The company told Tweaktown that the blocks required some modification because AMD's new Radeon RX 7900 series graphics cards include special memory cache dies (MCDs) next to the main chip. This meant the MCDs, as well as the regular GPU components (the VRMs, VRAM, Voltage Controllers, and the chip die) were in a different place.

AMD's use of TSMC's new 5nm process node for its GCD, which pushes for up to 54 per cent more performance per watt, and that even if the GPU is efficient the power consumption is higher than the previous-gen RDNA 2-based GPUs.

It said that AMD is sucking up to 355W of total board power for its flagship Radeon RX 7900 XTX graphics card and has put it into its smallest package ever: 300mm² GCD that contains 165 per cent more transistors per mm² than the previous generation.

The EK-Quantum Vector² RX 7900 XTX D-RGB itself, it's the first Vector² water block for Radeon GPUs. It uses the Vector² series water block teamed with a black-anodised aluminum backplate, all in the same package.

The cooling engine has been rotated by 90 degrees so that the fins are perpendicular to the die. EK explains that for optimal delta, the coolant flows over the graphics core die (GCD) first, and the memory cache dies (MCD) afterwards.

You can pre-order the new EK-Quantum Vector² RX 7900 XTX D-RGB water blocks right now through the UK Webshop and Partner resellers, while they'll actually ship out to customers in early December. It will set you back about $240 USD.
