AMD - Piledriver chitchat

[DanceswithUnix]

AMD say Kaveri will trickle out in 2013, properly available in early 2014.

They have also released a new APU, 100MHz slower than the old one. Answers on a postcard as to why they bothered...

I can only imagine they didn't make the cut in binning. 100Mhz doesn't seem a lot of extra headroom, of course, but I would guess these don't clock as well.

[DanceswithUnix]

Nah, 100MHz isn't down to binning that has to be down in the measurement noise when working out the right bin.

I can only assume someone like HP wanted a part that was $10 cheaper to hit some price point in one of their systems.

Tom's says 1866Mhz memory support - the 6800k has 2133mhz. Below par memory controller?

Well spotted!!!

ISTR the 6800K has a specially validated memory controller unique in the line. The OEMs aren't going to care to use such fast memory or pay for the validation, and that is probably enough to force them to release a new chip. Using the old clocks but different memory speeds would be confusing, so knocking a token clock speed bump off would make sense.

I would hope this is an OEM only part, that memory controller has got to be worth the $10 in retail.

BTW,on a side note I saw this:

It seems the TPU main editor talked about an AMD R10 GPU being released to take on the GTX780TI?? Unless he was taking the mickey,that would be interesting!!

Edit!!

Probably taking the mickey!!

Probably but it's still suspicious! If there was to be an R10 it would have to be cherry picked chips from an improved manufacturing process. Nothing gunna happen to soon!

What number would it get anyway, can't get any higher than 290 unless it's 290XT ? Suppose they could go 295 :-\

The R9 290X does not fully boost all of the time,so it makes me think what happens when better coolers come out!

Yeah true, power consumption and nomenclature are still issues though.

More I think about it the more I think it was a joke really, hope I'm wrong.

The thing is that it is challenging Geforce Titan with the stock cooler,even at 4K resolutions where you think the 6GB of GDDR5 would give the Geforce Titan an advantage. With better cooling the card is going to boost to higher clockspeeds,and power consumption might improve too(heat can affect power consumption). Pre-overclocked R9 290X cards probably will compete well with a GTX780TI based cards,especially consider the size of the GPU in the latter and if it ships with 6GB of GDDR5 RAM.

Remember temperature can also have a fair impact on power consumption: http://forums.anandtech.com/showthread.php?t=2200205

So there could be some amount of headroom for clockspeed with sufficient cooling.

Edit: Snap!

But the 780 challenges titan, the titan isnt really a gaming card. Its all about double precision at a bargain price with that card in reality. Despite the fact the nooblet fanbois crowned it as some form of ultimate god of gaming, that card seems to have been a magnificent marketing stunt to make the 780 look like good value.
Bloody worked for a while n' all!

I know it's not always as simple as comparing numbers, and not all compute software will be available for AMD cards, but AMD desktop cards allow 1/4 FP64, vs 1/3 Titan and 1/24 on other current-gen Nvidia cards. Depending on what you're doing, a far cheaper 7970 might be very close to the Titan's FP64 performance.

In other words, sure it's cheaper than their HPC cards, but the DP performance is nothing unheard-of.

Edit: Interestingly though, the 290X is 1/8 - I wonder if that's an artificial limitation or if, like Nvidia with their desktop-aimed GPUs, they've cut back on FP64 execution resources to save die space?

The thing is that if a stock clocked R9 290X is around Geforce Titan performance especially at higher resolutions,and a pre-overclocked GTX780 challenges a Geforce Titan,then what about a pre-overclocked R9 290X?? The R9 290X seems to be operating at clockspeeds below a GTX780 to get its performance.

Then there is the R9 290 which due to its lower TDP should boost higher than a R9 290X as they have both the same coolers,meaning it will be hardly behind.

The thing is non-reference R9 290X cards are going to be faster than a GTX780 especially at high resolution,and I suspect if the they run at lower temperatures power consumption will be less. We saw this with some HD7870 cards,where the hot running ones seemed to consume more power,even with similar GPU voltage.

Regarding the GTX780 pricing it was funny when you saw the same people complaining about HD7970 being priced the same as the slower GTX580 3GB(£425 to £450),were the same ones paying £500 to £550 for the same average performance boost over a £300 HD7970GE. It just shows you how much halo marketing and buzzwords works,and how people are indoctrinated to pay more.

Altera will make ARM V8 chips on Intel's 14nm process.

Wonder how many pages of non-benchmark NDA you would have to sign to get one
