Top Macbook upgrade to fully equipped iMac experience sharing ~

It has been more than a month since I upgraded from a top-of-the-line macbook to a full imac. The difference in actual use is not small. Of course, in order to be more comparative, I will compare some of my Macbook combinations ~ Share the similarities and differences in my actual use, hoping to help you purchase iMac and MBP ~ # configure The Macbook Pro is a 2018 model, with optional i9 + vega 20 + 32G memory, and the hard drive is 500G. Daily use with Dell U2720qm and Samsung 32: 10 43-inch ultra-wideband fish screen, and the docking station uses Dock Pro and a full set of 10 Gigabit networks and one-ticket servers The iMac is a 2020 model, with optional nano-coating + i9 + 5700xt + 10 Gigabit network card, 8T hard drive, and 128G memory added later. Home alone. Let's start with the running scores. Macbook's single-core score is roughly 1100 points, imac's single-core score is in the early 1300 points, and the multi-core scores of both are roughly the number of cores * 1000. I think this will be maintained until intel has any big breakthrough. This rule. # heat dissipation The Macbook is known to use the legendary single heat pipe design. In the case of continuous high load of cpu and gpu at the same time, it only takes 10 ~ 15 minutes for the frequency of cpu to drop to an almost unusable frequency (it has reached 800Mhz in actual use), which is still in the case of being lifted by the bracket. Lay flat on the table, and the frequency reduction will be faster. After the frequency reduction, the performance of the macbook is only about 40% of the previous performance. Compared with the imac, it has dropped from about 75% to about 30%. This is the main reason why I didn't choose the 2020 fully equipped Macbook Pro 16-inch in the first place. The frequency reduction has not been completely solved on the 16-inch MBP, but has only been improved. In terms of iMac, under long-term high load, heat dissipation does not drag down the performance a lot, and the cpu frequency can be kept above the basic frequency of 3.6 and between 4.1 Ghz, which is completely acceptable. If the CPU is baked alone, it can maintain 4.0 Ghz, and the temperature reaches 100 °C at this time. # Cooling Strategy In terms of cooling strategy, iMac performs better than the independent display state. iMac can run quietly most of the time, but under high load, the fan speed will rise to more than 2,900 rpm, and the sound will be muffled. In particular, when an external monitor is connected, MBP will force the use of independent display. At this time, the fan is more sensitive. If you run some program, the fan speed will rise to above 3000 rpm and start to make sound. If the load is higher, it will run at full speed of 6000 rpm. Therefore, in my daily use, that is, when I connect an MBP external monitor, the noise performance of iMac is better than that of MBP. # screen When MBP is externally connected to U2720, the measured charging power can reach 80W (native adapter 87W, 2720qm nominal 90W). However, if the charging power of your display screen is only 65W, the power may slowly decrease in daily use. When watching dramas or movies, the MBP screen tends to reflect its own shadow when encountering a dark background, which affects the viewing experience. The iMac is equipped with the same nano-coating as the Pro Display XDR, so there is no reflective problem, but the matte screen of the U2720QM also has no reflective problem. The light nano-coating is enough for a U2720, so the effect is good, but the price It's not worth it. At the same time, the nano-coating makes the screen delicate, and it can no longer miraculously wipe the QAQ with a napkin. Although I printed a LOGO with great faith, it is very expensive to lose it! # Scalability MBP is 2 Thunderbolt chips with a total of 4 Thunderbolt ports. I usually connect Dock Pro (with a second-generation SD card reader, 10 Gigabit network card and several USB Type A ports, and a DP port), U2720qm (by the way, as a power supply), C43J ultra-widescreen (equivalent to two 16:10 seamless, office artifact). The disadvantage of MBP is that all powerful docking stations have a brick power supply, and an additional portable docking station is needed to be taken out. The iMac has 2 Thunderbolt ports, a second-generation card reader, an optional 10 Gigabit network card and 4 USB Type A ports. Because my own cables are completely inverted to the Type C port, four Type A ports are a bit too much. It would be better if I replaced them with two Type C and two Type A USBs. When I went out, I prepared two Thunderbolt hard drive boxes (thanks to the original recommendation) to use with two 2T SN750s, one of which is mainly used as a Time Machine. A piece to back up important data. It feels hot to the touch, but the actual temperature measured with a temperature gun is not high, less than 50 ℃. # Portability MBP is an advantageous project, but for me, it's not that advantageous except that it can be taken out of the door. Unplugging the device connected to MBP is a headache, especially when using an external GPU, you need to turn off all software using the GPU. The same goes for external hard drives. It can't be done in a few minutes And the portability of the iMac. Emmm, it can only be checked by airplane in the original packaging, and there is no additional shipping fee exceeding 23kg or 158CM, that's all. # memory In terms of memory, MBP chooses 32G, which is supported by a server at home, and the development environment is all running on a virtual machine. 32G is completely enough. Occasionally, cutting videos will lead to insufficient memory, which will be stuck later, but taking MBP alone Come out, 32G is not enough to open a virtual machine. imac's own full memory of 128G (8G is given by default, Apple is really ashamed of this matter). As mentioned earlier, the development environment is all virtual, and there is no server blessing, so the virtual machine can only run on imac. Neither of them has encountered obvious bottlenecks and is a relatively comfortable option. # video card In terms of graphics cards, iMac has not encountered obvious bottlenecks. The performance of 5700XT with 16G video memory can only be said to be quite satisfactory. As for MBP, due to power and heat dissipation issues, vega 20 didn't perform well. At present, prores encoding has been used for some time, and multi-clip playback is not a big problem, but it is a bit hard disk. # hard disk The hard disk is mainly a matter of convenience and capacity, but the speed is secondary. Macbook is a 500G hard disk. During the two years of use, I have been anxious about the capacity of the hard disk countless times and regretted the original choice of capacity. I should have chosen 4T. At home, the macbook is always connected to a server at home using 10 Gigabit. The total original capacity of the two nas is 192TB. Compared with the built-in hard disk of the imac, the 10 Gigabit network can only run 1,000 megabits per second. For more than a dozen 30 ~ 50G data a day, it is still much slower. Two nas have tried to use 40G network connection, but there are still various dissatisfaction points. But 10 Gigabit is completely enough for online video cutting. Even for 4k prores hq encoded files, the 1000Mbps bit rate can store 10 files at the same time. On the imac side, I filled the hard drive to 8T. On the one hand, it is because the single T price of the imac hard drive is actually not high. The 8T is in the early 1W6, which is equivalent to a 1TB capacity in the early 2000s. It is difficult for you to find a brand new one in the market. The nvme hard drive with high speed and non-slow speed is only sold for 2,000 per TB unit price. It's just that the total price of 8TB is a bit high. # Other similarities and differences There are still many similarities and differences in other features. For example, the bezel of iMac is thicker, and the bezel of MBP is slightly thinner. The keyboard light of MBP will come on. I am not an rgb fan, and I don't really like marquees like Razer. A white light like MBP is good. It is quite useful when the lights are not turned on at night. FILCO's 67-key Xiaobai and 87-key Xiaobai will not light up, and of course Magic Keyboard will not light up QAQ either By the way, both iMac and MBP come with their own T2 chip with bugs, which is another story again.. # Summary Overall, the experience of upgrading from MBP to fully equipped iMac this time is good. As the last or two generations of Intel-based iMacs, this upgrade is relatively large, except that the appearance is basically unchanged. The cpu and gpu inside all use mainstream configurations (i9-10910 and 5700xt), and the other audio, microphone, camera, hard disk, nano coating, t2 chip, 10 Gigabit, and second-generation sd card reader can be upgraded. Upgraded. I didn't encounter a big bottleneck in use, and it was very quiet most of the time. I did what I gave it. The main frequency of the CPU was within an acceptable range even under high load, so it would not hold back the GPU. There is no anxiety about hard disk capacity when using a macbook with a 512G hard disk. It comes with a large-size screen with good quality. When the 128G memory is not supported by the server, there is no bottleneck in turning on the virtual machine. # Other options considered before buying Option one: The 4W3 found on Xianyu is an optional Mac Pro with a 4T hard drive. The main reason for not choosing is that I need to buy an additional monitor, and I feel that the built-in 580x is not enough and I need to upgrade the W5700 myself. It is inconvenient to sell the 580 second-hand, and it is inconvenient to check it in. Option 2: Fully equipped with the 2020 16-inch Macbook Pro, and sell the 15-inch one in my hand (back to about 1W4). The reason for not choosing was mentioned earlier. The heat dissipation problem, which caused the CPU downfrequency problem to not be solved. It's hard for me to choose another Macbook Pro. Option 3: Finally, this iMac comes with a screen, all the extensions it needs, the performance is quite satisfactory, and there is no obvious bottleneck. imac is considered a cost-effective product in the mac production line. Many people should still be struggling with the arm version of imac or the frame of the horse racing. It is not used on multiple screens. In fact, the frame does not affect the use too much, but it is ugly.
