Ryzen 3000/Zen 2 IPC ~ Sky Lake IPC. Ice Lake IPC = 1.18 * Sky Lake IPC. Tiger Lake IPC = 1.1 * Ice Lake which makes Tiger Lake CPUs 30% faster than the best currently available AMD CPUs. Remind me with what Intel can't compete again 'cause I've lost you there. Intel doesn't have the node to produce these CPUs but AMD does not have any nodes at all - it outsources their CPU/GPUs to TSMC. Get your facts straight before spewing another portion of fanboyism. WCCFTech should be a place to go for you if you want to talk to like-minded people.
That calculation is a bit off - you're working with relatively low percentages, so every bit counts, and Zen 2 has (
according to AnandTech's Spec2017 testing) a ~6.7% IPC advantage over Skylake (9900K tested). That shrinks Ice Lake's 18% increase to a much smaller 10% lead, and Tiger lake would then just move the needle a bit more to a 21% advantage. (Not to mention the rather skewed comparison of Tiger Lake - an unlaunched, future product not arriving until at least late in the year - to "the best currently available AMD CPUs". Wouldn't the fair comparison be to compare architectures available around the same time frame?) Add to that the rumored 15% IPC increase for Zen 3 (at this point this is just as believable as any Tiger Lake numbers, as neither are official nor confirmed in any way) and we're looking at a very slim lead for Intel. Not to mention that Ice Lake on 10nm clocks
lower than Zen 2 on 7nm in the same power envelope (the 8-core Ryzen 7 4800U has a 1.8GHz base clock, while the 4-core i7 1065G7 has a base clock of just 1.3GHz), meaning that AMD can make up for any IPC deficiency by a slight clock speed lead. Tiger Lake is likely to clock higher on 10+, but so is Zen3 on 7+. Launch timings of course don't match perfectly, so who has the advantage at any given moment will change, but we're not looking at a situation where Intel is likely to run off with the IPC lead again, nor a clock speed lead.
Currently: Intel IPC = 1 (except for ULV mobile where some SKUs are 1.18), AMD IPC = 1.067; either 6.7% advantage AMD or 10,6% advantage Intel, depending on the SKU. AMD Zen 2 mobile chips are not yet out, Intel Ice Lake desktop chips are likely never arriving. Intel 14nm clocks higher than AMD/TSMC 7nm, which again clocks higher than Intel 10nm. Intel 10nm is
still struggling with yields given how much more common 14nm Comet Lake is than Ice Lake (Comet Lake also outperforms Ice Lake due to higher clocks).
Later this year/early next year: Intel IPC = ~1.299, AMD IPC = ~1.227; ~5.8% advantage Intel. No idea about clock speeds, but expecting Intel 10nm+ to bypass TSMC 7nm+ sounds unlikely.
This looks like a tightly competitive market, which is exactly what end users should want, and would mean that features and price rather than raw performance becomes the main points of competition. This is excellent, and going to be very, very interesting.
