I currently have the Intel 630 and might sell it for the 805 (because...apparently it is better) however I need to confirm from you guys that it actually IS better. I want it to be "evaluated" from you guys in an overall aspect. Without overclocking this CPU is better than mine, right? I say this because it is a dual-core CPU. With overclocking, this CPU has potential, am I right? This CPU is cheaper than mine!!! How come? Does it have less cash memory? Is it missing Hyper-Threading? I mean like what is going on here? Bassically...what is the catch??! *edit* I just found out that the 805 has 2x 1 mb of cache...which I know it's not calculated like this but I will still calculate it like this (1 mb + 1mb=2 mb) the other thing that concerns me about that CPU is...is the FSB speed 533 Mhz? (instead of 800 Mhz compared to the 630) I just got one question about my mo-bo (ASUS P5GDC Deluxe), is it limited to 533 Mhz FSB? I say this because the max clock speed of DDR2 Ram it supports is 533 Mhz! So...am I right? If so, then that means, my 630 is working at 533 Mhz bus speed (excuse me if I am wrong..I barely know anything bout bus speeds..I think). I still can't decide which CPU is better...I think it is the 805 but something is wrong!..that CPU IS cheaper! (which is why, I started this thread)
If I was to give a performance rating of the old "is like a xxx mhz" style, I'd rate the 3.0 Prescott at about 2800 and the D805 at two lots of 2400. In a single threaded app (some conversion programs, gaming etc.) the Prescott will be faster than the Smithfield 805, but if you're running a dual-core app (some DVD encoders and winRAR) then it should be up to 70% faster. The D805 overclocks very well, but gets very hot if you do so.
I just went from the same P4 you have to a Pentium D 930. I don't think I would go through the headache just to move up to the 805. Just my opinion. You are looking at a motherboard change as well if you don't have the 945 chipset or greater. I just went through a huge headache upgrading mine. I guess it was worth the headache in my case. I did it to improve video encoding which in the program I use went from 45fps to 65fps. I don't think you would notice a difference like this going to the 805. Oh, I had to upgrade to DDR2 memory as well as the board I bought didn't support DDR.
It is a pain, and yes you do need a late chipset to support the D805. In all reality, I'd either set your sights higher or wait until you can get something better.
I learned a bit from here: http://www.legionhardware.com/document.php?id=548 and thanks for the extra "talking". I ask because I can sell my used 630 (installation included for the person who buys it which is another reason why someone would buy it) for the same price of a new 805! So...I am going to upgrade for free. I just want to know this. With the 805, I can achieve almost the same gaming performance as a 630 and be able to run Apps like Adobe Premiere Pro in the backround? (Assuming RAM is not important because I can go up to 4 GB) That CPU (805) DOES work on my mo-bo, right (ASUS P5GDC Deluxe)? Can someone explain a bit more about FSB to me, I am bit lost in this area.
That seems like a good article, but if you want my advice, I'd say the 630's better at gaming, but the 805 is going to be able to run things in the background, and also process dual-core apps a lot faster.
Is it true that if cooling is not the problem (imagine I live in Antartica) that the 805 can overclock more than the 630? I am a gamer but I am also a very, very, very heavy multitasker. Just to browse the net, I need a more powerful PC than the one I have since I have demanding apps like system mechanic running in the backround. Bassically if price is also not of the concern, which one is better, period? I guess ultimately it is, if you are a gamer more than a multitasker, you will get a slightly better performance with the 630 and if you are a heavy multitasker more than a gamer, you will get a better performance with the 805. Back to the Antartica "issue"...how many fans would one need in order to keep the heat of a 805 down if overclocked at its maximum capabilities. Why is FSB important (if it is important)? How does that make the 805 lose points? Isn't it true that in the future, games will be "dual-core apps"? Bottom Line: If all cooling material is acquired, can a overclocked [to its limit] 805 beat the 630 [overclocked to its limit] in the Ghz area? Assuming that once again, all the cooling material is acquired, what does the 630 [overclocked to its limit] have in power (of any sort) that the 805 [overclocked to its limit] doesnt?
yes it is, a 630 is only good for 3.6-3.8, an 805 if cooled properly will hit 4.0. If you multitask, dual core is an absolute necessity. Front side bus being low is technically good because you can make it 800mhz versus 533, and have your chip overclocked 50%, to 4.0. higher FSBs can't go far enough before they're well above the 1Ghz mark, which is a nono for stability. Games aren't ever going to become dual core apps really, only singles, so 4x4 is the only dual core tech beneficial to gamers. Bottom Line: an 805 OCed to it's limit can beat the 630 at the same task, mhz for mhz, speed for speed, task for task.
I was looking at ure mobo specs on asus it clearly says pentium 4 and no sign of suport for pentium d 805 so where did u hear that? and just because the pentium d is socket 775 and ure mobo is 775 doesnt mean theyre compatible
It would probably need a BIOS flash, but after that it should work. I assumed, probably wrongly, that s3a knew about that.
I assumed with a Bios upgrade that it would work. Plus, I have asked many people in comp stores about it. I never got straight answers BUT the smart ones told me that after the Bios upgrade, dual-core CPU's (Socket 775, from Intel) should work.
And I'd say they should too. Dunno how much weight on the situation I have! I have to admit you're doing well for 14. When I was 14, I had a store upgrade my PC (just to fit an HDD and GPU!) and they said "I'd reocommend this" to which I replied "yeah, sounds good". 21 months later - "I'd like to buy a 40GB Maxtor diamondmax plus 8 please". yeah they're not all that good but I was looking for a cheap OS HDD as an interim at that point. Now is a further 27 months down the line... how time flies!
LOL! A role model, any more flattering going to occur? I'm glad you see me that way, but why specifically me, of all the other helpful souls here at aD?
There will be more flattering! Sammorris, it's just a matter of time. I respect all the other "helpful souls" but they just cant be compared to you! I have one more question. You have told me that the Intel 805 can beat the 630 in every single way if cooling was not of the concern BUT how much cooling would I need exacly and how many Ghz can the 805 reach OC'ed to it's limit??! Is 5 fans enough? If you count the "built-in" fans it's 7-8 fans. Gfx card's fan, CPU fan, and PSU fan are examples of "built-in" fans. Right now, I only installed 2 of my 5 fans! Is there any way (maybe a program) that allows me to check CPU/Gfx Card temperature in Windows and not in Bios?! How hot should the CPU and Gfx be? In other words, what amount of heat should they not surpass??! Tell me in both Farenheit and Celsius. I am more concerned with the CPU's heat. I will not OC it one bit but when the time comes and I need to, I have no choice! Is there a way to OC only one of it's cores? That's creativity (if it doesn't exist)! I ask because, that way, it diminushes heat and allow me to play high-end games with it's first core and second core can handle windows tasks!
A D805 will reach 4Ghz if you use all premium gear and tweak things to perfection. Realistically aim for 3.6 or so Ghz. The number of fans is relatively unimportant, it's the airflow and where that airflow is going. In at the front, out at the back, in at the side, out at the top seems to be the idea, however, numerous cases like exhausting air out the side. The most important things to have are a good OCing mobo, such as a P5LD2 (yours may well be good enough though), a good, stable PSU and a meaty cooler, a Zalman CNPS9500 seems to be the order of the day. Asus PC probe for Asus boards allows to check temperatures in Windows. CPU, System and Hard disks. ATiTool allows you to check the temperature of your video card. Your CPU should never exceed 65C(149F), as beyond that it'll throttle back and slow down anyway. The GPU should never really exceed 75-80C(167-176F). Last time I checked you couldn't just overclock one core, the process just doesn't work like that, but you can reduce heat by only using one of the cores... My X2 will manage 36-37C idle, 43-45C with one core 100%, and about 50C with both 100%. Heat isn't too much of a problem stock, but stock the D805 is a slower processor. There are two of them which helps, but mhz for mhz, MIPS per MIPS, GFLOPS for GFLOPS, the 630 is faster per application.
A CPU has never surpassed 3.8 Ghz without overclocking so...I think that 4 Ghz will last for a very, very long time! If they don't make that 350 Ghz CPU! It's scheduled to be out in 2 years to the public! Anyway my questionable/point is: An App will not require over 3.8 Ghz for a very, very long time meaning that the 805 is a much better choice! I DO need the 805 because, I multitask sooo much that the 630 can't handle it!! It's soooo slow!! I need to be able to run a game on one core and windows stuff on the other core. I am in bad money situations right now but when I get out of this situation, I will buy another GB of ram to enable the dual-channel plus to add another GB! I might also consider getting a SATA drive. Is it true that the faster the HDD, the faster things like windows boot up? Does it speed up performance? I ask because WD Raptors do, or so I've heard. The HDD I am considering to buy is a Seagate, 320 GB, SATA, 16 MB Cache, 7200 RPM! Will that increase my system performance??! My current internal HDD is a Western Digital, 80 GB, 7200 RPM, 2 MB Cache, PATA HDD. Thanks in advance!
The extra HDD cache will make a small difference, but only 16MB cache drives and Raptors really give you extra boot performance. All that new drive will really give you is more space. I'd be willing to take bets that 350Ghz CPU isn't out in two years time, probably not even five.
That SATA HDD I might buy will speed up transfers as well, right? Instead of taking 2 min to transfer a GB of data, it will take like 50 seconds! Right?
ROFL not quite! Might shave a couple of seconds off, but that'd be it. If you want silly fast transfers, maybe you should look into RAID. On second thoughts perhaps not, it's quite complex and has annoyed me quite greatly. I can go into that if you like, but I won't waste 3 paragraphs!
