Just asking a question here, almost bought one of these over the weekend but decided to recycle an old X6 for my wife. When I in inquired about Richland on the forums I was told that Richland would be - maybe - 10% faster than a similarly clocked Trinity - is that accurate?
Absolutely not. There is 0 IPC gain for trinity (its the exact same physical chip except with power/bios/turbo tweaks). Richland performance gains come 100% from increase speed and for mobile increased speed and better thermals allowing higher clocks and turbo (mobile richland, especially ULV is expected to see much better gains than desktop high level richland).
For the 10-5800k vs a10-6800k we are looking at a ~10% increase in cpu power (4.4 ghz for richland vs 4.0 ghz for trinity) and a ~5% gain in gpu performance (844 mhz for richland vs 800 mhz for trinity). Its really nothing special considering you can easily overclock any a10-5800k to those levels. However, richland may bring about some power savings (doubtful on the desktop as 4.4 ghz is quite far along the non-linear power/clockspeed curve)
Richland is literally part of AMD's marketing genius. Take your old chip, tweak it a little for higher clocks and market it as something else entirely and everyone thinks you get huge performance gains when you won't.
(The same thing for intel would be to release an i5 chip say the i5-3590k with a base clock of 3.6 ghz turbo 4.0 ghz and igp at 1300 mhz and market it as a major step forward [which it isn't]. Kinda pointless considering any i5 k version overclocks to these levels easily.)
