Of course, an inexperienced reader may not understand what is the irony here and why, in fact, distinguish between pseudo-quad-core processors and genuine quad-core processors.
"Phenom II is a big step up, too, but you don't have to open your wallet as wide to make that step up," Taylor said.At one of Intel's press conferences, when asked when it will finally start producing genuine rather than pseudo-quad-core processors, an Intel spokesman replied that genuine processors are those sold in stores, and not those that exist only in the imagination of marketers AMD. But AMD might just be about to drop some surprisingly powerful processors on the market as well. Intel is hitting first with what it calls the "fastest processor on the planet" (with a lot of shared enthusiasm from reviewers, we should add) and the new Core i7 parts are, without a doubt, a major step-up in performance over the older Core 2 Quad chips. But now that both Intel and AMD are really hitting their stride on successive generations of quad-core architectures, the new chips are coming out of the gate pretty darn fast. So who said the clockspeed battles are over? Over the past few years, we've heard quite a lot about how it's not as important on multicore chips. It'll be the biggest step in processor improvement between generations that AMD has ever made, with the exception of leading the industry from single to dual-core." "The result has been modest improvements on instruction per clock but much better clock frequency. So you've got higher clock frequency per TDP, but at the same thermals," he said. "It's about high-speed path optimizations, how it does memory pre-fetch, how it does branch predictions, the larger cache. Taylor said the extra level of "headroom" towards dramatic overclocking capacities on the Phenom II parts is due to a combination of architectural improvements over the original Phenoms first released late in 2007. Taylor said the processors shown were not hand-picked engineering parts, though he added, "But clearly they weren't duds."Ĭlock speeds for AMD's upcoming 45nm desktop chips appear to be mapping to the same sort of advantages the recently released 45nm Opterons code-named Shanghai have displayed over the previous generation of 65nm Barcelona server chips.

Some enthusiasts have also taken Core i7s to 5.7GHz on liquid nitrogen, while the CRN Test Center conducted some "modest overclocking" on the Core i7-965 Extreme Edition to add some extra oomph to an already astonishing Geekbench2 score for that processor on an Intel "SmackOver" board.ĪMD's Taylor said the Phenom II demos conducted Thursday were done on what the chip maker is calling its "Dragon" platform - a quad-core Phenom II processor, ATI Radeon 4800 series discrete graphics and an AMD 790 chipset. Overclockers have reportedly managed to scale it to 4.5 GHz on air cooling alone. Intel's top Core i7 processor, which incorporates the Santa Clara, Calif.-based chip giant's new Nehalem micro-architecture, is listed as a 3.2 GHz part. The top Phenom II chip, due out sometime in the first quarter of 2009, will reportedly list as 3.0 GHz off the shelf.

Respecting AMD's wishes, we'll just point out that PC Perspective's story now says, "The Phenom II reached WELL over 5.x GHz (read: REALLY over)." And another source gives a more specific number - 6.3GHz, though again, that could not be confirmed by AMD.ĪMD, headquartered in Sunnyvale, Calif., reached such overclocking heights using liquid nitrogen to cool the processor that was taken to "WELL over 5.x GHz." PC Perspective reports that the Phenom II parts can also hit 4 GHz on air cooling and 5 GHz on dry ice cooling. How far north of 6 GHz? AMD spokesman John Taylor confirmed the basics of stories published by PC Perspective's Josh Walrath and Legit Review's Nathan Kirsch Thursday, but held back on outright endorsing the numbers originally cited in those stories. Advanced Micro Devices demoed its upcoming 45-nanometer "Deneb" desktop chips - now confirmed as Phenom II - for reviewers in Austin, Texas, on Thursday, and reports are in that AMD overclockers were able to achieve clock speeds north of 6 GHz on the second-generation quad-core devices.
