| i7 7820X is the CPU is probably the best system price/performance overall in the long run right now. Threadripper might be competing it depending on what you do but we don't know about it yet. For software developers having over 50% lead in compilation performance compared to ryzen 7 1800X (nightly build of chromium on visual studio) should make it a good choice. A) In system price there are many components and that
makes ultra cheap CPU:s in other vice identical configurations not so good price-performance. B) Performance is really the performance differential from what you upgrade. And even more importantly the performance differential years from now to systems of that time, if you upgrade to a system that lasts 5 years before you upgrade or to a system that lasts 7 years before you upgrade is significant in terms of price/performance because later means you get the high performance early and price last longer. C) Significantly higher single threaded performance compared to Ryzen 7 the main contender. There are still many tasks that are single threaded, especially if you run legacy code. D) AVX-512 I doubt the review benchmarks are in AVX-512 but some legacy code. AVX-512 increases both width of vector and fraction of code and algorithms that can be parallerized significantly. Once compilers are well tuned to use AVX-512 the code compiled with AVX-512 optimizations turned on should be significantly faster than what it was before hand. Simply being able to do 8-16 times work per cycle in large variety of tasks is significant advantage even if that is for a good fraction of time instead of all the time. Personally I7-920 has given me far better price-performance compared to people who bought dual core at the time simply because it has lasted LONGER so it had superior price/(time between CPU upgrades) measurement. Right now in that same measurement I7-7820X is the king. So in conclusion I7-7820X is faster in both real legacy code and the future code, and gives good enough performance longer simply because code that you run when you would start considering upgrades run much faster on it simply because of extensions. |
