Who cares if AMD has the fastest CPU or not when their chipsets are trash? Motherboards are important, and the main reason why I wouldn't even consider buying a Zen 4 CPU, at all. Intel has the best motherboards, and that's going to matter when you start to factor in cost to performance, and other considerations. CPU performance is not the only important metric the consumers are interested in. AMD doesn't seem to understand this. It's a good thing they've added an integrated GPU. What took them so long? However, their chipsets became a dumpster fire. So, I'm waiting for a time when AMD can truly compete with Intel, which they can't, right now. Well, perhaps if you're building a pure gaming rig which you don't plan on reassigning to server duty after it becomes obsolete. So, e-waste, basically.

Hi ! I really hope you gonna read this message. 7800X3D looks really nice in gaming but a lot of us (including me) dont have only one thing launched on their PC at the same time. I was wondering how it would perform during streaming compared to other X3D cpus with more cores, can the CPU divide X3D cores for a game and other for streaming and other apps ? How big the difference would be in performance. Or you know, sometimes I play Cyberpunk or other game and watch video on second monitor and other mix of tasks. Is there any chance you could ever do the test like that ? I still sometimes like to stream and Im looking to upgrade to one of these CPUs . Im just afraid 7800X3D will be lacking a lot behind others which have more cores to use for OBS and other apps running together with a game.

those frame time analysis should really be done on a synthetic benchmark IMHO, because real games have things like async texture streaming, decompression and other stuff going on which are very hard to control and replicate reliably. The results shown tell a lot of things about how well the game and engine code are doing but not too much about how well the CPU is doing, unless you are specifically testing for some CPU specific optimization like AVX or hardware video decoding. They are meant more as a debugging tool for game developers. For example the spike in cyberpunk at 12:32 is telling a story about some cpu intensive task that the game programmers could have (possibly) pre calculated in advance to the scene change bud didn't, resulting in a hitch frame.

PS
I would like to suggest some improvements for your charts as I find them difficult to read in the short timespan they are generally shown:
a) use a different color for the bar of the CPU/GPU/Case that you are currently reviewing, so that it is immediately clear where the product is in the chart
b) add a percentage metric to the right hand side of the chart so that the relative performance becomes more obvious, with the product in question as the benchmark/ reference point
c) add a color code for products in a similar price class/bracket at the moment of review so that it is clearer if more money actually equals more performance

I feel that they should have just released 7800x3d alone with high frequency, targeted at gaming, and let the the mainstream line be the best at productivity and an all rounder.
Now, we have 3 products with them performing neither here nor there and it just cannibalizes themselves and worse, make intel's offering looks more enticing considering the 13700 being a much better all rounder and not every game can take advantage of the additional cache.
I'm not too sure if that's a proper assessment but it's my first impression and even though 7800x3d is fast, I'm just really not impressed like how I was with the 5800x3d.

Honestly I don't think you guys went hard enough on AMD for kneecapping their own chip THIS hard. Like yes, its still a good chip, yes I know market segmentation. But just imagine how good this would be had its clocks not been scalped. I can't even say I think market segmentation justifies this either as this targets a different segement of the market than super high core count parts do anyway. In that way it's super dissappointing because it's very clear 'what could have been' but wasn't because AMD wants to push people to buy a more expensive chip suited for different tasks that they don't need.

24:14 I kind of disagree, maybe this CPU isn't great at productivity but it should still be more than usable. As a creator I don't think all core render perf is all that important for me and I'd rather have peak gaming performance while gaming or emulating while for render or in my case mostly just drawing I can just.. wait a bit more for tasks to finish and my apps are mostly single threaded anyway. AMD's long term platform support is a much bigger deal for me, that's why no Intel perf adventage is good enough for me to consider them over AMD
It's just my 2 cents tho, great review

Thank you for including frame time! As a VR enthusiast, it is a struggle to find frame times on these newly released CPUs. In VR, frame times can be the difference between an enjoyable experience or one that is unpleasant and can cause a bad time. An overall smooth frame time and lower frame times make a huge difference in VR and it's not talked about nearly enough. Even on high resolution HMDs, where even a 4090 is the bottleneck, CPU frame times can have huge impact on not only the games performance, but the overall enjoyment of the VR experience.

I'm not sure if the video actually address the clock speed other than around 4:40, although AMD do reduce 7800X3D clock speed, likely for segmentation, the difference is not 5GHz vs 5.7GHz. The actual CCD that has the V-Cache on 7950X3D can only boost up to 5.25GHz, thus not as dramatic as shown in the spec sheet. Say whatever you want, but the technical limitation prevent the V-Cache CCD to clock as high as the non V-Cache CCD. If AMD can clock the V-Cache CCD to 5.7GHz, they probably will clock 7800X3D at 5.5GHz (0.1GHz higher than 7700X).

There are powershell scripts to assign specific processes to specific cores. So you could move all OS threads to CCD 2, and leave Steam (and therefore all processes launched by it) to CCD 1.
I did this for a Zen2 system to improve minimum frame times. This isn t a consumer friendly solution but I remain curious if it works with the dual CCD 7000 X3D chips.
This also still lets those cores do stuff like OBS or whatever so there may even be practical benefits.

I think it's kinda cool that the CPU space is a lot like Mario Kart in which you can choose preferentially not just on brand but use cases.
Do a lot of gaming but a little bit of productivity? 7800x3D works.
Do a lot of productivity and a little bit of gaming? 13600k or 13700k has you covered.
You need a damn gun for gaming and productivity? 7950x3D.
You still need a damn gun but can't stop playing FFXIV and CSGO? 13900k is on the top left shelf.

I was excited about the 7800X3D as a drop-in upgrade to my 7700X ,but looking how much the frequencies are capped, it runs cool and efficient which means even PBO isn't going to help, adding to that the performance benefit of faster RAM on X3D cpu's isn't that great either. I think my 7700X with its -30 Curve Optimiser + highly tuned ram might actually still be on par in gaming or even better , no way for me to test though. I hope you can test that Steve!

As expected the reasons why AMD has only released a 5800X3D 8 core processor for gaming back in the day still apply for the Ryzen 7000 series. I really have a difficult time with AMD marketing claims, as if the (sometimes) fastest gaming CPU with the lowest power consumption in this performance class wouldn't be enough. Instead they want to hoodwink gamers by talking about cores, frequencies, and productivity performance that just isn't there.

You mentioned doing a fresh install for the 7800X3D cause of the driver issues causing bad results, do you think moving from the new AM5 7600X to the 7800X3D would need a fresh install as well or would it be fine once you update the Bios to allow for this chip and new 6000 CL memory ? I'm currently running stock Bios on the AM5 7600X, with 32gb of DDR5 5200 CL40 on the ASUS PRIME mobo. TY for any replies and help :D
Hope that made Sence :D

G'day Steve,
I liked the Frametime comparison chart dedicated to the 2 competing CPUs like you did here as it is something that is very relevant to good gaming & I don't think anyone else does,
As you try to stick to 30min unless you have time to fill in that 30min I think any more than 2 CPUs would be too much, because it would take away from something else just as important like Number of games or you final overview.
