AMD Ryzen 9 7950X 16 Core CPU Review – Revisiting Zen 4 on ASRock’s X670E Taichi & Gigabyte’s X670E AORUS Xtreme

The ASRock X570 Taichi is styled in black and gold. The motherboard comes with the standard ATX form factor so compatibility won’t be an issue on a wide range of PCs. The Taichi theme looks absolutely brilliant and eye-catching on the motherboard as well as the overall design layout which has been upped from the past Taichi variants.

The board uses the LGA 1718 socket to support AMD Ryzen 7000 processors. The socket is compatible only with Ryzen 7000 CPUs for now but will also support future iterations on the AM5 platform.

Next to the socket are four DDR5 DIMM slots that can support up to 128 GB of dual-channel memory. These slots are rated to support EXPO profiles up to 6600 MHz (OC Plus). The DIMM slots feature metallic shielding around them for extra durability. Each slot is labeled, making it easier to install DIMMs in the proper orientation. DDR5 memory comes with a different latch position so forcing a DDR4 module into a DDR5 slot will cause permanent damage.

The ASRock X670E Taichi features a 22+2+1 (VCore/ VccGT/VccAUX)  phase digital power delivery that makes utilizes the Renesas RAA229628 PWM controller and RAA22010540 (105A) MOSFETs for the VCore & SOC. The Vcc GT and Vcc AUX MOSFETs are spec’d at 60A & 70A respectively.

As you can see, the VRMs are getting ample cooling from the Composite VRM heatsink that is both beefy in terms of size and features active cooling too. This motherboard is designed specifically for enthusiasts and overclocking so expect a smooth & stable operation of the electrical circuitry when this board is running. The motherboard also comes with a backplate that features thermal pads for extra cooling performance.

The CPU is supplied power through an 8+8 pin power connector configuration. This will feed the CPU with up to 300 Watts of power. The AMD Ryzen 7000 CPUs are very power-hungry with the maximum package power rating of 230W &  more if you are planning to overclock these chips.

Getting a closer look at the VRM heatsinks reveals an aluminum fin design on both heatsinks. Each heatsink has thermal pads located underneath for efficient transfer of heat.

There’s a large heat pipe that runs all the way from the top most heatsink to the PCH heatsink and is very bulky in design.

Expansion slots include two PCI Express x16 (1 x Gen 5.0 x16 or 2 x Gen 5.0 x8) and four M.2 slots.

ASRock is using a metallic cover on the sides of the expansion slots which provides protection to some extent. It adds more retention and shearing resistance by reinforcing the slots with metal plates. Aside from adding more protection, they do look really sweet.

All four M.2 slots are cooled off by the thermal pad and aluminum baseplate cooling. This will ensure stable operation for M.2 storage devices. The thermal adhesive has a plastic cover over them which needs to be removed before being used with the storage devices.

The topmost M.2 slot will house the primary PCI Gen 5.0 M.2 at the top which offers even more cooling performance through a larger heat sink. Following is the M.2 config on the motherboard:

CPU:

– 1 x Blazing M.2 Socket (M2_1, Key M), supports type 2280 PCIe Gen5x4 (128 Gb/s) mode

Chipset:

– 1 x Hyper M.2 Socket (M2_2, Key M), supports type 2230/2242/2260/2280/22110 SATA3 6.0 Gb/s & PCIe Gen4x4 (64 Gb/s) modes
– 1 x Hyper M.2 Socket (M2_3, Key M), supports type 2280 PCIe Gen4x4 (64 Gb/s) mode
– 1 x Hyper M.2 Socket (M2_4, Key M), supports type 2280 PCIe Gen4x4 (64 Gb/s) mode
– 4 x SATA3 6.0 Gb/s Connectors

The X670 dual PCHs are housed beneath a large heatsink with the Taichi eagle logo etched over it that looks great.

The PCH heat sink and the I/O cover feature RGB LEDs, as a part of the Polychrome Sync suite, embedded within it and there is also a wide range of RGB connectors on the motherboard if you want to set up your own lighting.

Storage options include eight SATA III ports rated to operate at 6 GB/s. These can support 8 different storage devices at once. There are also three USB 3.2 front panel connectors (1 x Gen 2×2 + 2 x Gen 1). USB 2.0 dual connectors are also included.

ASRock is using a Realtek ALC4082 Audio Codec for audio output through a 5.1 channel HD audio jack that comes with WIMA audio capacitors (front outputs) and an ESS SABRE9218 DAC (front panel).

The LED DEBUG along with the Power On/Off and Reset switches can be found below the PCH heat sink.

The full list of connectors on the motherboard is listed as follows.

– 1 x Power LED and Speaker Header
– 1 x RGB LED Header
– 3 x Addressable LED Headers
– 1 x CPU Fan Connector (4-pin)
– 1 x CPU/Water Pump Fan Connector (4-pin) (Smart Fan Speed Control)
