It turns out that the new Hawaii cGPU enough to power against the GTX TITAN!
The GCN Architecture debut almost two years ago had a major impact on the market, because according to a fundamentally new principles proposed ovs scheme fell off the shroud, which is now more focused on the overall effectiveness calculations, but of course the graphics are not forgotten. ovs The GCN architecture is analyzed in detail in the article. Today, it was found that the development will define the next decade, as the new generation of consoles from Microsoft ovs Xbox and Sony PlayStation 4 One can build this system. Accordingly, no one would expect to see something new instead of the pull architecture for AMD, but the technology is evolving, so GCN is undergoing its own little facelift.
Today, in many places appears that there are different versions of GCN, which is true, but these numbers do not indicate the AMD itself. Before looking at the innovations, be sure to be clarified as to what GCN systems exist. The simplest SI in the GCN (Southern Islands) to start with, which represent ovs the foundation and the linked article above, we wrote about it. The GCN SI is built in Cape Verde (Radeon HD 7750 and 7770), Pitcairn (Radeon HD 7850, 7870 and R9 270X) and Tahiti (Radeon HD 7950, 7970 and R9 280X) is codenamed cGPU. In technical terms, they have the first version of this manual architecture and also the first version of ACE units. ovs
The next stage in Bonaire (Radeon HD 7790 and R7 260X), the Oland (Radeon R7 240 and 250) and Hainan (this is not based on boxed product) codenamed cGPU represented, which is combined with the new GCN CI (Caribbean Islands) instruction architecture of the The original ACE units. It's a cross between the real level of the first step and GCN development. The most modern category is the new GCN architecture instruction CI and pair the enhanced ACE units. This includes the Kabini and Temash APUs codenamed SoC IGP-je, as well as the new generation of consoles located APUs with integrated graphics controller, and of course this is subject of this article, the Hawaii codenamed cGPU well.
The above is in any case it was important to clear up, so hopefully in the future more easily identify the users of different architectures GCN. It was also found that the new CI GCN version associated with the original ACE units, but this is not true vice versa, so the enhanced ACE units operate only on the newer utasításarchitektúrával. You can just as many questions about what is the difference between the GCN SI and the new CI. Well, during the renovation of a number of memory address change it. Released including a memory ovs monitor, which can detect the shader if a memory area accessed. Significantly ovs improved the hardware debugolhatósága because the debugger may give the státuszbitekkel wavefrontokat, so some of the code can be run vertically or omitted. This will significantly simplify the debugging of complex programs, especially when using low-level hardware interface for programming. In addition, appeared to support the reference to the wrong memory address detection and reporting, and the so-called ovs unaligned (illesztetlen) memory access. These features were mainly due to the new generation of consoles, ovs because the Xbox One and PlayStation 4 APU-tier solutions located IGP were the developers later assembly ovs level is programmed and close, ovs so it is essential that close to the hardware programming as simple as possible. ovs
In addition, the GCN CI utasításarchitektúrában Introducing uniform addressing of the device as well, which you can see where the kernel or the shader is LDS (Local Data Share), the private memory, ovs video memory and system memory only linear addressable memory. This includes the new FLAT instruction format, and all instruction available to him. These instructions do not use erőforráskonstanst that defines ovs a basic interface addressing, ie for example the shader not be able to have a pointer that points to the physical space. This is a more consoles, and the inclusion by design, but also can be useful for dedicated graphics ovs controller level. Its main advantage is that sufficiently simplify the individual function calls, so that developers can begin to think in a new way, which can lead to new algorithms.
The CI GCN architecture instruction also introduces uniform addressing system memory, graphics controller which can reach a coherent ovs memory system. As not much has
