Summary
About the AMD K6-III+ 450ACZ CPU
The AMD K6-III+ 450ACZ is an end-of-life 1-core (1-thread) processor built for the mobile CPU market. It launched in Q2 2000 with a suggested retail price of $140. It is part of AMD's K6-III+ lineup, which is based on the Sharptooth microarchitecture. The K6-III+ 450ACZ is compatible with AMD Super Socket 7 motherboards and is fabricated on a 180 nm manufacturing process.
Memory and Cache
In terms of cache, the K6-III+ 450ACZ has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 64 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 256 KB, is larger but slower than the L1.
Cores and Clock Speeds
The K6-III+ 450ACZ is a single-core and single-threaded CPU, making it not capable of processing multiple computational tasks in parallel. The base clock speed of the CPU is 450.0 MHz. Higher clock speeds result in higher performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.
Integrated Graphics
The K6-III+ 450ACZ does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
About the AMD Ryzen Threadripper PRO 9955WX CPU
The AMD Ryzen Threadripper PRO 9955WX is a 16-core (32-thread) processor built for the workstation CPU market. It launched in Q3 2025 with a suggested retail price of $1,649. It is part of AMD's Ryzen Threadripper lineup, which is based on the Zen 4 microarchitecture. The Threadripper PRO 9955WX is compatible with AMD Socket sTR5 motherboards and is fabricated on TSMC's 4 nm manufacturing process.
Memory and Cache
The Ryzen Threadripper PRO 9955WX supports DDR5 memory and features a octa-channel memory controller, allowing it to utilize 8 memory modules simultaneously. In terms of cache, the Ryzen Threadripper PRO 9955WX has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 64 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 1 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 64 MB.
Cores and Clock Speeds
The Ryzen Threadripper PRO 9955WX features 16 total cores which can process 32 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 4.5 GHz, and it can boost up to 5.4 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is unlocked, enabling overclocking for those seeking to push the CPU's performance further.
Integrated Graphics
The Ryzen Threadripper PRO 9955WX does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
