Top single-core performance.
Top single-core performance.
Looking for the top single-thread performance now. You're aiming for a CPU with at least eight cores, capable of handling 8x EDA CAD simulations smoothly. Overclocking isn't an option, so focus on high base performance and stable 5GHz operation across all eight cores. The 9900K offers strong IPC and solid max speeds, paired with the best memory support available. AMD options in this range are limited, but the Intel 9900K remains a strong contender. Double-check your requirements for dual-channel configuration and ensure the memory matches its bandwidth.
9900ks seems to be a strong option, though other programs like AMD might perform better, and some could run more smoothly on a 9990x with enhanced caching and AVX support.
The 9900KS performs less efficiently compared to the 9900K due to fixes for Intel flaws. For top speed, go with the 9900K and add strong cooling if needed. Available pre-binned 9900K chips are also available.
The goal is to execute 8 independent jobs simultaneously using as little time as possible. The EDA CAD Linux software runs efficiently without IO constraints, though performance depends on memory bandwidth versus a quad-channel setup. It’s likely CPU-bound, so hardware testing might be necessary. We should compare Intel dual-channel (9900ks) against AMD's equivalent in a quad channel configuration, keeping cost in mind—avoiding extremely expensive Xeons.
I’ve seen the spec that the 9900k only supports 5GHz on two cores at once.
The only quad channel chip available in your budget is a thread ripper. However, these won't share the same clock speed. Still, the RAM bandwidth and cache might compensate for the lower GHz. It's tough to be certain, I'm just making an educated guess about the software requirements.
The program works with both 32 and 64-bit versions (it’s not limited to one size). Each thread simulation uses less than 4 gigabytes of memory, which means 32-bit executables are sufficient. On today’s hardware, switching between 32 and 64-bit doesn’t noticeably speed things up. The choice between dual-channel and quad-channel setups, along with variations in IPC and click rates between Intel and AMD, adds complexity to the decision. That’s why I’m seeking your input.
