People with Windows 7 most likely also have very old computers, and might want to update them, but not the OS.

In general, I agree with you, its absolutely not big of a deal, but not every case is the same. It might be a problem in some situation, for some people.


One more thing: It appears that 8C/16T CPU with 65W is actually 3.1/3.7 GHz version. Expect exactly the same level of performance, as i7-5960X.

macOS, on the other hand, might have to support it if Apple uses it in the iMac - or eventually Naples on the nMP.

It will be interesting to see which product Apple chooses.

There is also Raven Ridge that would go into the MacBook Pro.

This is a completely overblown non-issue.

Someone buying new Windows PC would either buy a pre-built system and get Windows 10 along with it or build a PC and buy a copy of Windows 10 for it.

You mean OS X Leopard?! It wasn't macOS back then. Details, I know.

It's not that Windows 7 is that old that no more support is needed. And a lot of people still use it. I do at work, I have to.
Something similar happened with SKL but M$ I believe reconsidered.

About Ryzen 4C/8T. Don't expect to clock that SKU higher than 8C/16T. Not because of tremendous design of the chip, but huge flaw that does not allow the chip to clock very high. Its because of second CCX, that is in the die. The good side of this is that the chips will be cheaper to buy.

Compare this to situation with Raven Ridge. 4C/8T CPU with 35W has 3.0 GHz base clock, 3.3 GHz turbo, and has GPU stuck to itself ;). All in 35W package.

I honestly am most excited about the APUs, this turn. They most likely will allow to some degree building simple computers with just few parts(SSD, MoBo, RAM, APU, Cooler, PSU, Case, and thats it).

Timmy fooled you. The spelling was changed, not the name.

You can keep running Windows 7 on old Windows PCs just as you can keep running macOS 10 Leopard on old Mac PCs.

Newest Windows PCs will require Windows 10 just like newest Mac PCs will require macOS 10 Sierra.

And stop with the "M$". If anything, under Timmy, Apple deserves the $$$ more than MS.

So I've heard.

Quad-core Summit Ridge supposedly have even lower clock than the octa-core Summit Ridge because the former is made from poorly performing binned parts with four cores disabled.

Do you think that that is a bad thing?

Do you realize how expensive CPUs would be if only perfect chips were sold?

The business model depends on testing the chips to find out how many fully functioning cores there are, and what speed can they be pushed to and still be reliable.

"All cores work at high speed" go into the $$$$ SKU, "half the cores work at half speed" go into the $ SKU. That's the way it is.

You need to have a limited number of SKUs, so chips with 5 functional cores will be sold as 4 core CPUs with the 5th core disabled. Chips with 7 functional cores will be sold as 6 core CPUs with the 7th core disabled.

This is true. The economics of chip making depend crucially on maximizing the yield, the %-age of chips manufactured that can actually be sold. Especially when starting a new process (a new chip family, a higher resolution like 14nm, etc.), the yields can be less than 50%. They improve over time as the process is improved.

Ryzen R7 8C/16T clocked at 3.4 GHz, I7-5960X OC'ed to 4.7 GHz, i7-6900K OC'ed to 4.2 GHz, i7-5820K OC'ed to 4.8 GHz, compared in benchmarks.

The clocks on the graphs are wrong. First picture show true clocks, and why 5960X, would be faster than 6900K.

Its also Single thread performance.

Let me put a little more coal into hype train ;).

Cheapest 8C/16T will be 350-399$. 6/12T core CPUs will be between 200 and 300$. 4C/8C will be between 140 and 200$.

So yeah. This is thermonuclear price war, started by AMD. And Intel is in GIGANTIC trouble. AMD being behind, have made GIGANTIC leap forward, in front of Intel. And they made this, with two pennies, using scissors, paperclip, and concrete. Competition is back in x86 market. And boy we have funny times, ahead.

And one, last bit: I told ya! :p

Edit: Proof that it is not Fake:

One thing I have learned is that people are so desperate for information that I can post some completely fake things on Reddit and people treat it like completely verified facts. :D

Yes, you can, and you are welcome to do so, for entertainment. Every fake news about Ryzen has been debunked very fast. Its much easier to do with CPUs, that with information about GPUs.

This CPU is in the database. All other CPUs are in the database of the benchmark. Its absolutely not fake.

I never said that the benchmarks are fake. o_O

They could be, but I don't make them.

Passmark appears to not read Turbo clock from Intel CPUs.

6950X has max Turbo boost of 3.5 GHz. Ryzen CPU was running on 3.4 GHz, stock clock in the benchmark, because of the Motherboard. Effect?

2022 for Core i7 6950X, 2046 for Ryzen.

The IPC appears to be exactly between Haswell/Broadwell.
