AMD Ryzen 9 Pro 9945 VS Apple M5

The AMD Ryzen 9 Pro 9945 is a desktop processor, while the Apple M5 is designed for laptops, so the two differ in their intended use cases. This distinction affects their form factors, with the Ryzen 9 Pro 9945 tailored for desktop systems, and the M5 optimized for portable devices like laptops.

Both processors include integrated graphics, meaning neither requires a separate GPU for basic graphical tasks. The Ryzen 9 Pro 9945 uses a 4 nm semiconductor size, while the M5 uses a smaller 3 nm process. This difference in semiconductor size may affect factors like power efficiency and performance, though it’s not directly indicated by the provided specs.

Both processors support 64-bit computing, which is standard for modern processors, ensuring they can run modern software without compatibility issues. While the Ryzen 9 Pro 9945 is specified as having integrated graphics, the M5 also offers integrated graphics, indicating both processors handle graphical tasks internally.

The AMD Ryzen 9 Pro 9945 has a CPU speed of 12 cores running at 3.4 GHz, with a clock multiplier of 34. In comparison, the Apple M5 has a more complex speed configuration with 4 cores running at 4.6 GHz and 6 cores at 3.2 GHz, with a clock multiplier of 46. This suggests that the Apple M5 may provide higher peak performance on its higher-speed cores, while the Ryzen 9 Pro 9945 offers a more uniform core performance.

When it comes to CPU threads, the Ryzen 9 Pro 9945 supports 24 threads, while the Apple M5 is limited to 10 threads. This indicates that the Ryzen 9 Pro 9945 can handle more simultaneous processes or tasks than the M5, which could benefit multi-threaded workloads.

The L2 cache of the Ryzen 9 Pro 9945 is 12 MB, while the M5 has a slightly larger L2 cache of 16 MB. For L1 cache, the Ryzen 9 Pro 9945 has 960 KB, significantly larger than the M5’s 320 KB. These differences in cache sizes could impact the speed at which both processors access frequently used data. Additionally, the M5 uses big.LITTLE technology, which is not present in the Ryzen 9 Pro 9945. This means the M5 may switch between high-performance and power-efficient cores based on demand, potentially enhancing energy efficiency in certain tasks, though it is not applicable in the Ryzen 9 Pro 9945.

The AMD Ryzen 9 Pro 9945 supports a maximum RAM speed of 5600 MHz, while the Apple M5 can handle faster RAM with a maximum speed of 6400 MHz. Both processors support DDR5 memory, which is the latest standard for faster data transfer rates compared to previous generations.

When it comes to maximum memory capacity, the Ryzen 9 Pro 9945 can handle up to 192GB of RAM, significantly higher than the 64GB maximum supported by the M5. This makes the Ryzen 9 Pro 9945 more suitable for memory-intensive tasks or systems requiring large amounts of RAM.

In terms of error-correcting code (ECC) memory, the Ryzen 9 Pro 9945 supports ECC, which provides greater reliability by detecting and correcting memory errors. The Apple M5, however, does not support ECC memory, which may be a consideration for users prioritizing data integrity in their workloads.

Both the AMD Ryzen 9 Pro 9945 and the Apple M5 include the NX bit feature. The NX bit, short for No eXecute bit, is a security feature that helps protect against certain types of malicious software by marking areas of memory as non-executable. This provides an additional layer of defense for both processors against certain types of attacks.

Since both processors share this feature, they are equally capable of providing this specific security benefit, ensuring a certain level of protection in their respective systems.

As such, there is no difference between the two products in terms of the NX bit, with both offering this feature for enhanced security.
