I think Ryzen 4c will be the same. About 4.1~4.2ghz tops .
If you look at Broadwell, it doesn't clock well too like the i7 5775C . The broadwell-E at 6 or 8 cores does not clock well neither. Most likely due to architecture or manufacturing process limit .

Since the R7 1700 can do 65W TDP on a desktop with 3ghz, I'm more interested whether can a 6 core Ryzen end up in a laptop with 45W TDP clocking about 2.4Ghz . Afterall, there is no 6 core CPU in a laptop yet. Only 4 cores for the time being. Not everyone can live with ultrabook with that measly 15W TDP CPU. Power users require 4 cores mobile CPU.

Ryzen runs smoother on games that uses CPU heavily though.

TDP is not the same as power draw.

those numbers look very good.

I vaguely remember an old review video about fx 8350, the reviewer use kill o watt, and get about 380++W full system draw.

Neither vendors advertised their max power consumption. TDP means max power dissipation in heat; and TDP will always lower than power consumption.

Most reviewers simply measure the whole system from wall using kill-a-watt which is very close to absolute value if dGPU is absent and highly efficient PSU is used. To actually measure CPU power, you need to measure currents and voltage for each power rails that go into CPU, which I doubt any reviewer would do it.

Tomshardware did.

Some comparison from other country

just gone back from anandtech forum. very detail discussion! samsung foundry 14nm lpp seems to be few hundred mhz less than tsmc 16nm ff+. Besides, samsung finfet also coming from global foundry. Thats explain why amd oc are currently limited unless they use tsmc or others. Amd gone to samsung, probably because tsmc currently getting busy with apple and nvidia. Only samsung able to provide high quantity for amd.

However, the oc should not be more important than the problems（anandtech site） currently.

ryzen having some issue in light workload right now, thats why gaming are weaker. However large workload will not trigger the issue. I think the problem known as thread shuffling. Thats explain the weird result everyone looking at.

also, it seems like someone at anandtech getting ryzen work(sort of) in windows 7 yay!

So many issues AMD need to sort out, don't know if they can do it before R5 release.

ya, but this is first time amd processor been this complicated. Plus, they are small budget. Consider very good as they can put themselves same league as intel. R5 should roll out on time because quite alot issues can be solve through software later. Community at anandtech site are helping with the problem too.

Nah, AMD should not keeping this trend of "release now, solve later" and we consumer should not courage AMD to do that.

Agreed. Hopefully those small issue will be fixed before R5 is released. I'm expecting the update to come with Windows 10 Creator Updates that is schedule to come on April too.

It seems that Joker fake his bench results for his own benefits.

Joker "responded".

Ryzen superior frametime/minimum frame in gaming confirmed by these guys. Even Wendell somewhat confirmed that with GTA:V that have microstutter present since day one i'm playing it.

around @22:40

Interesting fact about Bulldozer fx8350 vs i5 2500K

In 2012 with 1080p, i5 2500K pull ahead with 10.4% more fps using GTX 680.
In 2017 with 1080p, fx8350 pull ahead instead with 10% more fps using GTX Titan (Pascal)

These shows that modern games and gpus will using more cores in future.
But bear in mind, it took 5 years for this to happen.

He also mentioned about cpu bottleneck, the one which get bottlenecked is i7-7700K itself.
But for Ryzen, its not cpu bottleneck, it due to programming bottleneck, since cpu still have plenty of headroom.

And in the end, Ryzen still delivered almost same performance in 4k/1440p ultra preset and superior min fps than its counterparts.
But one thing for sure good for all of us is that AMD will try to drive the 4 cores become mainstream and we will have to wait and see in few more months.

I always enjoyed videos from Steve @ Hardware Unboxed as well as Tom @ OC3D

A nice video from AdoredTV highlighting on why low resolution benchmarking is irrelevant

Yeah, wondering about that too. Anyway still hoping can overclock comparable to broadwell-e, like 4.4Ghz.

Multithreading in some tasks run slower than single thread due to task coordination and dispatch overhead. 7700 is still better in gaming, however, if other heavy things in background kick up, then more cores will run better as the queue for dispatch is lesser, tasks fed into the core faster
