Has anyone here compared RTX4060 to B580 on a low-end CPU & disabled REBAR?

Because budget systems would have these combos. If anyone tried this, is the experience better on RTX4060 or B580?

Can Intel solve this issue? What will Nvidia do if yes?

Low end CPUs are already no no for B580. And without rebar it basically becomes unusable.
Hopefully, Intel can fix this driver overhead issue. They should be able to, it's a software problem.
For rebar, I don't think they'd bother. Even budget systems should have that anyway. Only for low end systems it's a problem but you wouldnt really use capable gpu with those anyway.
And Nvidia doesn't care about competition anymore. Especially on discrete gpus for gaming. It's not that big of a income source for them anymore. Well, Intel is years behind eitherway.

Do players need to fiddle with settings to enable rebar on windows 11? Windows 11 is known for unwanted default settings here and there.

No, ReBAR is enabled in BIOS. Both Windows 10 and 11 behave identically in this regard and you don't need to enable anything inside your OS.

I disagree.

That option is well hidden in the mainboard firmware. It is also named differently as RBAR. It was for a long time deaktiviated with every new mainboard firmware. I usually update the mainboard at least 5 times a year. That is without changing the firmware when ASUS get the stuff wrong or MSI has performance issues or other issues.

You better check if RBAR is activated after each firmware change.

When nvidia enables gpu-decompression, it will take some load from cpu, but how much?

I am not sure what you mean here. Do you mean nvCOMP? Because any other feature is architecture-dependent and either works or not, so it’s already factored into current performance numbers.

Can Intel solve this issue?
It isn’t an “issue”. The architecture is explicitly designed so as to require ReBAR. There’s nothing to solve.

Yes I meant nvidia working with game makers to use nvComp.

It isn’t really meant for that and as long as games are developed primarily for Radeon powered consoles it won’t become a thing.

Nvidia uses a software scheduler that really handles requests from the CPU, which is why its performance degrades in 100% bound scenarios.
The information I can find on Intel Arc is that they also use a software scheduler, so that can probably improve it in some scenarios, but not everywhere.

Only Radeon had a hardware scheduler and in CPU bound scenarios they performed better.
And this information is ancient, that AMD Radeon works better on weak systems, so the videos popping up everywhere don't show anything new.

Did you actually read what I wrote? I said it's enabled in BIOS which is precisely what lets you tune the firmware settings. You just proved my point.

99 percent they can.
It could be a feature within the architecture, like Alchemist not having DX11 and earlier support, only a translation layer in the driver. Speaking of which... how is this situation on Battlemage?

cpu's are cheap these days, there is no need to do something like this, even the hardcore old school "i will spend 90% of the money on the gpu" wouldn't do this, internet also helps avoid these mistakes. I guess if someone is doing this is prebuilds maybe
There is just no need.

Though it does negate the usefulness of the card as a pop-in upgrade for an old PC.

if you scavenge the money for a 4060 (they are not cheap), i'm sure you can buy a reasonable cpu, and those are really cheap in comparison.
If you're stuck in a very old potato, dell optiplex, idk, it's the same complaint i have again, why spend so much on the gpu and so little on the rest. Buy a lower tier gpu and upgrade the rest. Ferrari with bald tires

I wouldn't recommend a rtx 4060 gpu if you dont have a pcie 4.0 mb.

Not necessarily. You shouldn't assume other people's financial situation. And a 4060, as expensive as it is ($300 is a lot for some), is still the bottom of what you can buy these days, unfortunately.

I would love to put a low-profile 4060 into my i7-4765T HTPC if I had spare 300 quid to throw away. Upgrading the whole system is completely unnecessary, though (it's a HTPC).

I don't necessarily think it's just the CPU speed / core count being the problem on its own.

The requirement for ReBAR also implies that the card utilises / needs data transfers in larger allocated blocks for better performance - I do wonder if the improved IO of the newest platforms also impacts performance vs CPU speed.

Testing utilising slower RAM or slower IF speeds and measuring how much of an impact that has vs other GPUs would also show where the limitations are. Imagine some users upgrade from say a Zen+ CPU to a Zen3 and keep same RAM - sure they're giving away some game performance but what if it snowballs in that scenario.

To be fair, assuming it is just HTPC use and you're not expecting much work in terms of transcoding, the cheapest Intel or AMD GPUs would work fine - think even Intel's worst A3xx Arc cards do AV1 decode also.
