Let’s dive into the exciting world of NVIDIA’s upcoming RTX 50 mobility GPUs. These graphics cards promise impressive performance and memory configurations, and they’re sure to make waves in the gaming and content creation communities.

NVIDIA RTX 5090, 5080 & 5070/Ti Mobile: 16GB VRAM via a 256-bit Bus

According to recent leaks from “Moore’s Law is Dead,” NVIDIA’s top-end Blackwell laptop GPUs are set to feature 16GB of memory across a 256-bit bus. Let’s break down what this means for each GPU:

  1. RTX 5090: This beastly mobile GPU will pack 16GB of GDDR6 memory on a 256-bit bus. It’s expected to be a powerhouse, offering excellent performance for gaming, rendering, and other demanding tasks.

  2. RTX 5080: Like its big brother, the RTX 5080 will also feature 16GB of memory but with the same 256-bit bus. It’s rumored to be faster than the RTX 4090 in ray-traced gaming, making it an exciting choice for gamers and creators alike.

  3. RTX 5070/Ti Mobile: This GPU will also sport 16GB of memory but with a 128-bit bus. While not as wide as the 256-bit bus, it’s still a solid configuration for a mid-range mobile GPU.

What About the RTX 4090, 4080, and 4070?

For comparison, the previous generation RTX 40 series mobile GPUs had the following memory configurations:

  • RTX 4090: 16GB (256-bit)
  • RTX 4080: 12GB (192-bit)
  • RTX 4070: 8GB (128-bit)

The move to 16GB across the board for the RTX 50 series is a welcome upgrade, especially for memory-intensive tasks like high-resolution gaming and video editing.

The GB203 Die and GDDR7 Memory

The RTX 5080 and 5090 will be based on the GB203 die. Interestingly, these GPUs are rumored to feature GDDR7 memory and support for PCIe Gen 5. Expect memory clocks in the range of 24-28Gbps, although mobile variants will likely run at slightly lower frequencies than their desktop counterparts.

Performance Expectations

The RTX 5090 is projected to be 70-80% faster than the RTX 4090, thanks to its massive core count and upgraded memory. With over 20,000 cores, it’s poised to deliver exceptional performance in both gaming and professional workloads.

In summary, NVIDIA’s RTX 50 series mobile GPUs are shaping up to be a game-changer. Whether you’re a gamer, content creator, or both, these GPUs promise to deliver the performance and memory capacity needed for the most demanding tasks. Keep an eye out for their official release later this year! 🚀🎮
