			<description><![CDATA[@deadspeedv, the CNG GPU can be "partitioned" so to speak, parts of the GPU can deal with a game, console port or not, and other parts with computing or folding, you name it, this is why such power requirements are also needed, if this GPU is used at its fullest it could draw the maximum power as we see in tests when furmark is used, of course, older GPU's are task sensitive and such a test is not worth anything to most people, but now it might become one. But not to be the ultimate fanboy, let's just wait and see the actual chip in action before we decide what is wrong with it and what not.]]></description>

			<description><![CDATA[I am aware of that article and even posted it in my previous comments. Look closer. The thing is we don't know why SI apparently needs so much power. That's the question, although I firmly believe it's because of new compute oriented shaders. It's a rumor after all and maybe fudzilla is wrong about 7950. Maybe only 7970 comes with 8+6 pin connectors and 7950 is actually 6+6. Or maybe 7950 is really 8+6, but consumes less than 225W but very close to it, so they decided to use 8+6 to leave room for overclocking.]]></description>

			<description><![CDATA[That's what happens when you have an incompetent marketing department, people doubt what you'll say until proven so or otherwise. But now they are gone... even so it seems a bit hard to believe AMD, although I do, I've seen the GCN presentations some time ago.]]></description>

			<description><![CDATA[Don't know why you guys are guessing what's inside a 7900 GPU. AMD gave a keynote explaining it in DETAIL. Click the link I posted above. Read it and watch the video. Then you won't have to guess anymore. ;)]]></description>

			<description><![CDATA[Point being, still, that it's all theory at this point. That could indeed be the explanation. The reality could also be the exact opposite. We just don't know, though this information seems contradictory to what little we do know. I suppose we'll have to wait until a good tech site does a deeper analysis, like Anandtech. Personally I hope this is untrue, going up in power consumption at this point would be equal to going backwards. Indeed, I were considering a 7950 just to reduce my power draw - and hopefully noise output - myself.]]></description>

			<description><![CDATA[Damn you 800 letters limit. I'm not saying it's a rule or anything, but usually more ALU functionalities , means more transistors, which means bigger ALUs, which usually results in higher power consumption. If 7950, with 1920 shaders, really consumes more than 225W, then one possible reason might be the above theory. Although it's just a theory and the reason might be a completely different thing.]]></description>

			<description><![CDATA[Ok, but do stream processors, or should I say ALUs, remain the same throughout generations? Don't they lose or gain functionalities ? AFAIK they change. That's what I gather from GPU analysis articles. This, for example: "The 4 slim ALUs handle all of their old tricks, so each is capable of 1 FP MAD/ADD/MUL or 1 INT ADD/AND/CMP, as well as integer shifts. Cypress adds to its slim ALUs the capability to do single cycle 24-bit INT MUL whereas before no INT MUL support existed at all. ... There's also FMA support, which will bring benefits versus a simple MAD when it comes to precision loss introduced by rounding involved in the latter." http://www.beyond3d.com/content/reviews/53/8]]></description>

			<description><![CDATA[Point being that we know what it's aiming to do, just not how. The 2048 stream processors are supposedly arranged in 32 clusters, which make up the new GCN units. To me that doesn't sound like each stream processor is significantly different, just that the macro-arrangement and possibly how they're exposed to the rest of the hardware is. Which shouldn't require significantly more die real estate. We just don't know yet.]]></description>
