AMD Zen 2 (Ryzen 3000) - *** NO COMPETITOR HINTING ***

[Impy77]

Excited for these but can anyone explain this (even tech tubers are totally ignoring this...)
3600X is 6c 12t and 95w tdp
3700X is 8c 16t and only 65w tdp!
Basically same clock speeds as well!
Is 3700 golden samples eg no supply on release?
Some thing to do with number of chiplets? Could 3700 be two chiplets with disabled cores giving larger area for heat dissapation but added latency because two chiplets?

Love to hear people's thoughts. I'm no expert but this seems to be an elephant in the room for this release... OCUK experts tell me what's going on...

Im going to guess the 3600x is 8 cores that failed QA, so they disable 2 cores and have to push 95w through it to get it stable.

The 3700x is the 8 core that passes QA

The 3800x is the highest binned 8 core that passed QA and it gets higher clocks

Surely that just means it'll throttle more?

So the 3700X if loaded on all 8c (16t) will run at the base clock rather than boosting.

Whereas the 3600X loaded on all 6c/12t might well be boosting much higher and maintaining those speeds.

In any case the benchmarks will be the real arbiter of which is better at any given task.

Without benchmarks everything is guesswork

I've been thinking long and hard about what to do. Currently thinking about buying a 1700 for £140, then in 2 years I should be able to upgrade to a 3700 for £140. But then my total spend will be £280. So may as well spend an extra £40 and buy the 3700 now. But then I cant bring myself to spend that much on a CPU, especially when it could be just £140 after 2 years. So then I start thinking about getting the 1700 for £140 again. I'm just going round in circles in my head. Dont know what to do.

IANA-electrician, but you push volts through it to keep it stable, no? Not power.

The TDP (as someone here said recently) is the minimum heat dissipation needed to run within specification (as somebody here explained some time ago).

The actual heat dissipated is going to be much less in light workloads. And the chip could considerably exceed its TDP briefly in terms of power drawn.

 

[Stephanie Peterson]

It is interesting with how the differences in the two 8 cores especially will play out, might end up having the lesser one be just as capable as long as you squeeze enough Volts though.

 

[humbug]

I've read this four times and can't figure out what it means!

"Developed in a game engine running on an Intel CPU"...

Eh?

They use Desktop computers to develop games on, ones that are not at all different to the ones you and i have.

Eh?

maybe the fith time?

also intel compilers have never been helpfull to AMD and Nvidia gives games devs a lot of help (money) to enhance their hardware (often at the expense of AMD hardware). Maybe things will change soon

Yeah but (and I'm not a game dev) I thought the bias came from the compiler?

With many (most?) compilers generating code that runs quicker on Intel.

You make it sound like a game engine is a kind of command interpreter... (I wouldn't know I just make "Hello, World!" programs these days )

Intel's compilers don't apply to whatever game you're playing.

correct

Ignore the boost clocks, all CPUs will go above TDP to achieve that.

Check the base clock.

Same, but was considering going for a 2xxx gen chip. Half of me keeps thinking just chuck in the extra and go 3xxx

 

[humbug]

He makes some good point's here, AMD are still offering much better value for the same performance than Intel, and in fact nVidia if the 5700 = RTX 2070 thing is true.

Guess it all depends on your cooling and the details of XFR/boost (etc), which we don't have at this time.

For all we know AMD could have put in hard limits on power draw so that the 65W cpus won't boost anywhere near as high/sustained.

@humbug not watching any more ***** YT videos. Can summarise?

 

[humbug]

TDP is Thermal Design Power

That's not power consumption, all it is is a recommendation for minimum cooling, its often used, mostly by Intel as something to print on the box to make those who think TDP = Power Consumption think its X amount efficient, for example the 9900K TDP is 95 Watts, ha... ahahaha.... NO!

The way Intel get away with that is print a base clock of 3.6Ghz on the box, at 3.6Ghz the power consumption, and therefore heat output is 95 Watts, but if your MB VRMs are capable of feeding more than 95 Watts and you are using cooling that can dissipate more than 95 Watts of heat it will "boost" higher, upto 4.7Ghz, and in reality the 9900K at 4.7Ghz is a 200 Watt CPU, not 95.
Ryan Shrout, Intel shill extraordinare, on his 9900K review performance benchmarked the 9900K on the best Asus board, but when it came to Power consumption testing, he used the crappiest board he could find, which hard throttled the 9900K to its 3.6Ghz 95 Watt base, and concluded "its a 95 Watt CPU" i propose because with Ryzen at the time showing Intel up for power efficiency they didn't want to get humiliated.

So, the 65 Watt 3700X / 105 Watt 3800X, AMD are pretty good at citing actual power consumption in their TDP ratings, the 65 Watt and 105 Watt Ryzen 2000 CPU fall just inside that unmolested, what i think is going on is on the 65 Watt 3700X the XFR boost is capped lower than it is on the 3800X, to with in the given TDP.

I don't see the point in buying this one Ryzen 9 3900X you might as well wait a few months and buy the 16 core 32 thread one get more for your money.

 

[4K8KW10]

I don't see the point in buying, as well, in order to get more for your hard-earned money, honestly think that if AMD can afford to do this, they are no longer on the road to recovery but safe and secure, and honestly hope that intel’s 3rd Core X HEDT Lineup in the autumn will return them back to the Earth from Mars.

Bit dramatic...

AMD had a great computex. Intel and nvidia on the other hand.
