Nvidia’s Geforce RTX 3090 Ti graphics card based on the GA102-350 GPU has recently gone on sale and has already proven itself on the test bench with a recommended price of 2249 euros and a board power of 450 watts. in the PCGH test. Manufacturers are now gradually introducing their own models of the new enthusiast graphics card, including Gigabyte with the liquid-cooled Aorus Geforce RTX 3090 Ti Xtreme Waterforce 24G and the pure air-cooled Geforce RTX 3090 Ti Gaming OC 24G.

The former measures 23.8 x 14.1 x 4 centimeters and relies on a connected 360mm aluminum heatsink with three 120mm double ball bearing fans that should keep the graphics card stable and cool even at high overclocks. The copper plate, when replaced, relies directly on the GPU, VRAM and “other important parts.” as advertised through a strong FEP tube 460 mm long. Boost clock speed is increased in terms of overclocking to 1935 MHz compared to 1860 MHz on the reference model, while 24 GB GDDR6X memory remains untouched with an effective data transfer rate of 21 gigatransfer/s compared to the reference.

According to the announcement, in addition to the backplate and part-matte, part-mirror design, both announced models also use “a multi-phase power supply design to allow the MOSFETs to operate at lower temperatures.” Added to this are thermal protection and load balancing for each MOSFET, combined with certified “heavy duty” coils. On the connection side, there is one new 16-pin power connector (adapters from 12-pin to three 8-pin included), three DisplayPort 1.4a and one HDMI 2.1. Recommended power 850W.

Less OC on air-cooled model

The 33.1cm x 15cm x 7cm pure air-cooled model relies on the acclaimed Windforce 3X cooler with what the manufacturer says are specially finned fans and double ball bearings, as well as a counter-rotating fan in the middle for better heat distribution. In addition, there is a vapor chamber in contact with the GPU, VRAM and MOSFET, including eight copper composite heat pipes and Gigabyte’s “Screen Cooling” technology as a radiator extension, which should not impede airflow and should avoid a constant increase in temperature. heat.

In addition, the board has a dual BIOS switch to select between OC and Silent modes. At 1905 MHz, the clock speed is lower than the AiO model, while the GDDR6X memory remains intact here. Meanwhile, there is also a non-OC model on the official website listed.

While Gigabyte RTX 3090 Ti custom models come with a four-year warranty if you register online within 30 days of purchase date, there is still no pricing or availability information for the announced models. There is also no listing in the PCGH price comparison: there are currently only two custom models from MSI and Zotac. from 2429 euros.
