Short answer: Intel’s Arc A770 Limited Edition is the more convincing ray-tracing card, while the A750 is best treated as a 1080p RT GPU. Native 1440p ultra ray tracing is generally too demanding for both; the A770 can handle selected 1440p settings, especially with XeSS, but neither card delivers consistently smooth performance in every game. Their 16GB/8GB memory capacities and modern media features are strong, yet API-dependent performance and immature support for some older games remain important trade-offs.
What the A770 Limited Edition and A750 Limited Edition are
The A770 Limited Edition is Intel’s higher-tier Alchemist card. The A750 uses the same 225W total board power rating but has fewer Xe cores, fewer ray-tracing units and half the memory. The core hardware is summarized below.
| Specification | Arc A770 Limited Edition | Arc A750 Limited Edition |
|---|---|---|
| Xe cores/XMX engines | 32 | 28 |
| Ray-tracing units | 32 | 28 |
| Memory | 16GB GDDR6 at 17.5Gbps | 8GB GDDR6 at 16Gbps |
| Memory bandwidth | 560GB/s | 512GB/s |
| PCIe interface | PCIe 4.0 x16 | Not stated in the cited specification summary |
| Total board power | 225W | 225W |
The A770 Limited Edition also provides hardware acceleration for AV1, HEVC, H.264 and VP9, three DisplayPort 2.0 outputs and HDMI 2.1. Those capabilities make it more than a conventional rasterization upgrade, particularly for video encoding and high-resolution display setups.
How good is the Arc A770 at ray tracing?
1080p: the most practical target
At 1080p, the A770 has enough ray-tracing throughput for a usable experience in supported games, provided settings are chosen sensibly. Performance still depends heavily on the title and graphics preset, so “ray tracing on” should not be interpreted as a guaranteed ultra-quality result.

1440p: selective settings, not native ultra
Tom’s Hardware found that 1440p ultra DXR was beyond what the A770 could comfortably manage with native rendering. In that test configuration, the card essentially matched an RTX 2080 Super while costing about half as much at the time of testing and offering twice the VRAM. That is a favorable value result, but it does not make native 1440p ultra ray tracing a practical default.
For 1440p, the realistic approach is to reduce demanding effects, use a sensible quality preset and enable XeSS when the game supports it. The A770’s larger memory pool gives it more room for high-resolution textures and RT data than the A750, but memory capacity cannot compensate for insufficient shader or RT performance.
Can the Arc A750 run ray tracing at 1440p?
1080p results vary from good to unusable
Tom’s Hardware measured a 62-fps average across five games at 1080p medium ray tracing. That aggregate was pulled upward by Metro Exodus at 112 fps and Control at 81 fps. The same review recorded less than 30 fps in Cyberpunk 2077 and only 18 fps in Bright Memory Infinite with the game’s maxed 1080p RT settings.
The spread matters more than the average: the A750 can look competent in a well-optimized RT implementation, then fall below a comfortable frame rate when effects are unusually heavy or the game’s rendering path is less favorable.
1440p max RT is a narrow use case
At 1440p maximum RT settings, the A750 was only barely viable in Control and Metro Exodus. That result was better than the RTX 3050 or Radeon RX 6650 XT at those settings in the cited comparison, although those two cards were not tested at the same 1440p max-RT settings. For most A750 owners, 1440p RT should therefore mean reduced settings and, where available, an upscaler rather than native maximum quality.
Native rendering versus XeSS
XeSS can recover a substantial amount of performance by rendering internally at a lower resolution and reconstructing the image. It is especially useful when ray tracing pushes a scene below the desired frame rate. However, game support was limited when these tests were conducted, so XeSS could not be treated as a universal solution. A game without XeSS leaves you dependent on native rendering or whatever alternative scaling mode it provides.
The practical hierarchy is straightforward:
- Native 1080p: the safest choice for image quality, with RT settings adjusted to the game.
- Native 1440p: suitable for lighter RT workloads or reduced presets, especially on the A770.
- 1440p with XeSS: the most credible way to pursue RT on the A770 when the title supports it.
- A750 at 1440p: use lower RT settings and an upscaler; maximum native RT is generally too demanding.
Arc performance depends strongly on the game and API
TechSpot’s 12-game testing showed large swings rather than a consistent ranking. Arc cards performed well in some DirectX 12 and Vulkan games, while results were weak in Horizon Zero Dawn, Halo Infinite and especially the older DirectX 9 version of Counter-Strike: Global Offensive.

- HDMI, and DisplayPort, this GPU is ready to connect to the latest displays, including 4K monitors.
- Immersive Visuals: Unlock stunning visuals and seamless gameplay with the Intel Arc A770 Photon, designed to handle demanding graphics workloads with ease.
This means the A770 or A750 cannot be judged from one benchmark or from specifications alone. Newer DX12/Vulkan titles with good Arc optimization are the cards’ strongest environment. Older games and poorly optimized rendering paths are where driver and compatibility risk becomes most visible.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Power, cooling and board features
Both Limited Edition boards carry a 225W total board power rating. In TechSpot’s comparison, the A770 consumed 23% more power than the Radeon 6650 XT. That additional consumption should be included in a system’s power-supply and case-airflow planning.
PC Gamer described the A770 Limited Edition as relatively quiet and cool, including being surprisingly quiet under full load. The same source lists its modern display outputs and media acceleration, including AV1 encoding support. Those are meaningful advantages for creators and streamers even when game performance is inconsistent.
Launch pricing and value
Intel announced launch starting prices of $289 for the A750, $329 for the standard A770 and $349 for the A770 Limited Edition. These were launch figures, not a guarantee of later retail pricing. The cited reviews do not establish a current street price, so any buying decision should use a live listing and account for stock, seller and regional pricing.

TechSpot’s conclusion was that Arc pricing needed to be substantially lower to offset the software risk. The A770’s 16GB memory and capable RT hardware can make it attractive when discounted, while the A750’s value depends even more on a favorable price because its 8GB buffer leaves less headroom for demanding 1440p textures and RT workloads.
Which card fits which buyer?
Choose the A770 Limited Edition when
- You want the stronger of the two Arc cards for ray tracing.
- You play modern DX12 or Vulkan titles and can use XeSS where supported.
- You need 16GB of VRAM for high-resolution textures, mods or longer-term headroom.
- AV1 encoding, HDMI 2.1 or DisplayPort 2.0 are useful to your setup.
Choose the A750 Limited Edition when
- Your target is primarily 1080p gaming with selective ray tracing.
- You accept reducing RT quality or using an upscaler at 1440p.
- The A750 is meaningfully cheaper than the A770 in your market.
- You mainly play titles known to perform well on modern DX12 or Vulkan paths.
Consider another GPU when
- Your library is dominated by older DirectX 9 games or titles with known Arc performance problems.
- You require predictable native 1440p ultra ray tracing.
- Power efficiency is a higher priority than Arc’s media and memory features.
Verdict
Alchemist delivers a surprisingly capable ray-tracing foundation, particularly on the A770 Limited Edition. The A750 can produce good 1080p RT results but has a much narrower margin at 1440p. XeSS can transform borderline performance when available, yet limited game support and large API-to-API swings prevent either card from being a universally safe recommendation. Buy at a price that compensates for that software uncertainty, and match the card to a modern, well-optimized game library.
