Haswell’s Refresh has already laid the foundation for an influential desktop’s PC with the Core i7-4790K and 297 motherboards. And now, folks want the fastest Intel rig that have been building with the six-core core i7-4930K and Core i7-4960X LGA 2011 chips from last September’s Ivy Bridge-E range, which brag massive 12MB and 15MB L3 caches and support for quad-channel DDR3-1866 memory.
Intel’s Extreme Edition processor line is very old now. It started off back in 2003 with a single-core Pentium 4EE3.4GHz, shared the same socket 478 platform as standard Pentium 4 processor but received an exclusive L3 cache. It comprised of 169 million transistors on the 130nm process and priced in line with what it might have cost to build up an entire PC, the Pentium 4 EE was a stern business.
Now, take a look at the three new processors: the Core i7-5820K, Core i7-5930K and the Core i7-5960X. 5820K was priced at $389; Core i7-5930K priced more than $583. An important thing to note is that there are available PCI Express 3.0 lanes which increase from 28 to 40 lanes. The Core i7-5820 offers 12 more lanes than the Core i7-4970.
The Core i7-5960X is the Extreme Edition version and is a considerable upgrade from the Core i7-5930K. Where the PCIe 3.0 lanes remain at 40, users will get 33% more cache at 20 MB, the core count increases from six to eight and with the help of Hyper-Threading that means 16 threads are supported. It is priced at $1,050 and it is clocked as the lowest out of the three at just 3.0GHz with a maximum Turbo frequency of 3.5GHz. That implies 5960X is slower than the Core i7-4960X when using six or less cores as the 4960X is clocked 20% higher. Something worth keeping in mind is that the Core i7-5960X doesn’t come with any kind of cooling. Intel has recommended liquid cooling and their TS13X solution that will cost around $100.
