This means that there no longer is a fixed clock on these cards. And much like NVIDIA does, AMD now fully implemented a 'Turbo' feature much like NVIDIA's boost technology on all of their products. And who can remember Oland, that mobile GPU ? Well peek at the R7 250 specs, looks familiar right ? There are a number of changes though to be found in clock and memory frequencies so overall there will be slight performance increment's. The R7 260X is a new GPU, but the R9 270X and R9-280X both are derivatives of the Pitcairn and Tahiti GPUs respectively. Yes, much like NVIDIA has done with the 700 series AMD is doing something very similar. R9 280X (previously the R7970 Ghz / Tahiti) R9 270X (previously the R7870 Ghz / Pitcairn) API - DirectX 11.2 / OpenGl 4.3 / Mantle.The entire segment from top to bottom has been released in Q1 2012, but most of the 2013 models are respins, the exception being the R7-260X and the R9-290/290X graphics cards. Enthusiast level Hawaii = R9-290 and 290X.

High-end level = Tahiti = Radeon HD 7900 series / R9 series.Mainstream level = Pitcairn = Radeon HD 7800 series / R7 series.

Entry level = Cape Verde = Radeon HD 7700 series / R5 series.

Pitcairn would be the codename the mainstream products (7800) will hide under, and Tahiti is the codename for the GPUs used on AMD's most high-end graphics cards. When you notice 'Cape Verde' that's entry level, the 7700 series that was just released. It's simple really, in the market we have entry level, mainstream and high-end products. Over the past two years you have been hearing about several codenames and that can be a little confusing. So let's deal with a quick overview of the AMD new product range first.
