NVIDIA’s Ada Lovelace architecture was unveiled last month during the GTC Keynote. Jensen Huang showcased NVIDIA’s RTX 4090 & the RTX 4080 16/12GB GPUs. However, the RTX 4080 12GB could not see the light of day. Similarly, along with all these GPUs, there was a Titan ‘in the works’ leaked to be equipped with a whopping 48GB of memory. This GPU is, or was supposed to be powered by the full-fat AD102 chip. Although, recent rumours suggest that this GPU may see a similar fate to the RTX 4080 12GB.
Ada Lovelace Titan
Leaks and rumours started to pop up as early as July by Kopite. Being very initial leaks, they did have a few questionable figures. The ‘AD-450-A1‘ (Full-Fat AD102) fueled Titan should house 144SMs, although the leaked variant featured only 142.
48G 24Gbps GDDR6X
total board power ~800W

This resulted in a big discrepancy because the ‘leaked‘ RTX 4090 Ti features a similar SM count. So, we assumed that the Ada Lovelace Titan will ship with 18432 Shading Units (144SMs) if it ever hit the shelves.
The Initial Signs
However, MLID (Moore’s Law Is Dead) pointed out that we may not see such a behemoth citing power conerns. Allegedly, the RTX 4000 Titan was tripping breakers, melting PSUs and sometimes even melting. Do note that we do not have concrete proofs to back such claims. In addition, the GPU was a massive 4-slots thick and required 2×16 pin power connectors.
MLID did receive some criticism because of these statements. Some pointed out that a GPU cannot possibly ‘melt’ power supplies and ‘trip’ breakers. MLID’s main point might have been authentic as highlighted by today’s leak, however, the stated argument was debatable.
‘There really was a 600W-700W card in the labs that has been cancelled due to the tripping breakers and melting power-supplies’ I’m not sure if I’d rather laugh on this bullsh*t statement or cry on this. There weren’t any cards lately consumes that amount of power, but you could apply the custom-bios like I’ve done with my RTX 3080 once and ran on 450W and no, even the cards goes 600W it wouldn’t trip the breakers and ‘Melting’ power-supply? Who is this clown, I mean, who the F wrote this statement? The Power-supply trips, even the cheaper power-supply would shut-it down safely (By cheap, I mean quality PSU’s still as Pylon not Thunder, Red Dragon) if there is excessive power going through the 12V Rails to power-the GPU than the PSU could handle. More power is not bad, Nvidia engineers are following specifications provided by Intel ATX 3.0 or PCI-SIG standards and power-supplies manufacturers are not dumb they know what they are doing in the labs unlike this clown who made this statement.

Just recently, Kopite on Twitter shared a sort-of official confirmation that we probably won’t see a Titan from Ada Lovelace. Maybe NVIDIA is delaying their kingpin until AMD unveils the long-awaited RDNA3 lineup. Only time will tell.
We won't see Titan of Ada Lovelace. 😩

All in all, this does beg the question. Which SKU will be powered by the full-fat AD102 chip? We have 2 possibilities;
- NVIDIA could pack the full AD102 GPU in their Quadro Lovelace lineup
- NVIDIA could launch the RTX 4090 Ti with the complete AD102 GPU
Either way, the earliest we could expect some information from NVIDIA is during the CES 2023. Team green is expected to release the remaining RTX 4000 GPUs namely;
