The power, in this case, is the estimated GPU power and not the total board power GPU Power Limit allows configuration of the allowed GPU power consumption. However, I will only use the Performance Boost slider in this OC Strategy. When finetuning, we use both sliders to enable a higher voltage range and add extra frequency for each V/F point. That observation still stands with what we learned about the two overclocking sliders. In my original Arc A380 overclocking blog post, I observed that overclocking Arc A380 feels very similar to NVIDIA GPU overclocking. When the GPU boosts to a previously restricted voltage-frequency point, it will boost to that frequency and voltage. Note that this isn’t an actual voltage offset but enables higher V/F points. The empiric evidence aligns with this idea since a +100 offset returns a 110 mV increase in GPU voltage. We’ll get back to that later in the article. That presumably indicates the maximum voltage offset allowed for this GPU. In this case, the slider ranges from 0 to 258. GPU Voltage Offset enables the restricted parts of the factory-fused voltage frequency curve. At 100%, the GPU frequency is 2750 MHz which is a 300 MHz increase over the default maximum frequency of 2450 MHz. The slider goes from 0 to 100, with 100 presumably reflecting 100% of the maximum allowed frequency offset. GPU Performance Boost offsets each point on the voltage-frequency curve with a specific frequency. Let’s have a closer look at the function of each of the available overclocking controls in the Intel Arc Control software. Unfortunately, while it’s evident that these options are supposed to give some degree of manual control over the voltage-frequency curve, it’s not entirely clear from the interface what each option does exactly. Today, the tool still provides the same overclocking knobs as at launch. Since the beginning, Arc Control has provided enthusiasts with the tools to overclock their Arc GPU. Recently, Intel launched a standalone desktop mode version of Arc Control software, improving the user experience. In the beginning, many users complained about the useability and bugs. The Arc Control software is arguably one of the most controversial aspects of the Intel discrete graphics product launch. In our first overclocking strategy, we take advantage of the overclocking toolkit integrated into the Intel Arc Control software. OC Strategy #1: Basic OC with Intel Arc Control As you can see from the chart, the GPU works from 100 MHz at 0.660V up to 2450 MHz at 1.035V. The average GPU power is 62.579 watts.įor future reference, I also extracted the default voltage-frequency curve from the A380 GPU. The average GPU Global temperature is 59.0 degrees Celsius. When running Furmark GPU Stress Test, the average GPU clock is 2447 MHz with 1.026 volts, and the GPU Memory clock is 1937 MHz. Here is the benchmark performance at stock: Intel Arc A380: Stock Performance & V/F Curveīefore starting overclocking, we must check the system performance at default settings. However, it’s only available for native Linux and Windows Subsystem for Linux 2, not native Windows. Intel did release an extension for TensorFlow, which has experimental support for Intel Arc A-Series GPUs. We rely on the TensorFlow-DirectML plugin for AI Benchmark to run our deep learning workloads. The benchmark selection is similar to the one we used in our last GPU SkatterBencher guide. Simple Raytracing Benchmark (1080P, Basic) We use Windows 11 and the following benchmark applications to measure performance and ensure system stability. The system we’re overclocking today consists of the following hardware. Third, we maximize the GPU overclock using non-Intel software toolsīefore we jump into the overclocking, let us quickly review the hardware and benchmarks used in this overclocking guide.Second, we use Arc Control and do advanced overclocking with custom loop water cooling.First, we use Arc Control and do basic GPU overclocking with stock cooling.In today’s guide, we cover three overclocking strategies. The 6GB GDDR6 memory is clocked at almost 1937 MHz. It comes with a base clock of 2000 MHz and a boost clock of 2450 MHz. The Arc A380 is built on the TSMC N6 process and houses 8 Xe-cores. It supports ray tracing, deep learning accelerated XeSS, and DirectX 12 Ultimate. It uses the Xe-HPG variant of the Intel Xe GPU Architecture. It was the first ARC discrete graphics released in the market on June 14, 2022, at an MSRP of US$139.Īlchemist is the codename for Intel’s first-generation desktop discrete graphics. The Intel Arc A380 is the second-slowest graphics card in Intel’s Alchemist lineup.
