While we await the formal IBM Power11 launch in 2025, IBM engineers are already working on compiler support for "future" post-Power11 processors with the GNU Compiler Collection (GCC)...

Intel Xeon 6300 vs. AMD EPYC 4005 SMT/HT Performance

Phoronix - Tue, 06/24/2025 - 00:00
While the latest Intel Core Ultra processors have done away with Hyper Threading (HT), Intel Xeon CPUs continue supporting HT/SMT, including with their latest Xeon 6300 series budget server processors. As the new AMD EPYC 4005 "Grado" processors also support Simultaneous Multi-Threading (SMT) and can be found at the same core/thread count count as the flagship Xeon 6369P processor, it makes for an interesting look at comparing the SMT/HT performance impact and power efficiency. Here are some benchmarks showing the Xeon 6300 against the AMD EPYC 4005 in SMT performance.
