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."Expreview noted a size-related negative point: "In terms of shortcomings, the size of this graphics card is slightly larger. Friends who want to buy it need to match the chassis data in advance. However, the appearance design of this Zotac GeForce RTX 4090 D PGF graphics card is also relatively excellent, so it looks good after using it. On the contrary, it makes the inside of the chassis look more substantial. Currently, this Zotac GeForce RTX 4090 D PGF graphics card has been put on the e-commerce platform, priced at 16,999 yuan (~$2362)."The Expreview evaluation includes detailed unboxing and teardown processes.
