FSB on AMD Athlon 64 3000+
Hi all,
I'm looking at the AMD Athlon 64 3000+ for my next PC. I have heard that AMD's win in the gaming sector, which is what this system would be for, as I have my New Laptop and Desktop (See Sig.) for other multimedia uses. My 2 questions a 1) The FSBs on P4s are apparently quad pumped...meaning that a 400MHz FSB shows as 100MHz. Is this the case with the AMD chips? The FSB on the chip I am looking at says 400MHz, but I have also read that Athlons have upto a 2GHz FSB? That's what got me confused...so any lights in the fog would be appreciated. :-) 2) Would I notice a difference between my current P4 Desktop, and this new rig? Specs for new PC: AMD Athlon 64 3000+ (I think it's a Barton core? 512KB L2?) @ 2.0/2.1GHz 512MB DDR 3200 400MHz RAM 80GB HDD 256MB XFX GeForce5500 (To be taken from Desktop...Til' I get new Gfx.) Stock 300w PSU (Is this OK for now?) Thanks, Neil -- Desktop = P4 Northwood @ 2.6GHz, 512MB PC2100, 120GB HD, 256MB XFX GeForce5500, Stock 350w PSU Oldest Laptop = 486 @ 75MHz, 20MB RAM, 1.4GB HD, Unknown Integrated Graphics Old Laptop = P3 Coppermine @ 600MHz, 192 PC100, 12GB HD, ATi Rage Pro 4MB New Laptop = PM Dothan @ 1.6GHz, 512 PC2700, 80GB HD, 64MB ATi Mobility Radeon 9200 All still in use! |

Stock 300w PSU (Is this OK for now?) Thanks, Neil 1) The memory bus is 200Mhz with DDR400 DRAM. The 2Ghz is wrong. The hypertransport bus that connects to the chipset runs, on the latest models, at 1 megatransactions per second and is 16bits wide giving *2GB/sec*. 2) Hard to say. The Athlon 64 would be less of a bottleneck for a future graphics card. Barton is an Athlon *XP* core. The Athlon *64* cores with 512KB L2 are Newcastle, Winchester and Venice. -- Derek |

That's what got me confused...so any lights in the fog would be appreciated. :-) Yes, the P4's are quad data rate (QDR), so a 100MHz FSB gives it a 400Mbps data rate per line (not MHz even though that's what they call it). All IO goes over the FSB on the P4. The A64's FSB is double data rate (DDR), but also has a seperate memory bus so memory data has it's own seperate bus direct to the cpu core which makes access to it quite a bit faster. All other IO still goes over the FSB to the chipset northbridge but no longer has to compete with memory accesses which gives it faster access also. With the memory gone, it's really not very critical speed wise any more, but it is still a lot faster than previous FSB technology. It uses a serial HT link which can be clocked as high as 1000MHz and uses DDR. For info on the new HT technology read this. http://www.hypertransport.org/consortium/cons_faqs.cfm 2) Would I notice a difference between my current P4 Desktop, and this new rig? Depends on what you are doing. You can find benchmarks all over the place to compare the speed. Specs for new PC: AMD Athlon 64 3000+ (I think it's a Barton core? 512KB L2?) @ 2.0/2.1GHz Bartons are K7's, not K8 cores. 512MB DDR 3200 400MHz RAM 80GB HDD 256MB XFX GeForce5500 (To be taken from Desktop...Til' I get new Gfx.)

Warning "Results not Typical"
Don't even think of using his recommended $20 junk power supply despite his antidotes on how good they are for him. "Use Common Sense" a $20 600w is like saying a Brand new car 400hp only $5000 and equal to similar rated cars with 400hp like a Viper but what you get is golf cart disguised as a car with a big sticker claiming 400hp, if you pop the hood its a lawn mower motor. Read the links attached before choosing a PS. The Truth About Power Supplies is, Most all look the same although some of them come in eye candy cases designed to blind buyers common sense and prevent questions of quality. Most boast unattainable claims of wattage ratings to increase sales by unsophisticated buyers. The power supply is the foundation of your PC it does not get as much consideration as the dazzling parts such as the CPU MHz, Drive speed, gobs of memory. But the power supply is the most important part of your system so when it's time to buy a power supply it is essential that you know the difference between a good or great power supply and one that is marginally adequate or overrated and $20 600w. Most buyers tend to overlook the importance of the power supply, but these buyers are declining with the spread of knowledge on the net. Your power supply is more than just a box with wires that you plug into a wall. Now that machines are becoming more extreme or fast they demand increasing amounts of "quality reliable power" (not $18 ones) buyers can no longer ignore the importance your power supply plays in your systems reliability. http://compreviews.about.com/cs/case.../aabybpsus.htm http://www.silentpcreview.com/article28-page1.html http://www.amdboard.com/psu.html http://www4.tomshardware.com/column/20011012/index.html http://www.tomshardware.com/howto/20041223/index.html http://www.tomshardware.com/howto/20040122/index.html http://www.firingsquad.com/guides/power_supply/ Make sure your supply has Certified compliant for AMDT and Intel® ATX 12V Over Voltage Protection Under Voltage Protection Over Load Protection Over Current Protection Over Temperature Protection Short Circuit Protection Detective sensor output Low Noise & Ripple Hi-pot tested Certified EMI Approvals: FCC, UL, CUL, CSA, CE (Minimum) "Wes Newell" wrote in message newsan.2005.04.23.05.22.28.712249@TAKEOUTverizon .net...

I don't think you'll find many (if any) 300W PSU's with anough current to even boot a K8 system. AMD tech support recommended a minimum of 475W.
