No Chiplets, GeForce RTX 5090 to Feature Massive Monolithic Blackwell GPU

Based on what we know so far, the NVIDIA GB202 “Blackwell” GPU will power the flagship GeForce RTX 5090 graphics card. Preliminary specifications have revealed details about the presence of 192 SMs, which will contain up to 24,567 CUDA cores if the chip retains the SM unit design from the current AD102 “Ada” generation processors.

Now, based on a new tweet from the well-informed insider Kopite7kimi, it has been revealed that the GPU will use a monolithic core design instead of chiplet technology. It is somewhat surprising that NVIDIA has moved to using chiplet technology in its advanced processors for HPC/AI infrastructure, such as the B100 and B200.

However, it appears that NVIDIA still wants to retain monolithic cores for its GPU chips intended for individual users in the gaming PC market. It is said that the GB202 “Blackwell” GPU will use a physically monolithic design, and from earlier reports, we know that it is expected to have double the number of SM clusters and execution cores compared to the GB203 version in the GeForce RTX 5080 model.

This will create a significant performance gap between the two cards, but the RTX 5090 is being designed as a gaming "beast" from the start. However, a monolithic chip design with such a high number of transistors raises concerns about power consumption and heating.

We will soon have more information about the NVIDIA GeForce RTX 5090, but before that, let's delve a bit more into the GB202 “Blackwell” graphics processor itself. So, it seems we are looking at a monolithic design, but we cannot entirely rule out earlier announcements or the possibility of a chiplet-style design.

GeForce RTX 5090 Will Be an Unprecedentedly Powerful Gaming Graphics Card

NVIDIA could essentially pack two GB203 cores into what appears to be a large monolithic silicon package, without it looking like chiplet topology, at least not at first glance.

This will allow for better communication between cores and will not have the communication bottlenecks associated with chiplet technology. Although NVIDIA has solutions for overcoming bottlenecks using the fast NVLINK bus and other advanced interconnection technologies, their implementation could be more expensive and could lead to a price increase for graphics cards as it increases the complexity of the graphics processor's construction.

NVIDIA already has a solution that uses chiplet topology in the form of complex GPU solutions that have already hit the market, such as the GA100 and GH100.

These AI processors essentially use two smaller cores connected by interconnection and sharing L2 cache memory.

Unmatched Gaming Performance

Brian Catanzaro from NVIDIA explained that this type of implementation improves the scalability of solutions and that their initial transition to this design went smoothly.

It is also expected that the chip will be based on TSMC's N4P (5nm) manufacturing technology with better transistor packing density, by about 30%, which should bring a nice performance improvement along with the upgrade in the form of a new microprocessor architecture.

In addition to everything previously mentioned regarding the core of the future graphics processor, the NVIDIA GeForce RTX 5090 graphics card will now certainly use a 512-bit memory interface on the fastest models of the next generation, and there are already reports of a completely new cooling system and a new PCB design specifically designed for this monster of a card.

Considering the information suggesting that AMD is pulling out of the ultra-high-end segment of graphic performance with its future RDNA 4 line, it seems that NVIDIA could further increase its advantage in the segment of ultimate gaming performance with the Blackwell GPU generation.

The NVIDIA GeForce RTX 5090 is expected to launch a few weeks apart from the RTX 5080, which is claimed to be the first Blackwell GPU for gaming users to hit store shelves, according to wccftech. As technology advances, competition between major graphics card manufacturers intensifies.

NVIDIA's approach with the GeForce RTX 5090 marks its determination to lead the market, especially as it moves away from chiplet technology for its gaming GPUs. The choice of a monolithic design for the RTX 5090 suggests a strategic decision aimed at optimizing performance and simplifying the GPU architecture.

However, this decision is not without potential drawbacks. Looking ahead, the launch of the RTX 5090 will be closely watched by both industry analysts and consumers. The card’s performance, pricing, and reception will provide valuable insights into the future direction of GPU development.

NVIDIA GeForce RTX 5090 represents a significant milestone in GPU development, blending cutting-edge technology with strategic design choices to deliver unparalleled gaming performance. Although the price is relatively high, you will not find a more capable graphics card on the market.
