The Knockout is built on an AMD Ryzen 7 9850X3D processor with 8 cores and 16 threads, an NVIDIA GeForce RTX 5080 16GB GDDR7 graphics card, 32GB of DDR5 6000MHz memory and a 2TB WD Blue SN5100 M.2 PCIe 4.0 NVMe SSD. It is cooled by a 240mm MSI MAG CORELIQUID A13 liquid cooler and powered by a Contour 850W ATX 3.1 PSU. It comes with Microsoft Windows 11 Home 64-bit (genuine, pre-installed) and a 3-year parts and labour warranty.

Processor: AMD Ryzen 7 9850X3D

The AMD Ryzen 7 9850X3D is an 8 core, 16 thread processor for the AM5 socket, with a 4.7GHz base clock and a maximum turbo of 5.6GHz. It carries 96MB of L3 cache, which is the kind of large cache that gaming workloads make good use of. Eight fast cores are well matched to current games, and the 16 threads leave headroom for streaming software, voice chat and background tasks running alongside a game. The processor also includes integrated graphics, although the RTX 5080 handles all display duties in this build.

Graphics: NVIDIA GeForce RTX 5080 16GB

The NVIDIA GeForce RTX 5080 has 10752 cores and 16GB of GDDR7 memory, and it is the graphics card that makes the Knockout a 4K machine. It sits in the flagship tier, aimed at 4K ultra settings, and it also suits high-resolution creative work such as GPU rendering in Blender and accelerated video editing. The card provides 3 x DisplayPort 2.1b and 1 x HDMI 2.1b outputs and supports up to 4 monitors at once. The exact output layout may vary by card brand.

Memory and storage

The 32GB of Kingston Fury Beast RGB DDR5 runs at 6000MHz with CL36 timings, fitted as two 16GB modules in dual channel. The Gigabyte B650 EAGLE AX motherboard has four DIMM slots with two in use and supports up to 192GB, so there is plenty of room to add memory later. The 2TB WD Blue SN5100 M.2 PCIe 4.0 NVMe SSD is rated at 7100MB/s read and 6700MB/s write and holds Windows, your applications and a large game library. The motherboard offers three M.2 slots (one PCIe 5.0 and two PCIe 4.0), of which two are free. It also has four SATA 6Gb/s ports, all unused, and the case has mounts for two 3.5in and three 2.5in drives.

Case and cooling

The Phanteks XT View is a black mid tower with tempered glass on the front and side, so the components are on show. It ships with three pre-installed 120mm ARGB fans, one at the rear and two on the side. The processor is cooled by the MSI MAG CORELIQUID A13 Black 240mm AIO liquid cooler, which keeps the Ryzen 7 9850X3D at a sustained boost under load. Power comes from a Contour 850W ATX 3.1 PSU, which is non-modular. The case measures 440mm deep, 230mm wide and 500mm high, and there is no optical drive fitted.

Connectivity

The AMD B650 chipset board provides a 1GbE Realtek LAN port, built-in Wi-Fi 6E and Bluetooth 5.0, and Realtek 7.1 HD Audio. At the rear there are 2 x Type-A 10Gbps ports, 1 x Type-C 5Gbps port and 6 x USB 2.0 ports, along with the Ethernet port. The front panel adds 1 x USB 3.0, 1 x USB 3.2 Type-C and a headphone and microphone combo jack. For expansion, the primary PCIe 4.0 x16 slot is taken by the graphics card, and three further PCIe 3.0 slots run at x1 for add-in cards such as capture or network adapters.

The AMD Ryzen 9 with RTX 5080 Gaming PC uses a 12 core Ryzen 9 7900X with the same RTX 5080 16GB, 32GB of DDR5 6000MHz and a 1TB SSD, so it suits buyers who want the same graphics card with a different processor. The V-Ray / 3ds Max Workstation – Ryzen 7 9700X / RTX 5070 Ti is a step down in graphics and is aimed at rendering, with 64GB of memory.
