Ryzen released 1 hour ago and amazon/newegg are already flooded with reviews from people who don't own the product. Why has this brand identity culture become so rampant the last 5-10 years?

Also Ryzen performance is more or less what we expected based on the leaks from the last few months. One reviewer did a dolphin test (not anandtech unfortunately) and showed its IPC to be comparable to ivy bridge in dolphin so you're still better off with an Intel cpu for dolphin (which are also a lot cheaper). Also it's harder to OC since it has so many cores. As far as in general the IPC varies from application to application ranging from the same to 20% lower than kaby lake. In other words IPC is between ivy bridge and kaby lake depending on the application. Generally its single threaded performance is similar to haswell. PC games still run better on Intels platform but this time not by a wide enough margin to actually be noticeable. Frame times are very close but not quite on par with Intel. Of course where it shines is multithreaded performance where it is often on par with 8 core Intel chips but not always, depending on IPC. The 8 core Intels are still better overall, but only by a small margin. I will continue updating as I read more articles/data.

I see zero reviews on newegg.

Gonna wait till i get home to read the anandtech review, should take me about 3 days to finish.

@ExtremeDude2

My bad. I assumed if it was happening on amazon it would be happening on newegg. I think newegg has put a block on early reviews.

Woooow. Ok, disclaimer, this is not confirmed. According to a report, AMD is delaying Vega, so they are going to make the 500 series Polaris... and just rebrand the old cards. And they are keeping the numbering, just applying an overclock! Literally, according to the report, the 580 is a 480 with an 80mhz overclock.



I mean, wow. When nvidia or AMD rebranded in the past, they lowered the numbering at least. Delaying vega is not really surprising, but bumping the number up with a rebrand a year after the 400 series launched, and a lateral rebrand... Wow.

I really hope this turns out to be false, because if true this is really sad of AMD.

They spent all of their R&D funding on Ryzen

@MayImilae: I think the rebranding was worse in the past. Some R7 and R9 are GCN 1st gen cards, and the weird HD 7790 is GCN 2nd gen card. So the naming scheme went one step up, but the tech went one step down in some cases.

The performance advantage in Dolphin for Intel I've heard has to do with the speed of the Cache on Haswell and above CPU's along with instruction sets used. Is that true or is that totally bogus (or somewhere in between)?

[NaturalViolence]

We have no way of knowing for sure but that's plausible considering cache bandwidth was doubled for both L1 and L2 on haswell.

If this is true:

then there still might be some hope of Ryzen. If Windows is actually load-balancing across CCXes right now, then Ryzen cpus can't use their cache properly. That would explain really bad single core performance. On the other hand, if this was true, amd would have pushed for a driver or whatever update, so it was fixed on Ryzen release.
