The 5G killer application is speed measurement, and the main application of PCIe 5.0 is running score:
Perhaps to alleviate the embarrassment of not having even one consumer PCIe 5.0 device available today, Intel recently released a video of installing and testing enterprise PCIe 5.0 SSDs on a 12th-generation Core desktop platform.
Since Intel's own SSD business has been sold to SK Hynix, this demo uses Samsung's enterprise-class SSD PM1743.
The PM1743 uses a 2.5-inch E3.S interface that only appears in the server, so a PCIe riser card is required to install it in a normal home desktop computer and occupies the only PCIe 5.0 slot on the Z690 motherboard. If you really want to use it under heavy load, I am afraid that you also need to add a fan in the reserved location to actively dissipate heat.
In the IOMeter theoretical bandwidth test, the Samsung PM1743 ran a maximum sequential read speed of 13829.37MB/s on the Core i9-12900K platform, almost double the PCIe 4.0 SSD.
PCIe 5. The number of flash channels for the current enterprise master of SSDs is usually greater than 8, while the consumer master is limited by the cost, space, heat dissipation, and flash I/O speed development level, and the first products on the market later this year are estimated to be difficult to fully utilize the bandwidth of the PCIe 5.0 interface.
XMG External Water Cooled Laptop:
XMG announced at CES 2022 the NEO 15 (E22) water-cooled esports laptop with optional external water cooling.
This 15-inch gaming book is equipped with an Intel Core i7-12700H processor and RTX 3080Ti unique display that can be connected to an external heatsink called XMG Oasis. The XMG Oasis is a small box of 186 x 203 x 75 mm that contains a 120mm radiator and water pump, water tank, and RGB and Bluetooth functions connected to the cooling circuit in the laptop via two hoses.
According to XMG's tests, the power limit of the CPU can be released from 60 watts to 72 watts and the GPU power from 136 watts to 155 watts with XMG Oasis. With the help of external water cooling, the notebook's own fan speed can be reduced by 50% during gaming or rendering, noise does not exceed 38 decibels, and provides better performance output.
The XMG Oasis water cooling system has a total of 230 ml of coolant, of which about 20 ml is in the cooling circuit inside the notebook. An external water cooling system can quickly connect and release the laptop, but the manufacturer recommends that users first turn off the computer and drain the coolant from the laptop when disconnected.
