AMD Radeon R9 285 Tonga Graphics Cards From Various AIBs Pictured

AMD'southward Tonga GPU is codenamed the Radeon R9 285 and features the Tonga GPU. It cannot be said whether this is the total core or a skimmed up core "Tonga Pro" since there's a possibility that the fully enabled cadre could have the Radeon R9 285X codename. Regardless, nosotros are looking at performance on the levels of Radeon R9 280 while keeping the thermal specs and power consumption at R9 270X levels. This suggests that the Tonga GPU is highly efficient and AMD took this arroyo due to NVIDIA's recent Kepler launches which turned out to deliver neat performance at absolute low TDPs of 65W (GeForce GTX 750 series).

For specifications, the card volition feature a 2 GB GDDR5 memory running across a 256-fleck bus interface and the clock speeds are maintained at 918 MHz core and 1375 MHz retentivity which result in a cumulative bandwidth of 176 GB/s. The power is provided through dual vi-Pin connectors and display outputs include Dual-DVI, HDMI and a display port for all iii cards. Nosotros don't have any specifics regarding the core count and the number of raster operation units but we should focus on the details we now have whilst looking at the Radeon R9 285 cards. The bandwidth is major decline over the R9 280X which features a 288.0 GB/s cumulative bandwidth so maybe the card is less dependent on it and there'south some secret sauce inside the GPU which we don't know about notwithstanding.

The cards nosotros are looking at are from Sapphire (Radeon R9 285 Dual-X), XFX (Radeon R9 285 Double Dissipation) and HIS (Radeon R9 285 IceQ X2 Mini). If you might have noticed, and then all these cards feature a heatsink that is featured on the Radeon R9 270 serial cards rather the Radeon R9 280 which features more beefy cooling and heatsink solutions. The reason behind this could be the fact that the card consumes lesser ability and runs much cooler than what we are used to on Tahiti based cards. As mentioned earlier, the card is specifically a Radeon R9 270 in terms of design only boasts R9 280 performance thanks to core performance improvements. The design and GPU compages for Tonga are new and remain a mystery until the cards are fully shown off and then that is one reason nosotros can think for the modify. The card as well isn't much longer than the R9 280 cards and really a tad bit smaller then AMD has learned to managed components on their PCBs. It's non known whether these cards employ the reference PCB, but from the looks of it, they are featuring custom designed PCBs.

There'southward another interesting thing regarding Radeon R9 285 that is the card makes use of AMD's XDMA CrossFire technology. At the side of the PCB, nosotros can run across that AMD hasn't featured Crossfire gold fingers merely instead went with their XDMA road allowing upto ii GPUs to work in harmony sharing an interconnect path via the PCI-e. This technology has already proved well for the Hawaii graphics cards and the reason why no other cards than Hawaii and Tonga feature this is because the rest of AMD'south lineup were rebrands of previous generation chips.

The Radeon R9 285 volition be price in the $300 US range which means that Tahiti based cards volition be receiving a major price cut as hinted previously to make room for the new cards otherwise having both Tahiti XT and Tonga at the same toll will mean poor sales for the inferior product of the two. The card volition launch in Q3 2022 and the verbal date is pitted somewhere around tardily August just it is definitely coming out soon and we will start receiving more information in the coming weeks.
