Specs for Nvidia’s yet-to-be-released RTX Titan Ada GPU have allegedly surfaced on Reddit. GPU-Z screenshot and photo provided by FluxRBLX on the Nvidia subreddit reveals rumored but never delivered specs for the RTX Titan Ada GPU, including a fully-supported AD102 GPU and an impressive 48GB of VRAM.
The GPU-Z screenshot reveals many details about the alleged Titan Ada GPU prototype, including core count, memory configuration, device ID, and more. The GPU would have 18,432 shaders (CUDA cores), 192 ROPs, 576 TMUs, a pixel fill rate of 478.1 GPixel/s and a texture fill rate of 1434.2 GTexel/s. The memory subsystem is 48 GB in capacity (48 GiB if we’re being precise), featuring GDDR6 (non-x) chips on a 384-bit memory interface with a bandwidth of 864 GB/s.
Base clock speeds are significantly lower than any of the outgoing RTX 40-series (Ada Lovelace) GPUs, with GPU-Z reporting clock speeds of just 735MHz. However, the boost clocks look much more conventional and are 2490 MHz. The abnormally low base clocks are likely a byproduct of the early nature of the hardware, as this card was supposedly a prototype. This may also explain the operate of GDDR6 instead of GDDR6X.
Compared to the RTX 4090, the RTX Titan Ada outclasses it in terms of the number of shaders and memory capacity. The Titan Ada has a fully activated AD102 die, which would make it the only RTX graphics card in the 40 series family to have a fully unlocked die. The RTX 4090 has access to 89% of the AD102 chips.
The memory capacity of the Titan Ada graphics chip is also doubled, which inevitably results from the operate of a “clamshell” configuration with GDDR6 modules on both sides of the PCB, similar to the RTX 3090 or RTX 6000 Ada. GDDR6 manufacturers do not produce GDDR6 memory chips with capacities larger than 2 GB, making this configuration the only option for getting 48 GB on a Titan-class graphics card.
One area where the RTX 4090 outperforms the Titan Ada is memory bandwidth, thanks entirely to GDDR6X memory. The Titan Ada prototype had slower GDDR6 memory modules, which reduced its bandwidth potential compared to the RTX 4090. Nvidia either didn’t plan to operate faster GDDR6X modules, or perhaps never got that far. Cooling could be an issue due to the clamshell layout of the memory chips; The RTX 3090 shipped in the same configuration as the GDDR6X modules, but the RTX 3090 also suffered from memory temperature issues.
The Reddit poster also shared a photo of the PCB of the alleged RTX Titan Ada GPU. Assuming the image is real, the PCB looks virtually identical to the equivalent RTX 4090 PCBs. The giant AD102 die sits in the center, flanked by 12 of the 24 memory chips. The GPU and memory power supply components are located on the right and left sides of the PCB. The PCB pictured here is likely a reference design, as Nvidia usually doesn’t allow non-reference Titan cards (even if they’re not branded “Founders Edition”).
Since this GPU was never released, Nvidia did not explain why it never launched the RTX Titan Ada. However, Nvidia likely discontinued the product due to the internal competition that would arise between it and workstation-class GPUs such as the RTX 6000 Ada sold for $6,800. Moreover, AMD had no answer for the RTX 4090, so the RTX Titan Ada may have turned out to be overkill, at least for the average gamer.
