Wi-Fi AC with MU-MIMO: Everything you need to know

Currently home routers with Wi-Fi AC support 3 and 4 simultaneous data streams to provide higher wireless speeds, thus if we connect a client who also supports these multiple streams, we will use all the bandwidth the router allows. However, there are many devices that incorporate only one flow such as smartphones and tablets, which makes wireless network much slower affecting faster clients. With MU-MIMO technology we will optimize the overall performance of the network.

MU-MIMO (Multi-User Multiple Input Multiple Output) is a technology that is part of the standard 802.11ac and uses beamforming technology to focus the signal on wireless clients, it is also capable of allowing simultaneous transmissions to clients.

If we have a three-stream router but we connect customers that are 1-stream, wireless network instead of working at the maximum speed provided by these 3 data streams, will work at the maximum speed that one stream provides. So far, it’s logical to think the wireless network will always run at the maximum speed that the client supports, but in this scenario we connected two other clients, the best performance will be divided among the three users connected and transferring data in the network because one will transfer information first and then the other (in series).

Let’s start with the technical specifications. MSI has integrated a sixth generation Intel Core processor i7-6700HQ, high-end processor that perhaps is a bit oversized for games but MSI has wanted to play it safe so we won’t have any problems because of the processor performance.

Microsoft Edge is no match for Chrome or Firefox, at least for now

In addition to the market share of operating systems, Netmarketshare has also published data from web browsers, concluding that Internet Explorer still leads and that Microsoft Edge is no replacement for Chrome or Firefox, at least for now.

All versions of Internet Explorer accounted for half of the market (50.86%). IE 11 is number one with 24.36 percent. It is to be expected because right now it’s the latest and most widely used browser in Windows 7 and Windows 8.1. Not surprisingly, Internet Explorer 8 is the second in Microsoft web browsers (11.64%), since it is the reference in business environments with applications and services, specifically supported in this release.

Apple iMac screens are 4K and 5K and got new processors

Apple has announced that all new iMacs will have a high-resolution Retina display, as the name “Retina” has always been quite ambiguous and it’s more a marketing concept that something concrete that denotes some special feature, we will talking about its resolution, which is true 4K (4,096 x 2,340 pixels) for the 21.5-inch iMac model and 5K for all 27-inch models.


We also found there the new Intel Core Skylake processors with expandable 8GB DDR3 memory, and the graphics AMD Radeon R9 M380, M390 and the M395X in the 27-inch models, while the 21.5-inch remains in the fifth generation. Now all iMac will have two Thunderbolt 2 ports (unfortunately no Thunderbolt 3) and WiFi 802.11ac.

Asus ROG PG278Q 27″ WQHD 2560×1440 144Hz 1ms Gaming Monitor User Review

The Asus PG278Q definitely is the best monitor that you can get for your money as a gamer.

The facto this has 4 reasons:

-> The resolution 2560×1440 provides 70% more than FHD and is appropriate for the 27”size. But it isn’t as ridicules as 4K resolution that cannot be used for gaming with the current graphics card generation, even in SLI.

-> 120/144HZ. Not only during longer gaming sessions, but also in the daily PC work (Coding, Office, …) the image with 120/144HZ acts subjectively quieter and more pleasant than with 60HZ. Anyone who has savored the added value can’t go back.

Netgear Nighthawk X8 AC5300, a router to have a Wi-Fi network of up to 5.3 Gbps

Routers are those devices that the ISP technician installs at your home to settle your ADSL or fiber line that you would never concern yourself with, at least if it is a small house, because if it’s a big house or a villa, the chances of having problems with the Wi-Fi are much higher.

That’s why for these situations it’s better to use better routers such as the NETGEAR Nighthawk X8 AC5300 Smart WiFi.

AMD launches its Radeon R7 DDR4 Ram modules for Intel CPUs

Advanced Micro Devices (AMD) has started to sell their first Radeon DDR4 memory modules. The new DIMMs are not compatible with existing AMD platforms, but they can work with Intel CPUs, as well as the upcoming AMD chips that will be released around 2016.

Radeon R7

The AMD Radeon R7 DDR4 memory modules are available in 8GB capacity kits in a dual-channel setting (2 x 4GB) qualified to operate at a frequency of 2133 MHz or 2400 MHz with CL15 latencies. It is unclear whether the modules feature the Intel XMP [Extreme Memory Profiles] technology, but definitely support AMD’s own memory profiles.
