Upgrade Opitplex 9020 SFF from i5-4570 to i7-4790?

Hi,

I have the Optiplex 9020 SFF which came with i5-4570. Can i upgrade the cpu to i7-4790? i'm not using any graphic cards just the built-in HD 4600. I have seen some Optiplex 9020s with i7-4790 online like this one:

Is it doable?

Thanks

According to the 9020 spec sheet - Intel® 4th generation Core™ i7/i5 Quad Core (84W for MT & SFF).

Also, the answer is yes.  I checked it against userbenchmark.

It is doable but you will want the "S" version of the chip due to 65W TDP

On a machine this old, most people are just happy that it's still working and 100% reliable . I know I would not be messing with it very much ... just use it as is.

Also, that SFF case/form-factor is not doing you any favors.

Sure, but why bother? The i5 is already a quad-core, so all you're really upgrading is a bit of MHz for the i7, which is not even close to worth the time, effort and money.

If you're not moving from a dual-core to a quad-core with HT, and can get at *least* a 100% performance increase, then it's never worth it and I doubt you'd even notice after upgrading a measly 400 MHz. No CPU upgrade is ever worth it, but this one isn't even close.

I might consider 6 yrs. old ancient for a computer if it weren't so widely available as refurb and used + parts + many people & businesses still using them from that generation.  Whether it be my healthcare provider, Walmart pharmacy, the public library, etc., I get to see Dell's in use almost everywhere.  6 yrs. old might seem long ago to somebody younger or can possibly afford a new computer every 2-3 yrs.; I don't know.

"It's old, get a new computer," as an answer did get old on some.  (Not meant to single anybody out.)  Then the petitioner would say something to the effect of "I know, but how about an answer to my original question?"  At least in this case, that was answered.

If someone is looking for new, they'd have to buy a Precision (or other) instead of Optiplex if they want it to take the hardware Optiplex's (namely the MT) used to take.  At least the Precision's can take much better GPU's.

Typically, when people come to this forum, they're looking for support for the PC they have.  Even if it's a 380 and not much can he done with it, we can still answer their question.

With economies that vary around the world, I'm sure viewpoints of what's old, new, or in between can vary.  Please remember out of warranty Dell's (but sometimes not limited to) is just what this forum is for.

Hi @Rico55,

An I7-4790S would give a 70% increase in performance according to game-debate.  Ultimately, it's up to you if you want to upgade the CPU.  Something I might agree with Da_Vinman on - I don't know how much of a noticeable difference that would be since you already have a quad.

I'm sure you can find a better deal on eBay, but the I7-4790S is still a little pricey.

Also, an 84% increase in performance for the non-S version, which has a TDP of 84 watts, which is still within the limits.

I7's have better braggging rights.

Thats why the 1151 now has I9's

Wrong CPU, that's a dual-core T version of the i5.

He's going from a "i5-4570 to i7-4790" - both are quads.

But people are not saying that, they're actually saying:

"Don't waste money on a CPU upgrade, instead save that money you would have spent and use it in a new PC later"

I have upgraded a *lot* of computers and it goes like this in terms of value, performance and effectiveness:

SSD -> GPU -> Memory -> CPU

And believe me, I know the allure of a CPU upgrade when you're running an older, slower PC - it calls out to you with wild promises of increased performance that will turbo-charge your old system, but it's a false god offering spurious promises that never turn out to be true. Most times, you won't even notice it. The fastest CPUs, even the older ones, are always the most expensive (because people inevitably get suckered) and you'll end up wasting a lot of money that could have been put towards a newer PC.

In one thread, a guy wanted to upgrade to an i7 2-series for $170 off eBay, when Dell was selling entire refurb i5-4-series quad systems (8GB + 500GB HD  or128GB SSD) for $140-$175 (after 40% sale).

That kind of foolish spending gets real old with me, real fast.
