Radeon R9 390 Toxic Features The Highest Factory-overclock by Sapphire
While AMD Polaris–the next-gen GPU architecture–is just around the corner, OEMs can’t stop releasing new products based on the current gen AMD GPUs. As of the latest, Sapphire has unveiled its highest tuning air-cooled TOXIC variant for the Radeon R9 390.
Aimed at the Asia-Pacific region, the card features a swanky new VaporX vapor-chamber cooling solution, with a black PCB design. The R9 390 Toxic is clocked at 1120 MHz against reference clocks of 1000 MHz, and an untouched 6.00 GHz (GDDR5-effective) memory clock, making it the highest factory-overclocked version by Sapphire.
R9 390 Toxic features an impressive cooling solution that includes a large vapor-chamber plate to convey heat to two aluminium fin stacks via 8 mm-thick copper heat pipes. To enhance the effect, nearly every other part of the PCB is covered by a ridged aluminium base-plate, keping the VRM and memory chips super cool.
Spec-wise, the R9 390 is built using the 28nm “Grenada” silicon, and features 2,560 stream processors, 160 TMUs, 64 ROPs, and a 512-bit wide GDDR5 memory interface, holding 8 GB of memory.
Pricing and availability details of Sapphire R9 390 Toxic are not revealed yet.
