Both Intel Arc A770 and A750 will be launched on 10/12. In addition to Intel’s limited edition, there should also be brands launching self-made card products. As for whether the Arc performance is sufficient, and whether one card can meet the needs of games such as e-sports, AAA, and light pursuit, let us first understand the characteristics and key points of the Xe HPG micro-architecture.

Xe HPG micro-architecture is full of next-generation technologies

The Intel Xe HPG micro-architecture, codenamed Alchemist, has the ray tracing and XeSS AI acceleration technology required by the new generation of GPUs, and more fully supports DirectX 12 Ultimate and Vulkan’s contemporary mainstream Low-Level API, allowing game developers and game engines to More efficient use of GPU resources.

At the same time, it provides HDMI 2.1 and DP 2.0 output functions, as well as AV1, HEVC, H.264 video codec functions and VP9 stream decoding. From the perspective of micro-architecture, function and design, Intel Arc is indeed able to keep up with the new generation of industry technology in the first-generation product design, meeting the needs of Modern GPUs.

Xe media engine supports AV1, HEVC, H.264, VP9 and other video codecs.

The Xe HPG core architecture is based on 1 set of Render Slices, with 4 sets of Xe-Core and 4 sets of Ray-Tracing units. This generation of the highest-level Arc A770 core uses 32 Xe-cores, 32 Ray-Tracing units, and 512 XMX engines composed of 8 sets of Render Slices.

The 1 Xe-Core contains 16 256-bit Vector Engines, 16 1024-bit Matrix Engines, and 192KB Shared L1$/SLM memory. It can process FP+INT+XMX instructions at the same time, and has more efficient Thread Control and keeps the engine in sync.

The Xe Vector Engine has a dedicated FP execution port and a shared INT/EM execution port, which can execute instructions of 16 FP32 ops, 32 FP16 ops and 64 INT8 ops per clock cycle. In addition to having a dedicated execution port and using a 4-deep systolic array design, the XMX matrix engine can execute 128 FP16/BF16 ops, 256 INT8 ops, and 512 INT4/INT2 ops per clock cycle.

Ray Tracing and XeSS’s Modern GPU

From the core architecture design, Xe HPG, in addition to the Vector Engines required for the GPU, also has the XMX matrix engine design required for AI, and has an independent Ray-Tracing unit, which further integrates Rasterization and Ray Tracing. The hybrid rendering function.

Hybrid Rendering.

The ray tracing algorithm can also be processed by the Compute Shader of the general GPU, but it will take a lot of time, which makes it unable to meet the requirements of real-time ray tracing of the game. Therefore, each Xe-cores has a Thread Sorting Unit and Ray -Tracing unit.

The Ray-Tracing unit of Xe-cores can calculate 12 Box Intersections and 1 Triangle Intersections per cycle, and has a BVH Cache to store ray tracing data, and collect the same ray data in the same Shader through the Thread Sorting Unit implementation, which greatly improves the performance of real-time ray tracing.

The hardware ray tracing unit designed by Arc GPU supports APIs such as DXR 1.0/1.1 and Vulkan RT, and has an asynchronous Thread Sorting Unit, and Ray Tracing Unit. Each Pipeline can execute 2 Ray Traversal, 12 Box Intersections per cycle and 1 Triangle Intersections.

Arc ray tracing unit functionality.

Real-time ray tracing can bring more realistic lighting, reflection and ambient occlusion to the game, but it also greatly increases the GPU’s computational load. At the same time, when players pursue 4K high-resolution games, the traditional GPU rendering performance cannot be overloaded. , it needs to be accelerated with the help of AI through “XeSS super-resolution” technology.

Under the same 4K rendering, with the help of XeSS, the rendering time can be greatly shortened and the performance can be improved, and the similar picture rendering can be maintained.

The game engine needs to provide: low-resolution rendering images and Motion Vectors, which are handed over to XeSS to generate high-resolution game images through AI deep learning Upscaling technology and Frame History feedback, which can improve game FPS performance and also Features such as high resolution and ray tracing are available.

In addition, in addition to Intel’s own Arc GPU support, XeSS also has a compatibility mode that supports other GPUs. In the future, there will be a variety of games to support, the first wave of “Tomb Raider: Shadow”, “Htiman 3” and “Ghost Line: Tokyo” and other games that provide XeSS technology.

Adobe Premiere Pro 2022  video editing software, using the self-developed Mercury Playback Engine GPU acceleration, can use the GPU’s encoding engine to accelerate the image output speed. The test project 1 is the company’s 1080p60fps out-of-the-box video; the BigMix4K project uses 3 segments of FinalAdjusted_MPE 1920×1080 images to form a 4K timeline for H.264 and HEVC format output.

In terms of performance, the Arc A770 is much faster than the RTX 3060 at 4K output, but is quite close to the RTX 3060 at 1080p processing speed. As for the A750, the error encountered in this test project cannot be output smoothly, which may also be a problem related to the driver and the system. (Need to wait for Adobe and Intel updates.)

Premiere Pro 2022 video output test, the shorter the second, the better.

DaVinci Resolve 18  is a purely GPU-accelerated video editing program, including powerful color correction and special effects functions, and directly using CUDA core computing, so that the playback and output of video clips have very good performance.

The test mainly uses 4K60 H.264 AVC to convert and output to AV1 encoding; and Wedding_Heavy_Style 4K24 wedding documentary with more special effects, as well as SuperScale 4x HDsource, SuperScale 2x 4Ksource’s heavier output performance test.

Arc A770 only needs 20 seconds to complete the AV1 output, but the A750 also encounters Error in this project and cannot be executed. The rest of the graphics cards do not support AV1 encoding so cannot be tested. As for other output performance, DaVinci Resolve 18 has better performance for RTX 3060, but Arc 770 is faster than RX 6600 XT.

DaVinci Resolve 18 video output test, the shorter the second, the better.

Blender  is a cross-platform, open source 3D authoring tool that supports various 3D tasks: Modeling, Rigging, Animation, Simulation, Rendering, Compositing, and Motion Tracking. For the test, use Blender Benchmark 3.3.0 to test the rendering work of the Demo project.

In the Blender Benchmark 3.3.0 test, the Arc A770 still loses to the RTX 3060 in performance, but it still beats the RX 6600 XT.

Blender, the higher the better.

Intel Arc A770, A750 3DMark benchmark performance test

The 3DMark Fire Strike  performance test is a test scenario for the mainstream DirectX 11 API, testing the performance of 1080p, Extreme 1440p and Ultra 2160p respectively.

Judging from the total score, the Arc A770 scored 30,500 points, and the Arc A750 also had a high score of 28,358 points. It beat the RTX 3060 by a considerable amount in the running points, and also beat the comparative RX 6600 XT.

The A770 is 43% faster than the RTX 3060 in Fire Strike and 7% faster than the A750. As for the A750, it is 34% faster than the RTX 3060. If the object of comparison is the RX 6600 XT, the A770 is 16% faster and the A750 is 8% faster.

3DMark Fire Strike, the higher the score, the better.

3DMark Time Spy  is a test scenario designed with DirectX 12 API, which is also locked in AAA game level, and tests the performance of 1440p and Extreme 2160p respectively.

The gap under the DX12 API is slightly narrowed. The Arc A770 has a total score of 13,895 points, and the A750 has a score of 13,413 points, which also beats the comparative RTX 3060 and RX 6600 XT.

The A770 is 49% faster than the RTX 3060 in the Time Spy project and 4% faster than the A750. As for the A750, it is 44% faster than the RTX 3060. If the object of comparison is the RX 6600 XT, the A770 is 37% faster and the A750 is 32% faster.

3DMark Time Spy, the higher the score, the better.

For the ray tracing test, 3DMark Port Royal  adds ray tracing function to the scenes in AAA games, testing the ability of the new generation GPU for hardware ray tracing acceleration. At the same time, the DXR test is a functional test using the DirectX Raytracing API.

The Arc A770 unexpectedly scored 32.04 FPS in the Port Royal test, while the A750 also managed 30.66 FPS, beating the RTX 3060 and RX 6600 XT.

The A770 is 37% faster than the RTX 3060 in the Port Royal project, and 5% faster than its own A750. As for the A750, it is 31% faster than the RTX 3060. If the object of comparison is the RX 6600 XT, the A770 is 54% faster and the A750 is 47% faster.

3DMark Port Royal, the higher the score, the better.

The functions of 3DMark XeSS and DLSS Feature test can compare the performance difference before and after the technology is turned on. Arc A770 has a performance of 29.17 FPS under XeSS Off, and it increases to 43.59 FPS with XeSS Ultra Quality acceleration enabled; while Arc A750 increases from 27.86 FPS to 41.87 FPS.

However, because the test scenarios are different from DLSS, direct comparisons cannot be made.

3DMark XeSS / DLSS Feature test, the higher the score, the better.

Intel Arc A770, A750 – 4 Gaming Gaming Benchmarks

4 e-sports games : “Rainbow Six: Siege”, “League of Legends”, “APEX Heroes” and “CS:GO”, etc., are all skill-heavy, team-based tactical competitive shooting, DOTA-type games, so the game When the picture quality and details are not high, the FPS of the game is also an average of more than 100 frames. Tested at 1080p, 1440p, and the highest settings for special effects.

It’s just that in terms of e-sports high FPS projects, Arc A770 and A750 seem to need some time to optimize. Only “APEX Heroes” has higher game performance, and the other three game performances all lose to the comparison objects.

Among them, “Rainbow Six: Siege” may be caused by the game update, which may have to wait for future updates to solve the problem of low test performance.

1080p gaming test, the higher the better.
1440p gaming test, higher is better.

Intel Arc A770, A750 – 12 Gaming Benchmarks

The average performance of 12 AAA games is tested with 1080p resolution and full special effects, including the entry-level “F1 2021”, “Forza Horizon 5” racing game, “Tomb Raider: Shadow”, and the movie game “Death Stranding” , “Gears of War 5”, “The Division 2”, “Horizon: Expect Dawn”, and the performance-heavy “Forbidden Land 3”, “Assassin’s Creed: Viking Age”, “Blood 2”, “God of War” , “Microsoft Flight Simulator” and other tests.

First of all, the 1080p resolution Arc A770 averaged 96 FPS in 12 games, the Arc A750 88 FPS, and the RTX 3060 averaged 91 FPS. However, at this resolution, the RX 6600 XT won the championship with an average of 101 FPS.

From this performance point of view, Arc A770 and A750 can meet the performance requirements of 1080p and AAA games. Even the masterpieces that consume resources have a very good performance, but “Microsoft Flight Simulator” still makes A750 feel a little too difficult.

1080p AAA gaming test, higher is better.

At 1440p resolution, the Arc A770 achieved an average of 73 FPS for 12 games, and the Arc A750 averaged 67 FPS. This test not only beat the RTX 3060 with an average of 67 FPS, but also beat the RX 6600 XT with an average of 71 FPS.

Arc A770 can provide good 2K game performance, and even games with heavy performance can maintain an average of more than 60 FPS, but “Microsoft Flight Simulator” is relatively difficult. Although the A750 is above 60 FPS on average, the performance of “God of War” and “Assassin’s Creed: Viking Age” is lower.

1440p AAA gaming test, higher is better.

Intel Arc A770, A750 – 8 light-chasing game tests

For the 8 light-chasing DXR game tests, the most popular “Electric Riders 2077”, “Ghost Line: Tokyo”, “Marvel Interstellar”, “Htiman 3”, “Polar War Cry 6”, “Htiman 3” are used. Games such as Evil Castle Village and Tomb Raider: Shadow were tested. Test the resolution of 1080p and 1440p. In addition to the maximum settings of special effects and light tracking, functions such as DLSS / FSR / XeSS will also be enabled. For detailed settings, please refer to the chart description.

The light pursuit masterpiece “Electric Rebel 2077” only averages 57.3 FPS when Arc A770 can only use FSR acceleration, compared to an average of 66.8 FPS under RTX 3060 DLSS acceleration, compared to games that rely heavily on light pursuit performance, this part Still the RTX 3060 is stronger. But “Ghost Line: Tokyo” can be tied Arc A770 97.9 FPS, RTX 3060 98.8 FPS.

From the average of 8 games, the Arc A770 averages 94 FPS, the A750 averages 81 FPS, and the RTX 3060 averages 95 FPS. In terms of visible light tracking performance, NVIDIA is still strong, but the performance of the Arc A770 directly beats the RX 6600 XT (77 FPS average).

1080p DXR gaming test, higher is better.

After the ray tracing resolution was increased to 1440p, although the RTX 3060 could not meet the performance of “Electric Rider 2077”, it still slightly outperformed the Arc A770 and A750. For other games, in addition to the Arc A750’s low performance in “Marvel Interstellar”, the A770 is also capable of 1440p light chasing game cards.

From the average of 8 games, the Arc A770 averages 74 FPS, the A750 averages 63 FPS, and the RTX 3060 averages 71 FPS.

1440p DXR gaming test, higher is better.

Intel Arc A770, A750 Power Consumption and Temperature Measurements

The power consumption and temperature test of the graphics card, using the Time Spy Stress test and “Electric Rider 2077” to test. The power consumption is measured using the PACT tool provided by NVIDIA, which can monitor the wattage provided by the PCIe slot and the power supply 12V.

In terms of graphics card temperature, the Arc A770 maintains a maximum temperature of 74°C in the stress test, and the A750 is 70°C. As for the 2077 game, the temperature will be slightly lower, but the other two compared are self-made cards, so it is normal for the temperature to be lower. condition.

GPU temperature test.

In the TBP power consumption test of the graphics card, in the Time Spy Stress test, the Arc A770 and A750 achieved an average power consumption of 227W, but in the 2077 game, the A770 190W and A750 164W. However, the power consumption of Arc is indeed higher in this comparison. Although the performance is better than that of the RTX 3060, it also pays more power to achieve it.

Graphics card TBP power consumption test.


This may be the game GPU three-point world that players are happy to see. The Intel Arc A770 and A750 did perform well. The Arc A770 averaged 73.9 FPS for AAA games at 1440p resolution and 74.4 FPS for DXR games, while Arc A750 is more suitable as an entry-level game card at 1080p resolution.

In this test, the Arc A770 and A750 are mainly compared with the RTX 3060. If the RTX 3060 is used as the benchmark, the Arc A770 has a performance lead of 6% and 9% in AAA games, while the A750 is a small loss. DXR games are similarly insignificant.

In terms of light-chasing games, Arc A770 and A750 do have the ability to fight against RTX 3060, and even light-chasing directly overtakes AMD’s performance, but now the support of light-chasing games is related to the popularity of XeSS. Where it needs to be sacrificed, I also expect more and more major games to support Intel Arc graphics cards at the first time.

The average overall score for game performance, based on RTX 3060.

However, the Xe HPG architecture of Intel Arc A770 and A750 is really low in performance for old games with old APIs. It also takes time for Intel to continue to optimize. Similarly, when XeSS technology has just been launched, it also takes time for game development. In this way, players can get the most complete new generation GPU game performance.

In terms of US dollar MSRP pricing, Arc A770 and RTX 3060 are actually cost-effective. In other words, as long as the price of Arc A770 in Taiwan is about 10,000 yuan as the RTX 3060 currently sold, the price of A750 is NT$9. At a price within a thousand yuan, this can really make players tempted.

Intel Arc A770 A750

In a word, Intel Arc A770 and A750 will go on sale at 3:00 pm Taiwan time on October 12th. As long as the price in Taiwan is reasonable or even better, then the release of this wave of Arc can be said to be a success, but it is more difficult to drive it in the future. Maintenance, game optimization, and enabling more games to use XeSS acceleration and ray tracing support, this is the mission that the original Arc needs to achieve, so that the next generation can expect Intel to launch a 4K-level graphics card.

The three major players scramble for the entry-level, mainstream cost-effective game graphics card market, so that players have better choices, and manufacturers can really launch products that meet players’ expectations and budgets.

Business hours: Taiwan will start the “Intel Arc Pop-up Store” event in the indoor exhibition area on the 1F of Guanghua Shopping Center on 10/21. Players who are interested in Arc should also come and experience it.

10/28 The upcoming Call of Duty: Modern Warfare II 2022 will support Arc’s XeSS and ray tracing capabilities.
