Intel’s Arc 7 graphics cards have been a very long time coming. In reality, the wait stretched so lengthy that pleasure largely fizzled about Team Blue taking up Nvidia and AMD. Gamers needed a rescue from pandemic shortages and inflated pricing, and received none.
But higher late than by no means—particularly when Intel’s Arc A770 and A750 playing cards can pull out some spectacular efficiency. Intel’s first era of discrete GPUs characterize enormous potential for a wholesome aggressive setting, with three gamers within the ring all vying for the title of greatest at school.
The downside is, Arc is first-gen expertise, and it’s received teething pains to get via nonetheless. If you occur to play the correct of video games, the Intel Arc A770 (accessible in $349 16GB and $329 8GB flavors) or $289 Intel Arc A750 may give you the results you want. But if not, you must wait, or decide up a unique card all collectively.
Our comprehensive Arc A770 and A750 review covers the complete particulars, however right here’s the fundamentals of what to anticipate when these playing cards arrive on October 12th.
Only trendy PCs want apply

Was your CPU manufactured earlier than 2019? If you personal one thing older than an AMD Ryzen 3000 (2019) or Intel 10th-generation Comet Lake (2020) processor, you’ll doubtless desire a graphics card from a competing vendor.
The cause: Intel’s Arc playing cards lean closely on a function known as resizable BAR, which is barely accessible in trendy processors. In reality, they solely shipped as an out-of-the-box function for Ryzen 5000 and 12th-generation Intel chips. You should carry out a motherboard BIOS replace earlier than enabling it for older appropriate chips.
Resizable BAR (additionally affectionately often called ReBAR) lets your CPU entry your entire GPU’s reminiscence framebuffer without delay, relatively than in 256MB chunks. On Nvidia GeForce and AMD Radeon graphics playing cards, flipping on ReBAR reasonably boosts efficiency. But Arc’s reminiscence controller design depends on ReBAR rather more closely, with extra notable impression on body charges in video games and smoothness of gameplay when it’s off or unavailable. In 5 of our benchmarks, the distinction between ReBAR on and off in DirectX 12 efficiency begins at 14 p.c, with as a lot as a 38 p.c hole.
Essentially, when you’ve got an older PC and have been ready for a extra inexpensive graphics card to increase its life additional, Arc isn’t it. You’re higher off with an Nvidia or AMD possibility.
Performance rocks on trendy APIs
Intel Arc 7 GPUs actually love modernity—not simply {hardware}, however APIs like DirectX12 and Vulkan, too. The top-tier Arc A770 can completely smash the competitors in optimized video games working these trendy graphics APIs. In titles like Metro Exodus and Borderlands 3, Arc gives a important efficiency uplift in comparison with the Nvidia GeForce RTX 3060 and AMD Radeon RX 6600, each at 1080p and 1440p.

It’s not all wins for the Arc playing cards, nonetheless. Driver optimization continues to be a piece in progress, and so AMD and Nvidia take a transparent lead in some video games, like in Cyberpunk 2077 and F1 2020 at 1080p. But dive into the numbers, and also you’ll see it’s not a real loss—players nonetheless get close to 60fps in Cyberpunk 2077 with all of the ray-traced bells and whistles turned on. In different video games, body charges are effectively above that.

But nosedives in DirectX 11 generally
Arc shines in trendy video games with DirectX 12 and Vulkan help, however there’s one downside: Plenty of video games nonetheless use DirectX 11. Think indie video games, and even AA tasks (titles with tangible funding and sources, however not the massive blockbusters). Many folks even have an enormous backlog of older video games to get via, and people depend on equally older APIs, like DirectX 9.
Brad Chacos/IDG
Take for instance Shadow of the Tomb Raider. Using DX12, the sport’s really useful API, each the Arc A770 and A750 simply hold tempo with the competitors. (Though the $350 16GB A770 is the place Intel shines—it holds its personal in opposition to the dearer RTX 3060, whereas the A750 cedes some floor to its cheaper RX 6600 rival.)
But flip the swap to DX11, and the A770’s efficiency plummets. With resizable BAR left on, it runs 49 p.c slower. Turn off reBAR, and it plunges all the way down to 55 p.c. The different video games in our benchmark suite present efficiency losses between 25 and 50 p.c with reBAR on in DX11 mode, and 29 to 51 p.c with reBAR off. Ouch.
(The one oddball exception: F1 2020, the place A770 will get a enhance in efficiency when switching over to DX11 and turning reBAR off.)
Beats Nvidia’s RTX 30-series playing cards in ray-tracing
Hang on to your security bar—this rollercoaster is about to hit one other exhilarating loop-de-loop.
Nvidia has lengthy held the crown for ray-tracing efficiency. It arrived first to the social gathering, after which launched its Deep Learning Super Sampling (DLSS) tech to additional enhance efficiency by rendering frames at a decrease decision after which upscaling them.
But now that Intel has appeared on scene, Nvidia can now not declare the highest spot universally. The A770 beat the RTX 3060 in uncooked ray tracing efficiency (with out upscaling options like DLSS or Intel’s XeSS energetic) in three of the 4 video games we examined. The A770 (and A750) trounced AMD’s Radeon RX 6600, too.
Brad Chacos/IDG
The catch: DLSS is way extra developed, with extra illustration in video games. In the true world, meaning Nvidia can present increased body charges. Intel does have an equal expertise for its playing cards, XeSS, however sport help will take time. DLSS is at the moment in a whole bunch of video games, whereas XeSS is barely in a handful.
Still, by way of uncooked efficiency, Intel ought to have the ability to cling onto this accolade for a bit. Nvidia’s upcoming launch of RTX 40-series of playing cards will initially deal with high-end, flagship playing cards—far above the A770 and RTX 3060’s value tier. An RTX 4060 (with presumably higher ray-tracing efficiency) isn’t more likely to launch till subsequent yr.
High energy consumption, particularly at idle
Brad Chacos/IDG
In the US, energy draw didn’t use to be as a lot of a dialog. It was extra of a factor checked for mental curiosity. But now with rising power prices worldwide, the deal with {hardware} electrical energy use is rising. (For instance, our recent review of AMD’s Ryzen 7000 CPUs addresses this similar challenge.)
Unfortunately Intel Arc 7 playing cards devour extra energy than their Nvidia and AMD counterparts, each below load and at idle. In reality, the idle energy use is startling—in our measurements of entire system energy draw, our Arc machines used almost double that of rivals. Even below load, you’re taking a look at about 50 p.c extra use than the RX 6600. (The A770 not less than affords increased efficiency, although.)
This information isn’t an entire shock, provided that the RTX 3060 and RX 6600 use single 8-pin connectors, whereas Arc makes use of 8-pin + 6-pin. But in case your electrical energy charges have gone up, this may very well be one other level of main consideration.
Better wanting, decrease bandwidth encodes
Adam Taylor/IDG
Right now, Intel is the one firm that helps AV1 encoding—a type of encoding that improves the picture high quality whereas additionally lowering bandwidth wanted to view the video. That’s an enormous boon for streaming and seize uploads, and as our Arc AV1 testing shows, Intel’s outcomes look extremely promising.
However, don’t run out to seize an Arc 7 card simply for this profit. All Arc playing cards help this encoding function, together with the Arc A770 and A750’s much-cheaper sibling, the $140 Arc A380. Pick up an Arc 7 card if you need the stellar trendy AAA gaming efficiency and AV1 encode help as effectively. Otherwise, in case your solely purpose is to supercharge your seize/streaming PC, it can save you some money.
Driver help is a work-in-progress
Thiago Trevisan/IDG
When Intel’s low-end Arc A380 launched in China earlier this yr, driver points plagued the {hardware}. The state of affairs has enormously improved since then, however Intel’s latest Arc GPUs nonetheless undergo from glitches at launch.
If you purchase one in all these playing cards, hold a reserve of persistence readily available. During our testing, our benchmark machine locked up a number of occasions—nothing recurring or showstopping, simply irritating. Windows additionally required permissions approval for Intel’s Arc Control app upon every reboot.
That mentioned, Intel additionally mounted a lot of points simply in the course of the evaluate interval: video games that did not launch all collectively, app crashes when utilizing a sure API mode or options like ray-tracing, and sport corruption.
Nvidia and AMD have a lot headway on this entrance, with AMD particularly having largely rotated public notion of its drivers. Intel nonetheless has a bumpy trip forward, as famous in our full Arc A770 and A750 review—so it’s important to resolve when you’re prepared to take that bone-rattling in alternate for an inexpensive graphics card.
