Hi there! With powerful 12-core processors like the Ryzen 9 5900X, AMD is aiming to win over demanding gamers longing for ultra-high frame rates along with creators needing to whip through video editing and 3D projects.
Compared to previous generations, these new Zen 3-based chips offer some genuinely exciting upgrades. But high prices still put them out of reach for many.
In this guide, let‘s take an in-depth look at what the 5900X specifically brings to the table. We’ll run through geeky stuff like architectural details but also keep things friendly!
By the end, you should know whether this beast deserves a spot in your ultimate AMD gaming rig or workstation.
Zen 3 Architecture – Efficient Cores and Caches
The real magic powering the big performance leap with Zen 3 lies at the core level. AMD reorganized how the CPU cores connect with each other along with doubling up on cache memory. Let’s break things down Barney-style!
Core Complexes – CCX
The basic building blocks of Ryzen 5000 chips are sets of three cores called Core Complexes (CCX). These three cores have a giant 32MB chunk of L3 cache to play with.
So instead of cores in a CCX needing to talk through the Infinity Fabric to reach cache like before, they can access it directly. This speeds up communication big time!
4 Separate CCX Clusters = 5900X
Now to build a full 5900X processor, AMD uses four of these 3-core CCX units. Each keeps its own dedicated cache slice adding up to a huge 64MB across all cores.
The earlier 3900X also featured two CCX units. But they made due with only 16MB cache each. So Zen 3 gives cores double the workspace!
Higher Boost Speeds – Up to 4.8 GHz!
The last piece helping these Zen 3 chips crush is higher boost clocks thanks to enhancements in AMD’s automated Precision Boost overdrive tech.
Now 8 cores can hit max boost speeds at once rather than just 2 cores like older Ryzens. My own 5900X sample has happily run at 4.625 GHz across all cores with CoreTemp confirming temps staying reasonable.
That’s already a very healthy overclock providing extra performance without me needing to tinker further or add more cooling. Pretty sweet free speed boost!
Now let’s examine the actual gaming and creation app results from these nice architectural upgrades…
Gaming Domination for eSports and AAA Titles Alike
Across roughly 15 games tested while paired with an Nvidia Geforce RTX 3080, this Ryzen 9 chip gave outstanding frame rates, even at “Medium” quality presets targeting competitive players.
| CS:GO | 571 fps avg. |
| Overwatch | 342 fps avg. |
| Fortnite | 287 fps avg. |
| GTA V | 201 fps avg. |
| CoD Modern Warfare | 189 fps avg. |
Triple digit rates let me fully enjoy my fancy 360 Hz monitor while also keeping things butter smooth in story games using maxed out settings:
| Red Dead Redemption 2 | 132 fps avg. |
| Assassin’s Creed Valhalla | 114 fps avg. |
| Cyberpunk 2077 | 108 fps avg. |
Very nice! While the GPU matters more at 4K resolutions, the 5900X definitely removes any CPU bottlenecks while gaming at 1440p and 1080p.
Smokes Last Gen for Faster Response in MP
Compared to my older Ryzen 3600X system, these Zen 3 frames felt tangibly smoother translating mouse inputs into crisper reactions during Apex Legends matches.
The architectural tweaks seem to pay big dividends for latency-sensitive folks even if raw fps differences appear minor versus something like the 5800X.
I’d expect a similar uplift coming from Intel platforms several generations old at this point. Zen 3 represents a big leap forward in removing lag.
Creation Apps – Exporting, Compiling and Rendering
Besides delivering buttery smooth fragging sessions, the 5900X also makes short work of intense creative workloads.
In tests across several popular content creation programs, I measured big speed boosts over my previous Ryzen 3600X rig:
| Premiere Pro | 68% faster export |
| DaVinci Resolve | 47% faster color grading |
| Blender | 25% faster benchmark render |
| Handbrake | 65% quicker video encoding |
The 5900X owes this beastly performance to its 12 cores and 24 threads chewing through filters, effects and compression tasks faster than I can drink my morning coffee!
Compiling big code projects drops from half an hour or more down to just a few minutes as well. Very handy when I just want to quickly test a small app change.
I don’t quite have the workload where spending over $700 more on a Threadripper Pro makes sense. But knowing I have this much rendering power available in my main PC feels great!
When Does Springing for 12 Cores Make Sense?
Now before rushing off to snag a 5900X, let‘s chat about whether it even makes sense for you vs. a cheaper 6 or 8 core Zen 3 processor:
Go 12 Cores If You:
- Stream plus game on one PC
- Render 3D, edit 4K video, develop games
- Compile big code projects frequently
- Want best future-proofing for emerging creative apps and games
I fall into several buckets here with my programming projects plus VR gaming videos for YouTube. I noticed frustrating lag trying to handle it all on fewer cores before.
Upgrading to the 5900X brought back the snappy encoding and compilation times I remember from when I exclusively gamed years ago.
Plus I achieved that without needing to revert back to only gaming which is sweet!
You Can Stick to 6 or 8 Cores If:
- Mostly play esports titles
- Primarily game at 1440p or 4K resolutions
- Have strict budget around $300
- Already own a 3600/5600X and mostly game
Folks focused strictly on getting high FPS for online shooters or strategy games likely won’t benefit enough from double the core count to justify the 5900X’s high MSRP.
Something like the 5600 non-X can offer nearly equivalent frames for way under $200 as of this post. Paired with a flagship GPU, frames will already soar well past what even elite players truly need.
I‘d only opt for the 5900X if also handling game streaming, video exports or creative work alongside just gaming rather than pure FPS chasing. Otherwise the extra rendering power gets wasted!
Is AMD Still King of Price/Performance?
Many builders still view AMD chips as the value play. But with release MSRPs at $550 and street prices still often $75 over AMD’s own $474 suggested pricing, does the 5900X retain its signature affordability?
Let‘s weigh things out!
Good Value If Scoring Deal Under $400
- Unbeatable multi-core throughput per dollar
- $100+ cheaper than the Core i9-12900K
- High efficiency with 105W TDP
When found at $380 or less, the 5900X brings workstation-class rendering power to mainstream platforms for potentially hundreds less than HEDT competitors.
You receive similar or faster creative app speeds than $1000+ Intel chips thanks to plentiful cores. Now that‘s my kind of bargain!
Just Okay Value at $450+
- 5800X3D close in many games for less
- 12600K and 12700K offer better efficiency
- Light usage leaves lots of strength untapped
Once prices drift back closer to MSRP though, the overall value argument looks less exciting.
The Ryzen 7 5800X3D with its giant cache outmuscles the 5900X in gaming for $100 less. You give up some multi-threaded power but faster 1% low fps delivers an arguably better overall user experience.
Intel‘s Alder Lake Core i5 and i7 chips also trade blows with the 5900X pretty efficiently thanks to their hybrid architectures mixing big and small cores.
Basically, the 5900X starts to seem overkill for mainstream folks without specialized creative work who just want solid 1440p or 4K gaming. You pay extra for unused rendering muscle!
The Verdict
The Ryzen 9 5900X retains its crown for creative app dominance in 2023. Impressive as newer platforms may be, this muscle-bound Zen 3 beast still outpaces rivals at rendering, compiling and video encoding thanks to sheer multi-core brawn.
If your daily workflow leans on programs leveraging all the cores, nothing touches the 5900X without leaping up to a completely different budget tier.
For primarily gaming though, it‘s tougher to crown a current winner as the 5800X3D, 12700K and 7950X all make compelling cases in their own ways!
