Manli GeForce RTX 3050 (M2587+N739)

Manufacturer: Manli

The Manli GeForce RTX 3050 (M2587+N739) is a discrete graphics card built around Nvidia's Ampere architecture, designed with a low-profile form factor measuring 162 mm wide and just 71 mm tall. This makes it one of the more physically constrained options in the discrete GPU space, well-suited to slim desktop cases and compact enclosures that cannot accommodate standard-height cards. It operates at a 70W thermal design power and uses air cooling exclusively, connecting to the host system via PCIe 4.0.

The card's GPU runs at a base clock of 1042 MHz with a turbo frequency of 1470 MHz, backed by 2304 shading units, 72 texture mapping units, and 32 render output units — producing 6.774 TFLOPS of floating-point performance. Its 6GB of GDDR6 VRAM operates at an effective 14000 MHz across a 96-bit bus for up to 168 GB/s of bandwidth, with ECC memory support included. The feature set covers DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, DLSS, stereoscopic 3D, multi-display support for up to two outputs via one HDMI 2.1 and one DisplayPort, and Intel Resizable BAR, while XeSS, LHR, and RGB lighting are not present.

Pros
  • The 162 mm x 71 mm low-profile form factor enables installation in slim desktop cases and compact enclosures that cannot fit standard-height graphics cards
  • A 70W TDP makes the card compatible with systems that have limited power supply headroom or restricted thermal budgets
  • Support for ray tracing and DLSS brings hardware-accelerated lighting and AI-based upscaling to a physically small card
  • ECC memory support provides error detection and correction, which is useful in compute-adjacent workloads where data accuracy is important
  • Intel Resizable BAR support enables the CPU to access the full GPU frame buffer at once, improving memory transfer efficiency
Cons
  • The 96-bit memory bus limits maximum bandwidth to 168 GB/s, which can constrain performance in memory-intensive rendering scenarios
  • 6GB of VRAM sets a firm upper bound on the card's capacity for higher-resolution textures and larger frame buffers
  • Only two video outputs are available — one HDMI 2.1 and one DisplayPort — restricting multi-monitor setups to two screens
  • Liquid and hybrid cooling are not supported, leaving air cooling as the only thermal management option
  • XeSS (XMX) and RGB lighting are absent, limiting feature breadth for users who rely on or prefer those capabilities
Who is this for?

This card is a natural fit for users assembling systems in slim or compact enclosures where the 162 mm x 71 mm low-profile dimensions are a hard requirement rather than a preference. Its 70W TDP also suits builds where power delivery is constrained, removing the need for high-capacity PSUs or additional power connectors. Users who want access to a current-generation feature set — including ray tracing, DLSS, and DirectX 12 Ultimate — within those physical and power boundaries will find the card's specification coherent and complete. The presence of ECC memory support also extends its relevance to light compute tasks where data reliability is a practical consideration.

Who is this NOT for?

Users targeting demanding graphical workloads or higher display resolutions will quickly encounter the limitations imposed by the 6GB GDDR6 frame buffer and 96-bit memory bus, both of which constrain the card's throughput and capacity under sustained load. The card is equally unsuitable for anyone who needs more than two simultaneous display outputs, as the single HDMI 2.1 and single DisplayPort configuration caps multi-monitor configurations at two screens. Those who require liquid or hybrid cooling for quieter operation or tighter thermal management will also find no support for it here, since the card is limited to air cooling only.

The card carries 6GB of GDDR6 VRAM running at an effective speed of 14000 MHz through a 96-bit memory bus, resulting in a maximum bandwidth of 168 GB/s. The 96-bit bus width is a defining structural characteristic that places a firm ceiling on available memory throughput. ECC memory support is included, providing error detection and correction functionality for workloads where data integrity is a practical concern.

On the software and API side, the card supports DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 3, providing broad coverage across graphics and general-purpose compute workloads. Ray tracing and DLSS are both present, enabling hardware-accelerated lighting and AI-driven upscaling, while stereoscopic 3D and multi-display technology extend its output capabilities further. Intel Resizable BAR is supported for more efficient CPU-to-GPU memory access. XeSS (XMX), LHR, and RGB lighting are all absent from this card's specification.

Ports:

HDMI ports 1
HDMI version HDMI 2.1
DisplayPort outputs 1
USB-C ports 0
DVI outputs 0
mini DisplayPort outputs 0

The card offers two video outputs: one HDMI 2.1 port and one DisplayPort, covering the two primary modern display interfaces. There are no DVI, USB-C, or mini DisplayPort connections present, keeping the output configuration minimal and focused entirely on current-generation connectivity standards.

General info:

GPU architecture Ampere
Thermal Design Power (TDP) 70W
PCI Express (PCIe) version 4
semiconductor size 8 nm
number of transistors 8700 million
Has air-water cooling ✕
width 162 mm
height 71 mm

Built on the Ampere architecture and fabricated on an 8 nm process node with 8700 million transistors, this card connects to the motherboard via PCIe 4.0. Its 70W thermal design power rating reflects a low-draw design, and cooling is handled solely by air — no liquid or hybrid cooling option is available. The physical dimensions of 162 mm wide and 71 mm tall place it firmly in low-profile territory, making it compatible with slim and compact enclosures where standard-height cards would not fit.

Final Verdict

The Manli GeForce RTX 3050 (M2587+N739) is a card that knows its role and fulfills it with a well-matched set of specifications. Its defining characteristic is the low-profile 162 mm x 71 mm form factor paired with a 70W TDP, which together make it one of the few discrete GPU options that can realistically slot into slim desktop builds without compromise on power or space. The inclusion of ray tracing, DLSS, DirectX 12 Ultimate, and ECC memory support means users are not sacrificing feature coverage to achieve that compact footprint. Where the card asks for patience is in its memory configuration — the 6GB GDDR6 frame buffer and 96-bit bus set a clear ceiling on sustained performance under heavier workloads. For users whose primary constraint is physical space or system power draw, this card delivers a coherent and genuinely useful solution; for those prioritizing raw throughput or extensive multi-display setups, its architectural boundaries will become apparent.
