Late last week ASUS posted a cryptic announcement, as well as giveaway product questions, on its Twitter page about an upcoming product launch event (scheduled for today - May 10). Hopeful commenters were guessing that a TUF-edition RTX 4070 was incoming, or that a very premature (and potentially surprising) RTX 4060 Ti reveal was due. ASUS has in fact shown off a few new GeForce RTX 4090 custom designs, including a pair of "OG" TUF offerings: "TUF Gaming graphics cards have always been known for their rugged styling, rock solid stability, and excellent gaming performance. The TUF Gaming GeForce RTX 4090 OG and TUF Gaming GeForce RTX 4090 OG OC Edition feature three Axial-tech fans, with the center fan rotating in the opposite direction for less turbulence and fan noise. Dual ball bearing fans, military-grade capacitors, and other TUF components assembled via our Auto-Extreme manufacturing process guarantee reliability for years to come."

The two TUF OG cards look identical from the outside, but the OC edition adds some customized clock speed tunings: 2595 MHz (OC mode) / 2565 MHz (Default mode). The brand new OG models are slightly smaller than their older TUF siblings - 325.9 x 140.2 x 62.8 mm compared to 348.2 x 150 x 72.6 mm (respectively). ASUS thinks that this shrinkage in overall card dimensions will accommodate customers with tighter PC enclosure conditions: "What makes the TUF Gaming GeForce RTX 4090 OG truly stand out is its size. Its sleek 3.2 slot design allows for much better case compatibility than other RTX 4090 graphics cards. If you've been looking for a flagship GPU but couldn't find one that fits in your current build, the TUF Gaming GeForce RTX 4090 OG might be for you."
