ASUS’s new flagship ROG GeForce RTX 5090D Astral graphics card has been used to break some new 3DMark world records, overclocked to 3.4GHz under LN2 cooling, using close to 1000W of power.

The achievement was done by ASUS China boss Tony Yu, using the ASUS ROG GeForce RTX 5090D Astral graphics card, tearing down the flagship China-exclusive card revealing the Blackwell GB202 GPU and GDDR7 memory chips underneath. I’m a huge fan of die shots, so let’s dive right into it.
NVIDIA’s new Blackwell GB202 GPU is fabbed on the TSMC 4nm process node, with up to 92 billion transistors, 4000 AI TOPs, 380 RT TFLOPs, 125 TFLOPS of FP32 compute, and the fastest GDDR7 memory interface with up to 1.8TB/sec memory bandwidth in stock form with the RTX 5090.
NVIDIA’s move to new GDDR7 memory is a massive upgrade over GDDR6X (and GDDR6 non-X) with twice the bandwidth and data rate of G6 memory, with higher frequencies and lower power consumption. GDDR7 memory supports PAM4 signaling and the PCB materials on the new GeForce RTX 50 series GPUs are top-of-the-line from an engineering perspective.
The new NVIDIA Blackwell GB202 GPU measures in at 922mm2 which is a 21% increase in die size based on the same node, with the larger die explaining why we’re seeing higher costs on the ultra-enthusiast GeForce RTX 5090 graphics cards. We could expect an RTX 5090 Ti or TITAN RTX graphics card, which is something I absolutely, definitely need to see.
