目次Design / size
First, about the main body design.
The new IMAC (2021) announced this time has been turned into a next -generation design that has a familiar design that has been around for about 10 years and has a pop impression.
Left: M1 iMac / Right: Conventional model
Speaking of iMac, the rounded aluminum body was characterized by thick jaws and bezels, but the IMAC with a built -in M1 chip was composed of screens and stands as before, but it was crunchy and thin.
The thickness of the main unit is 11.5 mm, and the thickness of the iPhone with a protective case has been considered, and the presence that towering with the previous dodon has disappeared considerably.
Although the part of the "jaw" continues, the bezel around the screen is narrowed, and the stand has a neat impression compared to before.
Left: M1 iMac / Right: Conventional model
Apple logo on the back.The impression has become much larger than the conventional design, but unfortunately it seems that you have to do goodbye to finish the mirror.

The body size is 54.7 x 46.1 x 14.7cm in depth.Compared to conventional products, IMAC 27 inches (5K, 2020) width 65.0 x 51.6 × depth 20.3cm, iMac 21.5 inch (non -Retina, 2017) is 52.8 × height 45.0 × depth 17.5cm.Considering that the screen size is 24 inches, it looks compact as it looks.
The body weight is 4.46kg ~.You can see that the iMac 27 inch (5K, 2020) was 8.92kg and the iMac 21.5 inch (non -Retina, 2017) was 5.66kg, so it was much lighter.

The connection location of the power cable is at the bottom of the back.The specifications passing through the power cable from the hole in the stand are the same as before, but the cable to be passed has been changed to a durable one.
The power cable is attached with a Magsafe -style magnet type.The iMac has no built -in battery, so if you hook your feet on the cable, spong!The power may be turned off immediately after passing out, but should I think it's better than the iMac it falls?
Postscript: The magnet -type power cable is a specification that will not come out unless you apply a certain amount of power.It doesn't seem to be easy to get out like MAGSAFE for MacBook.

The USB-C port mounted on the back varies depending on the number of GPU cores built.The 7 -core GPU model has only two Thunderbolt/USB4 ports, and the 8 -core GPU model has two Thunderbolt/USB4 ports and two USB 3 ports.
By the way, you may have noticed that the Ethernet port (LAN port) is gone, but there are two types of models that are not equipped with LAN ports in this M1 iMac, and models prepared in the power adapter.exist.
The model with the M1 chip GPU core is 7 core, LAN Portless.The 8 -core model seems to be included in the power adapter with a LAN port.

iMac (24インチPro, 8コアCPUと7コアGPUを搭載したApple M1チップ, 8GB RAM, 256GB)posted with カエレバ Amazonで購入するMagic Keyboard and Touch ID
The iMac 24 -inch (4.5K, M1) has Magic Keyboard, Magic Mouse and Magic Trackpad that match the body color.
Although each specification is almost the same, the Magic Keyboard is more rounded than the current model, and a new, good night mode, emoji, and dictation (listening) buttons are installed.
In addition, Magic Keyboard, which comes with the 8 -core GPU model (4 -port equipped model), is equipped with a Touch ID in the upper right, allowing you to unlock the screen by placing your finger.It can be said that it is a long -awaited change for iMac users.
By the way, this Touch ID Magic Keyboard can be obtained by the option at the time of purchase, so it is not essential to purchase a 8 -core GPU model.
screen
The display specifications of each model of the iMac are as shown in the table below.
| iMac 21.5インチ(非Retina, 2017) | iMac 27インチ(5K, 2020) | iMac 24インチ(4.5K, M1) | |
|---|---|---|---|
| screen | ・21.5インチ(非Retina)・1,920×1,280ピクセル・最大輝度320ニト・標準色(sRGB) | ・27インチ(5K)・(オプション：Nano-textureガラス)・5,120×2,880ピクセル・最大輝度500ニト・広色域(P3)・True Toneテクノロジー | ・24インチ(4.5K)・4,480×2,520ピクセル・最大輝度500ニト・広色域(P3)・True Toneテクノロジー |
When arranged in order of size on the screen, it is in the order of 27 inch iMac (5K, 2020), 24 -inch iMac (4.5K, m1), and 21.5 inch iMac (non -Retina).
The higher the screen size, the higher the screen size.The 5K model is 5,120 x 2,880 pixels, the 4.5K model is 4,480 x 2,520 pixels, and the non -Retina model is 1,920 x 1,280 pixels.
Although the value of the resolution is different between the 5K model and the 4.5K model, the size of the screen is different in the first place, so there is almost no difference in the elaborate screen (the screen density is not disclosed, but both PPIs are probably 200.For the above, if you want to work on a large screen, you should buy a 27 -inch iMac (5K, 2020), or a 24 -inch iMac (4.5k, m1) if it is a little smaller.
関連記事iMac 27インチ(5K, 2020) レビュー | IntelProcessor搭載の最新iMac、どんなユーザーにオススメ？2020-08-10By the way, this time, non -Retina models are also included in the comparison, but in the modern age of most devices, there is no longer the reason for choosing non -Retina models.The price is the same as the 24 -inch model, so if you choose a non -Retina model, we recommend a 24 -inch model.
| iMac 21.5インチ(非Retina, 2017) | iMac 27インチ(5K Retina, 2020) | iMac 24インチ(4.5K Retina, M1, 2021) | |

The quality of the screen has the same high performance between the iMac 27 inch (5K, 2020) model and the iMac 24 inch (4.5k, M1) model.The maximum brightness is 500 Nito, which supports a wide color range (P3) and True Tone technology.
TRUE TONE technology is a function that reflects images and other colors with more natural colors by adjusting the color and brightness of the display according to the surrounding light.
However, it is noteworthy that nano-texture glass can be selected only for the iMac 27 inch (5K, 2020) model.Nano-texture glass is the first glass adopted on the Apple genuine display "Pro Display XDR", which can minimize the reflection on the screen to minimize the reflection.
Since the option fee is a little expensive with a plus of 33,000 yen (tax included), I think it is necessary to carefully consider whether it is really necessary, but the desk tends to be intensely reflected on the screen, such as by the window.Recommended for those who work in the environment.
Based on the above points, if you want to minimize the image to the screen, it is better to select nano-texture glass with the iMac 27 inch (5K, 2020) model.If you don't care about the image, you'll have no problem with an iMac 24 -inch (4.5K, M1) model.
Non -Retina models have low screen quality, not far from IMAC 27 inch (5K, 2020) models and iMac 24 inches (4.5K, M1) models.The performance of the screen is directly linked to the ease of work, so if possible, select an iMac 27 inch (5k, 2020) model or an iMac 24 inch (4.5k, m1) model.

Processor
The iMac 24 -inch (4.5K, M1) has a built -in M1 chip mounted on MacBook Air and MacBook Pro.
The M1 chip is a 8 -core CPU composed of four high -performance cores and four high -efficiency core.MacBook and Mac mini equipped with the processor have become a hot topic because they have improved their performance larger than the conventional Intel processor -equipped models.
According to Apple, the iMac equipped with M1 chips has been up to 80%from the previous 21.5 -inch model.It is said that the graphic performance is up to twice the performance.
Although it is not clear which is higher than the 27 -inch iMac, the Desktop Mac "Mac MINI (M1, 2020)" equipped with the same M1 chip and the Intel processor "IMAC 27 inch (5k, 5K, 5K,When comparing the benchmark with "2020)", the following results were as follows.
| iMac (4.5K, M1)※参考：Mac mini(M1, 2020) | iMac 27インチ(5K, 2020) | |
|---|---|---|
| Processor | Apple M1 | Intel |
| シングルコアスコア | 1718程度？ | 1090〜1288 |
| マルチコアスコア | 7573程度？ | 5688〜9714 |
Based on the results above, the iMac with a built -in M1 chip is likely to have the same performance as the 8 -core model of the iMac 27 inch (5K, 2020) equipped with the Intel processor.Please tell us that it is a benchmark in Mac mini, so it is not an accurate comparison, but if this is the case, the CPU performance is enough for an entry model.

graphic
As you can see that the CPU performance is enough, it seems that many users are worried about graphic ability.
As mentioned above, the iMac 24 inch (4.5K, M1) has an M1 chip with a built -in 7 or 8 GPU cores.The graphic performance depends on the performance of the chip.
Although this is not the case because it is also released, it is likely that OpenCL will be 19619 and METAL will be around 21832 if you refer to the Mac mini benchmark with the same M1 chip as the previous section.
Although this is a diskrett type GPU level performance, the performance is still lower than that of the upper model equipped with DGPU (5K, 2020).
| 製品名 | 搭載GPU | METAL | Open CL |
|---|---|---|---|
| iMac (4.5K, M1)※参考：Mac mini (M1, 2020) | Apple M1 | 19619程度？ | 21832程度？ |
| iMac (5K, 2020) | Radeon Pro 5300 | 38121 | 35922 |
| Radeon Pro 5500 XT | 41436 | 41165 | |
| Radeon Pro 5700 | 59568 | 45221 | |
| Radeon Pro 5700 XT | 62619 | 54433 |
As a experience of the author, the work that uses graphic performance (such as editing video) can be relatively light on a Mac equipped with an M1 chip, but when editing a high -resolution video of 4k or more, it is a little shortage of power.When looking for a high graphics required for professional -level work, buy a higher -level model equipped with an intel processor (5K, 2020), or IMAC equipped with a higher Apple Silicon.It would be better to wait for the appearance.
By the way, the graphic performance of iMac 21.5 inches (non -Retina, 2017) is considerably lower than the other two models, so if you care about the graphic performance, you should not purchase iMac 21.5 inches (non -Retina, 2017).
memory
The memory capacity of each model of the iMac is shown in the table below.
| iMac 21.5インチ(非Retina, 2017) | iMac 27インチ(5K, 2020) | iMac 24インチ(4.5K, M1) | |
|---|---|---|---|
| memory | ・8GB・16GB | ・8GB・16GB・32GB・64GB・128GB | ・8GBユニファイドmemory・16GBユニファイドmemory |
| memory自力交換 | × | ◯ | × |
The 24 -inch (4.5k, M1) model and the 21.5 -inch (non -Retina) model can select 8GB, 16GB, 27 inch (5K, 2020) models 8GB, 16GB, 32GB, 64GB, and 128GB.
Memory is often compared to the size of the desk.The higher the memory capacity, increases the work space and increases the work efficiency, but the same is true for PCs.
In the case of a Mac that has many opportunities to leave multiple apps open, unlike iPhone and iPad, memory consumption tends to increase, so the memory capacity should be as large as possible.
In particular, the 27 -inch (5k, 2020) model has a large maximum capacity of the memory that can be mounted, and the user can replace and expand the memory by hand, so those who want to increase the memory capacity later.It is a recommended model for those who want to add.
関連記事27インチiMac memory増設・換装する方法 ～ 写真で手順・注意点を解説2019-08-04By the way, the iMac 24 -inch (4.5K, M1) model has a 21.5 -inch (non -Retina) model and a 27 -inch (5K, 2020) model, and has a "unified memorial citecture (UMA)".
With the introduction of this UMA, the performance of the memory has been greatly improved, and the memory consumption itself has been reduced as well as the memory transfer speed.
In fact, 8GB of MacBook Air and MacBook Pro with M1 chips was enough to do general tasks.However, it is not possible to add memory after purchase.The iMac is also a device that plays a role -like role at home, so if you are worried, if you increase the capacity to 16GB as an option, you will be able to do most of the work.

iMac (24インチPro, 8コアCPUと7コアGPUを搭載したApple M1チップ, 8GB RAM, 256GB)posted with カエレバ Amazonで購入するBuilt -in storage
The built -in storage of the iMac has a 256GB SSD as standard.
Although 256GB is a bit unacceptable, the IMAC 27 inch (5k, 2020) model and the iMac 24 -inch (4.5K, M1) model can increase the capacity with the CTO option.Each has an iMac 27 -inch (5K, 2020) model up to 8TB, and the iMac 24 inch (4.5K, M1) model can be increased to 1TB.
| iMac 21.5インチ(非Retina, 2017) | iMac 27インチ(5K, 2020) | iMac 24インチ(4.5K, M1) | |

| ストレージ | ・256GB SSD・1TB Fusion Drive | ・256GB SSD・512GB SSD・1TB SSD・2TB SSD・4TB SSD・8TB SSD | ・256GB SSD・512GB SSD・1TB SSD |
If the storage capacity is sufficient within 1TB, either Mac 27 inch (5K, 2020) model or iMac 24 inch (4.5K, M1) model would be fine, but if 1TB is not enough, iMac 27The inch (5K, 2020) model will be the choice and the options should be quite simple.
By the way, for a 21.5 -inch model (non -Retina) model, you can also select a 1TB Fusion Drive, but it is not very recommended personally because the performance is lower than the SSD.If you need a large capacity storage, you want to choose an iMac 27 inch (5k, 2020) model or an iMac 24 inch (4.5k, M1) model.
Audio performance
If you enjoy music and movies directly from iMac, the performance of the speaker is one of the important factors.
Of the 21.5 -inch (non -Retina) model, 27 inch (5K, 2020) model, 24 -inch (4.5K, m1) model, the 24 -inch (4.5K, M1) model has the best speakers.

6 Speaker systems that are faithful to the original sound equipped with Force Can Singing Woofer, a wide stereo sound, and a spatial audio when playing a video in Dolby Atmos, more than a normal stereo speaker installed in the other two models.You can enjoy quality sounds.
In addition, the 24 -inch (4.5K, M1) model has the highest performance for the microphone.The studio quality with high signal vs. a ratio and directional beam forming can deliver clear audio with low noise to the other party at a web meeting.
network
The network corresponding to iMac is as follows.Whether the point corresponds to the latest Wi-Fi standard "Wi-Fi 6".
| iMac 21.5インチ(非Retina, 2017) | iMac 27インチ(5K, 2020) | iMac 24インチ(4.5K, M1) | |
|---|---|---|---|
| network | ・802.11ac Wi-Fi・Bluetooth 4.2 | ・802.11ac Wi-Fi・Bluetooth 5.0 | ・802.11ax Wi-Fi 6・Bluetooth 5.0 |
As you can see from the table above, the only iMac corresponding to Wi-Fi 6 is iMac 24 inch (4.5K, M1).Other than that, the previous generation Wi-Fi 5 will be supported.
Wi-Fi 6 has a faster communication speed than before, enjoys video distribution services and online games comfortably, and uses stable communication even if the number of simultaneous connections increases.Therefore, there is an advantage that the line is less crowded even if there are many devices connected to Wi-Fi, such as IoT home appliances.
Despite the need for a corresponding router, Wi-Fi 6 will definitely be the standard in the future (it is no longer a flexible), so the device to be purchased in the future will still purchase the one that supports Wi-Fi 6.Is better.

Color lineup
The iMac 24 -inch (4.5K, M1) has a total of seven colors.The 7 -core GPU model is available in four colors, blue, green, pink, and silver.The 8 -core GPU model is available in seven colors: blue, green, pink, silver, yellow orange, and purple.
Intel processor IMAC, on the other hand, is developed only for silver.If you want a bright and pop color model, buy an iMac 24 inch (4.5K, M1).If you want a conventional dull glossy silver color iMac, buy an iMac 21.5 inch (non -Retina, 2017) or iMac 27 inch (5K, 2020).
price
The price of each model of the iMac is as follows.
| iMac 21.5インチ(非Retina, 2017) | iMac 27インチ(5K, 2020) | iMac 24インチ(4.5K, M1) | |
|---|---|---|---|
| price(税込) | 132,800円〜 | 3.1GHzモデル：214,280円〜3.3GHzモデル：238,480円〜3.8GHzモデル：274,780円〜 | 2ポートモデル：154,800円〜4ポートモデル：177,800円〜 |
The cheapest is the iMac 21.5 inch (non -Retina, 2017), followed by the iMac 24 inch (4.5k, m1), which is the highest, the iMac 27 inch (5K, 2020) model.The price lineup is approximately easy to understand.
The highest cost performance among them is probably the iMac 24 inch (4.5k Retina, M1) equipped with an M1 chip.The M1 chip, which is compatible with the Apple system and is compatible with the system, should have been sufficient to achieve the design of the next -generation iMac and the affordable price.
Although some criticism (?) For the fact that the "jaw" remains and the pop and cheap design has been raised from some, the new design is renewed and multi -color development for the first time in about 10 years.I feel welcomed from.It seems that the price is somewhat reasonable.
However, I am worried that the graphic performance is more likely to be lower than the upper model IMAC 27 inch (5K, 2020).Although the CPU performance is almost enough, many users are seeking higher performance with desktop models.
As mentioned above, if you are looking for a high graphics required for professional -level work, you can buy a higher -level model IMAC 27 inch (5K, 2020) equipped with Intel processors, or the appearance of an iMac equipped with a higher Apple Silicon.It seems better to wait for.
By the way, the cheapest model is iMac 21.5 inch (non -Retina, 2017), but considering that the Intel processor mounted on the model is the 7th generation and three years ago, it is only cheap.I guess you can think of it.Although it is excellent in cost, it is not good in performance, so I do not recommend purchasing the product very personally.By the way, the price difference from the iMac 24 inch (4.5K, M1) equipped with an M1 chip is only about 20,000 yen.
Summary: Consider which model to buy
I've been comparing so far, but what model is the perfect among the three iMac?I tried to divide some cases, although it is somewhat concise so that it is easy for beginners to understand, so please check it out.
As you can see from the above division, the current iMac lineup is recommended either iMac 5K (27 inch, 2020) or iMac 4.5K (24 inch, M1).I am not very recommended because I think that iMac 21.5 inches (non -Retina, 2017) will not be worth the cost and performance, but if you want to buy an iMac a little cheaper, it may be an option.。
I think the "border" of the decision should be a graphic performance, which should be purchased, the iMac 5K or the M1 iMac.It is an IMAC 24 -inch model that has a Disk -type GPU level performance with an M1 chip, but depending on the configuration, the graphic performance may be inferior to the iMac 5K.If you move the 3D model at a high frequency or edit a high -resolution video, the iMac 5K will still be the option of purchasing.The screen size is as wide as 27 inches, so it should be easier to work.
It is also attractive that iMac 5K can add memory with the user's own hands.The M1 Mac can operate comfortably even if the memory capacity is low, so it may not be necessary to install a large memory as before, but IMAC 24 inches (4.5k, M1).In the case, the memory capacity must be determined at the time of purchase, so the ease of expansion and replacement at any time after purchase can be said to be higher in iMac 5K.
The appeal of iMac 24 inch (4.5K, M1) is that Apple Silicon (M1) enhances performance from the conventional 21.5 -inch model.The processing performance is as high as the upper model, and photos and videos are also practical.Even if it is not a professional level, if you do a general work or a little step -up work, you will probably be satisfied enough.
The body size has become compact, the price is relatively affordable, and the Touch ID is finally available.It can be said that it is a good device that can be used in a small housing environment in Japan.It seems good to leave it as a main PC.
