AMD Ryzen 9 Pro 9945 VS AMD Ryzen Threadripper Pro 9995WX

The AMD Ryzen 9 Pro 9945 and AMD Ryzen Threadripper Pro 9995WX are both desktop processors, but they have some notable differences in their specifications. The Ryzen 9 Pro 9945 comes with integrated graphics, while the Threadripper Pro 9995WX does not, making the former potentially more suitable for systems without dedicated graphics cards.

In terms of thermal design power (TDP), the Ryzen 9 Pro 9945 has a much lower rating of 65W, which is significantly less than the 350W TDP of the Threadripper Pro 9995WX. This indicates that the 9995WX likely requires much more robust cooling solutions to maintain optimal performance. Both processors have a semiconductor size of 4 nm, suggesting that they share similar manufacturing technology. Both also feature the same maximum CPU temperature of 95 °C, which indicates a common thermal limit under load.

Both processors support PCIe 5.0, offering faster data transfer speeds, and they are both 64-bit compatible, allowing them to handle modern software and workloads efficiently. Overall, while they share some similarities, such as the semiconductor size and support for PCIe 5.0, the major differences lie in the presence of integrated graphics, TDP, and the need for cooling, with the Ryzen 9 Pro 9945 being a lower-power option compared to the high-performance Threadripper Pro 9995WX.

The AMD Ryzen 9 Pro 9945 and AMD Ryzen Threadripper Pro 9995WX vary significantly in terms of performance specifications. The Ryzen 9 Pro 9945 has a CPU speed of 12 cores at 3.4 GHz, with a turbo clock speed reaching up to 5.4 GHz. In contrast, the Threadripper Pro 9995WX features a much larger CPU configuration, with 96 cores running at 2.5 GHz, also reaching a turbo clock speed of 5.4 GHz. This massive difference in core count—24 threads for the Ryzen 9 Pro 9945 versus 192 threads for the Threadripper Pro 9995WX—suggests that the Threadripper is designed for tasks requiring high parallel processing, such as heavy multitasking or professional applications.

When it comes to cache, the Ryzen 9 Pro 9945 has an L2 cache of 12 MB, L3 cache of 64 MB, and an L1 cache of 960 KB. On the other hand, the Threadripper Pro 9995WX comes with significantly larger caches, with 96 MB of L2 cache, 384 MB of L3 cache, and 7680 KB of L1 cache. These larger caches on the Threadripper Pro 9995WX could contribute to improved performance in data-intensive tasks by providing more on-chip storage for frequently accessed data.

Both processors have the same turbo clock speed of 5.4 GHz, but the Threadripper Pro 9995WX features an unlocked multiplier, allowing for overclocking. The Ryzen 9 Pro 9945, however, has a locked multiplier, limiting its overclocking potential. Neither processor utilizes big.LITTLE technology, and both feature the same L2 and L3 cache sizes per core (1 MB/core for L2 and 4 to 5.33 MB/core for L3), showing some level of similarity in their architectural design. Despite these similarities, the large differences in core count and cache size make the Threadripper Pro 9995WX far more powerful in terms of handling highly parallel workloads.

The benchmark results for the AMD Ryzen 9 Pro 9945 and AMD Ryzen Threadripper Pro 9995WX show a significant difference in overall performance. The Ryzen 9 Pro 9945 has a PassMark result of 50,113, while the Threadripper Pro 9995WX achieves a much higher PassMark result of 176,341. This vast disparity indicates that the Threadripper Pro 9995WX is designed for much more demanding workloads and outperforms the Ryzen 9 Pro 9945 in multi-threaded tasks.

When it comes to single-threaded performance, both processors have similar scores, with the Ryzen 9 Pro 9945 achieving a result of 4,623, and the Threadripper Pro 9995WX slightly lower at 4,575. This small difference suggests that for tasks reliant on single-threaded performance, the two processors are nearly on par.

In summary, while both processors show strong performance, the Threadripper Pro 9995WX excels in multi-threaded tasks, as reflected in its much higher overall PassMark score. The Ryzen 9 Pro 9945, however, delivers comparable single-threaded performance, making it a solid choice for applications that do not require massive parallel processing power.

The memory specifications for the AMD Ryzen 9 Pro 9945 and AMD Ryzen Threadripper Pro 9995WX show clear differences in terms of speed, capacity, and configuration. The Ryzen 9 Pro 9945 supports a maximum RAM speed of 5600 MHz, while the Threadripper Pro 9995WX supports a faster maximum RAM speed of 6400 MHz. Both processors are compatible with DDR5 memory, indicating modern memory support.

When it comes to memory channels, the Ryzen 9 Pro 9945 has 2 channels, while the Threadripper Pro 9995WX has 8 channels, allowing for significantly more memory bandwidth on the Threadripper. This could be beneficial in scenarios where large amounts of data need to be transferred quickly. The Ryzen 9 Pro 9945 can support up to 192GB of maximum memory, while the Threadripper Pro 9995WX can support a massive 2000GB of maximum memory, making it more suited for high-memory-demand applications.

Both processors support ECC (Error-Correcting Code) memory, which helps ensure memory reliability by detecting and correcting errors. While both products support this feature, the Ryzen 9 Pro 9945 has a more moderate memory configuration, while the Threadripper Pro 9995WX is designed to handle much larger and faster memory configurations, making it more suited for heavy-duty workloads that require significant memory resources.

Both the AMD Ryzen 9 Pro 9945 and AMD Ryzen Threadripper Pro 9995WX share identical features when it comes to instruction sets, multithreading, and security. Both processors support the same set of instruction sets, including MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2, which are commonly used for accelerating various types of computational tasks and improving performance in modern applications.

Both processors also support multithreading, which allows each core to handle multiple threads simultaneously, enhancing performance in multi-tasking and heavily threaded workloads. Additionally, both products have the NX bit feature, which adds an extra layer of security by preventing the execution of certain types of malicious code.

In summary, there are no differences between the two processors in terms of these specific features. They both offer the same instruction sets, multithreading capabilities, and security features, making them equally equipped for modern software and security demands.
