AMD Ryzen Performance Review Leaked: Promising
French tech print magazine "Canard PC" is ready with early benchmarks of an AMD Ryzen 8-core processor. The scan of a page from its Ryzen performance review article got leaked to the web, revealing three key performance takeaways. In the first selection of tests, Canard PC put Ryzen through synthetic CPU-intensive tests that take advantage of as many CPU cores/threads as you can throw at them. These include the likes of H.264 and H.265 video encoding, WPrime, Blender, 3DSMax 2015, and Corona. Ryzen was found to be faster than the quad-core Core i7-6700K, and the six-core i7-6800K, but somewhere between the i7-6800K and the eight-core i7-6900K.
The next selection of tests focused on PC gaming, with a list of contemporary AAA titles, including "Far Cry 4," "Battlefield 4," "The Witcher 3: Wild Hunt," "Anno 2070," "GRID: Autosport," and "ARMA III." Here, the Ryzen sample was found to be underwhelming - it was slower than the Core i5-6600 quad-core chip clocked at 3.30-3.90 GHz; but faster than the i5-6500, clocked at 3.20-3.60 GHz. The fastest chip in the table is the i7-6700K (4.00-4.20 GHz). The reviewer still notes that Ryzen has a decent IPC gain unseen from the AMD stable in a while.
In the final segment, the reviewers tested the power-consumption of the processor. AMD rates the TDP of the Ryzen 8-core chip at 95W, which was desperately needed from a chip built on the 14 nm node. Here it was noted that Ryzen made a tremendous performance/Watt leap over the 32 nm FX-8370 "Vishera." It consumes 93W, just under the 96W consumed by the Core i7-6900K eight-core chip, and slightly more than the 85W consumed by the 22 nm Core i7-4790K "Devil's Canyon" quad-core chip. The 14 nm i7-6800K six-core chip draws 83W, and the quad-core 14 nm i7-6700K draws 62W.
In all, the reviewer concludes that Ryzen could give the DIY performance CPU market the stir it badly needed, and could give Intel a shake-down, but it boils down the pricing.

Time will tell, and all else being equal in chips with Intel, AMD will have to price lower to remain competitive, and this goes for end users, builders, OEMS and retail.
AMD has fucked up in the past, and that is their biggest problem now. Come out honest, with a matching price/performance and don't fail to deliver on promises.
Also who's to say AMD won't have new CPU's coming down the pike as well I mean it's not like they plan to sit around and do absolutely zero after Ryzen is released. If Ryzen is a success I don't expect AMD to sit still and twiddle their thumbs the way Intel acts like it's been doing every since C2D with very marginal improvements.
So basically one would be wasting ~50% of his precious chip on a useless IGP, that's what I've heard gamers say, & still be getting less than 10% IPC over & above Skylake. Also DX12 will be adopted much faster, because of win10 & how quickly we've moved on from PS4/XBO to a Polaris based GPU powering the next gen of consoles.
P.S. Just to add to that, why do you think Intel never released a 57xxK for desktops? They simply couldn't get Broadwell to clock high enough for it to be a compelling upgrade option over the 4790K, that they made it look like a dud actually helped Skylake is another matter entirely.
Now with Kabylake being named as 7xxxK they're doing this mindshare game, just by renaming the chip they're making it look better than what it is i.e. just a respin of Skylake. But here's the catch, with 97xx they'll have to clock it at or above 4GHz & deliver ~15% IPC gains to make it a more compelling purchase than Kabylake, or get it to clock ~4.5GHz & deliver less than 10% IPC.
There's also this little step they'll have to take with 10nm shrink, we all know how 14nm turned out, & how that pans out remains to be seen. I'm pretty certain however that even if they fail to match Kabylake's base clock people will obviously point towards more cores, you know the opposite of what they're saying today o_O
If I'd be Intel I would certainly be sweating right now because Zen being this good actually throws a spanner into their tried & tested formula of milking the consumers with no competition at bay.
And could mitigate the issue here.

If you didn't want an iGPU, come up to the HEDT platform and play with the big boys. Otherwise, you can meddle with the mainstream and complain. I think they value the majority of their customer base to include an iGPU. :)
My point was that, as someone else pointed out, "21% slower gaming performance at 23~27% slower clocks".
What's really good to see is the 1st and 3rd chart. This 8 core is mostly toward the server market. AMD is nipping at the heals of that 6900k which means even at half the price, like that one leak suggested, its going to destroy Intel especially with the slight power savings.
As you said though, I would like to see a 4 core version, but I think summer is going to be the earliest. I would think that AMD could hit similar clocks seeing at this 8 core sample is already hitting the same clocks as the 6900k (BW-E).
If you look through there, you'll see they tested the instruction latency and through put of Bristol Ridge, Raven Ridge, and Kaby Lake.
It's just a question of what is Intel going to do. If they sit on their hands for a year, like it looks, I think AMD is back in the game. Not Athlon back, but more like K6 back. I think there's too much Bulldozer effect for AMD to jump to Athlon level now, but time will tell.
We shouldn't expect too much of IPC improvements either, since both Haswell and Skylake is just minor improvements over Sandy-Bridge. Intel claims there are great IPC improvements, but that's counting special features like AES acceleration. Skylake is just barely faster than Sandy-Bridge, the IPC improvements in total since Sandy-Bridge is more like 6-15% in total. There is not going to be a major improvement until Intel increases the super-scalar abilities of their design.
They are going to keep the clocks decently high too, seeing as AMD is competitive on the IPC front now; so while no IPC count, you will see core count increase, and this was in the plans anyway.

We all know that its pretty obvious that this new Zen CPU is going to be quick bla bla bla its going to be competitive yay for us the consumers. But what im really looking forward to is the APU's, small form factor PC's are on the rise and to have a little tiny beast that can play pretty much every game out there at medium to high settings and use not alot of power at 1080P now thats what I think will be exciting! Somewhere around i5 performance with a GPU of erm idk just under a RX 460? would be awesome.
