“Ten Years of Tribute” extra-large carton (media edition, non-retail packaging). From this detail, we can see that Redmi has become the orthodox inheritor of Xiaomi mobile phones that insisted on the ultimate cost-effectiveness.

The first generation of Xiaomi mobile phones-“The undead Android is a good toy Xiaomi mobile phone review ”

Xiaomi has specially reserved and bound the ” Evaluation of a Good Toy Xiaomi Mobile Phone ” written by us nine years ago. Looking at the work written by Teacher Yonghui back then, it is still in the era of Android 2.3, with a simple and original interface, which has a sense of age.

Redmi K30 Extreme Edition Design & Appearance

The Redmi K30 Extreme Commemorative Edition is still a rare 5G flagship with a true full screen.

The quality of this screen is quite good, a 6.67-inch pop-up full screen, a resolution of 2400 x 1080 FHD+, a peak brightness of 1200 nit, and a contrast ratio of 5000000:1. The regret of the high screen refresh that was left on the Redmi K30 Pro series has been made up-upgrade the 120Hz refresh rate + 240Hz touch sampling rate.

The breathing light was originally a standard configuration of mobile phones, but the structure of flagship phones has become more and more complicated, and various manufacturers have canceled it by default. The Redmi K30 Extreme Commemorative Edition follows the pop-up + breathing light design of the K20 series. Different notification scenes display different color lighting effects, such as charging blue lighting effects and incoming green lighting effects to achieve a multi-dimensional reminder effect.

The Redmi K30 Extreme Commemorative Edition is available in three colors: Muyue White, Extreme Night Black, and Mint Green. What we got is Mu Yue White. At the bottom are the USB-C interface and SIM card slot.

It should be noted that, unlike the Redmi K30 Pro, the Redmi K30 Extreme Commemorative Edition eliminates the 3.5 mm headphone jack, but retains the infrared remote control and NFC.

Redmi K30 Extreme Edition Performance

Many people are chanting “MTK YES” this year, and MediaTek has indeed handed over a very eye-catching report card: Previously, the latest Digitimes research report showed that in the second quarter of this year, China’s smartphone AP (application processing) market, MediaTek ranked first with 38.3%, surpassing Qualcomm’s 37.8%. In the not-too-short days, the proportion of MediaTek in domestic mobile phones is believed to be higher and higher.

However, from commercially available models, the main force of Fage may be more focused on the high-end MediaTek Dimensity 800 series. The flagship Dimensity 1000+ was previously equipped with only one model. Now the Redmi K30 Supreme Commemoration The addition of the version is undoubtedly another boost.

7nm process technology

In 2019 and even now in 2020, most of the flagship and sub-flagship SoCs use the 7nm process. However, when we delve into the processes of various SoCs, we will find that there seem to be some differences in the 7nm of different products.

For example, TSMC’s N7 (N7FF) is applied to Snapdragon 855, Kirin 990, and Apple A12; TSMC’s N7P is applied to Snapdragon 865, Apple A13, and Dimensity 1000L; TSMC’s N7+ is applied to Kirin 990 5G; Samsung’s 7LPP is applied to Exynos 9825, Snapdragon 765G.

Among them, TSMC began mass production of the 7nm process in 2018. The N7 (or N7FF) just mentioned is the first batch of TSMC 7nm solutions, and DUV is the first generation solution. In 2019, TSMC launched the N7P, which is the second-generation 7nm, which is an improved version of the first-generation N7 solution. It still uses DUV and the same design guidelines.

N7+ is different from N7P. It starts to use EUV extreme ultraviolet lithography. According to TSMC, the overall performance will be better than N7. It is currently unclear which solution was adopted for the Dimensity 1000+ 7nm process. From the perspective of the Dimensity 1000L using TSMC’s N7P, the Dimensity 1000+ must be the same.


Dimensity 1000+ directly integrates four Cortex-A77 large cores and four Cortex-A55 small cores, with frequencies of 2.6GHz and 2.0GHz respectively. The performance of A77 is 20% higher than that of A76. A76 is a very successful core architecture launched by ARM. The combination with the 7nm TSMC process brings a huge performance and efficiency leap, such as the Snapdragon 855.

Cortex-A77 is the direct successor of A76. The new core is largely consistent with the previous generation products. While maintaining the excellent energy efficiency of the A76 architecture and a smaller core area, it further improves performance. The A77 architecture still uses the ARMv8.2 CPU core and is intended to be paired with the Cortex-A55 small core. Besides, compared with the A76, the basic configuration of the A77 has not changed. You can still see the 64KB L1 instruction and L1 cache, and the 256 or 512KB L2 cache.

In general, the improvement of A77 over A76 is not as large as that of A76 over A75. It is still a continuation of high-performance and energy-efficient products (which regarded as an improved version of A76).

For the identity of the evaluation machine, GeekBench has been blocked from the Internet access, so here we will refer to the performance level of Dimensity 1000+ CPU from the running score data collected by Fast Technology in the past.

According to the measurement standard of Geekbench 5, the performance of Dimensity 1000+ single-core is between Snapdragon 765G and Snapdragon 865, 23% more than Snapdragon 765G and only 14% lower than Snapdragon 865. In terms of multi-core, there is a clear distinction between mid-range cores and flagship cores. Snapdragon 765G falls behind Dimensity 1000+ with a gap of 33%, while Dimensity 1000+ and Snapdragon 865 are only 12% behind.

In other words, according to the evaluation system of Geekbench 5, whether it is a single score that reflects absolute performance or a multi-core test that tests scheduling coordination, Dimensity 1000+ is the same as the Snapdragon 865 and belongs to the flagship camp. The mid-to-high-end Snapdragon 765G has opened a huge gap.

If we can remove the blocking of network permissions in the future, we will test the performance of Geekbench 5 of the Redmi K30 Extreme Commemorative Edition.


On the GPU side, Dimensity 1000+ integrates nine Mali-G77 cores, which improves performance by up to 40% compared to G76, and supports 90-frame chicken games and 120-frame racing games. Mali-G77 GPU adopts a new architecture Valhall. According to ARM’s official statement, Mali-G77 has a 30% increase in performance, a 30% increase in performance, and a 60% increase in machine learning performance over the previous generation.

Under the same process and the same performance, G77 continues to achieve 30% year-on-year energy efficiency improvement, and saves 50% power consumption compared with Mali-G72, which means that the final performance of Mali-G77 is close to the GPU performance of Apple A12, surpassing Qualcomm Adreno 640. In the current first echelon of mobile GPU.

For the same reason, GFXBench has also been blocked from network access and cannot run, so here we will refer to the performance level of Dimensity 1000+ GPU based on the benchmark data collected by Kuaidi Technology in the past.

Among the above test sub-items, the best performance of GPU graphics computing power is Manhattan (Manhattan), Tyrannosaurus (T-Rex), and Aztec ruins test scenes. The Tyrannosaurus rex test is biased towards GPU texture and fills rate throughput, and Manhattan is the core heavy task of the shader.

From the histogram compiled by Fast Technology, it is not difficult to find that the performance of Dimensity 1000+ GPU is tightly biting the Snapdragon 865, which is known for its graphics capabilities. The smallest gap between the two is only 5% and at most only 12%.

In terms of GFXBench’s overall GPU graphics computing performance test results, Dimensity 1000+ is extremely close to the Snapdragon 865 (a slight gap of 5% to 12%).

AnTuTu running scores

The same reason for the confidentiality of the evaluation machine information is still the same. AnTuTu has been disabled from Internet access to the running score software. Therefore, the running scores here are only for initial reference. The final score is recommended to be based on the results after the listing.

According to AnTuTu’s evaluation system, the performance level of the Redmi K30 Extreme Commemorative Edition is roughly between the Snapdragon 865 and Snapdragon 855 models.

Androbench test

About Androbench: AndroBench is a benchmark application that can measure the 4K random storage and storage performance of Android devices, including internal or external storage. Typical dual-channel UFS 2.1 flash memory speed

4. “Fage” exclusive gameplay: 5G+5G dual card dual standby

MediaTek Dimensity 1000+ is a 5G single chip that supports dual-carrier aggregation, which can aggregate two 100MHz carriers to obtain 200MHz bandwidth. It is worth mentioning that China Unicom and China Telecom have already jointly built and shared the 3.5GHz 200MHz 5G frequency band across the country, that is, 3400MHz-3600MHz. Dimensity 1000+ dual-carrier aggregation technology can just be used.

It supports NSA/SA dual-mode, TDD/FDD dual-standard, naturally, it also supports 5G+5G dual card dual standby, and supports any combination of NSA+SA, SA+SA, and can experience different 5G networks at the same time, of course, t also supports 4G+5G dual card dual standby.

Thanks to Dimensity 1000+’s 5G+5G dual-SIM dual-standby feature blessing, Redmi K30 Extreme Commemorative Edition has become a 5G mobile phone that supports 5G+5G dual-sim dual-standby, which is different from Redmi K30 and Redmi One big difference between K30 Pro and other models.

That is to say, in the 5G network environment, whether it is China Mobile, China Unicom, or telecommunications users, they can receive 5G signals from different operators at the same time, realize dual-card 5G standby, and switch to better 5G networks at any time.

At the same time, the Redmi K30 Extreme Commemorative Edition also adds support for more 5G frequency bands such as n79 based on the regular 5G frequency band, to achieve full support for n1/n3/n41/n78/n79 (n1, n3 need to be released by the operator through software Upgrade support).

However, the 5G network construction of the three major operators is still steadily advancing. When the actual network speed is measured, because the network stability of different regions, different times, and different operators may be different, the results of the network speed measurement may be somewhat different from what you experience.


Batteries have always been an important aspect of Redmi’s uncompromising even during the Redmi era, and large batteries have almost become a brand label.

Compared with the Redmi K30 Pro, the battery of the Redmi K30 Extreme Commemorative Edition has little change. It is equipped with a 4500 mAh battery, which is slightly smaller than the 4700 mAh K30 Pro, but there is no obvious impact on battery life.

The Redmi K30 Extreme Commemorative Edition is also equipped with a relatively fast 33W wired fast charge at the same price based on a large battery. Next, let us test the endurance and charging performance of the Redmi K30 Extreme Commemorative Edition through actual measurements.

The picture quality and frame rate of “Peace Elite” are all set to the highest level it can achieve, and the average discharge current is monitored to be about 740mA. From this, it can be estimated that the Redmi K30 Extreme Edition is at HDR HD + ultra-high frame rate. Under the circumstances, the game life of “Peace Elite” may reach 6 hours.

Under the condition of 70% brightness and 30% volume, connect to Wi-Fi to play 1080P online video. We have monitored that the average discharge current is about 405mA. From this, it can be estimated that the continuous video playback life in this environment can almost reach 11 About hours.

The Redmi K30 Extreme Commemorative Edition is equipped with a 33W charge pump fast charge, which is faster than the 30W of the Xiaomi 10 in terms of paper parameters. It can recover blood from 15% to 95% in 50 minutes when the screen is turned on.


Let’s review the previous Redmi K30 Pro: 64MP Sony IMX686 + 13MP ultra-wide-angle lens (123°) + 5MP telephoto macro lens (AF 3-10cm) + 2MP depth-of-field lens (1.75μm).

This time, the Redmi K30 Extreme Commemorative Edition is adjusted based on Redmi K30 Pro. When we got the Redmi K30 Extreme Commemorative Edition, the official did not mention the specific model of each image sensor, so we obtained the specific model of the camera image sensor of our review machine through debugging:

Sony IMX682 64 Megapixel main camera + SK Hynix hi1337 13 Megapixels ultra-wide-angle lens + Samsung S5K5E9 5 million pixel telephoto macro lens + OV02B 2 Megapixel portrait depth of field lens. Redmi K30 Extreme Commemorative Edition bug report shows the camera module model.

That is to say, according to the situation of the evaluation machine in our hands, compared with the Redmi K30 Pro, the Redmi K30 Extreme Commemorative Edition has the main camera adjusted from Sony IMX686 to IMX682 (the difference between the two is not big), and the ultra-wide-angle has changed from 123° There is almost no change beyond 119°.

However, it should be noted that the Redmi K30 Extreme Edition on the MediaTek platform has a different imaging color style than the Redmi K30 Pro on the higher communication platform, and the imaging color is relatively richer.

Redmi K30 Extreme Edition Verdict

We are not unfamiliar with the specifications of the Redmi K30 Extreme Edition. Many configurations have been seen on the K30 Pro. The changes are nothing more than customizing Samsung’s 120Hz AMOLED screen, discarding the 3.5mm headphone jack in exchange for dual speakers, and adjusting the SoC to Dimensity 1000. +, the main camera lens is adjusted to IMX682, with a slight weight reduction, the battery is also slightly less.

It does not have as many top technologies as the Xiaomi Mi 10 Extreme Commemorative Edition, but the focus is on the price of “1999”, which is enough to make competitors who are competing for the price/performance ratio all exit. This is the most cost-effective product in the 1999 price range. There is no one. If the budget happens to be in this range, you can buy it directly without any hesitation:

The Redmi K30 Extreme Edition has a 120Hz E3 material Samsung Amoled high refresh screen, this screen is unbeatable at the price of 1999 yuan! Even compared to the more expensive Redmi K30 Pro, there is no “shrink”. The contrast ratio reaches 5000000:1, the maximum brightness is 800 nits, and the peak brightness reaches 1200 nits. It has passed the HDR10+ certification and has a high refresh rate of 120Hz+ The 240Hz touch sampling rate has been further upgraded.

In terms of performance, through the comparison with Snapdragon 865 and Snapdragon 756G shown in the article, we can see that Dimensity 1000+ is a platform that is close to Snapdragon 865, whether it is CPU (the le-core gap is about 14%, more The core gap is 12%), or the GPU (5%-12% gap), which is by no means a mid-range U such as the Snapdragon 765G, which is mostly used by models in the same price range.

It is worth mentioning that, under the blessing of the MediaTek Dimensity platform, the Redmi K30 Extreme Edition even gets the special function of dual 5G standby that its top flagship does not have. Also, the 4500 mAh battery + 33W fast charge makes it have no shortcomings in daily use.

Just like the first generation of Xiaomi phones that opened the “1999” generation of price-performance legends, the Redmi K30 Extreme Edition can be bought with confidence.
