Amazing CPU. I paid the great price of £360 for it too, so really happy with purchase.
Fantastic purchase. Got it for my working PC, which I use for code compilation. Upgraded from 3300x and the difference is incredible. Running on a cheapo itx x470nh (which only has a 4-pin CPU power socket and it runs perfectly fine at 4.2GHz all day long. I haven't tried higher at this point, as I'm running it in an ITX case on a basic AMD fan, so I don't want to push it. To my surprise, it appears to run cooler than another 3600x that I used to also own, so am very happy with my purchase. It has improved my productivity each day, and it's also allowed me to be more focused at work, since code compilations are almost instant, and allow me to keep my train of thought, rather than getting side-tracked by other stuff whilst I'm waiting for basic tasks to finish. I'd recommend this to anyone needing a cheapish performant CPU for productivity work. It's fantastic. Read full review...

Awesome
Boost to 4.95Ghz out of the box, which is nice. Games? No problem. Productivity? No problem? It does need to be paired with a solid cooler as it can run hot. With the NZXT X63 (280mm AIO) my max temp has been 74C during extended gaming, so you can probably get away with a little less cooling performance and still keep it under 90C. I haven't run bench marks and I don't intend to overclock, so I am not sure how much thermal/power head room there is for overclocking. Overall a great product if you're looking for a top tier CPU but want to save a few bucks off the 5950X. Read full review...

Stunning speed
This processor is stunningly fast, both in single-core or highly threaded workloads. It often has several cores running at above 4.9GHz when running programs that require only a few cores.
Even when running an app that stretches all cores, like Cinebench, it can usually have several cores running at over 4GHz whilst the rest run closer to the stated base frequency.
Indeed, it is possible to run something like Cinebench in the background and be able to use your computer for tasks like word processing without any noticeable slowdown at all! I am yet to experience a workload that makes my Ryzen 9 5900x rig feel anything other than really snappy.
When compared to a Ryzen 9 3900x it runs single core workloads in excess of 20% faster. Multicore performance is similarly faster.
A couple of points; this processor is serious overkill for a gaming rig. Games just won't use all the cores or threads. A gaming rig will obiously be fast enough with a 6 or 8 core Ryzen; you just don't need 12 cores unless you are seriously into workstation-style workloads that require heavy multithreaded processing power.
If you are doing this sort of workload, you may think a 16 core Ryzen 9 5950X should be your first choice. Maybe. It is a lot more expensive and you would have to have serious HPC requirements to justify the extra expenditure. This cpu is a content creators dream!
Furthermore, I would suggest is that you invest in a quality heatsink. If you use the heatsink that comes with the Ryzen 3000 series, the Spirit Wraith, it will be very loud, run very hot and not be able to run at its maximum speed. I have attached pictures of the rather large Be Quiet heatsink that I use inside my computer.
With a decent heatsink it'll run quickly, but stay cool and so prolong it's life. Make sure you use a decent thermal compound between the processor and heatsink. I recommend Arctic Silver 5.
Pair this with some fast memory, an NVMe PCIe 4.0 SSD and a decent RTX 30x graphics card and you'll have the workstation you've always dreamed of owning. Nothing slows it down! I admit I purchased the game Control to test out my RTX 3080 and it looks amazing in 4k, whilst the cpu never breaks into sweat!
According to Geekbench this has a single core speed in excess of, and (obviously) running multicore workloads massively outperforms, an Apple M1 (according to the benchmarks I've run on my systems, with native M1 apps on the Mac). What more could a Windows 10 user ask for from a processor?😉Read full review...

AMD Ryzen 3900x to Ryzen 5900X, the last AM4 upgrade
This is a suitable replacement for the Ryzen 3900x which I have been using for the last few years. My thinking behind the purchase is that it would be the best and last processor produced by AMD for the AM4 platform before the upgrade path changes to AM5 or even AM6 if looking 3-4 years ahead. Installation is simple if you've done it before, just make sure that the BIOS is up to date before making the change over, other than that it's plug and play. I would say there is an improvement in speed around 15-20% for the image editing and manipulation that I do, so a worthwhile uplift when dealing with such large files produced by top of range cameras these days.

Works well
Was a bit sceptical (to say the least) about an unboxed, new cpu, but took a risk and bought it anyway. Works perfectly at stock speeds, even when pressure testing. Haven’t tried overclocking yet. Probably won’t bother as it’s really fast anywayRead full review...

My RYZEN system gets better and better
RYZEN systems are so easy to upgrade. Start with something modest and upgrade as you get the money to do so. You can put together a very modest RYZEN system core (MoBo, CPU and RAM) for £150 with parts off ebay. Then buy more RAM when you can, get the next RYZEN in the range when you can, all whilst keeping the same motherboard. Then you can upgrade the motherboard whilst keeping the same RAM and CPU. That gets you to the 5000 series CPU. Sell your old parts on ebay to support the next upgrade.
My RYZEN started with RYZEN 3 1200 and 8GB RAM and steadily made it's way to what it is today; RYZEN 9 5900X with 64GB RAM.
I'm pretty much at the top now, the 5950X is the final one which I may go for.
If you compare that with any Intel upgrade path and you'd be switching motherboards with most CPU upgrades putting the cost up hugely. Plus it's very confusing compared to AM4.Read full review...

Great processor!
Fast, reliable and runs cool on 240mm Corsair liquid cooler.
Was considering this or 5800x3D but decided this is better choice overall.

I got the Power!
Amazing cpu,I installed it very easily and it's made my PC very much faster than than I expected especially when multitasking or
gaming, faster starting is great as well, 1 would recommend this cpu to anyone who has a compatible motherboard and as always check the cpu support list for your motherboard Read full review...

Absolute a killer with a very good price/ performance ratio.
Absolute a killer with a very good price/ performance ratio. Very close performance to my 5950x, and I am quite confident that it can allow us to stay in the game for a few more years. Cheers.
