The Best CPUs of 1H 2017 (DRAFT)

Hey everyone.Recently, Tom's Hardware updated their CPU recommendation list for the second quarter of 2017.If the link changes or gets broken, what Tom's recommended is:Pentium G4560Core i3-7100Core i5-7500Core i5-7600KCore i7-7700KThe problem with this list has to do more with the title than it does the actual recommendations. The list is designed for future PC gamers to quickly choose a processor without having to sort through many benchmarks, so the criteria used in selecting these CPUs is only gaming benchmarks. The title, "Best CPUs", gives an impression that the... read more

EVGA Hadron Air Chassis - Tips & Compatibility Guide

Quote:"Why sacrifice appearance and size when choosing a performance rig? The EVGA Hadron Mini ITX chassis was designed to not make any compromises." - Hadron Air manual The Hadron's appearance and size are the main reasons owners decide on this chassis, however it's not without some compromises. As long as you are aware of what limitations the case has, and plan your parts around it, you shouldn't run into many problems. Your choice of components is primarily limited by size. It was worth doing the extra research to find the appropriate parts, but it wasn't easy.... read more

Analyzing the Source Code of UEFI for Intel Galileo by PVS-Studio

Firmware development, even when done not in assembler for exotic architectures but in plain C for i386/amd64, is a pretty tough job, where a single bug can cost too much - up to a major failure of the target hardware platform. So it is just vitally necessary to use various techniques to avoid errors at the earliest firmware development stages.Unfortunately, we can only dream of formal verification or application of MISRA C in case of UEFI firmwares (on the other hand, no one feels like spending a couple of years and 50% of the project budget on firmware development),... read more

DIY: How to do a fiber optic mechanical splicing: steps and tips

Mechanical splicing is the process of precisely aligning two fiber optics together using an alignment device and index matching gel that has a similar refractive index and covers the possible air gaps, helping light travel from one fiber to another with minimal loss and little back reflection. However, they are still two separate optical fibers, which is why this method is considered temporary and is mostly use to rapidly restore short-haul single mode or multimode cables in FTTH installations. How to do it? Mechanical splicing is easy to do if you have all the tools... read more

Intel Core i7 4790K Energy Efficiency

Introduction During the time of the first generation Intel Core i series, Tom's Hardware made an article about finding the most efficient clock speed for Core i5 750 http://www.tomshardware.com/reviews/core-i5-750-efficiency,2500.html and Core i7 920 http://www.tomshardware.com/reviews/overclock-core-i7,2268.html. I got curious as to what is the most efficient clock speed for my Core i7 4790K. Test System [CPU] Intel Core i7 4790K [GPU] Gigabyte GTX 970 mini-ITX [MOB] Gigabyte Z97-D3H (F7 bios) [RAM] G.

Intel Hyper Threading - Performance Scaling with CPU Frequency

Test System [CPU] Intel Core i7 4790K [GPU] Gigabyte GTX 970 mini-ITX [MOB] Gigabyte Z97-D3H (F7 bios) [RAM] G. Skill Trident X 4GBx2 DDR3 @ 2400 MHz 10-12-12-31 2T [HSF] Noctua NH-U12S Windows 7 64-bit with Service Pack 1 GeForce 355.82 Test Methodology For productivity testing, I only used HandBrake. The short movie (about 10 minutes long) Big Buck Bunny was encoded from AVI to MP4 using High Profile preset. Video resolution is 1080p. Only the first 2 minutes of the video was encoded to shorten the benchmarking time. Big Buck Bunny is an open movie which was... read more
