Disassembling the M2 Pro/Max new MacBook Pro: The SSD deceleration problem is serious

Apple quietly unveiled its new MacBook Pro 14 - and 16-inch laptops on the evening of Jan. 17, without a big event for them. In addition to the M2 Pro and M2 Max chip, the new 14 - and 16-inch MacBook Pro also supports HDMI 2.1 ports.

Recently, iFixit, a well-known team from abroad, disassembled the two newly released MacBook Pro models to show users the internal structure of the new MacBook Pro.

M2 Pro/Max新款MacBook Pro拆解:SSD降速问题严重

According to iFixit, unpacking the new MacBook Pro didn't reveal a lot of surprises. The overall structure of the MacBook Pro isn't any different from that of the previous macbook Pro with M1 ProMax, just replacing the chips with M2 Pro and M2 Max.

The M2 Pro follows the framework of the previous M2 chip and is built using Taiwan Semiconductor's second-generation 5nm manufacturing process. It has a 12-core CPU and 19-core GPU, and supports up to 32GB of high-speed unified memory. The M2 Max is more luxurious in terms of specs, with a 12-core CPU and a doubled 38-core GPU, as well as a 16-core neural network engine and up to 96GB of high-speed unified memory.

Apple's 12-core M2 Max tops PassMark's list of single-core performance, followed by lower-frequency M2 Pro models and M2 models, followed by Intel's 12-Gen Core HX series processors.

That says a lot about the power of the M2 series of chips, but that's because the i9-13900HK isn't yet on the market, and the number-one spot for the M2 Max may be gone when a laptop powered by this processor hits the market.

The old MacBook Pro only comes with an HDMI 2.0 port, which can output up to 4K 60 frames when used.

On the other hand, the old MacBook Pro 14 inch and 16 inch supports ProMotion technology and has a higher refresh rate. Once connected to an external 4K display, the maximum refresh rate of only 60 frames will make users feel fragmented, after all, HDMI 2.0 bandwidth is only 18Gbps.

The new M2 Pro and M2 Max 14-inch and 16-inch MacBook Pro have HDMI 2.1 ports and more than double the bandwidth to 48Gbps from 18Gbps.

This huge bandwidth boost allows the new MacBook Pro 14 - and 16-inch models to support up to 8K 60 frames of output, with a refresh rate of up to 240 frames on a 4K display, which is good news for high-brush users.

M2 Pro/Max新款MacBook Pro拆解:SSD降速问题严重

When iFixit took apart the SSD in the new MacBook Pro,It is surprising to find that the new MacBook Pro also has the original MacBook Air with the M2 chip and MacBook Pro 13 inch SSD slow down.

In previous breakdowns of the MacBook Air and MacBook Pro 13-inch models, iFixit found that Apple did indeed remove one NAND flash chip from the 256GB SSD model. The M1 had two NAND flash chips of 128GB each. But the M2 only has a 128-gigabyte NAND flash chip. As a result, the M2 SSD reads 50% slower than the M1 SSD.

That said, the base model with 512 gigabytes of storage in the new MacBook Pro has the same problem as the MacBook Air and the MacBook Pro 13 inch. The old MacBook Pro has four NAND chips with 512 gigabytes of storage compared to the new model's two. But later models are not affected.

That means the new MacBook Pro just has a new chip and even a new SSD. It's as if Apple had swapped a bowl of cold rice for dark soy sauce and reduced portions, forcing consumers to buy more expensive models.
