Acer Predator BiFrost Intel Arc A770 OC Graphics Card Unboxing

I saw this card on Predator Gaming's social media X before the Intel Arc A770 and A750 performance ban was lifted, and I have to say that it struck a chord with me at the time, and I finally got the chance to get my hands on it and test it out in the box after almost two years!

Acer Predator BiFrost Intel® Arc™ A770 OC uses the Intel Arc A770 graphics card core, which is cheaper than the Intel Arc A770 Limited Edition graphics card by 2,000 bucks at the early bird discount price before it goes on sale, so I can only say that Acer doesn't give Intel face.

The 6 nm ACM-G10 graphics card core uses the Intel Xe HPG architecture, codenamed Alchemist, and is comprised of 32 X^e-The Acer Predator BiFrost Intel Arc A770 OC is powered by 16 GB of GGR6 graphics memory and has a TGP of 210W, which can be increased to 235W in Turbo mode and is officially recommended to be used with a 650W or higher power supply. The official recommendation is to use it with a power supply of 650W or higher.

For everyday use, the A770 supports GPU APIs such as DirectX 12 Ultimate, AV1, HEVC, H.264 video and audio codecs, VP9 streaming decoding, and more.

∆ Basic features printed on the back.

∆ Acer Predator in large letters.

∆ The ADATA UV350 32GB UFD is included in the box with the graphics card driver and Predator BiFrost App, but the author is used to download the latest version of the driver directly from the official website.

 

The graphics card does not come with a gold finger protector or screen output dust plug, which is a shame because if you want to protect it or collect it, you'll need to buy it yourself, but I guess it's just a matter of cost.

The Acer Predator BiFrost Intel Arc A770 OC graphics card measures 267 x 117 x 42 mm in length, width and height, and features a cooling module system that utilizes a 5th generation AeroBlade 3D Blade metal cooling fan and a Ø 92 mm diameter axial flow FrostBlade 2.0 fan.

The smaller AeroBlade 3D Blade fan on the left has a slightly refractive lighting effect when powered on, and this small fan dissipates heat in the form of a turbofan, which means that it exhausts heat away from the screen's output ports, while the larger FrostBlade 2.0 fan dissipates heat directly through holes in the reinforced back panel.

The metal-reinforced backplate enhances the physical strength of the PCB itself and aids in the cooling of the ICs on the back, and is styled with the Acer Predator logo and text on the rear, and most importantly, the rear of the graphics card has large openings above the cooling fins for the axial flow FrostBlade 2.0 fan.

∆ Overview of the enhanced back panel of the graphics card.

∆ Textured decoration on the back, no tamper-evident sticker on the display card screws... so ....

∆ Reinforced backplate opening to allow aft airflow to pass through the cooling fins and then directly through the heat exhaust.

 

As I mentioned earlier, this card uses a turbo fan on the outside to further compress the thickness of the card with the internal cooling module, making the entire card only 42 mm thick, which means that it will be used in the 2 Slot PCIE mounting position of the chassis, which is quite suitable for M-ATX or Mini ITX motherboards or chassis mounting.

According to the author's actual test, the overall power consumption of TGP (Total Graphics Power) is around 210~220 W by default, and the graphics card is powered by two PCIE 8-Pins; it is officially recommended to use a power supply with more than 650W, however, if you are using the Intel i9 or AMD R9 processor with higher power consumption, then the author would recommend to increase the power supply wattage even higher to be more safe. However, if you are using Intel i9 or AMD R9 processors with higher power consumption, the author would recommend to increase the wattage of the power supply to be more safe.

With a thickness of only 42 mm, the ∆ graphics card occupies only two slots for PCIE mounting, making it ideal for platforms with limited space.

The ∆ is powered by 2x PCIE 8-Pin and can be upgraded by using the old power supply to upgrade the graphics card.

 

The graphics card has four display outputs: 1x HDMI 2.1, 3x DisplayPort 2.0, and a large hole underneath the graphics connector for the turbofan to exhaust the cooling airflow out of the graphics card.

Acer Predator BiFrost Intel Arc A770 OC Card Teardown Showcase

Next, I will disassemble this Acer Predator BiFrost Intel Arc A770 OC graphics card manually, and I would like to remind all gamers that "I don't recommend or promote consumers to disassemble the graphics card by themselves, as it may lead to human failure and loss of warranty", and that the author will disassemble it only for display purposes for everyone's reference.

The screws on this card are not stickers, and the whole disassembly process is easy, but there are a lot of screws, so if you really want to disassemble the card, you should remember to arrange the screws and remember from which side you removed them.

The internal cooling module of the graphics card uses four flat heatpipes with a copper base to conduct heat, and the overall concept is similar to that of a laptop, so it looks like Acer has transplanted the technology from the laptop side!

∆ Most of the screws are simply removed from the direction of the back of the graphics card, there are so many screws in the reinforced backplane alone.

∆ Almost all of the ICs on the back of the graphics card have supplemental cooling.

∆ Reinforced backplane contact surfaces are also metal contact material surfaces.

∆ Thermal Module Removal.

∆ This card uses a skin-colored thermal medium to help conduct heat in ICs that generate less heat, but it is not a thermal paste, it is more like a paste, and the core of the card still uses a thermal paste.

∆ Skin-colored thermal media is not recommended to be erased. The graphics card memory and the core share a copper-backed heat shield, and there is additional metal soldered between the graphics card memory and the heat shield to compensate for the height difference.

The ∆ graphics card cooling module uses four heat pipes and a heat shield to help dissipate heat, similar to the concept of a laptop.

∆ The graphics card core layout is similar to the Limited Edition but still partially different.

Steel Nomad The tests will be conducted at 3840 x 2160, or 4K, and are for the DirectX 12 benchmark running Windows 10 and 11. The program supports Multi sub-pass rendering, which allows you to set which API you want to use when using GPU APIs such as Vulkan, Metal, and DirectX 12 on your graphics card. The Nomad can be configured to test with any of these APIs when the graphics card is using GPU APIs such as Vulkan, Metal, and DirectX 12. It also supports Geometry Rendering, Surface Illumination, Particles, Asynchronous compute, Volumetric clouds, Screen clouds, Screen-space shadows, Screen-space reflections, Volume illumination and more.

Since Steel Nomad does not have a CPU test, the CPU's main role in the test is to write a list of instructions for the GPU to execute. A large number of tasks are allowed to be performed throughout the course of the test project. For example, rendering is done through multiple CPU threads, one for each available CPU core. This will shorten the CPU rendering time and reduce the chance of the CPU becoming bottlenecked.

Nine AAA Masterpiece Games to Test

To test the AAA genre, which emphasizes on the experience of graphic performance and storytelling, the author chose to play "The Battle of the Birds", which is the first game in the AAA genre.Bloodshed 2_ Red Dead Redemption 2, _Electric Renegade 2077_Cyberpunk 2077, TheThe Hogwarts Legacy_Hogwarts Legacy, TheThe Witcher 3: Wild Hunt_The Witcher 3: Wild Hunt, Thewar god_God of War, _Horizon: Expecting Dawn_Horizon Zero Dawn_, _Horizon Zero Dawn_, _Horizon Zero Dawn_.Watch Dogs: Freedom Corps_Watch Dogs: Legion, TheHowl of War 6_Far Cry 6, _Assassin's Creed: Viking AgeAssassin's Creed Valhalla" and nine other 3A masterpieces plus a "Final Fantasy XIV: DAWNTRAIL Golden Legacy" were tested in the game.

Considering the fact that most gamers pursue the most beautiful screen performance rather than the highest frame rate performance when playing 3A games, the author also set the built-in "Highest" texture effect option in the AAA type of game test, and only some of the nine AAA games supporting Intel XeSS (Xe Super Sampling) technology set their settings to "Quality/Picture Quality" for the test. Tested to obtain a certain degree of frame rate increase while maintaining the screen performance as much as possible, the frame rate collection is also using the software record average (AVG) and 1% Low fps.

Conclusion

As Acer's first B2C Intel Arc graphics card, the Acer Predator BiFrost Intel® Arc™ A770 OC, attracts consumers with its cool appearance and cheaper price, using Intel Xe HPG architecture ACM-G10 core and 16 GB GDDR6 graphics memory, and paired with Intel XeSS (Xe Super Sampling) technology. Intel XeSS (Xe Super Sampling) technology brings gaming enthusiasts a third new 2K resolution entry graphics card besides NVIDIA and AMD, with an average of 144 fps or higher in high frame rate demanding FPS type games. In AAA games, which are more in pursuit of graphic performance, a total average of 78.4 fps was achieved for all nine games, and only a few games had to lower the mapping settings in order to successfully reach the passing frame rate of 60 fps.

For ray tracing games, which require more graphics card performance, the total average was 49.5 fps. With six games set to the "highest" graphics quality, only one game could exceed the average 60 fps game passing line. Xe Super Sampling) for performance, or lowering the mapping settings or 1080p resolution would be more suitable for gaming, in conclusion this card is positioned to meet the "2K entry" requirements when it was first released.

The graphics card itself is a good size for most compact or mini PC cases, but with the full preset PL1/PL2:210 W, even with the platform set up in a 24°C air-conditioned room on the barebones test rig, the card still reached a maximum temperature of 84°C, and overheating occurred in Furmark 2, which has the highest load pressure, and the frequency was temporarily reduced to a minimum. This is not good news for gamers who mostly install their cards in chassis, where the cooling environment is definitely not as good as on the bare test rig. However, the author disassembled the graphics card and replaced the thermal paste with Cooler Master MASTERGEL MAKER 40g thermal paste (thermal conductivity 11W/mK) after the test and conducted an additional round of testing. The maximum temperature of Furmark 2 was 83°C for 30 minutes, the temperature was lowered by one degree and there was no downclocking or degradation of usage. If consumers want to get the full performance of the graphics card without downclocking, it is recommended that they use the Predator BiFrost utility app to raise the temperature limit.
