AMD Ryzen 9 PRO 7945
Strong multi-core performance because of the design’s 12-core/24-thread architecture. Demonstrates proficiency in software development, rendering, content production, and productivity tasks. Excels at CPU-bound jobs and programs like Blender and Adobe Premiere Pro. AMD Ryzen 7 7800X3D
Offers gaming and single-threaded performance that is leading the class. Performance in cache-sensitive applications is significantly enhanced by the additional L3 cache, despite having fewer cores than the 7945. Great for tasks that need minimal latency, such software, emulation, and code compilation requirements. You can also read Intel Core Ultra 5 125H vs 135H Mobile CPU Specs
AMD Ryzen 9 PRO 7945
Ability to run high-end current games, particularly when combined with a powerful GPU. The 3D V-Cache included in CPUs with gaming optimisation is absent, and it is not especially tuned for gaming. Due to its higher latency and lower cache, it performs worse than the 7800X3D in gaming benchmarks, despite decent frame rates in most games. AMD Ryzen 7 7800X3D
The greatest gaming CPU on the market right now. Several CPUs with more cores perform better because of its 3D V-Cache. Assassin’s Creed Valhalla, Elden Ring, and Cyberpunk 2077 may reach high frame rates. Ideal for 1080p, 1440p, and 4K games with a strong GPU. AMD Ryzen 9 PRO 7945
More power-efficient than the majority of high-end Ryzen CPUs, it has a 65W TDP rating. When there is a high load, the actual power demand might reach 88W. Better thermal efficiency and a cooler operating temperature make it perfect for small or large systems. AMD Ryzen 7 7800X3D
TDP has a 120W rating, which is much more than the Ryzen 9 PRO 7945. A full load might result in real power usage of up to 160W. Runs hotter, particularly when playing games and working for extended periods. Maintains thermal performance and boost clocks with enough cooling.

AMD Ryzen 9 PRO 7945
For tasks that require threading and multitasking, a high core count is ideal. Cooler and more energy-efficient. Extended stability and ECC are examples of professional-grade functionality. Ideal for workplaces and for developers and designers. AMD Ryzen 7 7800X3D
Gaming performance is exceptional because of the huge 3D V-Cache. Applications with only one thread benefit from higher base clocks. Perfect for gamers and streamers that want to compete. Outstanding value for the money for gamers. AMD Ryzen 9 PRO 7945
Games are not optimised, and there is no 3D V-Cache. Performance on the single thread is a little worse than on gaming CPUs. Due to less emphasis on overclocking, there is less enthusiast appeal. AMD Ryzen 7 7800X3D
Increased heat output and power drain. Performance issues with multiple threads in comparison to CPUs with more cores, such as the Ryzen 9 PRO 7945. Its 3D V-Cache architecture limits overclocking capability. You can also read AMD Ryzen 5 9600X vs Ryzen 5 7600X Performance, Price
