AMD - Zen chitchat

threadripper PCs up for pre-order at overclockers.co.uk https://www.overclockers.co.uk/pc-sy...og%2Cfs-097-og

and if you click the 'configuration options' on the page, you find out the 16 Core 1950X 4.0ghz retail. is £159 more than the 12 Core 1920X

also says 'all options due in stock 31/7'


that's some confirmation of released ate and prices at least.

A TR CPU has been delidded, revealing 4 dies. I wonder if final retail CPUs will be the same? At least they're soldered! https://videocardz.com/71252/amd-ryz...our-ryzen-dies

Scan have got retail Bristol Ridge APUs up for pre-order. A8-9600 for <£60 might give the Pentium G4560 a run for its money, particularly if Intel truly are restricting supplies.

I can see BR being a fairly limited production run, with them not wanting to build up too much inventory before the Ryzen APUs.

It seems the Core i3 7350K is now £100. Still a fail since you need a £100 Z270 motherboard and probably a £20 cooler on top of that.

You can get a Ryzen 5 1400 and that ASRock B350 motherboard Bagnaj97 mentioned earlier for similar money.

There was a comment with this image which I found hilarious on that site. Thought I should give it a little more exposure here.



Nice to see Bristol Ridge APUs for the desktop. APUs are sorely needed on AM4, in my view they will spur the development of more mITX boards. Fingers crossed.

If only two dies in TR are used, what's in the other two? Has AMD actually found a use for dies where all cores are defective?

A B250 board will run it fine, but it's still £20 more than the 1200 for the whole package. And with the 1200 OC'd to the same speed as a 1300X, the ryzen will beat the i3 in every gaming benchmark bar one in the hexus review.

It will run it fine but you can't overclock the CPU or run the RAM past 2400mhz. Remember, reviews will be testing these in Z270 motherboards too.

If you are comparing locked to locked,then it gets worse for the Core i3 7350K,as an A320 motherboard is still cheaper than a B250 and remember not all H110 motherboards will run the Core i3 7350K out of the box.

Just read a bit more about it - AMD have apparently confirmed that Threadripper uses only two active dies. Also I think that's still an ES, so not necessarily representative of retail parts. Truly defective dies wouldn't make it to packaging, so maybe they're just shifting some packages with 1 or 2 lower binned dies attached if they didn't make the grade e.g. on TDP for EPYC? IIRC this sort of binning is usually carried out after packaging, but I'm not so sure for MCM. Packaging yield itself should be sufficiently high for that not to be a consideration though i.e. due to dies broken during soldering.

Leak of the Ryzen 5 2500U APU:

I was lookign around for cheap DDR4 for my Arock 350 pro4 and I came across this https://www.techpowerup.com/235076/p...-am4-platforms.

Which led to this: https://s3.amazonaws.com/patriotmemo...zen_062217.pdf

After watching the corsair 2666 DDR4 on Amazon jump from £119 to £135 in just two days I bought some of this patriot viper elite stuff for £109 at 3000 MHz the first set had a dead stick so I had to get a replacement. But the second set turned out great and I have it running at 3333 MHz with out changing any thing else, I have not tried to see how far I can push it beyond that.

Just a note for anyone who is on the hunt for some decent ram at lower prices. I have seen it for £90 direct from the patriot website but unsurprisingly it is always out of stock so good luck if you try to get that route.

I managed to get a 16GB kit of Crucial 2400 back at the end of 2016 for just over £70 knowing I was planning an upgrade and seeing prices on the up. Turned out to be one of my better decisions! The same kit is now ~£130.

Perhaps more depressing is a similar 16GB Corsair 2400 kit back in April 2016 cost just £61 from Scan!

It's just absurdly expensive now, often the single most expensive component of some more budget-oriented systems now! Thankfully I should be able to ride out the storm for now, with manufacturers ramping capacity of both new NAND and DRAM in the near future.

Sadly the RAM compatibility is still the biggest downside with Ryzen - not with normal speed DIMMs,but with the higher speed stuff. It is no doubt technically out of spec,but the issue is Intel runs out of spec stuff with better compatibility and Ryzen seems to show big improvements even upto 3200MHZ/3466MHZ depending on the timings.

Over on AT, member dooon The Ryzen "ThreadRipper"... 16 cores of awesome"]found[/URL] a Planet3DNow! post about other Threadripper SKUs:
http://www.planet3dnow.de/cms/33149-...er-epyc-zp-b2/
Implicit is that Threadripper is based the B1 revision and not the B2 rumoured for EPYC.

Which they got using this key

That article links to an official AMD.com PDF
https://www.amd.com/Documents/AMD-Product-Master.pdf

Wonder what price the 1950 non-X is going to be? And the price of X399 boards. The actual chipset seems to the same as X370, but I think one of the earlier articles on Threadripper or X399 implied that the monster socket is very expensive but that might change with a ramp-up and/or be mobo manufacturers trying to justify high prices.

EDIT: in case AMD pull that PDF, here are the YD19* entries:

Hopefully they have a way of limiting supply to stop supplies being hoovered up by people who are likely to dump half-broken cards back on ebay as soon as the price fluctuates a bit. AMD did mention something about delaying the launch to ensure a good supply for actual gamers.

I suppose, if it does turn out fairly lacklustre for gaming, then it will at least ensure some volume both for Vega and HBM2 memory. That, and if it turns out to be very efficient, it might keep miners away from other cards.

It could be nonsense though, of course.
