Starting next week, AMD is going to organize Tech Days in several destinations around the globe, such as London or Paris - during which the company is going to present 28nm Radeon HD 7000 series.
There is a lot of rumors flying around the web, some of which are spun by AMD themselves to raise confusion, as the Radeon HD 7000 series is going to mix the existing VLIW4 and VLIW5 architectures with the “Graphics Core Next” (GCN), introduced during June’s Fusion Development Summit held in Bellevue, WA.
Radeon HD 7000 Series with the old VLIW4 and VLIW5 Architectures
A couple of years ago, AMD and favorable media were all over NVIDIA for mixing different GPU architectures within the same product line. Then with the Radeon HD 6000 series, all of a sudden nobody questioned why AMD mixed two distinctive GPU architectures within a single series (new VLIW4 architecture only powered three high end parts). With Radeon HD 7000 Series, the situation is set to become even more complicated, with AMD mixing no less than three distinctive GPU architectures within the single generation of products.
Given the recent cancellation of 28nm Krishna and Wichita APUs, AMD will rebrand the Brazos 2.0 APU platform as Radeon HD 7200 and 7300 series, and for instance rebranded AMD E-Series APU will be powered by Radeon HD 7200 or 7300 series (all based on Evergreen GPU - VLIW5).
The higher end Trinity APU, the heir to the successful Llano A-Series APU will be powered by a Devastator GPU core, based on contemporary “Northern Islands” VLIW4 architecture, featuring product names such as Radeon HD 7450(D), 7550(D) and so on and so forth.
When it comes to discrete parts, parts with the codename Cape Verde (HD 7500, 7600, and 7700) and Pitcairn (HD 7800), they are all based on the VLIW4 architecture. The “Graphics Core Next” architecture is reserved just for the 7900 Series. Desktop parts are codenamed on Southern Islands, while mobile parts are codenamed after parts of London (read: Cape Verde becomes Lombok, Pitcairn becomes Thames etc.).
If you compare the VLIW4-based HD 6900 and the upcoming HD 7800 series, there isn’t much difference between the two. According to our sources, HD 7800 “Pitcairn” is a 28nm die shrink of the popular HD 6900 “Cayman” GPU with minor performance adjustments. This will bring quite a compute power into the price sensitive $199-$249 bracket and we expect a lot of headaches for NVIDIA in that respect.

So, AMD is taking the lead again. I hope they’ve included DX11.1 support. And i wonder how ridiculous the prices are gonna be…
