// performance varies by use, configuration and other factors. The buggy tsx implementation on core haswell processors was discovered by a developer outside intel, who reported it to the company, which then labeled it as an erratum (a known design flaw). Intel is disabling tsx in haswell due to software failures.
Intel Core Processor (Broadwell, No Tsx, Ibrs) Cores:
Otherwise, use the intel® uhd brand. If tsx was disabled by a firmware update then cpuid (via /proc/cpuinfo) should not show the tsx bit anymore. And the instruction should just cause an exception for invalid op.

Transactional synchronization extensions, aka tsx, are a backwards compatible set of instructions which first appeared in some haswell. // no product or component can be absolutely secure. The tsx instructions built into intel's haswell cpu cores haven't become widely used by everyday software just yet, but they promise to make certain types of multithreaded applications run much faster than they can today.

Intel® iris® xe graphics only: No tsx or vt it is entirely reasonable to expect. 4 cores / 4 threads / 1 cpu / 1 node.
