I'm checking the value of expenses for an Xeon build using the LGA 3647 socket, but I'm unsure if it offers significant advantages. For example, when considering the i9 11900K, the justification usually comes from performance gains of the 11th generation CPU over the 14th in similar workloads.
Early 12th generation CPUs are also viable choices since the initial production models supported AVX-512 unlock. You'd need to turn off the E cores and use a BIOS version that allows it, which most motherboards do have. Whether this compensates for the gap depends on how the feature is implemented; generally, an AVX-512 enabled 12900K with E cores disabled will perform similarly to a fully enabled 14900K, just slightly slower. This varies based on the setup and workload usage. The 11900K seems less practical because most AVX-512 tasks also demand high memory bandwidth, making DDR5 a strong contender. Also, the Ryzen 7000 line with AVX-512 support offers lower power use and comparable performance to the 14900K on similar chips like the 7950X.
Relies on the particular software and processing demands. I’m unsure if a 11900k will outperform a 14900k. Could you share specific applications you’re interested in? Also, consider the Ryzen 7000 for better efficiency.
We're a software developer looking to use Intel's DPC++ compiler, Intel MKL, and other Intel proprietary tools for simulation software. I can't rely on AMD due to compatibility concerns. I'm not interested in risking my budget. For public options, ffmpeg and davinci resolve are available.
I think it makes sense to start with an older 11th gen model and then move to a newer one. Avoid the 11900k since it's closer to 11700k but offers only a slight boost for significantly more value. The 10900k performs better in multi-core tasks due to its dual-core capability, while single-core results are similar. Both are now relatively affordable used options, though they’re considered average in quality. Check out the LGA4677 line—it provides budget-friendly 6-core CPUs under $300 with AVX512 and 13th-gen architecture. It’s a great choice if you specifically need AVX512 support and want better value.
They can be used with the LGA4677 xeons, but availability varies depending on the board you select since it's a BIOS feature that must be present.
Around the 11th, I owned an i7 and found it quite disappointing, particularly with software-based av1 encoding. That’s prompting me to ask: Should I upgrade to a Core i9 14-th, or move to an Xeon space now?
