Does the substantially smaller cache on the 7800X3D mean that the two higher end CPUs are splitting their cache to two separate groups of cores or some such?
As I understand it, the 7950X3D and 7900X3D both have 128 MB of L3; 64MB in core chiplet dies (CCDs ) and 64 MB on layered on top. I don’t pretend to understand how it works, but apparently its with something called TSV (through silicon via). I believe the difference between the 144 and 140 is just the 1 MB of L2 cache on each individual core (16 vs. 12). The 7800X3D has what I believe is a singular block of 96 MB 32 MB of L3 on die and 64 MB of 3DV cache to go with the 8 MB of L2.
I’m gonna have to learn way more about chiplet engineering than I expected when deciding between the 7800X3D and 7900X3D…
Hopefully someone will run benchmarks in ACC & MSFS while streaming. I’m not in any rush to upgrade, but I definitely plan to.
It looks like they will only have the stacked cache on one of two chiplets for the two higher end models.
If they can do thread scheduling well, they will definitely end up being faster. If it’s done poorly, they could end up being slower than the 7800X3D in some cases. I await MSFS fans’ ludicrously expensive head-to-head benchmarks.
I wonder if they can tap into some of the scheduler optimizations for that already being done for Intel’s efficiency cores?
MS has to rework the Windows 11 scheduler to accommodate these X3D chips.
Yeah, it’s a big question mark right now, and it’s not something AMD has direct control of.
I quickly glanced at the Flight Simulator 2020 benchmarks for the new $229 Ryzen 5 7600.
(7600 as opposed to 7600 X).
I have the 5600 X, and compared to that Flight Sim (44fps) gave them quite a bit better result about 57 fps on average, and the 7600X only gave about 59fps, so not that much better than the $70 cheaper 7600 without the X.
Btw, the 5800X3D has about 59fps in that benchmark. And I think given the cheaper motherboard and memory, the 5800X3D continues to be the best value CPU in gaming.
Cheaper memory and motherboard, but the cpu itself is $150 more expensive than the 7600x! So the real pice isn’t that different.
The non-X versions are being liked by reviewers. But I have noticed that price wise, they have increased the price of the X version, as to have more ‘gap’ between both version and then be able to put the non-X version as a higher price tag.
I got my 7600x for 290€ a few weeks ago, which is just 22€ more than the 7600!
edit: 2 weeks later…
Gotta love Amazon and their illogical prices

I mean… the ‘X’ is in Spanish. They may not have realized what they were doing.
5800x3D $300 at Microcenter…
4070Ti at MSRP too.

Certainly the best gaming CPU deal you’ll see for a very long time-- the 5000-series is being phased out so if you want one, now is the time.
4070ti is overpriced at MSRP, even though it’s the GPU I would buy right now if I was in the market.

I watch Slickdeals every day and it kills me to see all the Microcenter deals. I’m not driving two and a half hours to buy my computer parts! Grumble grumble.
Oh well, at least the cheaper AM5 motherboards are starting to come out and the non-X Ryzen 7000s are reviewing well. I think I’ve landed on going power efficient on my CPU this generation(Ryzen) so that I can justify going more power hungry with whatever GPU I end up choosing.
The irony is that the non-X 7000s are selling higher than the Xs right now. Lol.

B&H has the non-X at MSRP, with the X versions a bit higher than that

I’d certainly go for the X for a mere fifteen buckaroos. More than that, probably not.

Nice. My next upgrade will likely be one of the 7000 series X3D CPUs pending release and reviews in February.
