Four Core Core i7-1165G7 Tiger Lake Beats Eigth core Ryzen 7 4700U Renoir in Geekbench
You can say a lot of things about Geekbench, the first, for whatever reason everything leaks there. The second, the number never are rather trustworthy. Ergo, therefore, this news item should be taken with some disclaimers.
Both Intel and AMD have a few products in the works and one of each surfaced on geekbench, Intel's Core i7-1165G7 4-core / 8-thread (Willow Cove) processor based on the 10 nm "Tiger Lake-U" pulls ahead of the Ryzen 7 4700U (Renoir) processor, which has eight cores. The Geekbench comparison shows two Lenovo laptops, one with the i7-1165G7, the other a 4700U. The difference in favor for Intel is almost 37% in single-threaded performance while being 0.5% faster in multi-threaded performance (again, 4 versus 8 cores).
It paints a weird picture, also with the Ryzen 7 4800U the 8-core/16-thread chip ends up 22.3% faster than the Core i7-1165G7 in the multi-threaded (Hyperthreading).
Thanks SOTN for the news subkmit.
Core i3 8130U (Kaby Lake-R) won't get four cores but does get a turbo - 12/29/2017 07:30 PM
Notebooks and laptops with a Kaby Lake-R generation Core i3/i5 CPU are available. The new budget Core i3 Kaby Lake-R sticks towards two cores, however, there is something new going on, this proc rece...
Core i3 8300 with Four Cores and Eight Threads Spotted - 08/03/2017 09:38 AM
We've stated a couple of times already that AMD is stirring up the market on every segment with a processor. The recent Ryzen 3 series for example are all quad-core processors, historically Intel alw...
No Dual and Four Cores Zen CPUs all 6 and 8 core - 05/05/2016 07:38 PM
At t least that is what sources from bits and chips in Italy say. If true then with the perf boost and 8-cores, the Zen chips do look mighty good. AMD will produce just the 8 “Zen&rdquo...
Four core Fusion APU comes with 55W TDP - 06/29/2010 10:37 AM
Last week we already mentioned that AMD is working on a low cost and low power Fusion processor. This week Fudzilla mentions that a 55 Watt part is in the works as well. AMDs Fuzion processor will be ...
Athlon X2 7750 - Enable and unlock four cores - 04/26/2009 09:23 AM
A while ago we already reported that on some AMD Phenom II 720BE processors the 4th core could be enabled. It seems that the very popular Dual Core AMD Athlon X2 7750BE has

A unreleased CPU using a new node beats an already released one by 30% on single-thread? That is good, but not super surprising.
We have come to expect rehashes of CPUs for what, almost 5 years now? I'd say that's the least they should be doing, and about time.
Meanwhile, AMD is also cooking Zen 3, which will probably be released before tiger lake and probably offer more cores, while supposedly having 15% better IPC than current Zen 2.
So yeah, time will tell if these numbers are even good.
15w-25w zen 3 isn't coming out for some time though, obviously the desktop ones will beat this at double the TDP.
I'm more curious to see how RDNA performs on an SoC honestly.

I like how much cache has this willow cove. Finally a bump in l1 data cache since long time and also a hefty bump in l2 cache.
That could justify some of the perf increase.
Remember, the bigger the cache, the slower it reads and writes. A bigger L1 cache is only a good idea if your instructions don't fit. To my understanding) HT allows for 2 separate threads to run on the same core (and therefore share the same L1 cache), so it's tricky for Intel to find the sweet spot. Well, thanks to all the security vulnerabilities regarding HT, I assume they increased the L1 size to address some of the performance losses due to mitigations, so perhaps the L1 is meant to be more split between each thread.
