5.0 out of 5 stars Ryzen 9 7900X CPU - Excellent CPU for literally everything!
Reviewed in the United States on April 24, 2023
Been waiting to build my new rig for quite some time and this was the missing piece.

New build:
Corsair Icue 7000X Full Tower RGB
Ryzen 9 7900X CPU
32GB DDR5 5600 Corsair Dominator RAM
1 TB Crucial M.2 Gen 4
XFX Merc 319 Radeon 6950XT 16GB Graphics Card
Corsair 1000w PSU
Gigabyte X670 Elite AX AM5 Motherboard
Corsair iCUE H150i Elite LCD XT Liquid CPU Cooler (360 AIO mounted to top as Exhaust
6 Corsair ML140's Fans (10 total fans including those with the case/aio with 6 as intake and 4 for exhaust).
Lian Li Strimer V2 RGB Cables for the GPU and Motherboard (they look very nice and controllable via the L Connect 3 software)
As I needed additional powered USB headers I also added a Corsair Internal 4-Port USB 2.0 Hub - 4X 9-Pin USB 2.0 Ports for the Commander Core XT and Lian Li Controllers to function.
Thermal Grizzly Kryonaut Thermal Paste (removed the stock paste with AIO using TG cleaner wipes as well for better contact).
ThermalRight AMD5 CPU Shield - This allows the AIO or Waterblock (if doing a custom loop) to make WAY better contact with the CPU HS. It can be a little nerve wracking as your removing the cpu mount and installing this one but its worth it. As the AM5 CPU has no pins (the mobo now has the pins), its imperative you are gentle on the placement. Best way I found to install this shield was to place the CPU into the socket, then remove the cpu holder so this way you can't damage the cpu or pins as they are socketed. Installing the shield from that point is easy, just don't overtighten it. Theres a bunch of youtube videos on this process. Definitely recommend reviewing them before attempting this step.

I upgraded from my old Ryzen 5 2600X system with a GTX 960 SSC 4GB card and a 512gb M.2 Gen 2 drive.

Needless to say this was quite the upgrade from my old system.
Cinebench scores on my 2600X even with a mild overclock was only around 7200.

After getting everything configured/setup and Windows 11 Pro installed with all updates and enabling EXPO1 (RAM OC) and enabling SAM in the BIOS I started my benchmarking.

Cinebench score with just EXPO1 enabled baseline was 28745. What a jump!
CPU temp on the multi-core threading with the 360 AIO only went as high as 82c (AMD rates these to run at 95c as normal operating temp so it was well below even that).
Haven't done any OC'ing other than enabling EXPO1 yet since I really don't need to as the CPU and GPU run everything maxed out.

Tested on a few games on max/ultra settings and below are what I got FPS wise:

The Division 2 (All settings maxed and on DX12) - Avg 125fps on 3440 x 1440 165hz resolution
Aliens: Fireteam Elite - Avg 160fps on 3440 x 1440 165hz resolution
Borderlands 2 (older game I know but love to play it with max settings) - Avg 476fps on 3440 x 1440 165hz resolution
Forza Horizon 5 - Ultra Settings (max) including Ray Tracing - Avg 155fps on 3440 x 1440 165hz resolution
Aliens: Colonial Marines (older game) - Avg 190FPS on 3440 x 1440 165hz resolution
Warframe - Avg 155fps on 3440 x 1440 165hz resolution

Pairing this CPU and GPU together worked great and the CPU itself is a beast. It does get hot when it turbo's up into the 5ghz range which is why you need a really good cooler (either AIO or custom loop) to keep the temps in check.

If you do that, this CPU will be everything you need and then some.

One thing I always tell people is to take your time, plan out your PC parts you want for what you want the system to do (video editing, gaming, streaming, etc). Don't be afraid to look around for good deals. I scored the AIO Cooler off Newegg for a much cheaper price than Amazon had it and it works beautifully and the LCD screen is just a nice "geek" factor to put JPG's or GIF's there.

Once you have everything, take your time when building it. You may run into an issue here or there which is normal. First boot on AM5 systems is sometimes slow (Memory has to train) and you may see it cycle on/off for up to 1 minute. Mine did this and on the 4th power cycle it posted and I could get into the BIOS and everything showed up correctly.

Good luck enthusiasts and hope this review helped with anyone looking at this CPU for their system!
Its worth it!

I expected a lot from the Ryzen 9 7900X, but it honestly blew me away. It is superfast no matter what I do, and I use it as a workstation. Everything just goes, no lag, just smooth performance all around. I was surprised by how it stays cool and doesn’t suck up as much power as I thought it would.

A very great processor I upgraded all the way from a ryzen 5 5600g and let me tell you this thing smokes almost everything from last generation. I use it mostly for gaming and I am going to start streaming now that I have a better cpu I would definitely reccomend it if upgrading from last gen to am5

5.0 out of 5 stars Best-Value CPU on the market

If you missed the deals, my title might not be correct anymore, but for $384, this CPU offers amazing performance. While it's not an i9-14900KS CPU, it's still a great processor for high-end video editing, training artificial intelligence models, or even gaming and streaming.
I didn't want the X3D model because it cost a lot more and the 3D cache CPU came with a few disadvantages, but this CPU is amazing!

One more thing to mention: You'll have to clock your RAM at the maximum supported speed (5200MT/s), because that's what the CPU supports. I'm thinking of overclocking mine, but still trying to look through the warranty to figure out if I can still be under coverage.

This specific CPU doesn't really have great integrated graphics (my laptop can do better since it uses an "APU") but it can still run VALORANT on the lowest settings at 100-150fps with no discrete GPU without lagging. That's pretty impressive, and it can also run CapCut Video Editor pretty solidly too! If you want to build a new future-proof PC, I highly recommend this CPU.

5.0 out of 5 stars Excellent, fast multitasking; needs good cooling for intense operations

Here's my system build so that you have context: ASRock Steel Legend X670E motherboard, AMD Ryzen 9 7900X CPU, 2X32GB G.Skill Trident Z5 DDR5 6400 (F5-6400J3239G32GX2-TZ5RS), EVGA RTX 3080Ti, and CPU cooler beQuiet! Dark Rock 4 Pro. The system drives dual Dell Ultrasharp 27" 4K monitors. My goal for this system was easy yet intense multitasking and editing of very high resolution RAW photograph files. I could scarcely be more pleased with the results. The core clocks scale to system demands instantly and running multiple programs and monitor windows is effortless. Yeah, the CPU does run hotter than previous generations AMD 12-core/24-thread CPUs; but compare the thermal qualities to Intel's CPUs in this class! My CPU heatsink, even though running only one of its two included fans, has no problems keeping the CPU under 80C, even over sustained high system loads - and that, without being annoyingly loud. Low system loads typically produce CPU core temperatures of about 45C, with a CPU fan speed of 750RPM. I have no doubt I could drop the core temps under heavy load significantly just by adding the second CPU heatsink fan. My only negative comment here is that from purchase date to order delivery required a little over two weeks. Prime used to faster.
