Worlds biggest over clocker12/14/2022 And that is with air cooling, not water cooling. Both of these chips had a target design frequency of around 4 GHz, but they are capable of going faster and sometimes do. The current Power8 chip and the impending and future Power9 chip have among the highest clock speeds in the industry. But Intel has been schooled by database makers like Microsoft and Oracle, who often get custom processors made by Intel for their iron so they have fewer cores that clock higher and therefore can get more single-threaded or lightly multithreaded work done in a given unit of time. This has certainly happened in the Xeon processor line from Intel, and it is what happens when the needs of search engine makers – the few that there are – outweigh the needs of enterprise companies doing traditional OLTP processing on relational databases. Still, it is a fact of physics that clock speeds on processors either flattens or comes down as the number of cores goes up. A lot of the performance improvements that companies are getting with modern CPUs is because they are wider and more clever in that they squeeze more work out of each clock cycle. The pace of process shrinks on chip manufacturing techniques is slowing, and the jumps between nodes are getting stretched out. But if anyone can crank the clocks high on a processor, it is IBM with its Power and System z engines, and we think it can push them a little higher and give certain customers who have a need for speed something to get excited about. Well, that was six years ago, and that sure as hell did not happen then and it is not going to happen now. Remember way back in 2000, when Intel, the world’s largest chip manufacturer and now the world’s dominant supplier of processors in the datacenter, said that it would be able to deliver processors that run at 10 GHz by 2011.
