ZOTAC debuted a massive flagship GeForce RTX 4090 24 GB custom design graphics card last summer—the Prime Gamer Force (PGF) OC edition model was released as a China exclusive product. ZOTAC's PGF shroud design remains the largest on the market—381 mm (L) x 154 mm (W) x 74 mm (D)—even with downgraded silicon beneath the surface. NVIDIA's China-specific GeForce RTX 4090D GPU was introduced last December, as a sanction conformant substitute for the full-fat version—naturally, ZOTAC has prepared a revised PGF model. This week, Expreview has published an in-depth review of the GeForce RTX 4090 D PGF OC edition graphics card. They found that ZOTAC's cooling system—three 11 cm fans and a vapor chamber—offered: "high-frequency stability...comparable to that of water-cooled (solutions)."

The Chinese publication reviewed the GALAX RTX 4090 D Metal Master model in January—at the time, software restrictions prevented the implementation of significant overclocks. It was theorized that future updates or community workarounds could bypass limitations, but the latest review—of ZOTAC's "super luxurious" PGF edition—indicates that this GeForce RTX 4090 D GPU's OC potential is still constricted. VideoCardz has pulled out essential details from the Expreview article: "(The PGF) has high maximum TGP (530 W) and a powerful 28-phase power PCB design. Despite the technological headroom, the card struggles to offer much of the overclocking potential. The team from Expreview only managed to squeeze 3.7% more performance from this card. That's despite 24.7% more power theoretically available." An underwhelming overclocking aspect is counterbalanced by the premium-tier card's impressive performance stability—the review also praised ZOTAC's quiet cooling solution and usage of high-end "heat dissipation materials."

The first review of a Chinese-exclusive "RTX 4090D" GPU model hit the internet last week—Expreview received a sample GALAX RTX 4090 D Metal Master model not long ago, and their testing team proceeded to find out whether the nerfed version of NVIDIA's flagship gaming GPU was truly compromised in terms of performance. Effective October 2023, the US Federal Trade Commission placed restrictions on Team Green—thus blocking trade of units based on the "Ada Lovelace" AD102-300 GPU in China. In turn, a variant—AD102-250-A1—was prepared in order to confirm to new policies.

NVIDIA's China-specific GeForce RTX 4090D launched officially right at the end of 2023. Board partner GALAX seems to be leading the pack, with customized versions being sent out for evaluation. The GeForce RTX 4090D GPU arrives with a lesser configuration: 14,592 CUDA, 456 Tensor, and 114 RT cores—but the first review indicates that this only trails behind its uncompromised sibling by roughly 5 to 6% across sixteen games. It lags behind in Stable Diffusion benchmarks—an AI workload at 512x512 resolution shows a 10% difference, although the gaps narrows at 768x768 and 1024x1024.
