Intel offers a more detailed cooling solution for its Arc A770 Limited Edition graphics card and shows its overclocking potential. Intel’s ArcA770 IBC features an amazing shroud design, high-end cooling and PCB components that can easily clock up to 2.7 GHz while operating at a quiet 39 dBA.
Intel TAP and Ryan Shrout were on hand to demonstrate a full overclock of the Arc A770 Limited Edition graphics card. The entire overclocking process was done on the Arc Control software, which has many bug fixes in recent driver updates and is more responsive than ever before. For the A770, Arc Control will allow users to configure a total of six different metrics, which include.
GPU performance boost (shifts the curve up)
GPU voltage offset (shifts the voltage up)
GPU power limit (raises/lower the power limit or TBP)
GPU temperature limit (raise/lower the target temperature)
Fan speed control (set fan mode to fixed/auto)
Fan speed (Increase/decrease fan speed)
The Arc control panel can be brought up in-game by pressing Alt+I (customizable). The tool itself acts as a real-time monitoring panel and provides a very handy in-game overlay that gives the user information about GPU voltage, GPU clock, GPU temperature, GPU power, and GPU activity. During this particular overclock, TAP did not go all out, but used some minor tweaks, but still boosted the speed to 2.7GHz compared to the default peak speed of 2.4GHz. this means that the clock speed was increased by 12.5%, which resulted in a 6.6% increase in Hitman 3’s FPS. the GPU power limit and temperature limit were raised to the maximum (228W/ 90C), while the voltage was pushed to +50mV and the GPU performance boost slider was moved to 37.
Interestingly, the fan speed is kept at a fixed 50% (1872 RPM) resulting in a peak temperature of 80C. This is very impressive and with the auto-profile we can definitely expect temperatures to hover below 80C, even up to 70C at peak load. the card runs at 39dB in a closed case and 35dB in an open case, which is very quiet. All this is an impeccable reference design that comes with a great cooling solution and an even better design. reference models like the ArcA770 and ArcA750 Limited Edition will feature nice coolers and some of the main highlights include.
Die-cast aluminum frame
Heat dissipation solution with steam chamber and extended heat pipes
Screwless shroud design
High-performance axial fan with 15 blades
Chamfered edges
Full back panel with a matte finish
90 fully controllable diffused RGB LEDs
Invisible black I/O bracket
4 display outlets
The Arc A770 Limited Edition features a new diffused RGB module inside the shroud that gets rid of the hot spots encountered in low-quality RGB shroud designs. It provides more uniform RGB lighting for the various RGB areas (Arc A770 has 4: fan, ring, back, logo.) The Arc A770 Limited Edition features a copper homogeneous thermal plate that has four massive heat pipes running through it, topped with a high-density stack of aluminum fins to dissipate heat from the GPU and other critical components on the PCB. the PCB itself is a 6 phase VRM design with Power is obtained through an 8+6 pin connector configuration.
The Arc A770 Limited Edition has three DP 2.0 and one HDMI 2.1 port, the card uses a PCIe Gen 4.0 x16 interface and has eight GDDR6 memory modules scattered around the Alchemist ACM-G10 GPU. These are 16Gb modules, or 2GB each, for a total of 16GB of memory capacity. Graphics card partners will have the option to design their A770 with either 16GB or 8GB of memory.
