Radeon HD 6620G IGP 

Released December, 2011
  • 444 MHz

The NVIDIA G-Sync technology is a revolution for PC gamers and three of the gaming industry’s greatest developers of all time, ID ‘John Carmack’, DICE ‘John Andersson’ and Epic Games ‘Mark Rein’ support the technology and came on stage to talk about the new G-Sync technology and how it would help alleviate PC gaming.

My short time with the NVIDIA G-Sync prototype display has been truly impressive, and getting some play time in with Battlefield 4, Crysis 3, Bioshock Infinite and even some good old Battlefield 3 was awesome.

Phanteks Glacier G1080 Water Block

The G1080 also features RGB LED lighting that can sync with Phanteks cases that supports RGB lighting or motherboards’ RGB software by using our Phanteks RGB adapter.
The G1080 uses military class Viton O-ring compared to silicone O-rings used by other manufacturers, well known for its excellent heat resistance and its durability.
As for UWP's continued evolution, the blog post does tease that we should "expect to see some exciting developments on multiple GPUs in DirectX 12 in the near future.
For G-Sync and FreeSync users, the ability to draw to the screen at any range of render rates will offer an even further advantage of uncapped frame rates, no tearing but also, no "dropped" frames caused by running at off-ratios of a standard monitor's refresh rate.

Dissecting G-Sync and FreeSync - How the Technologies Differ

by Ryan Shrout |
If your game is rendering at 40 FPS, lower than the minimum VRR window, then you will again see the result of tearing (with VSync off) or the potential for stutter and hitching (with VSync on).
But, this method requires a local frame buffer and requires logic on the display controller to work.
From a design perspective, the G6020 is aimed at very simple desktop workloads – the Android UI, wearable interfaces, etc..
