yesterdaya user at Chiphell shared an image of what is claimed to be an RTX 5090 exposed PCB, which has 16 pads laid out for VRAM and a large area for the GPU packaging. Today, that same PCB houses the GB202-300-A1 GPU die, 32GB of GDDR7 memory, and all surrounding capacitors, inductors, and MOSFETs (Baidu through spring breeze). The GPU is marked as a qualification sample, so it may be used for validation testing. Commercial samples should come with retail-grade chips, although we suspect there will be significant differences between them.
The white text on the GPU looks rather unusual, although it does line up with some of the RTX 4090 qualifying samples we’ve seen in the wild before. Still, take this leak with a grain of salt as the official reveal is still about 10 days away.
Leaked images show off the RTX 5090 in all its glory. The GB202 chip powering the RTX 5090 is rumored to be Nvidia’s largest consumer GPU since 2018. 744 square millimeters. Some quick measurements spring breeze Recommended GPU package size (including metal frame) is approximately 64mm x 59mm, approximately 3,776 square millimeters.
Assuming our GPU is single-die, the mask limit enables a maximum die size of approximately 850 mm2. Nvidia’s GPUs are generally reserved for data centers; see B100, H100, A100, and V100 accelerators. Nvidia usually sticks to smaller die in its mainstream range, with the last exception being the 754mm² RTX 2080 Ti and the 815mm² Nvidia TITAN V, but it’s geared more towards professionals.
Back to the topic, there are 16 VRAM modules around the GB202 package, presumably 16Gb 28Gbps Died by Samsung. This gives us a total of 32GB of RAM, which can be upgraded to 48GB if Nvidia uses it 24GB Future mods.

RTX 5090 Yes rumor Featuring 21,760 CUDA cores, equivalent to 170 SMs out of 192 SMs in the full-fat GB202 configuration. So the RTX 5090 is powered by an 88% enabled die, which leaves room for a potential RTX 5090 SUPER or Ti/Tie, whatever you prefer later, but that’s just speculation. Beyond that, the rest of the Blackwell lineup looks rather unexciting, as the RTX 5080’s core count dropped by more than 50% to 84 SM, RTX 5070 Titanium to 70 SM, while the RTX 5070 only goes to 48 SM.
Nvidia is expected to debut the RTX 5090, RTX 5080 and RTX 5070 series at Blackwell. International Consumer Electronics Show Next month, according to leaks Sotech. We’ll hear more about pricing and performance directly from Jensen on January 6th.
