Speed Select Technology is a set of a new family of features designed to give you more active and nuanced control over CPU performance and customize per-core performance. By configuring the performance of specific cores and affinitizing workloads to those cores, higher software performance can be achieved. Intel® SST—Performance Profile (PP): Configure your CPU to fit changing workloads The first feature in the family, Intel® SST-PP enables improved server utilization and reduced qualification costs by letting you configure a single server (not several) to match fluctuating workloads. One flexible server, multiple configurations—optimized TCO is the natural result. Intel® SST—Base Frequency (BF) The Intel® SST-BF feature lets you control and direct base frequency, essentially allowing you to ‘power-up’ for your most critical workloads, at the most critical times. And when you can micro-allocate performance like that, you macro-improve performance, overall. Specialized SKUs make the fine-tuning even finer To more closely meet your specific needs, our specialized SST CLX SKUs utilize Intel® Speed Select Technology features to take the control and performance to a higher level, still. Networking/NFV Specialized SKUs : Optimized for Networking and Network Function Virtualization (NFV) workloads, these SKUs let communication service providers in particular offer improved, scalable performance in two ways: First, the base frequency has been defined for Networking and NFV WLs. Second, the SST-BF feature lets you direct more frequency to higher priority workloads, boosting Virtual Network Functions (VNFs) performance when you need to. Speed Select SKUs : These SKUs have the SST-PP feature. Designed to lower costs and reduce data center complexity, Speed Select SKUs enable CPU SKU consolidation, bringing down platform qualification costs with fewer systems to test and validate.
