Microsoft earlier this week announced the next version of its Xbox line of gaming consoles, ahead of E3 2017, now ongoing in Los Angeles. The new Xbox One X, which goes on sale Nov. 7 for $499, is slimmer than previous models and packed with power. With a 6-teraflop Scorpio engine, the One X has 40 percent faster graphics performance than its chief rival, Sony’s PS4 Pro. The custom Scorpio engine in the Microsoft box burns chrome at 1172 MHz — a 37 percent increase over its predecessor, Xbox One, and 28 percent faster than PS4 Pro.
