Design changes in Zen 2 (CPU/core/chiplet only)

This discussion is interesting, even if everything is just hypothetical, it is a good read. Thanks guys! Question, why no SMT3? I have seen SMT4 and SMT8, but SMT doesn't have to double for each step. If they add another AGU and double the FPU (dual 128-bit like bulldozer), then SMT2 might not...

AMD RYZEN Builders Thread

If you are using USB3 hubs/devices only, but most USB2 defices currently can saturate a USB2 poort. Not a problem if it is a direct connected device. But you do not want to use those on a hub. The annoying thing with USB3 is that it has a legacy USB2 connection, so on a USB3 hub, all the USB2...

New Zen microarchitecture details

Well, where is AVX2 and AVX512 going? If someone is willing to optimize for it and find some usefull usecases, it gains traction.

New Zen microarchitecture details

Maybe calling it 'really a disappointment' is comming off a bit to strong, I think it is neat to include everything that is needed for a notebook or NUC like device. Anyway, sure there will be mini-ITX boards that meet your requerements. Just look at the ASRock FM2A88X-ITX+ for example. That...

AMD Ryzen (Summit Ridge) Benchmarks Thread (use new thread)

That is indeed what people will see, that an octa-core Zen isn't a match for a quad i7. But if you look at the 6900, at the same clocks, the 6900 would be just 4% faster in that collection of games. I guess switching to AMD with just a 4% difference can be justified with a nice discount.

Yes? As the chart says: "chart for illustrative purposes only" ;) (On the other hand, the minimal steps in that chart should represent 25Mhz)

Yes that is the point, Intel is confident in what they have. Wouldn't they do more if they were afraid of Zen? Like a 120watt version or something. Unfortunately, that is true :(

And a 6700k that is allowed to consume 5% more power called the 7700k. Intel knows that AMD probably can't match the IPC and the clock, so with most games still favouring quad-cores, the hello effect is already countered.

New Zen microarchitecture details

I can image that Apple would sue everyone for using transistors in a chip... But I'm not saying that AMD needs to copy stuff from others, just look at good examples :) However, going back in time, this post from @raghu78 1,5year ago, could have some truth in it. Most of the discussion about...

I'm just hoping he transferred some of the ideas of the Apple Ax(X) cores to the Zen and K12 core designs. As those cores have some impressive single-thread results: http://browser.primatelabs.com/ios-benchmarks (Calculating it to IPC doesn't make it any less impressive, only that the OS isn't...
