What CPUs have TSX?

For now, TSX will be disabled on Skylake, Kaby Lake, and Coffee Lake (6th, 7th, and 8th generation) CPUs due to security issues. No other Intel CPUs will be affected as of yet, but it remains to be seen if TSX will be patched out across further generations.

What is Intel Transactional Synchronization Extensions?

Intel® Transactional Synchronization Extensions (Intel® TSX) are an extension to the x86 instruction set architecture that adds hardware transactional memory support to improve performance of multi-threaded software.

What is TSX computer?

Transactional Synchronization Extensions (TSX), also called Transactional Synchronization Extensions New Instructions (TSX-NI), is an extension to the x86 instruction set architecture (ISA) that adds hardware transactional memory support, speeding up execution of multi-threaded software through lock elision.

Does Ryzen have TSX?

While AMD Ryzen CPUs do not support TSX, recent tests of this game console emulator revealed performance improvements there too.

What is TSX RPCS3?

TSX is an instruction set that adds hardware transactional memory support, which is a very good addition to have when looking for a new CPU for RPCS3.

How does transactional memory software work?

Definition. Software transactional memory (STM) is a method of concurrency control in which shared-memory accesses are grouped into transactions which either succeed or fail to commit in their entirety.

What is lock elision?

In sum, lock elision is a fast path to speed up locks and make them lock-less, under the right conditions. Because the hardware can discover parallelism opportunities automatically, elision also allows the programmer to spend less effort on manual, fine-grained locking.

What is transaction in STM?

A transaction is a unit of work seen from a system user’s point of view. A transaction consists of a sequence of operations, some of which are performed by a system, persons or devices that are outside of the system. Transaction begin with Birth-that is they are created as a result of some external act.
