Research from the College of William & Mary, Jefferson Lab, and Silicon Data reveals significant performance variability among identical GPU models rented from cloud providers. This "silicon lottery" means customers may not receive the performance they pay for, with some H100 PCIe GPUs showing up to a 34.5% difference in computing performance and H200 SXM GPUs exhibiting up to a 38% variation in memory bandwidth. The study suggests that manufacturing inconsistencies, rather than cooling or configuration, are the primary cause of these discrepancies. To mitigate this, researchers recommend that GPU renters benchmark their specific instances to ensure they are getting adequate performance for their investment. AI
