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

This is not true, you conveniently miss the third variable - the current. Higher vcore doesn't necessarily mean higher TDP, hence the guy is right with his question.

Well you can do some very simple tests.

Increase vcore on either cpu/gpu, keep other variables same such as clock speed and load, and you will see more power used and more heat created. There may be other variables at play, but vcore is a very important one.
 
On power consumption.

12nm 2700X 8 core 16 threads: 104 Watts
14nm+++++++++++++ 9900K 8 core 16 threads: 204 Watts

7nm 3800X 16 core 32 threads: ??? Watts, what do we think Participant?

Participant:

In isolation, the Cinebench demo showed a good chunk less power for performance parity with Intel, so I don't see "hotter and sweatier" happening. Also, if that parity was not achieved with IPC then it was achieved with clocks. Hardcore nerds will be disappointed the IPC didn't go up, but who really cares if the performance is there.

In isolation, the Cinebench demo showed 8 cores on a single chiplet with the full package laid out to support a 2nd. You wouldn't make a potentially structurally and electrically uneven package without the intention of adding another chiplet. You also wouldn't make such a layout just to cram in a dummy die. And add to that Lisa Su's coy remark of "you'd expected us to fill that space", I suspect we'll get a 12 core model at least. Not having a 16 core would be a disappointment though.

So the only real unknown is pricing. Everybody is expecting a bit of a bump to cover R&D and the increased core counts (should each tier get a count bump), but as discussed repeatedly it is not in AMD's interests (read sales, market and investor suicide) to price gouge or charge Intel money, even if the performance is there.

135W

7nm gives half power for same performance, so slash 2700X in half: 52W. Now double the core count and we're back up to 104W. Now factor in some fudging because these things are never linear, and also we still have package to displace all the heat generated. Sap on a generous fudge and round the numbers for aesthetic nicety; 135W.

They didn't state power consumption but heat/temperature which are not replaceable metrics.
7nm is denser which could lead to temperature issues but based on the AMD demo the power consumption seems very low so there's no obvious reason to be concerned.
The low power consumption is one of the standout features for me and with 7nm+ being touted as more power efficient that helps as it's denser so that helps to keep temps in check.

Yup, that is the apparent TDP of the Chip,

And you're also right in what else you said, that CPU demoed thought to be the 3600 was using half the power of the 9900K in the same run.

Although I know the leaks pitch the 3800X at 125W and 3850X at 135W, I'd still hit those numbers based on loose logic. Because it is logical.
 
It will be interesting to see what % of the TDP is made up by the I/O die being 14nm, especially on those SKU's with two CPU chiplets, after all the I/O is going to be working harder so it will be slurping more power.
 
3600X looks sweet, I suppose what will I will be looking out for is how high XFR takes the chip in all cores under gaming load (moderate utilisation 30-60%)., if it can get to 4.6 I can see myself reacting.

On 2600X gaming all core load is 4.15ghz only 100mhz below its peak single core 4.25ghz. (and thats on stock cooler).

Would have loved a 3600GX chip. IGPU with 4ghz base and 4.8ghz max XFR.
 
mmm keep looking at the table above and cringe and the naming scheme .

specially since AMD has mirrored Intel to allow uniformity slightly and those that are familial with intel to jump ship to AMD easily enough . Plus ryzen 1000/2000 has already established a naming scheme to which intel is running into their own issues with 10th gen adding more cores .

Make more sense for AMD to keep scheme the same

athlon - 2 cores
Ryzen 3 - 4 cores
Ryzen 5 - 6 cores
Ryzen 7 - 8 cores
Ryzen 9 - 12 cores to match and beat intels 9th and 10th series
Ryzen 11 - 16 cores to rub in the salt - specially intel's 9900k 8 core and 9900x 10 core get confusing along to different platforms

dont have a feeling ryzen will drop 4 cores because its budget friendly , and an office pc doesnt need cores as standard . heck 2 cores and 4 threads is fine .

time will tell i guess
 
Don't like Ryzen 11 :p plus there's no need if the tiers get a core bump. Athlons get 4 cores, the rest match the leaks.

Now if the tiers don't get a core bump then I don't reckon we'll get a 16 core, because mixing 12 and 16 cores in the same Ryzen 9 tier might get confusing. Unless 38xx is 12 core and 39xx is 16 core if needed?
 
Don't see them releasing a 4-core 7nm chiplet design CPU, it will end up costing more than the equivalent 14nm version due to the I/O die (for now). Athlon should move to 4c/4t, with APU, in other words a 2200G. :)

Yeah, maybe they will do monolithic 4 core 4/8 thread Athlons with small iGPU's for lower end laptops, the Pentium segment of Laptops.
