M5 MacBook Pro Outpaces Framework Laptop 13 Pro in Memory Bandwidth, but Modular RAM Still Has a Big Advantage
The move to LPCAMM2 memory is changing what users can expect from modern laptops. Instead of being locked into soldered RAM, notebooks like the Framework Laptop 13 Pro can offer replaceable, upgradeable memory while still using efficient LPDDR5X technology. That flexibility is a major win for repairability and long-term usability, especially for users interested in AI workloads.
However, modular memory does not automatically mean equal performance. When compared with the M5 MacBook Pro, the Framework Laptop 13 Pro falls behind in raw memory bandwidth, and that gap can directly affect AI performance.
Both laptops use LPDDR5X memory, but they do not run it at the same speed. The Framework Laptop 13 Pro’s LPCAMM2 module operates at 7,467MT/s, while the M5 MacBook Pro uses faster 9,600MT/s soldered memory. That difference in memory speed leads to a noticeable bandwidth advantage for Apple’s laptop.
In a STREAM memory benchmark shown by Alex Ziskind, the M5 MacBook Pro reached around 136,000MB/s of memory bandwidth. The Framework Laptop 13 Pro, using its current LPCAMM2 configuration, achieved about 97,775MB/s. That gives the M5 MacBook Pro roughly 39 percent higher bandwidth, which can make a real difference in tasks that rely heavily on fast memory access.
This performance gap is especially important for AI workloads. Running large language models locally depends not only on the processor but also on how quickly the system can move data through memory. Higher memory bandwidth can improve token generation speeds, meaning the M5 MacBook Pro is likely to produce faster results when running the same AI model under similar conditions.
Still, the reason for the difference is not simply that Apple uses soldered RAM. The real factor is memory speed. The M5 MacBook Pro’s LPDDR5X memory runs at 9,600MT/s, while the Framework Laptop 13 Pro’s LPCAMM2 module runs at 7,467MT/s. If Framework were able to offer LPCAMM2 modules at 9,600MT/s, the performance gap could shrink significantly.
That is where the future of LPCAMM2 becomes interesting. Faster LPCAMM2 modules have already been demonstrated by memory manufacturers, so the technology is capable of reaching higher speeds. The challenge is availability, supply chain access, and whether laptop makers can source those modules at scale.
For now, the M5 MacBook Pro has the clear advantage in memory bandwidth and AI responsiveness. Its faster soldered memory gives it stronger performance in bandwidth-sensitive applications, including local AI model execution, creative workflows, and other demanding tasks.
But the Framework Laptop 13 Pro has a different kind of advantage: upgradeability. Soldered RAM may be fast, but it cannot be replaced or expanded after purchase. Buyers must choose their memory configuration at checkout and live with that decision for the life of the machine.
Framework’s modular approach gives users more freedom. Even if current LPCAMM2 modules are slower, owners may eventually be able to install faster or higher-capacity memory as better modules become available. That could be especially valuable for AI users who want to run larger models locally, where having more RAM can matter just as much as having faster RAM.
The trade-off is cost. LPCAMM2 upgrades are expected to be expensive, particularly for high-capacity modules. Still, for users who prioritize repairability, customization, and future upgrades, the Framework Laptop 13 Pro offers something the M5 MacBook Pro cannot: the ability to evolve over time.
The takeaway is simple. The M5 MacBook Pro currently delivers much higher memory bandwidth thanks to its faster 9,600MT/s LPDDR5X memory, giving it an edge in AI workloads and other memory-intensive tasks. The Framework Laptop 13 Pro, with its 7,467MT/s LPCAMM2 module, is slower today, but its modular design could become a major strength once faster LPCAMM2 memory becomes widely available.
For buyers focused on maximum performance right now, the M5 MacBook Pro has the lead. For those who value upgradeability and long-term flexibility, the Framework Laptop 13 Pro remains one of the most interesting options in the laptop market.
