MSI's Radeon R9 285 GAMING OC does not yet show up for sale but with it's factory overclock may arrive at a slightly higher price than the MSRP of $250. The RAM remains at the default 5.5 GHz but the GPU has been bumped up 55MHz to 973MHz out of the box and could likely be pushed higher as MSI has included the usual suspects on this card, Twin Frozr IV Advanced and Military Class 4 components. In [H]ard|OCP's testing the card was well matched by the GTX 760, the HD 285 won more than it lost, but not always and not by much. Compared to the HD 280 not only did the new Tonga card usually provide better performance but the additional feature the GPU supports, of which FreeSync is only one, make the HD 285 the clear winner in that contest. Check their full review for benchmarks.
"AMD has launched the $249 AMD Radeon R9 285 video card. We dive into this somewhat confusing GPU. We compare it to the GeForce GTX 760 as well as an AMD Radeon R9 280. We'll discuss GCN differences in this new video card that may give it the edge with some feedback from AMD."

Tonga GPU Features
On December 22, 2011, AMD launched the first 28nm GPU based on an architecture called GCN on the code name Tahiti silicon. That was the release of the Radeon HD 7970 and it was the beginning of an incredibly long adventure for PC enthusiasts and gamers. We eventually saw the HD 7970 GHz Edition and the R9 280/280X releases, all based on essentially identical silicon, keeping a spot in the market for nearly 3 years. Today AMD is launching the Tonga GPU and Radeon R9 285, a new piece of silicon that shares many traits of Tahiti but adds support for some additional features.
Replacing the Radeon R9 280 in the current product stack, the R9 285 will step in at $249, essentially the same price. Buyers will be treated to an updated feature set though including options that were only previously available on the R9 290 and R9 290X (and R7 260X). These include TrueAudio, FreeSync, XDMA CrossFire and PowerTune.
Many people have been calling this architecture GCN 1.1 though AMD internally doesn't have a moniker for it. The move from Tahiti, to Hawaii and now to Tonga, reveals a new design philosophy from AMD, one of smaller and more gradual steps forward as opposed to sudden, massive improvements in specifications. Whether this change was self-imposed or a result of the slowing of process technology advancement is really a matter of opinion.

A little secret popped out with the release of AMD's FirePro W7100, a new family of GPU that goes by the name of Tonga, which is very likely to replace the aging Tahiti chip that has been used since the HD 7900 series. The stats that The Tech Report saw show interesting changes from Tahiti including a reduction of the memory interface to 256-bit which is in line with NVIDIA's current offerings. The number of stream processors might be reduced to 1792 from 2048 but that is based on the W7100 and it the GPUs may be released with the full 32 GCN compute units. Many other features have seen increases, the number of Asynchronous Compute Engines goes from 2 to 8, the number of rasterized triangles per clock doubles to 4 and it adds support for the new TrueAudio DSP and CrossFire XDMA.
"The bottom line is that Tonga joins the Hawaii (Radeon R9 290X) and Bonaire (R7 260X) chips as the only members of AMD' s GCN 1.1 series of graphics processors. Tonga looks to be a mid-sized GPU and is expected to supplant the venerable Tahiti chip used in everything from the original Radeon HD 7970 to the current Radeon R9 280."
