Why more and more CPU pin this reason most important
Once in a while will launch the tenth generation desktop Core have to change the pin, the pin should do more performance more? Think about it, memory channels, PCIe channels such external data path seems to be little change Well, like so many pins without increasing hot, right? In fact, at the time of previous generations is not compatible with the motherboard Core cross-mentioned small series this thing, the biggest reason the pins are always changing, in fact, is the CPU power supply problems.
To know that each generation Core Duo, especially high-end Core Duo power (note not TDP) is rising, such as i9-9900K maximum power consumption is about 250W, some media reports sneak i9-10900K measured has reached 300W. These power from where it? Yes, that is provided by pins.
Because restriction pins, contacts, chip design, each pin interfaces generally not more than LGA current. 5A, it looks like the power of 6W ~ 8W, as CPU power increase, the number of pins must increase with the power supply. AMD can hold with the AM4 interfaces, one important reason is inserted a metal pin small needle stick, high sequins supply current (power) to use than many of the LGA.
Carefully calculate, it seems to increase 10 to 50W of power pins will be enough, so why add the 50 breath it? This is because the power supply is not its ground together with the maximum current of the power supply, the power supply part to be dispersed (red blocks), there is a demand in the processor module when some quick supply. Another part of the ground pin (Vss) to surround the high-frequency output pins, to help shield the interference (the black blocks).
In addition, with the upgrade power consumption, generally taken to reduce the CPU power, core voltage way to reduce heat, to enhance the current tolerance. Thus in the case where the same pin current, the power supply is even lower (power = voltage × current), also need to use the same power more pins.
Well, since pins upgrade is inevitable, we installed the time to pay attention Shane? The first is the time of purchase to pay more attention to the motherboard power supply module, since the pin description power increases more and more complex, fine, then performance and quantity must be enough power supply module, such as the future of LGA 1200 motherboard want to be on high-end processors, 10 phase power supply is required, 14, 16 are coupled with relatively good power supply element that is more reliable.
The other is more pins more intensive, CPU installation was even more careful, Twist after the original accord, move a move must get rid of the habit, it will easily cause stitch dislocation and distortion, should try to make a one-time pinpoint position, mounted vertically.
