AMD 'Venice' Core Shows Big Drop in Power Needs
dtjohnson writes " Lost Circuits has carefully measured the power consumption of four recent Athlon 64 cores and has found that power consumption has been dramatically reduced in the new 'Venice' core from the relatively-low (compared to Intel P4) numbers of the original 2003 'Clawhammer' core to less than 30 watts under load and less than 10 watts for Windows at idle. This huge power reduction was apparently accomplished by a combination of 90 nm die shrink, Silicon-on-Insulator technology, and something called 'dual-stress liner technology' As Lost Circuits points out, power consumption worldwide has been exploding as more CPUs come online and the CPU power requirements increase so a significant power reduction will reduce the burden on electrical grids everywhere." -
Previewing ATi's Radeon X800 XT & X800 Pro
Giant_Panda writes "A few short weeks ago, it looked like NVIDIA was back on track as they were able to overtake ATi and reclaim the 3D performance crown with their GeForce 6800 Ultra. Now, it seems like ATi has fired back with a killer card of their own. HotHardware just posted a preview of the new 12-Pipe ATi Radeon X800 Pro ($399) and 16-pipe ATi Radeon X800 XT ($499). The X800 XT seems to be faster then even the new GeForce 6800 Ultra Extreme cards that were rumored to exist on a few sites this past weekend and the X800 Pro is a great performer as well. (Other sites have just posted previews: TechReport, Hexus, Lost Circuits)" -
HP Shows Off PA-8800 SMP-On-A-Chip CPU Plans
Eric^2 writes: "At last week's MicroProcessor Forum, HP's David J. C. Johnson unveiled the details of HP's latest RISC processor destined to redefine performance in Server-Class processors. Following a relatively simple strategy, the PA-8800 processor combines two PA-8700 cores on a single chip to enable symmetric multiprocessing (SMP) on a single processor. Aside from bumping the core speed up to an initial 1 GHz, enhancements include the addition of combined 35 MB L1+L2 cache. The article contains the full text. AMD, please steal an idea..." -
NEC Signs Rambus Royalty Agreement
Zarquon writes: "NEC has agreed to pay licensing fees and royalties to Rambus for production of SDRAM, according to this TechWeb article. They're the fourth company to give in to Rambus; Hitachi, Toshiba, and Oki have already been signed to similar agreements. If you're unfamiliar with the Rambus patent fiasco, LostCircuits has a good synopsis of the situation." Ah, yes -- beat them in the courtroom, not the marketplace. -
