Upgrading Your CPU – Conclusion(s)

Replacing or Upgrading Your CPU

When my Windows 7 upgrade disc arrived in the mail last week, it triggered in me an urge to do a more extravagant hardware upgrade to the machine I intended to install Win 7 on. 180px-High_Performance_RAMThis urge resulted in me pulling out the OEM RAM and the E2200 dual core CPU and installing 8 GB’s of matched pairs of high performance DDR2 RAM and a Q9550 Core 2 Quad.

A fairly significant “performance upgrade”.
* See Windows 7 64-bit Adventures and Pt 1, Replacing or Upgrading Your CPU

In parts 2 and 3 (Replacing or Upgrading Your CPU – Pt 2 and Upgrading the CPU pt3 – Selecting A Processor) I described the process for determining which processors will ‘fit’ and function on your machine, and then how to look at benchmark scores for the different CPU models.
That brings us up to date.

Now that you know what CPU’s to look at (and which won’t fit) you can look at and compare prices and benchmarks to find the right CPU deal for you. In my real life example, I happened to find the Q9550 for well under $200, and I was satisfied with its rankings on CPU performance charts.. The deal you find, and CPU you prefer, may very well vary (there are better CPU’s than the Q9550).

CPU “Factors”

| # of cores | Speed | Wattage | Performance |

Three of these processor “factors” — # of cores, clock speed, and “performance” — will be reflected in the benchmark scores, so you don’t need to study and become an expert on each of those. The general rule of “more is better” (typically) applies here.

But when considering a CPU replacement/upgrade, you also want to look at the processor’s Watts.. and one other factor I’ll get to in a moment.

1) Look up the Watts on your old processor.
In my RL example, an E2200, which is rated at 65W.
2) Look at the Watts on the processor type you’re considering.
In my RL example, a Q9550, which is rated at 95W. (Also, try to find “recommended power supplies for”, and make a note of the most mentioned Wattage.)
3) Look at the Watts on your PSU (power supply unit).
Now it’s time for a little math — I know, yippee.

Continuing on with my RL example, we can see that my new processor draws 30W more power than the old one: further research shows that the most frequently mention recommended PSU Wattage is 500W: and when I plug my system’s components into the eXtreme Power Supply Calculator (and allow 20% for capacitor aging) I get a result of minimum = 315W (which seems low).

My power supply happened to be rated at 500W, and so I felt I could do the upgrade without also upgrading my power supply. But you may need to, and that is an additional expense that you should factor into your thinking and your budget. (See question #2 here, for the how to)

Another “factor” for consideration is heat (and therefore, cooling). My processor will produce more heat (higher Wattage, more cores..) than its predecessor did, and so I downloaded and installed SpeedFan to better help me keep an eye on the temperatures inside my case. Heat is the enemy of electronics, and letting your chips get too hot will kill them.
So you may need to protect your investment by upgrading the cooling in your computer case as well.. and that is an additional expense that you should factor into your thinking and your budget.

In conclusion:
So there you have it. It only took me 4 articles to describe all the most relevant considerations for a hardware upgrade, and if you do all those things, you should have a pretty good idea of your own personal “upgrade path”.

I was lucky: I did not have to upgrade my power supply, and it appears I won’t have to upgrade my cooling. My upgrade – 8 GB’s of matching RAM and a quad-core CPU – cost me right around $300. It could have easily been more.

So my upgrade to 64-bit Windows 7 and high performance components turned my machine into a real speed demon, right? Well…
Several of my “Windows Experience” scores went from 5.2 to 7.5; and yes, my computer is a bit quicker and more responsive. I like how it behaves.

But, I liked it with the E2200 and the 3 GB’s nearly as well.

Currently, very few programs and games are written to take advantage of 64-bit, multiple processors, and multi-“threading”. Also, I have yet to put any load on it that could use the extra RAM. So, simply put, there is really very little noticeable “speed” improvement in my day-to-day usage… though there is some. (Games perform with less hesitation, but to really bump my fps, a graphics card upgrade would have been the proper “upgrade path”.)

Short version: I do not regret my upgrade, but I would not do this again; as my original equipment’s 5.2 scores (under Win7) were quite satisfactory. The E2200 is a much better CPU than its “low end” reputation had me thinking, and 3GB’s of RAM is enough in most cases.
To improve the performance of my aging gamer computer, I have decided against a hardware upgrade: I will pool my money and replace it with a new machine with the new “i7” architecture.. and donate the old one to charity.

Upgrading the CPU pt3 – Selecting A Processor

In the preceding articles in this series I described how receiving my copy of Windows 7 triggered in me the very geeky impulse to upgrade my machine’s hardware capabilities — to go along with my first (good) 64-bit OS. If you are new to this series of How To’s, please click the provided links and read the first two before reading further here.
1) Replacing or Upgrading Your CPU
2) Replacing or Upgrading Your CPU – Pt 2

In those articles, we established the three things we need to know before shopping for a processor (so that the CPU will fit and function), namely — Manufacturer/socket type/motherboard’s chipset. (The instructions for how to do that are in pt2.)

* In my RL case, that was: Intel/Socket 775/G33.
* In my hypothetical Pentium 4’s case, that was: Intel/Socket 775/915G

By consulting the chipset/CPU compatibility tables on the Intel website, we discover that the:
* G33 chipset can accommodate: pretty much any socket 775 processor.
* 915G chipset can accommodate: Pentium 4 (up to #672) and Celeron D (#351)
So that latter is a no go. I would reco forgetting an upgrade. Leave it as is and/or new machine is the way to go. So let’s keep going, but assume that we have a chipset more like the 33G — and we can choose from any of the Intel Socket 775 CPUs including the “Core” series duals and quads. OK?

Since I’m thinking quad-core, I see that there are more than a dozen “Core 2 Quads” to choose from (the Core 2 Extreme editions are too pricey for me) … and if I mix in “extreme” dual cores.. it’s a lot to pick from!

(AMD users will follow essentially the same steps but on the AMD website. AMD has a “wizard” to help you narrow down your search too, based on some answers you provide. Click here to see that. AMD has at least as many to choose from — Phenom vs Phenom II and X3 and X4 as well as different model #s.)

CPU “Factors”

| # of cores | Speed | Wattage | Performance |

There are a lot of CPU’s to choose from and it’s easy to get confused by all the specs. There are many websites that are dedicated to nothing but hardcore Geeks trying to squeeze the maximum performance from each and every component, and they have published many CPU comparisons (and tricks). Sometimes these Geeks call themselves “gamers”.. and they like the word “extreme” (a couple of clues for you, there).
There are also many reviews posted (sometimes.. conflicting).

sample_chrtI am going to save you some trouble. I am simply going to point you to two of my favorite sites which have CPU comparison charts which will look like the sample shown and tell you that the longer bars are better.

These are “standard” benchmark scores. (If you are thinking of overclocking, you can find benchmarks and scores for those too, but I don’t discuss OC-ing here. UltimateExtremeGamer.com is more the place for that.)

The two places I look for these scores are:
* Tom’s Hardware (in particular, the 3DMark Vantage 1.0.2 CPU)
* Passmark
I put Tom’s first because you really can “drill down” into CPU performance scores, as several different benchmarking tests are run, and videographers might decide on a different CPU than a gamer will (for example). Also, you can get a feel for pricing, and read reviews and recommendations there. Anyone considering an upgrade (of any kind) should make a stop at Tom’s.

Okay. That’s it for today. Go have fun looking at some charts. In Part 4 I will explain the “factors”, and how they will help you have a smooth installation of the CPU you decide to go with.
