Specifications of Nvidia's unreleased RTX Titan Ada GPU have allegedly surfaced on Reddit. A GPU-Z screenshot and photograph shared by FluxRBLX on the Nvidia subreddit reveals the rumored but never shipped RTX Titan Ada GPU specifications featuring a fully enabled AD102 GPU and a whopping 48GB of VRAM.
The GPU-Z screenshot reveals many details on the purported Titan Ada GPU prototype, including core counts, memory configuration, device ID, and more. The GPU would have had 18,432 shaders (CUDA cores), 192 ROPs, 576 TMUs, a pixel fillrate of 478.1 GPixel/s, and a Texture Fillrate of 1,434.2 GTexel/s. The memory subsystem has 48GB of capacity (48GiB if we're being precise), featuring GDDR6 (non-x) ICs on a 384-bit wide memory interface with 864 GB/s of memory bandwidth.
Base clock speeds are significantly lower than any outgoing RTX 40 series (Ada Lovelace) GPU, with GPU-Z reporting a clock speed of just 735 MHz. However, boost clocks look far more conventional, rated at 2,490 MHz. The abnormally low base clocks are likely a byproduct of the early nature of the hardware, as this card was purportedly a prototype. That could also explain the use of GDDR6 instead of GDDR6X.
Compared to the RTX 4090, the RTX Titan Ada outclasses it in shader count and memory capacity. The Titan Ada features a fully enabled AD102 die, which would have made it the only RTX-branded GPU in the 40-series family to have a fully unlocked die. The RTX 4090 has access to 89% of the AD102 die.
Memory capacity is also doubled on the Titan Ada GPU, inevitably due to using a "clamshell" configuration with the GDDR6 modules on both sides of the PCB, similar to the RTX 3090 or RTX 6000 Ada. GDDR6 manufacturers don't make GDDR6 memory chips with a capacity greater than 2GB, making this configuration the only option to achieve 48GB on the Titan-class GPU.
