AMD’s Jaguar Architecture: The CPU Powering Xbox One, PlayStation 4, Kabini & Temash

Anandtech is dicussing AMD's Jaguar architecture.  Jaguar is going to power more gaming than any other chip outside of casual phone gaming.

 

Bobcat was a turning point for AMD. The easily synthesized, low cost CPU design was found in the nearly 50 million Brazos systems AMD sold since its introduction. Jaguar improves upon Bobcat in a major way. The move to 28nm helps drive power even lower, which will finally get AMD into tablet designs with Temash. Despite being lower power, Jaguar also manages to increase performance appreciably over Bobcat. AMD claims up to a 22% increase in IPC compared to Bobcat. Combine the IPC gains with a more multi-core friendly design and Jaguar based APUs should be appreciably faster than their predecessors.

AMD Price Drops With FX-6350 and FX-4350 Introduction

CPU World has spotted AMD price cuts across most of their CPU line now that the 125 watt FX-4350 and FX-6350 have been introduced.  Older parts have gone away.

 

A handful of old Phenom II X4 and X6 microprocessors were removed from the price list, including Phenom II X4 840, 905e, 910e, Phenom II X6 1055T, 1075T, 1090T BE and 1100T BE. The only Phenom II part, that had its price revised, was X4 965 Black Edition. This CPU now costs $81, down from $91.

10 Years of x86

The Inquirer notes that Monday marked 10 years of AMD's x86 with the release of the Opteron.  

 

A DECADE AGO AMD released the first Opteron processor and with it the first 64-bit x86 processor.
AMD's lavish New York launch for the Opteron processor was far more than a product launch, it was AMD showing it could reproduce the success of the Athlon K7 chip and take the fight to Intel by developing ground breaking new features and not just one-upping its rival on some benchmarks. The firm's Opteron processor brought 64-bit computing to the commodity x86 chip market, along with an on-die memory controller and the Hypertransport bus all in one product.

AMD Centurion: 5GHz On Air At $800

Hexus reports that AMD will release the Centurion FX at 5GHz on air, and rumored to be $795 in price.  

 

So how about this as a rumour for a Friday morning? Though AMD will never go on record and confirm this, we have it on good authority that the chip-maker will soon be releasing a super-FX chip. Based on the same 'Vishera' architecture powering the current FX-8350, which runs at up to 4.2GHz, this new FX, codenamed 'Centurion', is to be made available in very limited quantities.

AMD: Moore's Law Ending?

The Inquirer reports that AMD's John Gustafson believes Moore's Law is coming to an end.

 

According to Gustafson, the transistor density afforded by a process node defines the chip's economic viability. He said, "We [AMD] want to also look for the sweet spot, because if you print too few transistors your chip will cost too much per transistor and if you put too many it will cost too much per transistor. We've been waiting for that transistion from 28nm to 20nm to happen and it's taking longer than Moore's Law would have predicted."
