Identical components but increased power consumption and greater thermal output.
Identical components but increased power consumption and greater thermal output.
I’m trying to understand this setup and it’s just an example with a few CPUs. You mentioned the Intel i9 7920X and 9920X, both have 12 cores. One has a TDP of 140W while the other is 165W, both running Skylake architecture from the 7th and 9th generations. My concern is whether they’re set to the same frequency and voltage—like 4.6GHz and 1.23V for both. If everything else stays constant, wouldn’t the 7920X actually cool better due to its lower TDP? The only difference seems to be the cache size: 19.25MB on the 9920X versus 16.50MB on the 7920X. What are the main benefits beyond just handling more heat?
Understanding TDP is quite challenging. These values rely on assumptions that aren't fully accurate.
TDP values aren't always reliable indicators. Intel seems to have misused them. How could both 9980XE and 9900X (18 and 10 cores) reach 165W TDP? The Skylake-X CPU would actually overheat more since its refresh rate is higher with soldered IHS, and more cache can boost performance in certain tasks.
Today TDP holds no significance; those figures are adjusted and optimized for promotional reasons and don't reflect actual values.
TDP offers a general sense of a cooler's capabilities for handling the processor, but it remains a rough estimate compared to actual usage. In some examples such as the 9900k, the difference can exceed two times what most users experience. To get accurate details, examine reviews that specifically measured CPU power use under different conditions.
