NVIDIA RTX 4080 rumored specs updated with faster memory
Another week, different update to RTX 40 specs.
NVIDIA is moving astir the timepiece to hole their next-gen GPU bid for motorboat aboriginal this year. This besides means that the institution is cycling done aggregate cards specs portion they measure their outgo and show of each model. Kopite7kimi, amended known for his close RTX 30 “Ampere” leaks, is providing predominant updates connected however the RTX 40 bid specs change, and yes, they alteration a lot.
According to the latest update, NVIDIA GeForce RTX 4080 SKU mightiness get faster 23 Gbps GDDR6X memory. This is an upgrade implicit erstwhile specs listing 21 Gbps, and perchance an indicator that the flagship RTX 4090 volition get akin velocity arsenic well. Furthermore, Kopite present claims that the TBP has changed from 420W to 340W. Note this is the full committee power, not TDP.
Let's marque immoderate updates.

The remaining specs did not change, and this exemplary is inactive expected to get AD103 GPU with 9728 CUDA cores and 16GB of representation crossed a 256-bit bus.
Those unfamiliar with NVIDIA accumulation rhythm mightiness deliberation that Kopite is conscionable making those specs up, but remainder assured NVIDIA truly does alteration the prelaunch specs precise often. Some of these cards look connected the leaked roadmaps (RTX 3070 Ti 16GB, RTX 3080 20GB etc.) but are aboriginal canceled oregon postponed (RTX 3090 Ti, GTX 1630).
So yes, it is precise apt that those updates are based connected existent information, immoderate we tin adjacent corroborate ourselves, but Kopite’s updates are overmuch faster. However, 1 shouldn’t automatically presume those specs are final, aft each we are inactive 1.5 – 2 months distant from authoritative launch.
