The combos aren't impressive. I mean a 7900gre is always available at $550 so it's paying retail for the gpu and the 370 for the cpu. Maybe the monitors are a good deal, but not the GPUs. It's all retail plus $370….

7900x3d is the better balanced by technical specifications.

Here's a very simplified rundown of the 3 big x3d CPUs

7800x3d - 8 Cores / 16 Threads all parked on x3D Cache
7900x3d - 12 Cores / 24 Threads, 6 Cores / 12 Threads parked on x3D cache (generally only these cores will be utilized for gaming), 6 Cores / 12 Threads not parked on x3D cache (suffers from latency, not generally used for gaming)
7950x3d - 16 Cores / 32 Threads, 8 Cores / 16 Threads parked on x3D cache, 8 Cores / 16 Threads not parked on x3D cache

Gaming performance - 7800x3d (8C/16T) ~ 7950x3d (8C/16T) > 7900x3d (6C/12T)
Production performance - 7950x3d (16C/32T) > 7900x3d (12C/24T) > 7800x3d (8C/16T)

barring that AMD's core scheduling bug got fixed. I believe the 7800x3d performed better than the 7950x3d even though there's no hardware reason it should. Same idea of the bug for Intel CPUs where disabling the E-cores increased performance as there was a bug where the slower E cores were utilized in gaming instead of faster P cores. Disabling E cores forced the games to use the better P cores and improved performance in video games.

Yeah there absolutely was no point in adding in the bundles.

Genuine question:

I play games (War Is Hell, Cities: Skylines, Far Cry, Valorant), but I also work in Solidworks, Chief Architect, & Inkscape. Which would provide the best balance?

For gaming alone 7800x3d is the best, don't buy 7900x3d as the vcache only has access to 6 cores, while on 7800x3d it has access to all 8 cores. Amd should have never made this cpu. unless they split it 8 core vcache/4 core non vcache. the way the split it was very dumb.

there is a reason why 7800x3d has been Amazon's best selling cpu for almost entire time it has been released.

Best balance would be the 7900X3D for your usage, assuming you spend significant amounts of time in Solidworks, etc. Here is a good review on how the 7900X3D stacks up in gaming: https://www.techspot.com/review/2...d-7950x3d/. Basically, outside of a few select games, it hangs pretty close to the 7800X3D and 7950X3D. Keep in mind also that the higher the resolution, the less CPU matters outside of sim/RTS games.

It's not dumb from a technical standpoint. Cutdown CCDs are due to yields and the process is good enough that CCDs bad enough to warrant being cut in half are nonexistent. This is clearly seen by the fact that there are no Zen 4 CPUs with a 4-core CCD.

The primary reason the 7900X3D didn't sell well was because the initial launch price of $600 made no sense when the 7950X3D was $700. With the 7900X3D price now essentially competing with the 7800X3D, the 7900X3D makes a lot of sense for the budget workstation that wants to also game.

So what if I want a light gaming, edit video, multitasking, and watch 4K video? 7950x3D?

Edit: nvm, gonna wait till June for AMD Zen 5 announcement and release date. Should be a lot cheaper following announcement.

People that automatically go to the 7800x3d for gaming aren't considering resolution and the titles your'e playing. At really high resolutions and upper tier settings on AAA games, even a 4080 (sometimes even a 4090) will be gpu limited long before the CPU. There's a reason why all the review sites use 1080p to show the differences between the chips.

If you're rocking a 4k monitor and play graphics intensive games, this chip is a far better proposition. You'll be negligibly slower in gaming versus the 7800x3d. We're talking 2-3% overall and no difference in some of the more intense titles. On the other hand, you'll be substantially faster than a 7800x3d in things like encoding, rendering etc. I'm honestly shocked how many people don't consider these gpu bottlenecks.

https://www.techpowerup.com/revie...3d/21.html

4k gaming resuts with a 4090 ^^^. The plain jane 7900x is within 5% of the 7800x3d. The delta is even less with a 7900x3d. The delta shrinks further and further the with lesser gpu's.

Am I crazy or did you just link an entire test bed that does not include this processor anywhere on it?

Here's a comparison that actually has this CPU on it and compares it directly with the 7800x3d and 7950x3d at current price points since the main complaint on the 7900x3d previously was price vs performance not actually performance.
