ZOTAC has released its most premium GeForce RTX 40 variant, the RTX 4090 PGF, for the Chinese market, and it’s an absolute monster.

ZOTAC’s Flagship GeForce RTX 4090 PGF Adopts Vapor Chamber, 28 Phase VRM & A Monsterful Design

The ZOTAC GeForce RTX 4090 PGF features a revamped design with a similar design language to the “AIRO” lineup. It has a minimal white color scheme & concentric RGB lighting running alongside the fans. The RTX 4090 PGF comes with a metal backplate with the PGF diamond logo on the right, which also features an RGB option. It also has ventilation cutouts at the back, allowing the radiator to blow directly through it. The dimensions measure 381mm x 154mm x 74mm, becoming one of the lengthier cards on the market.

ZOTAC’s GeForce RTX 4090 PGF packs everything one could need for cooling. It adopts a vapor chamber cooler that helps spread the heat inside the GPU through metal plates and transfers the heat through seven composite heat pipes.

The card also comes with a triple-fan configuration with three fans, each with a diameter of 11cm, and nine white fan blades. The middle fan rotates in an opposite direction which helps in forming a forward and reverse air duct, contributing to efficient cooling. The fan blades also have a black brushed texture with the “PGF” branding.

The main difference in the ZOTAC GeForce RTX 4090 PGF is its clock speeds & power consumption. It uses a 24+4-phase VRM design, which can fully withstand power consumption above 500W. The core frequency can reach up to 2625MHz, much higher than the reference RTX 4090. ITHome has tested the RTX 4090 PGF through various instances, which you could view to know about the GPU’s performance.


ZOTAC RTX 4090 PGF will not launch globally yet and is limited to Chinese markets. The pricing for the GPU is around 17,599 RMB (USD 2,500) which is what we can expect for such a high-tier variant. You can view real-life images of the RTX 4090 PGF below to admire its beauty. (Credits: ITHome)
