AMD claims an up to 35% increase in gaming performance over the previous-generation, and an up to 45% increase in creator performance (which is where it gets the confidence to stick to its core-counts from). The "Zen 4" CPU core dies (CCDs) are built on the TSMC 5 nm EUV (N5) node. Even the I/O die sees a transition to 6 nm (N6), from 12 nm. The switch to 5 nm gives "Zen 4" 62 percent lower performance for the same performance, or 49% more performance for the same power. versus the Ryzen 5000 series on 7 nm. The "Zen 4" core along with its dedicated L2 cache is 50% smaller, and 47% more energy efficient than the "Golden Cove" P-core of "Alder Lake."

AMD Announces Ryzen 7000 Series "Zen 4" Desktop Processors
AMD today announced the Ryzen 7000 series "Zen 4" desktop processors. These debut the company's new "Zen 4" architecture to the market, increasing IPC, performance, with new-generation I/O such as DDR5 and PCI-Express Gen 5. AMD hasn't increased core-counts over the previous-generation, the Ryzen 5 series is still 6-core/12-thread, the Ryzen 7 8-core/16-thread, and Ryzen 9 either 12-core/24-thread, or 16-core/32-thread; but these are all P-cores. AMD is claiming a 13% IPC uplift generation over generation, which coupled with faster DDR5 memory, and CPU clock speeds of up to 5.70 GHz, give the Ryzen 7000-series processor an up to 29% single-core performance gain over the Ryzen 5000 "Zen 3."AMD claims an up to 35% increase in gaming performance over the previous-generation, and an up to 45% increase in creator performance (which is where it gets the confidence to stick to its core-counts from).
