AMD Threadripper 9980X 64-core benchmarks accelerate high-density AV1 encoding workflows

The transition to AV1 is reaching a critical inflection point as services like Netflix move toward 100% HDR catalog coverage. These benchmarks demonstrate the viability of 64-core HEDT workstations for offloading parallelized SVT-AV1 tasks from more expensive cloud instances. This hardware-specific data allows engineering teams to calculate precise ROI for on-premise encoding clusters against rising cloud compute costs. As SVT-AV1 version 4.2 introduces VMAF-specific tuning, high-core-count processors like the 9980X will be the primary drivers for achieving broadcast-quality compression at scale. Watch for updated SVT-AV1 software release notes in Q4 to see how Zen 5's improved AVX-512 handling further shifts the performance-per-watt curve.

The release of high-density benchmarks for the Threadripper 9980X comes as the industry settles on SVT-AV1 as the production standard for non-hardware-accelerated encoding. Per release notes from July 2024, SVT-AV1 version 4.2 introduced a TUNE-VMAF mode aimed at a 15% improvement in BD-rate, specifically targeting VOD and Random Access workflows. This software maturity has facilitated widespread adoption; per Free-Codecs and Netflix technical reports from January 2026, AV1 now accounts for 30% of all viewing hours on Netflix and 75% on YouTube. The codec's ability to reduce bandwidth requirements by one-third compared to AVC and HEVC has made it the default choice for large-scale distributions.

From a hardware perspective, the Zen 5 architecture (codenamed Shimada Peak) launched in late July 2025 at an MSRP of $4,999 for the 64-core 9980X variant, according to TechPowerUp and TechSpot reports. This generation maintains compatibility with the sTR5 socket, allowing operators of Threadripper 7000-series workstations to upgrade without full infrastructure overhauls. While early benchmarks from GamersNexus in August 2025 noted that compression gains were sometimes marginal, the architecture showed up to a 58% improvement in specific convolution and AVX-heavy tasks, which directly benefits the complex motion estimation and intra-prediction algorithms used in AV1 encoding.

This performance ceiling is critical as the market shifts from experimental use to mandatory deployment. Per Streaming Media reporting in March 2026, codec decisions have moved from engineering abstractions to C-level financial strategy due to new royalty structures like the Access Advance Video Distribution Patent (VDP) Pool. As patent pools begin licensing the hardware market, the efficiency of open-source encoders on high-performance silicon like the 9980X provides a predictable cost model for streaming providers navigating these new licensing and bandwidth landscapes.
