• There was a huge difference in the 1% lows, with the 7800X3D having a minimum of 52 FPS, while the 245K was about half as stable with a minimum of 27 FPS.

A Plague Tale: Requiem

• Testing these chips with A Plague Tale: Requiem, we saw the 7800X3D had an average framerate of 178 FPS, which was about 48% higher than the 120 FPS of the 245K.
• The minimum framerates were around 73 FPS with the 245K, which was around 74% lower than the 127 FPS we saw with the Ryzen 7 7800X3D.

Hitman 3

• The last game of our testing had an average framerate of 268 FPS on the 7800X3D, whereas the Core Ultra 5 245K hovered around 232 FPS in Hitman 3, marking the 245K as about 15% faster.
• The minimum framerates were around 238 FPS on the Ryzen, which was once again 15% higher than the 206 FPS that the 245K managed.

Productivity Benchmarks

Now that we’ve taken a look at the gaming benchmarks of these processors, we will see how they compare against each other in terms of productivity benchmarks. These tests were done with the same test bench as we used in the gaming tests.

Cinebench R24

• In the single-bench Cinebench tests, the 245K pulled ahead with a score of 137 points, whereas the 7800X3D got a score closer to around 120 points. This difference computes to around 14%.
• The multi-core score was also higher on the 245K, with a score of 1522 points. It led the 7800X3D by around 36%, with the Ryzen getting around 1115 points.

7-Zip 

• In the compression part of this test, the 7800X3D pulled behind with a score of 124 points, while the 245K was around 8% faster with a score of 134 points.
• The decompression tests ran around 11% faster on the Ryzen, where we saw a score of 134 points, while the Core Ultra had a score of about 121 points.

Photoshop

• The Pudget systems benchmark ran a bit better on the Ryzen 7 7800X3D, which was about 5% faster than the Core Ultra 5 245K in our testing. 
• The Intel chip got a score of 10465 points, whereas the AMD chip got around 10984 points.

Overall Performance

Average Framerate

The difference we saw between these chips was remarkable when it came to the average framerates. The Ryzen 7 7800X3D was about 30% faster than the 245K on average in our tests, with the difference shooting up close to 50% in some games. The 7800X3D consistently beat the Core Ultra in all the games we tested.

1% Lows

The minimum framerates were no better. The 7800X3D ran these games about 32% better than the 245K when it came to the 1% lows, which made a night and day difference in some of the games like Homeworld 3. The 7800X3D was consistently remarkably faster than the Core Ultra.

Productivity

The overall win in productivity goes to the Core Ultra 5 245K in our testing. The 7800X3D was a bit faster in the 7-Zip decompression test as well as the Photoshop test, but it did not add up too much. However, GPU-bound tasks might run better on the 7800X3D because of the extra headroom it clears.

Power Consumption 

When we tested the power consumption of these chips, we saw that the Ryzen 7 7800X3D took about 22% less power than the Core Ultra 5 245K, which is remarkable as the Intel chip already barely sips power. AMD has continued to impress with the power consumption of the X3D chips with this processor.

Temperatures

The temperatures were barely different between these two chips, with the 7800X3D being about 3% cooler than the Core Ultra 5 245K. Overall, temperatures were very manageable on both processors and should not be seen as a pivotable deciding factor between these chips.

Price And Value

The Core Ultra 5 245K was released at a lower price than the 7800X3D, and the recent changes in the price of both these chips have kept a sizeable difference between them. As of late December 2024, the Ryzen 7 7800X3D costs around 43% more than the 245K.

Our Recommendation

Core Ultra 5 245K: To be honest, we weren’t sold on this chip while making this comparison, but the price painted it in a new light. This chip did drag behind in the gaming tests, but there might be a difference you might notice at 1440p and 4k gaming if you choose to use this chip with a better GPU.

Ryzen 7 7800X3D: Though the price of this chip has not dropped significantly since its release, it still is one of the most powerful gaming processors on the planet while still being extremely efficient in terms of power consumption. The performance-per-watt of this chip is truly marvellous.

After all this discussion, we would recommend the Core Ultra 5 245K to people who want to build a low-budget build to play games at higher resolutions, while the 7800X3D takes the win in overall performance if you have the budget for it.
