Nvidia’s next-generation Blackwell laptop GPU has been the subject of another leak, with the GB203 chip slated to be the engine of the desktop RTX 5080 graphics card powering the laptop RTX 5090 as well as the mobile RTX 5080.
That said, in theory, the realization of an RTX 5080 notebook would, as you might expect, significantly reduce the number of cores, but you could still get a much more powerful GPU than the RTX 4080. there is. Laptop gamers and creators alike were very disappointed (especially with the weak 12GB source VRAM loadout).
Leaker Moore’s Law Is Dead (MLID) provides this rumor and substantiates it with photos of (allegedly) engineering samples of the GB203 chip in question. The chip has been reduced to 8,192 CUDA cores (the full capacity is rumored to be 10,752 cores). .
Sources believe this is likely combined with 16 GB of GDDR7 video memory, and MLID points out that this is one of his most powerful Nvidia sources, making it almost certainly a laptop They claim it will be an RTX 5080, or perhaps a 5080 Ti.
VideoCardz, which flagged the issue, further points out that the sample chip’s code name matches a previous leak from laptop giant Clevo.

Analysis: We could see a very peppy RTX 5080 – or will Nvidia still nerf it?
Obviously we need to be careful here, but as MLID themselves admit, there is no conclusive evidence that this is happening as described. For example, this leak may actually be about Blackwell workstation graphics cards. However, the leaker doesn’t think so and is pretty sure this will be the configuration of the laptop RTX 5080, or some of its mobile GPUs.
As MLID further points out, if the RTX 5090 is beefed up with VRAM (again, theoretically up to 24GB of GDDR7), its siblings (and the rest of the Blackwell mobile series) will migrate in concert. Of course you need it. that.
Don’t underestimate the generational performance leap this RTX 5080 can provide. The RTX 5080 mobile continues to use the GB203 chip (albeit a 4x reduction in core count) and combines it with 16 GB of GDDR7 (running at 28 Gbps) for around 50% more performance. I will. Compare with RTX 4080 for laptops.
In a way, this mirrors the spec disappointment of the RTX 4080 (12GB as mentioned), but it’s still a nice step up for the best gaming laptops in terms of non-flagship GPUs. We hope it’s a great top-end value proposition. MLID even believes that generation-to-generation performance improvements could be over 50%, but this is still speculation based on rumors and should be taken with special caution.
It’s also possible that things won’t work, and the leaker suggests that Nvidia could reduce VRAM speeds (below 28Gbps, which is the base flavor of GDDR7) or artificially weaken the graphics card (perhaps in a way that’s required for power supply). It points out that there is. efficiency and heat, at the cost of some performance). It’s not a very attractive proposition as Team Green is likely to tweak this RTX 5080, but this leak makes it seem that way. Of course, this is where the thought comes to mind: “This could be an RTX 5080 Ti.” Unless many next-gen laptop GPUs are very close to availability, it doesn’t make sense for the 5080 Ti to enter testing this early.
In any case, the hint is that Nvidia’s Blackwell GPUs for laptops could very well be a real step up, and these RTX 5000 products could be announced at CES 2025. Or maybe that’s one rumor, which is supported by the fact that sample chips are available. Apparently it’s floating now.
