Domestic A8 rk2918 and Samsung s5pv210 who are more powerful ?!

 

With the recent exposure of rk2918 products, many manufacturers have made rk2918 with capacitive screens. The new rk2918 products seem quite attractive. And this A8 kernel master with a clock speed of up to 1.2g, Will its performance shake s5pv210, which is known as the "strongest A8?

As a new product, rk2918 is more attractive than s5pv210 with a capacitive screen with a higher resolution. Isn't it? However, the performance of the two is also a concern of many board friends. Considering the recent rk2918 consultation questions from many board friends, we can predict the performance of both of them here for your reference only. You are welcome to discuss this.

Rk2918 and s5pv210 are the same as the A8 kernel. Although the clock speed is different, both of them have K Level-2 caches. It is easy to compare the processor performance. The pure clock speed can be distinguished. This time, you don't have to worry that the rk2918 will shrink in the clock speed. It has been confirmed that the rk2918 frequency is 1.2 GB, unless the manufacturer intends to lower the frequency of the officially listed rk2918 product in exchange for better power consumption control.

Because the rk2918 process is 55nm, and s5pv210 is 45nm, The rk2918 with a higher clock speed is larger than s5pv210 in terms of power consumption fever. However, rk2918 uses ddr3 memory, and s5pv210 is DDR2 memory. drr3 provides more bandwidth and lower power consumption than DDR2. Therefore, rk2918 is not full-body, and is a power-consuming user.

As for the increase in ddr3 memory compared with DDR2, although ddr3 bandwidth is more adequate theoretically, more bandwidth can improve performance for memory usage as the core of cache display, however, based on the current data, it cannot be determined whether the rk2918 memory is a single-channel or dual-channel design. It can be determined that the s5pv210 memory is a dual-channel design. If both are dual channels, rk2918 ddr3 not only reduces power consumption, but also has an advantage in memory performance.

The final result of rk2918 and s5pv210 is largely determined by the display core of the two. S5pv210 is called the "strongest A8" because s5pv210 has this powervr SGX 540, and rk2918 has not published its core details, the rumored message is gc800 (60 m tri/s ). However, according to the latest information, the core of rk2918 does not reach 60 m tri/s announced in January, which is currently known as 40
M tri/s (it is possible that the core frequency is reduced to balance power consumption ). The core performance of rk2918 is about powervr SGX 540.70%However, these references only come from the prototype data. The rk2918 products that are listed on the market may have better performance. According to the release of the rk2918 capacitive screen products by major manufacturers, the manufacturers have full confidence in rk2918.

Although the 3D performance of rk2918 cannot match s5pv210, the gap is not small. However, you must note that,In fact, s5pv210 has a poor game performance!I believe that all users who have played M7 can realize that as long as they can run normally, the game is completely crushed. Therefore, even if the 3D performance of rk2918 is less than s5pv210, and with the powervr SGX 540 standard, you do not need to worry about the problem of playing the rk2918 game, you need to worry about whether these games are perfectly compatible.

Compared with s5pv210, rk2918 still has a major advantage, that is, video decoding issues that most people are concerned about. Currently, rk2918 supports almost all P decoding, especially rmvb. Of course, we do not have a real machine test. It is not clear whether P is a perfect support, but it seems that P will not be a problem.

Finally, let's make a summary.Rk2918 processor performance is slightly better than s5pv210, Higher frequency, may be a little better in Flash online videos and flash online games;Rk2918 memory performance may be slightly higher or lower than s5pv210, but ddr3 does reduce some power consumption,How much makes up for the power consumption problem caused by some 55nm processes;The 3D performance of rk2918 is worse than s5pv210.But for players, it is enough to deal with the current mainstream tablet games;Rk2918 video decoding is more comprehensive than s5pv210For those who like HD movies, it is a good choice. Finally, ban youhui predictsRk2918 (8-inch) and s5pv210 (8-inch) should have a similar endurance time, there will be no significant difference, and the rk2918 may be a little hot.Compared with some s5pv210 tablet products, rk2918 tablet products have advantages in the system version, Android
2.3 is a little more attractive than Android 2.2.

Considering that machines run more smoothly in the Android 2.3 system environment than in the Android 2.2 system environment, their performance is not absolute,Ban youhui discussed the situation here based on rk2918 (8-inch 1024x768 resolution Android 2.3, which is the latest mainstream 8-inch product configuration) compared with s5pv210 (7-inch 800x480 resolution Android 2.2 recently, you are concerned about various M7 ).Therefore, the differences between system versions and resolutions can offset some gaps.

I have made a lot of comments. The next preliminary prediction conclusion is for reference only. Rk2918 configuration is more balanced than s5pv210. Although the 3D performance gap is obvious, rk2918 is indeed more worthy of choice than s5pv210 from the perspective of "enough, if you are a game guru, "the strongest A8" is still your best choice. Of course, you have to consider the current tablet game compatibility issues! If you are more concerned about video decoding or a more comprehensive experience, rk2918 can meet your basic needs. At last, I would like to remind you that you should not use your tablet as a computer. Whether it is rk2918 or s5pv210, you will be unable to cope with a large amount of flash! Therefore, do not look too high when purchasing low-end tablets!
