New PowerPC Chip Faster Than Intel’s Best?

May 22, 2007

“Ah, if only Apple would’ve stuck with PowerPC, maybe it could’ve skipped the magical 3GHz mark and jumped straight to 4.7GHz. Okay, that’s really just a cheap shot, but I couldn’t resist, given today’s major announcement by IBM that the 65nm POWER6 will not only debut next month at a stratospheric 4.7GHz, but it also shreds most of the relevant benchmarks. But before we get into the details, let’s take a look at the basics of what was announced. From IBM’s press kit, shorn of some of the marketspeak and with some of the details expanded:

  • Top frequency of 4.7GHz
  • >790 million transistors
  • 341mm2 die size
  • 65nm SOI process with ten layers of copper interconnect and a low-k dielectric on the first eight levels
  • Dual-core
  • Two-way simultaneous multithreading (SMT) on each core
  • Two memory controllers
  • Manufactured at IBM’s 300mm semiconductor fab at East Fishkill, NY”

8 Cores Supported In Unreal Engine 3

May 17, 2007

Bring on Unreal Tournament 3!

“Are you from the future? Got an 8-core CPU? The Unreal Engine 3 has you covered, says Tim Sweeney:

AMD’s new quad-core technology should provide a great performance boost for today’s high-end PC games,” said Tim Sweeney, founder of Epic Games Inc. “Our Unreal Engine 3 game technology can take advantage of four and even eight processor cores, improving performance by accelerating physics and AI calculations, and increasing the realism of the game environments our artists can build. Upcoming games like Unreal Tournament 3 will truly fly on these new CPUs.”

AMD On Track For Summer Launch Of Barcelona Quad-Core

May 3, 2007

Get ready to build your next PC – The Quadfather

As Advanced Micro Devices moves closer to the summer launch of Barcelona, one thing is clear with analysts: the highly anticipated quad-core microprocessor alone won’t be AMD’s weapon of mass destruction against Intel.Instead, Barcelona, the next generation of AMD’s Opteron processor for workstations and servers, is expected to buy AMD a bit of time with a short-lived performance boost against its larger rival.

“Barcelona should put AMD back in the race, if not in the lead, in the server market,” Jim McGregor, analyst for In-Stat, said. “But this by no means is a complete cure for AMD.””

Intel To Introduce Penryn Chips in 2007

March 29, 2007

Some of these features seem very good.

“The Penryn chip will also have better power management than previous Intel processors, with deeper sleep states than Core 2 Duo chips. Thanks to that efficiency, Intel plans to run its new chips faster than 3GHz for desktop and notebook versions, reversing an industry trend of scaling back the processor speed in order to add more cores without creating too much heat.”

“In other improvements, Intel will use 50 percent more on-chip memory in Penryn chips than Core 2 Duo, allowing them to hold more data on the chip instead of spending time and energy retrieving it from the PC’s main memory bank. Dual-core Penryn chips will have 6M bytes of L2 cache while quad-core versions have 12M bytes. Intel said it also will speed Penryn front side bus speeds to 1600MHz, instead of the 1066MHz or 1333MHz options now available, granting up to a 45 percent improvement for high-performance computing applications like computational fluid dynamics.”
