Nobody talked about DDR3 2133 at any voltage.

Plus you know as well as everyone else that no OEMs will touch anything that isnt a standard. Dell/HP/Lenovo/Apple is not gonna sell office and home PCs with overvolted memory. And only a fool would buy overvolted memory anyway. And that includes 1.35V chips overvolted and overclocked to handle 2133. OEMs dont want they either.

To use (proper) 2133Mhz memory you simply have to pay extra. And its not cheap.

You keep evading to answer the question, where does AMD says that it only support 1.5V memory ???
You were replying to monstercameron saying he bought a 8GB DDR-3 2133MHz at $70 and now you are talking about OEMs ???
Not to mention that OEMs buy memory at different prices than the retail you quoted earlier.

why is that? quick burn out?

Where did I say AMD only supported 1.5V?

To use 2133Mhz 1.5V simply got a significant premium over DDR3 1600Mhz. And JEDEC is 1.35V and 1.5V.

So heres a question, is the 7850k going to be slower or faster then the 8320 FX series?

You are comparing 2M/4T with 4M/8T. Plus lack of L3. It will be slower. And can be even down to ~half speed.

Just compare a FX4xxx with FX8xxx. And you got a rough estimate.

Kaveri has undoubtly much better MT scaling but the FX can use cores taken from different modules when no more than 4 threads are needed hence
somewhat negating a part of the 7850K IPC advantage.

the same could said for many products with amd components, still doesn't invalidate it for comparison. I am saying this as an openly biased AMD apu fan. If AMD can't surpass intel with their massive gpu tech advantage then they are blind...then again the vast majority of the market won't care either way.

Intel can make Iris Pro with tons of eDRAM for a few reasons. Chief among them that they can afford to spend resources on an extremely niche performance product and they have a ready customer for that product in the form of Apple. That second one being a very big driving factor behind the Iris Pro, not only is it a ready customer for the product it's also a customer Intel very much wants to retain.

AMD has neither of those reasons to make an eDRAM version of Richland/Kaveri.

There is very little relevancy in comparing AMD APUs to Iris Pro SKUs. It's about as useful as comparing a consumer Intel i3 CPU to an Intel hexacore E series CPU.

don't want to nitpick but iris pro isn't just a desktop part. The desktop is one thing but there is also a battle on the mobile front where AMD does have a disadvantage. I still maintain that iris pro is a valid comparison or as valid as comparing kaveri to a more expensive i7-4770k+gt630 or i5-4670k.

Same applies to mobile, extremely improbable there is a premium OEM customer knocking down AMD's door for a $250+ eDRAM SKU. Heck, I doubt there is an OEM enthusiastic to add even ~$50 of overall cost for a simpler to produce GDDR5 capable BGA AMD APU.

Being a B2B rep for AMD must be a frustrating job.

Imo, AMD compared the A10-7850K to the i7-4770K to soften that ~$20-25 price rise over Richland top end. If they were promoting mobile comparing their top end mobile A10 to the i7-4950HQ would be less flattering in terms of performance delta but even more drastic in terms of price difference.

There is also the availability discrepancy, Newegg for example has no Iris 5200 mobile product available.

Then why did you mentioned 1.5V memory when anyone can use 1.65v the cheaper 2133MHz Memory with AMD APUs ???

Anyone can also overclock. Chip their cars and whatever. But the huge wast majority doesnt. So what 99% does is relevant, not what you do.

When AMD benchmark with 2133Mhz memory, its well aware that it got a price premium for OEMs to implement. Hence a hidden extra cost to even get that performance.

It degrade alot faster. Its your own choice.

You could most likely just have bought cheaper 1333 or 1600Mhz memory and overclocked/overvolted it yourself.

DRAM degradation? Do you have any study on that? And what is a point when there is a lifetime warranty anyways?
overclocking is not guaranteed. You may aswell get a sticks that cant go 10Mhz over spec speeds.

I dont know what are you trying to say, 99% will buy the cheaper 2133MHz 1.65V memory than the more expensive 1.5V.

Or are you trying to say that 99% will buy the more expensive 1.5V memory ??

People want stock products. Not overvolted, overclocked whatever. This is what OEMs sell.

I know you want to advocate for cheap overvolted, overclocked and out of spec memory to portrait it all in a better light so there isnt a price premium to pay.

You are joking right ??? 1.65V memory is stock, with life time guaranty. What the hell are you talking about ???

1.65V is not stock. To be stock it would have to be a JEDEC standard and actual 1.65V chips produced at the fabs. Its not any.
