The 4770k didn't support VT-d, whereas the 4790k did. The 7700k has a much faster bus speed, and supports up to 64 GB of DDR4 memory.
I know these are small changes, but they make a difference. For instance, I have a 4790K because I wanted IOMMU (VT-d). I wanted an ITX build, but I went with micro-atx because I needed 4 dimms of ram to reach 32 GB. With a 7700k I could have an ITX build with IOMMU and 32 GB of ram.
Here's the ARK comparison: https://ark.intel.com/compare/75123,80807,97129 https://ark.intel.com/compare/75123,80807,97129
I don't know if the 7700k actually supports VT-d, but I would guess it does. I wouldn't actually buy one until I knew it supported VT-d though.
- dx034 10y agoA question as I'm not that familiar with the Intel terminology: What does it mean that they dropped the "SmartCache"? Is the newer cache not smart anymore or did it just become standard? Or is Smart actually worse?
- Declanomous 10y agoI don't think they actually dropped SmartCache. SmartCache is just a way of saying that all of the cores share the same cache space. (Generally, the cache is divided equally among each core for multi-core processors.) The Kaby Lake architecture is basically the same as the Devil's Canyon architecture with some minor tweaks, so there is basically no chance they changed how caching works, as that would be a really major change. Chances are the person in charge of adding information to ARK doesn't have the ability to release or verify all of the info yet.
