Why AMD is better? My opinon, short and sweet.


AMD or Intel? What CPU is really "better"? Is one really better than the other? There are a lot of opinions out there on this topic and many good arguments on both sides of the fence. So I decided to go ahead and put my humble opinion out there and explain why I think AMD is the better choice for gaming and general computing.

Now I am not going to get into a long technical review of AMD architecture vs Intel, a lot of techno babble, or any of that jargon. I am going to explain the real world reason why I always choose AMD over Intel each and every time I build a system.

Now don't get me wrong, I am not saying Intel makes "bad" processors, quite the contrary. I think Intel makes great products. I just like AMD more for the reasons I am about to cover below. So here it goes...

Price vs Quality:

One thing anyone can easily see is that if you take two comparable CPU's on a site such as Newegg, one AMD and one Intel, the AMD chips are most always much less expensive. So does this mean the AMD chips are of a lower quality than Intel? That could not be further from the truth.

I have been using AMD chips since the days of Socket 7 and not once has a single chip ever let me down, though in that same time I have had 2 Intel chips go bad, still not a bad track record considering. So from my own personal experience, both chips have about the same level of quality and longevity. So from a quality standpoint alone, does it not make more sense to buy the less expensive chip that is at the same level of quality as the more expensive one? I think so.

Price vs Performance:

This is by far one of the largest reasons I buy AMD over Intel. Often in the real world, you get what you pay for, thus items that cost less often are of a lower quality then other items of the same category. That is, of course, unless we are talking about AMD vs Intel.

So what about performance. This is where people often get defensive and fanboys on both sides will start a fact fight and defend their opinions quite aggressively. So I am going to simply put my own personal real world experiences to the test here and give you a breakdown of the results. You can take from it what you will.

Lets say you take two identical machines, one with an i7 or Core 2 Quad q9650 and an AMD Phenom II x4 965 Black Edition and set them up side by side. Where the only difference between the two is the CPU and the motherboard of course.

Now lets take any game on the market and play them side by side. I challenge anyone to be able to see any performance difference between the two games. It's simply not going to happen. Sure the i7 has more raw power than the Phenom II, but no where near enough to compensate for the fact the cheapest i7 costs almost $400 more than the Phenom II 965.

The thing is, without detailed benchmarks, the end user would not be able to see the difference in his games performance between the two processors. The game will run great on both platforms and the users "gaming experience" will be the same on both chips . So why on Earth would someone opt to pay an extra $400 when your not going to get $400 more worth of performance?

I know some people just like to be able to say they have the power even though they wont need it. There is nothing wrong with that at all. I am just not one of those people. So this is where the price vs performance ratio wins out for me.

Even in everyday computing tasks such as web surfing, business applications, flash games and animations, video editing, watching movies, DVD authoring, and so on. An AMD Phenom X2 or greater will not let you down. Now unless your going to be rendering the next Pixar film on your home computer, there is no need to drop $600-$1000 on a CPU alone.

The Black Edition:

You may have noticed I have a Phenom X2 550 Black Edition logo at the top of this entry, that would because I happen to have that CPU in use here at home, with one difference. I am running it as an X4 Quad Core at stock speeds. The AMD Phenom Black Edition CPU's are an overclocker's dream. The 550 Callisto is a powerful dual core CPU that, with a little luck, can be made into a quad core Deneb with the right motherboard and BIOS version. This is because the other two cores are there, they are just disabled.

Of course, not all can be unlocked to an X4, some can only get a 3rd core running stable making it an X3. Where as some are stuck on a dual core because both of the disabled cores are truly defective. However the success rates for getting a fully stable quad core out of this CPU are very high, up close to 90%.

My unlock was stable after 5 hours of Prime95 and tested while playing ArmA 2. It worked like a charm. There is one drawback to unlocking those extra cores though, you loose the ability to monitor your CPU temps. Most modern motherboards however have a sensor under the socket that can be used to "estimate" your CPU temperature, in Everest Ultimate Edition it shows up as "Aux". All you do is compare the actual core temperatures to the sensor under the socket, under load, before you unlock your CPU. Note the difference so when you do the unlock, you can use the motherboard sensor to get an idea as to the CPU's temperature. This is important since your CPU will run hotter since there will be an extra core or two in there producing heat. With the proper cooling this is not an issue tough.

So something better than stock cooling is highly recommended. The " Zalman 9700 CPU cooler" is my personal recommendation. If want to research how to try your own unlock, check out this AMD Phenom II Core Unlocking Guide over at Overclock.net, everything you need to know is there!

So why bring this up? Even if your not lucky enough to unlock any of the other cores, this CPU is still more than capable, with other good hardware, of running any games on the market today. If you can unlock an extra core or two, all the better. So for less than $100 you have a CPU that can perform on par with Intel chips that cost much more. Such as an i5 or E8500 or E8600. Again, side by side your not going to be able to tell the difference.

Closing:

So in a nut shell, in a price vs performance comparison, AMD will always win hands down for me. I will be more than happy to put my overclocked Phenom II 550 quad core up against an i5 or i7 any day in any game and dare anyone to be able to say it does not run on par with the more expensive Intel chip. As long as both systems have comparable hardware across the board anyone will be hard pressed to be able to tell the difference based on "real world" use alone.

Isn't that what it's all about anyway, real world use? Even for a hardcore gamer like myself, the Intel line of chips simply can not offer up performance over the AMD line that can justify the sometimes massive cost differences.

So why not save a lot of money, buy AMD, and then drop that extra money into other hardware for your system? Such as a better video card, motherboard, or RAM? I think a lot of people forget there is a lot more to a system than the CPU alone.

No Display, Continuous Short Beeps , All Fans Spin, No Keyboard Response on a P4GE-MX Motherboard

Troubleshooting this P4GE-MX motherboard is not as easy as one may think. I have encountered a lot of computer troubleshooting similar to the problem of having no display, continuous short beeps and with all the fans spinning. But as guided with the knowledge of beep code errors, continuous short beeps leads us to say that there is something wrong with the system board. Of course, we can't directly jump into conclusion that the motherboard is defective. I have taken detailed observation and verification before making such conclusion. See the text below how I did the troubleshooting procedure for this computer problem.




Date Fixed : September 26, 2010


Problem : No Display, Continuous Short Beeps , All Fans Spin, No Keyboard Response on a P4GE-MX Motherboard



Owner : City Livelihood and Home Industries Development Office
Motherboard : ASUS P4GE-MX, P4 2.4 Ghz
Operating System : XP / Ubuntu



Technician : Drokz



INTERVENING FACTOR :

- No Installation CD



OBSERVATIONS :

- All Fans spin
- No Display
- Continuous Short Beeps
- Keyboard will does not lit



TROUBLESHOOTING PROCEDURE :

*****Please turn off the AVR and unplug the power cord if you'll replace or test any peripheral in your computer system unit*****

- Before the troubleshooting was started, I asked a couple of questions to the students who has used and observed the behavior of the computer before it totally broke. So here are the following observations as said by the students.

Question :
- "What happened before the computer completely shuts down and never give a display again?"

Answers :
- "It keeps on freezing."
- "It won't restart if the restart button is pressed"

Question :
- "Did it only occur once?"

Answer :
- "It did a couple of times as we power it back. But on our fifth or sixth attempt trying to turn off (turning off the AVR) and turn on the system back again, it did not give any display but the fans still spin."

It must be noted that it freezes upon operation and could not be restarted using the restart button. We can speculate that the operating system is least to blame for this trouble. So there are six things to check for this problem. And we need to isolate each of our suspected troubles to screen off mistakes in troubleshooting.

Suspected troubles in the order of priority to check :

- Video Card (improper seating and fan speed)
- RAM
- Power Supply
- Hard Disk Drive
- Operating System
- Motherboard

- Please remember that we will be doing "Isolation Method" of troubleshooting. We will be testing each peripheral one after the other so be careful with power. Always turn off the AVR and unplug the power cord each time you swap a peripheral.

- Since there is an integrated vga port, we can use it instead of the video card. Upon removing and checking the video card for physical defects, we found none. So we proceeded with the checking by using the integrated vga port and turned on the system. But still there was no display but continuous short beeps. We also inserted the removed video card to the other computer system and found out that it just worked fine.

- Video defect has been eliminated. It's time to check the RAM. We simply swapped the existing RAm with a known good RAM from a running system unit. We also used one slot after the other and still got no display but continuously gives out the repeating short beeps again.

- RAM defect suspicion was also eliminated. Since stubborn computer problems like this is attributed by a defective Power Supply Unit (PSU), so the system's PSU MUST be checked. And as it was checked using a multimeter, the power output were ok. Not contented, I opened the PSU to see if there are blown or burnt capacitors on its board but has seen none. So I decided to swap it with a known good PSU then powered on the system. Again, there was no display but a continuous short beep.

- Suspicion on the PSU was again eliminated. So I switch my attention (a little attention) to the Hard Disk Drive and the Operating System. To check two things that are relative in one time. I decided to remove the Hard Drive immediately from the system unit then powered on the system unit. Again, there was no display but a constant repeating short beeps. It seems the solution will go no further. I have suspected the bios to have crashed. All of its peripheral just works fine. I even swapped the processor but still has no difference or changes.

- So I search for the documentation for Pheonix BIOS and found tons of documentation about the matter. The dreaded constant repeating short beep was an indication of a failed BIOS and the only way to fix it is to hot-swap. There was no way to flash it because there was no display and hot-swapping was the only solution. I cannot afford to hot-swap it with the other working system unit because it might end out having two computers broken and the training center had only 4 working computers. Too bad I can't perform such hot-swapping for the computer. But anyway, the computer didn't go to waste, it is now used by students to practice assembly and disassembly of the system unit.

- Problem not solved or was limited to solving it



SUMMARY

- It is good to note and check the beep errors given by a failing system unit. Just like a repeating short beep that indicates a BIOS problem. The troubleshooting should have not taken long enough to spot the cause of the problem. It is also noteworthy to check documentations on the CMOS manufacturer to confirm or verify your suspicions.
