every time i say the word ryzen to myself i end up here in my head:
it just matches so well

It's ramping production. It will obviously be a higher bin. These samples come from small batches with very little opportunity to harvest higher clocks parts. Also there are things like steppings and process tweaks that can increase clocks.
Lisa seamed confident. She said "base speeds of 3.4Ghz and higher" So there will be parts with higher base clocks than 3.4Ghz.

I only listen to the most awesomest of metalThis is a really good song. Thanks for sharing!

You will probably want to check out Matt Barlow era ICE EARTH (same vocalist as that pyramaze album), then if you like that, Demons & wizards ( same guitarist as ice earth (they also play my most fav song of all time)) and then finally my favorite blind guardian ( same vocalist as Demons and wizards).You should post more metal samples, your taste seems excellent. Following this group on Spotify now

All i need is some one from blind guardian to do a pyramaze album and then the circle will be complete...lol

At any rate I wonder if the 3.4GHz sku will be very highly binned with only very limited supply.
$zen_schedule = launch;
$base_freq = 3400 + int rand();
$conditions_met=0;
until ( $conditions_met ==1){
if ($zen_schedule eq 'launch'){
(if $base_freq == 3400 || $base_freq > 3400){
$conditions_met=1;
}
}
}
lisa says "our horizon processors at launch will have base clock speeds of 3400mhz or higher";
so lets make it clear
Code:$zen_schedule = launch; $base_freq = 3400 + int rand(); $conditions_met=0; until ( $conditions_met ==1){ if ($zen_schedule eq 'launch'){ (if $base_freq == 3400 || $base_freq > 3400){ $conditions_met=1; } } } lisa says "our horizon processors at launch will have base clock speeds of 3400mhz or higher";
It's a pretty much a given it will be cheaper. AMD needs to break the inertia of people buying Intel. Also there is plenty of room for AMD to price the Ryzen for decent margins. There will probably be a top bin gold sample part that's going to be expensive. But I am convinced the main SKUs will be significantly cheaper than Intel.
If AMD was going after the $1k CPU market they would have included quad channel memory. Their intentions are clear, 8c/16t will be sold at mainstream prices. Around $500 or less.
Does rand() return a signed or unsigned int? I kid, I kid
The scaling isn't linear though. At low 3Ghz it could be 2-3% per 100Mhz.. and only .5% at 4Ghz. Which makes sense, because once you remove the CPU bottleneck the GPU becomes one. And most games are optimized for some baseline like 3.7Ghz Intel CPU.The blue graph pretty clearly shows Intel cpus are only gaining max 1.5% performance per 100 Mhz increment. There is no even remotely reasonable clock speed that is going to propel Ryzen anywhere near 6700k territory. Even at 5 GHz it will still lose to a stock 6700k, unless the cpu has otherworldly scaling.

Compared to higher clocked i5s Ryzen looks really solid despite its 3.15Ghz base and 3.3Ghz boost. All these games tend to not scale past 4 cores. In either case it looks very competitive to me.
Let's fact check this
The games tested are BF4, ARMA III, X3: TC, Witcher 3: Wild Hunt, Anno 2070, GRID: Autosport, and Far Cry 4.
How do these games all scale with cores?
Far Cry 4
This game seems to like fewer, but faster cores. Also doesn't seem to respond much to architectural improvements (no difference between 3770K and 4770K, for example). Mainly seems to like clock speed (as the 4960X's result shows, a chip that's 3.6GHz base/4GHz turbo).
Battlefield 4
This game seems to run well on everything, from FX 8350 to 4960X. I don't think this is a good measure of IPC for obvious reasons.
Anno 2070
Hard to tell the difference between the CPUs at 1080p, so GPU limited. Even at 1024x768, it seems that scaling past 4 threads is poor and once again it doesn't respond all that well to architectural improvements (basically no difference between SNB/IVB/HSW at same clocks).
Again, doesn't look like a good IPC test since it doesn't really respond to CPUs with measurably better IPC.
ARMA 3
Doesn't seem to scale well past four threads (3570K vs 3770K result), nor does it seem to be all that sensitive to core perf/MHz (look at how well the FX 8350 is holding up and we know that's a much weaker core than IVB/SNB). Even i7 920 is holding its own despite a big frequency/IPC disadvantage to the newer core.
Once again, doesn't look like a game that's all that sensitive to better microarchitecture/higher IPC.
GRID Autosport
This game seems to respond reasonably well to more cores up through about five cores/five threads. Then it just doesn't seem to care. Big jump in going from 2 threads to five threads, though.

X3: Terran Conflict
This game seems to like IPC/clocks more than anything else, doesn't scale too well with core/thread count (see: 2600K vs 2500K, and 2600K vs 3960X).
Witcher 3: Wild Hunt
This game doesn't seem super sensitive to CPU performance, FX 8350 does almost as well as a 2500K, which does nearly as well as a 3770K.
Doesn't seem like a good test of CPU IPC/performance.
Anyway, so looks like we have a bunch of tests that, in aggregate, probably don't tell us much about the underlying CPU core performance.
We can't really conclude much about relative IPC (single thread perf/MHz) of the various architectures based on this set of games, IMO.
