Advantages of CapFrameX for Multi-Run Benchmarking

Benchmarking computer hardware requires precision, repeatability, and a large enough sample size to account for system variance. This article provides an overview of how CapFrameX revolutionizes hardware testing through its multi-run frame data aggregation features. By exploring its ability to automate statistical analysis, filter out anomalous data, accurately calculate frame time percentiles, and integrate hardware telemetry, this guide explains why CapFrameX is the superior choice for compiling multi-run benchmark results.

Eliminating Run-to-Run Variance

A single benchmark run is rarely enough to determine the true performance of a CPU or GPU. Background operating system tasks, dynamic boost clocks, and thermal fluctuations can skew the results of an individual test. CapFrameX solves this by allowing users to easily aggregate data from multiple runs of the same test scenario. Combining three, five, or more runs neutralizes random system hiccups and establishes a statistically reliable baseline.

Automated Outlier Detection

When performing multiple benchmark runs, a sudden background process might cause a massive frame drop during one specific pass. In the past, testers had to manually comb through data to spot these ruined runs. CapFrameX features built-in outlier detection that automatically flags runs that deviate significantly from the median performance. Users can configure the outlier percentage threshold, allowing the software to automatically exclude corrupted runs from the final aggregated score.

Accurate Percentile Calculations

Calculating average frames per second (FPS) across multiple runs is simple, but calculating accurate 1% and 0.1% low frame times is complex. Simply averaging the 1% lows of three different runs is mathematically incorrect and yields flawed data. CapFrameX handles this properly by pooling the raw frame time data from all selected runs before calculating the percentiles. This ensures that the reported 1% and 0.1% lows represent the true frame pacing performance across the entire testing session.

Streamlined Workflow and Time Savings

Without CapFrameX, aggregating multi-run data requires exporting raw CSV files from capture tools like PresentMon and manually building complex formulas in spreadsheet software. CapFrameX eliminates this tedious process. Built directly on top of Intel’s PresentMon, it captures the data and allows users to highlight multiple recordings in the interface and merge them with a single click. This drastically reduces the time spent on data entry and prevents human error.

Aggregated Sensor Telemetry

Frame rates only tell half the story in hardware benchmarking; thermal and power metrics are equally important. Alongside frame times, CapFrameX logs vital hardware telemetry, including GPU power draw, CPU usage, clock speeds, and temperatures. When you aggregate multiple runs in CapFrameX, it simultaneously aggregates this sensor data. This provides testers with an accurate average of power consumption and thermal performance across the entire test suite, rather than relying on a single snapshot.

Customizable Comparison Charts

Once the multi-run data is aggregated, CapFrameX generates a new, single entry in your capture library. This aggregated file can be immediately used in the software's comparison tab. Testers can pit aggregated datasets from different graphics cards or processors against each other, instantly generating clean bar charts, frame time graphs, and L-curves without needing external graphing software.
