*** AMD "Zen" thread (inc AM4/APU discussion) ***

if thats the price for 6c what are the quad cores going to be.

also where was that from, didnt think they had released anything about them yet.
 
Good news if true. I'm hoping for some decent prices on the quads too.

I'm quite happy with the current pricing to be fair, but part of me is still gutted that the pound has gone down the pan. We would likely have seen a ~£280 1700 before the exchange rate tanked.

Ryzen cpu have an overclocking tool similar to wattman for rx480.
You can adjust each cpu core,and proberly save a profile for each game.

I think it is because CPC said they saw a single core overclock of 5GHZ on a qualification sample.

Edit!!

OFC,I am not saying that is possible.

I'm surprised there haven't been any recent leaks of retail cpus if that's possible? Surely it would be something to shout about?

lowest 4core/4thread Ryzen starts at 129$, then you add about 25$ for each new model untill you reach 1600X, they have like 6 or 7 models between R3 and R5

Canard PC when they reviewed Ryzen, you have part of the review posted by cat the fifth, they got their hand on an engineering sample and without NDA, so they posted a lot of infos including single core overclock they hit over 5Gh on air

Until it's done on a retail I think expectations need to be tempered?

Yeah.
Perhaps the 4 cores will come in around £170.
Intel will have to respond with price drops and then we might get real purchasing dilemmas for 4 core products potentially between Intel and AMD. With 6 and 8 cores, possibly not so much. AMD should have the edge.

EDIT: Seems there are a lot of 4 core Ryzens planned so bit more complicated. AMD seem to be able to pitch some quite low priced. Good stuff.

Did I not say in a round about way for so long overclocking is not high. This includes Memory oc.

If I say I won't buy does anyone think 5g is possible with anything other than ln2.

To me each sku within the range is simply amd binning internally for higher boost clock stability. So further headroom is very limited.

The Cpu is great at multi thread for sure and certainly rendering and such tasks.

With respect. Yes indeed you did.

If they are anything like me those who buy these chips don't think single threaded performance achieved through high Mhz is better than having twice as many threads for the same money, actually, most of us use these chips for more than just DX9 World of Warcraft getting 80 FPS instead of 70, a lot of us think 'while no doubt true' is just a whole lot of old ####.

The gaming experience in most cases actually is going to be the same because unlike Bulldozer these AMD chips have a similar IPC to Intel, if not even a little better, its just the 10 or 15% clock rate differences that sets them apart and because of that yes you may get a few more FPS on a 7700K than you will on the 1700X the 10% less on the later is not really going to make a tangible difference, and most are interested in more than a few usually old games where the 7700K may do that bit better, in that, which is just about everything else the AMD chip will humiliate the 7700K, for the same, or even a little less money.

Repeating the fact that Skylake clocks higher does not make any difference to our thinking here, we already assume it if not know it for a fact, the RyZen chips are still much better all round chips and Intel have far too many invested people around them to get to the truth all the time.

Oh and one final thing, i have the know how and tools to come up with a game that will max all threads on a 4 Core CPU and bottle neck the crap out of a mid range GPU, don't think for a second these things don't exist because its technically difficult, it isn't, it doesn't exist like that because even higher mainstream end in game development is still thought of as 4 threads, so game are simply not evolving to make use of more available power, thank you Intel.

With a bit of luck that will now change.

All three processors are the same, they all have XFR technology. The X varients have higher boost clocks hence the X, otherwise all three CPU's feature XFR and the only difference is clock speeds.

Someone who was at the event seems to be saying that specifically the X is a feature that hasn't been mentioned yet, which means it's unlikely to be just the boost. Because lets be honest, you could have a 1700, 1800 and 1900 with no X and each would have higher base and boost clocks. There is specifically a 1700 and 1700x, then a 1800x, if X means more boost.... where is the 1800 with less boost, etc.

An as yet not specifically mentioned feature that X cpus have that the others don't makes more sense, though that feature may be, unlocked voltage to 2v while non X cpus have max 1.5v or something, so you can only get an extreme overclock on an X edition, or maybe just an overclockers warranty, which intel used to or still offer don't they.
 
That ‘X’ prefix denotes support for eXtended Frequency Range (XFR) which allows a number of the CPU’s cores to operate at up to 1 multiplier bin higher if thermal and power threshold budgets are not saturated. The main difference between the 1700X and 1800X is related to operating frequency. The 1800X is essentially a cherry-picked chip that fits a more desirable voltage-frequency curve and can be expected to overclock higher than its 1700X counterpart.

AMD’s SenseMI is used on all Ryzen 7 CPUs and the entire Ryzen product stack has unlocked multipliers that can be utilised with the correct motherboard. 20MB of L2+L3 cache is available.

So in the first paragraph they say the X means XFR and states in the article the 1700 has no XFR support. Then the last paragraph states that all Ryzen CPU's have the SenseMI tech, but SenseMI tech includes XFR???

I think the media outlets are making it up as they go along.
