The Core i7-4770K is Intel's fourth generation (codename Haswell) flagship processor in the hugely successful Core range. It's not surprising that the 4770K sets a new Real World Performance index record, besting its predecessor by just over 9%. The 4770K also tops out in the remainder of our benchmarks setting new highs of 10020 and 2164 in the PassMark and PassMark Single Thread tests which equates to roughly an 8% overall performance increase over the 3770K. With a TDP of 84 watts, power consumption has increased slightly over the 3770K. The new Core i7-4770K demonstrates around an 8% performance increase over its predecessor the 3770K but it costs 12% more. As a result, at least until prices drop, this processor represents marginally worse value for money than the 3770K. [Jun '13CPUPro]
The 8 core, 16 thread 1900X is the third and entry-level processor from AMD’s Threadripper series of high-end desktop (HEDT) processors. The 1900X is based on AMD’s 14nm Zen architecture and features 20MB of cache (16MB of which is L3) and quad channel DDR4, which is twice as many channels as in the Ryzen 7 series. It has a base clock of 3.8GHz increasing to a boost of 4.0 GHz and has an additional short-term boost of 0.2 GHz when thermals allow. Most impressively, the 1900X features 64 PCIe lanes which is the same of number of lanes in the nearly twice as expensive Ryzen Threadripper flagship, the 1950X. This facilitates the simultaneous high speed PCIe connection of up to seven different graphics or storage peripherals. By comparison, Intel’s similarly priced 8 core, 16 thread i7-7820X which, even though it has an 11% effective speed advantage over the 1900X, only has 28 PCIe lanes (down from 44 lanes as recently seen in the recent i9-7900X). Both upgrade options may require new, and not inexpensive motherboards, the 7820X requires an X299 (Basin Falls) chipset and the 1900X utilizes the premium X399 motherboard. Despite the considerable price tags attached to the CPUs and motherboards, never before has HEDT processing been so affordable. [Oct '17CPUPro]
