it will be fun to see what they do, how they react to Zen 3.

Two things they (and Intel) can do
- promoting Rocket Lake months before release. RL is legit strong 8 core and below, plus AVX512
- focussing more on price/performance

So please, explain the tangible real world benefits of the 5800x having 100mhz higher base clock and 1x CCX vs the 5900.

Base clock doesn't matter.
1x CCX might, in special cases. Double size L3 might, in very special cases.
What will matter is boost clocks. 5900x higher sustained clocks due to power being spread over two chiplets? Maybe the opposite, each core on a single 5800x chiplet has more power budget so would boost higher?
Need to wait for benchmarks, and really in-depth ones. Which sort of conflicts with Thursday F5 fest...
If you wait to know for sure, you'll be waiting weeks for them to come back in stock.

Enjoy your 5900X mate. ;)

So basically, you can't explain to everyone reading why 100mhz and 2x CCX is such a big real-world benefit on the Zen3 5800x vs the 5900x? Right, got it. :)

Yes, I know full well that base clock doesn't matter that's why I was somewhat rhetorically asking old_school_gamer to clarify. The CCX latency issue is also greatly reduced in the "zero bubble" (AMD's name for it) Zen3 architecture. https://www.itworldcanada.com/artic...ries-processors-and-zen-3-architecture/436996

AMD’s Zen 3 architecture continues to improve on Zen 2’s modular design. In the previous generation, AMD’s Ryzen 3000 series desktop processors used multiple core chiplet dies (CCD) consisting of two 4-core compute core complexes (CCX) connected over the Infinity Fabric Interconnect. Each CCX had its own, separate 16MB cache. With Zen 3, AMD has unified the pools of cache into a single 32MB pool, thus decreasing latency and increasing resource sharing across the cores.

AMD has also reworked the front to back operation stack, including widening the integer and floating-point execution units (EU), load/storage operations, and the branch predictor. AMD also announced a feature called “Zero Bubble” that hides latency, a major roadblock of previous generations of Zen architectures.

There will almost certainly be no tangible real-world performance impact in the vast majority of gaming and productivity use cases, hence why AMD are doing all of their presentation testing and benchmarks on the 5900x.

The Old School Gamer doesn't really seem to know what he is talking about on these particular topics... although he was right about the ASUS 3080 TUF apparently which is clearly a big thing!

Mem isn't tuned all the way yet. He was tight on time and will tune it more tonight and re run.

Is that an all-core OC? Judging from multicore scores being way higher than anything currently in db (31-32k range)
If so, 4.7 all cores at 1.248V is impressive
 
I mainly focus on GB SC scores and how they’re derived. It’s beating my 9900k soundly in all key metrics that impact gaming: int, fp and mem.

Once the mem is tuned more and with higher binned chips you might be looking at 7000 SC score.

For reference my 9900k at 5.2core 4.8 uncore and 17/4600 mem gets 6120.

Are you intending to go from OC 9900K to 5600X?
Click to expand...

Probably a 5800x or 5900x. Need to see which has more OC headroom and whether IF is binned better on the dual chiplet models.

Ideally would like a 2000mhz IF with a C14/4000 1T config and setup a staggered boost on cores for daily but we'll see.

My current mem kit is good and can do 14/4000 on my 9900k and we know the IMC on zen is very strong already.
 
I would shoot for 1.3v on that puppy, maybe even a little more, my 3600 runs 1.375v at high load stock, 1.45v in low loads, they are on the same 7nm node.

Get it whacked up man.... they are built for it.

lol aint my score.

Oh... shame, pushed just a little harder and you would be the new Single Threaded score Honours winner. I think some of the first Zen 3 posts in there will do that easily. Scores over 650 are going to land in there thick and fast. its currently set for 625.
