As CPUs and support chipsets become more complicated and enriched with features, it has become necessary to perform some explicit initialization to configure the platform for best possible real-time performance. As features which affect this performance have been found the product has changed to configure them. This article lists the product versions of INtime for Windows which support different CPU families. Such features and technologies include SpeedStep, C1(E) states (Core2), C-states (Nehalem and later) and others. The Sandy Bridge family also required a change in the kernel to support the new floating-point architecture.
The explicit processor initialization started with the Core2 processor family, to fix a hardware bug in the C1(E) implementation, but has been extended back to the Core and P4 families to disable SpeedStep.
If a particular release introduced support for a particular processor architecture that does not necessarily preclude the use of the processor with earlier versions of the software but that is not recommended for best performance. The exception is the Sandy Bridge (and later) architectures which require version 4.01.11280 or later to operate correctly.
The dates indicate when processor support was added and the product release version which first included that support.
