Basic Features: Athlon 64 90nm Processors
The new 90nm Athlon 64 processors were only introduced for Socket 939. Since 939 supports Dual-Channel memory, the speed ratings are a bit different than Socket 754 processors.| Athlon 64 Socket 939 - Specifications of New 90nm Processors | |||
| Athlon 64 3000+ | Athlon 64 3200+ | Athlon 64 3500+ | |
| Speed Rating | 3000+ | 3200+ | 3500+ |
| Actual CPU Speed | 1.8Ghz | 2.0GHz | 2.2GHz |
| L1 Cache | 128k 64k Code Cache + 64k Data Cache |
128k 64k Code Cache + 64k Data Cache |

| L2 Cache | 512kb | 512kb | 512kb |
| Memory Type | Dual-Channel Unbuffered DDR | Dual-Channel Unbuffered DDR | Dual-Channel Unbuffered DDR |
| Memory Speed Supported | Up to DDR400 | Up to DDR400 | Up to DDR400 |
| Maximum CPUs | 1 | 1 | 1 |
It is interesting that AMD rates the 1.8GHz Socket 939 90nm 512k CPU as 3000+, while the Socket 754 1.8GHz 512k 130nm is rated as 2800+. Speed ratings for 939 chips are generally higher than their 754 counterparts. AMD believes that the higher performance of the Dual-Channel memory controller justifies these rating differences.

I agree with #3, some more numbers would be nice, preferably at least one Northwood, a Prescott, and a S754 3400+(2.4ghz).IceWindius - Thursday, October 14, 2004 - link
Wow, I wonder what types of memory will work best with the Athlons in the .90 die size? I'd love to be able to get a 3000+ at 2.6 and have extra money in my pocket for other things! Sucks that nForce 4 won't have AGP for my 6800GT so I'll just get a Asus A8V and stay with AGP for one more generation.Go AMD go, I can't wait to get rid of my intel setup and go back to my one and only AMD!

Sweet article and good results. 90nm is predicted in my near future.Bugler - Thursday, October 14, 2004 - link
Thank you for the write of AnandTech. We have been waiting for some guidance and this is much appreciated. I will probably buy the rest of my AMD build (motherboard and CPU) next weeks. The rest of the parts have arrived. Was just waiting on an assessment of the 90nm chips.ariafrost - Thursday, October 14, 2004 - link
And I thought the days of nearly 50% overclocks were long gone (I had a Celeron 300A @ 450MHz waaayy back)...My next proc will be a 939 90nm part, and mobo will be Nforce 4 :)

Nice finally be able to afford a socket 939 just got to wait to some NForce 4 boards come out and have revision 2 so they have 1GHz HT.Theres a couple of other typos such as saying "but they confirmed that the AMD 130nm process appears to run at least as cool as current 130nm processors."
I believe it should have said on the first 130nm (90nm).

I'm having problems finding benchies that compare these new cpus with my current rig.... how much of a performance gap are we talking about over a 3.0 northwood? 50%?Decoder - Thursday, October 14, 2004 - link
Thanks for this super article. My next upgrade will be a AMD64 3000+ on a NForce 4 board! Kudos to AMD.Degrador - Thursday, October 14, 2004 - link
These look like great chips - I'd say my next processor will be a 90nm 3000+.Btw, you've got the table a little screwy for overclocking - the processor speeds are labelled the wrong way around, and for the 3000+ overclock it should be 2592 (assuming 288x9).
