AMD Ryzen Threadripper PRO 3975WX vs Intel Core i9-7940X

The AMD Ryzen Threadripper PRO 3975WX is a 32-core (64-thread) processor built for the workstation CPU market. It launched in Q3 2020 with a suggested retail price of $2,749. It is part of AMD's Ryzen Threadripper lineup, which is based on the Zen 2 microarchitecture. The Threadripper PRO 3975WX is compatible with AMD Socket WRX8 motherboards and is fabricated on TSMC's 7 nm manufacturing process.

Memory and Cache

The Ryzen Threadripper PRO 3975WX supports DDR4 memory and features a octa-channel memory controller, allowing it to utilize 8 memory modules simultaneously. In terms of cache, the Ryzen Threadripper PRO 3975WX 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 512 KB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 128 MB.

Cores and Clock Speeds

The Ryzen Threadripper PRO 3975WX features 32 total cores which can process 64 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.5 GHz, and it can boost up to 4.2 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.

Integrated Graphics

The Ryzen Threadripper PRO 3975WX does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.

Benchmark Performance & Value

The Ryzen Threadripper PRO 3975WX has the 129th best 3DMark 11 Performance Physics score among the 768 benchmarked CPUs in our database. It achieves 45.18% of the performance of the best benchmarked CPU, the AMD Ryzen 9 9950X. Its 17,290 score and $2,749 launch price (MSRP) gives it a performance per dollar of 6.29. This is the 224th best in value for the 3DMark 11 Perf. Physics benchmark.

The Intel Core i9-7940X is an end-of-life 14-core (28-thread) processor built for the desktop CPU market. It launched in Q3 2017 with a suggested retail price of $1,399. It is part of Intel's Core i9 lineup, which is based on the X-Series 7th Gen microarchitecture. The i9-7940X is compatible with Intel Socket 2066 motherboards and is fabricated on Intel's 14 nm manufacturing process.

Memory and Cache

The Core i9-7940X supports DDR4 memory and features a quad-channel memory controller, allowing it to utilize 4 memory modules simultaneously. In terms of cache, the Core i9-7940X 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 19.25 MB.

Cores and Clock Speeds

The Core i9-7940X features 14 total cores which can process 28 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.1 GHz, and it can boost up to 4.4 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture.
