Thoroughbred Overclock

[Bozo Galora]

* AMD 0.13u Thoroughbred 1800+
* (AXDA1800DUT3C AIPCA0208TPBW)
* Default VCore 1.6V
* CPUID 0680
* 266Mhz FSB

EPoX 8K3A+ (24/03 Bios) and IWill XP333-R (11/04 Bios) motherboards are able to detect the Thoroughbred correctly. By setting a VCore voltage of 1.95V on the IWill XP333-R, Thoroughbred 1800+ (1.533Ghz) is able to overclock to 1.9Ghz air cooled while a VCore voltage of 2.15V on the EPoX 8K3A+, a max clock speed of 2Ghz is achievable. However, a clock speed of 1.9Ghz is stable passing all the benchmarks like SuperPi, Cpumark 99, SiSoft Sandra 2002, PCMark 2002 Pro and 3DMark2001.

Cool, thanks. It's nice to see they're pretty overclockable and scoring well. Awesome link!

That is good!!! I like the look of the lower vcore though it only represents a drop of .15 from the xp and tbird while the p4 drop from .18 willamette to the .13 northwood was 1.85v to 1.5v....

I wonder what kind of temps are going to be expected....

Also, I would have expected this since xp's of the 2100+ .18 micron were already doing 1.733ghz at default and many seem to get it to 1.8ghz air cooled anyways. So if the first .13 micron didn't come out and offer what's mentioned above it wouldn't bode well for AMD and the ability of this chip to ramp until hammer gets here....In that sense it will be a short lived product I guess, but it will likely need to get the xp line to the 2ghz line to stay competitive with the p4 line which should be around 2.8ghz by end of summer.


Also since the thoroughbred offers no architecture or performance enhancements, just merely a die shrink and hopefully some temperature alleviation, it should be easily to figure projected performance of thoroughbred up to 2ghz....It is likley a xp 2400-2500+ (1933-2000mhz respectively) will be needed to compete with the 2.8ghz p4's (533fsb) conservatively....


I think the thoroughbred's goal is merely to keep it close while amd tries to one up intel with the hammer....

yeah, I agree. that overclock of 20% reliable is very disappointing to me, especially in the face of painless
monster overclocks on the p4. while I'm sure a thoro doing 1.9 would keep up with/beat a 2.6 P4, its not a
"clean kill" by AMD. One cant help but be attracted to big numbers.

Look at the last page of the review. The screen shows motherboard temp of 23C and cpu temp of 49C! I'm not sure if that's in an overclocked state or not. IMHO, 1.95V is really pushing it for a cpu with 1.6V default. I would like to see what the Tbred can do with a more normal 10-15% voltage increase. My guess is, it won't do much better than the current XPs.

 

[Swanny]

Oh well. At least we know the CPU is working fine and ready for shipping.

that temp reading is @1.58V CPU VCore.

Who knows what the clock speed is.... Either way, considering the cooling method, it doesn't look like tbred is any cooler from a socket-thermistor perspective (and probably not from an internal temp perspective either.

AT brings another site to its knees.

TBred is a big disappointment so far. I will wait for Barton and hope AMD releases them at 166 MHz FSB so I don't have to unlock it...
