Anandtech review of the i7-1185G7 has been released > https://www.anandtech.com/show/16084/intel-tiger-lake-review-deep-dive-core-11th-gen

This is a mobile 28w 4 core 8 thread CPU, on a 10nm+ process, which is clocking to 4.8Ghz.
Dr. Ian Cutress describes the single thread performance between Intel/AMD as so:

Against the x86 competition, Tiger Lake leaves AMD’s Zen2-based Renoir in the dust when it comes to single-threaded performance. "

Rocket lake, the desktop equivalent of this CPU, should be very interesting. 4.8Ghz for a laptop chip isn't too bad, with a 28w power target. Imagine a 120 TDP version of this CPU's single target performance in games! :eek:

Considering Intel's 10th gen CPU's (which are using 5 year old Skylake and 5.5 year old 14nm) are already slightly faster than AMD's Zen2 CPU's, when Rocket Lake launches, the lead Intel take in gaming is going to be huge!

That said, I'm probably only going to upgrade when I can buy either an AM5 or LGA1700 platform next year, so it will be between Intel's Alder Lake and AMD's Zen4 in 2021, it will be interesting to see how Zen3 improves over Zen2 in a few months.

Mmmmmmmmm, perhaps you should have read the complete review before posting

"The new Tiger Lake stills falls down against the competition when we start discussing raw throughput tests. Intel was keen to promote professional workflows with Tiger Lake, or gaming workflows such as streaming, particularly at 28 W rather than at 15 W. Despite this we can easily see that the 15 W Renoir options with eight cores can blow past Tiger Lake in a like-for-like scenario in our rendering tests and our scalable workloads. The only times Intel scores a win is due to accelerator support (AVX-512, DP4a, DL Boost). On top of that, Renoir laptops in the market are likely to be in a cheaper price bracket than what Intel seems to be targeting."

Hmm, perhaps you should have read where I'm excited about the single thread (and thus gaming performance) of Intel's desktop chips, based on the same cores? :)

I'd still buy a renoir CPU from AMD over the Intel chip, as it's clearly the better option for laptops when you consider the overall package. I'm just talking about the core single thread performance improvements, that will translate over to the upcoming desktop CPU's.
 
Rocket Lake still on 14nm?

Yeah, but with the new architecture back ported to 14nm.

I'm guessing 20-30% more IPC over Comet Lake (which is still Skylake). All depends what clocks they can get to.

Alder Lake is where they'll likely completely leapfrog AMD in gaming, as that's gonna be 10nm, with the big and little core design (chiplets).
