We’re just weeks away from the launch of NVIDIA’s next-generation GeForce RTX 5090. There have been many leaks, but now it’s time to take a look at the PCB of one of the custom RTX 5090 graphics cards.

Chiphell’s new post features a beautiful and large PCB with over 40 capacitors and 16 GDDR7 memory modules. The PCB we’re considering is for a custom AIB model of the GeForce RTX 5090, and since there’s no NVIDIA branding on the PCB itself, this is a custom AIB card, not a Founders Edition or NVIDIA reference model.
We’ve seen leaks of the GDDR7 memory layout, and this new PCB leak is consistent with that, with 16 modules total, 5 modules on each side (4 on top, 2 below the GPU), and looks delicious. Configurations are possible: 32GB, 2GB, 3GB, or 4GB, depending on whether GDDR7 memory modules are used, 48GB or even 64GB It will be.
The new custom GeForce RTX 5090 graphics card and its leaked PCB also show off a new PCIe 5.0 interface, which is an upgrade from the RTX 40 series GPU’s PCIe 4.0 interface. The GB202 GPU size, GDDR7 memory layout, and PCIe slots match previous leaks… which means the GeForce RTX 5090 is inching closer to its big reveal at CES 2025.
NVIDIA GeForce RTX 5090 details so far:
Huge GB202 GPU + PCB Leak: Recent leaks reveal a huge GB202, 16 ultra-fast GDDR7 memory modules, and a new PCIe 5.0 interface.
20,000+ CUDA Cores: With a rumored 21,760 CUDA cores, we’re looking at a significant upgrade over the 16,384 inside the RTX 4090. In addition to more CUDA cores, it also adds Blackwell GPU architecture cores that are an upgrade over the current Ada Lovelace GPU cores under the hood. RTX4090.
32GB of next-generation GDDR7 memory: NVIDIA is the first to use the ultra-fast GDDR7 memory standard, and the flagship GeForce RTX 5090 comes with an incredible 32GB of GDDR7 memory. This is another big upgrade over the RTX 4090, which comes with 24 GB of GDDR6X memory.
Up to 2.0TB/s Memory Bandwidth: The RTX 5090 features a monster 512-bit memory bus, allowing for insane memory bandwidth limits of up to 2.0TB/s when the RTX 5090 uses 32Gbps GDDR7 memory I heard it will be. module. By comparison, it’s another huge upgrade over the RTX 4090 with 1.0TB/s of memory bandwidth.
600W Power: Another big upgrade to the RTX 5090 is the 600W power. This is an additional 150W of power on top of the RTX 4090’s 450W TDP. We’ve seen custom models and overclocked RTX 4090 cards reaching up to over 600W of power. , but the RTX 5090 will be on another level again on top of that. We hope to see a 600W+++ custom AIB model of RTX 5090.
4K Performance: NVIDIA’s next-generation ultimate gaming GPU in the GeForce RTX 5090 features 50-70% higher overall performance compared to the RTX 4090, especially at high-end 4K resolutions. 4K 120FPS gaming should be even easier to achieve on the RTX 5090 than the RTX 4090. With 4K 240FPS coming this year and in 2025, the RTX 5090 will be the perfect GPU for upcoming 4K 240FPS gaming. future.
RT Performance: The biggest performance improvement for the next-generation Blackwell-based GeForce RTX 50 Series GPUs is ray tracing. Using RT, you can expect a fairly large 2-3x performance improvement. For RTX 5090 and RTX 5080, this can be more than 4x in some cases compared to their RTX 40 series counterparts. Put the new DLSS 4 on top of that and you’ll get incredible RT performance.
DLSS 4: This is probably my personal favorite part of the excitement for NVIDIA’s next generation GPUs. AI-powered upscaling with next-generation DLSS 4, running only on new Blackwell-based RTX 50 series GPUs. You can expect even higher image quality than offered by DLSS 3.x and new levels of performance with DLSS 4 enabled on new RTX 5090 or RTX 5080 graphics cards.
Power efficiency: NVIDIA’s current generation GeForce RTX 4090 can use 450W to 600W of power depending on model and overclocking, but the new GeForce RTX 50 series GPUs are much higher than the leading RTX 4090 and RTX Provides performance per watt. 4080 SUPER graphics card. Another exciting part that will be unraveled in the near future.
