At this year’s GTC conference, NVIDIA unveiled the Blackwell architecture, and the new generation of compute cards based on this architecture significantly surpasses current products in AI performance. Orders are pouring in, and for consumers, the primary concern is when the GeForce graphics cards based on Blackwell will be officially released. According to previously leaked information, NVIDIA is expected to reveal more details about the gaming graphics cards during the Taipei Computer Show, with the flagship RTX 5090 receiving the most attention. Now, the PCB layout for the RTX 5090 has been exposed, densely packed with GDDR7 memory.
According to earlier leaks, the RTX 5090 graphics card will feature the latest generation of GDDR7 memory with a tighter layout, adopting a 4-5-2 design: four memory chips on top, five on each side, and two on the bottom, totaling 16 memory chips. Currently, the RTX 4090 has a 3-4-1 layout. Assuming each memory chip has a 2GB capacity, the RTX 5090 will have 32GB of memory, a 33% increase from the current 24GB.
Due to the higher density and number of memory chips, the PCB of the RTX 5090 will be more compact, resulting in increased heat generation and power consumption. To enhance cooling, the PCB of the RTX 5090 is expected to be larger, with the reference cooler potentially adding more fans. Some reports suggest that four fans will become standard for non-reference cards, which will naturally increase the size of the graphics card.
The RTX 5090 will not only have a substantial increase in CUDA cores and memory but also in memory bandwidth, potentially reaching an unprecedented 512-bit. This would make the card a true performance beast, with expected rasterization performance improvements of 60-70% and ray tracing performance doubling. Currently, even the RTX 4090 faces no competition in the graphics card market. If the RTX 5090 launches successfully, it will likely dominate the market. Despite the high price, the booming AI industry ensures that there will be no shortage of buyers for the RTX 5090.
