Here comes Propus

All the awesomeness of a $100 (sub-$100?) quad aside, this finally gives us the chance to answer a question that's been burning a hole in the back of my mind for awhile: will Propus offer better NB overclocking than standard Phenom IIs? Is it the L3 cache that really holds back traditional X4s in the NB overclocking department?

And just how fast would the NB and memory have to go to make up for the total lack of L3 cache?

The mind boggles.
 
there already one seller on ebay selling the 620 for $99.99 with free shipping. $92 with bing cash. just search for "athlon 620"
 
Does the NB overclocking do anything for performance without an L3 cache? Only the memory controller and L3 cache are on it, and the speed of the memory controller shouldn't make any difference.
 
It'll be interesting to see how well this cpu does for gamers and wether it will affect Intel pricing or not.

this thing might be technically average but it's irresistible as a OC price piece! dying to see what it can do at high clocks.

That's the first review I've seen that has overclocked the Athlon II X4 to near 4 GHz, the same levels as the Phenom IIs. Most places seem to have trouble with overclocking. Some have attributed it to the low locked 13x multiplier.
 
I haven't followed the latest AMD technology, but this price point caught my eye. Plus, the ability to use older/cheaper DDR2 was a nice option.

Most MB manufacturers haven't updated their sites for this proc. But, what would be the cheapest DDR2 platform that I could use the cpu on? One site suggested the 785g boards with DDR2-1066. Could I use DDR2-800?

Would the tips in the "Is my motherboard compatible with Phenom II?" thread help? E.g. someone suggested the Gigabyte GA-MA69G-S3H.

Yeah I noticed that a couple weeks ago too. I guess they realized they were selling it too early, but it should be back soon I reckon.

The 620 on Newegg before was a Deneb where they just disabled the L3. People were buying them in droves and then unlocking the L3, so they took it down. It was too good of a deal, I guess.

The 620 that is selling now is actually the native Propus. If you're running at stock and didn't do any of the unlocking tricks, the only difference between the two 620s would be power draw.

well if that was the case I should had gotten one then lol.

Suggested is 785G with DDR2-1066 because 785G is the newest mainstream chipset and DDR2-1066 is the fastest DDR2 memory. You should be able to run this with any DDR2 memory and on the cheapest AM2+ motherboard you can find.
 
I haven't seen any reviews, yet, include the original Phenoms. I know the 9650 usually sells around the $100 price point, and I would like to see clock-for-clock 9950 vs. 620. I know I could probably extrapolate data across several reviews, but I'm feeling lazy today.
 
I have a 720b triple core that runs very well. I have overclocked it to 4ghz with only a small increase in core voltage. 4.1ghz was not stable, but at 4ghz thats a 1200mhz overclock. Not to shabby for a cpu with a disabled core and 6megs of L-3 cache. I hope this new cpu does well in its segment
 
What most intrigues me about the $99 620 is how it might affect the competitive landscape. If this chip is popular then we could see significant price reductions from Intel in both low end Quads but also some dual cores. TWT
 
Still, I think that the Q8200 at Microcenter for $99.99 was a far better deal. Overclock that sucker to 3.125Ghz @ 450FSB, and it was a screamer, with far better performance than an Athlon II X4, at nearly any clock speed.

Just wait until Intel answers AMD, with a 2C/4T 32nm chip with better performance, that I'm sure that Intel could price cheaper than AMD if they wanted to.
 
This chip would be good for a HTPC. Quad for encoding and decoding while watchin/recording tv.

Yes, that would be good. Looking forward to a cheap Q9xxx. 🙂 But I think I'll be buying a A II to replace a old AM2 3600+ anyway - it should work, at least in theory.

In a word, yes. It affects the overall latency of system RAM by quite a bit (as measured in cycles), along with the maximum effective memory bandwidth (though it is not bandwidth, or a lack thereof, that threatens K10-based chips . . . or at least not that I can tell). The memory controller on K8 scaled with the clockspeed of K8 processors, but since it is clocked independently on K10, then this is not the case unless the NB speed is increased proportionately to the clockspeed increased of the cores. In fact, on K8, I think the imc was never more than 200 mhz slower than the core(s).

From what I've seen, K10 could certainly use lower system memory latency, but achieving this has not been so simple due to slow NB speeds. There's a real limit to what you can do by speeding up your memory and/or tightening memory timings if the NB speed can not be increased along with the processor's clockspeed beyond a certain point.
