Windows 7: Desktop comparison

Desktop comparison

I'm planning to buy a new desktop these days so I'm a bit confused if the new PC hardware will be any aster than the old.
I have my eye on a Dell 7020 which is sol with these specs core i5 3.3GHz 4Gig RAM 6G cache HD5 500Gig HD
Full specs are in the following link

Dell OptiPlex 7020 Specs - CNET


A HP Compaq dc7600 Pentium D Core two Due 3.4 Ghz 4GB Ram + Nvidia Geforce 9600GT display adapter

I'm going to increase the amount of RAM on my new Deskto as soon as I buy it (how much? that depends on the cost)

What I'm concerned about is the clock speed of my old processor is faster than the new

Thanks in advance for your advice

The first machine with the i5-4590 is considerably faster.

Clock speed by itself doesn't indicate much.

CPUs from different eras do different amounts of work for a given clock speed. The second machine is circa 8 year old technology. The i5-4590 was introduced in 2014 and is considerably quicker. It will also use less power and run cooler.

The i5-4590 scores over 7000 on the Passmark benchmark. The Pentium D 3.4 scores under 1000. That gives you an idea.

RAM: how much do you normally use? I have 4 GB and rarely use more than 3. The typical machine has 8 and rarely uses all of that.

It's unclear to me from your link if that Dell ships with 4 GB of RAM or 6 GB. I'd monitor RAM usage after I bought it and would NOT buy more unless I was using all I had.

Unused RAM won't make your machine faster. It's pointless to buy more than you'd actually use.

Few people can make a case for needing more than 8. Again: how much do you typically use with your current PC?

Get an SSD (solid state drive) with the new machine if at all possible. It will make a noticeable difference compared to standard hard drives. You could buy the machine with a standard hard drive and then add the SSD yourself afterwards if necessary. You'd keep Windows and applications on the SSD and keep your personal data files on the standard hard drive. Might cost 70 to 100 dollars for the SSD.

Thank you ignatzatsonic for the reply!
Yes I am planning on installing SSDs but I want to use the computer with the provided HD first so I can get the feel of increaed performance/ faster boot times when I put in the SSD(s)

Before Without X.M.P After With X.M.P not much of a difference but not bad considering it took 30 seconds to change in the bios, and its safe! :)

32 bit vs 64 bit Comparison
There are many, many threads on this one simple question: 32 bit or 64 bit Windows? Well, there are a few things to consider when making this choice. The most obvious difference between 32 bit and 64 bit is the amount of RAM the system can use. The limit on 32 bit is 4Gb of RAM, whereas a 64...
