High-Performance GPU Cooling The new Vector² water blocks effortlessly solve the issue of excessive heat generation during high load on the GPU. These Radeon RX 7900 XTX water blocks cool the graphics compute die, voltage regulation module, voltage controllers, the VRAM, and the MCDs on the AMD Radeon RX 7900 XTX Graphic cards. The new Radeon RX 7900 XTX GPUs have GCD that is manufactured in a cutting edge 5nm process, allowing 54% improvement of performance per watt. While the GPU is efficient, it does still use more power than the previous generation. At 355W total board power that is packed in a smaller package than ever, with 300mm² GCD that contains 165% more transistors per mm² than the previous generation. Overall these GPUs feature 58 billion transistors for 61 TFLOPs of performance. What differs from all other Vector² water blocks is that the cooling engine has been rotated by 90°, so the fins are perpendicular to the die. For optimal delta, the coolant flows over the graphics core die first, and the memory cache die after. Consequently, all MCDs get the same temperature coolant.
