Ik zag bij JC nog meer info ver de K7 presentatie van gisteren. De info hieronder zul je deels al zijn tegengekomen in een nieuwsposting eerder vandaag. Echter ook een aantal nieuwtjes die denk ik wel interessant zijn:
hi,
I've just returned the dinner meeting at which Dirk Meyer (VP of Eng.
AMD) had a presentation. My first impression is that K7 looks very promising.
Mr. Meyer told us that AMD was indeed announcing K7 this month (June
'99) at 500, 550 and 600 Mhz. It has 22 Million transistors on a 184
mm square die at .25 micron process.
The first release of K7 will have 512K of L2 cache at half-speed.
At 600 MHz, K7 is %115 faster in SpecInt95 than a PIII Xeon 550Mhz
with 512K full speed cache. At 550 K7 is %106 faster in SpecInt.
At 600MHz, K7 is %143 faster than the same PIII Xeon at SpecFPBase.
At 550Mhz, K7 is %136 faster (these numbers are interpolated visually
from a slide which means 143 was closer to 140 than 150).
At 3D Winbench 99 V1.2 (null driver) on win98, K7 600 is at %146
faster than the said PIII Xeon using SSE optimizations.
There are new Integer SIMD instructions, DSP type instructions for
MP3, AC (audio) etc. and cache prefetch instructions. Microsoft will
support 3DNow in an upcoming Visual Studio release.
At the initial launch, there won't be any MP systems. All motherboards
(from Asus, Biostar, Gigabyte, FIC and one other I couldn't catch)
will use AMD chipset. Via, ALI and SIS are designing their own
chipsets to be released before the end of this year.
These are most of my notes during the one hour presentation and Q&A
afterwards. All errors are my own. I speak only for myself etc., etc.
muzo
Update: AMD Zone heeft nog meer info bijeen geraapt in dit handige artikel.
