In the face of AMD's step-by-step approach, Intel launched two generations of products in 2021, of which the twelfth generation core launched at the end of October received the most attention, because this generation of Core uses a new size core architecture, PCIe 5.0 and DDR5, and is built with Intel7 (formerly 10nm SuperFin) process.
Although the twelfth generation of Core began to support DDR5 memory, considering the current shortage of DDR5 memory and high price, many players will prefer DDR4 memory. In the face of the user's low-cost use of the 12th generation Core demand, the motherboard that supports DDR4 memory is one of the focuses of the manufacturer. Rainbow brought a number of products at the same time as the release of the twelfth generation Core, among which the Rainbow CVN Z690 GAMING FROZEN V20, which cost 1699 yuan, is a motherboard that supports DDR4 memory.
The Rainbow CVN Z690 GAMING FROZEN V20 motherboard features a standard ATX form factor with four DDR4 memory slots and supports up to DDR4-4800MHz frequencies. The motherboard has a good scalability and power supply, thermal design, and supports Wi-Fi 6 wireless networks. Rainbow also promises to provide one-year replacement and four-year warranty services.
Outer family heat dissipation design
The CVN Z690 GAMING FROZEN V20 motherboard for testing continues the design style of the CVN series white, with a large area of silver metal brushed heat sink, taking into account the heat dissipation performance and texture, and the visual effect is better with the white side-through chassis.
The heat dissipation module of the motherboard is divided into three parts, the upper part is still the CPU power supply heat dissipation module, two pieces of frost condensation cooling armor, with full coverage of condensation and heat dissipation paste, bringing more efficient heat dissipation performance. The other thermal modules of the motherboard are the M.2 SSD and the South Bridge Heatsink, respectively.
The motherboard uses a new generation LGA1700 processor base that supports Intel's 12th generation Core desktop processors.
The motherboard offers four dual-channel memory slots for DDR4, with a single slot of up to 32GB of memory and a maximum capacity of 128GB.
In terms of hard drive support, the Rainbow CVN Z690 GAMING FROZEN V20 motherboard provides three M.2 SSD connectors and six SATA 3 connectors. It is important to note that the first and third M.2 interfaces support PCIe 4.0 and the second support PCIe 3.0 x4.
The 12th Core supports PCIe 5.0 channels, considering that there is currently no graphics card and SSD and other related products that support PCIe 5.0, Rainbow chose to support PCIe 4.0 on this motherboard, which greatly reduced the cost of players. Both PCIe slots are reinforced with metal for stability.
The motherboard is equipped with an Intel 2.5Gbit network card and an 8-channel sound card that provides players with outstanding sound performance through professional audio capacitors, audio splitting lines, and metal shields.
Rainbow CVN Z690 GAMING FROZEN V20 motherboard adopts 15+1 phase CPU power supply design, with F.C.C ferrite inductor, DrMOS tube, 10K black gold solid capacitor, to ensure the performance of 12th generation Core processors.
In terms of the I/O interface of the back, the more beautiful topic of rainbow selection is the I/O backplane, which makes the installation of the motherboard more convenient. The interface provides a DP, an HDMI video output interface, 4 USB2.0, 2 USB3.2 Gen1, TYPE-C supporting USB3.2 Gen2, a USB-A interface, an RJ45 network cable interface, 5 3.5mm audio interfaces composing 7.1 channels, and an antenna interface for wireless network cards. There is also a BIOS upgrade button on the back panel to facilitate players to upgrade the BIOS.
Rainbow CVN Z690 GAMING FROZEN V20 motherboard is powered by a flagship Core i9-12900K processor, the defender of memory selection Samsung B-die particles. Test bench CPU-Z, CineBench R15/R20/R23, AIDA 64 to test performance.
In cpu-Z's single-core running score, the i9-12900K scored 775.7. The CIneBench R15 has a CPU score of 3873, the CineBench R20 has a score of 9810 pts, and the CineBench R23 has a single and multicore score of 1886 pts and 26107 pts, respectively. The memory latency tested by AIDA64 is 86.9ns.
Product summary
From a practical point of view, DDR4 memory is still the choice of most users. Coupled with the higher power supply demand of the 12th generation Core, Rainbow, a motherboard that supports DDR4 and 15+1 phase power supply, is a good choice for players. The standard ATX version brings good scalability, temporarily abandoning the costly and unused PCIe 5.0, so that the price of this motherboard comes to 1699 yuan, which is a good choice for beginner players.
