Hi new to the forum hope you guys can help me out

I have a problem I was looking over intel vs amd and apparently the core 2 duo conroe is more superior than the x2 windsors...

so my problem is I've considered a set up with an AMD 64 x2 5400+ at 255$
and I don't know if the e6400 conroe is better or on par at 222$.

i was wondering if there is anything better or on par the 5400 thats under 255$
courtesy of newegg

thanks in advance.

-edit-
I looked at tom's cpu chart, but unfortunately they didn't have the 5400 to compare and the e6400 on the cart wasn't a conroe.

More about : intel amd

...Not exactly contrarily to what prozac26 says; the X2 5400+ mostly outperforms an E6400 if you don't overclock. So the better price/performance is the X2 5400+; price is the same, performance is better.

People will think you are cooler if you go with the C2D. :lol:

You will need more expensive memory to make it outperform a 6400 with cheap memory. I would personally go with the Intel but don't care what you spend your money on.

Barcelona is too big of a word for a processor. Do you want to have to say that or type it everytime someone asks you what type of a processor you have or would you rather say in a calm clear voice " I got a C2D ".

See my friend, that is what being cool is all about. :)

Personally, I'd not buy my top chip now. (if it was urgent) I'd get something to overclock, probably a X2 3600+ or E4300 (more 3600+ because of K10 coming), and would simply sit and wait.

Well, less than a year ago, you were cool if you had a 939 but today I find my upgrade path end with the FX-60; 939 dumped :roll: I find it pretty hard to keep up with times.

I agree, maybe the OP should spend his money on a nice couch and the HBO package for his cable to keep him entertained until Penryn and K10 to out. :lol: 

Listen to the dinosaur guy, I am hopped up on cough syrup right now. :oops:

Do you find yourself alone on the dance floor doing the Mocereana while the football team laughs at you. This was me too until I discovered the C2D. With C2D I can impress my friend by running iterations of PI in 13.4612 seconds.

Hard to say for sure(like you said, it ain't out yet), but at least that GTS will be dx10 compatible. You probably won't be able to max it out, but it should still look quite nice.

I'd go for the E6400. It's better.
AMD hasn't a good relation price/performance as it did before the C2D's. Maybe the upcoming CPUs can balance the status.

Looks pretty good, cept a few things.. The Asus board is good, but take a look at the gigabyte with the 570 chipset, I like it better than the asus, compare the features and the reviews on them, but if u do, pay no heed to the people who say there is no way to adjust memory timings and voltages, Gigabyte just hides them a little bit.. The 5400+ is pretty sweet, but look at the price gap from a 5200+. Is that much $$ really worth 200Mhz, and u have half the cache too.... IDK mmuch about the firestix, but they are pretty cool from what I've heard.. Can't really go wrong right now with the GTS 320, maybe look at the eVGA models, I think there are some sweet rebates going on, and I like evgas warranty and CS... HDD seems fine.. Im partial to WD myself, but its all good... I would definitely urge you to change the PSU, I would say that it is a must, most smart enthusiast will tell you, that you cannot skimp out on the PSU, Id say get something like a Corsair 620W or w/e that one is.. I like my OCZ aswell.. But you should end up paying probably twice that for a good hearty PSU.. The case is fabulous, its cheap (cost) looks good, and keeps my case almost room temp, and even with the front vents there is not much noise, just some dust every now and then in the front mesh.. And not much dust gets inside either.... It also will fit any GPU short of 11ish inches, with minimal HDD adjustments..... So far looks good for a first revision... :D 
March 27, 2007 11:19:59 PM

The 5400+ outperforms the E6400 for almost everything. If you plain to overclock, than the opposite can be said. An OC-ed E6400 outperforms any OC-ed AMD CPU.
Right now there is only one reason to go after C2D, and that's overclocking. Else, AMD is the way to go. Their CPUs are more price/performance competitive at the moment, and the decent K8 mainboards are less expensive than the decent C2D mainboards.
BTW, next month there would be a price cuts form both Intel (22th April) & AMD (9th April). The E6400 price wouldn't be reduced a lot, but higher C2D models will be cheaper for 40% in average. AMD already reduced their CPUs prices, unofficially, but they'll reduce the prices further on 9th of April. So, you may want to wait.
March 27, 2007 11:20:56 PM

Please, don't confuse price/performance with performance/wat or something else; The X2 5400+ overall performs slightly better than an E6400 and has more or less the same price. Core2 is great but not every Core2 outperforms every X2 and X2 prices are mostly competitive until they can compete with performance (more or less up to the E6600).

See my friend, that is what being cool is all about. :) I'd go for the X2. But as an aside did you know that the actual code name for C2D was Cointreau, not Conroe.

Barcelona is K10.

The E6400 is better. Better price and performance.

Intel's Core 2's are better than AMD's A64, in pretty much every way.


The 5400+ will out perform the Intel 6400 in everyway at stock speeds. If you do not plan to overclock, then go with the 5400+. If you plan on overclocking, the Intel 6400 will give you greater potential to overclock.

Personal I would go with the AMD 5400+ if I was you.

hey fender22 this is the mobo you were talking about right? http://www.newegg.com/product/product.asp?item=N82E1681...


Yeah, thats it.. I suggested it cause its a good competitor with the Asus 570, and its a little less, I favor the gigabyte because I have always had good business with them, not to say I haven't with asus, but maybe you've noticed that I have the 590-S5 version of the gigabyte and am extremely happy. Both are good boards, I like the GB better but thats just me, If you wanna save a couple bucks the GB is there. Wonder what others would say.. U should get another opinion, and take what I have to say with a grain of salt because you should take almost everything with a grain of salt.. Picked another PSU?

heres a comparison http://www.newegg.com/Product/Productcompare.aspx?Submi...
March 28, 2007 12:41:58 AM

Personally, if I were on a strict budget and not an overclocker I'd go with the 4600 as offering the best price/performance right now. If I were spending over $200 however I'd probably just wait for the April 22 Intel price cuts and get a C2D 6600 for $224, less than what you'd be paying getting the 5200 now.

yeah i'm going to go with the gigabyte because it seems good from what i see and plus the price

I tried to look at the corsair 620 psu but man 170... thats killer

anything you could recommend that'd be under 100?

and oh thanks for the recommendation on the 5200

although i'd have to say i don't know how much difference cache does to the cpu? does it increase speed or something?

hmm good point... but then again i wont really be upgrading till like half a year down the road so i might as well go with the 5200

-edit-

well went and reedit my wish list and i think this is the final using the 5200+

Hmm maybe some PSU with a MIR Ill go see... Oh and the 5400 is alot of $$ more than the 5200 for not that much more performace.. The 54may have 200 more mhz like a said earlier but it has 512Kb x2 of l2 cache wilst the 5200 has 1MB x 512, and the cache does help, but GHz seems to help more... Idk, Id ask someone like jumpingjack or someone really smart on CPUs what is better to go for in the athlon x2 line, 200more mhz or more cache.. I think its mhz though.. but just the price between thge 5200+ and 5400+ doesn't reflect the performance gains.. too much but thats a personal thing for my wallet, maybe not urs... well it does depend on what video card u get, then I could reccomend PSUs better.. Oh yeah, we can't look at your wishlist cause its in your account thing..

March 28, 2007 1:55:42 AM

lol... how smart of me to post the wrong thing...
well as for starters:

Mobo: GIGABYTE GA-M57SLI-S4 Socket AM2 NVIDIA nForce 570 SLI MCP ATX AMD Motherboard

CPU: the 5200+

and GPU: is 8800 gts: PNY VCG88GTS32XPB GeForce 8800GTS 320MB GDDR3 PCI Express x16 HDCP Video Card

the other stuff is pretty much the other things i listed earlier only difference is the mobo and cpu

if you'd be so kind to point a psu i could use that isn't so steep in price

and fender thanks for all the help seriously thank you
March 28, 2007 2:01:18 AM

hey jumpingjack may i ask you what the cache importance between the 5200 and 5400 is because fender said you'd have a good idea about whether the cache or mhz is more important

i don't even know what cache is. lol
March 28, 2007 2:16:32 AM

yeah man, no problem.. I didn't discover forumz till after my first build.. I really wish I had.. so its good to help people that have found it.. and help them make good choices... Umm PSU... The Corsair has a nice MIR lowering it to like 140ish? but if that is still to mucho

http://www.newegg.com/Product/Product.aspx?Item=N82E168...
My PSU but 700W. and get this.. the rebate makes it less than the 600W of the same PSU.. Id snach it up if u can afford it, it amost gets to $100

http://www.newegg.com/Product/Product.aspx?Item=N82E168...
and

These coolermast PSUs Idk much about.. They seem pretty nice, and the price is good. But they cannot stand up the the beastly ferocity of the OCZ one above! :twisted:

http://www.newegg.com/Product/Product.aspx?Item=N82E168...
That could potentially be quite the bargin.. Id read up the reviews on it and see if it is in fact a good PSU

The First one is my first choice seing as it's 700W and it is a hell of a deal right now.. if u don't want :lol:  all 700W i'll trade you for my 600W version that i bought for more... :x There are better PSUs to be had.. but they get quite expensive.....

Edit looks like the egg is having some problems.. so yeah.. Idk or is it just me.. 7:25 [/b]

hmm... some good options, but budget wise i know i'm not supposed to go cheap on the psu, but i'm going to go for the coolmax thanks
March 28, 2007 2:47:32 AM

kk, your funeral... jk jk :D  .. But yeah, w/e u wanna do.. That cache thing helped me too! And its pretty cool.. I mean a 4800+ is still greater than the 4600+ (same Ghz, different cache) But its not all that important I guess.. GO IMC!! :lol:

Sure not a problem....

First, what is cache....

Cache in simplest terms is just a buffer. It is special memory that is designed to operate in clock speed at the speed of the CPU, and the goal is to be a temporary storage medium for data and code/instructions so that as the core of the processor completes crunching on one block it can retrieve the next block of data from cache which is much much faster than main memory DRAM.

When you run a program, the cache needs to warm up... as the CPU starts processing, logic within the CPU (called prefetchers) are looking at memory fetch patterns, soon it begins to predict the next segment of memory/data that will be needed as the CPU is working on other data. It prefetches the data, hence the name prefetchers.

Ideally, the needed data or code will always be available in cache when the core of the CPU needs it.... but the prefetchers are kinda dumb, they are guessers not prognosticators --- so there are cases where the CPU needs the next chunk of data/instructions and it is not there.... this is called a cache miss. When this happens the CPU must then go fetch the data from the slower main memory into cache to begin working again.... and the CPU has to wait on that data.

Generally speaking, the cache miss rate goes down as the amount of cache goes up.... so large caches do not have nearly as many misses and do not stop to go to main memory as smaller caches do.....

Having said that, this is important to understand --- if you design your chip to have 'small' cache relatively speaking, then the desire is to have a FAST access path to memory.... this is what AMD did when they designed the integrated memory controller.

Conversely, if you have a large cache, relatively speaking, the speed of the memory access is not as important because there are fewer calls to main memory.

Now --- the cache miss rate discussed above, as I said, decreases as chace increases.... and it is geometric the miss rate decreases going from 256 KB to 512 KB more than going from 512 KB to 1 Meg. There are several papers concerning this you can find... but by the time one reaches 4 meg... the cache miss rate is typically less than 1% of the total number of calls to cache as I recall.

On the AMD platform --- with the IMC (integrated memory controller), their design does not need or include large caches as their main performance enabler, since the access to memory is faster more or less. The difference you see in 512 to 1 meg on AMD is not huge, about 5-8% overall (again as I recall, I will not post links or data so others can correct me with data if I am way off).

However, and this is the achilles heal of the AMD approach.... the overall CPU performance IS sensitive to the speed of the memory you choose.... so DDR2-800 shows a significant improvement over DDR2-667. This is not true with large cache systems (C2D is larger cache), so you will see invariant performance in memory speed for a core 2 duo... DDR2-533 is good enough to get good numbers.

In short, DRAM speed has more of an impact with AMD processors than cache size, 512 vs 1 meg... do not go for the 1 meg part.....

holy sh*t thanks jack...

People will think you are cooler if you go with the C2D. :lol: 

Wait till Barcelona comes out and they'll think you are gay :lol: 
Barcelona is too big of a word for a processor. Do you want to have to say that or type it everytime someone asks you what type of a processor you have or would you rather say in a calm clear voice " I got a C2D ".

See my friend, that is what being cool is all about. :) I'd go for the X2. But as an aside did you know that the actual code name for C2D was Cointreau, not Conroe.

Barcelona is K10.

Did you know that the actual code name for K10 was Antidisestablishmentarism, not Barcelona.
