So this X6 thing...

[VirtualLarry]

They already support 4 channels on the Xeon 7500. Of course its not a direct competitor.



REALLY? http://anandtech.com/show/2774/5

Are you high?

hmm. I though I read that somewhere. I also recall Rubycon asking why all server deployment guides recommend disabling HT. I also recall JFAMD saying that HT doesn't scale, but real cores do.

Btw, what socket is the Xeon 7500? That's not an Itanium, is it?

edit: interesting. But the memory bandwidth of the 7500 is still lower than MC. http://www.anandtech.com/show/3648/xeon-7500-dell-r810/3
edit: I counted wrong, I didn't realize that there were actual 4 SMI channels, not two. So it looks like the 7500 has 52GB/sec of memory bandwidth. It would be nice to see a STREAM benchmark for it.

Edit: Microsoft recommends disabling HyperThreading. http://technet.microsoft.com/en-us/library/dd346699.aspx

What's the stock uncore speed on the 750?

The uncore speed of the i5 750 is 2.13Ghz same as the i7 920.

BTW, if 1055T turbos to 3.3 GHz, that means multiplier is up'ed to x16.5 from x14. I wonder if motherboard vendors will figure out how that works and make the additional multipliers available to end-users?

Bulldozer will appear on both AM3 socket, and G34 (server) socket, last I heard. I don't know how many memory channels G34 has, but I think it's four, as two 6-core dice appear linked in the 12-core Magny Cours chip, and each of those dice has two memory channels.
So really, just like HyperTransport's multi-CPU scalability versus Intel's QPI, Intel is finally catching up with AMD, as far as memory channels go with socket 2011.
AMD's architecture has been leading Intel's, in the server space, for a number of years. Ever since the Opteron out-distanced itself from Intel's poor P4-based Xeon chips.

Here's a diagram that states that G34 sockets have four memory channels. http://techreport.com/discussions.x/16797
http://techreport.com/articles.x/17005/2
These are servers that you can buy TODAY, you don't have to wait for socket 2011 like with Intel.

PS. I can help but rub it in a little bit, not to mention that the HyperThreading feature of Nehalem-class CPUs is worthless for server workloads.

Edit: You're wrong about one thing, AMD is going to have FOUR sockets, not just three. Two for server (G34, C32), the LLano APU socket, and AMD3. Some say AM3+ is coming out too.

Edit: MC STREAM results - 42GB/sec memory bandwidth. What does Intel score with their triple-channel setup? http://www.xtremesystems.org/forums/showpost.php?p=3995220&postcount=54

Edit: Just as I thought, Intel is slower. http://www.advancedclustering.com/company-blog/stream-benchmarking.html

Larry your not rubbing it in at all were debating all is fair. Ya I forgot about G34 . But I do believe intel has dominated the server scene as of late . G34 going to be a harder sell than you think . I believe G34 is 4 way . pretty impressive low clocks. But ya got a problem . Intel 32 nm 6 core is coming out shortly for servers . Guess what its 8 way that 48 cores AMD has a max of 48 cores also . So intel turns HT off and at same clock as Mag. cores Intel Kicks AMD ass yet another time . Larry I don't want to rub it in but Intel has an ans for every move AMD tries to Make. On this generation intel needs only 3 channel memory . Your doing all right . But you leave so much out . I won't go into as most people Know intel also has a 8 core CPU just released . To bad I wasn't going to go all this far but what the hay . Thats what debates are for, Your turn

What the heck does any of this have to do with the OP?

(welcome back, IDC, by the way).

As much fun as it is to discuss the server market, Thuban/x6 products are not targeted at the server market. So . . . why bother? Please, go start a Magny-Cours vs Westmere/Beckton thread if you like.

Secondly, I'm sorry, but there's no way I'll ever buy another dual core for my main machine, even if it is an i3 or Sandy Bridge. You can complain about review sites all you like, but you sound no more credible doing so than people over at AMDZone who complain that the review sites are all being paid off by Intel.

Two sides of the same coin.

x6s are worthy chips. They are not "overpriced". People here are excited by them because they offer good real-world performance for the money, and they aren't heaters either. They represent a flat-out upgrade from Deneb-core Phenom IIs. They go straight into AM3 and some AM2+ boards with a BIOS upgrade (unlike Agena/Phenom, which was touted as being AM2-compatible but which wound up being unsupported on most AM2 boards). What's not to like?

Don't hate on a good chip. Lots of people here are going to buy them, overclock them, and enjoy them. If i3 had ever been something that they wanted or needed, they'd have i3s by now.

100% agreed lol

Wow, first time posting on here and it seems the topic generated quite the, uh, "debate" as it were. All the while, I've greatly appreciated reading through said debate and all the info and opinions expressed. I thank you all very much for the input.

 

[wiedersehen]

Also thank for your sharings! May you have a good time when OC!

I've never understood why people think it's smart to put high voltage devices into an almost air tight compartment then use annoying plastic fans to keep it all cool. Retarded logic IMO. In fact, I don't have a single case fan in my x3 rig overclocked to 3.73ghz and I idle at 18 to 20c, load at 46 to 48 with a 120mm fan running at a constant 1200rpm (I think, might be lower) on the cpu. Sitting next to it is a pleasure, as the only two fans running are the cpu fan and the fan on my video card, not even noticeable if music is on.

It's all about dissapation, and having an enitre room full of air to work with as opposed to a small air compressed compartment makes all the difference.

Come to think of it, I don't have a single case fan in *ANY* of my rigs anymore; and they're all overclocked to their max potential. I use to volt mod my fans until I got rid of them completely. Now I just find the biggest copper heatsink I can get and marvel at the low noise/temps.

All you need to do is cut a huge hole in your case door and use some common household screen door material to keep the insides safe. That or just remove the door/case fans completely and construct a door out of that same material.

The more exposed your hardware is, the less cooling you'll need. I run some pretty heavy overclocks and noise is never an issue using these tactics.

can you post a picture of your rig please?
