Pros: -Fast -Cheap - Support MSI B450 Tomahawk Non Max -SAM is enable on B450

Cons: -Not delivered by Lisa Su herself

Overall Review: I upgraded from a 2600 with MSI B450 Tomahawk non Max. Flash the new Bios and it work perfectly out of the box. SAM was added into the bios feature so anyone with a B450/470 don't need to spend extra $$ on a new motherboard. The most impressive feature about this chip is their PBO 2 which undervolt and overclock as good as manually overclocking. The PBO that is feature in the Ryzen 5000 series are a lot better than the 3000 series according to various sources in google search lol. Highly recommend for anyone with older Zen and are looking to upgrade.

Pros: After swapping from a 1600x, around 60/70% improvement

Cons: Nothing so far

Overall Review: If you are below a 3000 series, go for it

Overall Review: For those lucky enough to snag an AMD Ryzen 5000 series CPU right now at MSRP please check your bios version on your motherboard before first boot. First time I booted this up the motherboard wouldnt recognize the cpu. Luckily I had a 3600 to test the motherboard. It worked fine so I figured the bios hadnt been updated. I have the MSI X570 Unify for those that are curious and the bios version was from August of this year. Once I updated the bios everything ran fine. Hope this helps.

Pros: This is an amazing upgrade from my previous i7 3930k k build.16 Cores and 32 Threads of Awesome.Lighting fast boot time and handles everything you can throw at it with ease.

Cons: One of the more expensive options even at MSRP

Overall Review: 5950x is a high end processor with a lot of power. Loads and runs any application with ease. Load times are a thing of the past. Going from an old i7 to this monster 5950x was like going from a dial-up modem to 500 GB cable. Do you really need a 16 core 32 thread processor? Probably not.Do you want one, YES, YES YOU DO.

Pros: Boosts to 4.85ghz Improved frame times over 6700k in gaming

Cons: Runs a little warm, but was expected, idle between 35-40c with ambient 22c, using a large air cooler Hits 77-80c under load

Overall Review: Upgrading from a 6700k, this was a great upgrade, would recommend.

Pros: - Big upgrade over zen 2 - Compatible with b450 motherboards after Bios update.

Cons: - None so far.

Overall Review: - This the best CPU you can get for gaming right now. If you can find it in stock grab it as soon as you can, you won't be disappointed.

Pros: - Hits 4.95GhZ with Ryzen auto-OC software, using Corsair H100i at 60C - Civ 6 map load times are under 20 seconds - Hardly breaks a sweat for most of my applications, and throttles itself quite effectively

Cons: - Civ 6 multiplayer is still laggy thanks to other players running on potatoes (single player AI turn time is insanely fast, however) ^ Obviously this is not a real con of the CPU

Overall Review: This was my first AMD build after ~15 years of Intel. Upgraded from the 6600k, and this thing is incredible. I was lucky and got one within a four minute window on November 6 (day after launch) before they sold out again. I haven't really put it through a rigorous test yet, but I'm confident it will destroy whatever games and A/V applications I throw at it.

Pros: Fast!

Cons: None for me.

Overall Review: I dont see what the fuss about heat is. I have a corsair h100i and this thing hasn't been over 66c even under heavy load. I had the Ryzen 7 3700x and wanted the 5900 but this will do perfectly. No regrets.
