It goes without saying that XPUs are now hungrier for power more than ever. With the latest trending technologies featuring specs like artificial intelligence, machine learning, and mass data mining, the demand for more powerful XPUs is now a rising need! So, what are the chip manufacturers developing to meet this demand?
NVidia impressed the gaming community with their new white paper on multi-chip modules. Even their rival brand, AMD, is showing great promises with Navi GPUs. Although, they are still sticking to the traditional monolithic die.
As an engineer, you might want to ask the obvious question—what’s the best option to boost XPUs?
Here are the best three options you should look into.
Vicor is a renowned name within the electronics industry. They improved Point-of-Load regulation technology to meet the demand of XPUs and created the modular current multipliers (MCMs).
They have three main key features that contributed to their “Product of the Year” award from Electronic Products last year. These features include higher current delivery (both peak and average), 10 times reduced resistance between the motherboard and the XPU socket, and 10 times less power pin count of the XPUs.
They are calling themselves the inventor of the “last inch power delivery network.” Currently, they have launched two power-on-package solution modules:
- MCM3208S59Z01A6C00 modular current multiplier with MCD3509S60E59D0C01 modular current driver (the 320 amp variant)
- MCM4608S59Z01B5T00 modular current multiplier with MCD4609S60E59H0T00 modular current driver (the 600 amp variant)
The modular current multipliers convert low current 48-VDC to a high current supply, ranging from 160 A to 640 A. The device can function at a temperature ranging from -40°C to 125°C. Vicor just introduced a more efficient way to power up XPUs that far outperforms older technologies.
Big names like IBM, NVidia, Alphabet, and Pezy have already adopted this new technology. In fact, this device is the major game changer in the battle of NVidia and AMD.
VTM™ Current Multipliers With PRM™ Regulators
Here’s another XPU wonder from Vicor. Although, this technology is quite older compared to Power-on-Package. It is based on the traditional point-of-load current multiplier family. It can deliver a wide range of current outputs, from 6A to 135A. There are packages for both half and full chips.
The ZCS/ZVS Sine Amplitude Converter™ technology is key behind the impressive rate of 96% efficiency. It gives even better output compared to the conventional DC-DC converters if you can combine it with the PRM™ regulator from the same brand.
BCM™ High Voltage Bus Converter Module
We cannot attempt to establish a safer environment without a DC-DC bus converter. This module can operate from a nominal input of 380 VDC and can deliver a SELV secondary output. Current versions have 48 V output; however, the company is working on the 12 V and 24 V versions.
With the 4414 VIA model, the output current can surge up to 125 A. The outstanding 98% efficiency makes it a desirable product.
If you are looking for something out of the box, you should better stick with Vicor’s Power-on-Package. There is no other product on the market to offer modular current multiplier. MCM technology is entirely new, and there is a lot to learn here.
