Comparison Apple Watch 7 Aluminum 45 mm vs Apple Watch 6 Aluminum 44 mm

The size of the display installed in the gadget; for round screens, respectively, the diameter is indicated.

A larger screen, on the one hand, is more convenient to use, on the other hand, it significantly affects the dimensions of the entire device, which is especially critical for wearable gadgets. Therefore, manufacturers choose the display size in accordance with the purpose and functionality of each specific model — so that there is enough space on the screen and the device itself is not too bulky.

It is also worth mentioning that screens with a similar size may have different aspect ratios. For example, traditional smartwatches are usually equipped with square or round panels, while in fitness trackers, screens are often made elongated in height.

Screen size in dots (pixels) horizontally and vertically. In general, this is one of the indicators that determine the image quality: the higher the resolution, the clearer and smoother the picture on the screen (with the same size), the less noticeable are the individual dots. On the other hand, an increase in the number of pixels affects the cost of displays, their power consumption and requirements for a hardware platform (more powerful hardware is required, which itself will cost more). In addition, the specifics of using smartwatches is such that there is simply no need to install high-resolution screens in them. Therefore, modern wrist accessories use displays with a relatively low resolution: for example, 320x320 with a size of about 1.6" is considered quite sufficient even for premium watches.

The density of dots on the screen of the gadget, namely, the number of pixels that are on each inch of the panel vertically or horizontally.

The higher the PPI, the higher the detail of the screen, the clearer and smoother the image is. On the other hand, this indicator affects the price accordingly. Therefore, the higher the density of points, the more advanced, usually, this gadget is in terms of general capabilities. However, when choosing a screen, manufacturers take into account the general purpose and functionality of the device; so that even a small number of PPIs usually does not interfere with comfortable use.

The model name of the processor (CPU) installed in the watch. Knowing this name, you can find detailed data on a particular CPU and evaluate its level and general capabilities. This is especially important due of the fact that these capabilities depend not only on the basic specs (number of cores, clock frequency), but also on specific design nuances.

The number of cores in the gadget's processor.

The core is the part of the processor responsible for processing a single stream of instructions. Accordingly, multiple cores allow you to handle multiple threads at the same time, which makes the processor multitasking and improves its performance. However, note that the presence of 2 or even 4 cores does not guarantee high computing power even for CPU itself — it often happens that an advanced dual-core chip works faster than an inexpensive quad-core one. In addition, the actual performance and speed of the system depends on many other specs that are not related to the processor. Therefore, the number of cores is solely for reference and marketing information, in itself it cannot be a basis for evaluating a gadget and comparing it with other models.

The amount of random access memory (RAM) installed in the gadget.

This parameter is one of the key ones for the overall performance of the system: the more RAM, the faster the device works, the easier it is to handle tasks with high hardware requirements and the wider the set of applications that the gadget is able to run. Note that a large amount of RAM can compensate for even a relatively weak CPU. At the same time, you need to remember that different operating systems (see above) have different requirements for RAM and features of its use; therefore, only models on the same software platform can be compared by this indicator.

Body colours in which the gadget is available. Note that in this case "stainless steel" is only the name of the shade, the body material itself may be different (for example, aluminium).

The colour of the strap that the gadget comes with. If several options are indicated in this paragraph, this, usually, means that the user can pick the colour of his choice. Other options may be envisaged — for example, the presence of several straps in the kit, or the possibility of such a set at the request of the user — but they are much less common.

— Skin. Leather straps are typical for a business style, they look rich and respectable, however, they are quite expensive. On the practical side, this material is strong, reliable and resistant to moisture; at the same time, it is quite demanding to care for, and if the appropriate rules are not followed, cracks may appear on the strap.

— Rubber/silicone. Quite a popular material used not only for fitness trackers, but also for traditional watches. Rubber straps do not look as rich as leather ones, but they are also quite decent, while they are strong enough, durable, resistant to moisture and pleasantly felt on the hand. Silicone is similar in properties, which in appearance is practically indistinguishable from rubber. But the silicone is softer, does not pinch the hand and is more pleasant to the touch.

— Metal. Metal straps (bracelets) are mainly made of stainless steel, but there are other options. Anyway, bracelets are highly durable and can be both light and massive, depending on the composition of the metal. It is also worth mentioning the high thermal conductivity of this material. Such a bracelet pleasantly cools the hand in the warm season, but causes the opposite effect in the cold.

— Milanese bracelet. Metal bracelets made of links of very fine weaving (about 1 mm in size, or even less). The m...aterial of such a bracelet may be different; most often it is steel, but more expensive metals are also found. Anyway, such a bracelet has an original appearance, and also provides good air access, allowing the skin to breathe. Among the shortcomings of Milanese bracelet, it can be noted that the links can “bite” the hair on the arm, creating discomfort.

— Textile. Usually, strong dense fabric (like nylon-based CORDURA) is used for straps, resistant to moisture, ultraviolet and other adverse factors. For some users, this material is more pleasant than other options; however, for a number of technical reasons, fabric straps were not widely used.

Many models of wearable gadgets are available with several strap options to choose from.
