*OFFICIAL* AM2 Discussion - Page 10

post #91 of 126
Thanks for the input guys.....I went ahead and purchased the MSI K9N Platinum MoBo and 4000+ X2 (with 1MB Cache) AM2 CPU from Monarch. I'm an AMD fanboi, so they can have Conroe....I think 1st Q '07, AMD will put Intel back in its place....Bwa hah hah hah.....I do enjoy the competition though....keeps AMD honest and off its laurels.

They had the parts in this morning and I figured it would be failry upgradable for awhile. Mom's system needs help now...heh.....plus I want to tinker...

I'll Build my new system after the bugs are worked out and DDR3 is out in Q1 of '07, prolly with all the same hardware as moms puter sans the mobo, cpu and ram.

Hello,

I wanted to make a small point on some reviews I've seen today. I have AMD cpu, but I'm no fanboy, but I buy the best performance/price. Now that's cleared up let's go on to the point. As you may have noticed Anandtech.com and Tomsharware.com posted their reviews a little later than the others and I waited to see them too before making an oppinion. After all they seemed to me to be the most reliable sites as I was reading them since 5 years ago. There are the links in case you haven't seen it already:
Tom http://www.tomshardware.com/2006/05/...nvents_itself/
Anand http://anandtech.com/cpuchipsets/sho...spx?i=2762&p=1


What I have found is two different points of view, wich is quite normal in the end: one pro-AMD and one against-AMD. The other sites were quite neutral. You can find other reviews here:

http://xbitlabs.com/articles/cpu/dis...ocket-am2.html
http://techreport.com/onearticle.x/10023

First of all I read tomshardware's 62 pages review during wich they bechmark the new A64 AM2s concluding there's not a performance gain between the sk939 and sk AM2.
Quote:
With Socket AM2 the (OEM) customer now has the option of DDR2 memory from AMD too. In theory, that should produce a higher memory bandwidth, which in practice is only achieved by the expensive top processors. Compared to "old" DDR memory-based platforms, the bulk of AMD's CPUs cannot benefit from the higher bandwidth of the DDR2 memory.
Anand concludes on preety much the same thing in regards to the transition from sk939 to AM2:
Quote:
It is ironic and equally unfortunate for AMD that on the eve of Intel finally getting its act together, that the Socket-AM2 launch is so devoid of any sort of performance improvements. It's clear that AMD's architecture just simply isn't starved of memory bandwidth at this point, and it will take either higher clock speeds or architectural improvements to make the move to DDR2 necessary.
Everything is fine from this perspective, but there is a catch. They both made another comparison: how does the X2 4000+ behave when compared to the similary priced Pentium D 950. Here there are huge differences in their point of views.
Tom's H:
Quote:
Comparing the low-priced Athlon 64 X2 4000+ (2.0 GHz, 2x1 MB L2 cache) with the Intel Pentium D 950 (3.4 GHz, 2x2 MB L2 cache) costing the same, we do see a performance advantage of up to 20 percent.
They also add this graph:
I guess it is obvious who they is the winner if we look only at this.

On the other hand Anand makes the same analisys between the x2 4000 and the 950 but somewhat different results:




Anand's comclusion on various benchmarks:
Quote:
DIVx: DivX performance is extremely strong with the Athlon 64 X2 4000+ and 3800+, but once again we see absolutely no performance difference between the two CPUs. Both AMD offerings are able to significantly outperform the Pentium D 950.
WME9:The Athlon 64 X2 4000+ manages to pull slightly ahead of the 3800+, but the two are basically tied. The Pentium D 950 is far more competitive in the WME9 test but isn't tangibly faster than the X2 4000+
Gaming - Oblivion: As we saw in our Oblivion CPU comparison, this game really favors AMD's K8 architecture for all of its strengths and severely penalizes the Pentium D for its NetBurst roots. The Athlon 64 X2 4000+ does continue to hold a performance advantage over the 3800+, but it isn't as large in Oblivion as we've seen in the previous two games.

I can say the differences between these sites are totaly outrageous. Anandtech compares the x2 4000 with the 950 and finds it is equal if not better in certain tasks, and Tomshardware says the Pentium wins 30 out of 35 benches. Honestly it is obvious that one of them either posted fake results or ran optimised benches wich questions their credibility.

I thank the ones that managed to read this post and I'm asking you: what do you think? Are we suppose to benchmark ourselfes the CPUs before deciding what to buy?

Well not sure what kinda of difference it makes in the benchmarks they are comparing, but the Tom's Hardware review is using 2x512mb ddr2-667 ram at 4-4-4-8 timings, while the AnandTech review is using 2x1gb ddr2-800 ram at 4-4-4-12 timing. Maybe the AM2 cpu's don't provide as much performance with slower/less ram when compared directly to Intel D series, but come out about equal with better ram.

I now have 12 reviews posted up. I am sure that is quite a large number 24 hours after the product's release.

Even though I just recently switched to Intel I still want the K8L to crush the conroe, maybe it is because I'm just sick of hearing conroe, conroe, conroe, conroe all day long. I wonder if it will be similar to the GPU wars where Nvidia releases some killer gpu then ATI releases something slightly better, I bet we can expect the new AMD architecture to perform slightly better then the conroe.

What's up with most of the chips in AM2 having only 512kb of L2 cache? Seems like a lot of the single core chips are only 512 kb of L2 and the X2 5000+ has only 512 kb of L2 cache. It's odd to me that they would be keeping the L2 at 512 kb instead of bumping everything up to 1 mb... This is especially puzzling if you look at how all Intel chips now have 2-4 mb of L2 cache....

Hey guys, I am about to have about $1,700 come my way, and I am having a really hard time making up my mind. On one hand I can get an opteron 165, and a good overclocking motherboard, and pretty much be set up with a FX-60. But on the other hand I could get an AM2 X2 4000+ which at stock is 200Mhz faster than the 165(like that matters), and still have the 1mb of L2, but I would also have DDR-2, and the new socket. Which do you all think is the better choice?

edit sorry I wasn't paying attention.

:withstupi 2Ghz faster where did u get this number?the Opty 165 is stock at 1.8Ghz 200*9 and the M2 4000+ is stock at 2.0Ghz 200*10 thats only 200Mhz not 2Ghz

If you are upgrading from a system before 939 or from Intel, and you cannot wait for Conroe, then do not hesitate buying an AM2 motherboard. They do very well in terms of overclocking, and they are remarkably stable.

On the other hand, if you currently have a 939 system, just upgrade to the Opty.

If you can wait for Conroe, wait for it.
