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.

I dont need AMD to be King Dingaling in the procs. I need them to be competitive and offer price/performance. If you ask me, I believe they have done that. I dont need the fastest, hell most of the world dont need the fastest. If you need AMD to make a proc to kill an intel proc, you seriously have issues. If you are happy with what you got, terrific I applaud you. Im going to stay in AMD and I plan to move to either a 9850 BE or a 9950 (or one of these 45nm Quads when they are released if priced right).
Let's try to keep things in perspective.
K8 and K10 (and apparently K10.5) don't do particularly well in SuperPi, when compared to Conroe/Kentsfield or Wolfdale/Yorkfield. This is perhaps the worst possible way to compare the Green and Blue teams.
For example, it only takes a Wolfdale/Yorkfield operating at 2.40 GHz to achieve 1M SuperPi in approximately 20 seconds and it takes a Deneb @ 3.44 GHz to achieve the same time. A Deneb @ 3.44 GHz would decimate a Wolfdale/Yorkfield @ 2.40 GHz in virtually every single benchmark or application (other than SuperPi). In my estimation, that is why these SuperPi times were allowed to be leaked… because it doesn’t truly reveal the performance potential in just about every other scenario.
Here's another tidbit to consider. At 3.00 GHz Current Agena (65nm) Phenoms achieve 1M SuperPi in 27.531 sec and the new Deneb (45nm) Phenoms in 23.547. That's a 14.4% increase in single-thread performance, at the same clock. This will erase and overcome the (approximately 8%) clock-for-clock advantage Yorkfield currently has over Agena.
In other words, clock-for-clock, these Denebs are likely to be as fast as or faster than Yorkfields in most scenarios (outside of SuperPi).
This demonstrates how Bloomfield and derivatives are an absolute must for Intel, rather than a technological luxury.
If the NB would be jacked up and the L3 ran like cache is supposed to be (full core speed), then superpi time would be fast. Idk wtf their problem is. It's a simple solution and it's not like it can't be done easily.
775 may have been out for 4 odd years, but can you go out and put a brand spanking new 775 chip in a board from the early days of 775? No.
Can you put the latest AM2 chip in an AM2 board from the early days? Yes, sometimes via BIOS update.
However, you can put one in a board from 2006, which is the same time AM2 was released.Exactly, a lot of the CPU support issues has to do with the manufacture of the board. There is no universal truth. New AM2 processors will not work in all AM2 motherboards. Just like not all 775 processors from 2006 will support the latest Processors. However, my P5B that I bought mid-2006 still supports the latest quad-core processors. So the current 775 socket has been around for pretty much just as long as AM2.
But now that we've gotten over my name, you have to admit that even though intel has not changed their socket in a while, every time they do a little revision you need to buy a good motherboard to run their "latest cpu's" even though it is socket compatible, call it what you will but i think that's reality, Amd has given people are better upgrade path.
Whatever people say fast slow dumb etc, can't beat a Local Frys sale of ECS + X2 4800 for $70. Thats what a stupid celeron + ecs mobo go normally. 4800 can do lots and lots of work way better than that celeron. That is called best bang for buck. Who cares if you walk around in the street naked with your stupid intel performance crown:D (because you don't have money to buy other necessary things)
The only major change to the socket was done when the Pentium Ds were released. Most boards after that should support all the processors through the 45nm processors as long as the chipset supported it, and
Hopefully there will also be a higher end Phenom FX's with this generation. With a full speed HT Link (3.2GHz Core, 2.6GHz HT). Wouldn't make it a top of the line CPU (Intel Nehalem will be faster), but at ~$300 it would be hard to beat for that price.
Now then...before making dumb comments like that read the rest not just a single line. And what exactly do you compare the new Intel processors to...newer ones? No you compare it to older ones.:shadedshu
While we're at it...define "crap" when it comes to performance. Because something is not faster than something else does that make it crap? What do you drive because with that statement I'll have to consider it crap. Just because something MAY not be as quick doesn't make it crap, it's just slower. Last time I checked all of these processors from both camps are very very fast just maybe not as fast as you want them, but I guess if that was true you made sure you bought the fastest thing out there...oh wait nevermind.
Speed is a very relative term people should get used to it.
Have you ever got mad because you had to sit and wait for 3 seconds longer for a program to load or lost 7-10 fps in a game when running at 75fps ...prolly not

Btw, that was a really long run on sentence though :roll:
Poeple may be able to get similar performance from Intel once you overclock the shit out of it- but not everyone sees the point in taking a gamble with overclocking whether it be with frying your kit or you simply got a bad chip. Overclocking is for enthusiasts not the common market. For god's sake I don't get this idea that tech enthusiasts are always promoting to everyone and their grandmother, 'just overclock it.' What a fucking stupid thing to say. Yeah void the warranty, and potentially break the hardware for a performance gain that WILL reduce the life of the chip no matter what you do. A 4800 is more than enough for most people- 90% won't be able to notice the difference between an AMD 4800+ X2 and an E8500 in realword applications unless they actually time how fast things take. We notice because we really care about it and want the best out of our machines. Using arrogant tech enthusiasts' logic is similar to Max power magazine's readers telling everyone they know to pimp out their cars to get max performance and huge exhausts from a car they use to take their kids to school. Think about whats a stupid argument before you apply your bigoted comments.
No offense, but you definately didn't do your research when you made the claim "shitty current quads". And what do you consider low speeds for the Northbridge, yes 1.8Ghz isn't the fastest of all the Phenoms (which makes this even better for the results) but that doesn't make it slow. Also remember on a Phenom we can just turn our speeds up because we have control of all the cpu parameters unlike the Athlon lineup (and yes I've owned those too).
No offense to anyone in this thread but there is only a handful of responses that should even still be listed here as legit responses to the thread, the rest should be deleted or the thread should be locked because it seems as though 90% of the people posting here are only here to throw dirt as opposed to make legit comments useful to anyone.
