ASRock Z590 OC Formula Review



ASRock Logo

After almost a decade of total market dominance, Intel has spent the past few years on the defensive. AMD's Ryzen processors continue to show improvement year over year, with the most recent Ryzen 5000 series taking the crown of best gaming processor: Intel's last bastion of superiority.

Now, with a booming hardware market, Intel is preparing to make up some of that lost ground with the new 11th Gen Intel Core Processors. Intel is claiming these new 11th Gen CPUs offer double-digit IPC improvements despite remaining on a 14 nm process. The top-end 8-core Intel Core i9-11900K may not be able to compete against its Ryzen 9 5900X AMD rival in heavily multi-threaded scenarios, but the higher clock speeds and alleged IPC improvements could be enough to take back the gaming crown. Along with the new CPUs, there is a new chipset to match, the Intel Z590. Last year's Z490 chipset motherboards are also compatible with the new 11th Gen Intel Core Processors, but Z590 introduces some key advantages.

First, Z590 offers native PCIe 4.0 support from the CPU, which means the PCIe and M.2 slots powered off the CPU will offer PCIe 4.0 connectivity when an 11th Gen CPU is installed. The PCIe and M.2 slots controlled by the Z590 chipset are still PCI 3.0. While many high-end Z490 motherboards advertised this capability, it was not a standard feature for the platform. In addition to PCIe 4.0 support, Z590 offers USB 3.2 Gen 2x2 from the chipset. The USB 3.2 Gen 2x2 standard offers speeds of up to 20 Gb/s. Finally, Z590 boasts native support for 3200 MHz DDR4 memory. With these upgrades, Intel's Z series platform has feature parity with AMD's B550. On paper, Intel is catching up to AMD, but only testing will tell if these new Z590 motherboards are up to the challenge.

The OC Formula line from ASRock returns with the Z590 OC Formula. The ASRock Z590 OC Formula was designed in collaboration with Nick Shih to facilitate record breaking extreme overclocking.

The ASRock Z590 OC Formula features a powerful 16-phase VRM utilizing top-tier 90 A power stages along with a 12-layer PCB and even an OLED display. Along with the overclocking aids and features, the Z590 OC Formula also includes 2.5 Gb/s LAN and WiFi 6E, and a healthy complement of storage options.
