Microsoft SER Delivers Massive GPU Performance Gains

Microsoft's Shader Execution Reordering (SER) technology is proving to be a significant game-changer for modern GPUs. According to TechPowerUp, SER achieves up to 90% performance improvement on Intel Arc B-Series GPUs and 80% on NVIDIA Blackwell architecture, representing some of the largest software-driven performance gains seen in recent years.

What Is Shader Execution Reordering?

Shader Execution Reordering is a technique that restructures GPU shader workloads to maximize hardware utilization. It's particularly effective for ray tracing workloads, which tend to have highly divergent execution patterns that leave GPU cores idling. SER mitigates this by reorganizing shader threads into more coherent groups, dramatically improving throughput.

Why These Numbers Matter

A 90% performance increase on Intel Arc B-Series effectively means near-doubling of performance without any hardware change. For Intel's Arc GPUs, which have been competitive but have struggled to match NVIDIA and AMD at the top end, SER could be transformative. Similarly, the 80% boost on NVIDIA Blackwell shows that even already-powerful hardware benefits substantially from this optimization.

These gains have direct implications for PC gaming: better ray tracing performance means more games can enable high-quality lighting effects without sacrificing frame rates, making cutting-edge visuals more accessible to a wider range of hardware.
