Intel’s first Arc GPUs have finally arrived — here’s what you need to know

Easy Page Buildr

Not to be melodramatic, today might be one of the most important days in PC gaming history. Intel is launching its first batch of Arc GPUs today, adding a third major competitor to a market that’s been dominated by Nvidia and AMD (or ATI, back in the day) for as long as many gamers and creators can remember.

Now the question is just whether Intel’s discrete GPUs are any good.

I’ll go ahead and warn you right away that Intel didn’t provide any hard comparisons with its competitors; we’ll have to wait for real-world benchmarks for those. Still, there’s a lot to unpack here. The technically inclined can go read Intel’s official announcementbut we’ve summed up the main things you should know.

So can I go buy an Intel GPU and stick it into my desktop now?

Not quite yet. Intel is rolling out its Arc family of GPUs slowly, starting with entry-level units designed for mainstream laptops.

So far, Intel is dividing its GPUs into three tiers: Arc 3, Arc 5, and Arc 7. Arc 3 is aimed at thin-and-light laptops and is focused on providing a solid 1080p experience, while Arc 5 and Arc 7 target higher resolutions, framerates, and effects.

Only Arc 3 chips are available starting today, with devices coming from Samsung, Asus, Dell, Lenovo, HP, Acer, and more. The first Arc 3 models are divided into Arc 350M and Arc 370M variants, with the latter being more powerful.

Laptops powered by Arc 5 and Arc 7 will begin to show up in the “early summer,” while desktop and workstation GPUs arrive “this summer.” Signs.

What do Intel’s Arc chips do differently from AMD and Nvidia?

The most notable technology on offer might be what Intel is calling its ‘Xe Matrix Extentions’ (XMX) AI engines, which live alongside traditional GPU vector engines in each of Intel’s Xe graphics cores. Intel claims that its XMX engines “provide a 16x increase in compute capability to complete AI inferencing operations compared with traditional GPU vector units.”

That’s a bit of gobbledygook, but it basically means that Intel’s XMX tech should be a lot more efficient at solving AI operations than typical GPUs, assuming optimal implementation.

How much of an improvement that translates to in the real world remains to be seen, but Intel is making a big deal of Arc’s ability to combine traditional graphics performance with AI enhancement.

To that effect, Arc GPUs will support Intel’s take on AI-based upscaling called XeSS. Like Nvidia’s DLSS and AMD’s FSR, XeSS would allow your GPU to render graphics at a lower resolution — say 1080P — but output a result that looks a lot closer to native 4K.

Unsurprisingly, Intel implies that because its XMX cores are so efficient, its version of AI upscaling is more efficient than the competition’s, but we’ll have to wait for some direct comparisons to see if that holds up.

But the neat thing about XeSS is that it doesn’t only work with Intel’s GPUs. Although it is most efficient with XMX, it can actually work with many current competing GPUs from AMD and Nvidia, as well as Intel’s less powerful Iris graphics, by leveraging the older DP4a technology.

Unfortunately, also like DLSS, it does require game developers to get on board to support the technology. Intel says there will be more than 20 games that support the technology when XeSS becomes available this summer.

What else can Arc do?

AI enhancements aside, Intel says its Deep Link technology will allow Arc GPUs to work more seamlessly with its CPUs and integrated graphics to enable significant performance gains across various workloads:

  • ‘Dynamic Power Share’ can boost performance by up to 30% boost in intensive workloads by rapidly adjusting the power consumption of each processor based on an application’s needs.
  • ‘Hyper Encode’ can shorten render time by up to 60% “compared to Iris Xe graphics alone” by leveraging the media engines from both your integrated graphics and your dedicated graphics.
  • ‘Hyper Compute’ offers up to 24% higher performance in “a variety of new workloads” by combining the compute and AI capabilities of the CPU, integrated Iris graphics, and dedicated Arc graphics all at once.

Other features include:

  • Supper for DirectX 12 Ultimate, including ray tracing, variable-rate shading, mesh shading, and sampler feedback.
  • Hardware-accelerated AV1 encoding and decoding.
  • Adaptive Sync and Speed ​​Sync help eliminate tearing while maintaining low latency.
  • Smooth Sync helps minimize tearing by essentially, making it look less janky.
  • Support for two 8K displays at 60 Hz, or four 4K displays at 120Hz.
  • Intel’s Arc Control App mimics Nvidia’s GeForce Experience and AMD’s Radeon Software as an all-in-one hub for viewing the latest drivers and adjusting settings.

Okay, but do we have any idea how it compares to Nvidia and AMD GPUs?

Unfortunately, it’s just too early to tell. Intel’s Arc briefing didn’t include direct comparisons with its competitors, only to the company’s own Iris Xe integrated graphics. It shows significant improvements, as you can see in the chart below, but that’s obviously expected when you go from integrated graphics to a dedicated chipset.

Based on the targeted power consumption and execution units, the Arc 350M seems to be competitive with GPUs like Nvidia’s MX500 series, while the Arc 370M seems might be competitive with a mobile RTX 3050. But again, the proof is in the pudding. Intel’s XeSS and Deep Link technologies may help give it an edge in some situations, while lack of optimization could give Nvidia the lead in others.

What does this mean for the tech industry?

Regardless, the most exciting thing about this launch is the fact that we have any real competition to Nvidia and AMD at all, let alone from such a major player. It’s particularly important for laptops, where Intel has the distinct advantage of (theoretically) being able to make its CPU, integrated GPU, and external GPU coexist as efficiently as possible while minimizing power consumption.

While many of us are still eagerly awaiting what Intel will do in the desktop graphics market, it’s likely Intel’s play for the mobile market will be of wider consequence.

There’s a very real possibility that Arc could lead to the wider proliferation of dedicated graphics in lighter and more affordable laptops, especially as competition leads to better performance.

The most impressive thing about Intel’s Arc launch may be how many manufacturers have already signed up to take advantage of the new graphics chipset, especially in this performance category. While gaming laptops with powerful GPUs are a dime a dozen, there’s traditionally been a massive performance gap between mainstream lightweight laptops and those gaming models.

AMD has tried to fill some of that gap, but Intel’s market dominance will likely help the company push for more devices with Arc graphics. The first Arc-enabled devices will start at $899, suggesting discrete graphics in laptops are about to become a good deal more common.

One thing’s for sure: the GPU industry has never been so exciting.
