Replaced the temperature difference from 100 with a simple. Whats the difference between cpu and cpu packages, and why is it so high. Weve had a few great threads recently where members contacted amd and asked what temps they should. Big differences in cpu temperatures with different software for example ill take only 4 of them core temp, hw monitor, speed fan and speccy. Core temp is what amd refers to as tctl and is a nonphysical temperature on an arbitrary scale measured in degrees. Cpu temperature is measured by the onboard sensor chip onboard integrated on the motherboard pcb, while the core temperatures are measured by the cpu itself. I worked a bit with cuda, and a lot with the cpu, and im trying to understand what is the difference between the two. Theres also one difference between those values the core values are immediate, but the cpu package is an average of the last 256 ms samples. The case thermal diode measures tcase temperature case, which is cpu temperature, and the digital thermal sensors measure tjunction temperature junction, which is core temperature. Problem is when core temp and speed fan showing temp about 4050 c they both show same temperature at the same time and hw monitor with speccy show something between 95105 c same as well.
Tcase is cpu temperature measurement taken from the center of the cpus top surface heat spreader. Motherboard showing different cpu temp than cpu monitoring software. In the bios it shows the cpu is running between 40 and 50 degrees celsius. This temperature is measured by a diode embedded between the cpu cores. Core temp is a compact, no fuss, small footprint, yet powerful program to monitor processor temperature and other vital information. A core is usually the basic computation unit of the cpu it can run a single program context or multiple ones if it supports hardware threads. Delidded my first processor yesterday i5 3570 using a 3d printed delidding tool, link in.
Whereas other temperature monitoring software products stay the same for years on end, this one is continually being updated to fix bugs and add features. The core temperatures listed by many programs is based on a sensor that intel has. Do i trust cpu temp sensor or motherboard cpu temp. My q9550 reports similar differences in all 4 cores too, with 0 and 3 being the hottest, like yours. What is the difference between a core and a processor. Difference between processor and core can be a puzzling topic if you are not computer savvy. The most important temperature to measure in your computer is the processor, or cpu.
Speccy it analyzes nearly every aspect of the computer, from the cpu temperature to the health of the graphics card and the condition of the motherboard. The open hardware monitor is a free open source software that monitors. Cpu temp is read by a sensor in the socket of the motherboard. My core temps get upto about 8090c when playing certain games but my cpu is only getting 70c. Core temp is a lightweight, easytouse temperature monitor for windows computers. Core temperatures are typically the most critical temperatures to monitor. What is the difference between cpu and core temperatures.
They could also be using the cpu package temperature. Amd recommends the core temp program and amd overdrive for this reason. Whats the difference between cpu and cpu packages, and why is. Large temperature difference between cores on i76700k so i was planning to take my first plunge into overclocking my cpu, and i decided to run a stress test before starting to see where my baselines were. Very different temperatures on cpu cores techspot forums. When intel, amd and tech articles mention cpu temperature, they are referring to tcase unless otherwise stated. It is responsible for all the core functions such as arithmetical, logical and control operations. Per core cpu performance improved by roughly 50 percent over amds previous fxseries parts, and suddenly things became very interesting in the cpu space. Under heavy load both temperatures should be reliable, but at idle many modern amd processors measure unrealistically low core temperatures e. Large temperature difference between cores on i76700k. While they both serve and act as our computers computing component, they do have a few differences that could further explain the speed and efficiency of your computer. Processor or the cpu is like the brain of the computer system. Presumably, most people shopping for a higherend consumer cpu would be more inclined to consider a lessexpensive option than a core i99900k, like intels core i79700k or amds ryzen 7 2700x.
Weird difference between cpu package and core temp. How to monitor your computers cpu temperature howto geek. What is the difference between cuda core and cpu core. Since these sensors measure 2 distinct thermal levels, there is a 5c temperature difference between them, which is tcase to tjunction gradient. Big differences in cpu temperatures with different software. Real temp is a temperature monitoring program designed for all intel single core, dual core, quad core and core i7 processors.
Hwinfo is an indepth system monitoring tool that provides deep details about every piece of your pcs. The cpu temperature can be monitored by reading the core temperature sensors. A traditional processor such as a pentium processor has only one core inside the processor. Open hardware monitor core temp, fan speed and voltages in a.
