Yeyian Phoenix (i9-14900KF / 4070 Super / 32GB RAM / 1TB SSD)

Manufacturer: Yeyian

The Yeyian Phoenix (i9-14900KF / 4070 Super / 32GB RAM / 1TB SSD) is an ATX-form-factor desktop gaming PC built around Intel's Core i9-14900KF processor and NVIDIA's GeForce RTX 4070 Super graphics card. The system ships with 32GB of DDR5 memory running at 5600 MHz, paired with a 1TB NVMe SSD for storage. It carries a two-year warranty and is designed to fit standard ATX enclosures, with a chassis measuring 556 mm in height and 305 mm in width.

On the graphics side, the RTX 4070 Super is built on NVIDIA's Ada Lovelace architecture using a 5 nm process node, offering 35.48 TFLOPS of floating-point performance alongside 12GB of GDDR6X memory across a 192-bit bus with up to 504.2 GB/s of memory bandwidth. The GPU supports DirectX 12 Ultimate, ray tracing, and DLSS, and can drive up to four displays simultaneously via one HDMI 2.1a port and three DisplayPort outputs. The i9-14900KF CPU provides 32 threads with a turbo clock speed reaching 6 GHz, an unlocked multiplier, and recorded benchmark scores of 20,578 in Geekbench 6 multi-core and 58,366 in PassMark. Connectivity includes Wi-Fi 6E, Bluetooth 5.3, a single RJ45 port, and an extensive USB layout spanning USB 2.0, USB 3.2 Gen 1, USB 3.2 Gen 2, and USB 3.2 Gen 2x2 ports in both Type-A and Type-C form factors.

Pros
  • The GPU delivers 35.48 TFLOPS of floating-point performance with support for ray tracing and DLSS, backed by 12GB of GDDR6X VRAM and 504.2 GB/s of memory bandwidth
  • The CPU supports 32 threads with a turbo clock reaching 6 GHz, an unlocked multiplier, and big.LITTLE technology for flexible workload distribution
  • Wi-Fi 6E support alongside Bluetooth 5.3 provides fast and modern wireless connectivity out of the box
  • The USB port selection is extensive, covering USB 2.0, USB 3.2 Gen 1, Gen 2, and Gen 2x2 in both Type-A and Type-C configurations
  • Memory is expandable up to 192GB across two channels with ECC support and a maximum rated speed of 5,600 MHz
  • The system includes Intel Resizable BAR and a PCIe 4 interface, ensuring the GPU can take full advantage of available bandwidth
Cons
  • The chassis is large at 556 mm tall and 305 mm wide, which may be difficult to fit in space-constrained setups
  • There are no Thunderbolt 3 or Thunderbolt 4 ports, limiting high-speed peripheral and daisy-chain display options
  • No USB 4 ports are present, which restricts top-end wired transfer speeds compared to newer port standards
  • Air or water cooling is not included, meaning thermal management of the 220W TDP processor relies on a separate solution
  • The GPU does not feature RGB lighting, which may matter to users building a visually coordinated system
Who is this for?

This system is well suited to users who engage in demanding gaming workloads, where the combination of a high-thread-count processor with a 6 GHz turbo ceiling and a GPU delivering 35.48 TFLOPS with ray tracing and DLSS support translates into sustained rendering capability. Content creators and enthusiasts running multithreaded applications such as video encoding or 3D rendering will benefit from the 32-thread CPU, 32 MB L2 and 36 MB L3 cache, and DDR5 memory running at 5,600 MHz. The system also fits well in a dedicated desktop workstation environment where the ATX form factor, ECC memory support, expandability up to 192GB RAM, and broad chipset compatibility with Z790 and related platforms allow for a stable and configurable long-term setup.

Who is this NOT for?

Users who require a compact or space-efficient build will find the 556 mm tall ATX chassis impractical, as it demands a full-sized case and considerable desk or floor space. The absence of Thunderbolt ports and USB 4 connectivity makes this a poor fit for professionals who rely on high-bandwidth peripheral ecosystems, such as those using external GPU enclosures, high-speed NAS devices, or daisy-chained displays via Thunderbolt. Additionally, users who need a portable or relocatable workstation will be deterred by the desktop-only form factor and the 220W CPU TDP, which ties the system firmly to a fixed, well-ventilated environment.
