• The minimum framerates were about 7% higher on the Intel chip at around 206 FPS, while the 5800X3D hovered around 192 FPS.

Productivity Benchmarks

Now that we have taken a look at how these chips perform in gaming tests, the following few sections will focus on the productivity performance of the Core Ultra 7 245K vs Ryzen 7 5800X3D. The setup we used for these tests is the same as the one we used for the gaming benchmarks.

Cinebench

• The 245K had a single-core performance of only 137 points, which was about 44% higher than the 5800X3D’s 95 points.
• In the multi-core test, the 5800X3D got a total of 858 points, which was massively lower than the 1522 points that the Core Ultra had. This difference translates to a 77% lead for the Intel chip.

7-Zip

• In the compression test, the 5800X3D scored a total of 89 points, while the 245K had a performance of 134 points, leading to about a 50% lead.
• In the decompression test, the 5800X3D had a score of 116 points, which was only 4% lower than the 121 points that the 245K achieved.

Photoshop

• Finally, Photoshop also ran much better on the 245K. The Core Ultra was about 21% faster than the 5800X3D in this test.
• The Core Ultra 245K got a score of 10465 points in the Pudget systems test in Photoshop, while the 5800X3D got only 8638 points.

Overall Performance

Average Framerates

In the congregated average framerates, the 5800X3D came out ahead but only by a very small margin. The 5800X3D was only about 3% faster than the 245K, which is good news because it means Intel’s budget CPUs are catching up to the performance of the legendary first X3D chip.

1% Lows

The difference in the averages carried over almost one-to-one when it came to the lows, with the 5800X3D being ahead by only 3% as well. Though this is, once again, great for the Intel chip, it means that the 5800X3D has started to show its age.

Performance

As we expected, the 245K crushed it in these tests. It came out leaps and bounds ahead of the 5800X3D in all the tests we ran. The X3D chips weren’t ever known for their productivity performance, and these tests reminded us why this is.

Power Consumption

In our power consumption tests, the Ryzen 7 5800X3D came out ahead even though the Core Ultra had 2 extra years to catch up to this level of efficiency. This difference is small, though, with the 5800X3D only consuming about 7% less power than the Core Ultra 5 245K.

Temperatures

The Core Ultra ran about 4% hotter in our test, though both of these processors were completely in safe temperature ranges. Neither of these chips ran too hot in our testing, and we think these temperatures should not be factored into the buying decision because of their very low difference.

Price And Availability

Both these chips are about the same price at the moment, with the 5800X3D being only around 3% more expensive than the Core Ultra 5 245K. This makes us believe that the 245K is fairly priced, though it won’t be winning any bang-for-your-buck awards.

What We Recommend

Core Ultra 5 245K: After going through all these factors in this comparison, we can safely say that the Core Ultra 5 245K is not a bad deal. Yes, it only beats the 2-year-old chip in productivity and almost matches it in gaming, but for the benefits you get with the 245K being a new chip, it might be worth it for a lot of people.

Ryzen 7 5800X3D: The oldness of this chip is a marvel, as it still outperforms recent processors. It performed better in the gaming tests, the power consumption is still excellent, and the price has decreased to be passable in this day and age, though we’d still like to see it go down further.

The 245K is a close competitor to the 5800X3D in the gaming tests, while it massively outperforms it in productivity. From this, we can say that the 245K is the better deal, though you might be able to find a 5800X3D pretty cheap on the used market, in which case the tables turn.
