Sapphire reveals toxic AMD Radeon RX 6900 XT air-cooled

Sapphire’s Toxic card series is by no means shy, and proudly celebrates their power through colorful paintings and extreme performance. The latest card from Toxic’s lineup, Toxic AMD Radeon RX 6900 XT Air Cooled, Designed for 4K games, with 2425MHz boost clock and 2235MHz game clock and 16GB GDDR6.Like other AMD RDNA 2 Card, the actual clock speed during the game may be slightly higher than the boost clock. The RX 6900 XT is currently AMD’s fastest consumer component and ranked third in our test. GPU benchmark Hierarchical structure, it is one of them Best graphics card (You still can’t buy them because they are all sold out).

Toxic Radeon RX 6900 XT air-cooled has a BIOS switch with three settings: performance, mute and software switch mode. Performance is the default setting, which provides you with the best performance for 4K games. If you want to adjust settings on the fly, the software switching mode allows you to apply your own configuration in Sapphire’s Tri-X software. As you can guess, silent mode reduces the fan speed and runs the card at normal speed for those who don’t need the original performance.

Otherwise, the toxic Radeon RX 6900 XT air cooling will basically bring you some extra highlights and a large cooler.The default game clock 2235 MHz and 2425 MHz boost clock is a bit higher than other factory overclocking cards, but it still uses 16Gbps GDDR6 memory-different from AMD’s pre-built RX 6900 XT liquid coolingIt also has 80 CUs and light accelerators, 128MB infinite cache and 5120 stream processors.

Sapphire recommends a power supply of at least 850W, and the TDP of the card is slightly lower than 400W. Power is provided to the card through two eight-pin and one six-pin power connectors. The powerful force brings a powerful cooling. The fairly powerful graphics card is a three-slot design with dimensions of 320 x 134.8 x 58.4 mm, so you may need to buy a GPU bracket. It is equipped with three aRGB fans and a V-shaped fin stack inside the radiator to help reduce turbulence and noise.

However, the fan on the Toxic GPU is not a standard aRGB fan. Instead, Sapphire is equipped with a hybrid fan. Hybrid fan adopts traditional axial flow fan, which can reduce noise level as much as possible while providing strong air pressure.Not like Tencent 3090, All memory modules are on the same side of the PCB. This allows Sapphire to use their K6.5 cooling design. According to Sapphire, its cooling effect is nearly 38% better than their previous K5 memory cooling module.

Sapphire did not list the release date or price of the Toxic RX 6900 XT Air Cooled, but the Toxic series usually targets the most extreme products. Its cost should be lower than the liquid-cooled variants, but these variants cost more than $2,000, so there is nothing to say.
