So for a new system which may be serving me for a long time into the foreseeable future (old system is many generations obsolete). I've narrowed my choice of CPU to two candidates: i7-7700K and i5-7600K.
My goal is a combination of maximum single thread performance and some decent level of multi-core performance without going far past $300. The i5-7600K would essentially function as saving a nice chunk of $ should I decide HT isn't worth it (especially if they can achieve similar clockrates). I suspect HT may bring more potential problems than it does potential performance.
1. How would the top-end long-term sustainable 24/7 overclocks compare for the 7700K and 7600K? Overclocking on air with a relatively powerful HSF combo, but no ultra-loud fans (moderately noisy is fine, example: under-volted high speed Delta tri-blade 120x38mm fans). I'm expecting ambient room temps in the 79°-81° F range typically, with reasonably good case flow (less powerful than the CPU fans).
2. Is the IHS likely to be a problem for maintaining any decent OC, perhaps over the long term? I've read many remarks about how bad the IHS can be on these things. I don't want to deal with de-lidding for the foreseeable future.
3. Does HT tend to significantly limit OC results?
4. How does HT overhead and HT enabling/disabling work? Some questions:
- Can HT only be enabled/disabled on all cores at the same time, or can it be enabled/disabled on an individual core basis?
- Can HT be toggled on the fly or does it require a reboot?
- Does HT overhead only apply when HT is being used on a specific core, or is there always overhead on all cores merely by virtue of HT being enabled?
- Can HT overhead be avoided on one core that's being used for a single thread app, but enabled on the other cores?
5. Can HT realistically provide more than a 15-19% potential performance boost to multi-thread processing? Are there any real world analogues to the 48% synthetics?
6. What benefits and problems have you experienced thanks to HT on any recent Intel quad+ core?
7. Are there any comparable CPU models I may be neglecting to consider for purchase? I've thought of, as an example, the Skylake analogues to these two models. I figured these newer ones would offer some better future-proofing on a platform/features level, but then again, maybe there is a better/cheaper selection of motherboards for the older ones. I will be investigating motherboards and RAM soon.
