From a quick read, in case anyone is wondering, this is built on the latest-gen 10nm process which is a refinement on the previous 10nm process.

Apparently he doesn't perceive much real world performance difference between the 2 machines. I'd say the same thing about upgrading from an i7-6800K (2016 Broadwell-E) to a Threadripper 3960X. Barely a difference (my main work is a ~250k loc c# solution, also a similar medium-ish sized Angular app).

I went from a i7-4770k to an AMD 3900X and my workload is almost identical. The difference has been absolutely night-and-day

For me, the perceived performance improvements have been always slower. The only mind blowing perf improvement was when I first used SSD, Thunderbolt/USB-C. The other things like RAM and CPU are hard to notice unless we are doing some computation heavy tasks like video editing.

I also notice windows starting up faster than it used to before, but I know its because of the SSDs and caching. These 20% and 30% YOY improvements are simply not worthy to invest in because the returns are negligible for me.

This article is really a lot more informative with synthetic benchmark numbers. https://www.notebookcheck.net/All-core-4-3-GHz-at-28-W-Intel... Intel's 4 core parts getting within 3% of AMD's 8 core parts, 20% lead in single core perf.

Those are pre-sample non-final numbers. We didn't post Intel's numbers because they are unverified.

Yeah. But I think 4 cores at 50% higher base single thread vs 8 cores is actually a pretty reasonable tradeoff for many workloads. If they managed 6 cores though... would have been pretty awesome. I hope this delivers. I'd hate to see Intel go down in flames.

Right, that's perhaps a glaring omission. Last year's (Ice Lake) i7-10710U was a 6-core, 12-thread part with a TDP of 25W. https://ark.intel.com/content/www/us/en/ark/products/196448/... But it's entirely missing from this announcement. Seems like a regression.

10th Gen that ended in a U are Comet Lake (14nm++++) 10th Gen that ended in a G with a number are Ice Lake (10nm)

The article doesn't appear to mention the price points for these new chips. I also find it interesting that the TDP maxes out at 50W. Is Intel entirely focused on the medium/low end or is there a problem with doing higher TDP chips using the "SuperFin" architecture?

These are laptop processors - Intel also didn't release 1000-unit OEM pricing in our prelim info.

Note that the 28W TDP number is for 3.0 GHz base clock. 4.8GHz turbo would be 50W.

I would like to see the measured power usage attached to those results. Depending on the laptop and its TDP the OEM has set, these results can vary quite a bit.

4. If they previously had a 60Hz monitor, and upgraded to 120Hz or better. This improves both motion quality and latency. When poorly designed software makes you wait multiple frames, halving (or better) the frame time makes a noticeable difference.

Can't confirm that. Used 144 Hz display and was not really able to tell a difference. I run benchmark and there were very subtle difference, but 60 hz is more than enough for me. Now 4K resolution is a big deal.

You must be immune to the "soap opera effect" on the newer TVs as well.

A few years ago I accidentally left my laptop at work, and couldn't program over a long weekend. I had a first generation raspberry pi kicking around so I pulled that out, hooked it up to my monitor, installed nodejs and git and got to work from there. It took 700ms or so for my server process to even start on a r.pi - I'd noticed a brief delay on my laptop, but it was so awful on the pi that I ended up spending the…

In Chrome (and I'm guessing other browsers) you can go into the network tab and slow down networking. I don't think there is a similar option for CPU perf. There are several race conditions in many webpages related to waiting for video or images to load. Tangentially my late 2018 i5 MBA feels sluggish compared to my 2014 MBP. Simple things like switching windows are noticeably slower and janky. Unfortunately my 2014…

> I don't think there is a similar option for CPU perf.

I believe there is an option in the Performance pane to throttle the CPU in Chrome.

And heat up, unfortunately.

I'm completely fine with it getting loud and toasty when I push it, but the 5300M and 5500M in the 16" MacBook Pro ramp their memory clocks up to max as soon as two displays are on, even when idling. This results in a constant ~20W power draw that destroys the battery life, has the fans constantly audible, and makes the top case above the keyboard uncomfortably hot.

Apparently similar issues in desktop AMD cards have been addressed via driver updates, but considering whoever is responsible for updating Mac GPU drivers never actually does it, I'm not holding my breath.
