Xevipiu, I was giving you something while you were doing the lapping on the i9. But I have several questions:
Where do you work to be able to measure the height of the die with that precision?
How do you know that you have lost some transistors?

200 micros, what a pass... and I don't have time for anything

@krampak brings us a new micro again. This time it's a Pentium 4415U, which is a two-year-old Kaby Lake.

With the typical 15W TDP of the U series, the 2 cores with HT and 2 Mb of L3 cache, it's a modest micro intended for office laptops. Its performance does not stand out from the rest of the laptop models and is on par with the i3-6100U, a supposedly superior model a couple of years older.

And in the end, if there are no major changes in CPI, the TDP is restricted to those 15W and the gate width is not reduced from 14nm, we find CPUs that have essentially been offering practically the same thing in recent years. In the end, the characteristics of that Pentium are a copy of those of the i3-6100U except for the i3's extra mega cache. However, it is also true that if we look at the list of processors similar to the Pentium, to find similar performance in previous generations, we have to go up the range. So I suppose that is an advance.

It is precisely from some NUCs that we put together that usually come with the i3-6100U, which these have come to me with these 4415U.

@rul3s and @JuezDred bring us a Zen+ from 10 months ago. It's a Ryzen 5 2600.

In short, it's a processor with 6 cores and SMT that runs at 3.9Ghz and dissipates 65W. The closest processor is an i5-8500 as seen here. Both perform equally in multi-thread, although in single-thread, the Coffe Lake has a noticeable advantage over Zen+, both being roughly the same age. As expected, SMT helps a lot in this case, as at a frequency 12% lower than Intel, it manages to match the performance in multi-thread. Basically, both architectures seem to be very close and get similar performance per MHz, just as both get a similar score in efficiency (performance/TDP).

Unfortunately, there is no data in mode 0, where AMD usually gets better scores (at least in Zen without the +). The closest AMD we have data for is a Ryzen 5 1600X. In this case, in multi-thread, the Zen+ has a not insignificant advantage, although in single-thread, both are basically the same. Considering that the Zen+ runs at a slightly lower frequency and has a TDP of 30W less, it seems that there has been an important improvement between generations.

A few days ago I uploaded the results of an industrial Skylake PC. It has a Celeron G3900TE with two cores at 2.3GHz. The overall performance is pretty fair and I guess it's enough for tasks like office work. Being a fanless computer, I'm surprised that this particular model has a TDP of 35W when the U series is only 15W. With the cost of the machine, I don't understand this skimping. But in the end, its performance turns out to be comparable to the U series precisely, being the closest a i3-6100U. Nothing particularly noteworthy about this CPU.

On the other hand, a certain @ignacio00 has uploaded the result of an AMD FX from the Piledriver era. As a plus, it has passed the AVX test, so at least it has a decent set. On the other hand, for a micro at almost 4GHz, with 6 cores and a TDP of no less than 95W, it turns out to be comparable to Intel's run-of-the-mill portables like the i3-6006U.

[krampak]

I have uploaded another variant of the HP NUCs that we receive. After moving from the 6100U to the 4415U, we now have one with a 7130U. I think there was some Windows process that was not up to par, but the result is quite consistent with the previous ones.

[cobito]

@krampak Here is the datasheet.

It seems that this time it does represent some improvement because the differences between the 6100U and the 4415U are imperceptible. It's not that it's a huge leap, but at least it's no longer listed as the most similar CPU. With this update they've made, there's an improvement of between 15 and 25% depending on the number of threads and mode, which is quite a lot given the current times.

Overall, the processor isn't bad considering it's an "i3 U". I'm surprised that in single-thread it gets the same performance as an i7-4720HQ, which is only two years older and which, with twice the cores, has a TDP three times higher.

This weekend, @krampak has brought us a new portable micro to our database: a Core 2 Duo T6600.

This processor turned a decade old earlier this year. Its performance is comparable to processors from the era like the famous Core 2 Duo E6600. But it doesn't look anything like or remotely current.

The most exotic micro that's similar is a Xeon E5504, which has the same single-threaded performance and with double the cores gets double the performance. Now that yes, with a TDP 2.5 times higher. In that Xeon it seems that even double the cache compared to the Core 2 Duo T6600 doesn't seem to help. And the most curious thing is that both are separated by only 3 months. Either the Core 2 Duo came out very good or that Xeon doesn't even move backwards.

Apart from that, nothing more to highlight.

@krampak Well, that is a strange error. It is supposed that this Windows uses the same kernel as Windows Vista, although it is also true that I have not tested all the components of the test bench under Windows 7. And to be honest, I do not remember what the launcher was doing exactly. I will be away these days, but when I return I will take a look, if only out of curiosity to know what is going on there.

[cobito]

@krampak Today I was able to review the source code. The launcher does nothing but detect that the selectable mode is executable by the processor. If there is an error, it sends a signal to the window to display an error. Otherwise, it launches the execution of the test bank. That is, at first glance it seems that the CPU does not have the selected repertoire. Under normal conditions, if it is not compatible, an error message should appear in the window, but it seems that Windows 2008 manages the issue in a different way.

Initially, the failure comes from trying to execute µinstructions that this Xeon does not understand. Did you try running it in mode 0? I see that this Xeon model has support for AVX2 but I don't think the NT 6.0 kernel supports anything beyond SSE3. Reading around a bit, it seems that R2 is needed to access the vector repertoire. So that must be the problem. And in fact, that may be the reason why the error is not being displayed in a normal way (I had never tried running the graphical version on such an old Windows).

On another note (and with apologies for the delay; this week I couldn't do more), we have new micros.

More than a week ago, @garfield brought an i7-8750H with 6 cores, HT and a TDP of 45W. Today @rul3s has brought us what seems to be its twin brother from AMD: an Ryzen 5 2600X. I don't know if they have agreed on what, but this one also has 6 cores, comes with SMT and was launched on the market the same month and year as garfield's i7.

As it seems that the cover is a bit sad, I'm going to publish the mini-comparison here.

You're right, it works in SS3. In AVX and AVX2 it fails

[Magog]

I have uploaded a Dell 7470 with an I7 6600U.

Best regards.

[krampak]

I just uploaded another HP NUC like that (I'm still finding variants xD), this time an i3 4030U.

[rul3s]

I just uploaded a 2600x something a bit higher in revs

How less curious

Ah, I haven't said anything, I didn't remember that the 1800 is 8/16.

[cobito]

Upon reviewing, I realized I had an interesting lineup of micros

@magog I was going to say that this model was already validated by @Namiga a year ago, but I went to compare the results and it seems that yours is quite a bit faster. Namiga's was at 2.8GHz when it ran the test and yours was 18% faster: at 3.3GHz. This can be attributed to limitations in the manufacturer's BIOS or something running in the background. But your CPU is pulling double the multi-threaded score. Looking at the performance per MHz of the architecture, it seems your result is quite close to other models like the 6500U, so your submission becomes a pretty representative sample of that model.

In another CPU lineup, Namiga brings us a Ryzen again, this time with integrated graphics. It's a Ryzen 5 2400G, a Zen (plain and simple) with 4 cores, 8 threads, and a maximum frequency of 3.9GHz. The composition of single and multi-threaded performance as well as in modes 0 and AVX2 doesn't resemble any AMD CPU and the Intel CPUs that appear in the comparison are very varied: from an "exotic" i5-5675R to the i7-4790K and all with big differences. Surely, the most interesting thing about this CPU is the integrated GPU although unfortunately we have no way to evaluate that. To not leave the analysis too bland, perhaps it's interesting to see what it resembles in each area:
· In single-threaded mode in FPU mode, the closest is the Core i3-7100.
· In single-threaded mode in AVX2 mode, it resembles the Core i7-4790
· In multi-threaded mode in FPU mode, it has some similarities with the Core i7-7700
· And in multi-threaded mode in AVX2 mode, it almost matches the aforementioned i5-5675R.

And to finish this round, as @krampak said, he's back with his NUCs. We are faced with an i3-4030U, a Haswell from the U series that was discontinued not too long ago. As a good U series, it comes with its TDP at 15W, which won't be a problem for its performance because its 2 cores (with HT) run at a fixed frequency of 1.9GHz. The processor turned out to be the slowest CPU in AVX2 mode of all the ones we have. In fact, the list of similar CPUs seems to have gotten a bit mixed up with the comparison. In summary, in FPU mode it's comparable to processors not of very high range of the old Wolfdale architecture. In AVX2 it's even below an AMD A9, which is nothing more than a Exacavator portable APU. That's right; the last one on the list. Although not to be too unfair to Haswell, that APU needed practically double the frequency to achieve similar performance.

Edited: By the way Krampak, the Xeon from Windows 2008 without R2 I added to the database but it shouldn't appear because the frequency was measured incorrectly in all tests (it measures 800MHz). I don't know if it's a problem with that Windows, that the machine is excessively loaded or some hardware issue (high temperature, incorrect configuration, etc).

After this piece of news we will have to see how the 1903 affects the Ryzen with this benchmark.

I understand that in theory it shouldn't affect much, since the novelty is that instead of separating the threads as much as possible to avoid hot spots, which hindered communication between threads, now they will bring them together as much as possible, occupying a CCX before starting to "deposit" threads on the other, because of the way games are developed. From how the bench should work, I understand that with independent threads that don't communicate with each other because of the type of calculation they have to perform, the result shouldn't vary much.

[Fassou]

I passed the test to a laptop that's a few years old, and I see that the micro (4702MQ) was not, and it links to the datasheet of a Pentium
