MojoKid writes: AMD’s new Ryzen 3000 processors can boost as high as 4.6 GHz, a notable bump over previous Ryzen models, but what about AMD’s purported Instructions Per Cycle (IPC) gains? Has AMD’s Zen 2 architecture finally caught up to Intel’s Coffee Lake-based Core series processors in terms of IPC? To prove this out, HotHardware pitted a 12-core Ryzen 9 3900X against Intel’s 8-core Core i9-9900K in an array of tests, with both chips locked at 4GHz across all cores and four of the Ryzen CPU cores (or 2 CCXs) disabled (save for a couple of instances to show MT scaling). This allowed AMD’s fastest Zen 2-based CPU, with its full 64MB L3 cache complement, to compete against Intel’s current fastest desktop chip at identical clock speeds. A series of single-threaded benchmarks were run, in addition to some standard games tests, which are lightly multithreaded. The Intel and AMD multi-core processors essentially traded blows across a number of tests, but Intel won more often than not. The blue team notched IPC wins in SANDRA’s Dhrystone integer tests, Geekbench, POV-Ray, LAME MT, and the gaming tests. AMD stole single-threaded victories in SANDRA’s Whetstone FPU tests, Cinebench, and Y-Cruncher. While not an outright win for AMD, the company has obviously worked hard to improve 3rd Gen Ryzen IPC throughput, while its multi-core scaling is downright impressive.
