The Core i9-12900K burned 60 more watts than the Core i9-11900K, despite the former's newer hybrid architecture and the more advanced Intel 7 process node used to manufacture the chips.Intel 13th Gen Raptor Lake iGPU Clock Boost Helps It Close In On AMD’s Vega Integrated Graphics #īenchleaks discovered an OpenCL test result on the Geekbench database which shows an Intel Core i9-13900’s OpenCL score.
While the Core i9-12900K is clearly a class-leading performer in the benchmarks, it does so at the expense of much higher load power. We can't say the same for the Core i9-12900K, though. The more modest 10-core Core i5-12600K, is downright power friendly relatively to the previous-gen despite outrunning the older flagship Core i9-11900K more often than not, the 12600K actually uses less power than the more mainstream 11th Gen Core i5-11600K.
Load power, when all cores are being fully utilized, however, is mixed. Relative to the older 11th Gen Core processors, idle and single-core power consumption is improved on the 12th Gen processors, which illustrates a clear per-core efficiency improvement with these new chips.
The power consumption stories for the Core i9-12900K and Core i5-12600K are quite different. We do, however, also want to share some additional information regarding frequencies and temperatures with the processors running in their stock configurations. We are going to experiment further with our test-bed and will update this section with more overclocking related info when we can. We did not have any instability to speak of, but when we made any tweaks the processor's multipliers, under sustained multi-threaded workloads (like Cinebench, for example), core temps would very quickly shoot up to 100☌ and the chip would throttle back down to what was effectively its stock performance level. Although these chips are unlocked and Intel has incorporated a handful of new overclocking-related features into them, we hit a wall with our particular setup and the Core i9-12900K. This is the point where we'd usually do a bit of overclocking to see what kind of additional performance we could wring from a new platform. The Intel UHD Graphics in new 12th Gen Core desktop processors is clearly a significant step up over the Intel UHD 750 in 11th Gen Core processors, but even with the increased bandwidth afforded by the platform's DDR5 memory, it can't quite keep pace with AMD's Radeon iGPUs.Ī Closer Look At 12th Gen Core Frequency, Power And Thermal Characteristics
