The Radeon RX 6600, one of many finest graphics playing cards available on the market, has emerged in a uncommon MXM (Cellular PCI Categorical Module) kind issue. Redditor SurfaceDockGuy (opens in new tab) has in some way acquired a Radeon RX 6600 MXM and tore it down to look at its inside. Whereas the MXM kind issue usually is discovered inside laptops, this explicit Radeon RX 6600 module might be for eGPU enclosures or servers that settle for the format.
AMD’s Navi 23 silicon, which measures 237 mm², resides on the coronary heart of the Radeon RX 6600. The Redditor famous that the Radeon RX 6600 MXM makes use of a 10-phase energy supply system with what seems to be two NCP81022 4+1 voltage controllers in tandem. Subsequently, It is believable that seven phases energy the Vcore, whereas the remaining three phases cater to the GDDR6 or SoC. Moreover, an built-in OnSemi 55A energy stage administers every section, as SurfaceDockGuy reckons. Subsequently, it could appear that HIS (Hightech Data System Restricted) is the producer behind the Radeon RX 6600 MXM.
In keeping with the Redditor, the AMD driver detects the MXM as a vanilla Radeon RX 6600, so the variety of stream processors is unbroken. As well as, it arrives with 4 16Gb Micron GDDR6 reminiscence modules. Nonetheless, the TDP is considerably decrease, given the compact kind issue. The firmware reportedly fixes the TDP at 75W. For comparability, the desktop Radeon RX 6600 encompasses a 132W TDP, whereas the cellular Radeon RX 6600M sits at 100W. Subsequently, the MXM variant is the slowest of the trio. Nonetheless, the Redditor might unlock the facility restrict by way of MorePowerTool, a well-liked Radeon tweaking, and overclocking device, and set the TDP previous 130W.
SurfaceDockGuy did not present any benchmark outcomes for the Radeon RX 6600 MXM. Nonetheless, he claims that it matches the efficiency of a desktop Radeon RX 6600. So it is smart the Redditor pushed the MXM over 130W, which places it in the identical alley because the common Radeon RX 6600 with a 132W TDP score.
The Radeon RX 6600 MXM comes with a cooling system that consists of a heatsink, three copper warmth pipes, and a tiny 40mm cooling fan from FirstD. SurfaceDockGuy highlighted that the efficiency is on par along with his desktop Radeon RX 6600, which encompasses a thrice bigger heatsink and double cooling followers. The PCB lacks a fan header, so the 40mm fan connects to a number controller board on the flipside of the MXM interface.
It is not shocking that distributors nonetheless supply the latest-generation graphics playing cards within the MXM format. There are a number of Nvidia Ampere MXM choices available on the market, however they aim the skilled market with fashions such because the RTX A4500 or RTX A2000. Subsequently, it is the primary time we have seen one among AMD’s Radeon RX 6000 (Massive Navi), a gaming graphics card, arrive in an MXM kind issue.
