Product Information

Specifications and connection of peripherals supported by Core i7-4790K and Core i7-4790S. PCIe version Processors that support 64-bit computing on Intel® architecture require an Intel 64 architecture-enabled BIOS.

When the 4790S does use less power, however, we saw a drop in temperature of up to about 5 °C. This isn't insignificant, but at the same time is not going to be a game changer in most situations. See http://www.intel.com/content/www/us/en/architecture-and-technology/hyper-threading/hyper-threading-technology.html?wapkw=hyper+threading for more information including details on which processors support Intel® HT Technology.

Performance: On applications that can only utilize a few threads, the S-series CPUs are essentially identical in performance to their standard counterparts. If an application can use a higher number of CPU threads (or if many applications are running at once), however, the S-series CPUs can be as much as 5% slower than the standard models.

Intel® Transactional Synchronization Extensions

First, the S-series CPUs have a much lower base frequency than the standard CPUs. You would think this means that they will always be slower, but we've shown in the past that the base frequency is somewhat of a meaningless specification due to Intel's Turbo Boost and Speedstep technologies. These technologies mean that an Intel CPU will only rarely operate at the advertised base frequency which brings into question whether this spec actually has any bearing on real-world performance.

Otherwise, use the Intel® UHD brand. As we pointed out earlier in this article, due to Intel's Turbo Boost technology an Intel CPU will almost always operate above its rated base frequency when put under load. What is often overlooked, however, is that the Turbo Boost frequency at which a CPU runs depends on the number of cores actively being used. In fact, the maximum Turbo Boost frequency Intel lists on their specification sheets only applies if the CPU is using just a single core. As increasingly more cores are used simultaneously, the maximum Turbo Boost frequency is reduced. To compare the official specifications between S-series CPUs and their standard counterparts we took four of the latest generation Haswell CPUs. There are, of course, more models available from Intel, but we've found that the differences between S-series and their standard counterparts to actually be very consistent, so this is a good representation of the S-series as a whole.
