It has been predicted that the MacBook Pro, which is expected to be equipped with an organic EL (OLED), will be equipped with the same M5 Ultra configuration as the Mac Studio. However, this is just an independent prediction and is at odds with previous reports. Even if it were to be realized, it would be difficult to match Mac Studio in terms of performance during continuous operation. We will decipher the conditions under which Ultra can be installed based on power and heat constraints.
Prediction of new configuration for MacBook Pro equipped with organic EL (OLED)
The forecast was made by an analyst at research firm Omdia. According to reports from overseas media, Apple is expected to prepare M5 Ultra configurations for models to be launched by early 2027. There are also indications that the same model will be released under the name “MacBook Ultra.”
Meanwhile, the only chips mentioned in previous reports were the M5 Pro and M5 Max. Apple hasn’t put Ultra-branded chips in its notebook Macs so far.
M5 Ultra is the top-of-the-line Apple silicon that Apple has only put on stationary devices. Previous versions of Ultra have adopted a configuration in which two Max units are connected and run as one. While computing power can be greatly increased, power consumption and heat generation also increase in the same direction.
From the perspective of following the generational changes in Apple silicon, I believe that the reason why it has been limited to stationary devices is the increase in power and heat generation. The launch date is expected to be by early 2027, which is still a long way off.
Three walls to put Ultra on a notebook
There are three main barriers: power, heat radiation, and the casing.
- Battery: If you run it at full power, the drive time will be greatly reduced.
- Heat dissipation: Processes heat in a much smaller volume than a stationary machine
- Housing: Gaining room for cooling increases thickness and weight
How long does the battery last?
Mac Studio is a product that requires constant connection to a power source, so power consumption constraints are loose. The same design doesn’t work for notebooks. There is an upper limit to the cell capacity that can be built-in, and the drive time itself determines the product value.
When running the Ultra configuration at full power, battery life is expected to be significantly lower than current models. A design that reduces performance when there’s no power supply would work, but it wouldn’t be called a “portable Mac Studio.”
Where does the heat go?
A stationary machine can accommodate a large heat sink and large diameter fan. The usable volume of a laptop is very limited, and the bottom touches your knees and your fingers rest on the keyboard surface. The upper limit of surface temperature must also be kept low.
Even with the current MacBook Pro, when exporting for a long time, the main unit may get warm and the fan may continue to run. Since this is the case with the M5 Max, if the Ultra is housed in the same housing, there will be even less room for heat to escape.
The key is cooling, which spreads the heat over the entire surface instead of storing it in one point. In recent years, Apple has been making improvements in the same direction with its thin products. The deciding factor is whether this cooling can be brought to the top of the line notebook model.
Will the casing be thicker?
The surest way to gain cooling room is to make the body thicker. The choice to increase the thickness conflicts with the MacBook Pro’s pursuit of thinness.
There is also a plan to increase the screen size to increase volume, but this would involve reviewing the current configuration of 14 inches and 16 inches. The inclusion of Ultra does more than just increase chip options.
How does it differ from Mac Studio?
Apple will release the new Mac Studio featuring M5 Max and M5 Ultra on September 22, 2026. Stationary machines can be designed with plenty of power and cooling, so they have an advantage in performance during continuous operation.
| comparison axis | Mac Studio | MacBook Ultra (rumor) |
|---|---|---|
| power supply | Constant connection required | Battery powered |
| Performance during continuous operation | Slow to hit the ceiling | Cools down quickly at upper limit |
| Time of introduction | Released on September 22, 2026 | Until early 2027? |
| Suitable use | work that continues to turn | Short processing time on site |
*This table is organized based on current information and the author’s analysis, and is not an actual measurement.
The two are arranged based on their different uses, not in a hierarchical relationship. Mac Studio is used for continuous work, and MacBook Ultra is used for quick work on site. This division is realistic.
What criteria should Japanese users choose?
If the yen continues to depreciate, the yen-denominated price of the higher-ranking components will increase. Even if you choose the Ultra configuration, a MacBook Pro with M5 Max will suffice for most purposes.
It might be worth considering for people who want to complete heavy processing on the go. If you just go back and forth between home and work, having two Mac Studio and MacBook Air will be better in terms of total cost and work efficiency.
Purchasing decisions are not measured by the upper limit of performance, but by how much time it saves you in actual work.
What should be noted is not whether it is installed or not, but how far Apple can build cooling into a notebook type. When a follow-up report comes out, it is a turning point to measure the accuracy of the rumor.
