AMD A10-5800K Capable of 6.50 GHz over LN2: Company
AMD's new A10-5800K "Trinity" APUs, launched earlier this week, are capable of extreme overclocking, something similarly-priced Intel processors can't claim, according to Adam Kozak, desktop products manager with the company. According to Kozak, the roughly $150 A10-5800K are capable of 6.50 GHz overclocked speeds, when augmented with liquid nitrogen cooling.
Overclocking capabilities give AMD's sub-$150 chips such as the A10-5800K, A8-5600K, and A6-5400K an edge over similarly-priced Intel chips. The cheapest overclockable chip from Intel's current lineup is the $220 Core i5-2500K. Based on the "Trinity" silicon, the A10-5800K ships with clock speeds of 3.80 GHz, which go up to 4.20 GHz with TurboCore. The chip features an unlocked base clock multiplier, which makes overclocking possible.

Thats what some folks forget when they compare just performance v intel, like the article implies i think?
Cherry/ golden chip may hit > 4.5Ghz on air... but most don't, not at temperatures/voltages that have a long term chip lifespan.
I will agree that 4.5 is painfully easy.
4.8 on water is quite easy... more requires a good board and good chip... and proper cooling.
I have seem many a dead SB and IB from those trying to make their chips into golden chips...
Stable for a few months then not even stable at stock...
(as a folder I value stable clocks over sky high...though seeing the sky is nice occasionally)
Might go for a low-profile/low-TDP build with the A10-5700 and my youngest would use that system (nothing more demanding than Open Arena). Or if the A10-5800K can be easily pushed on air, might build it for my wife with an HD 6670 for Crossfire.
And as most people here know, clock speed means nothing comparing architectures. That's the lesson we learned then, and I'm afraid will learn again.
For example:
"...Overclocking abilities give AMD's sub-$150 chips such as the A10-5800K, A8-5600K, and A6-5400K an edge over similarly-priced Intel chips..."
So... basically our chips clocking higher = better than intel chips. which is most likely BS.
Its probably a great chip - just as long as you dont read the shiny box that promises magical super unicorn performance.
A 2500k will do 4.7ghz and have the graphics power of potentially 6450 (1875mhz) smooth and easy on air for $220.
A 5800k may do 4.7ghz and have the graphics horsepower of ~6570-6670 (> stock gt640) smooth and easy on air for $150.
2500k is probably around 15% faster per clock on the cpu.
5800k is probably around 300% faster (depending on bw dependency) on the gpu.
It's all relative to what someone is using their computer for and I fully realize that, but as a realistic package for many users, I like those ratios. I can't say I would notice 15% cpu performance most of the time, given when I ran my 2600k stock which would be fairly similar, but certainly recognize how much the iGPU in SB doesn't hack it no matter what you do.
Add a $50 gfx card to a 2500k, and you have the performance of an OC Trinity.
Add a $50 gfx card to a 5800k, you have the performance of a $100 graphics card.
Suddenly the performance/$ is completely skewed, and you have a half-decent gaming setup for less than the price of a 2500k.
Oh yeah, and from experience if you ever watch a 24fps video using SB, be ready for pain.
I am happy with the video performance/options of NI, Trinity is probably similar/better.
I think it is truly difficult to argue against AMD's realistic-usage proposition.
I did not (in any way) say that it's a bad CPU (or it's a bad buy, etc). We could have a conversation where we compare the pros and the cons of the two chips, but that's definitely not what I meant in my post.
The marketing guy was talking about overclockability, and mentioned the i5-2500k. If you overclock, you do it to gain extra performance, and that's something what we can measure. That chip has significantly larger TDP at 4.7Ghz, not to mention that how much more you gonna need to get 2500k@4.7Ghz-ish benchmark figures, because you gonna need a lot more, and that's not gonna be smooth nor easy for sure, let alone the extra noise and electricity bill what will come with it.
APUs are not for serious overclocking, it's a product which currently used for entirely different purposes. They might be the future of course, but we are not there yet. AMD knows that the cheaper and cooler i3-3225 with its HD4000 is targeting the same segment and does everything what the target audience is looking for, so they (understandably) try to emphasise on the overclockabilty of their chip to shift focus from the competitor product, so some people might find it harder to "argue against their realistic-usage proposition"
Again, please don't get me wrong, Trinity APUs are really useful nice products and they can be the better choice in many builds. All I said is that they are hopeless against performance monsters like the SB/IB-K series.
