Ryzen 9 3900 (non X)

[pc-guy]

Anyone got any experiences with these (3900 non X parts)? Looks like OEM parts only. But it is £100 cheaper than 3900x (about the same price as a 3800x) on an OEM site I found.

just curious to see if anyone had one of those pre-built and how the CPU faired in terms of boosts and voltages.

thanks

3900 is OEM so no cooler. You can’t buy them retail. They only come in CPU and board bundle or prebuilt PCs

3900 and 3900x have same base clock but the boost is different. 4.3GHz vs 4.6GHz. TDP is 65vs105.

but obviously everything can be overridden in manual overclock. Just wondering if anyone got any feedback on that. £100 is a fair bit of dosh.

There s an article that nandtech has got the 3900 clicked to 5.4/5.5Ghz under liquid nitro. And only 100MHz behind the 3900x but no details on volts, IF, ram speed etc. So can’t tell if the non-x is actually performance crippling.

Would expext those OEM parts to be worser bin.
Also lower TDP is certain to hurt boost clocks under multicore load.

Not according to Tom’s hardware.

Although some of their test results don’t tally up but direct comparison between 3900x and 3900 is interesting.

@£320 this is the same amount of £/core as 3600. Boosts higher as well more cache etc etc.

currently a bundle deal of 3900 with B450 tomahawk can be had for £440

or ASUS ROG B550 Strix for £520
