AMD to unveil Zen 4 CPUs at CES 2022

tbf, SAM being turned on doesn't change that they got top scores in Geekbench 5:
They claim this is fairly representative of single core performance (and therefore, gaming performance also).
AMD was behind in gaming after Alder Lake, they want to show that they've caught up. Either Golden Cove or Zen 4 should be more or less equal in gaming performance.

But it is built into the system and works out the box. You don't just switch a feature off cause the competition doesn't have it. Different RAM with different profiles affect it. It is a built in variable but you are comparing tech with what a user can expect at that moment in time and since you turn it on just like you would select XMP for Intel or EXPO now for AMD.
What's geekbench got to do with gaming though? A 12400F scores the same as a 5800X3D.tbf, SAM being turned on doesn't change that they got top scores in Geekbench 5:

Its a good job the majority of reviewers will test with the 3090ti then.
5600X and 5800X were enough to game on. The 7700X has ~800mhz higher boost clocks than the 5700X, about a 17% improvement. You need more?
I find it hard to believe that CPUs that can do 5ghz+ on all cores won't be enough.
The IPC improvements will vary, but the clockspeed is a definite improvement vs Zen 3. There's always Zen 4 V-cache, for those with the $$$$.
Edit- would be sweet if we could push the clocks to ~20% improvement vs the 5700X, that would require ~5.6ghz clocks on the 7700X...

It fine because I don't really look at any reviews generally anyways because I don't care what it's theoretical performance is at 720p using a 3090Ti is.
I want to know data of what I will get if I have a 3090Ti or 6900XT at 1440p and 4k gaming and what performance difference I will get with my actual gaming between say a 12900k, 5800x3D and 7950x. That is what actually matters to me, not epeen on what is fastest theoretically at a gaming situation that never occurs.
So I want SAM on, I would want RAM at fastest out of box settings (allowing for XMP & EXPO). If that means Intel has much faster RAM that is fine. It is what I want to know if I brought a PC and used it to game. True gaming experience. It isn't really a CPU review but I am not worried by that or GPU review.
Seeing data for the different CPU's with different GPUs at true gaming resolution and what out of box settings are then that is important.

You missed out one important word, I've added it to your quote in bold.
AMD Smart Access Memory optimizations for Death Stranding™ and Watch Dogs™: Legion: https://www.amd.com/en/support/kb/release-notes/rn-rad-win-22-5-2
- Up to 10% increase in performance with new SAM optimizations in Death Stranding™ @ 1440p Very High settings and up to 13% increase in performance with new SAM optimizations in Watch Dogs™: Legion, using AMD Software: Adrenalin Edition 22.5.2 on the Radeon RX 6950 XT, versus AMD Software: Adrenalin Edition 22.5.1
- Up to 12% increase in performance with new SAM optimizations in Death Stranding™ @ 1440p Very High settings and up to 24% increase in performance with new SAM optimizations in Watch Dogs™: Legion, using AMD Software: Adrenalin Edition 22.5.2 on the Radeon RX 6750 XT, versus AMD Software: Adrenalin Edition 22.5.1
- Up to 6% increase in performance with new SAM optimizations in Death Stranding™ @ 1440p Very High settings and up to 6% increase in performance with new SAM optimizations in Watch Dogs™: Legion, using AMD Software: Adrenalin Edition 22.5.2 on the Radeon RX 6650 XT, versus AMD Software: Adrenalin Edition 22.5.1
You'll need a AMD CPU and GPU to use SAM. Intel CPUs can use Rebar instead, and should still have access to the performance optimisations that go into AMD GPU driver releases.
So in short, I don't believe that SAM/ReBar will have any meaningful impact on the CPU performance for either side.
I doubt there will be much difference at those resolutions though until you get a stronger GPU, if your focus is gaming though then anything but a 7800X3D would be a waste of cash as the 3DX looks like it'll be a gen ahead for gaming with the current Zen 4 only matching the 5800X3D.

This is a fair summary. Buying one of these for primarily gaming makes little sense.
Also jufes/framechasers is wrong. It’s not running 1:1 fclk:mclk at 6000mhz

Gaming is one half. Revit, AutoCAD, Lumion Rendering and such is the second half but the figures with SAM on are not something the production slides/percentage shown used so for gaming slides of discussion using SAM then that is relevant. For workloads otherwise then it is of no benefit and doesn't do anything and not an issue for that.
So you either look at all those chips and consider SAM for the gaming results because that is what SAM does or if you are not bothered by gaming you don't need to care that SAM was used at all then.
Edit: So I go back to wanting the gaming known for those CPUs and how they compare with what they give with tools out box and with what GPU to pick to game at the resolution I game at and I want to know the production side for Revit/AutoCAD. So I would be likely looking to get something like a 7950x/12900k/13900k because I use my PC for both workloads.
We have Intel data too
It looks like 7950x beat Intel in this benchmark in single and multi unless the 13900k is unlocked, using the 350w unlocked power profile the 13900k beats the stock 7950x
Purported 5.7 GHz Intel Core i9-13900K Spotted at Geekbench
Raptor Lake chip boosted as high as 5.7 GHz during the tests.
* 7950x stock AMD claimed Geekbench ST: 2175points
* 13900k stock: 2133 points
* 13900k overclocked: 2314 points
* 12900k stock: 2040 points

They look good, nice to have competitive CPUs from both camps. Certainly not going to matter which brand you have, both are going to be stonking.

AMD Ryzen 9 7950X trades blows with the Intel Core i9-13900K in Geekbench's single and multi-core tests
The AMD Ryzen 9 7950X has finally made its Geekbench debut with a single-core score of 2,217 and a multi-core score of 24,396. Its main competitor, the Intel Core i9-13900K scored 2,169 and 24,189 in the same test.

Indeed. Good competition! Hopefully it comes down to them both competing on price.

It will be on for Intel too. And it works just as well for Intel. So 'meh'
The thing is right now Intel are talking to motherboard vendors about having ReBar on by default because their GPU's don't work properly with it off....
Anyway yes.... he acts like the sort of guy whose angry AMD are competitive, like he's yearning for the good old days of Bulldozer.

Fastest theoretical performance at 720p means that the cpu will last you longer, since it wont be bottlenecking your future graphics card at the resolution you are currently playing at. Say 2 cpus are similar at 1440p but one 30% faster in 720p so..
There is this too and wasn't it 2275 for the 7950x?

oh wow so close if thats the case and building new system will go AMD socket support will be longer nice option to have open
wonder what can be done with PBO looking forward to seeing it played with - Status
