Intel Lists Resizable BAR Support as an Arc GPU Requirement for Optimal Performance

Intel has recently published a document outlining the requirements for Arc GPU support on desktop including the supported platforms. The guide states that supported processors are limited to 12th Gen Core "Alder Lake", 11th Gen Core "Rocket Lake", and 10th Gen Core "Comet Lake" with Resizable BAR support enabled on the motherboard. The document also notes that other platforms supporting Resizable BAR / Smart Access Memory may work with Intel Arc graphics cards indicating potential unofficial support for AMD platforms also. Intel has also specified that only Windows 10/11 is supported and installations must be using the GPT partition type. The page contains instructions to enable Resizable BAR support and switch to a GPT partition but no information is provided as to whether the cards will work without this functionality.

Yet nGreedia still won't bring a simple BIOS update out for the still manufactured RTX20x0 series.

Last time I turned on resizable bar on my current gaming rig (i7-11700k) it did not work at all. Although this is with an AMD gpu, ever since then it's been disabled. Suppose I should give it a try again, perhaps with the newer drivers from AMD it might work again. There is an option in radeon software suite to enable it.

Hi,
GPT only reason I can see is it wants to create yet another partition
Optimum performance okay I'll pass and just keep simple performance :laugh:

Why would Arc only work with the latest 3 Intel CPU generations? Also, what's with the GPT partitioning? These are some very weird limitations that aren't very good for business (why won't it work on AMD?).

At this rate, I wouldn't be surprised if the next news article said that Arc GPUs will be made for OEMs and only by Asus, like the mysterious DG1.

Feels like BS similar to Windows 11 requirements. They won't win on this.

For optimal performance we first need the GPU.

Hi,
Yeah optimal performance is just blah blah blah

If anyone want "best performance" use a performance power plan "11 hides this" and find a happy medium all core oc
Gpu wise use core curve for a steady core clock so the core clock doesn't bounce all over the place and cause issues.

Who the hell are you people not using GPT for your installations? My desktop is a 10+ year old Haswell machine and it's had a GPT install since day 1.

One of the reasons I was understanding Intel's need to get back to GPUs, was the probability of AMD and Nvidia making their GPUs incompatible with Intel's platform. Nvidia could build it's own ARM based platforms for gamers, AMD of course already has it. That could totally destroy Intel in the desktop/laptop market.
Now Intel's first series of GPUs is probably incompatible with a number of platforms.

Probably for compatability with direct storage as well.

Hi,
Main reason is 4 partitions is 2 more than I need which is a system reserved and C, boom done.
Not to mention I don't have any hdd/ ssd's over 2 tb so gpt is not need on them.

Even hdd/ ssd manufactures don't format drives gpt so ask them why :laugh:

11 requires a lot of silly new security stuff and all of that can be leapfrogged over, I should know I've done it on all my systems even the ones that can be compliant.

As far as resizable bar goes none of my current gpu's can use it anyway.

What does GPT have to do with this?

Hi,
It's a requirement to use resizable bar.

Well they sent them to china so they must smell of raja's stench

There are other stuff to turn on too, like CSM, secureboot, above 4g decoding etc. I forgot what exactly, but im pretty sure it wasnt 1 setting.

UEFI only with no legacy support is my guess

Anything they can do to save time and effort is critical, since they're playing catchup

Everyone running on older hardware (LOL, even older Intel hardware) won't be buying an Arc GPU. I wouldn't guess this is a good idea considering intel:
1. won't be competing with AMD or Nvidia at all in the enthusiast videocard market segment
2. will probably be barely competing with AMD and Nvidia in the mid-range market segment (once the next-gen AMD and Nvidia GPU's are out).

Even my Kaby Lake system had UEFI. New AMD systems surely do as well.

That stuff you mention was already turned on in bios settings, but like I said before, still haven't booted up & tried again on that rig with the latest 22.5.2 radeon drivers.

Of course - but UEFI requires GPT.

If they've decided to ditch legacy support with their VBIOS, it explains the requirement

Resizable bar works with pcie 3.0 on Intel gpus, but nvidia says only on pcie 4.0 on their rtx 30 series. Maybe nvidia wants more profits from us cause if it works on pcie3.0 for Intel it surely works in nvidia.

It is just nGreedia being nGreedia. It's in the game. Or is it For the gamers now...?

Nvidia sticking to a PCIe 4.0 standard doesn't help them or hinder them because I thought they were out of the motherboard chipset business?

Enjoy your shitty corrupted disks since MBR stores boot and partition data in one place and has no CRC value capability. Absolutely insane reasoning to still be using MBR over GPT. Not a single drive manufacturer still recommends MBR.

Hi,
Seeing I've never had any corrupt "disks" on 5 systems with dozens of ssd's and hdd's in use I doubt you state is anywhere near accurate :laugh:
