The first thing you need to pay attention to is the type of processor. The processor is the main thing when choosing, and the amount of RAM is already secondary and visits from your requirements. When buying a GU with a normal processor, you are practically guaranteed to get high -quality components (display, bluetooth, etc.) and functionality.
Below I have listed the most common processors and relevant for today.
All GU use various processors, and those, in turn, have their own MCU platform (microcontroller version) - this is essentially the name of the manufacturer (you can find in the settings - about the device). Before the order, ask the seller a screenshot of the Mcu version. If you did not find (did not receive from the seller) this information before the purchase - consider that you bought a cat in a bag. You can buy a gu with a quick processor, but get a wretched platform, and the whole "steepness" of a quick toal cat under the tail.
Note that the firmware of different topics are not suitable for each other.
Processor: Spreadtrum UIS7862 (Unisoc UMS512) Android: 10.0, CPU: 8 cores (octa cores) 2 core ARM cortex A75 + 6 nuclei ARM cortex A55
RAM (RAM): LPDDR4 3/4/6/8 GB, Rom (internal memory): 32/64/128, 256
A new solution from Spreadtrum (heir to the Spreadtrum SC9853 processors). The fastest according to the tests in Antutu. The newest and most relevant for today. There is no overheating problem. A bunch of modified firmware. It has a built-in SIM-cards for the Internet, 4G LTE support. He knows how to make calls through a SIM card and send/accept a text SMS message. Supports the work of 4 cameras at the same time (
Circular Review System 360 - Extra Option), AHD cameras and WiFi 5 GHz. In my opinion, a very worthy option.

s Inside, the GU with the UIS7862 processor is absolutely identical! I repeat - do not overpay!
The processor is represented by three platforms (ruler, manufacturers):
Fyt platform (Fangyitong)Recommendations when choosing a gua on this platform>>>-
General topic on the forum (Mcu Fyt>>>)Hundreds of Nunemi of the gu and "eminent brands" on Aliexpress produce gua on this platform. There are essentially any differences between them. Where it is cheaper to take there (adjusted for a normal description of the lot from the seller and specialization of the store). The only important (very desirable) condition is the presence of cooler coil coil.

Teyes SPRO + / CC2 + / CC3 and Kingbeats K2 +Commercial project of businessmen from the Russian Federation, promoted brand. Fyt platform, but with its "Dopilin" software.
-
Winca (Farcar S400) Fyt53.Also a separate manufacturer "with his software". Nothing interesting.
Topway platform (TS10)Serious manufacturer. Almost closed software. Regular updates of the firmware and software by air. There is a paid mod. Redmod firmware. As a rule, cheaper than gua on the FYT platform. The functionality is more interesting than that of FYT, but it is difficult to correct the firmware on your own.

Topic on the forum (MCU TS10) Conditional name a007New platform. That's all. A wretched and incomprehensible creature. See all answers in the topic. That says it all.

The younger brother of the processors UIS7862.
Great solution in conjunction speed - price - quality.
Facecesally, it is no different from UIS7862. Of the differences compared to UIS7862, I noticed: the absence of an optical and coaxial output, the absence of RDS, the younger DSP AKM processor 38, the Toshiba amplifier, one internal bluetooth module (depending on the manufacturer, saw models with two), which can only connect the phone as a headset as a headset and OBD2 adapters. For comparison, UIS7862 has two bluetons of the module, the second (external) can connect the additional devices (though through "g" and not all)))

Very nimble percent (second after UIS7862). Has HDMI video output. If you choose this Rockchip processor (PX6, PX5, PX30), I recommend taking MCU MTC/E/P_XXX at the Platoform since the GU on this platform is driven by users along and down, they have a bunch of firmware, including modified (with rut, flexible rights settings full of Russian translation, and a bunch of utility).

The younger "brother" PX6. Once was nimble and popular. The percent is already rather weak, I can’t recommend it anymore.

Built -in DSP module. Support for SIM maps and circular review systems 360. In my personal opinion, a very good option, but there is no firmware mod on this processor. Therefore, it is worth considering only if a pyremer for your car model is only a GU with such a processor, or it is some unique gu (a tapser is stylized under ShSU, has physical buttons, etc.).

Or 8.1) and type with DSP. A cheap option in the price range is $ 50-150, for this money you can only take a gu at this pro. With certain refinements and drifts, you can use it (I recommend immediately ordering the amplifier chip and a radio module for replacement).
