Not too long ago,we examinedthe gaming performance of theCore i7-13700Kand compared it to the 7800X3D.
The Ryzen 7 processor was faster overall, offering 11% more performance on average at 1080p.
It made recommending the Intel processor solely for gaming very challenging.

Of course, there’s an even faster option from Intel that we’ll be examining today.
All said and done, the 13900K does cost a little over 40% more than the 13700K.
This cost difference is going to affect its value proposition versus the 7800X3D.
But enough preamble, let’s dive in.
Meanwhile, the 13700K was benchmarked using the MSI MPG Z790 Carbon Wi-Fi with DDR5-7200 memory.
As the Intel CPU supports higher clocked memory, we’re giving it every chance possible.
Then, for the graphics card, we naturally selected the Asus ROG StrixRTX 4090OC Edition.
The graphics card has been benchmarked at 1080p, 1440p, and 4K.
Previously, we found the 7800X3D to be just 8% faster than the 13700K at 1080p.
Similar margins are seen at 1440p before the results become entirely GPU limited at 4K.
However, the 1% lows of the 7800X3D do improve dramatically here.
Moving on toSpider-Man Remastered, we find that the 7800X3D and 13900K are neck and neck.
With ray tracing enabled, the 13900K and 7800X3D again find themselves neck and neck.
There’s just a few percentage points between them, so there’s no clear winner here.
In our opinion, the performance is close enough to call it a tie.
However, we’re talking about a mere 3% boost over the 7800X3D at 1080p.
Then, of course, we’re entirely GPU limited at 1440p and 4K.
That said, we do end up entirely GPU limited at 1440p with 160 fps.
Next, we haveHalo Infinite.
LikeFortnite, this is another game that’s largely GPU limited.
Whatever the case, both the 13900K and 7800X3D can get the most out of the RTX 4090.
As a result, even the 1080p data is GPU limited.
So, there’s not much more to report here, and we’ll move on…
This means that the 7800X3D is 7% faster, which isn’t a substantial margin.
By the time we hit 1440p, the game becomes entirely GPU limited.
The 1% lows were much the same.
The 13900K and 7800X3D allowed for an average of 123 fps.
Hitman 3 provides us with a similar set of results to The Callisto Protocol.
Shadow of the Tomb Raideris another CPU-heavy game, especially in the village section that we use for testing.
Next, we have Tom Clancy’s Rainbow Six Siege and a few notes on testing here.
The 13900K is a good bit faster than the 13700K here, boosting performance at 1080p by 11%.
The results from A Plague Tale: Requiem are also a bit unexpected.
These results aren’t useful at all.
Power Consumption
Let’s now talk power consumption and the methodology behind this measurement.
This reflects total system usage.
As with all of our testing, it’s stock, so just XMP or EXPO loaded.
The end result is typically much higher power usage for the13900Kwhen compared to the7800X3D.
Then we see some remarkably high power figures for the 13900K in The Last of Us Part 1.
Top Gaming CPU: AMD vs. Intel
So, there we have it.
That’s how theRyzen 7 7800X3DandCore i9-13900Kcompare head-to-head in terms of gaming performance and power consumption.
To tell the truth, they’re both very similar, as we noted in ourday one 7800X3D review.
It seems that the 7800X3D is generally faster when paired with DDR5-6000 CL30 memory versus the 13900K using DDR5-7200.
You’ll really want to research how the two compare for your workloads.
However, we should have an answer for you in around three months.
Until then, we hope you found this review useful.
