So my 16" has arrived this morning and since I was able to spend a few hours running some basic CPU and GPU tests, and I though I'd share my initial impression with you guys. Please keep in mind that these tests are a) very basic and b) were done in macOS, so it's possible that the scores don't translate 100% to what Windows PCs are scoring, but still, it gives us a basic idea. I will be focusing at the following areas: initial impressions/usability, CPU performance, thermals and GPU performance. As for my testing methodology: I have installed the Supplemental Update and I am using an otherwise blank laptop with minimal software installed and a new user. So nothing is indexing etc.

Model being tested: 16" MacBook Pro with i9-9880H (the 2.3Ghz CPU), 16GB RAM, Radeon Pro 5500M with 8GB VRAM

Quick summary: the sustained CPU TDP is 60Watts, short-term TDP is around 80 watts (up to 10 seconds), single-core max turbo can be maintained pretty much indefinitely, the CPU performance is better than a Dell XPS with 2.4Ghz i9-9980HK and the GPU is a big upgrade of the Vega Pro 20.

Initial impressions: it is almost the same size as the 15", just a tiny bit wider and longer. The thickness is virtually the same. It can fit into a really small backpack designed for 13" laptops (even though it's a tight fit). It feels much heavier than the 15" if you hold it in your hand despite the difference only being 170g or so, but I couldn't notice any difference when carrying them in a bag. The display is larger and very nice. I don't think it is worth the upgrade if you find the real estate of the 15" limiting, but it's a nice thing to have.

The keyboard is ok: so much has been said about keyboards that I think it deserves a separate point. Obviously I need to spend a few days typing on it to get a solid feel of the keyboard, but at the first glance, well, it's a perfectly ok keyboard. If feels like a hybrid between butterfly and magic keyboard, with slightly less stable keys than butterfly but noticeably more key travel. I couldn't compare it to the pre-2016 MBP keyboard yet, will do so next week, but it certainly feels better than the 13" 2014 model I had to briefly use last week. So yeah, I guess the keyboard is ok. Butterfly is a more precise keyboard for me and I think it's easier on the fingers (since you need to use less pressure), but let's see how I feel about it in a couple of days. Having the the escape key back is nice. Overall, I like the new Touch Bar design more, it just looks neater. A funny detail: since the keys now rise much higher from the body, it is much more difficult to tap the Touch Bar on accident. So I guess that solves this.

The CPU: finally let us get to the interesting bits — performance and thermal management! To look at these things, I used Cinebench (both R15 and R20) while monitoring the output from Intel Power Gadget , nothing too fancy.

In multi-core Cinebench R20, the MBP with i9-9880H scores steady 3280 points. I did six consecutive runs and the result was always the same ±2 point. It is actually impressive how consistent these results are. Similarly, the R15 multi-core results are steady 1400 points. The CPU power draw is levelling out at stable 60W (15W higher than all 15" MBP I've seen) and the clocks stabilise around 3.1Ghz (with promised nominal clock of 2.3Ghz, which is not too shabby). I'm sure that there will be people who claim that it "throttles" since it is not running on maximal boost, but people are weird.

To put these results in perspective, this graph might be useful. The nice thing about the graph is that is shows where the scores stabilises (and thus where the sustained performance is). Most laptops start out fast but then drop down after second or third run. And some of the scores are just plain weird. For example, an Asus Stix Scar III is reported to have the R15 multi-core score of 1400, but when we actually look at the graph is clear that is stabilises somewhere around 1260. Similarly, the Dell with5.0Ghz 8-core CPU (see the graph) has the average score of 1300, but the graph looks much sadder. Go figure.

So how does the i9-9880H in the 16" MBP perform? With consistent 1400 points it actually does very well. It seems to outperform any laptop of its size and weight, save for MSI Creator P65 (with the same CPU) which performs similarly. And it can even outperform a 3.3 kg HP Omen 17. Of course, it's not the fastest laptop out there. An MSI GE75 Raider 9SG is still 15% faster, but that is a different beast (I mean, look at this heatsink)!

Single-core performance is less interesting I think. Suffice to say that I got steady 436 points in Cinebench R2 and 180 points in R15, which puts it at the same level as any other laptop running the same CPU. It runs at steady 4.5 Ghz over multiple runs, which is about the maximum you can expect of this CPU in real-word conditions (Intel would like to top believe that this is a 4.8Ghz CPU but those top 200Mhz are a scam, since they only trigger if the CPU temperature is under 50C. Really Intel?).

By the way the 15" MBP with the 2.4GHz CPU apparently scores 3160 points at it's highest, so we have a clear improvement here as well.

Ah, I know that you people will pester me with Geekbench, so here you go: 1092/6696, which are just in the middle of the aggregate scores for comparable machines. I personally don't think Geekbench is a good benchmark, it just mixes too many things and doesn't really let you understand what it is you are measuring. Using Cinebench is also not the best, but at least I am confident that I know what is happening.

The GPU: I didn't have much time, so this will be brief. In a OpenCL based maximal throughput benchmark, we have a 30% improvement in raw compute performance and 20% improvement in the memory bandwidth over the Vega Pro 20 on my 2018 machine. For a game test, I used Total War: Three Kingdoms, which is probably one of the most demanding games with a native Mac version. I got 30 fps in all high preset running at 1920x1200 — 10 fps more then Vega Pro 20 and without any lag spikes that Vega Pro 20 suffers from when the game is played with large army sizes. This is the same as a desktop 1050 GTX Ti, which does not sound very impressive , but you need to keep in mind that this is running under macOS. I am sure this thing will outperform a GTX 1650 easily with gaming drivers on windows. I have written more about this in this post

To sum it up: make no mistake, the MacBook Pro has always been — and still is — an ultrabook. It is still as small and light as these higher-performance laptops go. But it looks to me like the 16" is indeed shaping up to be the pro ultrabook king — you will simply not find any other laptop that has this performance AND this form factor AND this battery life at the same time. While it is not dramatically different from the 15" model, the improvements are there — and most importantly, it's price/performance ratio has increased dramatically. I'd argue that it is probably a better buy than any other comparable workstation out there, talking strictly price. For example, a Dell Precision 5540 configured similarly to the higher-end MBP is $300 more.
 
Yup, it's a workstation ultrabook, and a really good example of the breed. Razer manages to get more GPU into their Studio, which is at least arguably an ultrabook - by sacrificing a lot to do it (only 6 cores, "battery, what battery - you didn't expect this thing to run very long, did you?", weird configurations).

Everything else (Lenovo, Dell, HP) has more user expandability and more varied ports - BUT the maximum expansion is less than you can buy the Mac with (2 NVMe slots buy you 4TB, not 8, and it has to be partitioned, for example).. The ports are more convenient, but end up sacrificing bandwidth to the Mac (many of them have only one Thunderbolt port). At least for me, the ideal ports would be at least two Thunderbolt/USB-C plus a couple of USB-A and an HDMI port.
 
The only thing I disagree with here is battery life. If you use the dGPU for any length of time, it sucks down the battery. So it's kind of a different machine with a different purpose if you want decent battery life. But a super computer and the tradenoffs are smart.

Oh, of course — same if you are using the CPU for intensive work (again, it can sustain 60Watts of CPU power, so you are looking at 1 hour 40 min of battery lifetime under these conditions. But that is not really the point. The point is flexibility it gives you. You can use this laptop to do light work — software development, writing papers, writing posts on macrumours — and you will get very good battery life. Or you can plug it in and start doing heavy-duty model fitting or playing newest games — it will do it too. The advantage of the MBP was always that is was a jack of all trades: it could do everything and do it with style. And this iteration improves the performance, without taking away all other things that traditionally made MBP great. Obviously not an ideal tool for everyone: if all you care about is performance, you can get something else cheaper, and all you care about is battery, you can get something else cheeper as well.
 
Thanks for the review.

If you have the chance could you confirm:

- Do you have the popping speaker issue?
- Can you compare your screen to a previous version and confirm if colours/brightness are consistent?
 
- Do you have the popping speaker issue?

Didn't notice anything like that. These speakers are seriously impressive by the way, a clear difference from the 15" model (which already had damn good speakers).


- Can you compare your screen to a previous version and confirm if colours/brightness are consistent?

It appears dimmer (can confirm what people were saying in the other thread), but I don't see any issues with consistency or uniformity. Now, I am not a photographer (and frankly, I have no idea about all these things), but the 16" kind of appears to be more accurate to me? I just looked at some high-res high-contrast photography and I can see more detail on the 16" than on the 15", not to mention that 15" has this kind of greenish/yellowish tone to it while the 16" appears truly black and white (not quite OLED levels, but very good). I also looked at some P3 photography (https://webkit.org/blog-files/color-gamut/) and the colours on the 16" I don't know, just look somehow "better"? For example, the red webkit logo example on the 15" has this kind of carroty look to it while the 16" shows it in a straight out popping red.

Not sure if this was of any use. Again, I can only try to describe my subjective impression. I don't know what I am talking about :D

Appreciate the reply. I do wonder why these displays are coming out dimmer... Being a glossy display, the brightness is quite key when in a very well lit/bright area.

Very good report. How loud are the fans?
 
Very good report. How loud are the fans?

Under load, very much loud. Probably even louder than my 2018 15". I don't have a device to measure that unfortunately.

Under normal operation, inaudible. The interesting thing is that since the chassis can dissipate more heat now, it is generally quieter when dealing with quick bursts and single-core operation. For instance, I din't think I could hear the fans when running single-core cinebench at all.

Thank you for the fast answer !
 
Is it possible to turn off the dGPU? I wish they could offer a version of the 16" without the dGPU, like the old rMBP 15", but I guess this is also Intels fault at the moment. I don't know of any company who offers a dGPU-free 15" laptop at the moment.

I guess I just will have to wait for the updated 13", double fans and n o dGPU will serve my modest needs as musicmaker. I just want as little heat and fan noise as possible , a computer that lasts without a dying dGPU at the two-year mark and lot's of storage.

Microsoft (surface Laptop 3 15") - the only problem is by the time you spec it up with 512GB storage you're already paying over $2k, that's uncomfortably close to the 16" Pro given how much less you're actually getting with that machine.

@leman - thank you for the info. Was your machine still caching by any chance? I was kind of expecting CB20 to be in 3600 range. Also - are you able to tell if the CPU is undervolted? The 2.4 on 15 inch looks to be undervolted by Apple, but the 2.3 didn’t look like that.

...any Surface laptop 3 available for sale in here Sweden has the AMD vega graphics chip, isn't that a dGPU or is it what the ryzen chips use for iGPU?
(but it has removable storage, yay!!!)
 
@leman - thank you for the info. Was your machine still caching by any chance?

Now quite sure what you mean by caching, but it was a test user account without iCloud login, with no additional software installed (except benchmark tools), and the background indexing services were not running.

Also - are you able to tell if the CPU is undervolted? The 2.4 on 15 inch looks to be undervolted by Apple, but the 2.3 didn’t look like that.

I don't think I can tell this without having reference hardware, more tools, and way more spare time on my hands :)
 
you didn't mention soldered SSD and memory which is like slap in face, also still problematics T2 chip and same old LCD technology, what a bummer

I don't think I can tell this without having reference hardware, more tools, and way more spare time on my hands :)
Yeah - I meant spotlight indexing. For the voltage - you said it kept 3.1 GHz stable while running CB20, what was the IA voltage? iStatsMenu has it. I really suspect that to differentiate between 2.4 and 2.3 models Apple simply flips a switch on voltage offset on the 2.4.
 
My suspicion is that the 2.4 gHz chip is undervolted, but that's only possible because the chip is heavily binned. Instead of using the best chips to overclock, Apple is using them to undervolt instead. Rather than getting gaudy numbers that can't be maintained in a laptop, they're getting a higher stable speed with less cooling.

Could they be doing the same thing in the 27" iMac? They use the overclocking-friendly i9-9900K instead of the plain i9-9900, then they don't overclock it, nor let users overclock it. What if the 9900K and the 9880HK are "silicon lottery winners" that run well undervolted, so Apple needs less power (and therefore less cooling) for a given speed?

My opinion on the soldered RAM and SSD is that they're a mixed bag. The upgrades are somewhat overpriced, but the design is more reliable. There's no longer a speed or capacity penalty - no competitor offers more RAM capacity, nor yet matches Apple on storage. It's unlikely that future upgrades will allow a competitive design to do things the MBP can't.

This was certainly not true in 2017 or earlier when maximum RAM on a MBP was really low compared to competitive designs (16 GB compared to competitors that had 32 GB easily, with 64 available at a huge price). I think we're unlikely to see 64GB single SODIMMs at or above 2666 mHz, with laptop-friendly power consumption, for a while (and, if we do, they'll be impractically expensive the way 32s were in 2017). Big laptops get to 128GB of RAM, but they use four sockets.

We will probably see 4TB NVMe drives soon. Newegg lists one from a third-tier manufacturer already, suggesting that the Samsungs, WDs, Intels, Toshibas, etc. are only a few months behind. Those only allow some competitors (those with dual drive slots) to almost match what the MBP can do (most NVMe drives aren't quite as fast as Apple's, plus it's two 4TB drives with mandatory partition, not one big 8TB space to partition as desired). Even the (probably relatively slow) 3rd tier drive is around $700 - the Samsungs and such may well be over $1000 apiece - just about Apple pricing. Apple's price for 4TB is competitive with a pair of 2 TB Samsung 970 EVOs or WD Blacks - premium drives to be sure, but Apple uses premium components too. Apple doesn't offer the option of cheaper, slower drives - which is a legitimate complaint...

Under load, very much loud. Probably even louder than my 2018 15". I don't have a device to measure that unfortunately.

Under normal operation, inaudible. The interesting thing is that since the chassis can dissipate more heat now, it is generally quieter when dealing with quick bursts and single-core operation. For instance, I din't think I could hear the fans when running single-core cinebench at all.

FYI you can download the NIOSH app that will be able help you out with how loud the fans gets.
