# PocketBook 740: performance test of the first dual-core pocketbook

Hello! A couple of weeks ago, a detailed review of the company's latest flagship reader,
PocketBook 740,
was published on the official PocketBook blog on Geektimes.ru
. Just in case, let me remind you that this is the top model of 2018, which, among other things, differs from its predecessors by a screen (and at the moment this is the best E Ink screen I have ever seen), a new compact design (the smallest largest reader on the market - 7 , An 8-inch model, comparable in size to 6-inch), support for the PocketBook Cloud cloud service (
review
) and a new dual-core processor.

As you probably already understood from the title of this post, in it I will thoroughly test PocketBook 740 on the speed of work. PocketBook developers at the time of the reader’s announcement spoke of an increase of about 40% compared to previous models. So let's see if they greatly exaggerated.

It is worth noting that at the very end of February, a firmware update was released for the PocketBook 740. It focuses specifically on improving productivity. That is, if earlier it was just fast, now we are promised another tangible increase in the speed of work. Of course, I immediately installed this update and tested it with the latest firmware version.

I will compare PocketBook 740 with PocketBook 626 Plus, which I personally own. This is a typical 6-inch reader of the previous generation. If the PocketBook 740 has a dual-core processor and 1 GB of RAM, then the PocketBook 626 Plus has only one core with the same frequency - 1 GHz - and 256 MB of RAM. For order, I have reduced all the characteristics of these two devices to a table:

Well, let's see who will put someone on the shoulder blades. On the side of the PocketBook 740 - new hardware, on the side of the PocketBook 626 Plus - noticeably lower screen resolution and firmware licked over the years (PocketBook 626 Plus now costs 9,900 rubles, has been sold since 2015 and has survived five software updates).

at

completely different speeds.

Pocketbooks also performed different tasks: PocketBook 740 loaded Geektimes.ru main page in 6 seconds, PocketBook 626 Plus - in 11.

PocketBook 626 Plus consumed 5% of the battery while reading the indicated amount of text, while PocketBook 740 consumed only 2%. A simple calculation shows that in the case of the old PocketBook 626 Plus, a full battery charge would theoretically be enough for 6,000 pages, and in the case of the flagship PocketBook 740 - for those same 15,000. It is clear that all this is very arbitrary, and in the first case it may well turn out , for example, 7,000, and in the second - 13,000. Or 5,000 and 16,000. But the indisputable fact is that the PocketBook 740 does have a tangible increase. And he, this growth, is about twice. 15,000 pages is about two months of active reading, and such a long autonomy is indeed a record among all readers of any manufacturers on our market.

Here, perhaps, I’ll add that in some “disciplines” the readers showed themselves exactly the same. For example, in opening games (1 second in both cases), in opening photos (1-2 seconds depending on the weight of the file), in leaving sleep mode (1 second), and so on. In a post I described only those situations where the difference in performance between PocketBook 626 Plus and PocketBook 740 is very clearly visible.

Well, we can say that the developers even downplayed their achievements. In most tests, this is not about 40%, but at least a twofold increase in speed in the case of PocketBook 740. Probably, PocketBook decided to play it safe: in some cases, which I did not fix, the new reader can really be only 40% faster than the old one. And so they indicated precisely this figure, so to speak, being modest.

In general, the new dual-core platform definitely benefitted from the PocketBook 740. The reader is pleasant to use, there are no micro-delays (fractions of a second) that happen with the same PocketBook 626 Plus in the new model. In terms of speed, it can be compared ... say, with smartphones of the previous generation - the year of commercials 2016. For a reader, this is a very compliment.

Let me remind you that PocketBook 740 costs 14,900 rubles. This is currently a unique offer in the e-book market. Firstly, because for that kind of money you simply won’t buy another reader with similar characteristics. Secondly, because any other reader with a large (8 ") screen will be at least 3,000 rubles more expensive, and in terms of a set of modern functions and screen quality it will be inferior to the novelty from PocketBook. Finally, I note that this is the first PocketBook model, Russian the version of which is cheaper than the European version. The

list of key features of the PocketBook 740 is as follows:

- a completely new design;

- a new concept of a "small large" reader;

- a dual-core processor and a radical increase in speed;

- A 7.8-inch screen with a very high resolution, and at the moment this is the best E Ink display that I personally have seen;

- Cloud service PocketBook Cloud;

- two times longer autonomy than any other reader of any manufacturer - up to two months;

- color temperature adjustment (second pocketbook with this option after PocketBook 631 Plus );

- A guarantee for 2 years or even 3 years, if you buy directly on the manufacturer’s website - pocketbook.ru.

I am pleased to listen to constructive criticism and answer questions in the comments.

*We arm ourselves with a stopwatch - and go!*It is worth noting that at the very end of February, a firmware update was released for the PocketBook 740. It focuses specifically on improving productivity. That is, if earlier it was just fast, now we are promised another tangible increase in the speed of work. Of course, I immediately installed this update and tested it with the latest firmware version.

**Test number of times.**I started testing PocketBook 740 since the firmware update. An update weighing 220 MB was installed in about 2 minutes. For comparison: when I bought PocketBook 626 Plus in November 2017 and turned it on for the first time, the reader also offered to upgrade; the firmware weighed about 200 MB, and it took about 10 minutes to install it. It is clear that in these firmware there could be completely different corrections, and their type in theory could affect the installation speed. Nevertheless, the fivefold difference (2 minutes at 740 versus 10 minutes at 626 Plus) hints that the 740th reader is noticeably faster.**Test number two.**Next, I decided to open a large PDF file on both readers. I chose the book Half-Life 2: Raising the Bar in the Russian translation. But for starters, I downloaded this book to the PocketBook 740 and PocketBook 626 Plus via USB using one port on the laptop’s body and the same cord. The results are as follows: PocketBook 626 Plus produced a speed of 1.7 Mb / s, and PocketBook 740 - 18.7 Mb / s. That is, the new reader here was about ten times faster than the old one. (Hereinafter: I conducted each test three times and took the average value - I consider it incorrect to write the best numbers.)**Test number three.**Actually opening the Half-Life 2: Raising the Bar file in a PDF of 107 MB. PocketBook 740 showed the first page of the book in 3 seconds, and PocketBook 626 Plus - in 8 seconds. Thus, the new product is about three times faster when opening “heavy” PDFs. Plus they scroll through on the PocketBook 740 significantly smoother, without jerking.**Test number four.**I suspect that not everyone will open huge PDFs on the reader, most users will restrict themselves to books of other formats - the same FB2, for example. Therefore, I alternately opened on readers the complete works of Sherlock Holmes in FB2.ZIP with a volume of 1.5 MB. The difference was less impressive: PocketBook 740 did it in 2 seconds, PocketBook 626 Plus - in 4. That is, the first model is twice as fast. Which, however, is also very tangible.**Test number five.**Next, I tested the speed of inclusion of readers with the opening of the book - all the same Sherlock Holmes. PocketBook 740 loads and displays text in 6 seconds, while PocketBook 626 Plus spends 13 seconds on this operation. The difference is more than twofold.**Text number six.**For the sake of order, I decided to test the browser by opening Geektimes.ru in it. I note that the speed in this case depends not only on the Wi-Fi connection, but also on software and hardware, too. For example, here’s a test of iPhone SE and iPhone 7 , where they open the same websiteat

completely different speeds.

Pocketbooks also performed different tasks: PocketBook 740 loaded Geektimes.ru main page in 6 seconds, PocketBook 626 Plus - in 11.

**Bonus Track: Battery Test.**This test is in no way connected with performance, it concerns battery life. PocketBook says that thanks to various kinds of software and hardware optimizations, the new flagship PocketBook 740 allows you to turn over 15,000 pages on a single charge, while the 6-inch models of the previous generation, the same PocketBook 626 Plus, only 8,000. Perform a test with 15 or 8 Thousands of page turning is unrealistic, so I read 300 pages on one model and 300 pages on another, setting the fonts so that the same amount of text fits on one page, and setting the backlight brightness to the same level.PocketBook 626 Plus consumed 5% of the battery while reading the indicated amount of text, while PocketBook 740 consumed only 2%. A simple calculation shows that in the case of the old PocketBook 626 Plus, a full battery charge would theoretically be enough for 6,000 pages, and in the case of the flagship PocketBook 740 - for those same 15,000. It is clear that all this is very arbitrary, and in the first case it may well turn out , for example, 7,000, and in the second - 13,000. Or 5,000 and 16,000.

In a post I described only those situations where the difference in performance between PocketBook 626 Plus and PocketBook 740 is very clearly visible.

**As a conclusion**Well, we can say that the developers even downplayed their achievements. In most tests, this is not about 40%, but at least a twofold increase in speed in the case of PocketBook 740. Probably, PocketBook decided to play it safe: in some cases, which I did not fix, the new reader can really be only 40% faster than the old one.
