Lenovo Legion Tower 5 Gen 8 (R7 7700 / RTX 4070 Super / 16GB RAM / 1TB SSD)

Manufacturer: Lenovo

The Lenovo Legion Tower 5 Gen 8 is a desktop gaming PC that combines AMD's 8-core Ryzen 7 7700 processor with NVIDIA's RTX 4070 Super graphics card in an ATX form factor measuring 425 mm tall, 396 mm wide, and 205 mm deep. The system ships with 16GB of DDR5 RAM running at 5200 MHz across two memory slots, paired with a 1TB NVMe SSD for storage. Wireless connectivity is handled by Wi-Fi 6E with backward compatibility for older standards, and Bluetooth 5.1 covers wireless peripheral use alongside a single RJ45 port for wired networking.

The R7 7700 is an 8-core, 16-thread desktop processor with an unlocked multiplier, a base clock of 3.8 GHz, and a turbo clock reaching 5.3 GHz, supported by 512 KB of L1 cache, 8 MB of L2 cache, and 32 MB of L3 cache. It sits in an AM5 socket and is compatible with X670, B650, X870, B840, and B850 chipsets, with the platform supporting up to 128GB of RAM. The RTX 4070 Super is built on NVIDIA's Ada Lovelace architecture at a 5 nm process node, featuring 12GB of GDDR6X memory on a 192-bit bus, up to 504.2 GB/s of bandwidth, and 35.48 TFLOPS of floating-point performance with a turbo clock of 2,480 MHz. It supports DirectX 12 Ultimate, ray tracing, DLSS, and stereoscopic 3D, and can drive up to four displays through three DisplayPort outputs and one HDMI 2.1 port. Benchmark results include a PassMark score of 34,473 and a Geekbench 6 multi-core result of 14,920.

Pros
  • The R7 7700's unlocked multiplier gives users the option to overclock the processor, a flexibility reflected in the near-identical standard and overclocked PassMark scores
  • The RTX 4070 Super supports ray tracing, DLSS, and DirectX 12 Ultimate, covering the full set of modern rendering features for compatible games
  • Wi-Fi 6E support with backward compatibility across Wi-Fi 6, 5, and 4 ensures fast wireless connectivity with broad compatibility for existing network equipment
  • The USB port selection is well-rounded, including four USB-A Gen 1 ports, two USB-A Gen 2 ports, and two USB-C Gen 2 ports, offering good variety for peripherals
  • The platform supports up to 128GB of DDR5 RAM, leaving significant headroom for memory expansion beyond the current 16GB configuration
  • Integrated graphics are present on the CPU, providing a fallback display output path independent of the discrete GPU
Cons
  • The system ships with only 16GB of DDR5 RAM across two slots, which may feel limiting for memory-intensive workloads without an upgrade
  • The RTX 4070 Super's 12GB of GDDR6X on a 192-bit bus may constrain performance at very high resolutions or with large texture workloads
  • Air-water cooling is absent, which may be a concern given the 220W TDP under sustained loads
  • There is no S/PDIF output, limiting audio connectivity options for users with digital audio equipment that requires it
  • No Thunderbolt 3 or Thunderbolt 4 ports are present, ruling out high-bandwidth docking solutions and external GPU enclosures that rely on those interfaces
Who is this for?

The Lenovo Legion Tower 5 Gen 8 is a good fit for users focused on gaming at 1080p and 1440p resolutions, where the RTX 4070 Super's ray tracing, DLSS, and DirectX 12 Ultimate support translate directly into a capable modern gaming experience. The R7 7700's unlocked multiplier also makes it appealing to users who want to explore CPU overclocking without needing a separate platform upgrade. With the AM5 socket supporting up to 128GB of DDR5 RAM and compatibility across multiple chipsets, it also suits users planning a long upgrade cycle who want a system that can grow with their needs over time, and the broad USB port selection across Gen 1 and Gen 2 standards covers most everyday peripheral setups comfortably.

Who is this NOT for?

Users who regularly work with large GPU-accelerated datasets, high-resolution video production, or texture-heavy rendering pipelines may find the 12GB VRAM on a 192-bit bus a limiting factor under sustained professional workloads. The system ships with only 16GB of DDR5 RAM, which leaves little breathing room for heavily multithreaded creative tasks without an immediate memory upgrade. Those who rely on Thunderbolt-based peripherals, external GPU enclosures, or high-bandwidth docking stations will also find no suitable ports available, and users with digital audio setups requiring an S/PDIF output will need to look elsewhere or add a separate audio solution.
