I'm a strictly Intel guy but I want to know how AMD measures up.I know they lose vs Intel one-on-one but what is the hierarchy between those three processor families(generally speaking) ?

Benchmarks, anyone?
 
The top phenom 2 quad (3.4GHz) is overall a tiny bit better than a Q9950 2.8GHz. Just to give u an idea on performance.

Who's better matched clock for clock?

Also, as far as I knew, the order of Athlon II vs Phenom vs Phenom II went like

1.Phenom II
2.Athlon II
3.Phenom

Anandtech had some benches like that.
 
It all depends if you are going to OC or not. The AMD is cheap and has overall slightly better performance, but i bet it wont overclock very much. The Q9950 will OC well and will out perform the AMD, but it is more expensive. My Q9950 is on 3.6, concidering my cpu nearly as good as AMD when it was running at 2.8, it defernatly a lot better than the AMD now.

Phenom II and Athlon II overclock just fine. Most Phenom II will do 3.8/4.0 with a good board and aftermarket cooling. I think the record is like alittle over 7ghz. Hell the Phenom II 720BE I have will unlock to a quad and overclock to 3.8 with only 1.425V. Most of the Athlon II will do 3.5/3.6 easy, some higher depending on what model it is.

87dtna had a Phenom II X2 550 unlocked to a quad running at 3.8. Not to bad for a 99 buck processor.

It was benchable at 3.9ghz, but yeah getting a 550 to unlock is a crap shoot.


Phenom II is the best AMD has right now.

Athlon II VS Phenom, well thats a toss up but I would give the edge to Athlon II because they typically overclock better and have newer tech so they create less heat.

All the Athlon II's I tried barely make any heat at all. I had an Athlon II 245 at 3.8ghz that wouldn't even go over 50c with a thermalright ultra extreme 120 cooler.

As far as AMD VS intel, core 2 duo's are even faster than AMD's Phenom II 550 dual core. For a more direct comparison, the Pentium dual core's are about the same clock for clock as Phenom II dual cores (545/550).

As far as quad cores, a Phenom II 955 is about the same performance as a Q8400. A Q9400 edges it out slightly, this is clock for clock. I believe at stock clocks the 955/965 would edge out a Q9400.
But once you get a Q9550, or any I5/I7 quad, intel crushes AMD.
 
I've had both and for gaming they are pretty much identical. Benching on the other hand is a different story and depending on your cooling for each you will get a variety of outcomes.

I can agree with that...there was no CPU bottleneck with the Phenom II as a quad at 3.8ghz, max CPU usage was around 50% while gaming. With the I5 at 4ghz however, max CPU usage was only 25%. All this means is the Phenom II would eventually, once games are more CPU demanding, would bottleneck before the I5.

i have an amd athlon 64 x2 5200+ Brisbane stock at 2.7 ghz that is now running at 3.28 ghz completely stable. i know this doesn't really apply here but i am just saying that amd cpu's DO have overclocking potential (though maybe not as much as intel apples to apples; i don't know since i have not actually had an intel cpu).

AMD was known for not being very overclockable UNTIL their 45nm cpu's came out.
And no they still don't OC as well as intel.

Most 45nm amd's will OC about 20-30% over stock, Intel's 45nm 40-50%. Some are better, some are worse. I know of Phenom II 720's that have unlocked and overclocked to 4.2ghz on air, but some don't unlock and don't go past 3.8ghz.
 
My Phenom 965 (125w) I have been able to get 4.2ghz on aftermarket air cooling. The best cpu score I have been able to get according to 3dmark is 5900. Unless I do phase cooling or something with a peltier and water cooling that is about the best I am going to get with this chip. If I remember right 87dna i5 @ 4ghz was getting 6500 cpu score so it seems intel is kicking AMD in the butt. I can not believe AMD is not going to release there new chips till next year (2011) what a bad move on there part. They better crap or get the pot...

Don't they use different core designs?

As far as the Athlon II and Phenom II, they use the same core/s. The difference is how much L2 and L3 cache they have. The Athlon IIs that have 512 of L2 are decapitated Phenom II and the Athlon II that have 1mb. of L2 are true dual cores but still have the same core design.
