![]() ![]() ![]() Improving the front-end - deeper and smarter IPC has become more important as liberal increases in frequency have dried up: reliably hitting 5GHz on any modern processor is difficult.ĪMD claims Zen 2, whose execution cores are hewn from a leading-edge 7nm process, increases IPC by a full 15 per cent compared to original Zen, which is impressive given the base architecture is familiar, and that's without taking any additional frequency headroom into account. Zen 2, which began life in mid-2015 according to CPU chief architect Mike Clark, was designed primarily to boost the all-important instructions per clock cycle (IPC) metric which historically has been lacking on AMD chips when compared directly to Intel. This makes implicit sense because AMD made a clean break with Zen compared to the maligned Bulldozer/Excavator core.Įvolutionary designs enable engineers to pick off all the low-hanging fruit missed first time around, iron out bottleneck kinks, and then focus on laying down transistors that enhance performance. Zen 2 - Building on momentumįirst off, Zen 2 is an evolution of first-generation Zen rather than a grounds-up design. It is meaningful to under the upcoming benchmarks with solid knowledge of what Zen 2 brings to the table, how it is better and more efficient than its Zen and Zen+ predecessors powering Ryzen 1st and 2nd Generation chips, respectively, and how well it compares against Intel's premium mainstream chips in a wide range of benchmarks. In this review well be focussing on the CPU releases, so head on over here for an in-depth review of the new graphics, compared against Nvidia's recently-released RTX Super cards. The Zen 2 CPU and Navi GPU architectures are officially released to retail in the form of the Ryzen 3rd Gen processors and Radeon RX 5700/XT GPUs. Today, July 7, is a busy and important day for AMD.
