AMD X2 5800+, 6000+, and 6400+? Why?

How does the AMD X2 5800+ compare to the Windsor 6000+ 6400+? Why would they make these so similer? Would the 5800+ have about the same performance of the Windsor 6000+ or 6400+? Which would be best if I wanted a cheap upgrade from a 4800?

5800+ 3.0Ghz 2x512kb 65nm 89W
6000+ 3.0Ghz 2x1mb 90nm 125W
6400+ 3.2Ghz 2x1mb 90nm 125W

I doubt you would see much of a difference between the three, the 5800+ may be a little slower because of it's reduced cache. There's also a benefit to using the 5800+, the 65nm die size means lower power usage if that's something you seek. Also, it was probably a typo but the 6400+ is 3.2ghz. There aren't any 6.0Ghz processors, the max stock speed I'm aware of is 3.33ghz.

Each series of processor, they make minor changes and improvements. It's meant to give options for customers. The changes are usually in the bus speed and the cache.

I think you meant 3.2Ghz on the 6400.

In all honesty, all of these processors are pretty low end. Are you looking to put something together? If you are interested in mid range cpu's, you may want to look at intel. AMD went by the wayside for the last several years. I would put the similar priced e5200 over the three you've listed.

I did mean 3.2Ghz, thanks.

Will the smaller die size make up for the smaller cache?

I was planning to upgrade the 4800+ to a 6000+ in one of my computers with an AM2 motherboard. Newegg has the 5800+ for 59.99 with free shipping, so I figured I'd consider it again. Do you think that it would be a noticeable upgrade?

Not necessarily, a die shrink usually means the chip will run cooler and overclock a bit better. You don't really see a huge performance gain. As for the upgrade, it really depends on what you do to tell if you will see a performance gain. I don't think you will see huge gains, maybe 5-10% in some things. For a cheap cpu upgrade the 5800+ is ok, keep in mind it's OEM which means it doesn't come with a HSF. If you want to see some bigger gains it might be time for a more modern platform

With the increase in cache and higher bus speed, there will be a noticeable difference, but probably not worth the price. If you were going to put some money into an upgrade, double it and get a quality cpu and mobo.

Thanks for the advice. I may end up just waiting until I'm ready to upgrade it to a new platform. My only reason for going with the 5800+ is if I think I can sell the 4800+ quite a bit. Thanks.

I really don't think you would get much out of that 4800.
March 6, 2009 10:47:25 PM

It looks like I can get about $25-$30 for the 4800+ on ebay. That'd make the 5800+ about half the price.

I can just use my heatsink/fan from my 4800+, so it being an OEM is okay.

If I were you I would get this. Same cache as the 6000+ and 6400+ but runs a bit slower at 2.8. with less watts and it is a Windsor.


Why would you recommend a slower, older, hotter processor that's more expensive?

The athalon has 512mb more L2 cache than the brisbane. Thats the reason for the price difference.
March 7, 2009 1:23:27 AM

Does 512kb more of cache really make a difference? Because I thought that the 200Mhz extra and smaller die would be more important.

Make sure that the motherboard you get is going to support the 125W processors before you purchase one. A number of boards won't work with processors over 95W. The other processor that is extremely appealing right now is the X2 7750 with the current price and $5 off coupon at NewEgg.

Not really on HT type processors like the Athlon Phenom or i7 (L2 anyway) by the way cache is fed by the HT link.

@ jj555298


There was a Pentium 4 965 that was out that had a stock speed of 3.73Ghz.
March 7, 2009 2:37:42 PM

just get an x2 7750.. imo.
March 7, 2009 3:07:41 PM

how about just overclocking the cpu

Dude you need to do some research on Athlon64 X2 CPU's. First of all the Windsor at stock 2.8 ghz is about the same as your Brisbane at 3.0 ghz. So it is not slower. It has more cache. Also it runs the same watts 89 as the brisbane. And it comes with a decent heatsink so it will run no hotter.

You also get a heatsink with the windsor, you don't with the brisbane it is an oem.

Why do you think the windsor's fly off the shelf at newegg when ever they are listed. You missed your chance the 5600+ Windsor is already gone.

^ Honestly, its not a notable difference.

Not worth upgrading over.

From his 4800+ that is true. He should just try to oc a little or get a better video card.
March 8, 2009 9:17:30 PM

I've decided to take your advice and try to overclock it. Hopefully I'll be able to get it up to 2.8Ghz or even 3Ghz. The video card is a BFG 8800GT OC, so I think it's fine.

Agreed, the CPU really is a bottleneck for a new video card and getting a slightly faster CPU won't really help.
