HP ProDesk 400 G3 Desktop-Mini-PC - change processor?

[evenpar]

Hi there,

the HP ProDesk 400 G3 Desktop-Mini-PC (1EX82EA#ABD) comes with an Intel i5 7500T. I would like to use a i7 7700T or better.

The computer is only used for office work, no gaming or video at all. But since a month I use Dragon Professional Individual 15 (speech recognition) all day and this program needs a lot of computing power.

Can someone confirm that this or other processors will also work?

Thank you for your help,

kind regards

Klaus

Hi, this should not be a problem. You would want to use a CPU with the same TDP as your current which is 35W.

Here is a list of the CPUs you can use:

I guess you could also opt for a better i7 if you replace your power supply. The mother board seems very similar. For now Intel Core i7-7700T should work as you suggest. I would also replace the thermal paste with a better one like Noctua or take a look here: https://www.gamingscan.com/best-thermal-paste/

The Intel Core i7-7700T is pretty expensive even used. It is almost half the cost of your ProDesk! But let me know if you go on with this and the results.

Thank you!

I'm still using the original processor since I could already buy the Intel® Core™ i7-8700T  which may even be stronger. But I have not decided anything jet because as you said - it would be almost half the cost of the system. And I think I would need new memory.

My ProDesk 400 G1 came with an i7 4770 CPU. 

It benchmarks much faster your CPU and surprisingly close to the i7 7700T.

Might be a cheaper option to consider.

> I think I would need new memory.

Why?  If you keep the same motherboard, you can keep the same RAM.

Installing faster RAM would only improve performance if the motherboard supported faster RAM.

If your motherboard does, maybe faster RAM is a less-expensive performance-boost than a faster processor.

From: Quick Specs

the motherboard:    Supports DDR4 memory up to 2400 MT/s data rate

for some processors,  and up to 2133 MT/s data rate

for some processors.

So, faster RAM will give up to 12.5% improvement.  Is that good "bang-for-the-buck"?

Are you already using a SSD, for maximum Input/Output speed?

I thought the i7 4770 is socket LGA1150 which also supports 5th gen. Intel CPU. the 7700 T is socket LGA1151 which also supports 6th and 7th gen. but not 8th (Coffe Lake) which although has the same socket is a completetly different chipset. Am I wrong?
