Energy consumption is one ofThe most important characteristics of modern processors. The release of thermal energy during operation presents certain requirements for the removal of excess heat. The TDP (Thermal Design Power) characteristic defines the minimum required heat dissipation for normal processor operation. Each manufacturer calculates TDP with different methods. This indicator cannot be directly correlated with the actual energy consumption of the processor.
Recently on Twitter the famous enthusiast underAPISAK (@TUM_APISAK) posted a link to the SiSoftware benchmark test results for the latest 10th generation Intel Core chips (Comet Lake-S). APISAK has published research data on the Core i9-10900T, i9-10900 and i3-10100.
According to Intel's classification, processorsmarked "T" belong to the models with low energy consumption and a TDP of 35 watts. Reducing energy consumption is provided by reducing the nominal frequency and voltage of the processor. So, when testing the Core i9-10900T, the maximum frequency did not exceed 4.49 GHz, while the actual energy consumption was 123 W at a TDP of 35 W. Previously, the Core i7-10700KF processor on the same benchmark with a TDP of 125 W showed a power consumption result of 250 watts. We can assume that SiSoftware was wrong in determining the energy consumption, which often happens with engineering samples.
The 10-core Core i9-10900T processor in SiSoftware showed 178.14 GOPS, which can be compared with the test of the 6-core Core i5-9600K chip, which received 196.81 GOPS in a similar test.
The same energy consumption, according to SiSoftware testing, was achieved for the standard i3-10100 processor (TDP 65 W) operating at a frequency of 4.3 GHz.
According to information received from insiders,The presentation of the 10th generation Intel Core processors with LGA1200 sockets will be held between June 13 and 26, but further development of the coronavirus pandemic may delay the timing.
