vbios as it is your bios?

Back in 2004 yes, now not so much
