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. Intel's goal was to focus on clock increases, so the instruction per clock is apparently not much changed. From looking at the tables, the whole line of processors appear to have nicely improved one core max clock speeds, which should hopefully help single core performance,…

This is why I haven't plunked down the money to go to the 2019 model when my early 2013 model isn't quite half as fast. The only thing I will be missing is that this laptop won't be able to run the new OS coming out in the fall.

Not too interesting for those interested in high performance desktop and server offerings. The fact that Intel's only new releases on 10nm are AMD did a really smart thing with their processor designs. Instead of doing a large monolithic multiprocessor like Intel (which may be able to eek out some extra performance due to optimized wire placements), they use smaller chiplets. This results in requiring no manufacturin…

> That's my understanding, anyway -- correct me if I'm wrong. Since these are mobile processors your understanding is incorrect. What you've described is what AMD did on the server & desktop side. But on mobile, to hit the power efficiency targets, AMD stuck with the single monolithic die. And it's a decently large one, at that: https://www.anandtech.com/show/15381/amd-ryzen-mobile-4000-m... So no AMD wouldn't yield…

If I understood lend000 correctly:

> The fact that Intel's only new releases on 10nm are Their argument was that, had they followed AMD's approach, they would be able to produce desktop and server chips despite being yield-limited to "<= 6 core" per chiplet.

>(the 10300-10900k are all the same chip with different parts turned off due to manufacturing errors) Wow. Is this a relatively new phenomenon, or something that's been the norm in processor mfg for a long time? I know that the Ks were usually just binned/higher tested chips so they'd unlock those and charge a premium for them, but the idea that they're disabling parts of the die and separating the chip offering that…

insert the ohio astronauts meme

wait, it's all just binning?

it always has been.

Since 2017 (and much worse in 2019 version) the (15") MBP dGPU overheats whenever it is use (including whenever external monitor is used) due to a driver bug. Stay away

Worked swapped out my mid 2015, 2-core 16gb with a 2019 8 core, 32gb, and this machine is night and day better. It's so much faster at every task I throw at it.

In 2015 the 15" was 4-core.

I agree. I don't feel much difference between the 15" MB-Pro i7 4-core from 2014 and the i9 8-core from 2019. The i9 really isn't noticeable faster on single core. Instead it gets hotter and its fans starts sooner. So I recommend keeping the old one if you have it.

Wouldn't newer ones be more power-efficient as compared to the older one? I remember reading a post on HN which stated the OP buying older, high spec hardware for cheaper than latest one and almost all comments pointed to power-efficient thing

The dGPU is much hotter due to a no-downclocking driver bug that is worse on a chip that is more powerful, and bad software that wastes CPU cycles had more cycles to waste.

From what I see the problem is that the newer Macbooks are slimmer and have less efficient thermals. So the processors are more efficient, but the benefit gets lost by shipping them in smaller enclosures and on top of that smaller batteries.

I'd love to see the new processors and RAM in a 2015 enclosure. Makes me wonder whether someone has attempted to hack it together.

I run a pretty big VDI environment — my observation is that the the latest gen stuff on Xeon is about the same as the Haswell era gear, and slower for some use cases. We’re actually planning on running that gear longer and moving people with more memory needs to newer gear with more memory — it’s all about the maintenance cost curve. We can get much more memory now with the same density, which offsets the CPU suckage…

Is that network constrained?

No, we’re blessed with lots and lots of network capacity. It’s possible to have a peak demand that would saturate one of the fabrics, but our usage patterns allow us to avoid that.

The disabled parts are the broken parts.

I just switched from a laptop with spinning rust and an Intel Celeron N2830 to a laptop with an SSD and a Ryzen 5 4500U. Each of the six cores is several times more powerful than the old CPU. Now I get why so many developers build sites that were unusable on the old one. Even a JavaScript-heavy site is as performant as a static site now. They don't even realize what they're doing to people stuck on old low-end comput…

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 MBP has an no longer supported NVidia GPU by Chrome/Firefox/Photoshop so I may have to upgrade but I know it will basically feel no different than what I have except I'll have the touch bar which I'm not really interested in.
