Pre-release Tests Conducted on AMD Denreb
Pre-release Tests Conducted on AMD Deneb
AMD Deneb is the code-name for the 45nm quad-core CPU which AMD plans to release soon. Chinese website ITOCP got their hands on two engineering samples. They used these samples at various clock-speeds set by altering the FSB multiplier and Vcore voltage. These chips were then subjected to rounds of Super Pi 1M benchmark. The results look rather luke-warm compared to what we saw of the Intel Bloomfield chips recently. The Deneb CPUs were supported by an AMD RD790 motherboard and 2 GB of DDR2 800 MHz unganged memory, running at timings of 5-5-5-18. The Phenom X4 Deneb 45nm will feature 6 MB of L3 cache apart from the usual 512 KB L2 caches dedicated to the cores.

Good thing there are a lot of people that follow AMD in this thread!:ohwell:
If you've been paying attention the last two forevers AMD's do not put up the same type of numbers as Intel processors in SuperPi so stop expecting it to put up a 10 second time because they NEVER have!
Now if you use 1% logic and 2% effort you'll go over the old SuperPi results from previous AMD processors and notice that this is a very nice improvement for these processors! My best SuperPi time to date is 24.679s in the 1M test with everything turned up as high as I can get it (3.1Ghz)...the new processor even with nothing turned up will nearly match that at only 2.8Ghz!!! That's a fantastic increase overall and I'm damn happy with it. For those wondering (and waiting to throw more mud) my setup for that test was... (all air cooling Xigmatek HDT-S1283 on low)
Phenom 9850 @ 3.1Ghz 1.37v
Patriot Extreme 1150Mhz 4-5-5-15 2T
Northbridge 2.354Ghz
HT Link 2.14Ghz
Anyway I'd love to see some other tests done with this but right now I'm sold already ESPECIALLY with the L3 6Mb cache as that'll help a lot in other apps we really needed the speed in.
On another note and without sounding terribly rude but...why do people with dual cores keep posting what clocks you can achieve on "x" voltage...nobody cares what your DUAL core can do. You quad guys on the other hand are a different story though because you actually have apples to apples going.

I'm done let the kids have their fun...your turn

I hope AMD has some headroom for overclocking. The small performance gain is nice, but we still need more if AMD is going to try to compete with Intel.
My old Venice 3000 at 2.6Ghz and OC'd RAM did 18 seconds in SuperPi, I was happy with that lol.
Just because a processor comes at a certain speed doesn't mean that's literally what it took for anybody to get that speed. systems differ..my low voltage thread pretty much proves that completely. I can boot 3Ghz as low as 1.20v on all four cores but it takes a small bump to get it stable. Btw, I wish they used a different 790 board I'm not a fan of the MSI FX board at all...the bios doesn't have nearly enough options for the Phenom.

Homework assignment for you: Define the word "competition"...then define the word "we"
Forgive me if it seems as thoguh I'm slinging mud at you; just saying choose your words more carefully and check as many facts as you can first. :) Dayumn! That's really fast! :toast:
Why can't all Intel guys and AMD guys get along like this...in the end we're all computer people.:shadedshu

You got an awesome chip. :eek:
and just to ask WHEN HAS AMD BEEN GOOD AT sp? what i'm seeing is they are doing alot better clock for clock and th scaling looks very good on these chips
Intel fanboys......???
To be a fanboy you would buy a sub par product over a better one just because of your brand preference. Thats a fanboy..... an AMD fanboy.;) Some AMD's are a good price but there quads are not if you like to OC.
Buying a Pentium D over a AMD X2 would be a fanboy thing to do. (when they were in the competition)
I just pointed that out because somebody felt the need to call Intel purchasers, fanboys. :shadedshu
The AMD dual core processors are still pretty awesome in their Black editions. When will Intel get those awesome Multi's. :(
I am glad there are people out there willing to buy AMD processors because if they didn't, we all know Intel would charge us whatever they pleased due to lack of competition. Although I would like to see AMD step it up in the Quad department more than what we have just seen. Mainly because I don't think Intel is really feeling the heat from AMD, despite the high voltages in those benches.:)

I think that's rather absurd - what I see here is an AMD CPU that appears that it will perform more on par with some of Intel's quads . . . that right there is enough for many OE companies to start designing systems . . . and if AMD prices it low enough to be pricer:performance competitive, for both consumers and OEMs, this CPU definitley comes across as being able to help AMD start getting their foot back through the door.
And this is still just an engineering sample - not a finished product, yet.
We must be happy that these Denreb parts are overclocking well. They took a 2.3 GHz to almost 3.5 GHz alebit unlocked multipler and voltage.
There are still Intel fanboys who believe that you can't get better than Intel, and in raw performance they aren't half right, but having used Intel for over 18 months now as impressed with the raw performance and incredibly high benches, I'm looking for something more stable that will last me longer (IE no socket changes or being forced to change motherboard to use the latest tech).
