Works great but condition is questionable upon arrival
The box was slightly damaged on the outside when I received it. It was still sticker sealed but when I opened the box, part of the plastic was broken and the pieces were at the bottom. Noticed one bent pin on the cpu but other than that it has worked great so far.

5.0 out of 5 stars you DO need a good heatsink to release the full power of this monster.
Reviewed in Canada on July 1, 2024
Verified Purchase
I’m currently using a mid-range air-cooled heatsink. I’ve noticed that this CPU heats up to 90°C under continuous stress, subsequently throttling its speed to safeguard the CPU. This has only occurred so far during performance tests. I plan to invest in a better cooler in the future to fully unleash this beast’s potential.
Overall, amazing CPU. Salute to AMD!

Upgraded from 5800x to 5900x, for future proofing and extending my AM4 platform for as long as possible. I do video editing in DaVinci Resolve mostly, and the 5800x was perfectly fine. Upgraded from 32Gb to 64Gb RAM also. Cinebench R23 gave me the expected increase in performance, scoring 19899 in multithread, and the CPU temperatures stabilized at 65c, with a double tower air cooler, the Peerless Assassin, with a standard MX4 thermal paste. Very satisfied.

5.0 out of 5 stars How Many Cores Does One Need?
Reviewed in Canada on April 15, 2022
Verified Purchase
The question was: How many cores does one need?
The answer is: As many as you can afford.

This is my first venture into the world of AMD. I've always been a tried and true Intel supporter but things have changed in the computer world since my last build almost 9 years ago. It seems AMD is now the king of the hill. After doing some research it was clear to me that I needed to have the Ryzen 5900x. I installed the CPU into an MSI X570s Tomahawk board with 64gb DDR4 3200 RAM and an RTX 3060ti. This processor is a beast. The speed at which it works amazes me. Video efiting, game play, everything else. It just does it without hesitation.

I had no issues installing it into my motherboard. My Arctic Feeze II 360 keeps it unbearably cool and so far it is tackling anything I toss at it. Great CPU.

Ótimo desempenho, mas prepare-se para comprar um bom kit de refrigeração pois esquenta que é uma churrasqueira, outro ponto é que se você utiliza-lo em conjunto com um Water-Cooler provavelmente terá de ter uma refrigeração EXCEPCIONAL nas VRMs pois elas irão sofrer com o alto consumo de corrente que o processador terá pelo Boost em tempo excessivo.

This is an absolute beast of a CPU.

I bought this to upgrade my B450 system from a Ryzen 5 2600.

First thing I did was check my boards compatibility with this chip, luckily, the BIOS was quite a lot newer than when support was added, so I didn't need to do any updates. If you do though, make sure you do it before you install this CPU.

I, really, didn't think I'd feel that big of a performance improvement. Boy was I wrong...

I put the CPU into "eco mode" through the BIOS (it was under AMD Overclocking on my ASUS Prime B450 board), as I'm only using a Noctua NH-U12S as a cooler. I plan to eventually get a more capable cooler, but this is working just fine, CPU is peaking out at 65C in eco mode with the single tower Noctua, pretty impressive if you ask me.

My Ryzen 5 2600 ran around the same temps under load, and idled in the 40s, this idles a bit higher, but it doesn't really get much warmer than idle from what I can tell, at least with my system configuration.

While I was removing my previous CPU it was actually "stuck" to the cooler. It actually popped right out of the socket... at first I was a bit worried that I may have accidentally broken something but... i apparently got very lucky. No pins were damaged on the old CPU, and it booted up fine in another system I tested it in.

New CPU installation was very easy, just line up the triangle to the corner on the socket with a triangle, after opening the clamp bar of course. The clamp bar easily went back into place, and held the new CPU just fine. *Whew*

At first I thought I may have damaged the motherboard, but... I took this as a chance to do a good cleaning of the inside of my case, and when I put the system back together... I forgot to plug in the GPU power cable *doh*. After plugging that back in, the system rebooted about 1000 times (got to love ASUS boards!), and then asked me if I wanted to overwrite the fTPM settings. I did, I run Linux and I don't use the fTPM. If you're running Windows 11, you may want to go through whatever procedure you need to go through to save this. You'll need it. You need to do this while your old CPU is installed though, or you'll have to go through the whole process of putting it back in if you don't! Luckily, I didn't need to, but be aware of this.

After wiping the fTPM settings and a few thousand more reboots (exaggerating a bit, it was probably 10 total, ASUS boards really like to do that), I was presented with a screen that said a new CPU was detected, and that all BIOS settings were cleared. Cool! So far so good!

I spent some time going through and reenabling my RAM speed profile (got to make full use of the 128GB of 3200MHz RAM I installed yesterday!), turning virtualization back on, and enabling eco mode (I didn't want to get a new cooler right now if I could get away with it). Enabling eco mode did bring the CPU temp down about 10 degrees in the BIOS, and from reading around the internet, doesn't really seem to impact performance *that* much. Easier than fiddling with undervolting settings I'd say...

After finally getting booted back up into my OS... I was actually kind of impressed already. Just from the increase in boot speed alone I already knew this was going to be good. It wasn't *slow* on my 2600 at all, it's still a very capable chip, but wow, this blows it out of the water.

I've been working on a rust project lately, it compiles in about... 45-55 seconds on my 2600... I did the same project compile on the 5900X? 6 seconds. Even in eco mode. Wow oh mighty. The power of 6 more cores and a dozen more threads.

I also run a Windows VM for several income producing applications (y'know, we all got to work, otherwise we can't buy these fancy new pieces of sand we send lightning through), and wow. Oh boy wow. Like I said, the 2600 wasn't *slow* by any stretch of the imagination, but the responsiveness and speed now is just absolutely incredible. The VM boots so much faster, every application is up and running almost instantly... and that's with only 6 cores dedicated to it...

If you've got an older AM4 system. Buy this. Buy this before they stop making them. Buy this, and upgrade your BIOS if you need to. Just get it. Seriously. This is a monumental leap in performance that will *absolutely* extend the life of your AM4 system by several years. This is *far* cheaper than building a new AM5/DDR5 system, and you will be absolutely blown away by the performance increase.

For $350 as of the time of this writing... it's worth every penny. Best performance upgrade I've ever made, for sure.

**Value for Money:** 5/5

The AMD Ryzen 9 5900X is an absolute powerhouse of a processor, and its value for money is unmatched. I was blown away by the performance boost it brought to my system compared to my previous Ryzen 2600X.

**Great Delivery by Amazon:** 5/5

Kudos to Amazon for their lightning-fast delivery! My processor arrived in perfect condition and within the estimated time frame, which is always a plus.

**Performance:** 5/5

The Ryzen 9 5900X is a beast of a processor. Idle CPU usage was reduced from around 10% on my previous processor to an astonishing 1-2%. This means that your system will be even more efficient and quiet when not in use. In terms of actual performance, I noticed significant frame rates and render times improvements in gaming and content creation.

**Heat Management:** 4/5

While the Ryzen 9 5900X is incredibly powerful, it does generate a bit more heat than expected. I saw temperatures ranging from around 55°C to 60°C during idle periods. If you plan on using this processor for heavy workloads or gaming sessions, I highly recommend investing in a quality CPU cooler to keep things running smoothly.

**Important Note:**

It's worth noting that the Ryzen 9 5900X does not come with a CPU fan included (I used an Evo cooler). This is mentioned in the product description, so be sure to factor this into your overall cost and planning.

In conclusion, the AMD Ryzen 9 5900X is an excellent choice for those seeking a powerful processor without breaking the bank. With great performance, efficient idle usage, and fast delivery from Amazon, it's hard not to recommend this product. Just keep in mind that you may need to invest in additional cooling solutions for optimal performance.

**Rating:** 4.5/5

I would definitely purchase this processor again and recommend it to others seeking a high-performance CPU.
