If you own an old CPU, don't buy an Intel ARC A-series GPU
You must have a relatively new system to get the most out of Intel's latest GPUs

Resizable BAR is a must-have feature for Intel's ARC A-series graphics cards
Intel's ARC A-series of graphics cards is about to launch, adding a third player into the gaming GPU market and strong mid-range offerings in the form of Intel's ARC A770 and ARC A750. Today, Intel has confirmed the hardware requirements of their ARC A-series, confirming that Resizable BAR support is a must-have feature for those who want optimal performance from their ARC A-series graphics cards.
With their Radeon RX 6000 series, AMD utilises Resizable BAR to deliver increased GPU performance through a feature called "Smart Access Memory". With their ARC A-series of graphics cards, Intel has designed their graphics cards with Resizable BAR as a baseline feature, which means that their graphics cards will not perform optimally with systems that lack support for Resizable BAR.
You will need a relatively new CPU to get the most from Intel's ARC A-series
In the chart below, Intel has recommended that PC gamers have a system with an Intel 10th generation Core processor or a Ryzen 3000 series (Zen 2) processor or newer with a motherboard that supports Resizable BAR/Smart Access Memory. Intel's GPUs are not designed for older systems that lack support for Resizable BAR, which means that ARC A-series buyers will need a relatively new system to access the peak performance levels of Intel's ARC Alchemist GPU architecture.
The good news for some owners of older systems is that many older motherboards have BIOS updates that enable support for Resizable BAR. That said, support for this feature is not guaranteed for systems that do not meet the hardware requirements that are listed on the chart below.
Intel's new ARC A-series of graphics cards have also been designed with Windows 10 20H2 and Windows 11 systems. This means that Intel's ARC A-series graphics cards will not work with older versions of Windows. Simply put, Intel are not making GPU drivers for Windows 7 (why would they?).
While Intel does plan to optimise their ARC A-series of graphics cards to work better without Resizable BAR in the future, the company are unlikely to drop the feature as a hardware requirement.
Intel plans to launch their ARC A-series of graphics cards on October 12th.
