Size, Weight, and Lighting Comparison
Physical Dimensions
The YXHGeeek RTX 4090 AMP Copper block measures 11.2 inches in length, 6.2 inches in width, and 1 inch in height. The YXHGeeek Gigabyte RTX 4090 Copper block is more compact, with a length of 9 inches, a width of 6.5 inches, and a height of 0.8 inches. The AMP model extends further along the card, which may affect clearance for nearby components or radiator mounting positions. The Gigabyte model is shorter and slightly taller, offering a different profile. You should measure your specific graphics card layout and surrounding case space to ensure the chosen block fits without interference. The dimensional differences are significant enough to impact your cooling loop design and component placement.
Block Weight
Both water blocks share the exact same weight specification of 3.53 ounces. This identical mass means that neither block places more strain on your graphics card’s PCB or mounting brackets than the other. The manufacturer uses large area hollowing out in the copper plate to achieve this lightweight design, which helps protect the PCB from deformation. Since the weight is equal, you do not need to worry about one option being heavier or more likely to cause sagging due to mass alone. Your mounting solution will need to support this specific weight regardless of which model you select.
ARGB Lighting
Both products feature ARGB lighting capabilities, allowing you to sync colors with your system’s motherboard software. The YXHGeeek RTX 4090 AMP Copper block lists ARGB in its attributes, while the YXHGeeek Gigabyte RTX 4090 Copper block specifies 5V ARGB in its key specs. Standard ARGB headers typically operate on 5V, so both blocks are likely compatible with standard 5V 3-pin motherboard headers. However, the Gigabyte model explicitly confirms the 5V requirement, which provides clarity for your setup. You should verify your motherboard header voltage to ensure safe operation, though both are designed for standard addressable RGB integration.
Construction Material
Both blocks are constructed primarily from copper, which is the standard material for high-performance water cooling due to its excellent thermal conductivity. The YXHGeeek RTX 4090 AMP Copper and the YXHGeeek Gigabyte RTX 4090 Copper both utilize a 10mm thick copper plate. This thickness ensures sufficient material for heat transfer while allowing for a single-layer sealing ring design, which reduces the risk of leakage compared to thinner multi-ring structures. Both also feature surface electroplating for anti-oxidation and corrosion resistance. Since the material and thickness are identical, thermal performance potential from the base material is equal.
Internal Design
Both units employ a second-generation three-layer structure design intended to increase water flow coverage area and improve heat dissipation efficiency. The copper plate in each block is integrated with high-precision CNC processing to create a large water flow coverage area. The cavity design undergoes scientific fluid analysis to eliminate dead angles, ensuring effective cooling for the GPU core, VRAM, and power supply MOS. The height of positioning columns is optimized in both models to strictly fit the required heat dissipation components. Since the internal design philosophy and manufacturing techniques are described identically, you can expect similar flow dynamics and coverage.
Which block fits your build?
Zotac RTX 4090 AMP owners
This block is designed specifically for the Zotac GeForce RTX 4090 AMP. You need this exact fit to ensure the positioning columns align correctly with your card's GPU core, VRAM, and MOS components. The 11.2-inch length covers the necessary area for your specific PCB layout.
Gigabyte RTX 4090 owners
This unit matches the Gigabyte GeForce RTX 4090 form factor. Its 9-inch length and 0.8-inch height make it more compact than the alternative. You get the same 10mm copper plate and ARGB lighting, but with dimensions tailored to fit your Gigabyte card without interference.
Builders needing lower profile
If your case has height restrictions, this block is the better choice. It stands 0.8 inches tall, compared to the 1-inch height of the Zotac-specific model. Both weigh the same at 3.53 ounces, but the reduced height helps ensure clearance for surrounding components in tight builds.
