A special edition of the Colorful GeForce RTX 4090 has been spotted online, the Colorful RTX 4090 iGame LAB. This will be a special limited edition graphics card designed specifically for overclocking. Spotted over on Bilibili.com, the Colorful RTX 4090 iGame LAB will be only made in 300 units and looks similar to the Colorful iGame Vulcan version, just in white color. The card is a result of Colorful's in-house overclocking team and will apparently have binned GPUs, which means it could reach higher clocks.

Since there is no Colorful RTX 4090 iGame KUDAN version, the iGame LAB will take the flagship place. According to the specifications the RTX 4090 iGame LAB will still feature a single 16-pin power connector which means it will still be limited to 600 W. The specifications also mention the 2625 MHz Boost GPU clock. Unfortunately, there is no word on global availability or will it be limited to China only.

ASUS ROG has started selling its RTX 4090 XG Mobile external graphics card in China and Japan this week. Japanese customers are being charged a cool $3000 for the pint-sized powerhouse external GPU, and Chinese buyers are getting a slightly better deal at $2700. It should be noted that this eGPU is the (GN21-X11) mobile variant of the GeForce RTX 4090, and not the full fat desktop version. The newly updated XG Mobile enclosure can only be connected to an ASUS Flow laptop, which limits the scope of compatibility to an already very expensive range of devices. The proprietary connection standard will keep customers in the ASUS ROG mobile hardware ecosystem - but their higher end laptop models can be configured with the very capable GeForce RTX 4070 mobile GPU, so the RTX 4090 XG Mobile seems to appeal to a very small buying niche.

The XG Mobile interface uses the PCIE Gen 3 x8 standard of connection, and the GPU has access to a dedicated 63 GB/s of bandwidth. This beats the Thunderbolt 4 standard of 40 Gb/s, by a 57% margin. The enclosure acts as a docking station - its features include an up to 2.5 Gbit Ethernet, a single HDMI 2.1 port, one DisplayPort 1.4 with G-Sync support and three USB 3.2 Gen 2 ports (3x Type-A + 1x Type-C). ASUS ROG has engineered the docking station/enclosure to be as compact as possible (21.7 cm x 16.5 cm x 3.26 cm), when compared to competing products from other manufacturers. The whole package weighs in at 1.3 kg, which will ensure decent portability for gamers on the move.
