X-bit Labs reports Intel will reveal loads of new details about Haswell at next month's Intel Developer Forum:
During four sessions dedicated to Haswell, Intel will discuss the new processor innovations in general as well as advanced vector extensions 2 (AVX 2), bit manipulation new instructions (BMI) as well as transactional synchronization extensions (TSX) instructions and their benefits in particular. In addition, the company will have a session called "Experiencing the 3rd and 4th Generation Intel Core Microarchitecture", which implies that the company will compare both current Ivy Bridge as well as future Haswell capabilities.
Since the world's largesty chipmaker has demonstrated Haswell chips for a number of times already, this time the company will likely show it working. Unfortunately, it is unlikely that the company will discuss performance benefits of the new micro-architecture in details.
