AMD Ryzen 7 "2800X" Not Part of First Wave

[BiggieShady]

65 W TDP for R7 looks great even for 12nm ...

105 W / 65 W = 1.615
4.35 GHz / 4.1 GHz = 1.06

95 W / 65 W = 1.4615
4.25 GHz / 3.9 GHz = 1.09

So for X models we have 6% more performance for 61.5% more juice with R7 ... or 9% more performance for 46.15% more juice with R5

This is unfortunate. I would definitely go straight to the 2800X if they released it this wave. These days, I don't have the interest to overclock and just want the highest base frequency out of the box that is rated at <125W.

Uhm that is kind of flawed comparison. You are using single core clock and whole chip tdp. X models boosts higher all cores than non-X models(Precision boost overdrive) and that tdp will be reached all cores working rather than single core tasks.

You are right ... that was for single threaded load, if we use low clocks for all cores load, X R7 gets 15% more perf, and X R5 gets 6% more perf ... TDP ratios stays the same because all cores are same.

TDP for AMD is and always has been entirely about the Thermal Design Power and what it will take to cool it. It does not denote a need for more power. So you have proven the new chips will reach higher clocks and generate more heat when they do. Which is exactly how that works for any system that moves something faster than before with no change in the number of moving parts.

I wasn't trying to prove a point ... I'm kinda trying to figure out how they managed to have 65W TDP on R7

Lower clocks, turbo & no (enhanced) XFR2 perhaps? Besides TDP doesn't correspond to much, other than the kind of cooling some chips may require.

Well if you look tpus r7 1800x review single core power consumption for that is very low(64W for whole machine on superpi). So that 65W TDP and 4.1GHz single core is quite easy task. But what do you think is all core clocks for such a chip(Well it's obviously over that base clock of 3.2GHz).

 

[bug]

As soon as I see TDP in the comments I'm like : "Yip, here we go (again)...they think TDP = Power draw". CPU TDP is the maximum amount of heat generated by that CPU. Higher TDP = Needs better cooling. The i5-8600K and the i7-8700K both have a TDP of 95W, but during wPrime testing the i5 consumes 114W while the i7 consumes 150W. https://www.techpowerup.com/reviews/Intel/Core_i5_8600K/16.html

Yeah, I mean any five grader should be able to figure that one out. I mean, just because you have to dissipate 105W, doesn't necessarily mean you're drawing that amount from somewhere. Surely part of that is the pixie dust inside doing its thing.

You got it ...

So that 65W TDP and 4.1GHz single core is quite easy task.

Well 65W TDP for a 8c/16t chip all cores at 100% at stock, they did it with R7 1700 at 3.0/3.7 and now at 3.2/4.1 ... not bad

 

[TheLaughingMan]

In the end, there are too damn many ways to fudge the numbers for TDP and there is no regulation or set rules to govern it. So it comes down to what you can get away with telling your customers and not piss them off. I personally ignore TDP and just overbuild my computer from the start. My CPU coolers TDP rating is something 220W+ so I should be good no matter how far the fudged.

Hmmmm I had planned to get the highest end Ryzen+ CPU on a B450 or X470 Mobo this year as an upgrade to my FX 8350 but if they delay the 2800X by to much then I might as well wait for Zen 2. I can still play all my games without any issues on the 8350 but an upgrade would be nice. What to do....

Tapegate? What does Nascar have to do with any of this?

I'm in the exact same boat. I think I'm willing to do 2800X if comes out, else I may consider the 2700X. All of the games I play also play smooth enough with a 980 Ti. Like you, I will wait for Zen2 if I have to. I am getting some serious upgrade itch though!

They need those dies for the next ThreadRipper. Duh

Seriously, since the current ThreadRipper parts are high-bin 4.2Ghz Ryzen 1 parts, they MUST concisely beat that. My uneducated stab in the dark out of my rear end guess is a fully stable 4.6Ghz 8 core (16thread) Ryzen 1.5 part (all cores, base speed) is nearing the max (might not even be possible) so anything approaching that == reserved for future ThreadRipper.

Also for people arguing about TDP... TDP doesn't mean what you think it does anymore. It used to mean Total Design Power - which was the maximum pathological absolute max power draw you could get a given chip to draw at a given voltage from the socket, it was the absolute max that a given chassis/mobo/socket would ever need to handle for a given part. So old school system could handle TPD you were covered.

Intel changed it to "Typical" Design Power somewhere around ... (actually I can't remember, core 2 era?) ... because consumers/popcorn press weren't (*cough*) informed enough, and it became TDP == battery life. Higher TDP == bad. Also it's where they started seriously competing with ARM, and marketing wise it looked bad.

ANYWAY what I mean to get at, is TDP became an arbitrary measure, since you don't know what "typical" actually IS now.

 

[Basard]

I say they are bringing back the FX lineup. 260w TDP. Included in the suitcase they deliver will be a 360mm AIO.

 

[zo0lykas]

How long you want wait,? And what price drop you want see?
If you fallow new's ram price never will be as 2-3 years ago.

• Wait for tapegate to boil over.
• Wait for RAM prices to cool down.

 

[svan71]

Precisely what I was getting at



That's a five year old CPU @ 22nm you're comparing to now...

Intels CURRENT 8 core is a 140 watt part.

I wish AMD would get their 2700X, and or 2800X..?.. to around 4.5ghz steadymaybe even 4.7ghz boost? That would be some awesome performance? And when I take a look in the past well this is the first time in a long time that AMD has came out with something really good?, and I suspect that they most likely will take these 4 years, and get the most out of them by 300mhz. increments to hopefully down the road be somewhere very respectful so in 2020 we can all look back and remember a time in 2017 when AMD came back with a really good processor so the average guy like me can feel what it's like to run with the group of people that have all that expensive awesome hardware for a little less....? I saved up for 18 months so I could put my Ryzen 1700X in a nice motherboard, ram, and solid state SSD, and it was all worth it.!!! Now I have to save up for the 2700X....??? And the one after that...lol..Maybe?? I don't know if it will happen?, but if AMD goes anywhere close to 5ghz on boost..? Well then they really out did themselves taking into account all those cores...But it would nice if they had one processor that did it....?

 

[purecain]

the 1800x chips invariably had better memory controllers... imo... i seemed to hit 3466 pretty easily compared to others using b-die on this chipset...
imo anyway...

 

[nemesis.ie]

Agreed, mine will do 3600Mhz with the XMP timings it's rated for (Team 3733MHz modules).
