Comparison Asus TUF Gaming FX505DT [FX505DT-BQ138] vs HP Pavilion Gaming 15-ec0000 [15-EC0013UR 8NF73EA]

The maximum brightness that a laptop screen can provide.

The brighter the ambient light, the brighter the laptop screen should be, otherwise the image on it may be difficult to read. And vice versa: in dim ambient light, high brightness is unnecessary — it greatly burdens the eyes (however, in this case, modern laptops provide brightness control). Thus, the higher this indicator, the more versatile the screen is, the wider the range of conditions in which it can be effectively used. The downside of these benefits is an increase in price and energy consumption.

As for specific values, many modern laptops have a brightness of 250 – 300 cd / m2 and even lower. This is quite enough for working under artificial lighting of medium intensity, but in bright natural light, visibility may already be a problem. For use in sunny weather (especially outdoors), it is desirable to have a brightness margin of at least 300 – 350 cd / m2. And in the most advanced models, this parameter can be 350 – 400 cd / m2 and even more.

The contrast of the screen installed in the laptop.

Contrast is the largest difference in brightness between the lightest white and darkest black that can be achieved on a single screen. It is written as a fraction, for example, 560:1; while the larger the first number, the higher the contrast, the more advanced the screen is and the better the image quality can be achieved on it. This is especially noticeable with large differences in brightness within a single frame: with low contrast, individual details located in the darkest or brightest parts of the picture may be lost, increasing the contrast allows you to eliminate this phenomenon to a certain extent. The flip side of these benefits is an increase in cost.

Separately, we emphasize that in this case only static contrast is indicated — the difference provided within one frame in normal operation, at constant brightness and without the use of special technologies. For advertising purposes, some manufacturers may also provide data on the so-called dynamic contrast — it can be measured in very impressive numbers (seven-digit or more). However, you should focus primarily on static contrast — this is the basic characteristic of any display.

As for specific values, even in the most advanced screens, this indicator does not exceed 2000: 1. But in general, modern laptops have a rather low contrast ratio — it is assumed that for tasks that require more advanced image characteristics, it is more...reasonable to use an external screen (monitor or TV).

The colour gamut of the laptop matrix according to the Rec.709 colour model or according to sRGB.

Colour gamut describes the range of colours that can be displayed on the screen. It is indicated as a percentage, but not relative to the entire variety of visible colours, but relative to the conditional colour space (colour model). This is due to the fact that no modern screen is able to display all the colours visible to humans. However, the larger the colour gamut, the wider the screen's capabilities, the better its colour reproduction.

Specifically, sRGB and Rec.709 are the most popular of today's colour models; they have the same range and differ only in the scope (sRGB is used in computers, Rec. 709 is used in HDTV). Therefore, the closer the colour gamut is to 100%, the more accurately the colours on the screen will match the colours that were originally intended by the creator of the film, game, etc. At the same time, note that such accuracy is not particularly needed in everyday use — it critical only for professional work with colour; and even in such cases, it is more convenient to buy a separate monitor with a wide colour gamut for a laptop, rather than looking for a laptop with a high-quality (and, accordingly, expensive) matrix.

The colour gamut of the laptop matrix according to the Adobe RGB colour model.

Colour gamut describes the range of colours that can be displayed on the screen. It is indicated as a percentage, but not relative to the entire variety of visible colours, but relative to the conditional colour space (colour model). This is due to the fact that no modern screen is able to display all the colours visible to humans. However, the larger the colour gamut, the wider the screen's capabilities, the better its colour reproduction.

The Adobe RGB colour model was originally developed for print applications; the range of colours covered by it corresponds to the capabilities of professional printing equipment. Therefore, theoretically, the extensive coverage of this model will be useful to those involved in the design and layout of high-end printed products. However most laptop screens have very limited Adobe RGB values, rarely exceeding 74%; however, you can also find high-end models where this figure approaches 100%. Of course, the cost of such laptops will also be appropriate; therefore, it makes sense to pay attention to them, first of all, when the ability to work with colour “on the go” is of key importance. If this is to be done in one place, it may be more justified to buy a separate monitor with a wide colour gamut (especially since a monitor with such characteristics is easier to find than a laptop).

The result shown by the laptop processor in the Passmark CPU Mark test.

Passmark CPU Mark is a comprehensive test that is more detailed and reliable than the popular 3DMark06 (see above). It checks not only the gaming capabilities of the CPU, but also its performance in other modes, based on which it displays the overall score; this score can be used to fairly reliably evaluate the processor as a whole (the more points, the higher the performance).

The result shown by the laptop's graphics card in 3DMark06.

This test primarily determines how well a graphics card handles intensive workloads, in particular, with detailed 3D graphics. The test result is indicated in points; the more points, the higher the performance of the video adapter. Good 3DMark06 scores are especially important for gaming laptops and advanced workstations. However, it is difficult to call them reliable, since measurements are made on video cards with different TDPs and an overall average score is given. Thus, your laptop can have either more or less than the specified result - it all depends on the TDP of the installed video card.

The result shown by the laptop graphics card in the 3DMark Vantage P test.

Vantage P is a variant of the popular 3DMark test — namely, the next version of this test after 3DMark06 (see above). Like all such tests, it is designed to test the performance of graphics under high loads and displays the results in points; the more points, the more powerful and performant the graphics card is. Good results in 3DMark Vantage P are especially important if the laptop is going to be used for demanding games. However, it is difficult to call them reliable, since measurements are made on video cards with different TDPs and an overall average score is given. Thus, your laptop can have either more or less than the specified result - it all depends on the TDP of the installed video card.

A device for working with removable memory cards. Usually, it looks like a characteristic slot right on the laptop case, into which the media is inserted. There are different standards for memory cards, a list of compatible standards is indicated in the note to this item. It is worth noting here that for modern laptops it is almost mandatory to support the SD format and its modifications — SD HC, often also SD XC; other options may also be envisaged, but they have not received such distribution. Anyway, this feature is convenient because memory cards are widely used in other types of electronics: for example, SD is the generally accepted standard in digital cameras, and microSD (compatible with SD slots through simple adapters) is used in smartphones. Accordingly, the presence of a card reader greatly facilitates the exchange of data between a laptop and external devices.

Number of USB 3.2 gen1 ports provided in the laptop. Initially, this interface was called USB 3.0, later USB 3.1 gen1.

Be that as it may, USB is the most popular modern interface for connecting various peripherals to computer - from keyboards, mice and flash drives to very original devices. It can also be used to charge smartphones and other gadgets. And USB 3.2 gen1 is the successor to the popular USB 2.0. In this version, the data transfer speed was increased 10 times - up to 4.8 Gbit/s, and the power supply for external devices was also increased. At the same time, devices with other versions of USB can be connected to the USB 3.2 gen1 port - the main thing is that they have full-size USB A plugs and have enough power for normal operation.

As for the number of USB connectors, the more there are, the more peripherals you can connect to the laptop without using splitters.
