Q8400 vs. E8400

Forum CPU & Components : CPUs Q8400 vs. E8400

Greetings to all

Im having difficulties deciding witch CPU to get. Im going to use it with Asus P5Q-E mbo and kingmax 800mhz rams.

On the one hand i like the brute performance of the E8400, since it has very good OC potential , but, thinking in the future, quad 8400 may be a good choice also.

Tell you the truth im not using my PC professionally, only what i need is speed in every day jobs (including new and upcoming games ) and stability

Please write your comments on this...

thanx

Q8400 is what i recommend dude.or you can even look out to Amd Phenom II X2 550 where u can unlock other two cores and make it a Quad core.

for the price of theq8400 you could get the ph2 945

Reply to obsidian86

Guys i would rather go in intel

Reply to Pantera-N

If I were you, I would buy Q6700. In UK Q6700 has the same price with Q8400. I know is old and is on 65nm but FSB 1066 make them much better for OC and have bigger cache memory.
If you didn't buy the motherboard yet, I would suggest AMD.

Q6700 is not avaliable in my country.

Only

If its just mostly gaming and general usage then of the 2 you picked - E8400.

With that said, if you really want a quad, then seriously consider the PhenomII 9x0 line. They get performance on par with Intel's top end Q9x50 processor.

A Q8400 will generally net you the same gaming experience as using an E5x00.

i think you are exaggerating a little bit. Common, Q8400 the same with E5x00???

Believe me, I'm not exaggerating. Core2 Quads are really just 2x Core2 Dual, on the same processor package.

Q9x50 = E8x00
Q94xx = E7x00
Q8x00 = E5200, E6300

this is the Q8200 and E8400 comparation

looks to me that the performance is very close

core 2 quads are just 2 core 2 duo's on the same chip

Reply to obsidian86

i know that but you said that Q8400 has the same performance in games like E5x00

i have that hard to belive

Reply to Pantera-N

If your game only uses two cores and those two cores have the same spec as an E5200, well you can work out the rest.

ok then , how about Q9400?

Reply to Pantera-N

A Q9550 is the one to go for if you can stretch to it.

$169 for Q9550 if you live near a Microcenter.

Ahh, that changes things slightly. CC purchase from a UK site perhaps?

Reply to Mousemonkey

no, customs fees are to great , the Q9400 it the top price i can go

Reply to Pantera-N

I think the E8400 would be your faster option. go Quad when a lot more software actually makes use of them.

Reply to Mousemonkey

get a quad if you multitask , or do any of the following :

play far cry 2
play gta4
( note those are the only games that i know that use quads)
work with 3d programs (rendering) programs
video production programs
animation programs
image editing program
virtual machines

that's all i can think of right now .

Reply to demonnn

I would like to see some evidence that gta4 utilizes quadcores.

I would pick up the E8400 and a good cpu fan for a solid overclock of 4ghz+

Go for an AMD triple or quad core. I've had four intel dual cores and eight 775 motherboards because the intel chipset kept f@#king up or suffered from voltage drop and wouldn't boot. I went to an AMD quad at the end of last year and haven't looked back. It's so much better in game play than the dual core intels and a lot more reliable.

Actually COD4 and COD5 are optomised for quad cores and will use 5 of the cores in my dual socket Opteron. If I had a more powerful graphics card it would most likely use more cores.

Reply to Malcolmk

I7 drops 12fps from 1280x1024 to 1068x1050
E8600 drops 2fps from 1280x1024 to 1068x1050

I guess it does use quads....now if they will patch it to take advantage of high-end GPUs and SLI.

I would still like to see benchmarks with higher resolutions.....say 1920x1200 (what I game at)

Reply to Snowbum

Just to add this to the equation

the prices for E8400 and Q9400, here in Croatia are identical

Reply to Pantera-N

E8400

------------------------------ E8500 @ 3.8 (Normal settings)
E8500 @ 4.5 (Benchmarking settings)
Reply to werxen

That's got to be the best compromise, only 400mhz off clock speed wise.

I have Socket 775 e8400 build I keep around for a 2nd or spare PC. The mobo is a GA-P43-ES3G. I scan for Core 2 Quad CPU, the Q8400 is the lowest priced but I would not call that reasonable. Do you have any leads? The e8400 remains in PC til I locate a fire-sale Core 2 Quad. Maybe Q9505? When I review " CPU-Benchmark" I wonder why I would invest anymore into the Socket 775. By the way, I am a video trans-coder with a i7-950 Build, w/ 6Gb ( 3x2Gb ) 1333Mhz, GTX460 336 stream processors, SSD, HX750, Blu-Writer and Zalman 1000+. After all that , I find the i7-2500 outruns me. It doesn't matter because blu media is @ 2x,4x, & 6x with best quality copies in @ 1x. Sorry, did you sport any low priced Core 2 Quads?
