AMD Tonga Based Radeon R9 285 Graphics Card Scheduled For Q3 '14 - Features 2 GB, 256-Bit Memory, Replaces Tahiti

AMD is preparing their next generation Tonga GPU for launch and Sweclockers has but revealed a bunch of data regarding the naming scheme of the carte du jour itself. The new Tonga GPU based card volition be known as Radeon R9 285 and will supplant the aged Tahiti core which has nigh spanned a good three years lifetime.

AMD Tonga Based Radeon R9 285 Graphics Card Scheduled For Q3 '14

Nosotros accept known Tonga for a while as information technology was i of the names which appeared in Catalyst files dating back to AMD's GPU 'xiv printing result. The GPU which was actually supposed to be a role of AMD's electric current Volcanic Islands R9 200 series line was pushed back in AMD's GPU roadmap since AMD preferred rebranding almost half of their products for the new lineup. AMD went ahead to rebrand the Pitcairn, Cape Verde and Tahiti chips into the R9 200 serial cards we know today that come at amazing value but characteristic the exact same specifications from ii years ago. Well, the time for their retirement is coming close as AMD is one the verge of launching their successors.

While Tahiti is generally replaced by its successor Hawaii, it is still a role of the electric current R9 200 series line as a operation part rather than the high-end product. AMD's Tonga GPU which volition feature the Radeon R9 285 branding will replace the Tahiti core only Tahiti will stop to exist until the launch of AMD's adjacent generation graphics lineup "R9 300" series since two cards, the Radeon R9 280X and Radeon R9 280 are based on Tahiti XT and Tahiti Pro GPUs and AMD has no plans to launch a product in this price market.

The Radeon R9 285 will be price in the $300 United states of america range which means that Tahiti based cards will be receiving a major price cut equally hinted previously to brand room for the new cards otherwise having both Tahiti XT and Tonga at the same cost volition mean poor sales for the inferior product of the two. The card will launch in Q3 2022 and the verbal engagement is pitted somewhere between belatedly Baronial and Early September merely information technology is definitely coming out soon and we volition commencement receiving more information in the coming weeks.

The specifications for the carte include a ii GB GDDR5 buffer running across a 256-bit bus interface. This is actually lower than Tahiti'due south iii GB GDDR5 VRAM and 384-bit omnibus just Tonga is rumored to include faster 7 GHz memory modules which will outcome in higher bandiwdth and carte du jour makers will have the option to launch iv GB models later on in product. The menu volition be built on a new compages which is presumably the GCN 2.0 design and non the GCN ane.1 compages which has been featured on Bonaire and Hawaii. The Tonga graphics architecture will exist built on the 28nm node from TSMC (if rumors are to exist believed) and would feature a new blueprint scheme introducing latest architectural improvements such every bit new ACE (Asynchronous Compute Engine) Units and more focus towards compute shaders. It is also mentioned that Tonga will retain the bones technologies of the Radeon lineup such as Mantle, TrueAudio and XDMA for CrossFire support. Performance efficiency would exist a main focus of the new menu and the ratings could be expected somewhat like to Maxwell if not the same.

It should as well exist noted that the Radeon R9 285 leaves room for another variant codenamed as the Radeon R9 285X. The Radeon R9 285 could exist featuring the Tonga Pro GPU just like Tahiti Pro while the fully enabled Tonga XT die volition be featured in the Radeon R9 285X variant. The actual launch of the other variant is not known nor do nosotros know whether such a model exists or not just given AMD's past GPU scheme, we believe that AMD will have two variants of Tonga.
