Resizable Bar
Do everyone use it to boost performance ? or is its just a gimmick ?

will it increase my system performance ?
cpu - ryzen 5600g
motherboard- b450
pcie - 3.0
gpu - rx 9060xt 16gb




edit:

Well , I've tested for a long time now by turning re-bar on and off from bios and playing different games .....and I can confirm that it increases fps significantly in gpu heavy single player games , like horizon zero dawn , ghost of tushima , avatar frontiers of pandora , etc. Fps increased over 20 in some games....
but will massively degrade the performance of cpu dependent games if u got a weaker cpu that is already kinda struggling ....games like delta force , space Marine 2 , warhammer darktide were total stuttery mess with bad frametime graph and a overall a very bad experience with it turned on , and turning it off improved performance massively in those games ...now gpu usage always stays above 95, and rarely drops ... earlier it was never above 80...

So yeah it's not for weaker CPU's , and specially if the cpu is already struggling it will make it worse.

seem to help in newer games on my end....things like BF2042 and death stranding seem like they have a lot less stuttering with it on.....

I have it on by default.
I’ve seen few benchmarks and it seems to have a positive impact on average but it depends on a game.

i feel like im having low fps / stuttering in darktide with it on .. though not sure .. is my 5600g too weak for rx 9060xt on dakrtide 1080p max settings ?
all other games seems fine

5600G might be better without this but I'm not 100% sure.

If a game is unpoptimised it can sometimes run worse.

As for stuttering, never heard of that game, but keep in mind that a 5600G is not the same as a 5600X -- it has less cache, and that lack of cache can make a difference depending on how the game is coded.

When and where it will make a difference, no one really knows because no one is all-knowing, but you can bet it will make a difference the less optimised a game is.
Ok I hope you know tbat whenever you have a Ryzen G model APU installed it forces the PCIE X16 slot into X8 mode. So you are hurting your dedicated GPU no matter what you do.

Best bet is find another use for that 5600G or sell it a d get a 5600X or 5700X3D

That might impact me if I ran out of vram on my Rx 9060 xt ....which is unlikely for now atleast since it's 16gb

But I have plans to upgrade to a 5.0 system with Ryzen 5 9600x

That has nothing to do with the amount of VRAM on your card, it reduces the total amount of bandwidth your card can send over PCI-E.

Yes , but if u compare performance of a gpu running on various generations of pcie the you will see the difference is very minimal ..most likely 2-3 fps difference at maximum. This happens only if the vram is sufficient.

The problem arises when the gpu runs of vram and needs to use the pcie bandwidth to communicate with RAM ..at that point the difference is very massive ..likely over a 100% of performance boost when going up a pcie generation

would get a 9700x over the 9600x....its worth it to have 8 cores now......over the current CPU it would be a MASSIVE upgrade.....

the price difference is significant , almost double the price when comparing 9600x and 9700x

the 5600G only has PCIe 3 x16 which severly limits the bandwidth of your 9060 XT (btw you made the right choice getting the 16GB version)

so yeah get at least 5600X or even better then 5700X3D/5800X3D then you'll be running on PCIe 4.0


I'm surprised that nobody has mentioned the PCIe interface because AMD is scummy enough to give their APUs older pcie 3.0 instead of 4.0


edit: also check if your motherboard supports pcie 4.0 not sure if any of the B450 mobos run on 4.0

i know :( , the b450 only supports upto 3.0 pcie , so for 4.0 or higher i need a mobo upgrade and the cpu also is 3.0 only so i need a complete system upgrade since RAM is also 3000mhz , and probably i need higher psu than a 550w(currently ) for all these .. so a completely new system :(
I have a b450, ryzen 5600gt and it only supports 3.0

It does register all 16 lanes though. But I tried putting 3700x, 5600, 5700x3d and it's still 3.0 PCI no matter what.
